Treatment of difficult bile duct stones using mechanical, electrohydraulic and extracorporeal shock wave lithotripsy.

Over a 34-month period (1989-1991), 791 patients were diagnosed at endoscopic retrograde cholangiography to have bile duct stones. All patients underwent sphincterotomy and attempted extraction by Dormia basket. This was successful in 683 patients (86%). The remaining 108 patients with "difficult stones" (mean age 72 years) underwent mechanical, electrohydraulic or extracorporeal shock wave lithotripsy according to the following algorithm: (1) Mechanical lithotripsy for stones which could not be extracted after entrapment in the Dormia basket (n = 33); (2) peroral cholangioscopic electrohydraulic lithotripsy for stones which could not be engaged in the Dormia basket (n = 65); or (3) extracorporeal shock wave lithotripsy for intrahepatic stones (n = 10). Stone fragmentation and clearance was successful in all patients treated by mechanical lithotripsy, was unsuccessful in one patient submitted to electrohydraulic lithotripsy due to inability to insert the cholangioscope into the bile duct and failed in 3 patients treated by extracorporeal shock wave lithotripsy. Overall, 95% of difficult bile duct stones refractory to conventional endoscopic basket extraction were removed using the above lithotripsy techniques. There were no serious procedure-related complications.

[Diffuse pseudo-diverticulosis of the esophagus with severe cranial stricture, axial hiatal hernia and Barrett syndrome].

We report about a patient with esophageal intramural pseudodiverticulosis (EIP) who was referred to our department for further investigation of dysphagia. EIP is a rare, pathologically well defined disease, most frequently characterized by stricture-associated symptoms. The diagnosis of EIP is made by barium swallow and can be confirmed by endoscopy which shows typical diverticula-like changes of the esophageal wall.

Endoscopic treatment of Mirizzi's syndrome.

Electrohydraulic lithotripsy has been shown to be an effective non-surgical treatment for common bile duct and intrahepatic duct stones. This technique was applied via the endoscopic retrograde route in 14 patients (mean age, 70) with the Mirizzi syndrome, all of whom were at high risk for surgery. The procedure was performed under strict cholangioscopic guidance. Twelve patients had a single stone and two had multiple stones impacted in the cystic duct. Stone diameter was 1.5 cm in one patient, 2 to 3 cm in nine patients, and greater than 3 cm in four patients. Insertion of the babyscope and stone fragmentation were successful in all patients. Complete stone clearance required one session in 12 patients and two sessions in two patients (both with multiple stones). In one patient post-procedural leakage of contrast medium from the cystic duct into the peritoneal cavity was noted. This was attributed to pressure necrosis induced by the impacted stone. The patient had an uneventful course of recovery, and leakage resolved with conservative management. Mortality was zero. Endoscopic treatment of the Mirizzi syndrome with electrohydraulic lithotripsy seems to be an effective and relatively safe alternative to surgery.
