Summary: The study compared meal-stimulated hormonal responses in patients with postbariatric surgery hypoglycemia (PBH) after sleeve gastrectomy (SG) and after Roux-en-Y gastric bypass (RYGB). The results showed significant differences in glucagon and GLP-1 responses between the two groups, while insulin and GIP responses were similar.

Summary: This article presents a case study of a 27-year-old Asian female patient who underwent a revisional bariatric surgery after poor response to the primary surgery. The laparoscopic procedure successfully controlled her weight and achieved remission of diabetes without any complications.

Summary: This study investigated the effect of weight loss surgery on insulin kinetics. The results showed that the altered insulin clearance rate after surgery is mainly attributed to the liver rather than other organs. In addition, the endogenous insulin clearance rate is more sensitive to the increase in circulating insulin levels, while peripheral insulin sensitivity is similar among the three groups. After a meal, the weight loss surgery group had higher insulin secretion, independent of glycemic levels. Compared to sleeve gastrectomy, gastric bypass surgery resulted in greater post-meal insulin secretion and a reduction in post-meal insulin clearance rate.

Summary: Roux-en Y gastric bypass surgery and sleeve gastrectomy alter postprandial glucose metabolism, increasing the risk of hypoglycemia. After surgery, there is a reduced hepatic glucose production response during insulin-induced hypoglycemia. However, the counterregulatory response to hypoglycemia is similar among individuals with surgery and without surgery.

Summary: The study investigated glucose metabolism and incretin hormone response post-DG in low BMI patients with gastric cancer and type 2 diabetes. BII reconstruction achieved better diabetes control with increased GLP-1 secretion and reduced hyperglucagonemia and GIP compared to BI or RY reconstruction at 6 months postoperatively.

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: 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 nutritional deficiencies and metabolic markers one year after OAGB and SG procedures. The results showed a higher risk of nutritional deficiencies after OAGB, but this risk can be minimized with nutritional recommendations and supplement plans, resulting in comparable metabolic improvement to SG after one year.

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: Sleeve gastrectomy with jejunal bypass (SGJB) is a bariatric/metabolic procedure that delivers food directly to the hindgut to increase the secretion of incretins. This procedure is simple, effective, and has gained popularity and research attention worldwide.

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: The study compared the incidence of GERD, esophagitis, and BE postoperatively in patients undergoing VSG and RYGB, finding that VSG patients had a higher frequency of postoperative GERD, while BE was more prevalent among RYGB patients. De novo esophageal reflux symptomatology was more common in VSG patients, but RYGB patients had a higher rate of re-admission.

Summary: In patients with severe obesity, those undergoing OAGB surgery showed a greater improvement in lipid profile compared to LSG patients. The reduction in plasma lipid levels was independent of the significant decrease in BMI after surgery.

Summary: Morbid obesity is a chronic disease with a rising incidence, and surgical treatment has shown superior outcomes compared to conventional weight loss measures. This study evaluated the long-term weight loss outcomes, comorbidity reduction, and adverse effects of Roux-en-Y Gastric Bypass (RYGB), Biliopancreatic Diversion (BPD), and Sleeve Gastrectomy (SG) at 10 years. RYGB and BPD resulted in significant weight loss, with no observed differences in diabetes resolution and adverse outcomes. Longer follow-up reports are important for comparing the outcomes of different bariatric operations.

Summary: Among patients with BMI >= 50 kg/m(2), biliopancreatic diversion with duodenal switch (BPD/DS) was the most effective operation in long-term reduction of BMI, achieving the highest total weight loss, but was associated with higher rates of early and late surgical complications compared to Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) at 60 months post-op.

Summary: Intestinal FGF15 plays a crucial role in weight control, bone protection, and glucose tolerance after vertical sleeve gastrectomy (VSG). Knockout of FGF15 in mice leads to more adverse effects during VSG, indicating the importance of FGF15 in post-surgery outcomes.

Summary: Gastric bypass and vertical sleeve gastrectomy (VSG) are effective treatments for obesity and type 2 diabetes, but they are also associated with iron deficiency. Increasing iron levels does not undermine the effects of VSG, and gut-specific deletion of Vhl mimics the effects of VSG and increases the secretion of GLP-1.

Summary: This study found that both diets high in fermentable fiber and vertical sleeve gastrectomy increase the expression and circulation of the anti-microbial peptide Reg3g in the intestines. Moreover, the beneficial effects of these interventions on gut function, energy balance, and glucose regulation are not present in mice lacking Reg3g. Peripheral administration of various preparations of Reg3g improves glucose tolerance, and this effect depends on the putative receptor Extl3 in the pancreas.
