Background
Isolated sleeve gastrectomy is being used with increasing frequency for the treatment of morbid obesity. This study was done
to determine the potential benefit of placing a band of processed human dermis around the upper portion of a sleeve gastrectomy
to prevent late dilatation and weight gain.
Methods
Twenty-seven patients underwent a sleeve gastrectomy followed by placement of a band of biological tissue (AlloDerm®) placed
6 cm from the gastroesophageal junction. The results were compared to 54 patients with a Roux-en-Y gastric bypass (GBP), matched
for sex, age, and initial body mass index.
Results
All 27 patients had improvement or resolution of their diabetes, hypertension, hyperlipidemia, and sleep apnea after banded
sleeve gastrectomy (BSG) similar to the control GBP group. There were no deaths, but one patient had a pulmonary embolus and
another had a presumed leak. Symptoms of gastroesophageal reflux disease generally improved. Overall, results were almost
identical to patients with GBP.
Conclusions
BSG provides results comparable to GBP in the short-term follow-up, but avoids potential long-term complications including
internal hernias, postoperative bowel obstructions, anastomotic complications of the jejunojejunostomy, hypoglycemia, bacterial
overgrowth, and a spectrum of malabsorptive problems. While this study documents the feasibility and possible benefits of
this modification, prospective controlled studies with long-term follow-up are needed to establish its place in procedures
for surgical weight loss.
