BACKGROUND: The aim of the study was to evaluate endoscopic ultrasonography (EUS) as a single method for diagnosing cholecystolithiasis in patients with a clinical suspicion of cholecystolithiasis, but with a normal transabdominal ultrasonography (TUS). METHODS: A prospective study was performed on patients with biliary type of colic and normal US of the gallbladder. All patients had at least one normal TUS examination (mean 2.1, range 1-5) performed by an experienced radiologist. All patients were subsequently examined with EUS. EUS examination was performed with either a mechanical radial scanning echo-endoscope (Olympus GF-UM20) or a linear echo-endoscope (Pentax FG32-UA or FG34-UA). Patients in whom EUS demonstrated cholecystolithiasis were offered laparoscopic cholecystectomy within 2 weeks. RESULTS: A total of 35 patients (31 F and 4 M) were included. In 18 out of 35 (52.4%) patients cholecystolithiasis was diagnosed by EUS. In 15 out of 17 patients the EUS diagnosis was verified by surgery. At follow-up after 12 months, 13 of the 15 patients (87%) with verified gallbladder stones had no abdominal discomfort, whereas 2 patients (13%) complained of persistent and unchanged abdominal pain. CONCLUSION: EUS seems to be a promising imaging method in the detection of microlithiasis in the gallbladder in patients with clear biliary colic and normal transabdominal US.
