Objective To explore the prevention and management of surgieal complications in Miles operation.Methods Retrospectively analyzed the main complications appeared in 176 patients of Miles operation.Results There was the eolostomy-related complications in 19 cases.Presacral venous plexus hemorrhage in 4 cases.Intestinal obstruction in 10 cases.Wound infection of perineum in 12 eases.Lesion of urinary tract in 1 case.The common complication rate of Miles operation was 26.1%.Conclusion Mastering operation skill and adherence to sound snrgical principles is the key to prevent and to decrease intra-postoperative complication.

Objective To evaluation the clinical implemented and primary experience of TME combined the double-stapling technique in low rectal carcinoma anus-preserving resection. Methods 22 cases of low rectal carcinoma (the distance between the inferior verge of rectal turnout and the anal verge were 4～7cm) were operated by TME combined the double-stapling technique. Results All of the 22 cases of TME combined double-stapling procedure were successful without operative mortality. Correlative complications including anastomotic leakage (3 cases), anastomotic stenosis (1 case). Temporary completely defunctioning loop colostomy 4 cases. Conclusions TME combined the double-stapling technique in low rectal carcinoma anus-preserving resection is feasibility and the tumour pathology and clinical stage should be considered. Mastering expert operation skill and adherence to sound surgical priciples is the key to prevent and to decrease postoperative complication.
