- Study Purpose The DRAGON 1 trial aims to assess training, implementation, safety and feasibility of combined portal- and hepatic-vein embolization (PVE/HVE) to accelerate future liver remnant (FLR) hypertrophy in patients with borderline resectable colorectal cancer liver metastases. Methods The DRAGON 1 trial is a worldwide multicenter prospective single arm trial. The primary endpoint is a composite of the safety of PVE/HVE, 90-day mortality, and one year accrual monitoring of each participating center. Secondary endpoints include: feasibility of resection, the used PVE and HVE techniques, FLR-hypertrophy, liver function (subset of centers), overall survival, and disease-free survival. All complications after the PVE/HVE procedure are documented. Liver volumes will be measured at week 1 and if applicable at week 3 and 6 after PVE/HVE and follow-up visits will be held at 1, 3, 6, and 12 months after the resection. Results Not applicable. Conclusion DRAGON 1 is a prospective trial to assess the safety and feasibility of PVE/HVE. Participating study centers will be trained, and procedures standardized using Work Instructions (WI) to prepare for the DRAGON 2 randomized controlled trial. Outcomes should reveal the accrual potential of centers, safety profile of combined PVE/HVE and the effect of FLR-hypertrophy induction by PVE/HVE in patients with CRLM and a small FLR.

- Background Colorectal cancer is one the most common cancers in the western world with increasing incidence. Approximately 50% of the patients develop liver metastases. Resection of liver metastases is the treatment of choice although almost half of the resected patients get recurrence in the liver. Methods The ASAC trial is a Scandinavian, multicentre, double-blinded, randomized, placebo-controlled study to determine whether adjuvant treatment with low-dose aspirin (acetylsalicylic acid (ASA)) can improve disease-free survival in patients treated for colorectal cancer liver metastases (CRCLM). Up to 800 patients operated for CRCLM will be randomized to Arm#1 ASA 160 mg once daily or Arm#2 Placebo, for a period of 3 years or until disease recurrence. The patients will be recruited at all major hepatobiliary surgical units in Norway, Sweden and Denmark and have follow-up according to standard of care and the National Guidelines. Discussion The ASAC trial will be the first clinical interventional trial to assess the potential beneficial role of ASA in recurrence of CRCLM and survival. ASA is an inexpensive, well-tolerated and easily accessible drug that will be highly potential as adjuvant drug in secondary prevention of CRCLM if the study shows a beneficial effect. We will also determine the effect of ASA as adjuvant treatment on Health-Related Quality of Life and the cost-effectiveness.

- Background and objective: Gallbladder cancer (GBC) is a rare malignancy in the Nordic countries and no common Nordic treatment guidelines exist. This study aimed to characterize the current diagnostic and treatment strategies in the Nordic countries and disclose differences in these strategies. Methods: This was a survey study with a cross-sectional questionnaire of all 19 university hospitals providing curative-intent surgery for GBC in Sweden, Norway, Denmark, and Finland. Results: In all Nordic countries except Sweden, neoadjuvant/downstaging chemotherapy was used in GBC patients. In T1b and T2, majority of the centers (15-18/19) performed extended cholecystectomy. In T3, majority of the centers (13/19) performed cholecystectomy with resection of segments 4b and 5. In T4, majority of the centers (12-14/19) chose palliative/oncological care. The centers in Sweden extended lymphadenectomy beyond the hepatoduodenal ligament, whereas all other Nordic centers usually limited lymphadenectomy to the hepatoduodenal ligament. All Nordic centers except those in Norway used adjuvant chemotherapy routinely for GBC. There were no major differences between the Nordic centers in diagnostics and follow-up. Conclusions: The surgical and oncological treatment strategies of GBC vary considerably between the Nordic centers and countries.

Tidskriftsartikel (refereegranskat)abstract
- Background: Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide. Methods: This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters. Results: A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 percent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 percent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 percent; however, it was 41 per cent in low-to-middle-compared with 19 per cent in very high-HDI countries. Conclusion: Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761).

