Severe acute pancreatitis complicated with intra-abdominal infection secondary to trauma:A case report

BACKGROUND Pancreatic trauma(PT)is rare among traumatic injuries and has a low incidence,but it can still lead to severe infectious complications,resulting in a high mortality rate.Acute pancreatitis(AP)is a common complication after PT,and when combined with organ dysfunction and sepsis,it will result in a poorer prognosis.CASE SUMMARY We report a 25-year-old patient with multiple organ injuries,including the pancreas,due to abdominal trauma,who developed necrotising pancreatitis secondary to emergency caesarean section,combined with intra-abdominal infection(IAI).The patient underwent performed percutaneous drainage,pancreatic necrotic tissue debridement,and abdominal infection foci debridement on the patient.CONCLUSION We report a case of severe AP and IAI secondary to trauma.This patient was managed by a combination of conservative treatment such as antibiotic therapy and fluid support with surgery,and a better outcome was obtained.

Different timing for abdominal paracentesis catheter placement and drainage in severe acute pancreatitis complicated by intraabdominal fluid accumulation

BACKGROUND Non-surgical methods such as percutaneous drainage are crucial for the treatment of patients with severe acute pancreatitis(SAP).However,there is still an ongoing debate regarding the optimal timing for abdominal paracentesis catheter place-ment and drainage.AIM To explore the influence of different timing for abdominal paracentesis catheter placement and drainage in SAP complicated by intra-abdominal fluid accumu-lation.METHODS Using a retrospective approach,184 cases of SAP complicated by intra-abdominal fluid accumulation were enrolled and categorized into three groups based on the timing of catheter placement:group A(catheter placement within 2 d of symptom onset,n=89),group B(catheter placement between days 3 and 5 after symptom onset,n=55),and group C(catheter placement between days 6 and 7 after symptom onset,n=40).The differences in progression rate,mortality rate,and the number of cases with organ dysfunction were compared among the three groups.RESULTS The progression rate of group A was significantly lower than those in groups B and groups C(2.25%vs 21.82%and 32.50%,P<0.05).Further,the proportion of patients with at least one organ dysfunction in group A was significantly lower than those in groups B and groups C(41.57%vs 70.91%and 75.00%,P<0.05).The mortality rates in group A,group B,and group C were similar(P>0.05).At postoperative day 3,the levels of C-reactive protein(55.41±19.32 mg/L vs 82.25±20.41 mg/L and 88.65±19.14 mg/L,P<0.05),procalcitonin(1.36±0.51 ng/mL vs 3.20±0.97 ng/mL and 3.41±0.98 ng/mL,P<0.05),tumor necrosis factor-alpha(15.12±6.63 pg/L vs 22.26±9.96 pg/L and 23.39±9.12 pg/L,P<0.05),interleukin-6(332.14±90.16 ng/L vs 412.20±88.50 ng/L and 420.08±87.65ng/L,P<0.05),interleukin-8(415.54±68.43 ng/L vs 505.80±66.90 ng/L and 510.43±68.23ng/L,P<0.05)and serum amyloid A(270.06±78.49 mg/L vs 344.41±81.96 mg/L and 350.60±80.42 mg/L,P<0.05)were significantly lower in group A compared to those in groups B and group C.The length of hospital stay in group A was significantly lower than those in groups B and group C(24.50±4.16 d vs 35.54±6.62 d and 38.89±7.10 d,P<0.05).The hospitalization expenses in group A were also significantly lower than those in groups B and groups C[2.70(1.20,3.55)ten-thousand-yuan vs 5.50(2.98,7.12)ten-thousand-yuan and 6.00(3.10,8.05)ten-thousand-yuan,P<0.05).The incidence of complications in group A was markedly lower than that in group C(5.62%vs 25.00%,P<0.05),and similar to group B(P>0.05).CONCLUSION Percutaneous catheter drainage for the treatment of SAP complicated by intra-abdominal fluid accumulation is most effective when performed within 2 d of onset.

