One-step laparoscopic pancreatic necrosectomy verse surgical step-up approach for infected pancreatic necrosis: a case-control study.

BACKGROUND: The surgical step-up approach often requires multiple debridements and might not be suitable for infected pancreatic necrosis (IPN) patients with various abscesses or no safe route for percutaneous catheter drainage (PCD). This case-control study aimed to investigate the safety and effectiveness of one-step laparoscopic pancreatic necrosectomy (LPN) in treating IPN.
METHODS: This case-control study included IPN patients undergoing one-step LPN or surgical step-up in our center from January 2015 to December 2020. The short-term and long-term complications after surgery, length of hospital stay, and postoperative ICU stays in both groups were analyzed. Univariate and multivariate logistic regression analyses were performed to explore the risk factors of major complications or death.
RESULTS: A total of 53 IPN patients underwent one-step LPN and 37 IPN patients underwent surgical step-up approach in this study. There was no significant difference in the incidence of death, major complications, new-onset diabetes, or new-onset pancreatic exocrine insufficiency between the two groups. However, the length of hospital stay in the one-step LPN group was significantly shorter than that in the surgical step-up group. Univariate regression analysis showed that the surgical approach (one-step/step-up) was not the risk factor for major complications or death. Multivariate logistic regression analysis indicated that computed tomography (CT) severity index, American Society of Anesthesiologists (ASA) class IV, and white blood cell (WBC) were the significant risk factors for major complications or death.
CONCLUSION: One-step LPN is as safe and effective as the surgical step-up approach for treating IPN patients, and reduces total hospital stay. Copyright: © World Journal of Emergency Medicine.
