Pulsed dye laser lithotripsy of bile duct stones.
Efficacy and safety of pulsed dye laser lithotripsy was tested in 25 consecutive patients in whom bile duct stones could not be extracted after endoscopic sphincterotomy. The patients had one to six (mean, 1.8) bile duct stones (diameter, 10-35 mm; mean, 18 mm) located in the common bile duct (18 cases), the intrahepatic bile ducts (6 cases), or in a long cystic duct stump (1 case). Different a...
متن کاملEndoscopic laser lithotripsy for complicated bile duct stones: is cholangioscopic guidance necessary?
BACKGROUND Endoscopic papillotomy is successful in more than 95% of the cases of choledocholithiasis. For patients with difficult bile duct stones not responding to mechanical lithotripsy, different methods for stone fragmentation have been developed. AIM To compare the results of laser lithotripsy with a stone-tissue recognizing system, when guided by fluoroscopy only or by cholangioscopy. ...
متن کاملPulsed dye laser lithotripsy for ureteric calculi.
Laser has proven to be an effective and safe method of treating ureteral stones. When the electromagnetic energy of a laser pulse is selectively absorbed by stone, a plasma fonns at the surface. This plasma, which is composed of ions and electrons, continues to absorb laser energy reaching very high pressure and generating a shock wave that fragment the stone. The degree of stone fragmentation ...
متن کاملClearance of refractory bile duct stones with extracorporeal shockwave lithotripsy
Background—Extracorporeal shockwave lithotripsy (ESWL) has been used since the mid-1980s to fragment bile duct stones which cannot be removed endoscopically. Early machines required general anaesthesia and immersion in a waterbath. Aims—To investigate the eVectiveness of the third generation Storz Modulith SL20 lithotriptor in fragmenting bile duct stones that could not be cleared by mechanical...
متن کاملLaser lithotripsy of difficult bile duct stones: results in 60 patients using a rhodamine 6G dye laser with optical stone tissue detection system.
INTRODUCTION Laser lithotripsy of bile duct stones has become a widely accepted endoscopic treatment modality for giant, impacted, or very hard stones. The procedure is usually carried out under direct endoscopic control in view of the potential risk of bile duct injuries in "blind" laser application. AIMS To investigate the use of a rhodamine 6G laser lithotriptor with an integrated optical ...