Abdominal paracentesis drainage ameliorates severe acute pancreatitis in rats by regulating the polarization of peritoneal macrophages

AIM To investigate the role of peritoneal macrophage(PM) polarization in the therapeutic effect of abdominal paracentesis drainage(APD) on severe acute pancreatitis(SAP).METHODS SAP was induced by 5% Na-taurocholate retrograde injection in Sprague-Dawley rats. APD was performed by inserting a drainage tube with a vacuum ball into the lower right abdomen of the rats immediately after the induction of SAP. To verify the effect of APD on macrophages, PMs were isolated and cultured in an environment, with the peritoneal inflammatory environment simulated by the addition of peritoneal lavage in complete RPMI 1640 medium. Hematoxylin and eosin staining was performed. The levels of pancreatitis biomarkers amylase and lipase as well as the levels of inflammatory mediators in the blood and peritoneal lavage were determined. The polarization phenotypes of the PMs were identified by detecting the marker expression of M1/M2 macrophages via flow cytometry, qPCR and immunohistochemical staining. The protein expression in macrophages that had infiltrated the pancreas was determined by Western blot.RESULTS APD treatment significantly reduced the histopathological scores and levels of amylase, lipase, tumor necrosis factor-α and interleukin(IL)-1β, indicating that APD ameliorates the severity of SAP. Importantly, we found that APD treatment polarized PMs towards the M2 phenotype, as evidenced by the reduced number of M1 macrophages and the reduced levels of proinflammatory mediators, such as IL-1β and L-selectin, as well as the increased number of M2 macrophages and increased levels of anti-inflammatory mediators, such as IL-4 and IL-10. Furthermore, in an in vitro study wherein peritoneal lavage from the APD group was added to the cultured PMs to simulate the peritoneal inflammatory environment, PMs also exhibited a dominant M2 phenotype, resulting in a significantly lower level of inflammation. Finally, APD treatment increased the proportion of M2 macrophages and upregulated the expression of the anti-inflammatory protein Arg-1 in the pancreas of SAP model rats.CONCLUSION These findings suggest that APD treatment exerts antiinflammatory effects by regulating the M2 polarization of PMs, providing novel insights into the mechanism underlying its therapeutic effect.

Effect of Early Hemofiltration on Pro- and Anti-inflammatory Responses and Multiple Organ Failure in Severe Acute Pancreatitis

The effects of early hemofiltration on the serum levels of cytokines, pro- and anti-inflammatory balance and organ function in pigs with severe acute pancreatits (SAP) were studied. SAP pig model was induced by retrograde injection of artificial bile into the pancreatic duct. The pigs were randomly divided into SAP hemofiltration treatment group (HF group, n=8) and SAP non-hemofiltration treatment group (NHF group, n=8). In the HF group, the animals were subjected to high-volume and zero-balance hemofiltration therapy. The results showed that as compared with NHF group, MAP, CVP and PaO 2/FiO 2 were significantly increased (P<0.01), while HR, urinary protein content, serum ALT level, pulmonary coefficient and lung wet/dry ratio obviously decreased (P<0.05) in HF group. Under a light microscope, the pulmonary histologic scoring was lower that in HF group (P<0.01) and the lesions of renal and liver tissues were milder. However, there was no significant difference in the pancreatic histologic scoring between the two groups. Six h after establishment of the model, the serum levels of TNF-α, IL-1β were lower, while the IL-10/TNF-α ratio was higher in HF group (all P<0.05). It was suggested that early hemofiltration could effectively remove the serum cytokines TNF-α and IL-1β in SAP pigs, elevate the ratio of IL-10/TNF-α, improve hemodynamics and alleviate the lesions of lung, kidney and liver tissues.

