Discrimination between simple and perforated appendicitis in patients with suspected appendicitis may help to determine the therapy, timing of surgery and risk of complications. The aim of this study was to estimate the accuracy of magnetic resonance imaging (MRI) in distinguishing between simple and perforated appendicitis, and to compare MRI against ultrasound imaging with selected additional (conditional) use of computed tomography (CT).

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is an effective treatment for morbid obesity, but might aggravate gastrointestinal complaints and food intolerance. The long-term prevalence of these symptoms has not been well studied.

Recent reviews suggest that the way in which surgeons prepare for a procedure (warm up) can affect performance. Operating lists present a natural experiment to explore this phenomenon. The aim was to use a routinely collected large data set on surgical procedures to understand the relationship between case list order and operative performance.

Endoscopic submucosal dissection is gaining popularity in the treatment of early gastric cancer. This study aimed to identify clinicopathological factors predictive of lymph node metastasis in patients with the poorly differentiated early gastric cancer to assess the feasibility of using endoscopic submucosal dissection for these cancers.

Selection criteria for surgical training are not scientifically proven. There is a need to define which attributes predict future surgical performance. The aim of this study was to examine the predictive value of specific attributes that impact on surgical performance.

A systematic review and network meta-analysis was undertaken to consider the evidence for the efficacy and tolerability of placebo, cilostazol, naftidrofuryl oxalate and pentoxifylline in patients with intermittent claudication due to peripheral arterial disease (PAD).

Self-expanding metallic stents (SEMS) may be used in acute obstructing left-sided colonic cancers to avoid high-risk emergency surgery. However, oncological safety remains uncertain. This study evaluated the long-term oncological outcome of SEMS as a bridge to elective curative surgery versus emergency resection.

The extent of lymphadenectomy in the treatment of gastric cancer has been debated for more than two decades. This meta-analysis sought to evaluate the effectiveness and safety of extended lymphadenectomy in patients with gastric cancer.

Postoperative wound complications are common following surgical procedures. Negative-pressure wound therapy (NPWT) is well recognized for the management of open wounds and has been applied recently to closed surgical incisions. The evidence base to support this intervention is limited. The aim of this study was to assess whether NPWT reduces postoperative wound complications when applied to closed surgical incisions.

Seroma formation, the most prevalent postoperative complication after mastectomy, is an inflammatory process that is potentially preventable via local steroid administration. This study investigated the effect of local steroid administration on seroma formation.
