Postoperative digestive function after radical versus conservative surgical philosophy for deep endometriosis infiltrating the rectum.

OBJECTIVE: To compare delayed digestive outcomes in women managed by two different surgical philosophies: a radical approach mainly related to colorectal resection, and a conservative approach involving rectal shaving and rectal nodule excision.

DESIGN: "Before and after" comparative retrospective study.

SETTING: University tertiary referral center.

PATIENT(S): Seventy-five patients managed by surgery for deep endometriosis infiltrating the rectum.

INTERVENTION(S): Twenty-four women were managed during a period when surgeons pursued a radical philosophy toward treatment, and 51 women were managed during a period when a conservative philosophy was adopted.

MAIN OUTCOMES MEASURE(S): Standardized gastrointestinal questionnaires: the Gastrointestinal Quality of Life Index, the Knowles-Eccersley-Scott Symptom Questionnaire, the Bristol Stool Score, and the Fecal Incontinence Quality of Life Score.

RESULT(S): Preoperative patient characteristics, rectal nodule features, and associated localizations of the disease were comparable between the two groups. During the radical period, colorectal resection was carried out in 67% of patients, whereas during the second period only 20% of women underwent colorectal resection. Women managed according to the conservative philosophy had significantly improved results on the Knowles-Eccersley-Scott Symptom Questionnaire, Gastrointestinal Quality of Life Index, and depression/self-perception Fecal Incontinence Quality of Life Score, and significantly improved values for various items related to postoperative constipation: unsuccessful evacuatory attempts, feeling incomplete evacuation, abdominal pain, time taken to evacuate, difficulty evacuating causing a painful effort, and stool consistency.

CONCLUSION(S): It seems that reducing the rate of colorectal resection leads to better functional outcomes in women presenting with rectal endometriosis, lending support to the conservative surgical philosophy over mandatory colorectal resection.