Colorectal Liver Metastases – Different Aspects on Treatment with Associated Liver Partition and Portal Vein Ligation for Staged Hepatectomy and on Portal Vein Occlusion
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: For patients with colorectal liver metastases (CRLM), the only treatment with a possibility for long-term survival and cure is radical resection. The majority of patients are at the time of diagnosis not assessed as resectable because they have advanced disease in the liver or unresectable extrahepatic disease or are too frail to withstand liver surgery. Patients who at the time of diagnosis are not assessed as resectable may be treated with conversion chemotherapy to downsize the tumor burden and render the patient eligible for resection. One concern with chemotherapy administered preoperatively has been the potential negative effect on the future liver remnant (FLR), especially for patients with a low volume of the FLR who are undergoing techniques to increase the volume. Established techniques to increase the volume are portal vein occlusion (PVO) and two-staged hepatectomy (TSH). A more recent method is Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS). Due to the relative novelty of ALPPS, the long-term oncological results are not known. For patients with CRLM, resection of liver metastases is more favorable from a health economic perspective than palliative treatment and results in a higher quality of life than palliative chemotherapy. For patients undergoing ALPPS as well as TSH, the data are scarce. Aim: The aim of the first study was to determine whether preoperative chemotherapy has a negative impact on the volume increase for patients undergoing ALPPS. The aim of the second study was to analyze the temporal course of the volume increase in the FLR for patients undergoing PVO. The aim of the third study was to study the long-term outcome for patients randomized to ALPPS or TSH. The aim of the fourth study was to perform a health economic analysis of patients randomized to ALPPS or TSH. Methods: The first study was based on data from the ALPPS registry, which is an international registry initiated 2012. All patients included in the registry between 2012 and 2016 were included. The patients were divided into the following four groups: no preoperative chemotherapy, 1 regimen of neoadjuvant chemotherapy, more than 1 regimen, and more than 1 regimen with the addition of monoclonal antibodies. The volume increase between interventions 1 and 2 was analyzed. In the second study, a retrospective analysis was performed of patients randomized to TSH. Forty-eight patients were included. The volume increase of the FLR was analyzed as the kinetic growth rate (KGR). The KGR was calculated from PVO until radical hepatectomy or exclusion, as well as between the first and second radiological evaluations. In the third and fourth studies, patients randomized to ALPPS and TSH were included. In the third study, survival, as well as factors affecting the outcome, were analyzed. In the fourth study, a calculation of resource use was performed, as was an analysis of health-related quality of life (HRQoL) for the groups. Results: In the first study, it was found that chemotherapy had no negative impact on the volume increase for patients undergoing ALPPS. In the second study, it was found that the volume increase of the FLR was largest the first week after ALPPS. In the third study, it was found that patients randomized to ALPPS had a longer survival than those randomized to TSH. Of the factors affecting the outcome, resection of liver metastases had a significant impact. In the fourth study, no significant difference could be found in resource use or HRQoL for patients randomized to ALPPS over TSH. Conclusion: Patients with advanced CRLM undergoing ALPPS should receive preoperative chemotherapy, if indicated. For those undergoing PVO, early evaluation is crucial to evaluate the volume increase, and for those with insufficient increase, additional techniques to increase the volume should be considered. Resection of liver metastases is an important factor to improve the outcome. Further studies are warranted to conclude whether ALPPS or TSH is most effective from a health economic perspective.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundPortal vein occlusion (PVO) is an established method to increase the volume of the future liver remnant (FLR). The main reasons for not proceeding to radical hepatectomy are lack of volume increase and tumor progression due to a wait-time interval of up to 8weeks. The hypothesis was that the increase in FLR volume is not linear and is largest during the first weeks.MethodsPatients with colorectal liver metastases (CRLM) and standardized future liver remnant (sFLR) <30% treated with PVO were prospectively included. All patients had at least one CT evaluation before radical hepatectomy.ResultsForty-eight patients were included. During the first week after PVO, the kinetic growth rate (KGR) was 5.4 (4), compared to 1.5 (+/- 2) between the first and second CT (p<0.05). For patients reaching adequate FLR and therefore treated with radical hepatectomy, the KGR was 7 (+/- 4) the first week, compared to 4.3 (+/- 2) for patients who failed to reach a sufficient volume (p=0.4). During the interval between the first and second CT, the KGR was 2.2 (+/- 2), respectively (+/- 0.1) (p=0.017).Discussion p id=Par4 The increase in liver volume after PVO is largest during the first week. As KGR decreases over time, it is important to shorten the interval between PVO and the first volume evaluation; this may aid in decision-making and reduce unnecessary waiting time.

