Robot-assisted total intracorporeal low anterior resection with primary anastomosis and radical dissection for treatment of stage IV endometriosis with bowel involvement: morbidity and its outcome

Robot-assisted low anterior resection with primary sigmoid rectal anastomosis/ureterolysis/hysterectomy with bilateral salpingo-oophorectomy (RALARH), and exploratory laparotomy low anterior resection with primary sigmoid rectal anastomosis/ureterolysis/hysterectomy with bilateral salpingo-oophorectomy (ELLARH). A total of eighteen patients (8 RALARH and 10 ELLARH) met the inclusion criteria. The mean age of the RALARH group was 47 and that of the ELLARH group was 36.9. There was no difference between body mass index (RALARH = 30.3 ± 6.6, 95% CI (25.7, 56.0) vs. ELLARH = 26.7 ± 7.5). Total operative time for the RALARH group was 238.5 ± 57.8 min, 95% CI: (164.5, 279.9) whereas that for the ELLARH group was 237 ± 117.7 min. There were no statistically significant differences between blood loss (RALARH = 425 ± 462.1 cc, 95% CI: (104.8, 745.2). ELLARH = 630 ± 432.2 cc) or days of hospitalization (RALARH = 5.5 ± 2.4 days, 95% CI: (3.8, 7.2) vs. ELLARH = 6.2 ± 1.6 days) in the RALARH and ELLARH groups. There were fewer complications in the RALARH group than in the ELLARH group (RALARH two complications vs. ELLARH two blood transfusion and two rectovaginal fistula), but the difference was not significant because of the small sample size. Robotic low anterior resection with primary sigmoid rectal anastomosis with ureterolysis at the time of hysterectomy and bilateral salpingo-oophorectomy for treatment of Stage IV endometriosis is a feasible and safe procedure.