Treatment of abdominal compartment syndrome in severe acute pancreatitis patients with traditional Chinese medicine

AIM: To investigate the therapeutic effect of traditional Chinese traditional medicines Da Cheng Qi Decoction (Timely-Purging and Yin-Preserving Decoction) and Glauber's salt combined with conservative measures on abdominal compartment syndrome (ACS) in severe acute pancreatitis (SAP) patients. METHODS: Eighty consecutive SAP patients, admitted for routine non-operative conservative treatment, were randomly divided into study group and control group (40 patients in each group). Patients in the study group received Da Cheng Qi Decoction enema for 2 h and external use of Glauber's salt, once a day for 7 d. Patients in the control group received normal saline (NS) enema. Routine non-operative conservative treatments included non-per os nutrition (NPON), gastrointestinal decompression, life support, total parenteral nutrition (TPN), continuous peripancreatic vascular pharmaceutical infusion and drug therapy. Intra-cystic pressure (ICP) of the two groups was measured during treatment. The effectiveness and outcomes of treatment were observed and APACHE Ⅱ scores were applied in analysis. RESULTS: On days 4 and 5 of treatment, the ICP was lower in the study group than in the control group(P < 0.05). On days 3-5 of treatment, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores for the study and control groups were significantly different (P < 0.05). Both the effectiveness and outcome of the treatment with Da Cheng Qi Decoction on abdominalgia, burbulence relief time, ascites quantity, cyst formation rate and hospitalization time were quite different between the two groups (P < 0.05). The mortality rate for the two groups had no significant difference. CONCLUSION: Da Cheng Qi Decoction enema and external use of Glauber's salt combined with routine non-operative conservative treatment can decrease the intra-abdominal pressure (IAP) of SAP patients and have preventive and therapeutic effects on abdominal compartment syndrome of SAP.

Abdominal paracentesis drainage attenuates intestinal inflammation in rats with severe acute pancreatitis by inhibiting the HMGB1-mediated TLR4 signaling pathway

BACKGROUND Our previous studies confirmed that abdominal paracentesis drainage(APD)attenuates intestinal mucosal injury in rats with severe acute pancreatitis(SAP),and improves administration of enteral nutrition in patients with acute pancreatitis(AP).However,the underlying mechanisms of the beneficial effects of APD remain poorly understood.AIM To evaluate the effect of APD on intestinal inflammation and accompanying apoptosis induced by SAP in rats,and its potential mechanisms.METHODS SAP was induced in male adult Sprague-Dawley rats by 5%sodium taurocholate.Mild AP was induced by intraperitoneal injections of cerulein(20μg/kg body weight,six consecutive injections).Following SAP induction,a drainage tube connected to a vacuum ball was placed into the lower right abdomen of the rats to build APD.Morphological changes,serum inflammatory mediators,serum and ascites high mobility group box protein 1(HMGB1),intestinal barrier function indices,apoptosis and associated proteins,and toll-like receptor 4(TLR4)signaling molecules in intestinal tissue were assessed.RESULTS APD significantly alleviated intestinal mucosal injury induced by SAP,as demonstrated by decreased pathological scores,serum levels of D-lactate,diamine oxidase and endotoxin.APD reduced intestinal inflammation and accompanying apoptosis of mucosal cells,and normalized the expression of apoptosis-associated proteins in intestinal tissues.APD significantly suppressed activation of the intestinal TLR4 signaling pathway mediated by HMGB1,thus exerting protective effects against SAP-associated intestinal injury.CONCLUSION APD improved intestinal barrier function,intestinal inflammatory response and accompanying mucosal cell apoptosis in SAP rats.The beneficial effects are potentially due to inhibition of HMGB1-mediated TLR4 signaling.

