Overview

we aim to evaluate the success of intraoperative transrectal ultrasound in measuring the depth and extent of bowel involvement in patients preoperatively diagnosed with intestinal endometriosis using transvaginal ultrasound and MRI, and who are planned for bowel resection

Detailed description

This is a prospective, single-arm study aimed at evaluating the efficacy of intraoperative transrectal ultrasound (TRUS) in assessing rectal infiltration depth and length in patients with bowel involvement due to deep infiltrative endometriosis (DIE). The study will include 15-40 female patients aged 18-55, diagnosed with intestinal endometriosis preoperatively using transvaginal ultrasound and MRI, and scheduled for bowel resection.

Preoperative evaluations will include pelvic examination, imaging (TVUS and MRI), and pain assessment using a visual analog scale (VAS). During surgery, TRUS will be used to measure the depth and length of rectal involvement, and findings will be compared with preoperative MRI results. Data will be analyzed using statistical methods, including sensitivity, specificity, and ROC curve analysis, to determine the diagnostic performance of TRUS.

The study will be conducted at Istanbul Başakşehir Çam and Sakura City Hospital, with multidisciplinary contributions from gynecology, radiology, and general surgery teams.

Primary outcome measures

  • Intraoperative transrectal ultrasound of the rectal involvement of the deep infiltrating endometriosis will be compared with preoperative MRI [Time frame: From enrollment to the 16 months]
Secondary outcome measures (1)
  • Demographic informations, patient characteristics, disease related pain scores, surgical informations [Time frame: From enrollment to 16 months.]

Eligibility criteria

Inclusion criteria

  • The study will include a minimum of 15 female patients aged 18-55 with bowel involvement due to deep infiltrative endometriosis, requiring bowel resection.

Exclusion criteria

Patients with bowel endometriosis who does not require bowel resection, patients who have other bowel diseases, such as rectal tumors, Crohn's disease, or ulcerative colitis, will be excluded.
