A method is provided to collect liquid, such as pancreatic juice water, and saline, from a body cavity of a subject. In the method, a tool is inserted through the body cavity to reach a target site in the body cavity. A body position of the subject is adjusted such that the wall surface of the body cavity including the target site intersects with a direction of gravitational force and the liquid present in the body cavity gathers on the wall surface intersecting with the direction of gravitational force. A recess is formed to be concaved on the wall surface in the direction of the gravitational force by making the tool press the wall surface of the body cavity. Therefore, the liquid present or discharged in the body cavity is accumulated in the recess. The liquid accumulated in the recess is taken out of the body of the subject.

A lesion identification system for surgical operations has a light marker adapted for placement in the vicinity of a lesion inside an organ of an organism, and a location-identifying device detecting a light emitted from the light marker at an outside of the organ for identifying a location of the lesion. The marker includes a light emitter and an engagement member associated with the emitter to be engageable with a wall of the organ. The engagement member includes a clip. The light emitter emits light with a wavelength in a near-infrared range. The device includes an endoscope comprising an inserter section having an image pickup element picking up a reflected light, involving the light from the light marker, at an outside of the organ, and an image pickup unit allowing the reflected light, picked by the image pickup element, to be generated as an image for display on a monitor.

A medical instrument performs at least one of suture and ligation to form a suitable knot in a piece of suture within a body cavity. This medical instrument includes a suture having a first end portion, a second end portion, and at least one loop formed in advance at an intermediate portion between the first and second end portions to have a predetermined size, and a suture suitable for application to a body tissue, and a cylindrical body for holding the loop to almost maintain the size thereof. The body has a fastening portion for fastening at least one portion of the suture. The medical instrument further includes an inserting instrument which is to be inserted into the body cavity, which has a distal end portion that can be arranged in the body cavity, and an operating portion, arranged outside the body, for operating the distal end portion thereof, and on which a holding member having the suture wound thereon is mounted. The distal end portion of the inserting instrument projects beyond the loop held by the holding member, and has a gripping member capable of gripping the suture. This inserting instrument causes the first end portion of the suture gripped near an insertion port to the body cavity and in the body cavity to pass through the loop, thereby forming a knot.
