METHOD FOR DIFFERENTIAL DIAGNOSIS OF ANAL ACHALASIA IN CHILDREN

摘要

A method for the differential diagnosis of the anal achalasia in the children comprises the insertion of the filled latex balloon into the rectal ampulla with microballoon in the middle of the anal canal for recording the pressure. The minimal volume of filling the rectal balloon with the filling rate of 5 mL/min resulting in decreassin the anal pressure by at least Hg is assessed followed by the digital anal devulsion. Then the minimal volume of filling the rectal balloon is assessed once again. The difference between the pressure values obtained is calculated. When the first volume exceeds 100 mL and the difference exceeds 40 mL, the achalasia of the external sphincter is diagnosed. When the difference is less than 10 mL, the myogenic achalasia of the internal sphincter is suggested.
