RESUMO
BACKGROUND: A choledochal cyst is a cystic dilatation of the biliary tree, also termed a biliary cyst, including an intrahepatic cyst as well. Magnetic resonance cholangiopancreatography (MRCP) is the gold standard investigation of choice for this pathology. Todani classification is most commonly used to classify choledochal cysts. MATERIALS AND METHODS: A total of 30 adult patients with choledochal cysts presenting at our center from December 1, 2009, to October 31, 2019, were studied retrospectively. RESULTS: The mean age was 35.13 years ranging from 18 to 62 years with a male-to-female ratio of 1:3.29. Of the patients, 86.6% presented with abdominal pain. Total serum bilirubin was raised in six patients with a mean of 1.84 mg/dL. MRCP was done in all patients, which had almost 100% sensitivity. Two cases had anomalous pancreaticobiliary duct union. In our study, we found only type I and type IVA cysts according to the Todani classification (type IA = 56.3%, IB = 11%, 1C = 16%, and IVA = 17%). The mean size of the cyst was 2.37 cm. Complete cyst excision with Roux-en-Y hepaticojejunostomy was performed in all patients. Four patients had surgical site infections and two had bile leaks. One patient developed hepatic artery thrombosis. All complications were eventually managed conservatively. Mortality was nil in our study with the mean postoperative stay being 7.97 days. CONCLUSION: Adult presentation of biliary cysts is not an uncommon entity in the Indian population and should be considered as a differential diagnosis of biliary pathology in adult patients. Complete excision of cysts with bilioenteric anastomosis is the current treatment of choice.
RESUMO
INTRODUCTION: Gastrointestinal tuberculosis is common in the developing world especially in the lower socioeconomic groups. In elderly, it may mimic malignancy. CASE PRESENTATION: A 46-year-old female presented with a 6 month history of diffuse pain in abdomen with low grade fever and loss of weight and appetite. Clinically, differential of malignancy of the large bowel was considered. The computerized tomography(CT) scan of the abdomen revealed a diffuse concentric long segmental thickening of terminal ileum, ileo ceacal junction, ascending colon and narrowing of the transverse colonic end of the splenic flexure suggesting an infective etiology. Colonoscopy showed an ulcero-nodular lesion at the splenic flexure raising the possibility of colonic cancer and thickening of ascending colon and caecum. Colonoscopic biopsy from both sites, on histopathology, showed a moderate mixed inflammation and occasional lymphoid collection and crypt abscesses in the lamina propria giving a differential of tuberculosis or Crohn's disease. Biopsy smear showed occasional acid fast bacilli(AFBs) and the gene Xpert detected mycobacterium tuberculosis(MTB). The patient was started on anti Koch's therapy(AKT). DISCUSSION: In this case the differential diagnosis was malignancy of the colon, inflammatory bowel disease and tuberculosis as all these conditions may have similar clinical profile and radiological findings. Tuberculosis of bowel was considered as the most probable diagnosis due to the CT findings. But the colonoscopy suggested malignant etiology. CONCLUSION: Possibility of tuberculosis should be kept in mind while dealing with synchronous lesions in large intestine.
