- Objectives: Most patients with pancreatic cancer who have undergone surgical resection eventually develop disease recurrence. This study aimed to investigate whether there is evidence to support routine surveillance after pancreatic cancer surgery, with a secondary aim of analyzing the implementation of surveillance strategies in the Nordic countries.Materials and Methods: A scoping review was conducted to identify clinical practice guidelines globally and research studies relating to surveillance after pancreatic cancer resection. This was followed by a survey among 20 pancreatic units from four Nordic countries to assess their current practice of follow-up for operated patients.Results: Altogether 16 clinical practice guidelines and 17 research studies were included. The guidelines provided inconsistent recommendations regarding postoperative surveillance of pancreatic cancer. The clinical research data were mainly based on retrospective cohort studies with low level of evidence and lead-time bias was not addressed. Active surveillance was recommended in Sweden and Denmark, but not in Norway beyond the post-operative/adjuvant period. Finland had no national recommendations for surveillance. The Nordic survey revealed a wide variation in reported practice among the different units. About 75% (15 of 20 units) performed routine postoperative surveillance. Routine CA 19-9 testing was used by 80% and routine CT by 67% as part of surveillance. About 73% of centers continued follow-up until 5 years postoperatively.Conclusion: Evidence for routine long-term (i.e. 5 years) surveillance after pancreatic cancer surgery remains limited. Most pancreatic units in the Nordic countries conduct regular follow-up, but protocols vary.

- Background: Despite improvements in therapy regimens over the past decades, overall survival rates for pancreatic and periampullary cancer are poor. Specific cancer registries are set up in various nations to regional differences and to enable larger prospective trials. The aim of this study was to describe the Swedish register, including possibilities to improve diagnostic work-ups, treatment, and follow-up by means of the register.Methods: Since 2010, all patients with pancreatic and periampullary cancer (including also patients who have undergone pancreatic surgery due to premalignant or benign lesions) have been registered in the Swedish National Periampullary and Pancreatic Cancer registry.Results: In total 9887 patients are listed in the registry; 8207 of those have malignant periampullary cancer. Approximately one-third (3282 patients) have had resections performed, including benign/premalignant resections. 30-day and 90-day mortality after pancreatoduodenectomy is 1.5% and 3.5%, respectively. The overall 3-year survival for resected pancreatic ductal adenocarcinoma is 35%. Regional variations decreased over the studied period, but still exist.Conclusion: Results from the Swedish National Registry are satisfactory and comparable to international standards. Trends over time show increasing resection rates and some improved results. Better collaboration and openness within pancreatic surgeons is an important side effect.

- Gastrointestinal (GI) complications are serious consequences of cardiac surgery. The aim of this study was to develop, evaluate and validate a new risk score model for GI complications after cardiac surgery. The risk score model, named gastrointestinal complication score (GICS), was developed using prospectively collected data from 5593 patients who underwent 5636 cardiac surgical procedures between 1996 and 2001. The model was validated on 1031 cardiac surgery patients between 2005 and 2006. The scoring system's ability to predict GI complications was estimated by receiver operating characteristic (ROC)-curves and Hosmer-Lemeshow test. Fifty GI complications were identified in 47 patients (0.8%) in the developmental data set and eight (0.8%) in the validation data set. The ROC area in the developmental data set was 0.81 with a good calibration estimated by Hosmer-Lemeshow test (p=0.89). In the validation data set, the area under the curve was 0.83. The estimated probability for the patient to develop a GI complication after cardiac surgery at a GICS >/=15 is >20% and at a GICS

ABO-Identical Blood Group Matching Has No Survival Benefit for AB Heart Transplant Recipients.
- 2015

- Although identical blood group matching is preferred, it is uncertain if this results in improved survival and, if so, how large the survival benefits are. Earlier studies have yielded conflicting results and are mostly based on single-center cohorts with few long-term results. Recipients with blood group AB are of particular interest regarding nonidentical blood group matching because they may receive organs from all blood groups. We wanted to test the hypothesis that ABO-identical matching results in superior survival in recipients with blood group AB.

