Abstract

Purpose: With the obesity epidemic, the number of bariatric procedures is increasing, and although considered relatively safe, major postoperative complications still occur. In cancer surgery, major complications such as reoperations have been associated with deteriorated mid/long-term outcomes. In obesity surgery, the effects of reoperations on postoperative weight loss and associated comorbidities remain unclear. The aim of this study was to assess mid-term weight loss and comorbidities following early reoperations in obesity surgery.

Methods: A population-based cohort study was performed within the Dutch Audit for Treatment of Obesity (DATO), including all patients that underwent a primary gastric bypass procedure or sleeve gastrectomy. Follow-up data was collected up until 5 years postoperatively on percentage total weight loss (%TWL) and comorbidities.

Results: A total of 40,640 patients underwent a gastric bypass procedure or sleeve gastrectomy between 2015 and 2018. Within this cohort, 709 patients (1.7%) suffered a major complication requiring reoperation within 30 days. %TWL at 24 months was 33.1 ± 9.2 in the overall population, versus 32.9 ± 8.7 in the patients who underwent a reoperation (p=0.813). Both analysis per year and Cox regression techniques revealed no differences in long-term follow-up regarding percentage TLW, and weight loss success rates (%TWL>20%) in patients who underwent a reoperation compared to patients without reoperation. At 5 years, the availability of follow-up data was low. No differences were observed in the remission of comorbidities.

Discussion: Major complications requiring reoperation within 30 days of gastric bypass surgery or sleeve gastrectomy did not affect long-term outcomes with regard to weight loss or remission of comorbidities.

Keywords: Comorbidities; Mid-term follow-up; Percentage total weight loss; Reoperations.
