Prevention, diagnosis, and treatment of pancreatic abscess
Abstract:
Since pancreatic abscesses are a highly lethal complication of acute pancreatitis, factors influencing the genesis of major peripancreatic infection (MPI) were analyzed in 330 patients with pancreatitis. MPI developed in 28 (8.5%). Management of MPI was reviewed in 35 patients, including seven admitted with MPI. Etiology and severity of pancreatitis influenced MPI frequency. MPI was common in postoperative pancreatitis (39%), compared with alcoholic (6.6%), biliary (3.6%), or other causes (15%). "Severity" of pancreatitis was estimated by 11 early prognostic signs, which were reported previously. With fewer than three signs, MPI developed in 2.7%, three to five signs, 32%; more than five signs, 50%. Treatment of pancreatitis also influenced MPI. Early laparotomy increased MPI incidence from 1.6% to 23% in mild pancreatitis and from 24% to 67% in severe pancreatitis. Early oral feeding also appeared to predispose to MPI. Prolonged nasogastric suction and avoidance of early operation reduced MPI incidence from 16% in the first 100 patients to 5% in the next 230 patients. Outcome of MPI reflected severity of underlying pancreatitis. Mortality with fewer than three signs was 14%; with three to five signs, 65%; with more than six signs, 100%. Mortality was only 26% in 19 patients treated with radical sump drainage of the entire peripancreatic retroperitoneum, compared to 75% of 16 patients treated with conventional local drainage. In summary, MPI is related to etiology and severity of pancreatitis as quantified by early signs. Early laparotomy for pancreatitis increased MPI. Treatment of MPI with wide sump drainage appears more effective than local drainage.
Insights
Major peripancreatic infection (MPI) is a severe complication of acute pancreatitis. Its occurrence and outcomes are linked to pancreatitis causes, severity, and treatment, with wide sump drainage showing better results.
Area of Science:
- Gastroenterology
- Surgical Infections
- Critical Care Medicine
Background:
- Pancreatic abscesses are a life-threatening complication of acute pancreatitis.
- Understanding factors influencing major peripancreatic infection (MPI) is crucial for improving patient outcomes.
Purpose of the Study:
- To analyze factors influencing the development and outcomes of major peripancreatic infection (MPI) in patients with acute pancreatitis.
- To compare the effectiveness of different management strategies for MPI.
Main Methods:
- Retrospective analysis of 330 patients with pancreatitis, focusing on 28 who developed MPI.
- Evaluation of pancreatitis etiology, severity (using 11 early prognostic signs), and treatment interventions.
- Review of MPI management in 35 patients, comparing drainage techniques.
Main Results:
- MPI occurred in 8.5% of patients, with higher incidence in postoperative (39%) versus alcoholic (6.6%) or biliary (3.6%) pancreatitis.
- Pancreatitis severity, assessed by prognostic signs, strongly correlated with MPI risk (2.7% with <3 signs, 50% with >5 signs).
- Early laparotomy and oral feeding increased MPI incidence, while nasogastric suction and delayed surgery reduced it. Radical sump drainage (26% mortality) was superior to local drainage (75% mortality).
Conclusions:
- MPI development and outcomes in acute pancreatitis are significantly influenced by etiology and severity.
- Aggressive surgical management, such as early laparotomy, increases MPI risk, whereas conservative measures and effective drainage are key.
- Radical sump drainage of the peripancreatic retroperitoneum offers a more favorable prognosis for MPI compared to conventional local drainage.
