Gastroesophageal reflux and treatments

We studied 118 patients using endoscopic color Doppler ultrasonography (ECDUS) to evaluate perforating veins of esophageal varices. The ECDUS was performed with a PENTAX FG‐32UA or FG‐36UX (7.5 MHz, convex type) and a HITACHI EUB 565 was used as a display device. We defined the perforating veins as communicating vessels between esophageal varices and paraesophageal veins. We evaluated the detection rate and the direction of blood flow in the perforating veins. Color flow images of perforating veins were obtained in 43 of the 118 (36.4%) patients. We classified the perforating veins into three types. Type 1 was characterized as an inflow type from paraesophageal veins to esophageal varices, Type 2 as an outflow type from esophageal varices to paraesophageal veins and Type 3 as a mixed type showing both inflow and outflow. Type 1 was recognized iri 37 (86.0%), Type 2 in four (9.3%) and Type 3 in two (4.7%) of 43 patients. We conclude that ECDUS is a useful modality for obtaining diagnostic color flow images of perforating veins, and for evaluating the blood flow direction in perforating veins.
