【摘要】 目的：为解决胆道癌引起的恶性梗阻和胆道术后良性狭窄提供新的治疗手段。方法：自１９９３年５月至１９９６年１０月，对１２例不能根治切除的胆道恶性肿瘤和１例良性胆道梗阻患者施行记忆合金胆道内支架内引流术。经胆总管探查直视下放置支架１１例，在Ｔ管和ＰＴＣＤ窦道途径放置支架各１例。结果：手术均获成功，无并发症。１１例术后平均７天黄疸逐渐消退。结论：镍钛形状记忆合金胆道内支架在治疗胆道狭窄具有充分扩张和支撑狭窄段胆道的优良特性，能恢复和维持正常胆道生理，有效防止胆道再阻塞，有良好的性价比。便于基层医院推广使用。更多还原

【Abstract】 In an attempt to treat binary tract stricture caused by cancerous bile duct, the equipment Ni-Ti memory-alloy form was ed to expansile and support the bile duct. Since May 1993 to October 1996,Ni-Ti memory-alloy froms were used in 13 pa- tients. Results: 11 patients received the equipment during operation. The operation was simple, all operations met with suc- cess and had no complication.The jaundice in 11 cases gradually disappeared within 7 days. The short-term curative effect rate was 80%. All the cases were followed after operation. The long-term curative effect rate was 90%. The usefulness of operations with Ni-Ti form memory-alloy . stands was discussed in detail.更多还原
