Perforated gangrenous ileo-colic intussusception in a 9 month old Nigerian infant presenting at a private hospital: A case report

INTRODUCTION: Intussusception is the process of invagination of a bowel segment into the adjoining intestinal lumen which may cause bowel obstruction and gangrene. It commonly occurs in infants at a mean age of 9-months with male preponderance. The condition has excellent prognosis if diagnosis is made early and appropriate treatment commenced and mortality rate from intussusception in children can be less than 1%. However, if diagnosis or treatments are delayed it can be fatal in a few days. PRESENTATION OF CASE: We present a case of Ileo-colic perforated ileum due to delayed diagnosis. It was initially misdiagnosed as gastroenteritis at another hospital. The infant was resuscitated with intravenous fluid and had laparotomy. A signed consent was obtained before the surgery and media consent was signed for publication. A gangrenous terminal ileum was resected and ileo-colic anastomosis was done. Post-operative course was uncomplicated and the patient was discharged after 5days. DISCUSSION: The index case presented late with complication of gangrene and perforation because it was first managed as a case of gastroenteritis. Gastroenteritis is among the various differential diagnosis of intussusception. Complications have been reported to increase numbers of surgical treatment and sometimes mortality, but rarely occur with good diagnostic acumen. CONCLUSION: We conclude that high clinical suspicion, interaction with senior surgeons and regular use of ultrasound in infants with gastrointestinal symptoms will aid diagnosis. Although surgery was performed in the index case, non-surgical reduction is a very efficient treatment modality in uncomplicated cases.
