腹腔镜夹脱落后血管安全性的实验研究

Experimental Study of Independent Vessel Security after Ligation with Laparoscopic Clips

目的 探讨腹腔镜夹在术后早期脱落后其管腔残端的安全性情况 .方法 利用钛夹和可吸收夹将 4 0只兔的左侧颈动脉和右侧颈外静脉夹闭并剪断 ,1、2、4、7、14天后再移去钛夹和可吸收夹 ,测量管腔残端能否抵制管腔内高压 .结果 钛夹与可吸收夹在术后早期闭合管腔的能力大小为 :钛夹 >可吸收夹 .结论 腹腔镜手术应正确封合管腔 ,避免并发症的发生 。

Objective To determine what time laparoscopic clips in the closed vessel are released and moved when the vessels can achieve safety. Methods The right jugular vein and the contralateral carotid artery in each of 40 rabbits were ligated with either titanium clips or absorbable clips and then divided. After 1?2?4?7?or 14 days following ligation, the laparoscopic clips were removed, and the vessel's resistance to leakage was quantitated. Results The capacity of titanium clips and absorbable clips in sealing vessel: titanium clips > absorbable clips. Conclusions In laparoscopic operation, we should choose correct methods in sealing vessel. Thus perfect effects can be achieved and complications can be avoided.
