Multicenter Study Comparative Study
Comparison of two prognostic models in trauma outcome.
The Trauma Audit and Research Network (TARN) in the UK publicly reports hospital performance in the management of trauma. The TARN risk adjustment model uses a fractional polynomial transformation of the Injury Severity Score (ISS) as the measure of anatomical injury severity. The Trauma Mortality Prediction Model (TMPM) is an alternative to ISS; this study compared the anatomical injury components of the TARN model with the TMPM. ⋯ TMPM had greater discrimination, proximity to the true model and goodness-of-fit than the anatomical injury component of TARN. TMPM should be considered for the injury severity measure for the comparative assessment of trauma centres.

Multicenter Study
Intrathoracic versus cervical anastomosis and predictors of anastomotic leakage after oesophagectomy for cancer.
Studies comparing the anastomotic leak rate in patients with an intrathoracic versus a cervical anastomosis after oesophagectomy are equivocal. The aim of this study was to compare clinical outcome after oesophagectomy in patients with an intrathoracic or cervical anastomosis, and to identify predictors of anastomotic leakage in a nationwide audit. ⋯ An intrathoracic oesophagogastric anastomosis was associated with a lower anastomotic leak rate, lower rate of recurrent nerve paresis and a shorter hospital stay. Risk factors for anastomotic leak were co-morbidities and proximal tumours.

Multicenter Study Comparative Study
Propensity score-matched comparison of oncological outcomes between laparoscopic and open distal pancreatic resection.
Selected studies have reported improved outcomes in laparoscopic compared with open distal pancreatic resection. Concerns regarding failure to achieve proper oncological resection and compromised long-term outcomes remain. This study investigated whether postoperative outcomes and long-term survival after laparoscopic distal pancreatectomy are comparable to those after an open procedure. ⋯ Laparoscopic distal pancreatectomy is an acceptable alternative to open distal pancreatectomy with no detriment to survival.

Multicenter Study
Multicentre study evaluating the surgical learning curve for posterior retroperitoneoscopic adrenalectomy.
Posterior retroperitoneoscopic adrenalectomy has gained international popularity in the past decade. Despite major advantages, including shorter duration of operation, minimal blood loss and decreased postoperative pain, many surgeons still prefer laparoscopic transperitoneal adrenalectomy. It is likely that the unfamiliar anatomical environment, smaller working space and long learning curve impede implementation. The present study assessed the number of procedures required to fulfil the surgical learning curve for posterior retroperitoneoscopic adrenalectomy. ⋯ In specialized endocrine surgical centres between 24 and 42 procedures are required to fulfil the entire surgical learning curve for the posterior retroperitoneoscopic adrenalectomy.

Gastric leak is the most feared surgical postoperative complication after sleeve gastrectomy. An endoscopic procedure is usually required to treat the leak. No data are available on the cost-effectiveness of different stent types in this procedure. ⋯ DPS for the treatment of gastric leak is more cost-effective than CS and should be proposed as the standard regimen whenever possible.
