Conditions
Summary
The investigators propose to use flexible endoscopy combined with transanal total mesorectal resection to further reduce anal injury.
Eligibility
Inclusion Criteria4
- Age between 18 and 80 years old
- Confirmed rectal adenocarcinoma cancer pathologically
- tumor location ≦ 12 cm from the anal margin
- Willing and able to provide written informed consent for participation in this study
Exclusion Criteria7
- distant metastasis before surgery
- more than one colorectal tumor at diagnosis
- familial adenomatous polyposis
- recurrent rectal cancer
- undergo transanal minimally invasive surgery
- undergo palliative treatment
- undergo emergency surgery
Interventions
Endoscopic pursestring suture (EPSS) was performed at the distance from 1cm to the inferior edge of the tumor by a double-channel flexible colonoscope. An endoloop was inserted through one channel. Meanwhile, the endoclips was inserted through the other channel one by one to fix the endoloop around the rectal wall. And then the endoloop was tightened slowly. After completing the routine lavage lumen, a full-thickness, circumferential dissection was performed by flexible colonoscope following taTME surgical principle until it converged with the laparoscopy group.
