What this trial studies

This observational study aims to assess the safety and feasibility of laparoscopic intracorporeal anastomosis in patients undergoing surgery for colorectal cancer. It will analyze clinical data from approximately 2,000 patients who had laparoscopic surgery between April 2016 and April 2020, comparing outcomes between those who underwent intracorporeal anastomosis and those who had extracorporeal anastomosis. The study will evaluate primary endpoints such as 3-year disease-free survival and overall survival, along with secondary endpoints including complication rates and postoperative recovery metrics.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with a confirmed diagnosis of adenocarcinoma or high-grade intraepithelial neoplasia who are eligible for laparoscopic surgery.

Not a fit: Patients with contraindications to laparoscopic surgery or those requiring emergency interventions due to complications will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into a safer and more effective surgical technique for colorectal cancer patients.

How similar studies have performed: While similar approaches have been explored, this study focuses on a specific technique in a large cohort, making it a significant contribution to existing literature.
