Regardless of the advances in surgical techniques, parastomal hernia is still an inevitable complication for many patients with low rectal cancer undergoing abdominal perineal resection (APR). Extraperitoneal colostomy (EPC) seems to be a effective method to reduce the risk of parastomal hernia. We propose a new approach to simplify and standardize laparoscopic EPC to make this operation easy to perform. We used the technique of laparoscopic TEP groin hernia repair to produce an extraperitoneal tunnel, which can not only facilitate precise visualization of the extraperitoneal tunnel but also utilize the intact posterior rectus abdominis sheath as biologic materials to maintain soft-tissue augmentation, with a satisfactory result. With laparoscopy, we can create adequate space without insufficient dissection of the extraperitoneal tunnel while avoiding damage to the retrorectus sheath. At the time of writing, we had performed this method in four patients, without any complications. This technique is effective at preventing parastomal hernia without extra costs.
