Recruiting
Conditions
Rectal Cancer
Interventions
Procedure: Virtual ileostomy
Registration Number
NCT06633133
Lead Sponsor
Daping Hospital and the Research Institute of Surgery of the Third Military Medical University
Brief Summary

The goal of this clinical trial is to learn to compare the safety and efficacy of virtual ileostomy versus diverting ileostomy in patients undergoing sphincter-saving surgery for rectal cancer. The main questions it aims to answer are:

* Is the virtual ileostomy a safe and effective alternative to the ileostomy?

* Is it scientifically reasonable to perform diverting ileostomy intraoperatively? Researchers will compare virtual ileostomy to diverting ileostomy to see if the virtual ileostomy works to reduce rates of stoma.

Participants will:

* Performing diverting ileostomy or virtual ileostomy undergoing sphincter-saving surgery for rectal cancer

* Continuous follow-up of their complications after the first surgery

Postoperative hospitalization days(Initial and all subsequent hospitalizations)Through study completion, an average of 5 year

Patients in the virtual stoma group who did not have a second surgery due to complications recorded days of postoperative hospitalization after low anterior resection for rectal cancer, if the virtual stoma group required bedside or secondary surgery for diverting ileostomy due to complications and all patients in the diverting ileostomy group required reoperation for stoma reversal, record days of postoperative hospitalization due to complications and/or reoperation since the data of low anterior resection for rectal cancer.

The number of hospitalizations(Initial and all subsequent hospitalizations)Through study completion, an average of 5 year

Patients in the virtual stoma group who did not have a second surgery due to complications recorded the number of hospitalizations after low anterior resection for rectal cancer. If the virtual stoma group required bedside or secondary surgery for diverting ileostomy due to complications and all patients in the diverting ileostomy group required reoperation for stoma reversal, record the number of hospitalization due to complications and/or reoperation since the data of low anterior resection for rectal cancer.

Duration of bearing the stoma (months)Through study completion, an average of 5 year

If the virtual stoma group required bedside or secondary surgery for diverting ileostomy due to complications and all patients in the diverting ileostomy group required reoperation for stoma reversal, record the duration of bearing the stoma since the data of surgery of diverting ileostomy.

Total hospitalization costs(Initial and all subsequent hospitalizations)Through study completion, an average of 5 year

The defecation function of all postoperative patients. Wexner score range is 0-20 points, with 0 points indicating normal and 20 points indicating complete incontinence.

Quality of life(EORTC QLQ-C30)Through study completion, an average of 5 year

The quality of life of all patients was assessed using relevant scales\[EORTC (The European Organization for Reasearch and Treatment of Cancer) QLQ-C30(Quality of Life Questionnare-Core 30)\]. The EORTC QLQ-C30 (V3. O) consists of 30 entries, which can be divided into 15 domains, including 5 functional domains (physical, role, cognitive, emotional, and social functions), 3 symptom domains (fatigue, pain, nausea, and vomiting), 1 overall health/quality of life domain, and 6 individual entries (each as a domain). EORTC QLQ-C30 has a total of 30 entries. Among them, entries 29 and 30 are divided into seven levels, ranging from 1 to 7 points based on their answer options; the other entries are divided into 4 levels: none(1 point), a little(2 points), more(3 points), many(4 points). The QLQ-C30 scale is reversed except for items 29 and 30 (the higher the value, the worse the quality of life).

Low anterior resection syndrome for rectal cancerThrough study completion, an average of 5 year

The investigators use LARS scale to evaluate the patient's defecation function.The LARS rating scale consists of 5 questions: voiding incontinence, fluid voiding incontinence, frequency of voiding, voiding aggregation, and voiding urgency. 0-20 is classified as no LARS, 21-29 is classified as mild LARS, 30-42 is classified as severe LARS.

Quality of life for fecal incontinenceThrough study completion, an average of 5 year

The Fecal Incontinence Quality of Life Scale (FIQL) is mainly used to evaluate the quality of life of patients with fecal incontinence. It includes four main aspects: lifestyle changes, psychological coping/behavioral limitations, depression/self-perception, and social embarrassment. The FIQL is analyzed as a total score; the higher the patient's score, the higher the patient's quality of life.
