METHOD FOR DETERMINING THE ANGLE OF CONFLUENCE OF THE TERMINAL PORTION OF THE ILEUM INTO THE LARGE INTESTINE RELATIVE TO ITS POSTERIOR WALL DURING ENDOSCOPY Russian patent published in 2018 - IPC A61B1/05 A61B5/107 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to endoscopic examination and anatomy, and can be used to determine the angle of confluence of the terminal ileum into the large intestine relative to its posterior wall. When examining the ileocecal area during a colonoscopy, to improve the spatial orientation of the subject, they are placed on their backs. Distilled water is introduced into the lumen of the ascending colon. When analyzing endophotograms using a compass, the center of the lumen of the ascending colon is determined. There is a line connecting the front and rear bridles, from which at right angles to the center of the circle of the ascending colon. Line is then drawn along the surface of the water in the ascending colon, and from it at right angles to the center of the circle of the ascending colon. Resulting angle is taken as the angle of confluence of the ileum into the large intestine relative to its posterior wall. After that, it is measured with a protractor.

EFFECT: method allows to determine the spatial arrangement of the elements of the ileocecal region and the ascending colon, accurately determine the angle of confluence of the terminal ileum into the large intestine relative to its posterior wall during colonoscopy by placing the examinee on his back during a colonoscopy, introduction into the lumen of the ascending colon of distilled water, the technique of analysis of endophotograms.
