We performed transverse coloplasty in 33 patients with rectal cancer who had undergone an anal function preservation operation in which the anastomotic site was within 1 cm of the dentate line (ultra-low anterior resection) and evaluated its effectiveness in controlling the patients' defecatory function. The average daily defecation frequency 1, 6, and 12 months postoperatively was 7.8, 5, and 3.6 times daily following straight colorectal reconstruction (the anastomotic site was more than 5 cm from the dentate line) and 7.5, 3.5, and 2.4 times daily following transverse coloplasty, respectively. Concerning postoperative complications, anastomotic leakage, soiling, and constipation were observed in 1, 1, and 1 cases, respectively. Transverse coloplasty can be performed in a short time, and it is considered a safe and useful method to manage defecatory | lld:pubmed |
