Clinical Trial
Visual Liver Score to Stratify Non-Alcoholic Steatohepatitis Risk and Determine Selective Intraoperative Liver Biopsy in Obesity.
Non-alcoholic fatty liver disease (NAFLD) and its progressive form, non-alcoholic steatohepatitis (NASH), are endemic in obesity. We aimed to evaluate the diagnostic accuracy and reproducibility of a simple intraoperative visual liver score to stratify the risk of NASH and NAFLD in obesity and determine the need for liver biopsy. ⋯ A simple, structured tool based on liver appearance can be a useful and reliable tool for NAFLD risk stratification and identification of patients who would most and least benefit from a biopsy. A normal liver appearance reliably excludes significant liver disease, avoiding the need for liver biopsy in patients otherwise at high clinical risk of NASH.

An increasing number of surgeons worldwide are now performing one anastomosis/mini gastric bypass (OAGB/MGB). Lack of a published consensus amongst experts may be hindering progress and affecting outcomes. This paper reports results from the first modified Delphi consensus building exercise on this procedure. ⋯ OAGB/MGB experts achieved consensus on a number of aspects concerning this procedure but several areas of disagreements persist emphasising the need for more studies in the future.

Randomized Controlled Trial Multicenter Study
Health-Related Quality-of-Life after Laparoscopic Gastric Bypass Surgery with or Without Closure of the Mesenteric Defects: a Post-hoc Analysis of Data from a Randomized Clinical Trial.
Mesenteric defect closure in laparoscopic gastric bypass surgery has been reported to reduce the risk for small bowel obstruction. Little is known, however, about the effect of mesenteric defect closure on patient-reported outcome. The aim of the present study was to see if mesenteric defect closure affects health-related quality-of-life (HRQoL) after laparoscopic gastric bypass. ⋯ When comparing mesenteric defect closure with non-closure, there is no clinically relevant difference in HRQoL after laparoscopic gastric bypass surgery.

Randomized Controlled Trial
A Randomized Comparison Between Staple-Line Oversewing Versus No Reinforcement During Laparoscopic Vertical Sleeve Gastrectomy.
Varieties of intraoperative methods such as oversewing of staple lines or other reinforcement products are used for preventing the laparoscopic vertical sleeve gastrectomy (LSG) complications. The aim of this study is to evaluate the complication rates of the gastric stapling alone versus stapling with oversewing invagination of the staple line in the LSG. ⋯ Oversewing of the staple line during LSG is a nonexpansive and easy method to decrease the incidence and severity of the postoperative bleeding. However, it is time-consuming and should be performed by experienced surgeons to avoid the complications which may occur secondary to the seroserotomy suturing.

Postoperative nausea and vomiting (PONV) is common with bariatric surgery. We examined the PONV rate in bariatric surgical patients who received triple antiemetic prophylaxis (dexamethasone, droperidol, and ondansetron) with and without antiemetic aprepitant. ⋯ Addition of aprepitant to a multimodal antiemetic prophylactic regimen may be associated with significant reduction of PONV during early recovery and potentially with reduced incidence of vomiting during the first 48 postoperative hours. The high PONV rate in the first 48 postoperative hours is suggestive that introduction of scheduled anti-PONV prophylactic treatment may be desirable.
