3.Results The DGR and GER existed in 5.62% cases. Conclusions Causes of diseases of DGR and GER after cholecystectomy are lose of storage function of bile.
4.In HH patients the number of reflux episodes (NRE) lasting for 5 min or longer, the duration of the longest episode (DLE), the percentage of time of pH<4 for total periods and mean duration of reflux episodes were higher at lying than at standing position ( P <0 05).
5.Among them, HVR involved m0st in puLmonary artery valve (33 cases, 64.8% ), secondly in tricuspid valve (12 cases, 35. 3 % ), thirdly in mitralvalve (6 cases, 11. 7% ).
6.In order to estimate eccentric MR,two parameters named turbulent intensity and regurgitate angle were proposed to modify the effective regurgitate orifice area(EROA) based on traditional PISA algorithm.
9.Valve regurgitation was assessed according to American Society of Echocardiography recommendations.
10.Objective To study the relationship between recurrent respiratory infection(RRI)and gastroesophageal reflux(GER)in children.
