A simple endoscopic intubation technique in esophageal obstruction.

Endoscopic intubation was effected in 42 cases of malignant esophageal stenosis during the period 1979-1981. The stenosis was dilated with the aid of thermoplastic probes passed through a rigid esophagoscope of sufficient length, whereupon a tube was introduced under endoscopic control and left in situ in the malignant stricture. This "rigid" technique is suitable for process confined to the esophagus. Introduction of the tube requires adequate endoscopic skill and is not devoid of risk. Perforation, the gravest risk, occurred in two cases. Proximal tube migration was observed in five patients.
