Summary: This study aimed to compare the use of opioids in patients with obesity who underwent bariatric surgery versus those who underwent intensive lifestyle modification. The results showed that patients who underwent bariatric surgery had a higher proportion of opioid users and a larger total opioid dose, especially in those who received additional surgery during follow-up.

Summary: Obesity is a critical risk factor for life-threatening diseases, and the prevalence in adults has significantly increased in the past decade. Surgical treatment, such as sleeve gastrectomy, is the most effective method for obese patients. However, the changes in gastric wall cells and pacemaker activity after surgery, as well as the recovery of normal gastric activity, require further investigation.

Summary: Among patients with severe obesity undergoing SG and RYGB, significantly more weight loss was observed at 5 years compared to nonsurgical patients. Weight regain was common after surgery, but regain to within 5% of baseline was rare.

Summary: Sleeve gastrectomy is the most common weight loss surgery for severe obesity, but complications like leakages and strictures can occur. Gastric twist is a rare complication, which is a functional obstruction of the gastric remnant likely caused by technical mistakes. Endoscopy is the first choice for diagnosis and treatment, but surgery is necessary if endoscopy fails.

Summary: Obesity is a worldwide epidemic with adverse health effects, leading to increased use of bariatric surgery such as sleeve gastrectomy (SG) and Roux-en-Y-gastric bypass (RYGB). This review focuses on postoperative osteoporosis risk and micronutrient deficiencies associated with RYGB and SG. Dietary habits in obese individuals may contribute to deficiencies in vitamin D and other nutrients affecting bone metabolism. Both surgical procedures have different impacts on nutrient absorption, with SG affecting vitamin B-12 and D absorption, while RYGB affects fat-soluble vitamins. Regular follow-ups and nutritional advice are crucial to prevent osteoporosis and other postoperative issues.

Summary: In a large cohort of commercially insured patients, sleeve gastrectomy was found to have a superior safety profile to gastric bypass up to 2 years from surgery, even when accounting for selection bias. However, further exploration is needed regarding the higher risk of revisions in sleeve gastrectomy.

Summary: Revisional surgery to convert sleeve gastrectomy (SG) to either Roux-en-Y gastric bypass (RYGB) or duodenal switch (DS) can lead to significant and sustained weight loss in the first 12 months. There was no significant difference in excess body weight loss between RYGB and DS patients at 6, 12, and 24 months, except for greater weight loss in RYGB patients at 3 months. Procedure length was significantly longer for DS compared to RYGB, with no significant differences in length of stay and 30-day readmission rates.

Summary: This study compared the long-term outcomes of one anastomosis gastric bypass (OAGB) and sleeve gastrectomy (SG) in bariatric surgery patients. The results showed that OAGB had superior effects on weight loss, improvement of type 2 diabetes and sleep apnea, while SG was associated with more long-term problems such as insufficient weight loss/regain and reflux. However, OAGB had a higher risk of nutritional deficiencies.

Summary: This study assessed the relevance of concomitant laparoscopic metabolic bariatric surgery (MBS) and cholecystectomy, and found that cholecystectomy should be avoided during sleeve gastrectomy (SG) and gastric bypass (GBP) procedures. Prophylactic cholecystectomy is not recommended for asymptomatic gallstones after MBS.

Summary: This study evaluated the incidence of marginal ulcers (MUs) after primary and secondary Roux-en-Y Gastric Bypass (RYGB). The results showed that patients who underwent conversion of Sleeve Gastrectomy to RYGB had a higher incidence of MUs compared to those who had primary RYGB or Gastric Banding to RYGB. Furthermore, the time to MU development was significantly shorter in patients who underwent conversion surgery.

Summary: The most common indication for revisional surgery after sleeve gastrectomy is weight loss failure. Options for revisional surgery include RYGB, OAGB, and re-sleeve, but there are higher complication rates following revisional surgery. The efficacy of re-operation in terms of weight loss and morbidity reduction is still debated due to the lack of high-quality evidence in the field.

Summary: Sleeve gastrectomy is a commonly performed bariatric surgery, with rising prevalence of gastric sleeve stenosis (GSS). Management with pneumatic dilation is successful but underused due to lack of diagnostic criteria. This study aimed to develop quantifiable endoscopic criteria for GSS diagnosis, finding an association between narrowest to widest gastric lumen diameter ratio and presence of bilious fluid with EndoFLIP and gastric lumen morphology diagnosis. Further studies are needed to validate these criteria.

Summary: This study compared the safety and efficacy of sleeve gastrectomy (SG) and one anastomosis gastric bypass (OAGB) as conversion surgical procedures for patients who had adjustable gastric band (LAGB) and experienced suboptimal response or weight recurrence. The results showed that both procedures resulted in significant weight loss and similar remission of comorbidities, but OAGB had a higher complication rate compared to SG.

Summary: The study showed that patients with type 2 diabetes undergoing Roux-en-Y gastric bypass (RYGB) surgery experienced significant reductions in body weight, fat mass, fasting glucose and insulin levels, and circulating lipids 2 weeks post-operation. Oral feeding enhanced insulin and incretin secretion after RYGB, while G-tube feeding completely abolished this enhancement, suggesting that foregut exclusion plays a role in improving glucose metabolism after RYGB, but may not be the sole explanation.

Summary: Improvement of glucose levels in people with diabetes can occur spontaneously or after medical interventions. Newer forms of treatment may lead to more sustained improvement. However, the terminology and objective measures for defining this process are not established, and the long-term risks and benefits are not well understood. An international expert group proposed the term "remission" and HbA1c < 6.5% as the usual diagnostic criterion. They also suggested active observation and further research on predictors and outcomes of remission.

Summary: This study examines student perceptions of preparedness for the operating room, resource usage, and time spent on preparation. The results indicate that students feel adequately prepared for discussing operative indications, contraindications, anatomy, and complications but less prepared for operative steps. The average preparation time per case was 28 minutes, with UpToDate and online videos being the most commonly used resources. The use of an anatomic atlas was weakly correlated with improved preparedness for discussing relevant anatomy. Other resources, time spent, or number of resources used were not associated with increased preparedness. The findings suggest a need for improved student-oriented preparatory materials that take into account students' preferences for technology-based resources and time constraints.

Summary: This systematic review and meta-analysis found that the incidence of new-onset gastroesophageal reflux after one-anastomosis gastric bypass (OAGB) was 6%. There was no significant change in the preoperative reflux status after OAGB. The rates of esophagitis and Barrett's esophagus were 15% and 1% respectively. The rate of new-onset reflux after OAGB was higher than gastric bypass but not different from sleeve gastrectomy.
