The anomalous connection of the pancreaticobiliary duct (ACPBD) without accompanying dilatation of the bile duct (non‐dilated type of ACPBD) has recently been found to be associated with gallbladder cancer at a rather high rate. We analyzed the diagnostic process of 5 patients with non‐dilated type of ACPBD including 3 asymptomatic cases and reviewed the literature. Symptoms and laboratory data were not useful in detecting this type of lesion. All our patients were checked by ultrasonography for gallbladder lesions which are suggested by: wall thickening, multiple polyps, intramural gall stones, cholecystolithiaisis, and debris. ACT revealed only wall thickening of the gallbladder. An EUS revealed a high rate of ACPBD in addition to the ultrasonographic findings of gallbladder lesions obtained by US. An ERCP was effective in clearly demonstrating ACPBD, but was not so useful for the diagnosis of concomitant gallbladder lesions. Therefore, an US is considered to be a useful means for screening this disease, and EUS is useful as a procedure to follow in order to select patients with or without ACPBD, because EUS can be conducted on an outpatient basis and is highly sensitive in detecting ductal anomalies in ACPBD. Therefore, the US/EUS serial examination is thought to be an effective means for diagnosing this disease.
