- In this nationwide Swedish study, later weekday of esophageal cancer surgery entailed increased long-term mortality, particularly for earlier tumor stages. The increase in 5-year mortality for each later weekday was 7% for all tumor stages, 24% for stages 0-I, 13% for stage II, but was not increased for stages III-IV. Objective: To assess whether weekday of surgery influences long-term survival in esophageal cancer. Summary Background Data: Increased 30-day mortality rates have been reported in patients undergoing elective surgery later compared to earlier in the week Methods: This population-based cohort study included 98% of all esophageal cancer patients who underwent elective surgery in Sweden in 1987-2010, with follow-up until 2014. The association between weekday of surgery and 5-year all-cause and disease-specific mortality was analyzed using a multivariable Cox proportional hazards model, providing hazard ratios (HRs) with 95% confidence intervals (CIs), adjusted for age, co-morbidity, tumor stage, histology, neoadjuvant therapy, and surgeon volume. Results: Among 1,748 included patients, surgery conducted Wednesday-Friday entailed 13% increased all-cause 5-year mortality compared to surgery Monday-Tuesday (HR=1.13, 95% CI 1.01-1.26). The corresponding association was strong for early tumor stages (0-I) (HR=1.59, 95% CI 1.17-2.16), moderate for intermediate tumor stage (II) (HR=1.28, 95% CI 1.07-1.53), and absent in advanced tumor stages (III-IV) (HR=0.93, 95%CI 0.79-1.09). The increase in 5-year mortality for each later weekday (discrete variable) was 7% for all tumor stages (HR=1.07, 95% CI 1.02-1.12), 24% for early tumor stages (HR=1.24, 95% CI 1.09-1.41), 13% for intermediate stage (HR=1.13, 95% CI 1.05-1.22), while no increase was found for advanced stages (HR=0.98, 95% CI 0.92-1.05). The disease-specific 5-year mortality was similar to the all-cause mortality. Conclusions: The increased 5-year mortality of potentially curable esophageal cancer following surgery later in the week suggests that this surgery is better performed earlier in the week.

- Objective: To investigate the preventive effect of antireflux surgery against esophageal adenocarcinoma (EAC), compared to medical treatment of gastroesophageal reflux disease (GERD) and to the background population. Background: GERD is causally associated with EAC. Effective symptomatic treatment can be achieved with medication and antireflux surgery, yet the possible preventive effect on EAC development remains unclear. Methods: This systematic review identified 10 studies comparing EAC risk following antireflux surgery with non-operated GERD patients, including 7 studies of patients with Barrett’s esophagus; and 2 studies comparing EAC risk after antireflux surgery to the background population. A fixed-effects Poisson meta-analysis was conducted to calculate pooled incidence rate ratios (IRR) and 95% confidence intervals (CI). Results: The pooled IRR in patients following antireflux surgery was 0.76 (95% CI 0.42-1.39) compared to medically treated GERD patients. In patients with Barrett’s esophagus, the corresponding IRR was 0.46 (95% CI 0.20-1.08), and 0.26 (95% CI 0.09-0.79) when restricted to publications after 2000. There was no difference in EAC risk between antireflux surgery and medical treatment in GERD patients without known Barrett’s esophagus (IRR 0.98, 95% CI 0.72-1.33). The EAC risk remained elevated in patients following antireflux surgery compared to the background population (IRR 10.78, 95% CI 8.48-13.71). While the clinical heterogeneity of the included studies was high, the statistical heterogeneity was low. Conclusions: Antireflux surgery may prevent EAC better than medical therapy in patients with Barrett’s esophagus. The EAC risk following antireflux surgery does not seem to revert to that of the background population.

- Objective: To define benchmark cutoffs for redo liver transplantation (redo-LT). Background: In the era of organ shortage, redo-LT is frequently discussed in terms of expected poor outcome and wasteful resources. However, there is a lack of benchmark data to reliably evaluate outcomes after redo-LT. Methods: We collected data on redo-LT between January 2010 and December 2018 from 22 high-volume transplant centers. Benchmark cases were defined as recipients with model of end stage liver disease (MELD) score <= 25, absence of portal vein thrombosis, no mechanical ventilation at the time of surgery, receiving a graft from a donor after brain death. Also, high-urgent priority and early redo-LT including those for primary nonfunction (PNF) or hepatic artery thrombosis were excluded. Benchmark cutoffs were derived from the 75th percentile of the medians of all benchmark centers. Results: Of 1110 redo-LT, 373 (34%) cases qualified as benchmark cases. Among these cases, the rate of postoperative complications until discharge was 76%, and increased up to 87% at 1-year, respectively. One-year overall survival rate was excellent with 90%. Benchmark cutoffs included Comprehensive Complication Index CCI (R) at 1-year of <= 72, and in-hospital and 1-year mortality rates of <= 13% and <= 15%, respectively. In contrast, patients who received a redo-LT for PNF showed worse outcomes with some values dramatically outside the redoLT benchmarks. Conclusion: This study shows that redo-LT achieves good outcome when looking at benchmark scenarios. However, this figure changes in high-risk redo-LT, as for example in PNF. This analysis objectifies for the first-time results and efforts for redo-LT and can serve as a basis for discussion about the use of scarce resources.

