Background:
Laparoscopic sleeve gastrectomy (LSG) with staple line reinforcement (SLR) is a popular and safe treatment option for morbid obesity. We have developed, devised, and described our own method of stapleless laparoscopic sleeve gastrectomy, which in our limited study appeared safe, efficacious, and potentially cost-effective.
Methods:
We analyzed the outcome of our modified LSG in a case series of three middle-aged women (median age 42 years old). Our main modification was sutured closure of the stomach rather than the commonly utilized technique of stapled closure. Our primary measure of success was the occurrence of post-operative leak. Secondary measures were (a) length of operation, (b) duration of inpatient stay, and (c) percentage of weight loss at 6 and 12 months post operation.
Results:
Median operative time = 132 min (120-195 min), and median inpatient stays were 2 days. No post-operative leaks were recorded. The median excess weight loss at 6 months was 39% of initial weight loss and 57.7% at 12 months.
Conclusions:
Stapleless LSG has the potential to be an affordable alternative to the traditional LSG. High-powered studies and a formal cost analysis are required.
