Comparative Study between Laparoscopic Banded Sleeve Gastrectomy and Conventional Laparoscopic Sleeve Gastrectomy

Abstract

Context: Laparoscopic sleeve gastrectomy (LSG) has become a very popular bariatric surgery because it does not require anastomosis or intestinal bypass. The gastric tube created in LSG may dilate with time and this might be a potential cause of failure. The hypothesis of the possible superiority of laparoscopic banded sleeve gastrectomy (LBSG) over the conventional one was evaluated in this study. Patients and methods: This is a randomized prospective comparative study including 40 morbid obese patients who were equally divided into two groups. Group 1, were offered LSG, while group 2 were offered LBSG. The primary endpoint was the intra-operative assessment of the procedure, whilst the secondary endpoint was the assessment of post-operative sequelae after 3, 6 and 12 months. Results: There was no significant statistical difference between performing LSG with and without using a band as regard intra-operative complications, percentage of excess weight loss (%EWL) and the post- operative one year follow-up. However, the mean operative time showed a significant statistical increase in those with LBSG due to application of mesh. Conclusion: LBSG is a safe procedure, however, it is more time-consuming than the conventional LSG. Therefore, we recommend conducting other multi-centric studies on larger number of patients that would be followed-up for a longer period of time to determine the long-term weight loss after LBSG and to detect the incidence of any additional complications from this procedure.
