RESUMO
Primary eosinophilic gastrointestinal disorders include a spectrum of inflammatory chronic diseases in which eosinophils infiltrate the gut in the absence of known causes of such tissue eosinophilia. They may affect any area of the gastrointestinal tract although exclusive colonic disease is exceptional. Due to their low prevalence these disorders are not usually taken into account when making a differential diagnosis in a patient with chronic diarrhea, which is the reason why in many cases the diagnosis can take many years. We describe the case of a patient with well-controlled celiac disease and chronic diarrhea of indeterminate origin. The final diagnosis was eosinophilic colitis. A complete response was obtained when she was treated with oral budesonide. Nowadays she remains asymptomatic.

INTRODUCTION: accurate preoperative localization of colorectal cancer (CRC) is very important, with a wide range of published error rates. AIMS: to determine accuracy of endoscopic localization of CRC in comparison with preoperative computed tomography (CT). To analyse variables that could be associated with a wrong endoscopic localization. PATIENTS AND METHODS: endoscopic and CT localization of a series of CRC without previous surgery were reviewed. We studied the concordance between endoscopic and radiologic localization against operative findings comparing accuracy of endoscopy and CT. We analysed the frequency of wrong endoscopic diagnoses with regard to a series of patient, endoscopy and tumor variables. RESULTS: two hundred thirty seven CRC in 223 patients were studied. Concordance with surgical localization was: colonoscopy = 0.87 and CT = 0.69. Endoscopic localization accuracy was:91.1%; CT: 76.2%: p = 0.00001; OR = 3.22 (1.82-5.72). Obstructive cancer presented a higher rate of wrong localization: 18 vs. 5.7% in non-obstructive tumors (p = 0.0034; OR = 3.65 (1.35-9.96). Endoscopic localization mistakes varied depending on tumor location, being more frequent in descending colon: 36.3%, p = 0.014; OR = 6.23 (1.38-26.87) and cecum: 23.1%, p = 0.007; OR = 3.92 (1.20-12.43). CONCLUSIONS: endoscopic accuracy for CRC localization was very high and significantly better than CT accuracy. Obstructive tumor and those located in the descending colon or cecum wereassociated with a significant increase of the error risk of CRC endoscopic localization.

Cholecystocolic fistula is an uncommon biliary-enteric fistula with a variable clinical presentation that usually appears as a rare complication of gallstone disease. It can present with abdominal pain, nausea, weight loss, diarrhoea with or without associated steatorrhea, and dyspeptic symptoms. Rare cases have been reported with lower gastrointestinal haemorrhage and even with a gallstone ileous. The most useful techniques for diagnosis are CT, barium studies, and ERCP. We report a case of a cholecistocolic fistula in an elderly woman with multiple medical comorbidities that presented as lower gastrointestinal bleeding. She was explored with colonoscopy, abdominal CT and barium enema. She required a total of 4 units of whole blood and because of her comorbidities a decision was made not to proceed with invasive treatment. She had a good evolution and was asymptomatic two months later.
