At Massachusetts General Hospital, we believe it's important to provide safe and effective care. The Weight Center and the Department of Surgery tracks many performance measures and compares them to national data including:

  • Bariatric Surgery Case Volumes
  • Patient Ratings of Bariatric Surgeons
  • Laparoscopic Gastric Bypass
  • Laparoscopic Sleeve Gastrectomy

Bariatric Surgery Case Volumes

Mass General's bariatric surgery volumes greatly exceed the minimum to receive national accreditation, which is 125 when compared to the national average.

Bariatric programs that perform higher numbers of surgeries have better outcomes. Mass General performs a large number of bariatric surgery procedures.

Data period: January 2010 - December 2017

Patient Ratings of Bariatric Surgeons

Patients give exceptionally high ratings to Mass General bariatric surgeons. Higher percentages are better.

Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys ask patients to report on and evaluate their experiences with health care. In recent ratings, our surgeons have rated very high relative to the national average, compared to national patient ratings of all doctors.

Laparoscopic Gastric Bypass Outcomes

Patients can expect significant reductions in obesity-related conditions.

In addition to promoting weight loss, laparoscopic gastric-bypass surgery has enabled our patients to obtain significant health benefits. Within a year, many patients experience dramatic reductions in obesity-related conditions and have improved their overall health.

Laparoscopic Gastric Bypass Outcomes

Patients can expect to lose a large amount of their excess weight.

On average, our laparoscopic bypass patients have experienced substantial reduction in their excess weight as measured by their body mass index (BMI) in the year following surgery.

Laparoscopic Gastric Bypass Outcomes

The majority of Mass General's 30-day outcomes are at or better than the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSA-QIP) norms. Lower percentages are better.

At Mass General, patient safety is a priority. Our rates of complications from laparoscopic gastric bypass procedures are relatively low.

Laparoscopic Sleeve Gastrectomy Outcomes

Mass General's outcomes are comparable to the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSA-QIP) norms, given the high number of extremely complex patients we serve. Lower percentages are better.

At Mass General, patient safety is a priority. Our rates of complications from laparoscopic sleeve gastrectomy procedures are relatively low.
