ENDOSCOPIC TREATMENT FOR ACUTE BILIARY PANCREATITIS
1999
Worldwide, gallstones are the most common cause of acute pancreatitis, a disorder that ranges in severity from mild to life-threatening. How gallstones cause pancreatitis is hotly debated, as is the need for endoscopic decompression of the bile duct in sick patients. This article is a critical analysis of the existing data.
Analysis of radiolucent gallstones by computed tomography for in vivo estimation of stone components.
1990
. Successful oral litholytic and other non-operative therapies of gallstones require exact determination of the stone components. Since computed tomography (CT) provides highly sensitive measurement of density, we performed a study to evaluate whether CT measurement of stone density allows a prediction of the composition of radiolucent gallstones. Twenty-eight patients presenting with 29 radiolucent gallbladder (n= 17) or common bile duct stones (n=12) were included. Prior to operative or endo-scopic therapy the attenuation values (Hounsfield Units, HU) were assessed in vivo by CT under standardized conditions (Somatom II, 125 KV, 130 mAs). After surgical or endoscopic stone removal the con…
Extrakorporale Stoßwellenlithotripsie von Gallenblasensteinen: Wie viele Patienten sind geeignet?
2008
The proportion of patients with gallbladder stones suitable for extracorporeal shockwave lithotripsy (ESWL) was analysed prospectively in 200 patients aged 17-76 years (62 males, 138 females) with symptomatic cholecystolithiasis. Criteria for inclusion were clinical symptoms, solitary stones (diameter 10-30 mm) or up to three stones with comparable total volume, contractile gallbladder, no calcification of stones, normal biliary tract anatomy. To check these criteria a step-by-step diagnostic procedure was instituted which consisted of history, ultrasonography with contractility test, abdominal X-ray film, computed tomography measurement of stone density, and endoscopic retrograde cholangio…
Lithotripsy of gallbladder stones in 1992: Improved indications and actual results
1992
ESWL of gallbladder stones and subsequent adjuvant oral dissolution is a safe and comfortable therapy of symptomatic cholecystolithiasis. This method is limited on highly selected 10 to 15% of patients. Recent experience indicates that the ideal indication is given in patients with radiolucent solitary gallstones (diameter ≤2 cm) which are harboured in a gallbladder with unimpaired contractility. 1 year after ESWL 80% of those patients present with a stone free gallbladder. Computed tomography of gallstones may probably improve selection of patients and therapeutic success.
Fragmentation of bile duct stones: a prospective systematic in vitro evaluation of argon plasma coagulation, cryotechnology, and water-jet technology
2009
Background and study aim Choledocholithiasis is a common disease in the West. Lithotripsy by mechanical methods using baskets and by laser or electrohydraulic methods varies in effectiveness. With argon plasma coagulation (APC), high temperatures are used for devitalization and fragmentation; cryogenic techniques use the selective controlled application of freeze-thaw cycles to devitalize pathological tissue; and the dissecting water jet exploits the high pressure action of a thin laminar jet. We aimed to assess the feasibility and effectiveness of APC, cryotechnology, and the dissecting water jet as options for the fragmentation of bile duct stones. Methods In an in vitro feasibility study…
