ABSTRACT
Objective:To analyse the clinical efficacy and outcome of early abdominal paracentesis drainage (APD) in the treatment of severe acute pancreatitis (SAP).Methods:The clinical data of 107 SAP patients with massive abdominal fluid in Shanghai General People Hospital from May 2017 to December 2021 were collected and analyzed. Patients were divided into APD group ( n=56) and NO-APD group ( n=51) according to whether they underwent APD or not within 3 days after admission. The APD group was then divided into abdominal compartment syndrome (ACS) subgroup ( n=29) and NO-ACS subgroup ( n=27) according to whether ACS had occurred or not at the time of puncture. Patients' general data, the duration of systemic inflammatory response (SIRS), length of ICU stay, the trends of intra-abdominal pressure and inflammatory indicators (white blood cell count and the content of C-reactive protein) within 1-3 days after admission, incidence of infection complication, step-up therapy, discharge or death were recorded. Results:The intra-abdominal pressure were 18.6±5.6mmHg , 13.7±4.2mmHg (1 mmHg=0.133 kpa) in APD group and NO-APD group, respectively. The intra-abdominal pressure of APD group was significantly higher than that of NO-APD group, and the difference was statistically significant ( P=0.000). Compared with NO-APD group, the duration of SIRS was significantly shortened in APD group [3(2, 4) days vs 4(3, 6) days, P=0.029]. On day 1, 2 and 3 after admission, the intra-abdominal pressure was 18.6±5.6 mmHg, 16.4±4.7 mmHg and 13.5±3.9 mmHg in APD group, and was 13.7±4.2 mmHg, 12.3±3.6 mmHg and 11.0±2.6 mmHg in NO-APD group, respectively. The intra-abdominal pressure of the APD group dropped faster than the NO-APD group ( P=0.004). The white blood cell count was (14.8±4.8), (10.5±4.5) and (9.0±3.8)×10 9/L in APD group, and was (14.2±5.4), (12.3±7.3), (11.7±5.3)×10 9/L in NO-APD group, respectively. Compared with the NO-APD group, the decrease rate of white blood cell count was faster in APD group ( P=0.006). The C-reactive protein content was (153.6±47.1), (150.4±10.5) and (108.8±49.4)mg/L in APD group, and were (174.8±31.1), (191.6±29.4) and (186.8±45.5)mg/L in NO-APD group . The content of C-reactive protein in APD group decreased significantly, while that in NO-APD group did not decrease. There was a significant difference between the two groups ( P=0.009). In the subgroup comparisons, the duration of SIRS in the ACS subgroup was significant longer than that in the NO-ACS subgroup [4(3, 5) days vs 2(1, 3)days, P=0.000]. Compared between the two groups and two subgroups respectively, there were no statistically significant differences on length of ICU stay, infection complication rate, advanced treatment rate and mortality. Conclusions:For SAP patients with abdominal fluid, APD in the early stage could shorten the duration of SIRS, decrease intra-abdominal pressure rapidly, improve inflammatory indicators, but could not improve the clinical outcome.
ABSTRACT
Objective To study the impact of early abdominal paracentesis drainage (APD) on the clinical course in patients with severe acute pancreatitis and massive peritoneal effusion.Methods From January 2012 to January 2017,107 patients with severe acute pancreatitis treated at the Chengdu Military General Hospital were retrospective studied.According to whether the patients underwent abdominal paracentesis drainage within a week of hospital admission,they were divided into the APD group (n=66) and the Non-APD group (n=41).The APD group was further subgrouped into the 0-2 d (within 48 h),3-5 d and 6 -7 d subgroups.The mortality rates,progression rates,length of stay,cost of stay,organ failure rates and inflammatory state of each subgroup of the APD were statistically analyzed and compared.Results 22 patients in the Non-APD group progressed in four weeks to require percutaneous catheter drainage (PCD).The rate of progression was 53.7％,and the mortality rate was 22％.In the APD group,21 patients underwent PCD treatment within 4 weeks.The rate of progression was 31.8％ and the mortality rate was 9.1％.In the APD group,the progression rate for the patients in the 0-2 d subgroup was 6.9％,and the in-hospital mortality rate was O.When compared with the other subgroups,the 0 to 2 d subgroup of patients had significantly lower progression and in-hospital mortality rates,lower hospitalization duration and hospitalization costs.These patients at 1 week after hospitalization also had significantly better inflammatory indexes,less incidence of organ failure and better disease severity scores (P＜0.05).Conclusions The results confirmed the effectiveness of APD in treating patients with severe acute pancreatitis with significant peritoneal effusion.Puncture treatment within 48 hours significantly improved prognosis of patients.The best time window of APD treatment for patients with severe acute pancreatitis with massive abdominal fluid is within 48 hours of hospitalization.
