  • PROCEDURE
    Publication number: 20080161641
    Abstract: A procedure for forming an opening in a luminal organ surface while observing images from an endoscope introduced into a luminal organ through a natural orifice, and performing observation and treatment of an organ in an abdominal cavity through the opening, including the steps of: inserting an endoscope into a target luminal organ through a natural orifice of a subject; checking and identifying a region without other organs or blood vessels under observation by the endoscope; inserting a perforating treatment instrument for perforating the target luminal organ under observation by the endoscope; perforating the region where safety in an abdominal cavity outside the target luminal organ is checked in the checking step, using the perforating treatment instrument; inserting the endoscope into the abdominal cavity through the perforated portion; inserting a surgical treatment instrument for performing treatment of the organ in the abdominal cavity through the perforated portion; performing surgery under observat
