Lesion size and location in deep infiltrating bowel endometriosis: Correlation with gastrointestinal dysfunction and pain.
Presence of deep infiltrating bowel endometriosis (DE) is associated with occurrence of dyschezia and gastrointestinal symptoms. The degree of the disease, the lesion length, and the location, that is, lesion-to-anal-verge distance (LAVD) of DE, as well as the severity of the symptoms appear to be correlated. Nevertheless, it is not yet known to what extent the size and LAVD of bowel DE influence the severity of gastrointestinal symptoms. The present study aims to evaluate a possible correlation of lesion location (LAVD) and size (according to the #Enzian classification) with preoperative symptoms.
In this prospective study, premenopausal patients with histologically confirmed DE undergoing modified limited nerve-vessel sparing rectal segmental bowel resection or full-thickness discoid resection were evaluated. Extent of endometriosis was defined according to the #Enzian classification during surgery. The primary outcome measure was the correlation between lesion size and location with the GI function impairment reflected by presurgical lower anterior resection syndrome (LARS) scores; the secondary outcome was differences in presurgical numeric rating scale pain scores of dyschezia, dyspareunia, and dysmenorrhea as well as the impact of concomitant DE of other locations on symptom intensity.
Of 162 consecutive patients, 151 were included in the final analysis. No significant correlation was observed between lesion size (#Enzian compartments C1/C2/C3) or LAVD and GI dysfunction reflected by LARS-like symptoms (p = 0.314 and p = 0.185, respectively) or pain symptoms (dyschezia, p = 0.440; dyspareunia, p = 0.136; and dysmenorrhea p = 0.221). Furthermore, no significant correlation was observed between lesion size and GI dysfunction when merging two severity grades (#Enzian compartments C1 plus C2 vs. C3; p = 0.611). In addition, LAVD did not affect the degree of dyschezia (p = 0.892), dyspareunia (p = 0.395), or dysmenorrhea (p = 0.705). Finally, the presence of concomitant DE lesions infiltrating the vagina/rectovaginal space (#Enzian compartment A) and/or sacrouterine ligaments/parametrium (#Enzian compartment B) did not alter the severity of preoperative dyschezia (p = 0.493) or dysmenorrhea (p = 0.128) but showed a trend toward affecting gastrointestinal function (p = 0.078) and was significantly associated with dyspareunia (p = 0.035).
In present study, we could not find a correlation between colorectal DE lesion size and location (LAVD) and gastrointestinal function impairment or intensity of dyschezia and dysmenorrhea. Additional involvement of vagina/rectovaginal space (#Enzian compartment A) and/or sacrouterine ligaments/parametrium (#Enzian compartment B) exerts a significant impact on the degree of dyspareunia in women with colorectal DE.

Long-term surgical outcomes of nerve-sparing discoid and segmental resection for deep endometriosis.
The aim of this study was to investigate long-term outcomes in terms of pain, quality of life (QoL), and gastrointestinal symptoms in women following colorectal surgery for deep endometriosis.
In this historical cohort, women who underwent surgical treatment for deep endometriosis by either nerve-sparing full-thickness discoid resection (DR) or colorectal segmental resection (SR) between March 2011 and August 2016 were re-evaluated through telephone interviews about their long-term pain symptoms, subjective overall QoL as rated using a score from 0 (worst) to 10 (optimal), and gastrointestinal outcomes reflected by lower anterior resection syndrome (LARS) following a first postsurgical evaluation (visit 1) published previously and a long-term follow-up evaluation (visit 2).
The median long-term follow-up time was 35.4 months at visit 1 and 86 months at visit 2. Of 134 patients, 77 were eligible for final analysis and 57 were lost to follow-up. Compared with presurgical values, QoL scores were significantly increased at both postsurgical evaluation visits in both the SR cohort (scores of 3, 8.5, and 10 at the presurgical visit, visit 1, and visit 2, respectively; p < 0.001) and the DR cohort (scores of 3, 9, and 10, respectively; p < 0.001). Pain scores for dysmenorrhea (SR group scores of 8, 2, and 2, respectively; p < 0.001; DR group scores of 9, 2, and 1, respectively; p < 0.001), dyspareunia (SR group scores of 4, 0, and 0, respectively; p < 0.001; DR group scores of 5, 0, and 1, respectively; p = 0.003), and dyschezia (SR group scores of 8, 2, and 2, respectively; p < 0.001; DR group scores of 9, 2, and 1, respectively; p < 0.001) significantly decreased after surgery and remained stable in both cohorts over the follow-up period. Minor and major LARS, reflecting gastrointestinal function, was observed in 6.5% and 8.1% of the SR group and in 13.3% and 6.7% of the DR group, respectively, at visit 1 and in 3.2% and 3.2% of the SR group and 0% and 0% of the DR group, respectively, at visit 2, without significant differences between the SR and DR groups.
Colorectal surgery for deep endometriosis, either by DR or SR, provides stable and long-term pain relief with low rates of permanent gastrointestinal function impairment.

Pain and fertility outcomes of nerve-sparing, full-thickness disk or segmental bowel resection for deep infiltrating endometriosis-A prospective cohort study.
Choosing the optimal treatment for bowel endometriosis, ie, conservative vs radical surgery, is under debate. We aimed to evaluate the surgical outcomes of segmental resection and disk resection regarding fertility, pain symptoms, and quality of life score of women with colorectal deep infiltrating endometriosis.
From March 2011 to December 2016, 134 consecutive patients with symptomatic deep infiltrating endometriosis of the rectosigmoid up to 25 cm from the anal verge undergoing segmental resection or disk resection were prospectively evaluated regarding reduction in pain symptoms, fertility outcomes, and complication rates according to Clavien-Dindo classification.
Of the 134 women included, segmental resection was performed in 102 (76.1%) women and disk resection was performed in 32 (23.9%) women. There was no difference in duration of surgery, complication rates, mean hospital stay, or discrepancy in hemoglobin level comparing the two groups. There was no significant difference regarding reduction of pain symptoms, fertility, and functional outcomes. One hundred and twelve (83.6%) women were followed up long-term. In both cohorts, there was a significant reported decrease in pain symptoms and increase in quality of life scores. Of all the 61 infertile women, 26 (42.6%) became pregnant spontaneously, and 13 (21.3%) by in vitro fertilization with an overall pregnancy rate of 63.4%. The overall complication rate (Clavien-Dindo III-IV) was 8 of 134 (5.9%) without statistically significant difference between the cohorts.
Both conservative surgery with disk resection, and nerve- and vessel-sparing segmental resection reduce pain symptoms with equal morbidity. Fertility is improved with surgery with both techniques.
