Obesity surgery

The epidemic of obesity is engulfing developed as well as developing countries like India. We present our 7-year experience with laparoscopic sleeve gastrectomy (LSG), Roux-en-Y gastric bypass (RYGB), and mini-gastric bypass (MGB) to determine an effective and safe bariatric and metabolic procedure. ⋯ RYGB and MGB act on the principle of restriction and malabsorption, but MGB superseded RYGB in its technical ease, efficacy, revisibility, and reversibility. Mortality was zero in MGB. %EWL and resolution of comorbidities were highly significant in MGB. Based on this audit, we suggest that MGB is the effective and safe procedure for patients who are compliant in taking their supplements. LSG may be done in non-compliant patients and those ready to accept weight regain.

Bariatric surgery improves lipid profile. A still unanswered question is whether this improvement is merely weight-dependent or also results from factors inherent to specificities of the bariatric procedure. We aimed to study lipid profile 1 year after bariatric surgery and compare its changes between the different procedures in patients matched for initial weight and weight loss. ⋯ RYGB is the only bariatric surgery that reduces TC and LDL in age-, sex-, BMI- and EWL-matched patients. All three procedures improved TG and HDL similarly when the confounding effect of weight loss is eliminated.

Sleeve gastrectomy plus side-to-side jejunoileal anastomosis (JI-SG), a relatively new approach to bariatric surgeries, has shown promising results for treating obesity and metabolic comorbidities. This study investigated the feasibility and safety of JI-SG in weight loss and diabetes remission compared with sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). ⋯ JI-SG induced higher ghrelin and GLP-1 levels and improved glycemic control in Zucker diabetic fatty rats. Compared with SG and RYGB, JI-SG appeared to be a simple, relatively safe, and more effective procedure for treating type 2 diabetes and obesity in this animal model.

As most bariatric procedures are performed by laparoscopy, hospital stay is exceptionally short, despite the habitus of patients and the rather extensive intra-abdominal surgery. To facilitate postoperative mobilization, most patients are given repeated single doses of morphine, a drug with several side effects. We aimed to evaluate the effect of preoperative treatment with a tablet of slow-release morphine (SRM) on postoperative analgesic consumption and length of stay (LOS) in laparoscopic gastric bypass (LGBP). ⋯ Preoperatively administered slow-release morphine significantly reduced the need for postoperative analgesics and shortened hospital stay, without side effects or other complications. At our department, the studied regime is now routinely used in all bariatric surgery and we have started to use the concept in other groups of surgical patients.

Obstructive sleep apnea (OSA) occurs in 70-80% of bariatric surgery patients. Patients with severe OSA (apnea/hypopnea index (AHI) >30/h) are postoperatively admitted to an intensive care unit (ICU) for continuous monitoring, to prevent complications. The aim of this study was to assess the necessity of routine postoperative monitoring at an ICU of severe OSA patients after bariatric surgery, attempting to prevent and detect cardiorespiratory complications. ⋯ Patients with severe OSA and adequate CPAP use are at low risk of cardiopulmonary complications after (laparoscopic) bariatric surgery. Routine admission to an ICU might be superfluous. However, continuous digital oximetry remains essential.
