Chronic diarrhea as a result of colonic fistulas -two case reports with different origin. When it comes to chronic diarrhea symptom, the first thing one thinks of is never a surgical cause, but an infectious disease. The aim of this paper is to show 2 different cases of chronic diarrhea, resulting from benign surgical causes - colonic fistula. The first case is a result of cholecystocolic fistula, while the second is the result of gastrojejunocolic fistula. Colonic fistulas originate from different causes: malignancy, NSAID, diverticulosis of the colon, cholecystitis, pancreatitis, lymphoma, or after radiation therapy. They can also result from a trauma, which can be post-surgical.
Introduction: Cholecystocolic fistula occurs as a result of the inflammation of the gallbladder. It arises from existing adhesions. The incidence rate is not high, but the complication is not a rarity per se. It is less frequent complication than cholecystoduodenal fistula. The main symptoms are secretory diarrhea, vitamin K malabsorption and weight loss, and thus suspicion of malignancy is usual. The treatment is surgical removal of the gallbladder, fistula and part of the colon en bloc.
Case report: A 73-year old male patient was admitted to the department after 5 months of medical treatment. Laboratory tests, coproculture, colonoscopy, abdominal ultrasonography, and gastroduodenoscopy were performed - the diagnosis was not established. The diagnosis was made by means of irrigography and short and narrow cholecystocolic fistula was confirmed. The possibility of malignant disease was not completely excluded. The patient underwent surgery after parental nutrition-adhesions, gallbladder, and the prepared fistula were removed as well as the longitudinal part of the transverse colon, which was simultaneously repaired. Ex-tempore diagnosis-the surgical specimen originated from inflammation, not from malignancy. The post-operative course was uneventful. The first post-operative stool was normal. The patient gained some weight after a few months.
Conclusion: Along with the contemporary diagnostics methods, contrast examination plays an important diagnostic role. When infection is excluded as the cause of chronic diarrhea, cholecystocolic fistula should be considered. Malignant disease should be excluded before the surgery, or it may be diagnosed during the surgery, which would determine the course of the treatment. The treatment of benign cholecystocolic fistula is surgical en bloc procedure.
