説明
in our patient was potentially preventable, and the general recommendation of endoscope insertion under vision seems appropriate. In the majority of cases, inverted endoscopes can either be pushed forward into the stomach and then straightened or simply pulled back into the oropharynx,6 possibly made more rigid by prior insertion of a biopsy forceps. If for technical or anatomical reasons the endoscope remains impacted in the esophagus, major surgery or possibly destruction of the instrument may be the consequence. The use of an auxiliary endoscope to liberate an impacted instrument was reported,I2 recently. In both cases the inverted endoscope was advanced forward into the stomach. This was not possible in our patient due to a narrow stricture of the esophagus. Thus we had to use the auxiliary endoscope in a different manner. We connected it to the impacted instrument with a flexible wire through the biopsy channel under direct vision. This allowed careful straightening in the esophagus without damage to the mucosa. We observed no serious complications and major surgery was avoided by the technique described. Although we used general anesthesia, this might not be needed.
