After surgery for peritonitis, if the inflammation cannot be completely controlled, the patient is often placed a drainage tube so that the inflammatory fluid in the peritoneum continues to drain out. Accordingly, the care of abdominal drainage after surgery for peritonitis is an important component of postoperative care, helping patients quickly heal and leave the hospital.

Percutaneous abdominal drainage is an adjunctive treatment for acute pancreatitis, helping to effectively drain fluid pockets containing inflammatory and cytotoxic substances, while reducing the volume of abdominal fluid. Abdominal drainage reduces the number of cases of acute pancreatitis requiring surgical intervention.
