The gastrojejunocolic fistula represents a clinical entity that occurs very rarely following gastro-jejunal anastomoses and manifests itself clinically and paraclinically by a severe malabsorption syndrome. The results of the physiopathological approach may be summed up as follows: reduced level of seric proteins, fluid and electrolytic depletion, deficiencies in the absorption of the vitamins soluble in fats and water, which may all vary from mildness to severeness, depending on the flow rate of the fistula. Most often, the diagnosis is set by performing barium enema, which is positive for all cases, whereas the barium passage is less efficient, enabling diagnosis in only 33% of the cases. The radiological image may be reduced on principle to one single sign: the abnormal fistulous trajectory (barium passes from the stomach directly into the colon or the enema fills the gastric lumen). It is recommended that surgical treatment be performed in a single stage, by resecting the entire fistula and re-establishing the gastro-jejunal and colic continuity. We report a case of gastrojejunocolic fistula in a patient that underwent 2/3 gastric resection for gastric ulcer 9 years ago.

Amyloidosis is a unique metabolic storage disease that affects the gastrointestinal tract but rarely causes severe symptoms. We describe the case of a 51-year-old woman presenting with chronic small bowel diarrhoea and malabsorption. Barium contrast studies and enteroscopy revealed a coarse mucosal pattern and thickening of the jejunal and proximal ileal folds. Histological examination revealed massive deposits of amyloid in thejejunal wall. No predisposing factor was found and there were no other sites of deposition. This is a rare case report of primary selective small intestinal amyloidosis manifesting as the malabsorption syndrome.

Cholecystocolonic fistula (CF) is an uncommon type of internal biliary-enteric fistulas, which comprise rare complications of cholelithiasis and acute cholecystitis, with a prevalence of about 2% of all biliary tree diseases. We report a case of a spontaneous CF in a 75-year-old diabetic male admitted to hospital for the investigation of chronic watery diarrhea and weight loss. Massive pneumobilia demonstrated on abdominal ultrasound and computerized tomography, along with chronic, bile acid-induced diarrhea and a prolonged prothrombin time due to vitamin K malabsorption, led to the clinical suspicion of the fistula. Despite further investigation with barium enema and magnetic resonance cholangio-pancreatography, diagnosis of the fistulous tract between the gallbladder and the hepatic flexure of the colon could not be established preoperatively. Open cholecystectomy with fistula resection and exploration of the common bile duct was the preferred treatment of choice, resulting in an excellent postoperative clinical course. The incidence of biliary-enteric fistulas is expected to increase due to the parallel increase of iatrogenic interventions to the biliary tree with the use of endoscopic retrograde cholangio-pancreatography and the increased rate of cholecystectomies performed. Taking into account that advanced imaging techniques fail to demonstrate the fistulas tract in half of the cases, and that CFs usually present with non-specific symptoms, our report could assist physicians to keep a high index of clinical suspicion for an early and valid diagnosis of a CF.

Celiac disease is now recognized as a common disease, occurring in about one in every 200 Americans. However, less than 10% of cases are currently diagnosed, with a diagnostic delay of more than 10 years from onset of symptoms. In the past, barium examination of the small bowel demonstrated a pattern of abnormal findings caused by the pathophysiologic changes induced by malabsorption, thus leading to diagnosis of celiac disease and other diseases of malabsorption. Although not specific, that pattern prompted further patient evaluation. The number of barium examinations performed and the skill necessary to interpret their results are both in decline. Abdominal pain in celiac disease is a common early complaint that often leads to computed tomography (CT). Improved CT resolution now permits better depiction of the small bowel, colon, and mesenteric lymph nodes, all of which are affected by celiac disease. Detection of celiac disease with CT will allow treatment to be initiated to prevent the significant morbidity and increased mortality associated with a delay in diagnosis. The abnormal CT findings seen over the past decade during review of more than 200 cases of celiac disease demonstrate that CT depicts more features of celiac disease than did barium examination. Pattern recognition for the diagnosis of small bowel diseases that create structural changes in the bowel wall is well accepted. Because it demonstrates features of celiac disease not detected with barium examination, CT may be more sensitive than barium examination for diagnosis of this disease.

Benign duodenocolic fistula (DCF), known as a fistula between the duodenum and colon with or without cecum of nonmalignant origin, is an unusual complication of different gastrointestinal diseases. The present paper records a case in which the patient presented with chronic diarrhea, abdominal pain, weight loss as well as having a history of gastric ulcer. Most frequently the condition presents with signs of malabsorption such as weight loss and diarrhea, but other symptoms include nausea, vomiting (sometimes with fecal), and abdominal pain. Gastrointestinal inflammatory conditions are the usual causes. The most common ones are perforated duodenal ulcer and Crohn's disease. Barium enemas are usually diagnostic. Treatment consists of excising the fistula and repairing the duodenal and colonic defects. Closure of the fistula provides quick relief.
