NCT03532074

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • correlation between bowel symptoms and rectosigmoid perfusion before the nodule removal

    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.

    intraoperative

Secondary Outcomes (2)

  • correlation between bowel symptoms and rectosigmoid perfusion after the nodule removal

    up to three months after surgery

  • 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

Study Arms (2)

laparoscopic approach

OTHER

assessment of bowel symptoms before surgery; assessment of rectosigmoid perfusion using indocyanine green; removal of rectosigmoid endometriosis nodule using a laparoscopic approach; follow up and assessment of bowel symptoms after surgery

Diagnostic Test: assessment of bowel symptoms before surgeryDiagnostic Test: assessment of rectosigmoid during laparoscopyDiagnostic Test: follow up and assessment of bowel symptoms after surgery

robot-assisted approach

OTHER

assessment of bowel symptoms before surgery; assessment of rectosigmoid perfusion using indocyanine green; removal of rectosigmoid endometriosis nodule using a robot-assisted approach; follow up and assessment of bowel symptoms after surgery

Diagnostic Test: assessment of bowel symptoms before surgeryDiagnostic Test: follow up and assessment of bowel symptoms after surgeryDiagnostic Test: assessment of rectosigmoid perfusion during robot-assisted laparoscopy

Interventions

validated questionnaires (Knowles-Eccersley-Scott-Symptom Questionnaire and Gastrointestinal Quality of Life Index) are filled in by patients with rectosigmoid endometriosis before surgery

laparoscopic approachrobot-assisted approach

indocyanine green (0.25 mg/kg) is administered through peripheral line. A near-infrared camera-head (KARL STORZ Gesellschaft mit beschränkter Haftung \& Co., Tuttlingen, Germany) is used to visualize bowel perfusion before and after the removal of the rectosigmoid nodule. To estimate the vascularization, a scale with a score between 0 and 4 is used

laparoscopic approachrobot-assisted approach

indocyanine green (0.25 mg/kg) is administered through peripheral line. The robotic Firefly imaging system (daVinciXi surgical platform; Intuitive Surgical, Sunnyvale, CA) is used to visualize bowel perfusion before and after the removal of the rectosigmoid nodule. To estimate the vascularization, a scale with a score between 0 and 4 is used
