Case Presentation: One patient received 3-port incisionless laparoscopic surgery for rectal cancer with a transrectal assistance by using a toothed oval clamp. Better direct vision and exposure could be acquired for performing laparoscopic surgical procedure, avoiding additional port inserted. Using this procedure, with strictly adhering to the principles of laparoscopic colectomy and oncological procedure, along with the specimen exteriorized via recta, transacted and a stapled anastomosis performed, no incision can be achieved at the end of an operation. The operative time was 180 minutes. The estimated blood loss in the course of an operation was 80 ml. The patient recovered quickly after surgery, with no post-operative pain and no incision. The patient was dischanged home on the 6th postoperative day. Conclusions: With a transrectal assistance by using a toothed oval clamp, 3-port laparoscopic surgery for rectal cancer could be achieved without no incision at the end of the operation, the same as NOTES. It is enormously advantageous to the patient and suitable for application in developing countries, especially in a rural area.展开更多
