Assessment of Risk Factors for Iatrogenic Genitourinary Injuries During a Proctectomy.

Abstract

It is critical to avoid iatrogenic injuries affecting genitourinary organs in order to prevent postoperative urinary or sexual dysfunction, which lead to lengthier recovery and possibly reoperation. Using the 2016-2019 American College of Surgeons National Quality Improvement Program (ACS NSQIP) Targeted Proctectomy Database, we collated 2577 patients with non-metastatic rectal cancer who underwent a laparoscopic or open proctectomy. Univariate analysis was used to identify differences in perioperative factors and genitourinary injuries (GUIs) between operative approaches, and multivariate logistic regression was used to identify independent risk factors for sustaining an intraoperative GUI. The rates of preoperative comorbidities were significantly higher among patients who received an open operation. The proportion of GUIs was also significantly higher in this patient population. Multivariate logistic regression demonstrated that patients who underwent a laparoscopic proctectomy were associated with a 51.4% lower risk of sustaining a GUI. Furthermore, >10% body weight loss in the past 6 months and ASA class 3 status were independently associated with a higher risk of GUI regardless of operation type. Patients who undergo a laparoscopic proctectomy are associated with a lower risk of GUI. On the other hand, patients with >10% body weight loss and ASA class 3: Severe Systemic Disease were associated with a higher risk of GUI.
