COLONOSCOPY TECHNIQUE Russian patent published in 2014 - IPC A61B1/31 

FIELD: medicine.

SUBSTANCE: endoscope is inserted into the colon; air is pumped to stretch the colonic lumen, and the endoscope is advanced to the head of the blind colon; air is aspirated. The endoscope is pendularly moved and advanced along the folds. Air is pumped to stretch the colonic lumen completely; the endoscope is advanced to the 'jacket' mark of 40 cm; air is aspirated at the same time until the colonic lumen comes down. Air is pumped to stretch the colonic lumen completely; the endoscope is advanced to a mark of 60 cm; air is aspirated at the same time until the colonic lumen comes down. Air is pumped to stretch the colonic lumen completely; the endoscope is pulled to a mark of 45 cm; air is aspirated at the same time until the colonic lumen comes down. Air is pumped to stretch the colonic lumen completely; the endoscope is advanced to a mark of 70 cm; air is aspirated at the same time until the colonic lumen comes down. Air is pumped again to stretch the colonic lumen completely; the endoscope is pulled to a mark of 50 cm; air is aspirated at the same time until the colonic lumen comes down. Then, air is pumped again to stretch the colonic lumen completely; the endoscope is advanced to a mark of 80 cm; air is aspirated at the same time until the colonic lumen comes down; air is pumped, and the head of the blind colon is identified. If identification appears to be impossible, the last examination cycle is repeated with the endoscope positioned at the mark of 80 cm; air is aspirated from the colonic lumen until the colonic lumen comes down, and the endoscope is pulled to the mark of 50 cm. Then, air is pumped again to stretch the colonic lumen completely; the endoscope is advanced again to the mark of 80 cm; air is aspirated at the same time until the colonic lumen comes down; air is pumped, and the head of the blind colon is identified.

EFFECT: performing painless effective colonoscopy with the total colon examination with reduced time of examination, including it in patients with a pronounced pain reaction and abdominal adhesions.
