Ureteral injury after laparoscopic versus open colectomy

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Urology

Background:

• Ureteral injury is a rare but serious complication of colectomy.
• The incidence and impact of ureteral injury in laparoscopic versus open colectomy require clarification.

Purpose of the Study:

• To determine the incidence of intraoperative ureteral injury in laparoscopic and open colectomy.
• To assess the independent morbidity and mortality associated with ureteral injury.

Main Methods:

• Analysis of the National Surgical Quality Improvement Program (2005-2010).
• Matched comparison of laparoscopic and open colectomy patients using coarsened exact matching (CEM).
• Multivariate logistic regression to identify independent associations.

Main Results:

• Laparoscopic colectomy (35%) showed a lower crude incidence of ureteral injury (0.53%) versus open colectomy (0.66%).
• Matched analysis revealed a 30% lower likelihood of ureteral injury with laparoscopic colectomy (OR, 0.70).
• Ureteral injury independently increased septic complications and length of hospital stay.

Conclusions:

• Laparoscopic colectomy is associated with a reduced risk of intraoperative ureteral injury.
• Ureteral injury significantly contributes to postoperative morbidity, regardless of repair during colectomy.
