Observation on the esophageal varices and their collaterals with ultrasonic microprobe before and after EVL / 中华消化内镜杂志

ABSTRACT

Objective In order to evaluate the efficacy of esophageal varices ligation( EVL) , ultrasonic microprobe (UMP) was used to observe the esophageal varices and their collaterals before and after EVL. Methods Sixty patients merely with esophageal varices underwent ultrosonography via UMP before and 4,8,12 weeks after EVL and were divided into three groups:( Ⅰ )esophageal varices(EV) ( Ⅱ )esophageal and paraesophageal vein(PEV) varices( Ⅲ ) esophageal, para esophageal and perforating vein( PV) varices. Results In the following-up, the effective rate of type Ⅰ , Ⅱ , Ⅲ were 75% , 25% , 0% ; The recurrence rate 16% , 75% , and 100% respectively. PEV occurred in 12 out of 24 cases of group Ⅰ and broadened in all of the cases of group Ⅱ and Ⅲ; PV occurred in 11 out of 20 cases of group Ⅱ and all cases in groups M , and broadened in all cases of group Ⅲ. Conclusion Endoscopic ultrasonography can be served as guidance in selecting therapeutic measure in treating EV. EVL is merely suitable in treating EV; in EV patients with PEV and/or PV measures other than EVL should he selected.
