The decision to perform intraoperative blood transfusion is subject to a variety of clinical and laboratory factors. This study examined variation in haemoglobin (Hb) triggers and overall utilization of intraoperative blood transfusion, as well the impact of transfusion on perioperative outcomes. ⋯ Use of perioperative blood transfusion varies among surgeons and type of operation. Nearly one in four patients received a blood transfusion with a liberal intraoperative transfusion Hb trigger of 10 g/dl or more. Intraoperative blood transfusion was associated with higher risk of perioperative morbidity.

Comparative Study
Morphometric analysis and lymph node yield in laparoscopic complete mesocolic excision performed by supervised trainees.
Complete mesocolic excision with central vascular ligation (CME) produces an optimal colonic cancer specimen. The ability of expert laparoscopic surgeons to produce equivalent specimens is unknown. ⋯ Laparoscopic CME can be performed to the same standard as open surgery by supervised trainees. However, this did not increase the lymph node yield.

Review Meta Analysis Comparative Study
Meta-analysis and meta-regression analysis of biomarkers for abdominal aortic aneurysm.
Many studies have investigated the systemic and local expression of biomarkers in patients with abdominal aortic aneurysm (AAA). The natural history of AAA varies between patients, and predictors of the presence and diameter of AAA have not been determined consistently. The aim of this study was to perform a systematic review, meta-analysis and meta-regression of studies comparing biomarkers in patients with and without AAA, with the aim of summarizing the association of identified markers with both AAA presence and size. ⋯ A wide variety of biomarkers are dysregulated in patients with AAA, but their clinical value is yet to be established. Future research should focus on the most relevant biomarkers of AAA, and how they could be used clinically.

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.

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).
