Laparoscopic treatment of deep pelvic endometriosis with rectal involvement

Are symptoms after a colorectal segmental resection in deep endometriosis really improved? The point of view of women before and after surgery

INTRODUCTION

Bowel endometriosis can cause debilitating symptoms. Surgical colorectal resection is often required for symptomatic relief. Aim of our study was to evaluate quality of life over a one-year follow-up period in patients submitted to a colorectal resection for the treatment of deep endometriosis. Change in intestinal and extra-intestinal symptoms, and reproductive outcome were also evaluated.

METHODS

A prospective observational study was conducted on a cohort of 20 women affected by intestinal endometriosis and submitted to a laparoscopic colorectal resection. The subjects completed a questionnaire about quality of life (SF-36), and they scored in a 100-point rank questionnaire gynecological, urinary and gastrointestinal symptoms, pre-operatively and one- year postoperatively.

RESULTS

Significant improvements were observed in all domains of the SF-36 throughout the study period. Dysmenorrhea, dyspareunia and not menstrual pelvic pain showed a significant decrease 1 year after surgery. There was also a decrease in abdominal pain, rectal bleeding and constipation but not of nausea, abdominal pain, defecation pain, tenesmus, diarrhea, mucorrhea. Also some urinary symptoms did not improve.

CONCLUSIONS

The radical surgical approach has a positive impact on quality of life, although it does not improve all the symptoms complained before surgery. Clear pre-surgical counseling and careful patient selection is suggested.

Outcomes after rectosigmoid resection for endometriosis: a systematic literature review

PURPOSE

"Endometriosis" is defined such as the presence of endometrial glands and stroma outside the uterine cavity. This ectopic condition may develop as deeply infiltrating endometriosis (DIE) when a solid mass is located deeper than 5 mm underneath the peritoneum including the intestinal wall. The ideal surgical treatment is still under search, and treatment may range from simple shaving to rectal resection. The aim of the present systematic review is to report and analyze the postoperative outcomes after rectosigmoid resection for endometriosis.

METHODS

We performed a systematic review according to Meta-analysis of Observational Studies in Epidemiology guidelines. The search was carried out in the PubMed database, using the keywords: "rectal resection" AND "endometriosis" and "rectosigmoid resection" AND "endometriosis." The search revealed 380 papers of which 78 were fully analyzed.

RESULTS

Thirty-eight articles published between 1998 and 2017 were included. Three thousand seventy-nine patients (mean age 34.28 ± 2.46) were included. Laparoscopic approach was the most employed (90.3%) followed by the open one (7.9%) and the robotic one (1.7%). Overall operative time was 238.47 ± 66.82. Conversion rate was 2.7%. In more than 80% of cases, associated procedures were performed. Intraoperative complications were observed in 1% of cases. The overall postoperative complications rate was 18.5% (571 patients), and the most frequent complication was recto-vaginal fistula (74 patients, 2.4%). Postoperative mortality rate was 0.03% and mean hospital stay was 8.88 ± 3.71 days.

CONCLUSIONS

Despite the large and extremely various number of associated procedures, rectosigmoid resection is a feasible and safe technique to treat endometriosis.

Clear cell thymic carcinoma: a case report

Clear cell thymic carcinoma is a rare and invasive tumor of the mediastinum for which there are no uniform treatment guidelines. The combination of carboplatin plus paclitaxel seems to be the most effective regimen for this disease. We report a case of locally advanced clear cell thymic carcinoma treated with this schedule, in which we observed a relevant and rapid tumor shrinkage.

Robotic hybrid technique in rectal surgery for deep pelvic endometriosis

BACKGROUND

Deep pelvic endometriosis is a complex disorder that affects 6% to 12% of all women in childbearing age. The incidence of bowel endometriosis ranges between 5.3% and 12%, with rectum and sigma being the most frequently involved tracts, accounting for about 80% of cases. It has been reported that segmental colorectal resection is the best surgical option in terms of recurrence rate and improvement of symptoms. The aim of this study is to analyze indications, feasibility, limits, and short-term results of robotic (Da Vinci Surgical System)-assisted laparoscopic rectal sigmoidectomy for the treatment of deep pelvic endometriosis.

PATIENTS AND METHODS

Between January 2006 and December 2010, 19 women with bowel endometriosis underwent colorectal resection through the robotic-assisted laparoscopic approach. Intraoperative and postoperative data were collected. All procedures were performed in a single center and short-term complications were evaluated.

RESULTS

Nineteen robotic-assisted laparoscopic colorectal resections for infiltrating endometriosis were achieved. Additional procedures were performed in 7 patients (37%). No laparotomic conversion was performed. No intraoperative complications were observed. The mean operative time was 370 minutes (range = 250-720 minutes), and the estimated blood loss was 250 mL (range = 50-350 mL). The overall complication rate was 10% (2 rectovaginal fistulae).