- Background: Incidental gallbladder cancer is a rare event, and its prognosis is largely affected by the tumour stage and treatment. The aim of this study was to analyse the management, treatment and survival of patients with incidental gallbladder cancer in a national cohort over a decade. Methods: Patients were identified through the Swedish Registry of Gallstone Surgery (GallRiks). Data were cross-linked to the national registry for liver surgery (SweLiv) and the Cancer Registry. Medical records were collected if registry data were missing. Survival was measured as disease-specific survival. The study was divided into two intervals (2007–2011 and 2012–2016) to evaluate changes over time. Results: In total, 249 patients were identified with incidental gallbladder cancer, of whom 92 (36·9 per cent) underwent re-resection with curative intent. For patients with pT2 and pT3 disease, median disease-specific survival improved after re-resection (12·4 versus 44·1 months for pT2, and 9·7 versus 23·0 months for pT3). Residual disease was present in 53 per cent of patients with pT2 tumours who underwent re-resection; these patients had a median disease-specific survival of 32·2 months, whereas the median was not reached in patients without residual disease. Median survival increased by 11 months for all patients between the early and late periods (P = 0·030). Conclusion: Re-resection of pT2 and pT3 incidental gallbladder cancer was associated with improved survival, but survival was impaired when residual disease was present. A higher re-resection rate and more R0 resections in the later time period may have been associated with improved survival.

Tidskriftsartikel (refereegranskat)abstract
- Objective Fast-track concepts have been implemented in hepatopancreatobiliary surgery cancer care to improve postoperative recovery. For optimal postoperative care, patient participation is also required. The aim was to investigate and analyse whether an intervention with patient-owned fast-track protocols (PFTPs) may lead to increased patient participation and improve information for patients who underwent surgery for hepatopancreatobiliary cancer. Methods A quantitative comparative design with a control and intervention group was used. The participants in the intervention group followed a PFTP during their admission. After discharge, the patients answered a questionnaire regarding patient participation. Data analyses were performed with descriptive statistics and ANCOVA. Results The results are based on a total of 222 completed questionnaires: 116 in the control group and 106 in the intervention group. It is uncertain whether the PFTP increased patient participation and information, but its use may indicate an improvement for the patient group. Conclusion A successful implementation strategy for the use of PFTP, with daily reconciliations, could be part of the work required to improve overall satisfaction with patient participation.

Tidskriftsartikel (refereegranskat)abstract
- Background: Early detection of coronary atherosclerosis using coronary computed tomography angiography (CCTA), in addition to coronary artery calcification (CAC) scoring, may help inform prevention strategies. We used CCTA to determine the prevalence, severity, and characteristics of coronary atherosclerosis and its association with CAC scores in a general population.Methods: We recruited 30 154 randomly invited individuals age 50 to 64 years to SCAPIS (the Swedish Cardiopulmonary Bioimage Study). The study includes individuals without known coronary heart disease (ie, no previous myocardial infarctions or cardiac procedures) and with high-quality results from CCTA and CAC imaging performed using dedicated dual-source CT scanners. Noncontrast images were scored for CAC. CCTA images were visually read and scored for coronary atherosclerosis per segment (defined as no atherosclerosis, 1% to 49% stenosis, or ≥50% stenosis). External validity of prevalence estimates was evaluated using inverse probability for participation weighting and Swedish register data.Results: In total, 25 182 individuals without known coronary heart disease were included (50.6% women). Any CCTA-detected atherosclerosis was found in 42.1%; any significant stenosis (≥50%) in 5.2%; left main, proximal left anterior descending artery, or 3-vessel disease in 1.9%; and any noncalcified plaques in 8.3% of this population. Onset of atherosclerosis was delayed on average by 10 years in women. Atherosclerosis was more prevalent in older individuals and predominantly found in the proximal left anterior descending artery. Prevalence of CCTA-detected atherosclerosis increased with increasing CAC scores. Among those with a CAC score >400, all had atherosclerosis and 45.7% had significant stenosis. In those with 0 CAC, 5.5% had atherosclerosis and 0.4% had significant stenosis. In participants with 0 CAC and intermediate 10-year risk of atherosclerotic cardiovascular disease according to the pooled cohort equation, 9.2% had CCTA-verified atherosclerosis. Prevalence estimates had excellent external validity and changed marginally when adjusted to the age-matched Swedish background population.Conclusions: Using CCTA in a large, random sample of the general population without established disease, we showed that silent coronary atherosclerosis is common in this population. High CAC scores convey a significant probability of substantial stenosis, and 0 CAC does not exclude atherosclerosis, particularly in those at higher baseline risk.

