QUANTITATIVE ASSESSMENT OF ANTI-REFLUX PROCEDURE AND ESTIMATION OF OPERATIVE RESULT WITH THE USE OF INTRAOPERATIVE MANOMETRY

Intraoperative manometry in reference to the pre- and postoperative values of LESP was attempted in a total of 27 cases with achalasia of the esophagus, sliding type of esophageal hiatal hernia, esophageal varices and in those underwent proximal gastrectomy with valvuloplastic anastomosis. All except the proximal gastrectomy cases were subjected to eigher fundic patch or to its modified procedures.
Results are summarized as follows: 1) Achalasia cases showed sufficient reduction in LESP at the end of operation and little changes in postoperative LESP. 2) Cases subjected to proximal gastrectomy maintained the steady level of LESP throughout all the chances of measurement. 3) Cases with hiatal hernia and esophageal varices showed 37 to 50% reduction from end-operative to postoperative LESP. 4) With the improvement and standardization of the method of manometry i it is estimated that the intraoperative manometry may become a useful tool for the intraoperative assessment or correction of anti-reflux procedures and accurate estimation of the operative result.
