Rectal Shaving Using Plasma Energy in Deep Infiltrating Endometriosis of the Rectum: Four Years of Experience.

STUDY OBJECTIVE

To evaluate postoperative complications, digestive function and fertility outcomes in patients managed by rectal shaving using plasma energy in deep infiltrating endometriosis of the rectum.

DESIGN

A single-center retrospective cohort study using data recorded prospectively.

DESIGN CLASSIFICATION

Canadian Task Force classification II-2.

SETTINGS

Department of Gynecology and Obstetrics of Rouen University Hospital (France).

PATIENTS

One hundred and ten patients treated between December 2012 and December 2016.

INTERVENTIONS

Laparoscopic rectal shaving using plasma energy.

MEASUREMENTS AND MAIN RESULTS

Clinical history, baseline symptoms, preoperative assessment, intraoperative findings, and postoperative outcomes were recorded prospectively. Follow-up evaluations were performed at 1 year and 3 years. Mean age of patients was 37 ± 6.4 years. Most patients had rectal nodules infiltrating either the mid or upper rectum and measuring <3 cm long. No intraoperative complications were recorded. One patient with multiple previous surgical procedures presented with a postoperative rectovaginal fistula (0.9%), and 1 patient presented with a postoperative rectouterine fistula treated exclusively with antibiotics (0.9%). Two patients (1.8%) had bladder atony necessitating ≥3 weeks of daily self-catheterization. Four patients (3.6%) had Clavien-Dindo grade I complications, 12 (10.9%) had grade II complications, 1 (0.9%) had a grade IIIa complication, 5 (4.5%) had grade IIIb complications, and 1 (0.9%) had a grade 4a complication. The vast majority of patients (n = 103 patients; 93.6%) were free of serious complications. Significant improvements in constipation and gastrointestinal quality of life were recorded at 1 year and 3 years postoperatively. Thirty-two patients attempted pregnancy after surgery (29.1%), and 17 of them conceived (53.1%).

CONCLUSIONS

Rectal shaving using plasma energy allows for a low rate of postoperative complications with good digestive function and fertility outcomes and appears to be suitable in selected women with symptomatic rectal endometriosis.