- Background Consistent data on clinical features, treatment modalities and long-term survival in patients with hepatocellular carcinoma (HCC) using nationwide quality registers are lacking. This study aimed to describe treatment patterns and survival outcomes in patients diagnosed with HCC using a national maintained database. Methods Characteristics and treatment patterns in patients diagnosed with HCC and registered in the national register of liver and bile duct tumours (SweLiv) between 2009 and 2016 were reviewed. Overall survival (OS) was estimated using Kaplan-Meier analysis and the log rank test to compare subgroups for clinical features, treatment modalities and outcomes according to the year of treatment. Results A total of 3376 patients with HCC were registered over 8 years, 246 (7 center dot 3 per cent) of whom underwent transplantation. Some 501 (14 center dot 8 per cent) and 390 patients (11 center dot 6 per cent) had resection and ablation as primary treatment. Transarterial chemoembolization and systemic sorafenib treatment were intended in 476 (14 center dot 1 per cent) and 426 patients (12 center dot 6 per cent) respectively; the remaining 1337 (39 center dot 6 per cent) were registered but referred for best supportive care (BSC). The 5-year survival rate was approximately 75 per cent in the transplantation group. Median OS was 4 center dot 6 (i.q.r. 2 center dot 0 to not reached) years after resection and 3 center dot 1 (2 center dot 3-6 center dot 7) years following ablation. In patients referred for palliative treatment, median survival was 1 center dot 4 (0 center dot 8-2 center dot 9), 0 center dot 5 (0 center dot 3-1 center dot 2) and 0 center dot 3 (0 center dot 1-1 center dot 0) years for the TACE, sorafenib and BSC groups respectively (P amp;lt; 0 center dot 001). Median survival was 0 center dot 9 years for the total HCC cohort in 2009-2012, before publication of the Swedish national treatment programme, increasing to 1 center dot 4 years in 2013-2016 (P amp;lt; 0 center dot 001). Conclusion The survival outcomes reported were in line with previous results from smaller cohorts. The introduction of national guidelines may have contributed to improved survival among patients with HCC in Sweden.

- PurposePatients’ involvement in their own care is important for those with upper abdominal tumours. Care is often conducted according to standardized fast-track care programs (FTCP), and a shorter hospital stay is one of the goals. However, there is no research providing an in-depth perspective on patients’ experiences of involvement in care. In this qualitative study, we explored experiences of involvement among patients who had surgery for upper abdominal tumours and were cared for according to an FTCP.MethodsQualitative in-depth face-to-face interviews about patient involvement in care were conducted with 20 patients who had surgery for the liver, bile duct, or pancreatic cancer using an open-interview guide.ResultsThe most important findings are that customized information and active dialogue about care decisions stimulate patient involvement. We identified three themes from the analysed data: involvement depended on the quality of information, communication and involvement during the care period, and safety at discharge.ConclusionsIndividualized care and continuous information about treatment and care goals in the FTCP during the care process create trust between patients and healthcare professionals and increase patient experiences of involvement.

