This study evaluated long-term outcomes after colorectal surgery for deep endometriosis, comparing nerve-sparing full-thickness discoid resection (DR) versus nerve-sparing segmental resection (SR) in women treated between March 2011 and August 2016 and reassessed for pain, quality of life, and gastrointestinal (GI) symptoms. Among 77 women with available follow-up (median 86 months), both surgical approaches showed significantly decreased quality-of-life scores immediately postoperatively and stable reductions in multiple pain measures over time, including dysmenorrhea, dyspareunia, and dyschezia, with pain remaining improved across follow-up. GI function assessed using minor/major lower anterior resection syndrome (LARS) occurred infrequently and without significant differences between SR and DR at follow-up visits. The analysis was limited by substantial loss to follow-up (57 of 134 patients), which may affect generalizability. This paper is centrally about endometriosis — specifically long-term pain, quality of life, and gastrointestinal outcomes after nerve-sparing discoid versus segmental colorectal resection for deep endometriosis.

Abstract

Purpose Endometriosis predominantly affects women in their reproductive age and may impair quality of life (Qol) and fertility. Deep lesions are usually related with more adverse pain and gastrointestinal (GI) outcomes (1) (2, 3),(4). The optimal treatment modality for symptomatic DE should improve QoL and preserve or improve fertility with low recurrence and complication rates. Within this, several studies have demonstrated a significant decrease in pain symptoms in women following sugical treatment for colorectal DE (5, 6),(7),(8). However, there is an ongoing debate in how far surgical radicality reflected by eitther segmental colorectal resection, discoid resection or so-called rectal shaving is really warranted in order to achieve optimal surgical outcomes including preservation of gastrointestinal function (9). The aim of this study was to investigate the long-term outcomes in terms of pain, QoL and gastrointestional (GI) symptoms in women following colorectal surgery for deep endometriosis (DE).

Methods

Women who underwent surgical treatment for DE by either nerve sparing full thickness discoid resection (DR) or colorectal segmental resection (10) between March 2011 to August 2016 were re-evaluated regarding pain symptoms, QoL and GI outcomes.

Results

The median follow-up time was 86 months at final visit 2. Out of 134 patients, 77 were were eligible for final analysis and 57 were lost to follow-up. Compared to presurgical values, significantly decreased OoL scores were observed at the postoperative visit 1 and 2 in both, SR (3 (2-4) vs. 8.5 (8-9) and 10 (8-10) p < 0.001, SR group) and DR cohorts (3 (2-4) vs. 9 (8-10) and 10 (0-10), p < 0.001). Pain scores for dysmenorrhea (8 (7-9) vs. 2 (0-4) and 2 (0-4), p < 0.001, SR group and 9 (8-10) vs 2 (0-3) and 1 (0-2), p < 0.001 in DR patients), dyspareunia (4 (0-6) vs. 0 (0-1) and 0 (0-2), p < 0.001, SR; 5 (0-7) vs. 0 (0-4) and 1 (0-2), p=0.003, DR) and dyschezia (8 (7-9) vs. 2 (0-4) and 2 (0-4), p < 0.001, SR and 9 (8-10) vs. 2 (0-3) and 1 (0-2), p < 0.001, DR), significantly decreased after surgery and remained stable in both cohorts over the follow-up period. Gastrointestinal function reflected by minor and major lower anterior resection syndrome LARS) was observed at visit 1 and 2 in 6.5% and 8.1% and 3.2% and 3.2% of SR patients and 13.3% and 6.7% and 0% and 0% of DR patients without significant differences between SR and DR.

Conclusion

Colorectal surgery for DE either by discoid or segmental resection provides stable and long-term pain relief with low rates of permanent GI function impairment [1] [2] [3] [4] [5] [6] [7] [8] [9] [10].
