Abstract:
1. A method for suturing a perforation of a stomach, comprising the steps of: inserting an observation device into the stomach and drawing a proposed incision line; determining a position to be sutured before incising the stomach; incising the stomach along the proposed incision line to form the perforation and performing a medical treatment in an abdominal cavity through the perforation; suturing the perforation by tightening up a suture thread that penetrates through the stomach via the position to be sutured after performing the medical treatment; wherein the step of determining the position to be sutured comprises the step of: determining puncture positions which are mutually symmetrical with reference to the proposed incision line by drawing on the stomach a mark on each of the puncture positions and drawing a line connecting the mark on each of the puncture positions, wherein the line is approximately orthogonal to the proposed incision line; puncturing the puncture positions with a needle of a suture instrument to make the needle penetrate through a wall of the stomach; pushing out anchor from a tip of the needle into an outside of the stomach, the anchor being fixed to the suture thread; and drawing out the needle from the wall to make only the suture thread penetrate through the wall and to place the anchors at the outside of the stomach.
