Abstract:
Objective:To evaluate the efficacy and safety of percutaneous nephrolithotomy (PCNL) in the treatment of severe acute pancreatitis (SAP) with infected pancreatic necrosis (IPN).Methods:A retrospective analysis was conducted on the clinical data of 113 patients with SAP and IPN admitted to Qingdao Municipal Hospital between January 2018 and June 2023. The cohort included 66 males and 47 females, aged (46.2±13.6) years. Based on the treatment approach, patients were divided into two groups: those who underwent percutaneous catheter drainage (PCD) alone were assigned to the PCD group ( n=60), and those who received PCNL were assigned to the PCNL group ( n=53). Clinical parameters such as age, sex, number of debridement procedures, and postoperative complications were recorded. Results:Compared with the PCD group, the PCNL group had a higher CT severity index [8(6, 9) vs. 7(6, 8)], a greater proportion of patients with multiloculated abscesses [71.7%(38/53) vs. 41.7%(25/60)], and a higher percentage of patients with IPN involving >50% necrosis [56.6%(30/53) vs. 33.3%(20/60)]. These differences were statistically significant (all P<0.05). The PCNL group also showed a higher proportion of patients with post-treatment IPN necrosis involving <30% [91.4%(49/53) vs. 70.8%(42/60)], a lower rate of requiring step-up laparoscopic or open surgery [3.8%(2/53) vs. 10.0%(6/60)], fewer debridement sessions [2(1, 4) vs. 4(2, 6)], and a shorter total hospital stay [45(35, 58) d vs. 54(23, 72) d]. These differences were statistically significant (all P<0.05). Additionally, the PCNL group had lower rates of postoperative complications, including enteric fistula [3.8%(2/53) vs. 11.7%(7/60)], intra-abdominal bleeding [5.7%(3/53) vs. 13.3%(8/60)], and pancreatic fistula [15.1%(8/53) vs. 20.0% (12/60)]. These differences were also statistically significant (all P<0.05). The recurrence rate of abscesses was significantly lower in the PCNL group [11.3%(6/53) vs. 16.7%(10/60), χ2=4.14, P=0.042]. Conclusion:PCNL is an effective treatment for SAP complicated by IPN. Compared with PCD, it improves the clearance of necrotic tissue, reduces the number of debridement procedures, shortens the total hospital stay, and lowers the risk of postoperative complications.
