Study Objective: To present a detailed description of a modified natural orifice specimen extraction (NOSE) colectomy technique. We also report the postoperative outcomes of our prospective case series when compared with conventional laparoscopic bowel resection in a relatively large series of patients. Design: Canadian Task Force classification II-1. Setting: A university tertiary referral center. Patients: The last 90 consecutive patients in our care with deep infiltrating endometriosis of the bowel are presented in this study. Patients were diagnosed at the 1st Department of Obstetrics and Gynecology, Semmelweis University, Budapest, Hungary. Interventions: We performed laparoscopic bowel resection using the transrectal NOSE technique and compared the results of the new operative method (n = 30) with traditional laparoscopic bowel resection (n = 60). Measurements and Main Results: The median duration of surgery was 121 minutes in the control group and 96 minutes in the NOSE group (p =.005). According to the Clavien-Dindo classification, we observed a severe, grade IIIb or higher, overall complication rate of 3.3% among all 90 patients. In the control group, anastomosis insufficiency occurred in 3.3% of patients (2/60 cases), and in 1 patient with anastomotic leakage a rectovaginal fistula was observed (1.7%). There was no significant difference in the rates of severe postoperative complications (p =.55). The length of hospital stay in the control group was a median of 7 days (range, 5–13 days), whereas in the NOSE group it was 6 days (range, 3–11 days) (p <.001). Conclusion: According to our findings, the use of NOSE colectomy offers a shorter recovery time and can eventually lead to a shorter surgery duration compared with traditional laparoscopic bowel resection.
