Serous fluid (light color) that accumulates in the peritoneal cavity (abdomen).
If the amount of accumulated fluid is large, it can cause discomfort in the patient. It is possible that the doctor will decide to perform a small puncture on the abdomen to drain this fluid. This is a simple procedure that will be performed in the patient's room. It does not require fasting and is painless (a local anesthetic is usually used). Special care is not required after this puncture and it the patient will note great relief.
It is common for ascitic fluid to accumulate again, particularly if of tumor origin. Therefore, it is possible that you will require several punctures during the course of your disease.
