NCT05911152

Brief Summary

The goal of this observational study is to explore the safety and feasibility of laparoscopic intracorporeal anastomosis in colorectal cancer surgery. The main questions it aims to answer are: 1. If intracorporeal anastomosis is safe in terms of short-term outcome? 2. If intracorporeal anastomosis can achieve the same oncological outcome as conventional extracorporeal anastomosis?

Study Population

Patients underwent laparoscopic colorectal surgery with intracorporeal or extracorporeal anastomosis

You may qualify if:

  • Patients voluntarily enrolled in this study and signed an informed consent form;
  • Age: 18-75 years;
  • Completion of colonoscopy and biopsy, with pathological confirmation of adenocarcinoma or high-grade intraepithelial neoplasia;