Embryonic natural orifice transluminal endoscopic surgery in the treatment of severe acute pancreatitis complicated by abdominal compartment syndrome

BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery(ENOTES) in treating severe acute pancreatitis(SAP) complicated with abdominal compartment syndrome(ACS).METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared.RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II(APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day(P<0.05). The cure rate was 96.87% in the ENOTES group, which was statistically different from 78.12% in the operative group(P<0.05). There were significant differences in complications and mortality between the two groups(P<0.01).CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

Continuous regional arterial infusion and laparotomic decompression for severe acute pancreatitis with abdominal compartment syndrome

AIM:To evaluate the therapeutic effects of abdominal decompression plus continuous regional arterial infusion(CRAI) via a drug delivery system(DDS) in severe acute pancreatitis(SAP) patients with abdominal compartment syndrome(ACS).METHODS:We presented our recent experience in 8 patients with SAP.The patients developed clinical ACS,which required abdominal decompression.During the operation,a DDS was inserted into the peripancreatic artery(the catheter was inserted from the right gastroepiploic artery until it reached the junction between the pancreaticoduodenal and gastroduodenal artery).Through this DDS,a protease inhibitor,antibiotics and octreotide were infused continuously.The duration of the regional artery infusion ranged from 8 to 41 d.The outcomes and the changes in the APACHE Ⅱ score,computed tomography(CT) severity index and intraabdominal pressure(IAP) of the patients were retrospectively evaluated.RESULTS:Eight patients with an initial APACHE Ⅱ score of 18.9(range,13-27) and a Balthazar CT severity index of 9.1(range,7-10) developed severe local and systemic complications.These patients underwent subsequent surgical decompression and CRAI therapy because of intra-abdominal hypertension(IAH).After a mean interval of 131.9 ± 72.3 d hospitalization,7 patients recovered with decreased APACHE Ⅱ scores,CT severity indexes and IAP.The mean APACHE Ⅱ score was 5.4(range,4-8),the CT severity index was 2.3(range,1-3),and IAP decreased to 7.7 mmHg(range,6-11 mmHg) 60 d after operation.One patient died of multiple organ failure 1 wk after surgery.CONCLUSION:CRAI and laparotomic decompression might be a therapeutic option for SAP patients with ACS.

Anterior abdominal abscess-a rare manifestation of severe acute pancreatitis:A case report

BACKGROUND Severe acute pancreatitis(SAP)is a common critical disease of the digestive system.In addition to the clinical manifestations and biochemical changes of acute pancreatitis,SAP is also accompanied by organ failure lasting more than 48 h.SAP is characterized by focal or extensive pancreatic necrosis,hemorrhage and obvious inflammation around the pancreas.The peripancreatic fat space,fascia,mesentery and adjacent organs are often involved.The common local complications include acute peripancreatic fluid collection,acute necrotic collection,pancreatic pseudocyst,walled off necrosis and infected pancreatic necrosis.After reviewing the literature,we found that in very few cases,SAP patients have complications with anterior abdominal wall abscesses.CASE SUMMARY We report a 66-year-old Asian male with severe acute pancreatitis who presented with intermittent abdominal pain and an increasing abdominal mass.The abscess spread from the retroperitoneum to the anterior abdominal wall and the right groin.In the described case,drainage tubes were placed in the retroperitoneal and anterior abdominal wall by percutaneous puncture.After a series of symptomatic supportive therapies,the patient was discharged from the hospital with a retroperi-toneal drainage tube after the toleration of oral feeding and the improvement of nutritional status.CONCLUSION We believe that patients with SAP complicated with anterior abdominal abscess can be treated conservatively to avoid unnecessary exploration or operation.

Intra-abdominal pressure monitoring in predicting outcome of patients with severe acute pancreatitis

