Choledochoscopy in the laparoscopic treatment of patients with choledocholithiasis: a single-centre study ; Холедохоскопія в лапароскопічному лікуванні хворих із холедохолітіазом: досвід одного центру

Choledochoscopy is aminimally invasive procedure used for laparoscopic bile duct exploration and the removal of bile duct stones. However, there is insufficient information available about its advantages in diagnosing choledocholithiasis and its role in laparoscopic choledocholithoextraction. Objective — to compare the diagnostic efficacy of imaging techniques and choledochoscopy in patients with choledocholithiasis and to evaluate the role of choledochoscopy in laparoscopic choledocholithoextraction. Materials and methods. The study examined the results of 128 patients with calculous cholecystitis and choledocholithiasis who had laparoscopic choledocholithoextraction in combination with choledochoscopy. We assessed the sensitivity and specificity of ultrasound, CT, and MRI in the diagnosis of choledocholithiasis, as well as the efficacy of one‑stage treatment of calculous cholecystitis and choledocholithiasis using choledochoscopy and laparoscopic choledocholithoextraction. Results. Imaging techniques demonstrated limited sensitivity and specificity in determining the diameter and number of common bile duct stones. Atotal of 89(69.5%) patients achieved complete bile duct clearance after blind laparoscopic choledocholithoextraction: 86(81.1%) had choledochotomy, and 3(13.6%) underwent transcystic common bile duct exploration. The combination of choledochoscopy and laparoscopic choledocholithoextraction ensured the complete removal of bile duct stones in 97.6% of patients. Conclusions. The imaging techniques used for determining the number of common bile duct stones in choledocholithiasis had sensitivity and specificity rates of 41.4% and 92.7% for ultrasound, 72.7% and 83.3% for CT, and 86.7% and 60.9% for MRI, respectively. Atotal of 89(69.5%) patients achieved complete bile duct clearance after blind laparoscopic choledocholithoextraction: 86(81.1%) had choledochotomy, and 3(13.6%)underwent transcystic common bile duct exploration. Choledochoscopy was required for laparoscopic choledocholithoextraction in ...
