The Effect of Different Reconstruction Methods on Anterior Resection Syndrome (TEDRMARS)

Study Description
Brief Summary:
The incidence of prerectal resection syndrome (LARS) after middle and low rectal cancer surgery is as high as 70%, which seriously affects the quality of life of patients. Studies have shown that colon pouch can reduce and alleviate LARS symptoms. However, most previous studies focused on open surgery, and the evaluation index lacked objectivity. Therefore, in the context of minimally invasive rectal cancer surgery, it is necessary to re-evaluate the value of improved surgical methods for the prevention of LARS, so as to improve the quality of life of patients.

Condition or disease Intervention/treatment Phase
Rectal Cancer Low Anterior Resection Syndrome Procedure: transverse coloplasty pouch Not Applicable

Detailed Description:
The incidence of prerectal resection syndrome (LARS) after middle and low rectal cancer surgery is as high as 70%, which seriously affects the quality of life of patients. LARS may be related to the injury of anal internal sphincter, anal sensory nerve injury, defecation reflex pathway injury, changes in anorectal Angle and rectum sigmoid Angle, changes in new rectal sensory function and compliance, and changes in dynamics,etc. After AR surgery, the rectum loses its good compliance and the storage capacity is reduced, which is one of the important reasons for the increased frequency and urgency of defecation.Therefore, on the basis of traditional colon-rectum (or anal canal) end-to-end anastomosis, "J" shaped pouch anastomosis, end-to-end anastomosis, coloplasty and other special anastomosis methods were performed. Meanwhile, for the lack of objective evaluation index, the results were not credible. The LARS score was first published in 2012,and has been validated, evaluated, or used as an outcome measure in more than 30 published scientific papers. Further more,laparoscopic surgery is widely used in gastrointestinal surgery. Herein, current randomized controlled trial comparing coloplasty with straight colorectal anastomosis in LARS in order to guide clinical practise was conducted.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 138 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Prevention
Official Title: The Effect of Different Reconstruction Methods in Laparoscopic Anterior Rectal Resection on Postoperative Anterior Resection Syndrome:a Randomized Controlled Trial
Estimated Study Start Date : September 1, 2019
Estimated Primary Completion Date : May 1, 2022
Estimated Study Completion Date : September 1, 2022
Arms and Interventions
Arm Intervention/treatment
Experimental: coloplasty(CP)
After purse-string suture and ligation of the head of the stapler at the colonic end, 5cm away from the colonic end, 5cm longitudinal incision was made to the proximal end of the teniae coli in the anterior wall of the colon, transverse suture was performed, and the plasmomuscular layer was embedded, then end to end colon-rectum (or anal canal) anastomosis was performed
Procedure: transverse coloplasty pouch
a transverse coloplasty pouch was performed before end to end colon-rectum (or anal canal) anastomosis

No Intervention: straight colorectal anastomosis (SCA)
End to end colon-rectum (or anal canal) anastomosis was performed routinely
