Measuring the Anatomical Relationship of Key Arteries in Rectal Cancer Surgery

A Prospective, Observational Study of the Anatomical Localization of the Inferior Mesenteric Artery in Relation to the Left Colonic Artery During Laparoscopic Radical Surgery for Rectal Cancer

Observational Tang-Du Hospital · NCT05651971

This study is trying to see how the key arteries and veins are positioned in patients with rectal cancer to help doctors preserve an important artery during surgery.

What this trial studies

This observational study aims to measure the anatomical distances between the left colonic artery (LCA), inferior mesenteric artery (IMA), and inferior mesenteric vein (IMV) in patients undergoing laparoscopic radical resection for rectal cancer. By analyzing intraoperative data, the study seeks to provide a precise anatomical basis for preserving the LCA during surgery. The outcomes will include various surgical metrics such as operation time, blood loss, and postoperative recovery indicators, which will help assess the efficacy of the surgical approach.

Who should consider this trial

Good fit: Ideal candidates are patients with a pathological diagnosis of rectal cancer who are eligible for laparoscopic radical resection and agree to participate.

Not a fit: Patients with a history of lower abdominal surgery, those who cannot undergo laparoscopic surgery, or those with severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance surgical outcomes and reduce complications for rectal cancer patients undergoing laparoscopic procedures.

How similar studies have performed: While this study focuses on a specific anatomical measurement, similar observational studies have shown success in improving surgical techniques and outcomes.
