General and Diagnostic AspectsThe controversial issue of the cost-effectiveness of screening all cirrhotic patients for esophageal varices was raised in a number of abstracts. In one study using the Markov model, universal endoscopic screening was found not to be cost-effective when compared to empirical medical prophylaxis for variceal bleeding [1]. The cost-effectiveness of screening endoscopy could, however, be improved if a subgroup of cirrhotic patients could be identified that would not need screening for large varices. In this context, absence of splenomegaly and a platelet count > 100 000 were found to be associated with a low risk of developing varices, particularly large varices [2]. This was confirmed in another study in which predictors of the presence of esophageal varices in patients with a recent histological diagnosis of cirrhosis were investigated in 250 patients. Among various clinical, biochemical, and ultrasound variables, a longitudinal spleen diameter of > 112 mm was found to be an independent predictor of the presence of esophageal varices [3].
Endoscopic TechniquesThe importance of identifying the exact site of variceal rupture at endoscopy and subsequent targeted endoscopic treatment was underlined in one study, as it was found to be associated with a significantly lower rebleeding rate [4]. In a study aiming to detect risk factors associated with rebleeding 1 -5 days after variceal ligation, it was found that active bleeding at the index endoscopy was associated with early rebleeding [5]. The shortterm and medium-term mortality rates from bleeding varices treated using endoscopic band ligation were found to be better than those reported in the literature, in a retrospective analysis of data obtained from a North American center [6]. In order to facilitate injection sclerotherapy, a Japanese group designed a transparent hood to be mounted on the tipp of the endoscope, provided with three U-shaped slits to fix the targeted varix during injection [7]. Mini-loop ligation of esophageal varices was tried in another study and was compared to sclerotherapy. It was found to be effective, relatively easy to use, and more tolerable for patients. However, the variceal recurrence rate after 1 year was higher in the mini-loop group [8]. Guiding sclerotherapy with endoscopic ultrasonography to ensure periesophageal vein obliteration was found to be a safe and effective method of treating esophageal varices [9]. However, the authors did not state clearly the advantages achieved by this technique over conventional sclerotherapy.The use of argon plasma coagulation for the eradication of esophageal varices was a topic of one study again this year, in which it was used 7 days after one session of sclerotherapy with 5 % ethanolamine oleate. The entire mucosa of the distal 4 -5 cm of the esophagus was circumferentially coagulated in one session. This was found to be an effective and relatively safe procedure, which was associated with fewer complications in comparison with subjecting the patient to a second s...
