Rethinking Post-Bariatric Care: Anorectal Morbidity Following Sleeve Gastrectomy and Roux-en-Y Gastric Bypass

BACKGROUND: Bariatric surgery is a prevalent and effective treatment for morbid obesity, yet its potential long-term effects on anorectal health remain an under-investigated aspect of post-operative care. This study aimed to meticulously evaluate the incidence and the degree of severity of two common anorectal conditions, anal fissures and hemorrhoids, in a substantial cohort of patients following either sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB), two frequently performed bariatric procedures. Understanding these potential post-surgical morbidities is crucial for a comprehensive approach to patient management. METHODS: A retrospective cohort study at a large tertiary referral center (2015-2023) included 280 patients (200 SG, 80 RYGB). Detailed pre- and post-operative data on anorectal conditions, bowel habits, and surgical outcomes were extracted from electronic records and statistically analyzed. RESULTS: The overall incidence of new-onset anorectal disorders (defined as the development of at least one of the conditions) was significantly higher in the RYGB group (47.5%) compared to the SG group (32.5%) ( P
