体外震波碎石疗法(ESWL)是一种非侵入性方法,过去仅限于用于直径<15mm的透X光胆囊结石,体内外实验已证实钙化的胆石也能被ESWL所粉碎,后者能否被胆汁酸溶解或自胆囊内排出,文内临床研究结果给予了肯定的回答,使ESWL仅适合于20%胆石病例的指征扩大到较大的结石以及部分钙化的胆固醇结石。临床研究对象选自患有胆绞痛史,单颗结石,直径21±5mm,平片上见边缘不透X线(厚达3mm)的透X线结石,这些结石仍以胆固醇为主,仅外壳为钙化
Extracorporeal shock wave lithotripsy (ESWL) is a noninvasive method that used to be limited to X-ray clear gallbladder stones <15 mm in diameter. In vitro and in vivo experiments have demonstrated that calcified gallstones can also be crushed by ESWL Was dissolved in bile acid or excreted in the gallbladder. Affirmative answers were given to the clinical results of the in silico study so that ESWL was only suitable for the indication of 20% of gallstone cases to expand to larger stones and partially calcified cholesterol stones. The subjects were selected from patients with history of bile colic, single calculus, diameter 21 ± 5mm, plain radiographs of see-through radiographs (thickness up to 3mm), which were still cholesterol-dominated, For calcification
