Review Meta Analysis
Meta-analysis of the influence of surgical margin and adjuvant radiotherapy on local recurrence after resection of sporadic desmoid-type fibromatosis.
Extra-abdominal desmoid-type fibromatosis (DF) is a rare, locally aggressive neoplasm that is usually managed conservatively. When treatment is indicated, it typically involves surgical resection, possibly with adjuvant radiotherapy. The indications for postoperative radiotherapy and its effectiveness are unclear. The objective of this study was to estimate the effect of surgical resection margins and adjuvant radiotherapy on rates of recurrence of DF. ⋯ DF resected with microscopically positive margins has a higher risk of recurrence. Adjuvant radiotherapy appears to reduce the risk of recurrence after incomplete surgical resection, particularly in patients with recurrent tumours.

Review Meta Analysis
Immunohistochemical hENT1 expression as a prognostic biomarker in patients with resected pancreatic ductal adenocarcinoma undergoing adjuvant gemcitabine-based chemotherapy.
Human equilibrative nucleoside transporters (hENTs) are transmembranous proteins that facilitate the uptake of nucleosides and nucleoside analogues, such as gemcitabine, into the cell. The abundance of hENT1 transporters in resected pancreatic ductal adenocarcinoma (PDAC) might make hENT1 a potential biomarker of response to adjuvant chemotherapy. The aim of this study was to see whether hENT1 expression, as determined by immunohistochemistry, was a suitable predictive marker for subsequent treatment with gemcitabine-based adjuvant chemotherapy. ⋯ Expression of hENT1 is a suitable prognostic biomarker in patients undergoing adjuvant gemcitabine-based chemotherapy.

Randomized Controlled Trial Multicenter Study
Randomized clinical trial of preoperative dexamethasone on postoperative nausea and vomiting after laparoscopy for suspected appendicitis.
Few studies have investigated the effects of preoperative dexamethasone in acute surgical patients. This study examined the effects of 8 mg dexamethasone administered intravenously 30 min before surgery for suspected acute appendicitis. ⋯ Preoperative dexamethasone did not reduce PONV by the target level of 50 per cent. Registration number: NCT02415335 ( http://www.clinicaltrials.gov).

Returning to the operating theatre for management of early postoperative complications after colorectal surgery is an important key performance indicator. Laparoscopic surgery has benefits that may be useful in surgical emergencies. This study explored the evidence for the advantages of laparoscopic reoperation. ⋯ Laparoscopic reoperation is feasible in selected patients, with the advantages of improved short-term outcomes.

Multicenter Study Comparative Study
Three-point transfusion risk score in hepatectomy.
Perioperative red blood cell transfusions are required in up to 23 per cent of patients undergoing hepatectomy. Previous research has developed three transfusion risk scores to assess risk of perioperative red blood cell transfusion. Here, the performance of these transfusion risk scores was evaluated in a multicentre cohort of patients who underwent hepatectomy and compared with that of a simplified transfusion risk score. ⋯ The three-point transfusion risk score simplifies assessment of perioperative transfusion risk in hepatectomy without sacrificing predictive ability.
