Pillars for Surgical Treatment of Bowel Endometriosis

Colorectal endometriosis: Diagnosis, surgical strategies and post-operative complications

Objective

The present work aimed to investigate the feasibility, complications, recurrence rate, and infertility outcomes of the radical and conservative surgical methods for colorectal endometriosis in short- and long-term follow-ups.

Methods

In this prospective study, the patients with confirmed diagnosis of colorectal DIE were included from March 2015 to March 2021, who were referred to an Endometriosis Surgery Center affiliated with Shiraz University of Medical Sciences (SUMS). Information on demographics, surgical approaches, intra-operative, and post-operative findings as well as complications were collected and compared. Six- and 12-month interviews were conducted to evaluate the functional outcomes of all the procedures.

Results

Out of 3,111 patients who underwent endometriosis surgery, 837 (28.19%) with the average age of 34.2 ± 5.9 years and average ASRM score of 102.1 ± 36.8 had rectosigmoid endometriosis. Laparoscopic rectal shaving was performed in 263(30.0%) patients while 326 (37.2%) underwent segmental bowel resection, and 248 (28.30%) were treated with disc excision. Prophylactic ileostomy was performed in six (0.68%) patients and peritonitis was reported in four (0.45%). Five (0.58%) subjects developed rectovaginal fistula and one (0.11%) was diagnosed with bladder atonia. The recurrence rate was 3.8%, 1.2%, and 0.3% in rectal shaving, disc, and segmental bowel resection techniques, respectively. Dysmenorrhea, dyspareunia, and dyschezia were improved after surgery by 7.3, 9.4, and 12.5 times, respectively. We observed 25.2% of total pregnancy following the operation, the majority of which occurred in the first year after the surgery.

Conclusion

There were very few short-term or long-term complications in the three different techniques when the choice was correct.

Postoperative Complications and Stoma Rates After Laparoscopic Resection of Deep Infiltrating Endometriosis with Bowel Involvement

OBJECTIVE

 The purpose was to assess the rates of postoperative complications and the need of temporary stoma of laparoscopic surgical treatment for bowel endometriosis in a referral center.

METHODS

 The surgical indication, type of operation, operative time, length of hospital stay, need for a temporary stoma, rate of conversion to open surgery, postoperative complications were evaluated.

RESULTS

 One-hundred and fifty patients were included. The average duration of surgery was significantly longer for segmental resection (151 minutes) than for disc excision (111.5 minutes, p < 0.001) and shaving (96.8 minutes, p < 0.001). Patients with segmental resection had longer postoperative lengths of hospital stay (1.87 days) compared with patients with disc excision (1.43 days, p < 0.001) and shaving (1.03 days, p < 0.001). A temporary stoma was performed in 2.7% of patients. Grade II and III postoperative complications occurred in 6.7% and 4.7% patients, respectively.

CONCLUSION

 Laparoscopic intestinal resection has an acceptable postoperative complication rate and a low need for a temporary stoma.

LATE IMPACT OF THE LAPAROSCOPIC TREATMENT OF DEEP INFILTRATING ENDOMETRIOSIS WITH SEGMENTAL COLORECTAL RESECTION

BACKGROUND

Deep infiltrating colorectal endometriosis may severely affect the quality of life and fertility of patients. Although segmental resection is a therapeutic option that provides positive outcomes in the management of symptoms, its functional effects are still unproven.

AIM

Assess the late impact of the laparoscopic approach in treating deep infiltrating endometriosis with segmental colorectal resection.

METHODS

Prospective case series of 46 patients submitted to laparoscopic treatment of deep infiltrating endometriosis with segmental colorectal resection between 2013 and 2016. Fertility, gynecological and bowel symptoms were assessed at the preoperative period and at three and 12 months (or more) after the procedure.

RESULTS

Preoperative interview assessed the prevalence of infertility (45.6%), gynecological (87%) and intestinal (80.4%) symptoms. At the third month after the procedure a significant reduction in the prevalence of gynecological symptoms (p<0,001), tenesmus (p=0,001) and dysquesia (p=0,002) was observed. After a period of 12 months or more following the procedure a significant reduction in the prevalence persisted for dysmenorrhea (p=0,001), deep dyspareunia (p=0,041), chronic pelvic pain (p=0,011) and dysquesia (p=0,001), as compared to the preoperative period. Total pregnancy rate was 57.1% and spontaneous pregnancy 47.6%.

CONCLUSION

The treatment of deep infiltrating endometriosis using segmental colorectal resection has provided early and late relief of gynecological and bowel symptoms. The outcomes also indicate a positive impact on the fertility of infertile patients.
