Abstract:
1. A treatment method on tissues in a body cavity, the treatment method comprising: a first step of placing a fastener comprising a plurality of loops formed in a coiled shape, wherein each of the plurality of loops has the same predetermined diameter, and neighboring loops of the plurality of loops are attached to each other when the fastener is not subjected to external force, wherein the first step comprises the fastener being pushed out from an applicator inserted via a natural orifice of a patient, the fastener compressing both a first body tissue and a second body tissue to be in an ischemic condition, the first body tissue being an outer wall of a horizontal portion of a duodenum, the horizontal portion of the duodenum distal to a stomach and proximal to a downward portion of the duodenum, the second body tissue being an upper portion of a common bile duct, the upper portion of a common bile duct is a distance away from a papilla of the common bile duct; and a second step of forming a fistula, having the predetermined diameter of each of the plurality of loops of the fastener, bound by the fastener by ischemic necrosis of the compressed first body tissue and the compressed second body tissue to communicate between the horizontal portion of the duodenum and the upper portion of the common bile duct; a third step of introducing a distal portion of an endoscope inserted via a natural orifice of the patient into the duodenum, moving the distal portion of the endoscope to the vicinity of the fistula, protruding a treatment device from the distal portion of the endoscope; a fourth step of inserting the treatment device into the common bile duct through the fistula, and performing a treatment by the treatment device in the common bile duct.
