Abstract:
1. A method for suturing a perforation, comprising the steps of: inserting a first observation device which is provided on a distal end of an endoscope having at least two channels including a first channel and a second channel from a natural opening of a living body into a hollow organ; inserting a second observation device which is inserted in the first channel and is retained therein into the hollow organ accompanying the insertion of the endoscope; inserting a tip of the second observation device through the perforation into a body cavity by making the tip of the second observation device protrude from the distal end of the endoscope through the first channel; observing a puncture position from an inside of the hollow organ by the first observation device and from a body cavity side of the hollow organ by bending the inserted tip of the second observation device to face the puncture position; inserting a needle of a suture unit from the natural opening into the hollow organ by inserting the needle through the second channel provided in the endoscope; thrusting the needle into a tissue around the perforation to make a suture thread puncture the tissue via the needle; drawing the second observation device back to the inside of the hollow organ; and closing the perforation by tightening up the suture thread puncturing the tissue, wherein the puncture position is a position through which the needle passes.
