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

INTRODUCTION AND IMPORTANCE: 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. CASE REPORT: 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. CLINICAL DISCUSSION: 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. CONCLUSIONS: Double ileo-ileal intussusception is a rare cause of intestinal obstruction in adult patients. INTERVENTIONS AND OUTCOME: 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. METHODS: This case report has been reported in line with the SCARE Criteria (Agha et al., 2020 [1]).

Abdominal cocoon syndrome, a case report of a rare disease entity causing intestinal obstruction.

INTRODUCTION AND IMPORTANCE: Abdominal cocoon syndrome is a rare condition characterized by small bowel encapsulation by a fibrous membrane or a cocoon-like sac. It is an uncommon cause of intestinal obstruction. Less than 300 cases have been reported from all over the world. This is the first case of such a disease entity to be reported from Sudan. CASE PRESENTATION: A young female patient, presented with features of intestinal obstruction that was managed conservatively. Failure of the conservative management has warranted a laparotomy. CLINICAL FINDINGS AND INVESTIGATIONS: Her features were suggestive of intestinal obstruction that was confirmed radiologically. INTERVENTIONS AND OUTCOME: Laparotomy revealed a membrane-like fibrous material and extensive multiple loops adhesions, findings consistent with primary sclerosing encapsulating peritonitis (PSEP), also known as abdominal cocoon's disease. The membrane was excised and adhesiolysis was done. Intestinal obstruction was relieved after surgery and the patient showed good outcome. CONCLUSIONS: Abdominal cocoon syndrome is a rare cause of intestinal obstruction. RELEVANCE AND IMPACT: The takeaway lesson from this case would be that the PSEP should be sought in any patient with no clear cause for obstruction can be identified. A contrast-enhanced CT scan is the diagnostic modality of choice. Finally, we think that the disease is underreported from Africa and more efforts should be carried out to increase patients' access to healthcare especially in rural areas with no access to hospitals in order to bring more cases to light. This case report has been reported in line with the SCARE Criteria (Agha et al., 2020 [17]).