-
Tidskriftsartikel (refereegranskat)abstract
- The primary objective of this study is to compare the accuracy of two risk models, International Heart Transplantation Survival Algorithm (IHTSA), developed using deep learning technique, and Index for Mortality Prediction After Cardiac Transplantation (IMPACT), to predict survival after heart transplantation. Data from adult heart transplanted patients between January 1997 to December 2011 were collected from the UNOS registry. The study included 27,860 heart transplantations, corresponding to 27,705 patients. The study cohorts were divided into patients transplanted before 2009 (derivation cohort) and from 2009 (test cohort). The receiver operating characteristic (ROC) values, for the validation cohort, computed for one-year mortality, were 0.654 (95% CI: 0.629–0.679) for IHTSA and 0.608 (0.583–0.634) for the IMPACT model. The discrimination reached a C-index for long-term survival of 0.627 (0.608–0.646) for IHTSA, compared with 0.584 (0.564–0.605) for the IMPACT model. These figures correspond to an error reduction of 12% for ROC and 10% for C-index by using deep learning technique. The predicted one-year mortality rates for were 12% and 22% for IHTSA and IMPACT, respectively, versus an actual mortality rate of 10%. The IHTSA model showed superior discriminatory power to predict one-year mortality and survival over time after heart transplantation compared to the IMPACT model.

- Although the use of induction therapy has reduced the risk of acute rejection after heart transplantation, its use may be associated with other adverse outcomes. We aimed to examine the effect of no induction (NoInd), induction with basiliximab (BAS), or induction with antithymocyte globulin (ATG) on outcome after heart transplantation. We analyzed data from the International Society for Heart and Lung Transplantation (ISHLT) registry for adult heart transplants performed between 2000 and 2013. The primary outcome was cumulative all-cause mortality, and the secondary outcome was cause-specific death. We identified 27 369 transplants whose recipients received NoInd (n = 15 688), ATG (n = 6830), or BAS (n = 4851). Over a median follow-up of 1497 days, overall 30-day mortality was 5% and 1-year mortality was 11%. Survival after transplant was similar in patients treated with NoInd compared with ATG. The survival was improved using NoInd compared with BAS (log-rank P =.040), adjustment HR = 1.11 (95% CI, 1.04-1.19). Compared to NoInd, BAS was associated with higher risk of graft failure-related deaths, HR = 1.27 (95% CI, 1.02-1.58), and ATG was associated with higher risk of malignancy-related deaths, HR = 1.18 (95% CI, 1.01-1.39). Survival of patients who received NoInd was similar to ATG and better compared with BAS. Further, the use of ATG may be associated with increased malignancy-related mortality, compared with NoInd.

- Objectives: Endoscopic retrograde cholangiopancreatography (ERCP) with failed biliary cannulation is associated with a high rate of adverse events, but the role of prophylactic antibiotics remains unclear. The primary aim was to investigate if prophylactically administered antibiotics affect the frequency of overall adverse complications in patients where biliary cannulation fails during ERCP. The secondary aim was to investigate if specific infectious complications, also were affected by the antibiotic prophylaxis.Materials and methods: We analysed data from 96,818 ERCPs (2006–2018), from the Swedish National Quality Registry of Cholecystectomy and ERCP (GallRiks), excluding ERCPs with successful cannulation (n = 88,743), missing data (n = 2,014), or on-going antibiotic therapy (n = 1,062).Results: In total 4,996 procedures were included, 2,124 received (42.5%) and 2,872 (57.5%) did not receive antibiotic prophylaxis. There were fewer overall complications in the group receiving prophylaxis (13.6% vs. 17.1%, p < .001), which corresponded to a 24% adjusted odds reduction in the multivariable analysis (odds ratio [OR] 0.76; 95% confidence interval [CI] 0.65–0.89). In the prophylaxis group, there was a lower overall rate of infectious complications (2.1% vs. 3.2%; p = .038; OR 0.68; 95% CI 0.47–0.98) and abscesses (0.8% vs. 1.4%; p = .040; OR 0.54; 95% CI 0.31–0.96). However, no significant differences were seen in the rate of cholangitis (1.3% vs. 1.7%; p = .182; OR 0.74; 95% CI 0.46–1.18).Conclusion: This national quality registry study of ERCPs with failed cannulation showed a significant reduction in overall and infectious complications when prophylactic antibiotics were administered.

Tidskriftsartikel (refereegranskat)abstract
- This is a short report of the recently published Swedish guidelines for acute pancreatitis, which are based on international guidelines as well as original publications. The report covers diagnosis, classification, treatment and follow up for patients with acute pancreatitis. Early rehydration and goal-based fluid therapy is recommended as well as oral intake of food on demand. Risk factors for development of severe disease and organ failure should be considered already in the emergency unit. Abdominal computer tomography is generally not recommended the first 5-7 days from onset of symptoms. Antibiotic therapy is only recommended when there is suspicion of or a confirmed infection. If intervention is needed for patients with moderate or severe disease a minimal-invasive step-up approach is recommended. Endoscopic Retrograde Cholangiography is generally not recommended as a treatment in the acute phase of the disease. Identification and treatment of the etiology causing acute pancreatitis is essential to prevent new episodes of the disease.
