1. A method for closing a wound in a tubular organ using a suture thread introduced into the tubular organ, the method comprising:
inflating the tubular organ by supplying gas into the tubular organ;
resecting a lesion while the tubular organ is inflated, so that the wound is formed;
discharging gas from the tubular organ to contract an entirety of the tubular organ;
passing the suture thread through a tissue around the wound while the entirety of the tubular organ is contracted; and
gathering the tissue around the wound by pulling the suture thread passing through the tissue while the entirety of the tubular organ is contracted.
