Keywords: Reflux disease (RB); failure of the bauginia valve (NBZ); gastrointestinal tract (GIT); chronic duodenal obstruction (CIDP); irritable bowel syndrome (IRS); operations: bauginoplasty (BP); bauginoplasty in combination with dissection Treitz (BP + PCT); bauginoplasty in combination with duodenojejunostya (BP + DES).
