Comparison of Postoperative Anal Function Between Parks and Bacon Techniques in Low Rectal Cancer

Comparison of Postoperative Anal Function Between Different Anastomosis Techniques(Parks Versus Bacon) in Low Rectal Cancer: A Prospective, Multicentric and Randomized Controlled Study

• Status: Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 256 (estimated)
• Sponsor: Sixth Affiliated Hospital, Sun Yat-sen University · Academic / Other

• Healthy volunteers: Not accepted

Summary

The goal of this study is to compare the postoperative anal function of patients with ultra-low rectal cancer after Parks operation (colon anal anastomosis) and Bacon operation (colon anal pull-out anastomosis), which may provide clinical evidence for the improvement of anal function and quality of life. The main questions it aims to answer are: the difference of anal function 1 year after surgery type of study: clinical trial participant population: patients with low rectal cancer Participants will receive Parks operation of Bacon operation If there is a comparison group: Researchers will compare Parks and Bacon operation to see if the anal function 1 year after surgery is different.

Detailed description

objective: To compare the postoperative anal function of patients with ultra-low rectal cancer after Parks operation (colon anal anastomosis) and Bacon operation (colon anal pull-out anastomosis), which may provide clinical evidence for the improvement of anal function and quality of life. primary outcome: Low Anterior Resection Syndrome (LARS) score 1 year after surgery secondary outcomes: 1. LARS score at 3 months after surgery 2. LARS score at 6 months after surgery 3. Postoperative Quality of Life Score 4. The incidence of postoperative anastomotic complications
