- BackgroundAntireflux surgery is effective for the treatment of gastro-oesophageal reflux disease (GORD) but recurrence of hiatal hernia remains a challenge. In other types of hernia repair, use of mesh is associated with reduced recurrence rates. The aim of this study was to compare the use of mesh versus sutures alone for the repair of hiatal hernia in laparoscopic antireflux surgery.MethodsPatients undergoing laparoscopic Nissen fundoplication for GORD between January 2006 and December 2010 were allocated randomly to closure of the diaphragmatic hiatus with crural sutures or non-absorbable polytetrafluoroethylene mesh (CruraSoft®). The primary outcome was recurrence of hiatal hernia, as determined by barium swallow study 12 months after surgery. Secondary outcomes were: intraoperative and postoperative complications, use of antireflux medication, postoperative oesophageal acid exposure, quality of life, dysphagia and duration of hospital stay.ResultsSome 77 patients were randomized to the suture technique and 82 patients underwent mesh repair. At 1 year, the hiatal hernia had recurred in six of 64 patients (9 per cent) in the mesh group and two of 64 (3 per cent) in the suture group (P = 0·144). Reflux symptoms, use of proton pump inhibitors and oesophageal acid exposure did not differ between the groups. At 3 years, recurrence rates were 13 and 10 per cent in the mesh and suture groups respectively (P = 0·692). Dysphagia scores decreased in both groups, but more patients had dysphagia for solid food after mesh closure (P = 0·013). Quality-of-life scores were comparable between the groups.ConclusionTension-free crural repair with non-absorbable mesh does not reduce the incidence of recurrent hiatal hernia compared with use of sutures alone in patients undergoing laparoscopic fundoplication.

- BackgroundThe use of prophylactic abdominal drainage following pancreaticoduodenectomy (PD) is controversial as its therapeutic value is uncertain. However, the diagnosis of postoperative pancreatic fistula (POPF), the main cause of PD-associated morbidity, is often based on drain pancreatic amylase (DPA) levels. The aim of this study was to assess the predictive value of DPA, plasma pancreatic amylase (PPA) and serum C-reactive protein (CRP) for diagnosing POPF after PD.MethodsPatients undergoing PD with prophylactic drainage between 2008 and 2012 were studied prospectively. DPA, PPA and CRP levels were obtained daily. Differences between groups with clinically relevant POPF (International Study Group on Pancreatic Fistula (ISGPF) grade B/C) and without clinically relevant POPF (no POPF or ISGPF grade A) were evaluated. Receiver operating characteristic (ROC) analyses were performed to determine the value of DPA, PPA and CRP in prediction of POPF. Risk profiles for clinically relevant POPF were constructed and related to the intraoperative pancreatic risk assessment.ResultsFifty-nine (18·7 per cent) of 315 patients developed clinically relevant POPF. DPA, PPA and CRP levels on postoperative day (POD) 1–3 differed significantly between the study groups. In predicting POPF, the DPA level on POD 1 (cut-off at 1322 units/l; odds ratio (OR) 24·61, 95 per cent confidence interval 11·55 to 52·42) and POD 2 (cut-off at 314 units/l; OR 35·45, 14·07 to 89·33) was superior to that of PPA on POD 1 (cut-off at 177 units/l; OR 13·67, 6·46 to 28·94) and POD 2 (cut-off at 98 units/l; OR 16·97, 8·33 to 34·59). When DPA was combined with CRP (cut-off on POD 3 at 202 mg/l; OR 16·98, 8·43 to 34·21), 90·3 per cent of postoperative courses could be predicted correctly (OR 44·14, 16·89 to 115·38).ConclusionThe combination of serum CRP and DPA adequately predicted the development of clinically relevant pancreatic fistula following PD.

