Abstract
AIM: To determine the clinical presentation, underlying etiology and short- and long-term outcomes of acute variceal bleeding (AVB).
METHODS: A retrospective descriptive cohort study of cirrhotic patients with AVB who were admitted to King Abdul Aziz University Hospital between January 2005 and December 2009. We obtained demographic data for all patients. For each patient we also obtained the clinical data at presentation; cause of liver cirrhosis, bleeding presentation (hematemesis and/or melena), presence of ascites, hepatic encephalopathy and renal impairment (RI) or hepatorenal syndrome. We carried out complete blood count, prothrombin time evaluation, and liver function tests. We also report all episodes of re-bleeding after the first episode of AVB, both during the initial admission and after discharge. We recorded the length of stay for each patient and thereby calculated the mean duration of stay for all patients. The length of follow-up after the first AVB and the outcome for each patient at the end of the study period were recorded. Causes of mortality either related to liver disease or non-liver disease cause were determined.
RESULTS: A 125 patients were enrolled in the study. The number of episodes of AVB for each patients varied between 1 and 10. Survival from the first attack of AVB to death was 20.38 mo (SD 30.86), while the length of follow-up for the living patients was 53.58 mo (SD 24.94). Total number of AVB admissions was 241. Chronic hepatitis C, the commonest underlying etiology for liver disease, was present in 46 (36.8%) patients. Only 35 (28%) patients had received a primary prophylactic beta-blocker before the first bleeding episode. The mean hemoglobin level at the time of admission was 8.59 g/dL (SD 2.53). Most patients had Child-Pugh Class C 41 (32.8%) or Class B 72 (57.6%) disease. Hematemesis was the predominant symptom and was found in 119 (95.2%) patients, followed by melena in 75 (60.0%) patients. Ascites of variable extent was documented in 93 (74.4%) patients. We identified hepatic encephalopathy in 31 (28.8%) patients and spontaneous bacterial peritonitis in 17 (13.6%). Bleeding gastric varices was the cause of AVB in 2 patients. AVB was associated with shock in 22 patients, 13 of whom (59.1%) had Child-Pugh class C disease. RI was noted in 19 (46.3%) of 41 patients in Child-Pugh class C and 14 (19.4%) of 72 patients in Child-Pugh class B. None of the patients with Child-Pugh class A disease had RI. Emergency endoscopy was effective in controlling the bleeding, although the re-bleeding rate was still high, 12 (9.6%) during the same admission and 55 (44%) after discharge. The re-bleeding rate was higher in patients with ascites, occurring in 40/55 (72.2%). The length of hospital stay was 1-54 d with a mean of 8.7 d. Three patients had emergency surgery due to failure of endoscopic treatment and balloon tamponade. The overall long term mortality was 65%. Survival from the first attack of AVB to death was 20.38 +/- 30.86 mo, while the length of follow-up for the living patients was 53.58 +/- 24.94 mo. Patients with Child-Pugh score C had a higher risk of liver disease-related mortality (67.6%). RI (developed during admission) was the main factor that was associated with mortality (P = 0.045).
CONCLUSION: The majority of patients with liver disease who present at the emergency unit for AVB are at an advanced stage of the disease. The outcome is poorer for patients who develop RI during hospitalization. (C) 2012 Baishideng. All rights reserved.
