RESUMO
OBJECTIVE: To determine the efficacy of Argon Plasma Coagulation (APC) in terms of improvement in hemoglobin level and disappearance of telangiectasia as endoscopic treatment for Gastric Antral Vascular Ectasia (GAVE) and Diffuse Antral Vascular Ectasia (DAVE) syndrome in liver cirrhosis. STUDY DESIGN: Quasi experimental study. PLACE AND DURATION OF STUDY: Department of Gastroenterology and Hepatology of Shaikh Zayed Hospital/ Federal Postgraduate Medical Institute, Lahore, from January, 2006 to July, 2007. METHODOLOGY: Cirrhotic patient with gastric vascular ectasia were enrolled and followed-up for 18 months with repeated sessions of APC. Efficacy of APC was evaluated on the basis of patient's symptoms, transfusion requirements and hemoglobin levels. APC was performed by using ERBE generator set at 60 W and flow rate 2.0 L/min using primarily endfiring probes. RESULTS: Fifty patients were enrolled in the study. Mean age was 55.78+1.24 years with 32 males and 18 females giving a male to female ratio 1.7:1. Forty two patients were in Child's Class C and 8 in Child's Class B. Presenting complaints were malena and anemia. Two hundred and fifty three APC sessions were carried out; mean 5.06+1.5 sessions per patient. Mean follow-up period after the last session was 8.5+3.7 months. Mean increase in the hemoglobin level was 1.35+0.24 g/dl. There was no death of any patient during the study period. CONCLUSION: Treatment with APC is an effective and safe method to decrease blood loss in patients with GAVE and DAVE.

OBJECTIVE: To determine the frequency of Hepatopulmonary Syndrome (HPS) in patients with cirrhosis of the liver. STUDY DESIGN: Observational cross-sectional study. PLACE AND DURATION OF STUDY: Department of Gastroenterology and Hepatology, Shaikh Zayed Hospital, Lahore, from April 2005 to March 2006. PATIENTS AND METHODS: Fifty consecutive patients admitted with liver cirrhosis were recruited. Twelve patients were excluded due to inadequate echocardiography image quality and inability to perform lung function tests. The diagnosis of cirrhosis was made on clinical, biochemical, serological and metabolic workup, ultrasound abdomen or liver biopsy. Complete blood count, liver function tests, prothrombin time, serum albumin, electrocardiography, chest radiograph, transthoracic contrast echocardiography, arterial blood gas analysis and pulmonary function tests (FEV1) were performed. Results were analyzed as percentages. Chi-square test of proportions and t-test were applied. RESULTS: Total patients evaluated were 38. Mean age was 47.92 +/- 11.38 years, with male (68.4%) to female (31.6%) ratio of 2.1:1. The commonest cause of cirrhosis was hepatitis C (71.1%). Out of the 38 patients, 11 (28.9%) had HPS including 5 (13.2%) with overt HPS and 6 (15.8%) with subclinical HPS. All patients with HPS had hepatitis C with Child-Pugh-Turcotte (CPT) class C. Factors associated with HPS were digital clubbing, arterial hypoxemia and intrapulmonary vascular dilatations (p=0.02, 0.05 and 0.000 respectively). CONCLUSION: In this study, 28.9% patients with cirrhosis of the liver had HPS. All belonged to child class C due to hepatitis C. Digital Clubbing, arterial hypoxemia and intrapulmonary vascular dilatations were important features of hepatopulmonary syndrome.
