Patients with achalasia and reflux esophagitis have dysfunction of the esophagogastric junction. We investigated the normal function of the esophagogastric junction and functional reconstruction of the region in patients with these diseases. The results and conclusions were as follows. 1. Eleven patients with achalasiand ten patients with reflux esophagitis received functional surgical reconstruction of this region. All patients have achieved a satisfactory status after surgery. 2. The fact that surgical treatment of patients with achalasia and reflux esophagitis having hiatus hernia may be performed so effectively and safely indicates that early surgical intervention is feasible for these patients. 3. The idea of "physiological sphincter" must be broadened and take into account the crura of the diaphragm.
