Evaluating bowel involvement in deep infiltrative endometriosis using ultrasound during surgery

Evaluation of Rectal Infiltration Depth and Length in Bowel Involvement of Deep Infiltrative Endometriosis (DIE) Using Intraoperative Transrectal Ultrasound (TRUS)

Not applicable Interventional Başakşehir Çam & Sakura City Hospital · NCT06776536

This study is testing if a special ultrasound used during surgery can help doctors better understand how deep endometriosis affects the bowel in women who need surgery for it.

What this trial studies

This study aims to assess the effectiveness of intraoperative transrectal ultrasound (TRUS) in measuring the depth and extent of bowel involvement in patients diagnosed with deep infiltrative endometriosis (DIE) who are scheduled for bowel resection. It will include 15-40 female patients aged 18-55, with preoperative evaluations conducted using transvaginal ultrasound and MRI. During surgery, TRUS will be utilized to gather data on rectal infiltration, which will then be compared to preoperative imaging results. The study will analyze the diagnostic performance of TRUS through various statistical methods.

Who should consider this trial

Good fit: Ideal candidates are female patients aged 18-55 with bowel involvement due to deep infiltrative endometriosis requiring bowel resection.

Not a fit: Patients with bowel endometriosis who do not require bowel resection or have other bowel diseases like rectal tumors or Crohn's disease will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve surgical outcomes and precision in treating bowel endometriosis.

How similar studies have performed: While the use of transrectal ultrasound in this context is innovative, similar studies have shown promise in improving diagnostic accuracy for bowel conditions.
