Abstract
Background:No robust data are available on the safety of primary bariatric and metabolic surgery (BMS) alone compared to primary BMS combined with other procedures.
Objectives:The objective of this study is to collect a 30-day mortality and morbidity of primary BMS combined with cholecystectomy, ventral hernia repair, or hiatal hernia repair.
Setting:This is as an international, multicenter, prospective, and observational audit of patients undergoing primary BMS combined with one or more additional procedures.
Methods:The audit took place from January 1 to June 30, 2022. A descriptive analysis was conducted. A propensity score matching analysis compared the BLEND study patients with those from the GENEVA cohort to obtain objective evaluation between combined procedures and primary BMS alone.
Results:A total of 75 centers submitted data on 1036 patients. Sleeve gastrectomy was the most commonly primary BMS (N = 653, 63%), and hiatal hernia repair was the most commonly concomitant procedure (N = 447, 43.1%). RYGB accounted for the highest percentage (20.6%) of a 30-day morbidity, followed by SG (10.5%). More than one combined procedures had the highest morbidities among all combinations (17.1%). Out of overall 134 complications, 129 (96.2%) were Clavien-Dindo I-III, and 4 were CD V. Patients who underwent a primary bariatric surgery combined with another procedure had a pronounced increase in a 30-day complication rate compared with patients who underwent only BMS (12.7% vs. 7.1%).
Conclusion:Combining BMS with another procedure increases the risk of complications, but most are minor and require no further treatment. Combined procedures with primary BMS is a viable option to consider in selected patients following multi-disciplinary discussion.
