The sonographic criteria for positive IHPS are Pyloric muscle thickness (MT) &gt; 3 mm, pyloric Canal length (CL) &gt;14 mm. Postoperative MT &amp; CL at 2 month, 4 month &amp; 6 month were determined and results were analysed with the preoperative pyloric parameters. Statistical analysis used: Mean and standard deviation of values were obtained by using Microsoft excel and statistical significance was analysed by regression study of grouped variables showing p \u2013 value by Microsoft excel.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Pyloric parameters (MT &amp; CL ) gradually attain normal values over months and 80 % of patients showed resolution of pyloric MT &amp; CL values by 6 months.