CONCLUSIONS

Deep pelvic endometriosis is a benign condition but may have substantial impact on quality of life due to severe pelvic symptoms. We believe that robotic-assisted laparoscopic colorectal resection is a feasible and relatively safe procedure in the context of close collaboration between gynecologists and surgeons for treatment of deep pelvic endometriosis with intestinal involvement, with low rates of complications and significant improvement of intestinal symptoms.

[Laparoscopic colorectal resection for deep pelvic endometriosis: Evaluation of post-operative outcome]

OBJECTIVES

Evaluation of mid-term functional results and the quality of life after laparoscopic colorectal resection.

PATIENTS AND METHODS

Twenty-three consecutive patients were included in a retrospective monocentric study. Postoperative functional outcomes and quality of life were analyzed.

RESULTS

The median follow-up after colorectal resection was of 24±15.7 months (6-72). Major complications occurred in three cases (12,9%) including one anastomotic stenosis, one digestive and one bladder fistula. A significant improvement in pelvic pain symptoms was observed. De novo constipation and pain on defecation occurred in respectively 23% and 42% of the cases. Transient de novo dysuria occurred in 18% of the cases. The quality of life has been significantly improved.

CONCLUSION

Laparoscopic colorectal resection is associated with unfavourable postoperative digestive and urological outcomes, such as bladder and rectal dysfunction. Radical treatment should be limited to selected patients.

Clinical outcome after CO₂ laser laparoscopic radical excision of endometriosis with colorectal wall invasion combined with laparoscopic segmental bowel resection and reanastomosis

BACKGROUND

Laparoscopic segmental bowel resection and reanastomosis for endometriosis with colorectal wall invasion can be associated with high complication rates. This study was performed to test the hypothesis that this high complication rate can be prevented and combined with a good clinical outcome, following a multidisciplinary surgical approach.

METHODS

A retrospective cohort study of all patients with deep endometriosis and colorectal invasion treated by CO₂ laser laparoscopic radical excision between September 2004 and September 2006 (n = 45) to document the clinical outcome: complications, recurrence and fertility (life table analysis), pain, quality of life (QOL) and sexual function.

RESULTS

No immediate major post-operative complications requiring surgical reintervention were recorded. Gynaecological pain (P < 0.0001), sexual function (P < 0.03) and QOL (P< 0.0001), improved significantly after a median follow-up period of 27 (range: 16-40) months. Although five patients (11%) had a surgical reintervention, histologically proven recurrent endometriosis was observed in only two (4%), with a cumulative endometriosis recurrence rate of 2.2 and 4.4% after 1 and 3 years, respectively. Thirteen of 28 patients who wanted to become pregnant conceived after surgery. One patient delivered twice. These 14 pregnancies were achieved spontaneously (n = 9) or after IVF (n = 5). The cumulative pregnancy rate was 47% after 3 years.

CONCLUSION

Pain, sexual function and QOL improved significantly and were associated with a good fertility rate and a low complication and recurrence rate after a CO₂ laser laparoscopic radical excision of endometriosis with colorectal wall invasion combined with laparoscopic segmental bowel resection and reanastomosis.

Bowel resection for deep endometriosis: a systematic review

BACKGROUND

deep endometriosis involving the bowel often is treated by segmental bowel resection. In a recent review of over 10000 segmental bowel resections for indications other than endometriosis, low rectum resections, in particular, were associated with a high long-term complication rate for bladder, bowel and sexual function.

OBJECTIVES

to review systematically segmental bowel resections for endometriosis for indications, outcome and complications according to the level of resection and the volume of the nodule.

SEARCH STRATEGY

all published articles on segmental bowel resection for endometriosis identified through MEDLINE, EMBASE and ISI Web of Knowledge databases during 1997-2009.

SELECTION CRITERIA

the terms 'bowel', 'rectal', 'colorectal', 'rectovaginal', 'rectosigmoid', 'resection' and 'endometriosis' were used. Articles describing more than five bowel resections for endometriosis, and with details of at least three of the relevant endpoints.

DATA COLLECTION AND ANALYSIS

data did not permit a meaningful meta-analysis.

MAIN RESULTS

thirty-four articles were found describing 1889 bowel resections. The level of bowel resection and the size of the lesions were poorly reported. The indications to perform a bowel resection were variable and were rarely described accurately. The duration of surgery varied widely and endometriosis was not always confirmed by pathology. Although not recorded prospectively, pain relief was systematically reported as excellent for the first year after surgery. Recurrence of pain was reported in 45 of 189 women; recurrence requiring reintervention occurred in 61 of 314 women. Recurrence of endometriosis was reported in 37 of 267 women. The complication rate was comparable with that of bowel resection for indications other than endometriosis. Data on sexual function were not found.

CONCLUSIONS

after a systematic review, it was found that the indication to perform a segmental resection was poorly documented and the data did not permit an analysis of indication and outcome according to localisation or diameter of the endometriotic nodule. Segmental resections were rectum resections in over 90%, and the postoperative complication rate was comparable with that of resections for indications other than endometriosis. No data were found evaluating sexual dysfunction.
