Uterine Manipulators Enhance Laparoscopic Rectal Surgery Outcomes: Study

A recent study published in BMC Surgery found that uterine manipulators improve surgical exposure in laparoscopic rectal procedures in women without compromising oncological or perioperative outcomes.

The research analyzed female patients undergoing laparoscopic rectal resection for benign and malignant conditions, comparing those in whom uterine manipulators were used with those operated on without them. Surgeons reported enhanced visualization of the deep pelvis, which is often restricted in women due to uterine mobility and narrower pelvic dimensions. Improved access allowed for precise dissection around critical structures such as the rectum, ureters, and neurovascular bundles, facilitating safer and more efficient surgery. Importantly, the use of uterine manipulators did not significantly increase operative time, intraoperative blood loss, or postoperative complications. Oncological parameters—including total mesorectal excision quality, lymph node harvest, and circumferential resection margin—remained consistent across both groups, confirming that manipulator use does not compromise cancer-related outcomes. Functional outcomes, such as urinary and sexual function, were similarly unaffected, reinforcing the safety of this approach.
