Successful Re-ileostomy Using Skin Flap Formation Techniques.
Cureus
December 2024
Department of Surgery, Kishiwada Tokushukai Hospital, Kishiwada, JPN.
A 61-year-old woman underwent an emergent operation with sigmoid colon cancer resection, colostomy, and ileostomy on colon perforation. The low ileostoma, caused by intra-abdominal bad conditions, had irritated the surrounding skin after surgery, intermittently forcing the patient to fast for a certain period. Six months after the operation, under the judgment that re-ileostomy, essential for hospital discharge, seemed very difficult through another laparotomy, we attempted to make the ileostoma higher not with pulling the ileum from the abdomen but with lowering the surrounding skin using skin flap formation techniques.

After initial gynaecological assessment, further clinical radiological investigations, computerized tomography imaging showed that the intraluminal part of the radiological foreign body was seen to be possibly perforating the sigmoid colon after having migrated.
