Enhanced recovery after surgery (ERAS) has been widely used in the world for near 20 years, which should be considered as the milestone of modern medicine advancement, changing the routine perioperative principle, accelerating the recovery speed following operation, minimizing the postoperative pain, and saving the medical resources. Despite the remarkable advance, the quality and application of ERAS in the west China needs further improvement if compared with international level or even some domestic hospitals. The postoperative hospital stay in west China is much longer than the reported 3 to 5 days according to published references. Several suggestions can be help: (1) Based on the published consensus and the successful experiences of ERAS in colorectal surgery, the medical institution should make great effort to extend this technique to change the profound traditional idea in medical staffs and patients. (2) The medical administrations should take the application of ERAS as a key performance index and annual work plan in hospital. (3) Multiple disciplinary team including anesthetist, surgeon, dietitian, and nurses is essential for hospital to promote the quality of ERAS. Undoubtedly, ERAS is going to be the conventional medical care in the western area of China. We may look forward to seeing more researches from western China to update the ERAS consensus.

Robotic-assisted transanal total mesorectal excision (R-TaTME) has unique advantage in low rectal cancer. Single incision plus oneport (SIPOP) laparoscopic operation can synchronously cooperate with robotic-assisted transanal operation, in order to the difficulty of operation, improve the quality of operation and shorten the time of operation. A retrospective analysis was conducted on the clinical and pathological data of one patient who underwent SIPOP synchronously combined with R-TaTME + sigmoid-anal anastomosis + ileostomy at the Department of General Surgery, Army Characteristic Medical Center on September 11, 2019. This 71-year-old patient was male with body mass index of 24.08 kg/m 2 and received preoperative chemotherapy. Rectal adenocarcinoma was confirmed by colonoscopy biopsy, and distance from tumor lower edge to anal verge was 3 cm. MRI indicated T2N1 stage. The operation was completed successfully, and the transabdominal and robotic transanal surgery totaled 117 minutes, with 15 minutes for the robotic transanal preparation step. There was about 20 ml of intraoperative blood loss and no blood transfusion was performed. The patient was discharged 6 days after operation. No intraoperative or postoperative complications occurred. The postoperative TNM staging was stage I (pyT2N0cM0). No recurrence or metastasis was found at postoperative 7 month. It is a safe, effective and feasible technique for patients with low rectal cancer.
