What is the impact of capsule endoscopy in the long term period?

AIM: To assess the clinical impact of capsule endoscopy(CE) in the long-term follow-up period in patients with obscure gastrointestinal bleeding(OGIB). METHODS: One hundred and forty-one patients who applied CE for OGIB between 2009 and 2012 were retrospectively analyzed, and this cohort was then questioned prospectively. Demographic data of the patients were determined via the presence of comorbid diseases, use of non-steroidal anti-inflammatory drugs anticoagulant-antiaggregant agents, previous diagnostic tests for bleeding episodes, CE findings, laboratory tests and outcomes.RESULTS: CE was performed on 141 patients becauseof OGIB. The capsule was retained in the upper gastrointestinal(GI) system in two of the patients, thus video monitoring was not achieved. There were 139 patients [62% male, median age: 72 years(range: 13-93 years) and a median follow-up duration: 32 mo(range: 6-82 mo)]. The overall diagnostic yield of CE was 84.9%. Rebleeding was determined in 40.3%(56/139) of the patients. The rebleeding rates of patients with positive and negative capsule results at the end of the follow-up were 46.6%(55/118) and 4.8%(1/21), respectively. In the multivariate analysis, usage of NSAIDs, anticoagulant-antiaggregant therapies(OR = 5.8; 95%CI: 1.86-18.27) and vascular ectasia(OR = 6.02; 95%CI: 2.568-14.146) in CE were detected as independent predictors of rebleeding. In the univariate analysis, advanced age, comorbidity, and overt bleeding were detected as predictors of rebleeding.CONCLUSION: CE is a reliable method in the diagnosis of obscure GI bleeding. Negative CE correlated with a significantly lower rebleeding risk in the long-term follow-up period.

Current state and clinical outcome in Turkish patients with hepatocellular carcinoma

AIM To investigate clinical, etiological, and prognostic features in patients with hepatocellular carcinoma.METHODS Patients with hepatocellular carcinoma who were followed-up from 2001 to 2011 were included in the study. The diagnosis was established by histopathological and/or radiological criteria. We retrospectively reviewed clinical and laboratory data, etiology of primary liver disease, imaging characteristics and treatments. ChildPugh and Barcelona Clinic Liver Cancer stage was determined at initial diagnosis. Kaplan-Meier survival analysis was done to find out treatment effect on survival. Risk factors for vascular invasion and overall survival were investigated by multivariate Cox regression analyses. RESULTS Five hundred and forty-five patients with hepatocellular carcinoma were included in the study. Viral hepatitis was prevalent and 68 patients either had normal liver or were non-cirrhotic. Overall median survival was 16(13-19) mo. Presence of extrahepatic metastasis was associated with larger tumor size(OR = 3.19, 95%CI: 1.14-10.6). Independent predictor variables of vascular invasion were AFP(OR = 2.95, 95%CI: 1.38-6.31), total tumor diameter(OR = 3.14, 95%CI: 1.01-9.77), and hepatitis B infection( OR = 5.37, 95 % CI : 1.23-23.39). Liver functional reserve, tumor size/extension, AFP level and primary treatment modality were independent predictors of overall survival. Transarterial chemoembolization(HR = 0.38, 95%CI: 0.28-0.51) and radioembolization(HR = 0.36, 95%CI: 0.18-0.74) provided a comparable survival benefit in the real life setting. Surgical treatments as resection and transplantation were found to be associated with the best survival compared with loco-regional treatments(log-rank, P < 0.001).CONCLUSION Baseline liver function, oncologic features including AFP level and primary treatment modality determines overall survival in patients with hepatocellular carcinoma.
