Perforation suturing method

Abstract

A perforation suturing method has the steps of: inserting a needle into a wall of a hollow organ at a periphery of the perforation formed in the hollow organ, and piercing the wall; withdrawing the needle from the wall after delivery of an anchor attaching suture thread from the needle, and having the suture thread transit the wall; and tightening the suture thread so that the mated insertion points at the time of insertion of the needle into the wall approximately coincide after having the needle pierce the wall at the periphery of the perforation a plurality of times, and making surfaces of the wall where the insertion points are formed coincide with each other.

1 . A perforation suturing method comprising, the steps of: 
 inserting a needle into a wall of a hollow organ at a periphery of the perforation formed in the hollow organ, and piercing the wall;    withdrawing the needle from the wall after delivery of an anchor attaching suture thread from the needle, and having the suture thread transit the wall; and    tightening the suture thread so that the mated insertion points at the time of insertion of the needle into the wall approximately coincide after having the needle pierce the wall at the periphery of the perforation a plurality of times, and making surfaces of the wall where the insertion points are formed coincide with each other.    
   
   
       2 . The perforation suturing method according to  claim 1 , wherein the needle is inserted into the hollow organ via a tool that is inserted from a natural orifice in a living body.  
   
   
       3 . The perforation suturing method according to  claim 1 , wherein the hollow organ is a digestive organ, and the needle is inserted from the mucous membrane side of the digestive organ.  
   
   
       4 . The perforation suturing method according to  claim 1 , wherein the insertion point is formed in a muscular layer exposed on an inner circumferential surface of the perforation, and the needle pierces the muscular layer diagonally relative to the inner circumferential surface of the perforation.  
   
   
       5 . The perforation suturing method according to  claim 1 , further comprising a step of resecting a mucous membrane of the inner surface of the hollow organ, wherein the step in which the suture thread is made to transit the wall includes a step of inserting the needle into a surface on an interior side of a muscular layer exposed by resection of the mucous membrane.
