Diaphragmatic hernia in a cat

First perform a midline abdominal exploratory on the cat. In this cat, you can immediately see the large peritoneal pericardial diaphragmatic hernia. The gall bladder has herniated through the opening, as well as some of the liver lobes.

The gall bladder can be grasped using atraumatic thumb forceps to pull the liver back into the abdominal cavity. 

Once all the hernia contents have been removed, you still have to break down some of the hepatic ligaments in order to be able to fully see inside the pericardial sac.

You’ll be able to clearly see the heart beating within the pericardial sac, along with some pericardial effusion. When you suction out some of the liquid, you must be very careful not to break down the pleura that separates the pericardial sac from the pleural space because if you do, then you must put in a chest tube.

Then close the hernia using a simple continuous suture pattern with 3-0 Prolene. You want to use something non-absorbable so that it’s going to be there for a while.

Following hernia repair, it’s really important to do a complete abdominal exploratory to check for strangulation of any organs that were present in the area.
