Introduction: The American College of Surgeons Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (ACS MBSAQIP) surgical risk calculator was established to assist physicians to predict postoperative weight loss, body mass index (BMI), as well as complications related to surgery. Our goal in this study was to determine the predictive ability of the MBSAQIP risk calculator in predicting postoperative outcomes in patients undergoing laparoscopic sleeve gastrectomy.

Methods: A retrospective chart review was completed for 55 patients that underwent laparoscopic sleeve gastrectomy surgery at a single institution from 2021 to 2022. Patient demographics and preoperative risk factors were manually entered into the calculator and the predicted complication risks were compared with observed complication rates.

Results: Our data shows that the MBSAQIP calculator was accurate on predicting postoperative weight loss for at the 3rd, 6th, 9th, and 12th months, which was statistically significant (p=0.001). Furthermore, BMI prediction after first 3,6,9 and 12 months of surgery was also found to be statistically significant (p=0.003). However, postoperative resolution of underlying comorbidities such as sleep apnea and gastroesophageal reflux disease (GERD), was not accurately predicted by the risk calculator.

Conclusion: This study shows that the MBSAQIP risk calculator can be accurately used to predict estimated weight loss and BMI at 3, 6, 9, and 12 months for patients undergoing laparoscopic sleeve gastrectomy. However, the calculator was not accurate in predicting the remission of comorbidities.
