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.
