    Abstract:
    BACKGROUND: Transanal total mesorectal excision (TaTME) avoids the difficulty of laparoscopic dissection of the lower part of the rectum. The need for stoma is associated with many stoma-related complications. The objective was to compare TaTME with immediate coloanal anastomosis and protective ileostomy (TaTME-IA) versus Turnbull-Cutait delayed coloanal anastomosis (TaTME-TC). METHODS: A retrospective cohort study included patients with low rectal cancer at least 1 cm above the top of the anal sphincter. Patients had either TaTME-IA or TaTME-TC. Primary outcome measures were anastomotic and stoma-related complications. Secondary outcomes included rate of permanent stomas, local recurrence, continence, and quality of life (QOL). RESULTS: TaTME-IA was done in 25 patients versus 20 who had TaTME-TC. TaTME-IA had significantly longer mean operative time (p = 0.04) and shorter length of stay (LOS) (4.5 vs. 11.4 days; p = 0.0001) compared to TaTME-TC. Anastomotic leak was reported in two patients of TaTME-IA versus one patient of TaTME-TC (p = 0.77). Anastomotic stenosis was reported in one patient in each group. No significant difference between groups as regard continence, local recurrence, and QOL. CONCLUSION: TaTME-TC is a safe option that can be offered for patients with low rectal cancer who refuse or are not amenable to a temporary stoma. Anastomotic complications were similar in both groups. LOS was much longer in TaTME-TC, however, it avoids stoma complications. Both groups had similar functional oncologic outcomes and QOL.