High resection rate improves overall survival in elderly patients with pancreatic head cancer - A cohort study
- 2021
-
Ingår i: International Journal of Surgery Open. - : Elsevier Science Ltd. - 2405-8572. ; 34
-
Tidskriftsartikel (refereegranskat)abstract
- Background: There is evidence that a high hospital volume of pancreaticoduodenectomy improves short-and long-term outcomes, but there are few population-based studies on the effect of a high resection rate in the population. The aim of this national, observational study was primarily to investigate differences in overall survival among elderly patients with cancer in the pancreatic head between high and low resection rate groups and secondarily to determine if counties with high resection rates of pancreaticoduodenectomy had more severe complications after surgery. Materials and methods: All patients in the Swedish National Registry for tumours in the pancreatic and periampullary region diagnosed between 2010 and 2018 with pancreatic head cancer were included in this retrospective cohort study. Patients were divided into low and high resection rate groups according to the yearly resection rates in the respective counties. For operative outcomes, all patients who had undergone pancreaticoduodenectomy were included regardless of diagnosis. The primary outcome of the study was overall survival among patients aged >= 70 years with pancreatic head cancer. Results: Among 13 933 patients in the registry, 7661 were 70 years or older, of whom 3006 had pancreatic head cancer. Overall survival was longer in high resection rate groups for patients aged >= 70 years, as for the age subgroups 70-79 years and >= 80 years (all p < 0.001). Among patients who had undergone pancreaticoduodenectomy aged >= 80 years the high resection rate counties showed an increased rate of severe complications, but no increase in 90-day mortality. Conclusion: High resection rate groups show a significantly longer overall survival among elderly patients with pancreatic head cancer in Sweden. This implies that there could be a survival benefit from increasing resections in low resection rate groups. (C) 2021 The Author(s). Published by Elsevier Ltd on behalf of Surgical Associates Ltd.

There Is No Increase in Perioperative Mortality After Pancreaticoduodenectomy in Octogenarians : Results From the Swedish National Registry for Tumors in the Pancreatic and Periampullary Region
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of this observational study was to compare postoperative mortality and complications between octogenarians and younger patients following pancreaticoduodenectomy (PD).Summary Background Data: With the growing elderly population and improved operative and postoperative results, PD is performed more frequently in octogenarians. Despite recent studies, it is uncertain whether elderly patients experience worse postoperative outcomes than younger patients.Methods: All patients registered in the Swedish National Registry for tumors in the pancreatic and periampullary region from 2010 to 2018 who underwent PD were included in the analysis.Results: Out of 13,936 patients included in the registry, 2793 patients underwent PD and were divided into the following age groups: <70 (n = 1508), 70–79 (n = 1137), and ≥80 (n = 148) years old. There was no significant difference in in-hospital, 30- or 90-day mortality among groups. The 2 older groups had a higher rate of medical and some surgical complications but not a significantly higher rate of complications ≥IIIa according to the Clavien-Dindo classification system. The 2 older groups had lower body mass index, higher American Society of Anesthesiologists and Eastern Cooperative Oncology Group scores, lower smoking rates, and a higher rate of preoperative biliary drainage than the <70-year-old group (all P < 0.001). The operation time was shorter in the oldest group.Conclusions: Despite the worse preoperative condition of octogenarians than younger patients, short-term mortality and serious complications were not increased. The shorter operation time, however, may indicate that patients in the oldest group were more strictly selected. With careful preoperative consideration, especially regarding cardiovascular morbidity, more octogenarians can potentially be safely offered PD.

Forskningsöversikt (refereegranskat)abstract
- Background: Minimally invasive distal pancreatectomy (MIDP) has been suggested to reduce postoperative outcomes as compared to open distal pancreatectomy (ODP). Recently, the first randomized controlled trials (RCTs) comparing MIDP to ODP were published. This individual patient data meta analysis compared outcomes after MIDP versus ODP combining data from both RCTs. Methods: A systematic literature search was performed to identify RCTs on MIDP vs. ODP, and individual patient data were harmonized. Primary endpoint was the rate of major (Clavien-Dindo > III) complications. Sensitivity analyses were performed in high-risk subgroups. Results: A total of 166 patients from the LEOPARD and LAPOP RCTs were included. The rate of major complications was 21% after MIDP vs. 35% after ODP (adjusted odds ratio 0.54; p = 0.148). MIDP significantly reduced length of hospital stay (6 vs. 8 days, p = 0.036), and delayed gastric emptying (4% vs. 16%, p = 0.049), as compared to ODP. A trend towards higher rates of postoperative pancreatic fistula was observed after MIDP (36% vs. 28%, p = 0.067). Outcomes were comparable in high-risk subgroups. Conclusion: This individual patient data meta-analysis showed that MIDP, when performed by trained surgeons, may be regarded as the preferred approach for distal pancreatectomy. Outcomes are improved after MIDP as compared to ODP, without obvious downsides in high-risk subgroups.

