Obesity surgery
-
Laparoscopic sleeve gastrectomy (LSG) is one of the most commonly performed bariatric procedures for treatment of morbid obesity. Despite its popularity, it is not without risks, the most serious of which is the staple line leak. Staple line leaks are difficult to manage and require significant resources in the form of surgical, radiological and endoscopic interventions; long hospital and intensive care stay and significant morbidity. International experience is slowly emerging, but there are still no clear guidelines regarding optimal management of leaks. This study aims to describe the experience of endoscopic management of these leaks by the authors and the development of a customised stent for this condition. ⋯ The use of SEMS in conjunction with complementary endotherapy has shown to be both safe and effective in treating sleeve leaks; however, migration is the limiting factor for optimal management. Recent improvements in stent design, such as the one proposed in this paper, show promise in addressing this problem. Earlier use of SEMS seems to reduce the time till closure as well as the total hospital stay, as is apparent from our data.

Observational Study
Chronic Renin-Angiotensin System (RAS) Blockade May Not Induce Hypotension During Anaesthesia for Bariatric Surgery.
The use of angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARB) for the treatment of hypertensive obese patients is steadily increasing. Some studies have reported that the use of these drugs was associated with an increased risk of hypotensive episodes, during general anaesthesia. The number of bariatric procedures is also increasing worldwide, but there is a lack of studies investigating the hypotensive effect of renin-angiotensin system (RAS) blockers in severely obese patients during general anaesthesia for bariatric surgery. ⋯ A progressive reduction of both systolic and diastolic blood pressure values was observed without significant differences between the two groups. A similar trend of heart rate values was observed. In conclusion, our pilot study suggests that RAS blockers may be continued during the perioperative period in patients undergoing bariatric surgery, without increasing the risk of hypotensive episodes.

A retrospective study was undertaken to define the efficacy of both mini gastric bypass or one anastomosis gastric bypass (MGB/OAGB) and sleeve gastrectomy (SG) in type 2 diabetes mellitus (T2DM) remission in morbidly obese patients (pts). ⋯ A significant BMI decrease and T2DM remission unrelated from weight loss were recorded for both procedures if compared to baseline values. At univariate and multivariate analyses, MGB/OAGB seems to outperform significantly SG. Four independent variables able to influence T2DM remission at 12 months have been identified.

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.
