Background: Severe acute pancreatitis (SAP) is a common critical disease of the digestive system. In addition to the clinical manifestations and biochemical changes of acute pancreatitis, SAP is also accompanied by organ failure lasting more than 48 h. SAP is characterized by focal or extensive pancreatic necrosis, hemorrhage and obvious inflammation around the pancreas. The peripancreatic fat space, fascia, mesentery and adjacent organs are often involved. The common local complications include acute peripancreatic fluid collection, acute necrotic collection, pancreatic pseudocyst, walled off necrosis and infected pancreatic necrosis. After reviewing the literature, we found that in very few cases, SAP patients have complications with anterior abdominal wall abscesses.
Case summary: We report a 66-year-old Asian male with severe acute pancreatitis who presented with intermittent abdominal pain and an increasing abdominal mass. The abscess spread from the retroperitoneum to the anterior abdominal wall and the right groin. In the described case, drainage tubes were placed in the retroperitoneal and anterior abdominal wall by percutaneous puncture. After a series of symptomatic supportive therapies, the patient was discharged from the hospital with a retroperitoneal drainage tube after the toleration of oral feeding and the improvement of nutritional status.
Conclusion: We believe that patients with SAP complicated with anterior abdominal abscess can be treated conservatively to avoid unnecessary exploration or operation.
