Risk factors for major complications following colorectal resections for endometriosis in the USA

Abstract

Abstract Purpose We aimed to describe the incidence and identify risk factors for the occurrence of short-term major posto-perative complications following colorectal resection for endometriosis. Methods A cohort study using data from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database from 2012–2020. We included patients with a primary diagnosis of endometriosis who underwent colon or rectal resections for endometriosis. Results Of 755 women who underwent colorectal resection, 495 (65.6%) had laparoscopic surgery and 260 (34.4%) had open surgery. The major complication rate was 13.5% (n = 102). Women who underwent open surgery had a higher proportion of major complications (n = 53, 20.4% vs. n = 49, 9.9%, p < 0.001). In a multivariable regression analysis, Black race (aOR 95%CI 2.81 (1.60–4.92), p < 0.001), Hispanic ethnicity (aOR 95%CI 3.02 (1.42–6.43), p = 0.004), hypertension (aOR 95%CI 1.89 (1.08–3.30), p = 0.025), laparotomy (aOR 95%CI 1.64 (1.03–3.30), p = 0.025), concomitant enterotomy (aOR 95%CI 3.02 (1.26–7.21), p = 0.013), and hysterectomy (aOR 95%CI 2.59 (1.62–4.15), p < 0.001) were independently associated with major post-operative complications. In a subanalysis of laparoscopies only, Hispanic ethnicity, chronic hypertension, lysis of bowel adhesions, and hysterectomy were independently associated with major complications. In a subanalysis of laparotomies only, Black race and hysterectomy were independently positively associated with the occurrence of major complications. Conclusion This study provides a current population-based estimate of short-term complications after surgery for colorectal endometriosis in the USA. The identified risk factors for complications can assist during preoperative shared decision-making and informed consent process.
