- 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.

- BACKGROUND: Contemporary patients with primary hyperparathyroidism are often diagnosed with mildly raised serum calcium levels. Previous studies have reported increased mortality in patients with primary hyperparathyroidism. This retrospective cohort study aimed to examine whether contemporary patients operated for primary hyperparathyroidism have higher mortality than the general population, and whether mortality in these patients is associated with serum calcium concentration, adenoma weight or multiglandular disease. METHODS: Patients from a Swedish national cohort consisting of patients registered in the Scandinavian Quality Register for Thyroid, Parathyroid, and Adrenal Surgery 2003-2013, were matched with population controls. The National Patient Register, the Swedish Cause of Death Register, and socioeconomic data were cross-linked. End of follow-up was 10 years after surgery, 31 December 2015, or emigration. Mortality was analysed by standardized mortality ratio, Kaplan-Meier survival estimates, and univariable and multivariable Cox regression. Multiple imputation by chained equations was performed on missing data. RESULTS: After exclusions, there were 5009 patients with primary hyperparathyroidism and 14 983 controls. Multivariable Cox regression analysis adjusted for age, sex, Charlson Co-morbidity Index, marital status, level of education, disposable income, and period of surgery showed lower mortality in patients than controls (hazard ratio (HR) 0.83, 95 per cent c.i. 0.75 to 0.92). In univariable Cox regression of mortality in patients, serum calcium concentration (mmoles per litre) was associated with mortality (HR 2.20, 1.53 to 3.16). This association remained in multivariable Cox regression after multiple imputation (HR 1.79, 1.19 to 2.70). CONCLUSION: Mortality was not increased in patients operated for primary hyperparathyroidism compared with controls in a contemporary setting. Preoperative serum calcium concentration might, however, influence survival.

- BACKGROUND: Whether intraoperative cholangiography can prevent iatrogenic bile duct injury during cholecystectomy remains controversial.METHODS: Data from the national Swedish Registry for Gallstone Surgery, GallRiks (May 2005 to December 2010), were analysed for evidence of iatrogenic bile duct injury during cholecystectomy. Patient- and procedure-related risk factors for bile duct injury with a focus on the rate of intended intraoperative cholangiography were analysed using multivariable logistic regression.RESULTS: A total of 51 041 cholecystectomies and 747 bile duct injuries (1·5 per cent) were identified; 9008 patients (17·6 per cent) were diagnosed with acute cholecystitis. No preventive effect of intraoperative cholangiography was seen in uncomplicated gallstone disease (odds ratio (OR) 0·97, 95 per cent c.i. 0·74 to 1·25). Operating in the presence (OR 1·23, 1·03 to 1·47) or a history (OR 1·34, 1·10 to 1·64) of acute cholecystitis, and open surgery (OR 1·56, 1·26 to 1·94), were identified as significant risk factors for bile duct injury. The intention to perform intraoperative cholangiography was associated with a reduced risk of bile duct injury in patients with concurrent (OR 0·44, 0·30 to 0·63) or a history of (OR 0·59, 0·35 to 1·00) acute cholecystitis.CONCLUSION: Any proposed protective effect of intraoperative cholangiography was restricted to patients with (or a history of) acute cholecystitis.
