• Thoracotomy for a vascular ring anomaly in a puppy

We passed an endoscope down Charlie’s oesophagus and confirmed megaoesophagus “upstream” of the level of the heart. The scope wouldn’t pass further.

A left-sided intercostal thoracotomy (surgical approach into the chest between the ribs) was made and dissection revealed that the aorta was on the right side of the chest, not the left where it should have been. A blood vessel that should have closed down at the time of birth was still patent and was pinching the oesophagus. This was ligated and cut to release the pressure on the oesophagus. A tube could now easily be passed down the oesophagus into the stomach. There was serious blood loss during this part of the procedure and a transfusion was required.

Charlie required close supervision in the hospital with us in Burton-Upon-Trent for a few days post-operatively and he was fed via a gastrostomy feeding tube (a tube that passes directly into his stomach through the left body wall just behind the last left rib). He made excellent progress in the early postoperative period. Once he was stable, he was discharged for his owners to continue with the tube feeding, and for continued antibiotic and analgesic drug administration via the tube.

We weren’t sure to what degree, if any, his oesophagus would recover. Often the stretched part of the oesophagus never recovers properly and remains flabby, stretched, and unable to close around food particles and propel them downwards towards the stomach. We warned the owners that he was not yet “out of the woods”. Charlie would likely need long-term management for megaoesophagus which requires feeding small meals regularly from a height to use gravity to assist the passage of food down the oesophagus.

Tiny amounts of food were offered by mouth a couple of weeks post-operatively, with the pup restrained in a “head-up” position. Sadly there were respiratory complications a few days later and Charlie succumbed to these. It was a very sad outcome for what had been a very satisfyingly successful case up to that point.
