Outcomes of colorectal cancer treated with natural orifice surgery

Short-term and Long-term Outcomes of Colorectal Cancer Treated With Natural Orifice Specimen Extraction Surgery : a National Registry-based Study

Not applicable Interventional Cancer Institute and Hospital, Chinese Academy of Medical Sciences · NCT06350370

This study looks at how well a new, less invasive surgery called natural orifice specimen extraction works for people with colorectal cancer, by checking their recovery and outcomes after the procedure.

What this trial studies

This study evaluates the short-term and long-term outcomes of colorectal cancer patients who undergo natural orifice specimen extraction surgery (NOSES). It is a large retrospective analysis involving nearly 100 centers across China, aiming to gather comprehensive data on the safety and feasibility of this minimally invasive surgical technique. By analyzing patient demographics, perioperative data, and postoperative outcomes, the study seeks to provide robust evidence to support the clinical application of NOSES in treating colorectal cancer.

Who should consider this trial

Good fit: Ideal candidates for this study are patients with a pathological diagnosis of primary malignant tumors in the colon or rectum who meet the criteria for NOSES.

Not a fit: Patients whose postoperative diagnosis does not confirm primary malignant tumors in the colon or rectum will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding and application of minimally invasive surgical techniques for colorectal cancer, potentially leading to better patient outcomes.

How similar studies have performed: While NOSES is gaining recognition, this study aims to provide the first large-scale evidence-based evaluation of its feasibility and safety, making it a novel approach.
