Brief Summary:
The purpose of this study is evaluation of the safety and the efficacy of transanal total mesorectal excision.

Condition or disease Intervention/treatment Phase
Rectal Cancer Procedure: Transanal total mesorectal excision Not Applicable

Detailed Description:
Subjects will have their rectal cancer removed using a technique combining surgery through the anus and standard laparoscopy. Transanal visualization will be using endoscopy. At the end of the procedure, the rectum will be removed though the anus or ileostomy formation site, the bowel will be re-connected to the anus, and a temporary diverting stoma will be created, which is standard of care following surgery for this type of cancer.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 12 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Pilot Study for the Evaluation of the Safety and the Efficacy of Transanal Total Mesorectal Excision
Study Start Date : September 2013
Actual Primary Completion Date : August 2014
Actual Study Completion Date : August 2014

Arm Intervention/treatment
Experimental: Transanal total mesorectal excision
Laparoscopy-assisted transanal total mesorectal excision
Procedure: Transanal total mesorectal excision
Laparoscopy-assisted transanal total mesorectal excision

Primary Outcome Measures :
  1. Total Mesorectal Excision(TME) quality [ Time Frame: 1-5 years ]

    The quality of the mesorectum was determined using pathology reports and scored using three grades:

    • Complete: intact mesorectum with only minor irregularities of a smooth mesorectal surface. No defect is deeper than 5 mm, and there is no coning toward the distal margin of the specimen. There is a smooth circumferential resection margin on slicing.
    • Nearly complete: moderate bulk to the mesorectum, but irregularity of the mesorectal surface. Moderate coning of the specimen is allowed. At no site is the muscularis propria visible, with the exception of the insertion of the levator muscles.
    • Incomplete: little bulk to mesorectum with defects down onto muscularis propria and/or very irregular circumferential resection margin.

Secondary Outcome Measures :
  1. 30-day postoperative complications, No. of harvested LN [ Time Frame: 1-5 years ]

Other Outcome Measures:
  1. Oncologic outcome(2-year local recurrence free survival, 5-year survival) [ Time Frame: 1-5 years ]
