Bariatric Surgery: Surgical Technique Affects Patient Outcomes

In a video review study published in JAMA Surgery in December 2020, Karan Chhabra, MD, and colleagues assessed surgeons’ various technical approaches to bariatric surgery. These techniques included approaches to dissecting the proximal stomach, sleeve caliber, sleeve anatomy, staple line enforcement, and lead testing. Previously, researchers have largely left out surgical technique as a factor when studying differences in patient outcomes. Yet, the study found that certain techniques “had a meaningful relationship with their clinical outcomes, even when we adjusted for overall skill level.”
