My surgeon said thought that i had developed a seroma after lap. ventral hernia but after having open hernia to fix a defect he said that what he thought was a seroma was more like a cyst is normal?

Decription of seroma: Maybe he is describing the seroma as being cyst like. Seroma developments are common complications of surgery. Perhaps, it was drained and it resolved, but ask your doctor if it's drained completely and whether or not it will recur.

Abnormal: Ideally one heals without fluid collection = seroma or thick wall ='which is like a cystic collection ask a bit more.

Need more info: A cyst filled with fluid is essentially the same as a seroma just with a capsule around it. Was it infected? Did he/she find blood (hematoma)? Did he/she leave a drain? Did he/she leave the wound packed open? If so, this can be a nl post op issue. Or is your surgeon saying this is a different cyst unrelated to the surgery ie, a sebacceous cyst? If so it was probably there before the surgery.

Maybe: There are a lot of factors involved that makes this a complex problem. If fluid collection within the wound is essentially the same thing as a seroma. If you don't feel like you're getting the right answers, consider seeking a second opinion from a surgeon who specializes in hernia surgery. You may be able to find a surgeon at the americas hernia society website.

Still a seroma: Seromas tend to be free, undefined fluid collections. However, if they become chronic they can be associated with a rind or capsule of varying thickness. This is still a seroma. Low grade infection within the seroma would also tend to produce a rind or capsule around it.
