The incidence of pancreatic neuroendocrine neoplasms (pNEN) is increasing. This study aimed to evaluate predictors of overall survival and the indication for surgery. ⋯ Neuroendocrine tumours graded G3, lymph node and distant metastasis are independent predictors of worse overall survival in patients with pNEN.

Review Meta Analysis Comparative Study
Meta-analysis of peak wall stress in ruptured, symptomatic and intact abdominal aortic aneurysms.
Abdominal aortic aneurysm (AAA) is an important cause of sudden death; however, there are currently incomplete means to predict the risk of AAA rupture. AAA peak wall stress (PWS) can be estimated using finite element analysis (FEA) methods from computed tomography (CT) scans. The question is whether AAA PWS can predict AAA rupture. The aim of this systematic review was to compare PWS in patients with ruptured and intact AAA. ⋯ This study suggests that PWS is greater in symptomatic or ruptured AAA than in asymptomatic intact AAA.

Review Meta Analysis
Meta-analysis of operative mortality and complications in patients from minority ethnic groups.
Insight into the effects of ethnic disparities on patients' perioperative safety is necessary for the development of tailored improvement strategies. The aim of this study was to review the literature on safety differences between patients from minority ethnic groups and those from the ethnic majority undergoing surgery. ⋯ Patients from minority ethnic groups, in North America and elsewhere, have an increased risk of perioperative death and complications. More insight is needed into the causes of ethnic disparities to pursue safer perioperative care for patients of minority ethnicity.

Randomized Controlled Trial Multicenter Study Comparative Study
Randomized clinical trial comparing self-gripping mesh with suture fixation of lightweight polypropylene mesh in open inguinal hernia repair.
Postoperative pain is an important adverse event following inguinal hernia repair. The aim of this trial was to compare postoperative pain within the first 3 months and 1 year after surgery in patients undergoing open mesh inguinal hernia repair using either a self-gripping lightweight polyester mesh or a polypropylene lightweight mesh fixed with sutures. ⋯ NCT00827944 (http://www.clinicaltrials.gov).

Multicenter Study Observational Study
Incidence of and risk factors for incisional hernia after abdominal surgery.
Few larger studies have estimated the incidence of incisional hernia (IH) after abdominal surgery. ⋯ UMIN000004723 (University Hospital Medical Information Network, http://www.umin.ac.jp/ctr/index.htm).
