Abstract

Background. Ultrasonography (US) does not come up to the expectations in the diagnosis of the causes of common bile duct (CBD) dilation.
Objectives. An assessment of the usefulness of endoscopic ultrasonography (EUS) in the diagnosis of the causes of CBD dilation.
Material and Methods. The authors examined 30 persons (16 females and 14 males) with CBD dilated > 7 mm in US. In these patients the authors performed EUS with the usage of Pentax FG−38UX echoendoscope of 5–10 MHz frequency connected with EUB 6000 Hitachi ultrasonograph looking for the cause of CBD dilation. Findings gathered were verified with the usage of endoscopic retrograde cholangiopancreatography (ERCP) or magnetic resonance cholangiopancreatography (MRCP).
Results. In 16 patients the authors found stones in CBD. In ERCP or MRCP the frequency of CBD stones was a bit higher. In these examinations CBD stones were found in 18 patients. The authors found out that pancreatic head carcinoma was the cause of CBD dilation in 8 patients; in 2 patients the authors diagnosed ampullary carcinoma and in 1 patient – carcinoma of distal part of CBD. In 1 patient the authors pointed out a benign stricture of CBD with dilation above the stricture.
Conclusion. EUS is a useful diagnosing method of the causes of CBD dilation.

Streszczenie

Wprowadzenie. Ultrasonografia (USG) nie spełnia oczekiwań w diagnostyce przyczyn poszerzenia przewodu żół− ciowego wspólnego (p.ż.w.).
Cel pracy. Ocena przydatności ultrasonografii endoskopowej (EUS) w rozpoznawaniu przyczyn poszerzenia p.ż.w.
Materiał i metody. Zbadano 30 osób (16 kobiet i 14 mężczyzn), u których badanie USG jamy brzusznej wykazało poszerzenie p.ż.w. > 7 mm. U tych chorych wykonano EUS za pomocą echoendoskopu Pentax FG−38UX sprzężonego z ultrasonografem EUB 6000 firmy Hitachi, poszukując przyczyny poszerzenia p.ż.w. Uzyskane rozpoznania weryfikowano za pomocą wstecznej endoskopowej cholangiografii (ERCP) lub cholangiografi i rezonansu magnetycznego (MRCP).
Wyniki. U 16 chorych stwierdzono kamicę p.ż.w. za pomocą EUS. W ERCP lub MRCP częstość kamicy p.ż.w. była nieco większa. W tych badaniach kamicę p.ż.w. stwierdzono u 18 osób. Raka głowy trzustki jako przyczynę poszerzenia p.ż.w. wykazano u 7 chorych, u 2 chorych rozpoznano raka brodawki Vatera i u 1 – raka końcowego odcinka p.ż.w. U 1 osoby stwierdziliśmy łagodne, bliznowate zwężenie p.ż.w. z poszerzeniem jego światła powyżej zwężenia.
Wnioski. EUS jest przydatną metodą w diagnostyce przyczyn poszerzenia p.ż.w..
