A case of oesophageal obstruction following the removal of a tracheoesophageal valve by division is presented. The obstruction was caused by impaction of a portion of the valve at a previously undiscovered benign oesophageal stricture. The obstruction was resolved by interventional radiology with no long-term sequelae. To the best of our knowledge this complication has not been described previously.
In a 1-year register, retained urinary catheters were encountered on 23 occasions. In vitro tests showed that 2 ml of ether or chloroform injected through the inflation channel of catheter balloons caused disruption within a few seconds but liquid paraffin took over 20 min, leaving an unacceptable amount of debris. A new method of removal using diagnostic ultrasound to identify the balloon of the retained catheter is described, together with suggestions for removal of retained catheters occurring under different circumstances.
