简要总结
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.
详细描述
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.

结局指标
主要结局
correlation between bowel symptoms and rectosigmoid perfusion before the nodule removal
时间窗: intraoperative
comparison between bowel symptoms, assessed through validated questionnaires (Knowles-Eccersley-Scott-Symptom Questionnaire and Gastrointestinal Quality of Life Index) and rectosigmoid perfusion, measured before the nodule removal using indocyanine green and a scale from 0 to 4.
次要结局
- correlation between bowel perfusion after rectal surgery and post-operative complications(up to three months after surgery; from date of surgery until the date of first documented complication, assessed up to 3 months)
- correlation between bowel symptoms and rectosigmoid perfusion after the nodule removal(up to three months after surgery)
