Core Tip
Core tip: Local excision was regarded as the conversional treatment for early stage rectal neoplasia. Recent evidence, however, revealed certain disadvantages. Minimally invasive surgery has been adopted in treating rectal cancer. This study was the first well-documented retrospective trail demonstrating the safety and feasibility of trans-anal minimally invasive surgery. Short-term follow-up showed no serious post-operative complications (over grade IIIa by CD classification), meanwhile, lateral resection margin should be evaluated pathologically and surgeons proficient for laparoscopic surgery would be confident over the learning curve regarding 10 cases.
