Obesity Surgery

Abstract Background High intra-abdominal pressure (IAP) during bariatric surgery may compromise cerebral perfusion. This study evaluates the impact of 12 vs. 16 mmHg pneumoperitoneum on internal carotid artery (ICA) hemodynamics and cerebral oxygenation (rSO 2 ) in patients with severe obesity undergoing laparoscopic sleeve gastrectomy (LSG). Methods In this prospective, randomized, double-blind …

Abstract Introduction Telemedicine provides outcomes comparable to in-person follow-up after Metabolic Bariatric Surgery (MBS), but evidence on multicomponent online interventions in the late postoperative period remains scarce. This study evaluated the effects of a supervised online multicomponent program on sarcopenia risk and related components in adults 2–7 years after MBS. Methods In this ra…

Abstract Introduction Choledocholithiasis is challenging to treat in patients who have undergone Roux-en-Y gastric bypass (RYGB). Laparoscopic transcystic common bile duct exploration (LTCBDE) performed at the time of the cholecystectomy is an alternative treatment modality that has the potential to reduce hospital length of stay (LOS) and postoperative morbidity. Methods This is an IRB-approved,…

Abstract Background Roux-en-Y gastric bypass (RYGB) effectively leads to weight loss in patients with severe obesity but is often accompanied by refractory iron deficiency. The molecular mechanisms governing the human intestinal copper-iron metabolic axis post-surgery remain poorly defined. This study evaluated the longitudinal impact of RYGB on intestinal gene expression related to micronutrient…

Abstract Background Transversus abdominis plane (TAP) block is commonly used as an element of multimodal analgesia following abdominal surgery; however, its efficacy in Roux-en-Y gastric bypass (RYGB) remains uncertain. Aim To perform a systematic review and meta-analysis of randomised clinical trials (RCTs) to evaluate the effectiveness of TAP block following RYGB. Methods A comprehensive search…

NCT04548232.

Bilio-pancreatic diversion (BPD), once a prominent bariatric procedure, has seen a marked decline in use due to high rates of nutritional deficiencies and frequent need for surgical revisions. Despite this, BPD remains in practice in select centers, leading to a persistent cohort of patients requiring revisional surgery. We conducted a retrospective review at a high-volume bariatric surgery cente…

Abstract Background Sleeve gastrectomy (SG) is the most frequently performed metabolic and bariatric surgery (MBS) worldwide, but long-term suboptimal weight loss (SOWL) or recurrent weight gain (RWG) affects up to one third of patients and often necessitates revisional procedures. One-anastomosis gastric bypass (OAGB) is an effective revision, yet pouch dilation and late RWG remain concerns. Rin…
