RESUMO
BACKGROUND: Acute pancreatitis (AP) is a common gastrointestinal disorder with a high mortality rate. This study evaluated the incidence of and risk factors for reoperation after debridement of AP. METHODS: This retrospective study included 168 patients diagnosed with AP who had undergone debridement between January 2007 and December 2017 at our hospital. Patients were divided into single-operation and reoperation groups separately. RESULTS: Sixty-eight (40.24%) patients underwent reoperation after AP debridement. The main procedure for reoperation was debridement of necrosis. In univariate analysis, the risk factors for reoperation included younger age; higher admission temperature and heart rate; higher levels of C-reactive protein (CRP), blood urea nitrogen and creatinine; higher Acute Physiology and Chronic Health Evaluation II score and rate of continuous renal replacement therapy; shorter operation interval; lower postoperative albumin level; and high incidence of preoperative and postoperative complications. Multivariate logistic analysis indicated that independent risk factors for reoperation included higher levels of C-reactive protein and creatinine in admission, preoperative percutaneous catheter drainage, and postoperative complications. CONCLUSIONS: The general characteristics and clinical procedures of patients with AP after debridement might affect prognosis and reoperation. The identification of risk factors could help clinicians to provide specific treatment, better ward management, and stratification of reoperation risk.
