CLINICAL, IMAGING CHARACTERISTICS AND ACUTE CHOLANGITIS IN PATIENTS WITH COMMON BILE DUCT STONES AND GALLBLADDER STONES
Main Article Content
Abstract
Objective: To describe the clinical characteristics, acute cholangitis and imaging features in patients with common bile duct stones (CBDS) and gallbladder stones. Subjects and Methods: A descriptive study conducted on patients with CBDS and gallbladder stones. Results: 44 patients met the selection criteria. Common clinical symptoms included right upper quadrant and epigastric pain (90.9%), positive Murphy's sign (50%), jaundice (42.3%). The ability to detect gallstones is 93.2% on ultrasound and 97.7% on MRI; ultrasound only detects 46.5% of CBDS, whereas it is 95.5% when using MRI. The average size of CBDS on ultrasound is 7.71 ± 3.41 mm, on MRI is 5.33 ± 1.57 mm. The size of the stones retrieved by ERCP is 5.09 ± 1.61 mm. Cases with a single CBDS account for 80% on ultrasound and 76.2% on MRI. Acute cholangitis was observed in 42.3% of cases, with 36.4% being Grade I (Tokyo 2018). Conclusion: In patients with CBDS and gallbladder stones, the common clinical symptoms are right upper quadrant and epigastric pain, positive Murphy’s sign, and jaundice. The majority of cases involve only one CBDS, with an average stone size of 5.09 ± 1.61 mm. The characteristics of the stone on MRI are more consistent with those seen during ERCP than on ultrasound. The incidence of acute cholangitis is 42.3%, mostly causing Grade I.
