"Top Ten" Paper by Sandhya Kumar Headlines Strong Showing by UCSF Bariatric Surgery During Obesity Week

UCSF Bariatric Surgery Program
December 19, 2017

Sandhya Kumar, M.D., MIS/Bariatric Surgery clinical fellow at UCSF, presented her "Top 10" paper, Is laparoscopic sleeve gastrectomy safer than laparoscopic gastric bypass? A comparison of complications and mortality using the MBSAQIP data registry, at the 34th Annual Meeting of the American Society for Metabolic and Bariatric Surgery (ASMBS) during "Obesity Week". Kumar was the lead-off presenter in the ASMBS abstracts 2017 paper sessions on October 31st.

Dr. Kumar's paper headlined a strong overall showing by UCSF Bariatric Surgery during "Obesity Week", evidencing the program's strong commitment to research, and paralleling its clinical excellence as an accredited Comprehensive Bariatric Surgery Center. Later, Dr. Kumar gave a second podium talk, and Stephanie Wood, MB BCh, MHs, the 2016-17 MIS/Bariatric Surgery fellow at UCSF, presented two papers.

Stanley J. Rogers, M.D., Bariatric Surgery Program Director, Jonathan Carter, M.D., MIS/Bariatric Surgery Fellowship Director, and gastrointestinal/bariatric surgeon Matthew Y.C. Lin, M.D. were co-authors on each of the papers. UCSF general surgery resident Barbara Hamilton, M.D. was also a co-author on one paper.

"Top 10 Paper" Summary

Is laparoscopic sleeve gastrectomy safer than laparoscopic gastric bypass? A comparison of complications and mortality using the MBSAQIP data registry.
Laparoscopic sleeve gastrectomy is rapidly gaining popularity and is now the most commonly performed operation for weight-loss (bariatric) surgery, but its risk profile is still being understood. The goal of the study was to compare the two main bariatric surgery operations, laparoscopic sleeve gastrectomy, and laparoscopic roux-en-y gastric bypass (which has long been the gold-standard) in terms of operative complications within 30 days. We used machine learning and traditional regression techniques to build a statistical model for complications after surgery using the newly released Metabolic and Bariatric Surgery Quality Improvement Data Registry (MBSAQIP), which captures over 168,000 cases across the United States and Canada. We found that even when adjusted for patient comorbidities, laparoscopic sleeve gastrectomy had about half the risk-adjusted odds of leak, major complications, and death. In fact, the type of operation performed was the strongest predictor of post-operative complications. This supports the idea that laparoscopic sleeve gastrectomy is a significantly safer operation in terms of perioperative complications. These results will inform preoperative pre-operative discussion and help chose the right operation for a given patient.
