Abstract

AIM: To identify the possible predictors of early complications after the initial intervention in acute necrotizing pancreatitis.

METHODS: We collected the medical records of 334 patients with acute necrotizing pancreatitis who received initial intervention in our center. Complications associated with predictors were analyzed.

RESULTS: The postoperative mortality rate was 16% (53/334). Up to 31% of patients were successfully treated with percutaneous catheter drainage alone. The rates of intra-abdominal bleeding, colonic fistula, and progressive infection were 15% (50/334), 20% (68/334), and 26% (87/334), respectively. Multivariate analysis indicated that Marshall score upon admission, multiple organ failure, preoperative respiratory infection, and sepsis were the predictors of postoperative progressive infection (P < 0.05). Single organ failure, systemic inflammatory response syndrome upon admission, and C-reactive protein level upon admission were the risk factors of postoperative colonic fistula (P < 0.05). Moreover, preoperative Marshall score, organ failure, sepsis, and preoperative systemic inflammatory response syndrome were the risk factors of postoperative intra-abdominal bleeding (P < 0.05).

CONCLUSION: Marshall score, organ failures, preoperative respiratory infection, sepsis, preoperative systemic inflammatory response syndrome, and C-reactive protein level upon admission are associated with postoperative complications.

Keywords: Acute necrotizing pancreatitis; Intervention complications; Intra-abdominal bleeding; Colonic fistula; Progressive infection

Core tip: Intra-abdominal bleeding, colonic fistula, and progressive infection are the three major early post-procedural complications in patients with acute necrotizing pancreatitis regardless of the selected approach. Possible predictors, accurate diagnosis, and appropriate management methods are beneficial to decrease the mortality rate and convalescence, as well as promote the life quality of patients with acute pancreatitis. In this study, Marshall score, organ failures, preoperative respiratory infection, sepsis, preoperative systemic inflammatory response syndrome, and C-reactive protein level upon admission are associated with post-procedural complications. Proper and gentle intervention process, and close monitoring and evaluation of patients who are prone to suffer from postoperative complications may increase the therapeutic efficiency.
