胰管结石的外科分型及处理对策

目的 探讨胰管结石的外科分型并根据外科分型制定相应的有效处理对策。方法结合文献对33例胰管结石的诊断及处理进行回顾性分析。总结不同类型胰管结石治疗方法与结果,提出胰管结石的外科分型和处理对策。结果根据影像学(B超、ERCP、CT)检查结果和手术探查结果,将胰管结石分为四型：(1)I型：结石主要位于胰头部,主要处理方法是采用内镜取石,介入治疗失败或疗效不佳可行胰头十二指肠切除(Whipple手术);(2)Ⅱ型：结石主要位于胰体部,主要处理方法是采用胰管切开取石胰管空肠吻合(Puestow 手术);(3)Ⅲ型：结石主要位于胰尾部,主要处理方法是采用胰尾部加脾切除;(4)Ⅳ型：结石广泛分布于头、体和尾部主胰管,主要处理方法是采用Puestow．Gillesby和胰颈部离断,胰管探查取石加胰管两断端空肠Rous-en-Y吻合手术。结论正确的术前及术中诊断、分型,结合针对性的个体化处理对策在慢性胰腺炎导致的胰管结石治疗中具有重要意义。

The classification and management of pancreatic duct stone

OBJECTIVE: To set up a stand for surgical classification of pancreatic duct stone and evaluate the benefits of different management according to the classification. METHODS: Retrospectively analysis the diagnosis and prognosis of different management of 33 cases pancreatic duct stones to establish a new standard of classification and strategy of management of pancreatic duct stone. RESULTS: According to the results of imaging examination (B-US, CT, ERCP) and finding during surgery, pancreatic duct stone can be classified into four different types: Type I: The stones mainly located in the head of pancreas. Endoscopic pancreas drainage and remove of stones is the first line choice of treatment. If it fail the Whipple procedure should be applied. Type II, The stones mainly located in the body of pancreas. It can be treated by Pusetow procedure. Type III, The stones mainly located in the tail of pancreas. The resection of the tail of pancreas or combined with spleenectomy was recommended for the management of this type stones. Type IV, The stones can be found from the head to tail of the main duct of pancreas. The Pusetow-Gillesby procedure or dividing of the neck of pancreas removing stones from both ends of pancreatic duct and reconstructed by two ends pancreatic duct-ileostomy in Roux-en-Y fashion are the choice of management. CONCLUSION: The invadulaized strategy of the management based upon correct diagnosis and classification play the most important role in the treatment of pancreatic duct stone.
