In recent 11 years, 5 cases of severe high voltage electrical burn with intestinal perforations were successfully treated. They showed obvious whole layer necrosis of abdominal wall, exudation, intestinal prolapse and peritonitis. On the basis of antishock therapy and protection of renal function, acute laparotomy was done early. Resection of the small intestine with necrosis and perforation and end-to-end anastomosis were done in 4 cases (5 regions). Colon resection and colostomy were done in 2 cases, and immediate end-to-end anastomosis in 2 cases. Bowel segment with external fistulae was left in 1 case (2 regions). If the abdominal wall defect could not be sutured directly, skin grafting on the residual tissue and omentum may be temporarily effective. And myocutaneous pedicle flap should be repaired secondarily. After operation, parenteral nutrition and anti-infection are important for patient recovery. No complication occurred in this group.
