Apparatus and method for endoscopic anastomosis of the stomach and the bowel

An apparatus for endoscopic anastomosis of the stomach and the bowel of a patient to allow food to bypass the duodenum, comprising:

• a tube insertable into the stomach, the tube having a proximal end and a distal end;
• surgical apparatus which is deployable at the distal end of the tube and is at least partially insertable through the tube;
• and
• at least one operating element connected or connectable to the surgical apparatus for operating the surgical apparatus from the proximal end;
• wherein the surgical apparatus is configured for establishing anastomosis between a first area of the stomach and a second area of the bowel.

A method of performing endoscopic anastomosis of the stomach and the bowel of a patient to allow food to bypass the duodenum, the method, characterized in the following steps:

• insertion of an apparatus into the stomach and attaching to the stomach wall in the first area;
• piercing and/or cutting through the stomach wall and deploying an insertable element outside of the stomach;
• advancing a counter element on the inside of the stomach to the first area;
• clamping the stomach wall of the first area between the insertable element and the counter element and cutting a hole into a section of the first area with the cutting device;
• advancing the apparatus through the hole and locating the target location making up the second area for the anastomosis;
• attaching to the outside of the bowel wall in the second area;
• piercing and/or cutting through the bowel wall and deploying the insertable element inside the bowel;
• pulling the insertable element to bring the first area into close contact with the second area;
• advancing the counter element with a fixation device and clamping the first and second area between the counter element and the insertable element;
• cutting a hole into a section of the second area with the cutting device and stapling and/or suturing the edges of the first area and second area together with the fixation device.
