Clinical application of modified Anyang type 2 esophageal intubation instrument--a new esophageal intubation method.

The preliminary experience in the clinical use of Anyang Type 2 esophageal intubation instrument, designed by ourselves, in 11 patients with severe esophageal obstruction due to advanced carcinoma of the esophageal was reported. The diagnosis of all 11 cases was confirmed by barium-meal roentgenography. After intubation, all the patients could take liquid or soft diet by mouth. There was no operative mortality and the patients survived 2 to 14 months (mean 5.7 months). All of them could take food by mouth before death. The clinical application proved that the intubation has been a safe and suitable management.
