This study evaluated the utility of CT virtual colonoscopy for preoperative assessment in eleven patients with deep colorectal endometriosis. The low-dose protocol successfully identified thirteen nodules, primarily in the rectosigmoid region, and detected significant luminal stenosis in seven cases when compared against surgical findings. While the examination quality was good in 91% of cases, the authors note that a larger study is required to confirm these preliminary results. This paper is centrally about endometriosis — specifically the diagnostic imaging and surgical planning for deep infiltrating lesions affecting the gastrointestinal tract.

Introduction

Endometriosis is defined by the presence of functional endometrium outside the uterine cavity and myometrium. Its prevalence reaches up to 15% in child-bearing aged women. Deep lesions of endometriosis mainly grow on the posterior pelvic surface (pouch of Douglas, rectovaginal septum, utero-sacral ligaments, vesico-vaginal septum). Gastrointestinal locations involve both rectum and sigmoid colon. Small bowel and ureters may also be affected. These injuries result in varied symptoms (gynecological, digestive, urinary), making diagnosis difficult and delayed. Diagnostic imaging of deep endometriosis Endovaginal ultrasound (Fig1): Up...

Methods

and Materials Eleven consecutive patients. Aged 25 to 48 years (mean age = 32 years). Digestive disease with deep endometriosis diagnosed by ultrasound and MRI. Preoperative CT virtual colonoscopy was performed and results were compared to surgical findings . Acquisition protocol: Development of an acquisition protocol suitable for young patients (low dose) and related to the disease (contrast enhancement of nodules). Bowel preparation: Laxative solution and stool tagging according to the standard protocol for virtual colonoscopy (kit Prepacol®, Micropaque Scanner®, Telebrix Gastro®, Guerbet, France CT parameters: 64...

Results

Quality of examination: Good in 91 % of cases Nodules (Fig 5): 13 nodules found in 11 patients (2 nodules for patients 5 and 11). Volume from 1.1 to 186 cm3. Digestive segments concerned (Fig 6): The digestive disease was mainly spread to the recto sigmoid Small bowel involvement was observed in one patient Impact on the luminal diameter (Fig 7): 7 of 13 nodules resulted in significant stenosis of the digestive segment (reduction of the digestive lumen diameter compared to adjacent normal bowel loops)....

Conclusion

New surgical techniques in the management of deep endometriosis (which aim to be as minimally invasive as possible) raise new questions from clinicians. CTC in the preoperative evaluation of deep endometriosis is feasible and allows to specify the digestive involvement. This contribution appears to provide satisfaction to gynecologists, guiding the surgical procedure. However, a larger study is necessary to confirm our preliminary results.
