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.
