Obesity surgery

Recently, randomized controlled trials (RCTs) have indicated that bariatric surgery in nonseverely obese patients with a body mass index (BMI) less than 35 kg/m2 might be even superior to medical therapy with regard to type 2 diabetes mellitus (T2DM) remission, but the efficacy of laparoscopic Roux-en-Y gastric bypass (LRYGB) compared with laparoscopic sleeve gastrectomy (LSG) in nonseverely obese patients has not been conclusively determined. The objective of this study is to compare LRYGB versus LSG for T2DM in nonseverely obese patients. ⋯ Both LRYGB and LSG have comparative effect on resolving T2DM in nonseverely obese patients at midterm follow-up. Further RCTs should address the potential risks and long-term effects of LRYGB and LSG in nonseverely obese patients.

Randomized Controlled Trial
Randomized, Double-Blind Study of the Effect of Intraoperative Intravenous Lidocaine on the Opioid Consumption and Criteria for Hospital Discharge After Bariatric Surgery.
Surgical trauma, pain and opioids can cause nausea, vomiting, ileus and increased length of hospital stay. The primary objective of the study was to evaluate the time to recovery of gastrointestinal function and the time to meet hospital discharge criteria after laparoscopic bariatric surgery with intraoperative intravenous lidocaine administration. Secondary objectives were to evaluate morphine consumption during the first 24 h and the side effects of opioids. ⋯ Perioperative intravenous lidocaine is feasible and easily accessible when administered at appropriate doses. Lidocaine reduces morphine consumption.

OAGB-MGB emerged as a standard procedure, albeit RYGB remains the most frequently performed gastric bypass. Comparative studies are scarce. ⋯ TWL, malnutrition, and comorbidity remission 3 years postoperatively were comparable. Gastroesophageal reflux was less frequent after RYGB (p = 0.0729), whereas shorter operation times (p < 0.0001), less frequent stenosis (p < 0.0001), and dumping syndrome (p = 0.0018) were found in OAGB-MGB. Further RCTs are required.

Banded sleeve gastrectomy (BSG), a modification of the laparoscopic sleeve gastrectomy (SG), and one anastomotic gastric bypass/mini-gastric bypass (OAGB/MGB), a modification to the Roux-en-Y gastric bypass (RYGB), have been reported to enhance weight loss and minimize significant weight regain when compared with the SG and RYGB respectively. However, there has not been any report or study comparing these two operations. ⋯ Both operations produced excellent weight loss and maintenance in the short to intermediate term. There was better resolution of T2D and HTN after OAGB/MGB at the expense of a higher incidence of nutrient deficiency and some protein caloric malnutrition. There is need for prospective and larger series studies to confirm these findings.
