An unusual presentation of gastric fistula following peptic perforation repair: A case report

INTRODUCTION: Peptic perforation repair is a common stomach surgery. This surgery has not been associated with delayed onset gastrocutaneous fistula formation. However such a complication has been reported following a variety of other stomach surgeries. We are reporting this case as it is a rare complication. Also its diagnosis and management is challenging. CASE SUMMARY: We are presenting a case of peptic perforation repair where burst abdomen happened in the immediate post-operative period. The patient was put on conservative management. He responded well to it but his abdominal wound was not healing. After a wait of four months the wound was covered with a skin graft. The graft uptake was satisfactory but a discharging ulcer appeared on it. This condition persisted for one month. Finally a computed tomography Fistulogram (CT Fistulogram) was performed. It revealed an underlying complex gastric fistula. A repeat surgery was performed. CONCLUSION: A gastrocutaneous fistula diagnosed at sixth month following the peptic perforation repair and causing minimal discomfort to the patient is a rare presentation. The abdominal wound following the surgery was possibly not healing because of the underlying fistula.
