Objective：To analyze the cause of iatrogenic injuries during the laparoscopic procedures for patients with radical gastrec－tomy. Methods：Totally 113 laparoscopic surgery videos for radical gastrectomy were reviewed，which had been performed from Jan－uary 2012 to September 2013. Eleven iatrogenic injuries were revealed and related clinical data were analyzed further. Results：Among 11 iatrogenic injuries，1 patient had mesocolon injury，4 patients had spleen injuries，6 patients had blood vessels injuries including 1 patient with proper hepatic artery injury，1 patient with portal vein injury，2 patients with splenic vein injury，1 patient with short gas－tric artery injury，1 patient with upper pole splenic artery injury. All injuries above were caused by unclear dissection and lack of co－operation in operation. Conclusion：The main causes of iatrogenic injuries in laparoscopic surgery for radical gastrecotmy are unclear dissection and poor cooperation among surgeons.
