A boy with duodenocolic fistula mimicking functional gastrointestinal disorder

Congenital enterocolic fistula discovered by jejunoscopy

“…1 Unlike our case, in pathological conditions there is usually presence of dense adhesions or local lymphadenopathy around fistula seen during surgery. 3 Surgical resection reversed all the symptoms with catch-up normal growth and puberty.…”

“…Okada et al report an adolescent with duodenocolic fistula secondary to a congenital colonic diverticular disease, erroneously diagnosed earlier as functional gastrointestinal disorder. 3 Symptoms of entero-colic fistula are abdominal pain, gaseous distension, nausea, vomiting, diarrhea, steatorrhea, loss of weight and growth failure. 1 Abnormal entry of bacterial flora causes SIBO, malabsorption and growth failure by multiple mechanisms which include deconjugation of bile acids causing steatorrhea, mucosal inflammation causing partial villous atrophy, increase in intestinal permeability and competition for nutrients.…”

Giant diverticulum of the transverse colon mimicking gastrocolic fistula: A case report

“…The most common physical findings in GCF are abdominal tenderness and distention, and palpable masses that may also be reported in GCD patients. In a study by Okada et al, the patient was found to have a diverticulum located near the fistula, accompanied by evidence of H. pylori infection [ 3 ]. One of the causes of fistula is diverticulitis-related colonic diverticulum perforation with the diverticulum near the fistula was found to firmly adhere to the fistula wall [ 10 ].…”

“…The transverse colonic diverticulum is thought to be closely related to gastrocolic fistula (GCF). Clinical features and radiological findings often exhibit similar symptoms and signs [ 3 ]. This research work has been reported in line with the SCARE checklist [ 4 ].…”
