title: Enterocutaneous fistula: a complication of posterior iliac bone graft harvesting not previously described.
abstract: A case of enterocutaneous fistula at the donor site is presented. A patient underwent posterior C5-C6 wire fusion with autologous bone graft taken from the posterior superior iliac crest for degenerative C5-C6 spondylolisthesis. The tip of the osteotome slipped anteriorly during the procurement but neither neurovascular nor peritoneal injury were observed. Spillage of formed faecal material was observed from the donor site on the 12th postoperative day. Fistulogram showed an enterocutaneous fistula to descending colon. The fistula closed spontaneously in a week. Enterocutaneous fistula after bone harvesting has never been reported in the literature as far as we know. Congenital malformations and acquired causes may create a vulnerable peritoneal area. Small bowel or descending colon may show a close relationship or even an adhesion to peritoneum in the presence of local peritonitis. A small lesion in this area may play a role in the occurrence of a fistula, and a low flow pseudofistulous tract may appear. The thermal injury and possible ischaemic necrosis due to cauterisation may be predisposing factors in the aetiology of this kind of fistula. The lack of foreign material and spontaneous closure were against an infectious origin. The aims of this report are to present and analyse the reasons of this complication, not previously described.