- OBJECTIVE: To ascertain whether regular β-blocker exposure can improve short- and long-term outcomes after rectal cancer surgery.BACKGROUND: Surgery for rectal cancer is associated with substantial morbidity and mortality. There is increasing evidence to suggest that there is a survival benefit in patients exposed to β-blockers undergoing non-cardiac surgery. Studies investigating the effects on outcomes in patients subjected to surgery for rectal cancer are lacking.METHODS: All adult patients undergoing elective abdominal resection for rectal cancer over a 10-year period were recruited from the prospectively collected Swedish Colorectal Cancer Registry. Patients were subdivided according to preoperative β-blocker exposure status. Outcomes of interest were 30-day complications, 30-day cause-specific mortality, and 1-year all-cause mortality. The association between β-blocker use and outcomes were analyzed using Poisson regression model with robust standard errors for 30-day complications and cause-specific mortality. One-year survival was assessed using Cox proportional hazards regression model.RESULTS: A total of 11,966 patients were included in the current study, of whom 3513 (29.36%) were exposed to regular preoperative β-blockers. A significant decrease in 30-day mortality was detected (incidence rate ratio = 0.06, 95% confidence interval: 0.03-0.13, P < 0.001). Deaths of cardiovascular nature, respiratory origin, sepsis, and multiorgan failure were significantly lower in β-blocker users, as were the incidences in postoperative infection and anastomotic failure. The β-blocker positive group had significantly better survival up to 1 year postoperatively with a risk reduction of 57% (hazard ratio = 0.43, 95% confidence interval: 0.37-0.52, P < 0.001).CONCLUSIONS: Preoperative β-blocker use is strongly associated with improved survival and morbidity after abdominal resection for rectal cancer.

- OBJECTIVE: A systematic review of the nonsurgical treatment of patients with appendiceal abscess or phlegmon, with emphasis on the success rate, need for drainage of abscesses, risk of undetected serious disease, and need for interval appendectomy to prevent recurrence. SUMMARY BACKGROUND DATA: Patients with appendiceal abscess or phlegmon are traditionally managed by nonsurgical treatment and interval appendectomy. This practice is controversial with proponents of immediate surgery and others questioning the need for interval appendectomy. METHODS: A Medline search identified 61 studies published between January 1964 and December 2005 reporting on the results of nonsurgical treatment of appendiceal abscess or phlegmon. The results were pooled taking the potential clustering on the study-level into account. A meta-analysis of the morbidity after immediate surgery compared with that after nonsurgical treatment was performed. RESULTS: Appendiceal abscess or phlegmon is found in 3.8% (95% confidence interval (CI), 2.6-4.9) of patients with appendicitis. Nonsurgical treatment fails in 7.2% (CI: 4.0-10.5). The need for drainage of an abscess is 19.7% (CI: 11.0-28.3). Immediate surgery is associated with a higher morbidity compared with nonsurgical treatment (odds ratio, 3.3, CI: 1.9-5.6, P < 0.001). After successful nonsurgical treatment, a malignant disease is detected in 1.2% (CI: 0.6-1.7) and an important benign disease in 0.7% (CI: 0.2-11.9) during follow-up. The risk of recurrence is 7.4% (CI: 3.7-11.1). CONCLUSIONS: The results of this review of mainly retrospective studies support the practice of nonsurgical treatment without interval appendectomy in patients with appendiceal abscess or phlegmon. © 2007 Lippincott Williams & Wilkins, Inc.

- Objective:To evaluate short-term outcomes of a new treatment for perforated diverticulitis with purulent peritonitis in a randomized controlled trial.Background:Perforated diverticulitis with purulent peritonitis (Hinchey III) has traditionally been treated with surgery including colon resection and stoma (Hartmann procedure) with considerable postoperative morbidity and mortality. Laparoscopic lavage has been suggested as a less invasive surgical treatment.Methods:Laparoscopic lavage was compared with colon resection and stoma in a randomized controlled multicenter trial, DILALA (ISRCTN82208287). Initial diagnostic laparoscopy showing Hinchey III was followed by randomization. Clinical data was collected up to 12 weeks postoperatively.Results: Eighty-three patients were randomized, out of whom 39 patients in laparoscopic lavage and 36 patients in the Hartmann procedure groups were available for analysis. Morbidity and mortality after laparoscopic lavage did not differ when compared with the Hartmann procedure. Laparoscopic lavage resulted in shorter operating time, shorter time in the recovery unit, and shorter hospital stay.Conclusions:In this trial, laparoscopic lavage as treatment for patients with perforated diverticulitis Hinchey III was feasible and safe in the short-term.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To investigate the prevalence and risk factors for permanent hypoparathyroidism after total thyroidectomy for benign disease in a population-based setting with data independent of input of complication data.SUMMARY OF BACKGROUND DATA: The reported rate of permanent hypoparathyroidism is highly variable and mostly rely on reported complication data from national or institutional registries.METHODS: All patients who underwent total thyroidectomy in Sweden from 2005 to 2015 were identified through Scandinavian Quality Register for Thyroid, Parathyroid and Adrenal Surgery and the Swedish National Patient Register. Patients were matched to outcome data from the Swedish Prescribed Drug Register. Permanent hypoparathyroidism was defined as treatment with calcium and/or active vitamin D more than 1 year after surgery.RESULTS: Seven thousand eight hundred fifty-two patients were included and 938 (12.5%) developed permanent hypoparathyroidism. The risk was lower in patients registered in the quality register (11.0% vs 16%, P < 0.001). In a multivariable analysis there was a higher risk of permanent hypoparathyroidism in patients with parathyroid autotransplantation [Odds ratio (OR) 1.72; 95% confidence interval 1.47-2.01], center-volume <100 thyroidectomies per year (OR 1.22; 1.03-1.44), age above 60 year (OR 1.64; 1.36-1.98) and female sex (OR 1.27; 1.05-1.54). Reported data from the quality register only identified 178 of all 938 patients with permanent hypoparathyroidism.CONCLUSION: The risk of permanent hypoparathyroidism after total thyroidectomy was high and associated with parathyroid autotransplantation, higher age, female sex and surgery at a low volume center. Reported follow-up data might underestimate the rate of permanent hypoparathyroidism.
