What are the results of laparoscopic re-operative rectal surgery?

Abstract

IntroductionReoperative rectal surgery is challenging, performed selectively by experienced colorectal surgeons. The minimally invasive approach has not been well defined. This study reviewed the results of laparoscopy in this challenging setting. MethodsRetrospective analysis of patients who underwent trans-abdominal re-operative rectal surgery from 2010 to 2019 was performed. ResultsSeventy-eight patients [35 females (45%); BMI 25kg/m2) were included. Reasons for reoperation were recurrent cancer in 18 (43%) patients and anastomotic failure in 57 (73%). Twenty-two (28%) had laparoscopic surgery and 4 had attempted laparoscopy converted to laparotomy. A higher success rate was noted for laparoscopy with prior laparoscopic surgery. Benefits of laparoscopy included significant reduction in length of stay (6.7 vs 9.7 days, p = 0.012) and abdominal superficial surgical site infection (0% vs 25%, p < 0.001) and higher rate of achieving bowel continuity compared to laparotomy (77% vs 50%, p = 0.021) ConclusionsReoperative laparoscopic rectal surgery is safe and feasible in the context of a high-volume laparoscopic surgeon with substantial experience in redo proctectomies. It offers clear benefits including decreased surgical site infection rates and length of stay.
