Inflammatory fibroid polyp (Vanek's tumor) causing double compound ileo-ileal intussusception in an adult patient, a case report.

The majority of the of small bowel intussusception causes are benign, and different types of benign tumors have been reported as the lead points of an intussusception. Among these, some studies have reported inflammatory fibroid polyp as a cause of small bowel intussusception. However, according to our knowledge this is the first case to be reported in Africa of an adult double compound intussusception due to an inflammatory fibroid polyp. A 32-year-old female presented with epigastric abdominal pain, nausea, vomiting and diarrhea for 2 weeks. Investigations revealed a small bowel obstruction due to intussusception, and exploratory laparotomy was planned. Inflammatory fibroid polyp causing this unique feature of double compound ileo-ileal intussusception should be observed in adult patients who presents with intestinal obstruction. A CT scan is the diagnostic modality of choice, and we think that the disease is the first of its kind to be reported in Africa. Double ileo-ileal intussusception is a rare cause of intestinal obstruction in adult patients. Laparotomy reviled an ileo-ileal intussusception. After manual reduction of this intussusception, another intussusception was observed and containing a polyp. A clear margin resection and end-to-end primary anastomosis were performed. The histopathological report established the diagnosis of Inflammatory Fibroid Polyp. After the procedure, the patient's condition improved well with no complications. This case report has been reported in line with the SCARE Criteria (Agha et al., 2020 [1]).
