Although this was a non-randomized study, the results found a considerable improvement in the incidence of morbidity and mortality, and a remarkable decrease in the frequency of leaks.
This report describes the authors' early outcomes with implantable gastric stimulation (IGS) used to achieve weight loss in patients with a low body mass index (BMI). After prescreening of potential candidates with a selection algorithm, 24 patients (21 women and 3 men) with a low BMI (30-34.9) underwent IGS implantation at two centers. The patients had a mean age of 43 years (range, 32-60 years), a mean BMI of 33 (range, 30-36), and a mean weight of 92 kg (range, 80-117 kg). At this writing, 6 months postoperatively, there have been no serious adverse events related to the device. The mean percentage of excess weight loss (EWL) was 5.9%, with three patients explanted because of noncompliance. The mean waist circumference decreased 5.8%, which was significant (p = 0.009). A subset of nine patients (37.5%) had an EWL exceeding 10% (mean, 20.1%). A subset of low BMI patients lost a clinically significant amount of weight with IGS within 6 months. Further study is required for better identification of potential candidates for this novel approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
