The feeling in your stomach when.........

Meet Leroy. 

Leroy is a 297 pound, 35-year-old, male Cuban Crocodile. Cuban Crocodiles are one of the most endangered crocodiles in the world. Their native habitat is a very small area, less than 200 square miles, of the Zapata Swamp in Cuba. Leroy lives at Zoo Miami and has been there since 1998.

In October of last year, Leroy ate a large metal can of lubricating oil that was being used in the maintenance of his enclosure. The can had been accidentally knocked over during the maintenance and fell into the water near Leroy. Crocodiles have a natural feeding response to splashes in the water and, unfortunately, the disturbance the can caused in the water attracted Leroy. At first, Leroy just played with the can. Eventually, he bit into the can and then swallowed it whole.

Given the size of the can, the caregivers and veterinary staff of the zoo were concerned, as it was unlikely to pass. Leroy had a foreign body. Being a can, Leroy’s foreign body was metal and could be seen on radiographs. Therefore, to help identify the location of the can, radiographs (x-rays) were taken. Let’s take a look at the reconstructed image. In these images, Leroy would have been laying down on his stomach with his head at the top and his tail at the bottom of the image.

As you can see, the can was very big and it wouldn’t have been able to make it through the intestinal system. Because the can was in the stomach, an attempt at removing it with a scope was made. Unfortunately, this was unsuccessful and it was decided that surgery would be performed to remove the can. 

Leroy was prepared for surgery similarly to the way a dog or cat would. He was moved into the operating room at the zoo and his skin was cleaned. However, one big difference was the way the abdomen was opened. In a dog or cat, the approach to opening the abdomen to get to the stomach would be through what is called a midline incision. This means a cut down the center of the abdomen. In the crocodile, the approach is through an incision in the left flank. This is a cut in the left side of the abdomen from the back to the front of the body. The reason the approach is different is that in dogs and cats the abdomen is one compartment and in crocodiles, there is some additional compartmentalization. This approach from the side makes it easier to get to the stomach. Also, crocodiles will sometimes pull their bodies along the ground and an incision on the underside of the abdomen would get very dirty.

The surgical opening and closing of the stomach (in a dog/cat or a crocodile) is called a gastrotomy and this was performed in Leroy similarly to how it would be performed in a dog. Take a look at this picture of the can being removed from Leroy’s stomach.   *These images may be considered graphic.

The stomach of the crocodile is larger than that of a dog and it took some feeling around in the stomach to find the can. Take a look at the can after it was removed. There is another can next to the one Leroy ate for comparison. Those are some big holes made by Leroy’s teeth! Can you go back to the radiographs and see the holes in the can on the radiograph? 

Closing the gastrotomy site is performed with suture in a couple of layers. The closure of the stomach is similar in the dog, cat, and, crocodile. However, Leroy’s skin is of course much tougher than a dog or cat. Crocodile skin has what looks like scales on it. Those square areas that look like scales are called scutes. Scutes are very thick and make suturing the skin a little more complicated. A thicker suture was used in Leroy’s skin than would be used in a dog or cat.  Scutes can also be seen on turtle shells and on the feet of birds. You can see some of the scutes on Leroy in his picture and on his radiograph. Can look back to Figure 1 and find them? Find out how you did! 

The great news is that Leroy did very well after surgery and recovered with no complications!!! There were a lot of people happy to see Leroy make it through his surgery and continue to do well. It takes a large team working together to achieve a successful surgery on such a large, non-domesticated animal including zookeepers, caregivers, zoo administration, veterinary technicians, and veterinarians. 

It is amazing to see what people working together can achieve. I feel fortunate to have been a part of this fantastic team.
