A 54-year-old man with early stage chronic pancreatitis and an impacted ductal stone in the pancreatic head complicated by a 2 cm abscess was treated with pulsed dye laser lithotripsy using an automatic stone tissue differentiation system under fluoroscopic control. This system automatically switches off the laser on contact with tissue. The 0.25 mm quartz fiber introduced into the pancreatic duct via a 5 French teflon catheter delivered 165 out of 1000 pulses at contact with the stone (100 mJ, 10 Hz). Partial stone disintegration was achieved making mechanical stone removal possible which initially failed. No major side-effect occurred. This new laser with a stone detection system seems to render fluoroscopically guided laser lithotripsy in the pancreatic duct safer thus warranting further clinical trials.
一名54岁男性，患有早期慢性胰腺炎，胰头有一枚嵌顿性导管结石，并伴有一个2厘米的脓肿，在荧光镜控制下使用自动结石组织分化系统进行脉冲染料激光碎石术治疗。该系统在与组织接触时会自动关闭激光。通过一根5法式聚四氟乙烯导管将0.25毫米的石英纤维插入胰管，在与结石接触时发出了1000次脉冲中的165次（100毫焦，10赫兹）。实现了结石部分破碎，使得最初失败的机械取石成为可能。未发生重大副作用。这种带有结石检测系统的新型激光似乎使胰管内荧光镜引导下的激光碎石术更安全，因此值得进一步进行临床试验。
