Introduction: Total mesorectal transanal excision is an alternative in the treatment of rectal cancer. Transluminal endoscopic surgery through natural orifices, using the rectum as an access in colorectal surgery is better tolerated than other approaches. Objective: To describe the advantages of transanal approach for rectal cancer. Materials and methods: We report the case of a total excision of the mesorectum via transanal approach in a 57 year-old male with a tumor located 4 cm from the anal verge. Colonoscopy and magnetic resonance imaging protocol was followed. CT of the abdomen, pelvis and chest were negative for metastatic findings. Neoadjuvant chemotherapy and radiotherapy were administered. We practiced a transanal time and an abdominal time and met at the tumor site. Results: The total operative time was 240 minutes, the dietary intake was resumed 12 hours after surgery, and the ileostomy was functional 24 hours after surgery. He was discharged five days after surgery without complications, with a pain scale score of 2/10. Pathology reported a complete mesorrectal dissection classified as PT2N1 pT2N1. Conclusion: The best indication for this approach is lower third (less than 6 cm from the anal margin) located tumors, as this surgical approach gives us solutions to problems posed by conventional laparoscopic surgery (section of the rectum with enough distal margin, pelvic dissection), especially in patients with unfavorable characteristics for laparoscopic surgery (male, obese, narrow pelvis and bulky tumors).
