A case of gastrojejunocolic fistula with steatohepatitis.

A man in his 30s, who had undergone retrocolic Billroth II reconstruction for perforated duodenal ulcer, presented with watery diarrhea for 2 years and suspected fatty liver. He was referred to our hospital for management of chronic diarrhea, weight loss, hepatopathy and hypoalbuminemia. Initial upper and lower gastrointestinal endoscopies were negative. Since a small bowel lesion was suspected, peroral single-balloon enteroscopy was performed, which identified feces-like residue near the Billroth II anastomotic site and a connection to the colon separate from the afferent and efferent loops. Transanal single-balloon enteroscopy identified a fistula between the gastrojejunal anastomosis and transverse colon, with the scope reaching the stomach transanally. Barium enema confirmed flow of contrast medium from the transverse colon through the fistula to the anastomotic site, allowing the diagnosis of gastrojejunocolic fistula. Liver biopsy showed relatively severe steatohepatitis (Brunt's classification: stage 2-3, grade 3). Resection of the anastomotic site and partial transverse colectomy were performed to remove the fistula, followed by Roux-en-Y reconstruction. Postoperatively, watery diarrhea resolved and the stools became normal. Hepatopathy and hypoproteinemia improved. One year later, liver biopsy showed marked improvement of steatosis. This case demonstrated marked improvement of both diarrhea/nutritional status and steatohepatitis after treatment of gastrojejunocolic fistula, suggesting that the fistula caused non-alcoholic steatohepatitis.

A polypoid gastric heterotopia of jejunum diagnosed by capsule endoscopy.

A 36-year-old lady presented with symptoms of intermittent small bowel obstruction caused by a polyp in the jejunum. CT scan and small bowel enema failed to demonstrate this polyp, and required a small bowel capsule endoscopy to finally reach a diagnosis. The objective of this report is to highlight the role of capsule endoscopy as a diagnostic tool in the small bowel pathology and to report a case of a polypoid gastric heterotopia of jejunum.

[Bleeding in digestive tract caused by jejunal angiodysplasia: complementary value of capsule endoscopy and double-balloon enteroscopy]. / Hemorragia digestiva oscura por angiodisplasia yeyunal: valor complementario de la cápsula endoscópica y la enteroscopia de doble balón.

We report the case of a 35-year-old male patient, with a history of six months of pallor and dyspnea associated with severe iron deficiency anemia and positive fecal occult blood tests. Endoscopy of the lower and upper gastrointestinal tract, and a small bowel follow-through were performed, but did not reveal the origin of the bledding. Later, a capsule endoscopy study were performed and detected an elevated area - not well defined - with active bleeding in the jejunal portion of the small bowel, for that reason we decided to complement the study with a double balloon enteroscopy, that allowed us to see more clearly the jejunal lesion: an elevated and ulcerated lesion; the area was marked with India ink to guide the surgeon. In the surgical intervention a resection of the involved jejunal segment was performed; the study of pathological anatomy established the diagnosis of jejunal angiodysplasia. We present this case of obscure gastrointestinal bleeding to emphasize the diagnostic utility of capsule endoscopy and double balloon enteroscopy.

[Multiple enterolithiasis, coexisting with bladder and gallbladder lithiasis, associated with colon adenocarcinoma]. / Enterolitiasis múltiple, coexistiendo con litiasis biliar y vesical, asociada a adenocarcinoma de colon.

Enteroliths are calculi primarily formed in the intestine. Enterolithiasis is a rare condition frequently associated with intestinal stasis. Usually it causes no symptoms in most cases, but it can be an important diagnostic clue in patients presenting intestinal occlusive symptoms. We report a case of multiple enterolithiasis, very infrequent pathology, coexisting with bladder and gall bladder lithiasis in a patient with colon adenocarcinoma. Diagnosis was made by X-rays and CT images. Calculi were analysed by several methods: chemical, infrared spectroscopy, stereoscopic microscopy and atomic emission spectroscopy; they showed that caluli are made up of organic material and whilokita (calcium and magnesium ortophosphate). No risk factors for lithogenesis were found in this patient excluding the intestinal stasis caused by intestinal narrowing as a result of adenocarcinoma. Genetic factors are suggested as main contributors to hyperlithogenesis observed in this patient. The physiopathological conditions were studied in depth and literature about this subject reviewed.

Isolated jejunal Crohn's disease in a young adult presenting as fever of unknown origin.

A 27-yr-old man was referred for fever, weight loss, fatigue, and occasional mild epimesogastric pain without diarrhea or vomiting. Laboratory tests were suggestive of an active inflammatory disease but serological, bacteriological, viral searches, markers of autoimmunity, and neoplasia were all negative. The following were also negative: ultrasonography; conventional x-rays; CT scans; esophagogastroduodenoscopy, pancolonoscopy with ileoscopy; cytohistology including duodenum and ileocolon. Empiric antibiotic regimens failed to control the temperature. Small bowel enema disclosed multiple proximal jejunal strictures. Jejunoscopy revealed erythema, friability, linear ulcerations, stenosis, and dilation in the proximal jejunum. Multiple directed biopsies showed inflammatory changes devoid of any specific features. The patient received steroid treatment and his temperature normalized. Six months later, he was readmitted on account of intestinal subocclusion that was managed conservatively. A few days later urgent laparotomy was performed with peritoneal lavage, repair of double perforated proximal jejunal ulcers, and stricturoplasty. Surgical jejunal biopsy confirmed the results of enteroscopic biopsies. The patient is presently without fever, in the absence of steroid treatment. There have been no reports of cryptogenic fever due to isolated jejunal Crohn's disease in the recent literature. Our patient's clinical picture resembled disease as seen in older children and adolescents, in whom it is a difficult diagnosis owing to the absence of diarrhea. In adults with Crohn's disease isolated jejunal involvement represents approximately 1% of cases. A thorough small bowel investigation is warranted in young adults with cryptogenic fever and low serum protein levels, even in the absence of major gastrointestinal complaints.

[Gastrointestinal hemorrhage secondary to heterotopic jejunal pancreas]. / Hemorragia digestiva secundaria a páncreas heterotópico yeyunal.

A case of heterotopic pancreas located in the small intestine is herewith presented. The 19-years male patient had been admitted three times since 1991 for an anemic syndrome secondary to melena. The origin of the hemorrhage was not determined with the studies performed (intestinal transit, opaque enema, esophagogastroscopy, colonoscopy and gammagraphy with technetium 99). On the last admission a vascular lesion low flow was observed on arteriography of the upper mesenteric artery on the mesenteric edge of the proximal jejunum. Following laparotomy a small tumor was found in the jejunum and 5 cm of the intestine including the tumor was resected. The anatomic pathologic results demonstrated a heterotopic pancreas.

[Churg-Strauss syndrome with rectal localization and exudative enteropathy]. / Syndrome de Churg et Strauss avec localisation rectale et entéropathie exsudative.

The authors report the case of a 61-year old patient with a Churg-Strauss syndrome revealed by abdominal pain. Investigations showed a diffuse inflammatory digestive tract involvement, documented by endoscopy associated with protein-losing enteropathy. Deep rectal biopsy revealed vasculitis in an otherwise macroscopically normal rectum. Faced with acute and life-threatening course of disease, emergency medical treatment with steroids and cyclophosphamide led to rapid regression of clinical, biological and radiological abnormalities.
