  • Abstract
  • Look Inside

 Peroral cholangioscopy (POCS) was performed in 11 cases with biliary tract carcinoma. There were nine cases of bile duct carcinoma and two cases of gallbladder carcinoma. No dilatation of the intrahepatic duct was seen in any of the cases. Baby scopes (CHF-B20, XCHF-B34, or XPF-14 long, OLYMPUS) and mother scopes (TJF-M20, TJF-20, or JF-1T30) were employed for these purposes.

 Successful observation of the carcinoma was attained in nine cases (81%). Diagnosis was made by biopsy and cytology. Endoscopic findings showed that three cases of bile duct carcinoma were yellowish and another four cases were the same color as normal mucosa. Invasion from gallbladder carcinoma was pale in two cases. Three cases of bile duct carcinoma had elevated lesions and rough-surfaced mucosa. In two bile duct carcinomas and two gallbladder carcinomas there was stricture of the common bile duct, and dilated vascular pattern.

 In conclusion, if abnormal findings of ERC are recognized, we recommend POCS using a guide-catheter. Moreover, if there is a suspicion of carcinoma, we recommend performing endoscopic sphincterotomy and taking a biopsy specimen under endoscopic control.
