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.