- Fast-track programmes are aimed at improving perioperative care. The purpose of this study was to identify and explore patient participation among patients who had surgery for liver, bile duct or pancreatic cancer and followed a fast-track programme. A total of 116 questionnaires to investigate patient participation were analysed. Information was important for the patients, as was having the opportunity to ask questions and express personal views. The results showed differences by sex; men responded to a greater extent that they did not want to make decisions as a patient (p = 0.044) and that they had been motivated to take more responsibility for their future health (p = 0.011). Patients with pancreatic cancer discussed treatment goals with doctors to a greater extent than did patients with liver cancer (p = 0.041). Half of the patients perceived that they had not been involved in their care planning after discharge but had a desired to be involved. This seems to be an important point to improve in future care, and also that professionals should be aware of patients' needs for information and participation, especially at discharge.

Incidental Gallbladder Cancer : Incidence, predictors, management and outcome in a Swedish population
- 2019
-

- Background: Cholecystectomy is a common surgical procedure and incidental gallbladder cancer is a rare and unexpected finding at a cholecystectomy performed upon benign indications. Whether to perform routine or selective histopathology of the gallbladder specimen is still a subject for discussion. The prognosis of gallbladder cancer is largely affected by tumour stage and treatment.Aims: The overall aim was to study whether routine histological examination of the gallbladder specimen is of clinical and health economic value; determine if there are any predictive factors of incidental gallbladder cancer at benign cholecystectomy and compare the management and outcome of incidental gallbladder cancer patients in Sweden.Methods: All studies were based on registry data from GallRiks (The Swedish Registry for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography) between 2007 and 2016, with some modifications between studies. Complemental cross-linkage was made to national registries, and medical records were reviewed. Papers I, II and III were population-based observational studies with prospectively and retrospectively collected data. Paper IV was a health economic evaluation based on the results from papers I and III.Results and conclusions: Hospitals submitting >75 per cent of gallbladder specimens diagnosed a higher proportion of incidental gallbladder cancer than did hospitals submitting ≤25 per cent of samples (paper I). Incidental gallbladder cancer was more prevalent in older patients, women and patients with acute or previous cholecystitis, as well as ongoing jaundice. The risk model based on predictive preoperative factors was further improved by adding a macroscopic assessment of the gallbladder (paper II). Predictive factors for gallbladder cancer appeared to have an impact on which specimens were submitted in hospitals with a selective approach of histopathology (paper I). For pT2 and pT3 patients, re-resection improved diseasespecific survival, although these groups differed in terms of age and comorbidity (paper III). Residual disease was an independent factor for impaired survival. A change to routine histopathology of gallbladder specimens in Sweden would lead to increased costs with little improved health outcomes. Instead, a more standardized approach to selective histology would be needed (paper IV).

- Factors determining severity of acute pancreatitis (AP) are poorly understood. Oxidative stress causes acinar cell injury and contributes to the severity, whereas prophylactic probiotics ameliorate experimental pancreatitis. Our objective was to study how probiotics affect oxidative stress, inflammation, and acinar cell injury during the early phase of AP. Fifty-three male Sprague-Dawley rats were randomly allocated into groups: 1) control, 2) sham procedure, 3) AP with no treatment, 4) AP with probiotics, and 5) AP with placebo. AP was induced under general anesthesia by intraductal glycodeoxycholate infusion (15 mM) and intravenous cerulein (5 μg·kg-1·h-1, for 6 h). Daily probiotics or placebo were administered intragastrically, starting 5 days prior to AP. After cerulein infusion, pancreas samples were collected for analysis including lipid peroxidation, glutathione, glutamate-cysteine-ligase activity, histological grading of pancreatic injury, and NF-κB activation. The severity of pancreatic injury correlated to oxidative damage (r = 0.9) and was ameliorated by probiotics (1.5 vs. placebo 5.5, P = 0.014). AP-induced NF-κB activation was reduced by probiotics (0.20 vs. placebo 0.53 OD 450nm/mg nuclear protein, P < 0.001). Probiotics attenuated AP-induced lipid peroxidation (0.25 vs. placebo 0.51 pmol malondialdehyde/mg protein, P < 0.001). Not only was AP-induced glutathione depletion prevented (8.81 vs. placebo 4.1 μmol/mg protein, P < 0.001), probiotic pretreatment even increased glutathione compared with sham rats (8.81 vs. sham 6.18 μmol/mg protein, P < 0.001). Biosynthesis of glutathione (glutamate-cysteine-ligase activity) was enhanced in probiotic-pretreated animals. Probiotics enhanced the biosynthesis of glutathione, which may have reduced activation of inflammation and acinar cell injury and ameliorated experimental AP, via a reduction in oxidative stress.

