Management of complicated acute pancreatitis: impact of computed tomography.
The usefulness of computed tomography (CT) in guiding the management of 43 patients who had a complicated clinical course of acute pancreatitis was retrospectively studied. The CT scans were performed when patients had persistent fever, leucocytosis, hyperamylasaemia, palpable abdominal masses or when there was organ failure. The CT scans showed normal findings in six patients, features of pancreatic abscess in three patients, pseudocysts in three patients and inflammatory masses (a mixture of sterile inflammation and necrosis) in 31 patients. Patients with pancreatic abscesses underwent emergency laparotomy, drainage and debridement; patients with pseudocysts had delayed drainage unless complication occurred; patients with normal CT scan or findings of inflammatory masses were managed conservatively. For patients undergoing conservative management, repeated CT scanning and percutaneous aspiration of the inflammatory mass was performed when pancreatic sepsis was strongly suspected. By this approach, basing on careful clinical and CT scan surveillance, five patients with pancreatic sepsis (pancreatic abscess and localized abscess collection in pseudocyst) underwent emergency surgery and four survived, while 25 patients with inflammatory masses were successfully managed conservatively and some who may have been operated on clinical grounds were spared unnecessary early debridement surgery.