- Background: Resection with curative intent has been shown to prolong survival of patients with locoregional pancreatic ductal adenocarcinoma (PDAC). However, up to 33 per cent of patients are deemed unresectable at exploratory laparotomy owing to unanticipated locally advanced or metastatic disease. In these patients, prophylactic double bypass (PDB) procedures have been considered the standard of care. The aim of this study was to compare PDB with exploratory laparotomy alone in terms of impact on postoperative course, chemotherapy and overall survival.Methods: This retrospective observational cohort study (2004-2013) was conducted using a prospective institutional database. Patients with histologically confirmed, unresectable PDAC were included. Relationships between PDB procedures, exploratory laparotomy alone, postoperative chemotherapy and best supportive care were investigated by means of Cox regression. Overall survival was compared using Kaplan-Meier estimations and log rank test.Results: Of 503 patients with PDAC scheduled for resection with curative intent, 104 were deemed unresectable at laparotomy (resection rate 79·3 per cent). Seventy-four patients underwent PDB procedures and 30 had exploratory laparotomy alone. PDB and exploratory laparotomy were similar in terms of perioperative mortality, initiation of chemotherapy and overall survival. Compared with best supportive care, postoperative chemotherapy prolonged survival (8·0 versus 14·4 months in locally advanced PDAC, P = 0·007; 2·3 versus 8·0 months in metastatic PDAC, P < 0·001). Patients undergoing chemotherapy following exploratory laparotomy alone had longer median overall survival than patients undergoing chemotherapy following PDB procedures (16·3 versus 10·3 months; P = 0·040).Conclusion: Patients with pancreatic cancer deemed unresectable at laparotomy may derive survival benefit from subsequent chemotherapy as opposed to supportive care alone. At laparotomy, proceeding with a bypass procedure for prophylactic symptom control may be prognostically unfavourable.

- Background: Randomized trials have shown that neoadjuvant treatment improves survival in the curative treatment of oesophageal and gastro-oesophageal junction cancer. Results from population-based observational studies are, however, sparse and ambiguous. Methods: This prospective population-based cohort study included all patients who had oesophagectomy for cancer in Sweden, excluding clinical T1 N0, recorded in the National Register for Oesophageal and Gastric Cancer, 2006–2014. Patients were stratified into three groups: surgery alone, neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy. Results: Neoadjuvant treatment was given to 521 patients (51·1 per cent) and 499 (48·9 per cent) received surgery alone. Neoadjuvant chemotherapy increased the risk of postoperative surgical complications compared with surgery alone (adjusted odds ratio 2·01, 95 per cent c.i. 1·24 to 3·25; P = 0·005). Postoperative mortality was significantly increased after neoadjuvant chemoradiotherapy compared with surgery alone (odds ratio 2·37, 1·06 to 5·29; P = 0·035). Survival improved in patients with squamous cell carcinoma after neoadjuvant chemotherapy, whereas after neoadjuvant chemoradiotherapy survival was significantly improved only in the subgroup with the highest performance status and without known co-morbidity. In adenocarcinoma there was a trend towards improved overall survival after neoadjuvant chemotherapy, but neoadjuvant chemoradiotherapy did not offer a survival benefit. Stratified analysis including only patients with adenocarcinoma in the highest performance category without known co-morbidity showed a strong trend towards improved survival after neoadjuvant chemotherapy compared with surgery alone (adjusted hazard ratio 0·47, 0·21 to 1·04; P = 0·061). Conclusion: For patients with squamous cell carcinoma of the oesophagus or gastro-oesophageal junction, neoadjuvant treatments seemed to increase long-term survival, but also the risk of postoperative morbidity and mortality, compared with surgery alone. Neither neoadjuvant treatment option seemed to improve survival significantly among patients with adenocarcinoma, compared with surgery alone.

