Abstract
Background
Although some patients attain good outcomes after adjustable gastric band (LAGB), a certain quantity have experienced complications and insufficient weight loss. The objective of this study is to assess the safety and outcome of laparoscopic sleeve gastrectomy (LSG) as a conversion surgery after a failed LAGB.
Methods
This is a retrospective analysis of 40 patients who received LSG as conversional surgery from 2009 to 2012 in Al Amiri Hospital, Kuwait. Data analyzed included percentage of excessive weight loss (EWL%), body mass index (BMI), and postoperative complications. Paired
t
test was utilized to evaluate total weight loss after both procedures.
Results
Among the 40 patients that underwent conversion surgery, the mean age was 36 years old, 34 (85 %) of which were females. Follow-up for LAGB was 1 to 11 years (median, 4.5 years) and 6 months to 3 years (median, 1 year) for LSG. Mean BMI before LAGB was 44 kg/m
2
(SD = 7.2) and mean weight was 117.2 kg (SD = 25.1). A percentage of 20 % achieved good outcomes and 7.5 % experienced complications and 60 % insufficient weight loss. Median EWL% achieved with LAGB was 11.5 %, and after LSG, a median EWL% of 56.9 % was recorded. After conversional surgery, a significant drop in BMI was noted with
p
value < 0.002.
Conclusions
Laparoscopic conversion from LAGB to LSG may be considered as an alternative for patients with a failed LAGB procedure. However, a longer follow-up study is required to validate the results.
