Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
