RESUMO

BACKGROUND: Recurrence of varices is still common after endoscopic treatment of esophageal varices. In this study, predictive signs of variceal recurrence were investigated by ultrasonic (US) miniature probe in patients treated by combined endoscopic ligation and sclerotherapy. METHODS: Detectability of vessels by US miniature probe was evaluated first in rats. In 41 patients treated by combined therapy, the esophagus and the cardia region were examined by US miniature probe. In 25 patients examined by percutaneous transhepatic portography, the relationship between US miniature probe and percutaneous transhepatic portography findings was evaluated. RESULTS: The smallest vessel detected by US miniature probe was 0.3 mm in diameter in the study using intra-abdominal vessels of rat. After variceal eradication, US miniature probe showed intramural vessels in the cardia that were classified as follows: grade I, a few vessels (19 patients, 46%); grade II, uniformly scattered vessels (11, 27%); grade III, abundant vessels resembling a honeycomb (11, 27%). As the sonographic grade increased, the rate of variceal recurrence increased. As the venographic grade of staining in the distal esophagus increased, the esophageal wall became thicker and the sonographic grade at the cardia increased. CONCLUSIONS: Endosonographic evaluation of the distal esophagus and cardia is predictive of variceal recurrence.

RESUMO

BACKGROUND: Endoscopic variceal ligation is useful in the control of bleeding from esophageal varices. However, confirmation of ligation precisely at the site of bleeding is usually difficult when treating massive variceal bleeding. Characteristic endoscopic findings that appeared when ligation was performed at the site of bleeding are reported in this article. METHODS: Emergency endoscopic variceal ligation was performed in 14 patients with active bleeding from esophageal varices. Endoscopic findings after variceal ligation at the site of bleeding were compared with those at sites without bleeding. RESULTS: Active bleeding ceased just after endoscopic ligation at the site of bleeding in all patients. After ligation of the bleeding site of the varix, an unusual white-colored ball-like appearance (white ball appearance) was observed in all patients. This finding was markedly different from the purple-colored ball-like appearance that is usually observed after ligation of a varix at a site without bleeding. CONCLUSIONS: White ball appearance was a characteristic finding that appeared after ligation of a varix at the site of bleeding. This finding may be useful in the confirmation of successful ligation of a varix at its bleeding site.
