Abstract
When a passenger is thrown from a moving personal watercraft (PWC), the jet propulsion can cause a characteristic recto-vaginal injury. Though this is rare among the PWC related injuries, its damage morphology is very complicated and difficult to treat ; and sometimes it can be fatal. Case1 : A 25-year-old woman was thrown backward from a moving PWC. The patient had profound perineal bleeding and was transferred to our hospital. Anal laceration and rectal injuries were noted. One of the rectal injuries had reached above the peritoneal reflection and a diverting colostomy was performed. The patient was discharged from our hospital on 12th hospital day. The closure of her colostomy has not been completed. Case 2 : A 27-year-old woman was thrown backward from a moving PWC. Multiple recto-vaginal injuries and profound bleeding were noted. Her rectal injury was controllable with a diverting colostomy, however the vaginal bleeding originating from the fornix was quite difficult to control. Though the patient once lapsed into severe hemorrhagic shock, the bleeding was successfully controlled with a trans-catheter arterial embolization. The patient was transferred to another hospital on 35th hospital day.
