Intestinal endometriotic nodules with a length greater than 2.25 cm and affecting more than 27% of the circumference are more likely to undergo segmental resection, rather than linear nodulectomy.

Study Objective: To analyze the efficacy of intestinal ultrasonography with bowel preparation (TVUSBP) for endometriosis mapping in evaluating intestinal endometriosis to choose the surgical technique (segmental resection or linear nodulectomy) for treatment.

Design: Cross-sectional observational study.

Setting: University Hospital-Center for Advanced Endoscopic Gynecologic Surgery from April 2010 to November 2014.
