OBJECTIVETo study the effect and method of surgical treatment in patients with sliding esophageal hiatal hernia.

METHODSTo divide into two groups: fifty-two patients with sliding esophageal hiatal hernia diagnosed with gastroscopy and X-ray barium meal examination accepted operation. Forty-seven cases were treated by Nissen's operation. Three cases were treated by Hill's operation. One case was treated by Boerema's operation. One case was treated by Rampal's operation. 24-hour esophageal pH and esophageal motility were also monitored before and after operation. Thirty healthy volunteer were performed control group and were monitored by 24-hour esophageal pH and esophageal motility.

RESULTSThe patients in operation group had lower esophageal sphincter relaxation and acid reflux before operation. They became significantly ameliorative after operation. Forty-seven cases (90%) had the satisfactory effect. Two cases (4%) recrudesced.

CONCLUSIONComprehensive examination and perfect surgical choice may play an important role in the treatment of sliding esophageal hiatal hernia; The better method for sliding esophageal hiatal hernia is Nissen's operation.