Tidskriftsartikel (refereegranskat)abstract
- Background: The Swedish National Register for Oesophageal and Gastric Cancer (NREV) was launched in 2006. Data are reported at diagnosis (diagnostic survey), at the time of surgery (surgical survey) and at first outpatient follow-up (follow-up survey). The aim of this study was to evaluate data originating from NREV in terms of comparability, completeness, accuracy and timeliness. Methods: Coding routines were compared with international standards and completeness was evaluated by means of a 5-year (2009–2013) comparison with mandatory national registers. Validity was tested by comparison with reabstracted data from source medical records in 400 patients chosen randomly with stratification for hospital size and catchment area population. Timeliness of registration was described. Results: Coding routines followed national and international guidelines. Compared with the Swedish Cancer Registry from 2009 to 2013, 6069 (95·5 per cent) of 6354 patients were registered in NREV at the time of data extraction. Of 60 variables investigated, 10 966 of 12 035 original entries were correct in the reabstraction, resulting in an exact agreement of 91·1 per cent in the register. There were 782 (6·5 per cent) incorrect and 287 (2·4 per cent) missing entries. Median time to registration was 3·9, 3·4 and 4·1 months for diagnostic, surgical and follow-up surveys respectively. Conclusion: NREV has reached a position with good coverage of those with the relevant diagnoses, and contains comparable and valid data. Quality data on each variable are available. Timeliness is an area with potential for improvement.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Total fundoplication is the most common antireflux operation and can be performed with or without division of the short gastric vessels. There seems to be no difference in short-term outcomes with either approach. The aim of the study was to determine whether there were the long-term differences (after 10 years). METHODS: Ninety-nine patients were enrolled in the study. Short gastric vessels were divided in 52 patients (group 1) and left intact in 47 (group 2). Ten patients were lost to follow-up and seven patients died, leaving 42 patients for analysis in group 1 and 40 in group 2. All patients were evaluated by standardized quality of life questionnaires. RESULTS: Three patients underwent reoperation within 5 years. Thirty-eight of 42 patients with a completely mobilized fundus reported no reflux symptoms, compared with 31 of 40 patients with intact vessels. There were no differences between the groups in other symptoms reflecting post-fundoplication complaints and quality of life outcomes. CONCLUSION: When total fundoplication is performed it makes no difference whether the fundus is mobilized or not. Both types of repair provide lasting control of reflux.

Tidskriftsartikel (refereegranskat)abstract
- Background: Locoregional pancreatic ductal adenocarcinoma (PDAC) may progress rapidly and/or disseminate despite having an early stage at diagnostic imaging. A prolonged interval from imaging to resection might represent a risk factor for encountering tumour progression at laparotomy. The aim of this study was to determine the therapeutic window for timely surgical intervention.Methods: This observational cohort study included patients with histologically confirmed PDAC scheduled for resection with curative intent from 2008 to 2014. The impact of imaging-to-resection/reassessment (IR) interval, vascular involvement and tumour size on local tumour progression or presence of metastases at reimaging or laparotomy was evaluated using univariable and multivariable regression. Risk estimates were approximated using hazard ratios (HRs).Results: Median IR interval was 42 days. Of 349 patients scheduled for resection, 82 had unresectable disease (resectability rate 76.5 per cent). The unresectability rate was zero when the IR interval was 22 days or shorter, and was lower for an IR interval of 32 days or less compared with longer waiting times (13 versus 26.2 per cent; HR 0.42, P = 0.021). It was also lower for tumours smaller than 30 mm than for larger tumours (13.9 versus 32.5 per cent; HR 0.34, P < 0.001). Tumours with no or minor vascular involvement showed decreased rates of unresectable disease (20.6 per cent versus 38 per cent when there was major or combined vascular involvement; HR 0.43, P = 0.007). However, this failed to reach statistical significance on multivariable analysis (P = 0.411), in contrast to IR interval (P = 0.028) and tumour size (P < 0.001).Conclusion: Operation within 32 days of diagnostic imaging reduced the risk of tumour progression to unresectable disease by half compared with a longer waiting time. The results of this study highlight the importance of efficient clinical PDAC management.
