Abstract

Background: We compared triangulating anastomosis (TRI) with functional end-to-end anastomosis (FEEA) in terms of patient demographics, clinicopathological features, and short- and long-term outcomes in this study. Methods: From November 2005 to May 2016, 315 patients with transverse colon cancer underwent laparoscopic resection. TRI was performed in 62 patients and FEEA in 253 patients. Patients with another concomitant cancer, who received neoadjuvant chemotherapy, and/or who underwent another operation at the same time were excluded. Results: The patients’ backgrounds were comparable in each group. Transverse colectomy was selected more frequently in TRI and right hemicolectomy in FEEA. The operation time was shorter in TRI. The rate of anastomotic leakage was comparable (1.6% in TRI vs. 0.8% in FEEA). Stricture was more common in TRI (8.1% vs. 0%) and bleeding was more common in FEEA (1.6% vs. 10.6%). The rate of long-term complications was comparable in each group. Overall survival of stage 0–III patients was comparable in each group (94.7% in TRI vs. 93.7% in FEEA). 5-year disease-free survival of stage 0–III, stage II, and stage III patients was also comparable in each group (94.8% vs. 93.0%, 100% vs. 92.1%, and 80.3% vs. 79.2% in TRI and FEEA, respectively). Conclusion: The short- and long-term outcome rates were acceptable in both groups. Specific attempts to prevent complications are required for each anastomotic procedure.
