Patients in the observative group recovered without any complications while one patient in the control group who complicated with bile leakage was cured through laparoscopic exploration,ligation of the remnant cystic duct,and abdominal drainage 20h after the operation.

术后观察组未出现近远期并发症，对照组出现1例胆漏，术后20h腹腔镜下探查，行胆囊管残端结扎，腹腔引流治愈。

Irrigation and drainage through presacral double-cavity tube and operation were used in patients respectively.

对吻合口漏的患者采用手术及保守治疗（骶前双腔管冲洗引流加肛管引流）。

During the peroid of applying the tube, the urocystic stimulus syndrome and indisposition on renal region appeared in 21 cases, three cases were urinary system infection, there was no urinary fistula, obstruction of ureter and stoma stenostomia in all patients.

置管期间，出现膀胱刺激征及肾区不适21例，泌尿系感染3例。无尿漏及输尿管梗阻及吻合口狭窄发生。

The inside sealing structure of valve are plane sealing with blade shape, which can realize large ventilate areas with little unseal height. The outside sealing structures of valve are corrugated tube sealing without leakage point.

阀门的内密封结构采用形如刀口的平面密封，具有平面密封的特点(小的开启高度能获得较大的通气面积)，同时密封轴向力适中；外密封采用与外界无漏点的波纹管密封。

The experimental results show the validness of the mechanism analyses.2. According to the generation mechanism of the leak acoustic signal, the characteristics of the leak acoustic signal are investigated. The auto correlation technology is adopted to descript the leak signal characteristics due to the ability to analyze the coherence of time series. A new procedure to identify the leak acoustic signal from the disturbed noises is proposed based on the conjunction of correlation and approximate entropy algorithm.3. The principle and application in leak location of the correlation and the adaptive filter techniques are introduced. The problems of the traditional leak location methods are analyzed.4. In order to establish the leak detection signal model, the leak acoustic propagation characteristics are investigated experimentally.

从泄漏声产生机理出发，分析了管道泄漏处湍流拟序结构与空泡间相互作用的机理，认为在该机理作用下，泄漏声信号产生过程具有&不可重复&的特征；由于相关函数具有分析时间序列拟序结构的能力，且近似熵从统计的角度区别时间过程的复杂性，因此，提出将信号相关分析和近似熵理论相结合的方法，提取泄漏声信号&不可重复&的特征，辨识管道泄漏故障发生；在实际检测现场，由于各种管内和管外固定声源噪声(如阀门噪声、工地施工噪声等)常导致泄漏误判和漏点定位错误，重点分析了管内固定噪声源的产生机理和特征，为复杂干扰环境下的泄漏辨识提供理论支持。