- Leverkirurgi har under de senaste 10-15 åren ökat påtagligt, i både omfattning och antal operationer. Detta beror framför allt på förbättringar inom kirurgi, onkologi och anestesiologi. De patienter som blir föremål för leverkirurgisk behandling har tumörer, vanligen maligna eller premaligna. Primär levercancer, utgående från hepatocyter, är relativt sällsynt i Sverige med cirka 500 nya fall per år. Behandlingen av dessa är beroende av tumörutbredning, patientens funktionsgrad samt graden av bevarad leverfunktion. Den vanligaste maligna tumören i levern är en metastas. Den största patientgruppen med metastaser i levern är de med kolorektal cancer och det är i många fall motiverat att operera metastaserna om de inte är generellt spridda. Patienter med levercirros, vanligen orsakad av alkoholmissbruk, hepatit B eller hepatit C, löper hög risk att få flera allvarliga komplikationer, som leversvikt med encefalopati och ascetes. Den vanligaste komplikationen vid portal hypertension är dock blödning från esofagusvaricer som kan kräva behandling i flera steg. De behandlas i det akuta skedet endoskopiskt med sklerosering eller gummibandsligatur och därefter trycksänkning med läkemedel. Om behandlingen är otillräcklig kan man komprimera varicerna med en självexpanderande stent och hypertensionen kan få en mer definitiv lösning i att att en shunt sätts in.

Forskningsöversikt (refereegranskat)abstract
- Objective: To evaluate existing evidence regarding surgical treatments for gallbladder cancer in a Health Technology Assessment. A specific aim was to evaluate whether extended surgery regarding liver, lymph nodes, bile duct, and adjacent organs compared with cholecystectomy alone in the adult patient with gallbladder cancer in early and late stages implies improved survival. Methods: In April 2015 and updated in June 2016, a systematic literature search was conducted in PubMed, Embase, and the Cochrane Library. Two authors independently screened titles, abstracts, and full-text articles. The certainty of evidence was evaluated according to GRADE. Main results: Forty-four observational studies (non-randomised, controlled studies) and seven case series were included. Radical resection, including liver and lymph node resection, compared with cholecystectomy alone showed significantly better survival for patients with stages T1b and above. All studies had serious study limitations and the certainty of evidence was very low (GRADE circle plus(ooo)). A survival benefit seen in patients with stage T1b or higher with lymph node resection, was most evident in stage T2, but the certainty of evidence was low (GRADE circle plus circle plus(oo)). It is uncertain whether routine bile duct resections improve overall survival in patients with gallbladder cancer stage T2-T4 (GRADE circle plus(ooo)). Conclusion: Data indicate that prognosis can be improved if liver resection and lymph node resection is performed in patients with tumour stage T1b or higher. There is no evidence supporting resection of the bile duct or adjacent organs if it is not necessary in order to achieve radicality.

- AimThis study investigated healthcare professionals attitudes and perceptions towards the familys participation in surgical cancer care. DesignA prospective mixed method study. MethodsThe study was conducted at three hospitals in Sweden with registered nurses, assistant nurses and surgeons. Data included 43 completed Families Importance in Nursing Care (FINC-NA) questionnaires answered by registered nurses and qualitative data from 14 interviews with surgeons and assistant nurses. Data analysis was performed according to the Creswell convergent parallel mixed method. ResultsBoth quantitative and qualitative data demonstrated that the family was an important resource in nursing care, was highly valued as a conversational partner and had resources that should be considered. Each family should be supported in determining their role and as implements for maintaining a functioning family constellation and increasing their participation. Patient or Public ContributionNo patient or public contribution.
