Hello I am Dr. Joey. Thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 16 years of experience. I look forward to working with you.
So smart to look for more information! So, I may need to ask a few further questions to know what has been done and where you are with diagnosing him.
First, let me say fluid in the abdomen is never a good sign. However, we can usually get information based on analysis of that fluid to tell us if this is septic fluid (such as from puncture of an abdominal organ or rupture of pancreatic abscess) versus clear fluid that suggests leakage (as might be seen with organ failure- liver or pancreas) or blood. I cannot clearly determine an indication for surgery based on what you have written; so I need to ask some question and find out if this is actually clearly indicated.
So, my questions:
1) Was a fluid tap and then analysis performed (this would be sent to the lab for a pathologist to review)? Results?
2) Was an abdominal ultrasound performed by someone very good at reading these - this can evaluate the pancreas and all other organs to look for the potential source; primarily we want to see the pancreas to see if there is an abscess and confirm inflammation, and to screen for cancer as this would be a leading cause of the fluid he is experiencing?
3) WAs his lab work normal, particularly his protein levels? With pancreatitis, they could potentially get low and then this would cause fluid to leach into the abdomen and would be a CONTRAINDICATION to surgery (don't do it because he won't be able to heal and could die)?
4) What is his blood pressure? Hypertension can lead to fluid accumulation; and a search for the cause of hypertension is really needed (e.g., liver failure vs heart failure).
Thanks for giving me a bigger picture of what is going on. It helps me to provide you with the best information possible and gauge where you are in the process of determine the problem.
