Endometriosis, Rectum Clinical Trial
Official title:
Intraoperative Assessment of Bowel Perfusion Through Indocyanine Green in Women With Rectosigmoid Endometriosis and Its Correlation With Clinical and Surgical Data
Indocyanine green is a fluorescent dye used for the intraoperative evaluation of tissue
perfusion.
The aim of this study is to evaluate a possible correlation between rectosigmoid
vascularization and surgical and clinical data including pre and post-operative bowel
symptoms in patients needing surgery for rectosigmoid endometriosis.
Patients with symptomatic rectosigmoid endometriosis requiring laparoscopic surgery are
included in the study.
Before surgery, bowel symptoms are assessed using validated questionnaires
(Knowles-Eccersley-Scott-Symptom Questionnaire and Gastrointestinal Quality of Life Index).
Indocyanine green is administered through peripheral line. A near-infrared (NIR) camera-head
enables real-time direct visualization of bowel perfusion before and after the removal of the
rectosigmoid nodule. Rectosigmoid tract perfusion is assessed before and after the removal of
the nodule. To estimate the vascularization, a scale with a score between 0 and 4 is used.
After complete removal of rectosigmoid nodule, the post-operative follow-up will be the same
as usual after intestinal endometriosis surgery. Postoperative bowel symptoms are evaluated
using the same questionnaires.
