[Endoscopic therapy of giant choledochal calculosis].

The paper reports the results of conventional endoscopic treatment in 100 consecutive cases of giant lithiasis of the common bile duct. A giant calculus is one whose dimensions exceed 2 cm. Endoscopic therapy proved successful in 73% of cases, with an 8% incidence of complications. The success of endoscopic treatment is related to the anatomical conditions of the biliary tract and the diameter of calculi. Mechanical lithotripsy has proved efficacious in all cases where it was used, whereas poor results were obtained using MTBE infusion through a naso-biliary tube. ESWL provided encouraging results. Cases which were not resolved using endoscopic methods were treated using intervention radiology or surgery, or both.
