A study of biliary shock wave lithotripsy of gallstones sponsored by Dornier Medical Systems, Munich, began in the United States in May 1988 to evaluate the efficacy and safety of extracorporeal shock wave lithotripsy (ESWL) and the need for adjunctive therapy with ursodeoxycholic acid (UDCA). One hundred forty-one symptomatic patients with one to three …

Extracorporeal shock-wave lithotripsy (ESWL) has been applied to patients with gallstones since the mid-1980s. Lithotriptors differ by their means of shock-wave generation, the mechanisms by which they are coupled to the patient, and their imaging systems. Entry in most treatment protocols is limite …

Why some gallstones do not fragment easily to lithotripsy is unclear. The aim of the present study was to determine gallstone factors associated with resistance to fragmentation. Seventy-six cholesterol rich gallstones were subjected to physical evaluation, in vitro computed tomography, chemical analysis by infra red spectroscopy, and ultrastructural studies (of 26 matched stones) …

Removal of stones of the gallbladder and ducts is an operation during which the stones are extracted from the biliary tract. It can be performed in an open way, laparoscopically or endoscopically. During laparotomy or laparoscopy, the gallbladder or common bile duct is opened, revised, the stones are removed.

The first article regarding the role of lithotripsy in treating gallstones was published in 1988 by Heberer et al., who conducted ESWL on 250 patients. They claimed that 80% of the patients were free of stone for one year and 10% reported relapse. It was from then that the role of ESWL in treatment of gallstone was distinguished in an ...

Although alternatives to cholecystectomy are now available to treat patients with gallstones, the primary treatment of gallstone disease remains surgi…

Technical Developments and Instrumentation Gallstone Lithotripsy: In Vitro Comparison of Fragmentation with a Tunable-Dye Laser and an Ultrasonic Wire1 Michael C. Soulen, MD Kevin L. Sullivan, MD Large bile duct stones require fragmentation prior to extraction through the papilla or through a percutaneous tract.

We report the recurrence rate of gallstone within 5 years after successful lithotripsy. One hundred and fifty consecutive patients (solitary stones, 102 patients; multiple stones, 48 patients) were followed up for a median of 42 months (range 6–72) after stone clearance and cessation of bile acid therapy.

This article reviews selected aspects of the non-surgical/minimally invasive treatments of gallbladder stones (GBS) and discusses briefly the residual role of these treatments in the era of laparoscopic cholecystectomy. In patients with specific, …

Oral bile acid therapy for dissolution of gallstones, with or without extracorporeal shock wave lithotripsy, provides a useful and safe, but ultimately less effective, alternative therapy for selected patients, especially those whose medical condition and/or personal preference precludes operative cholecystectomy.

Gallbladder emptying determines early gallstone clearance after shock-wave lithotripsy

A basic understanding of shock wave generation is essential for the radiologist who performs gallstone lithotripsy. Shock waves differ from ordinary acoustic waves in that they have a rapid rise time, a positive pressure component that gives rise to compressive forces approaching 1,000 atm, and a low-amplitude sustained negative pressure (rarefactive) …

Extracorporeal Shockwave Lithotripsy (ESWL) treatment is a non-surgical treatment for the removal of Gallstones. Gallstones are nothing but crystal like particles which grow into stones in the gallbladder. These may move to the biliary tract and block the flow of the bile and cause an increase in the pressure in the gallbladder.

We evaluated 30 gallstone lithotripsy procedures performed on 27 patients with the Dornier MPL-9000 Lithotripter to determine how time was spent in the lithotripsy suite and to evaluate the various technical reasons for interrupting the administration of …

This study subjected gallstones of different sizes and composition to shock waves at different frequency and power settings using an EDAP lithotripter. Sets of …

Lithotripsy is the fragmentation of a gallstone, within the gallbladder or bile duct, by the use of sound shock waves. This procedure is similar to a kidney stone ESWL where the sound energy is applied from the exterior although an endoscopic lithotripsy is possible but …

Colonic gallstone ileus in an uncommon mechanical bowel obstruction caused by intraluminal impaction of one or more gallstones. The surgical management of gallstone ileus is complex and is potentially of high risk. There have been reports of gallstone extractions using various endoscopic modalities to relieve the obstruction. In this report we present the …

Gallstones are lumps of solid material that form in your gallbladder. They are made when the digestive juice called bile gets hard and stone-like. Gallstones can be as small as a grain of sand or as big as a golf ball.

GASTROINTESTINAL ENDOSCOPY

Gallstones are small, pebble-like stone particles of cholesterol or calcium salts that form from bile in the gallbladder. The gallbladder is located just below the liver in the upper-right abdomen and looks like a pear-shaped sac. Bile is a liquid, water-like substance made up of cells from the liver and is used for digesting food.

Gallstone Movement During Lithotripsy: Mechanisms and Effects on Fragmentation Nimish Vakil, MD, E. Carr Everbach, PhD, S. M. Gracewski, PhD We sought to examine the mechanisms of gallstone movement and its effect on gallstone fragmentation in vitro. Two experiments were performed in four specially constructed phantoms that allowed decreasing ...

In vitro lithotripsy with the Siemens Lithostar was conducted on 36 radiolucent or minimally calcified gallstones housed in an anthropomorphic phantom. The ease and pattern of fragmentation were correlated with global composition for the entire stone, regional or microcomposition (determined by Fourier-transform infrared spectroscopy), and ...

Thirty-eight patients with calcific cholecystolithiasis underwent extracorporeal shock wave lithotripsy (ESWL) of the gallbladder on an outpatient basis. Twenty-two (60%) patients had fragments smaller than 3 mm on follow-up ultrasound (US) studies after an average of 13,450 shock waves and four lit …

Brittleness of gallstones to lithotripsy: Effect of physicochemical and ultrastructural characteristics. January 1994; European Journal of Clinical Investigation 24(1):22-7

Twenty years ago, in January 1985, extracorporeal shock wave lithotripsy (ESWL) was first applied successfully in a patient with gallbladder stones. In the following years, the conditions which influence the success rate of ESWL have been extensively investigated. It was shown that the characteristi …