BACKGROUND: Severe acute pancreatitis (SAP) is a serious disease with many complications, high mortality and poor prognosis. It is characterized by rapid deterioration and poses one of the most difficult challenges in clinical practice. Previous investigations suggest that SAP is one of the main causes of intra-abdominal pressure (IAP) increase. The aim of this study was to evaluate the utility of IAP-monitoring in predicting the severity and prognosis of SAP. METHODS: Eighty-nine patients with SAP who had been treated from February 2001 to December 2005 were studied. Since bladder pressure accurately reflects IAP, we measured it instead of IAP. Bladder pressure was measured at the time of admission and every 12 hours in the course of the disease, 9 consecutive times in all. The APACHE II scores of all patients were obtained within 24 hours after admission. According to a maximum bladder pressure <10 cmH(2)O, all patients were divided into two groups, mildly-elevated and severely-elevated. Mortality and mean APACHE II scores in the two groups were calculated. In addition, the mean bladder pressure and APACHE II scores in survivors were compared with those in deaths. RESULTS: Sixty-eight of the 89 patients were in the severely-elevated group. Mortality and mean APACHE II scores in this group were much higher than those in the mildly-elevated group (mortality, 39.71% vs. 9.52%; mean APACHE II score, 23.15 +/- 7.42 vs. 15.95 +/- 5.35, P<0.01). The mean bladder pressures and APACHE II scores in deaths were significantly greater than those in survivors (mean bladder pressure, 14.1 +/- 3.8 vs. 9.2 +/- 2.3 cmH(2)O, P<0.01; mean APACHE II score, 27.83 +/- 4.87 vs. 18.37 +/- 6.74, P<0.01). CONCLUSION: It is suggested that IAP may be used as a marker of the severity and prognosis of SAP.

Sequential blood purification therapy for critical patients with hyperlipidemic severe acute pancreatitis

AIM: To evaluate the efficacy of sequential blood purification therapy in the treatment of critical patients with hyperlipidemic severe acute pancreatitis.METHODS: Thirty-one intensive care unit(ICU) patients with hyperlipidemic severe acute pancreatitis treated at the Second Affiliated Hospital of Harbin Medical University were divided into either a study group(n = 15; July 1, 2012 to June 30, 2014) or a control group(n = 16; July 1, 2010 to June 30, 2012) based on the implementation of sequential blood purification therapy. The control group received continuous venous-venous hemofiltration(CVVH) on the basis of conventional treatments, and the therapeutic dose of CVVH was 30 m L/kg per hour. The study group received sequential plasma exchange and CVVH on the basis of conventional treatments. The anticoagulation regimen of CVVH is the regional citrate anticoagulation. Mortality rate on day 28, rates of systemic and local complications, duration of ICU, and time to target serum lipid level, as well as physiologic and laboratory indices were compared between the two groups.RESULTS: The mortality rate on day 28 was significantly lower in the study group than in the control group(13.33% vs 37.50%; P < 0.05). The duration of ICU stay was significantly shorter in the study group than in the control group(7.4 ± 1.35 d vs 9.19 ± 2.99 d, P < 0.05). The time to target serum lipid level was significantly shorter in the study group than in the control group(3.47 ± 0.52 d vs 7.90 ± 1.14 d, P < 0.01). There were no significant differences in the rates of systemic complications and local complications between the two groups(60% vs 50% and 80% vs 81%, respectively). In the comparisons of physiologic and laboratory indices, serum albumin and C-reactive protein were significantly better in the study group than in the control group after treatment(37.8 ± 4.6 g/L vs 38.9 ± 5.7 g/L, and 20.5 ± 6.4 mg/L vs 28.5 ± 7.1 mg/L, respectively, both P < 0.05). With the exception of plateletcrit, no other indices showed significant differences between the two groups.CONCLUSION: Sequential blood purification therapy is effective in the treatment of ICU patients with hyperlipidemic severe acute pancreatitis and can improve patient prognosis.

Abdominal paracentesis drainage ameliorates myocardial injury in severe experimental pancreatitis rats through suppressing oxidative stress

BACKGROUND Abdominal paracentesis drainage(APD)is a safe and effective strategy for severe acute pancreatitis(SAP)patients.However,the effects of APD treatment on SAPassociated cardiac injury remain unknown.AIM To investigate the protective effects of APD on SAP-associated cardiac injury and the underlying mechanisms.METHODS SAP was induced by 5%sodium taurocholate retrograde injection in Sprague-Dawley rats.APD was performed by inserting a drainage tube with a vacuum ball into the lower right abdomen of the rats immediately after SAP induction.Morphological staining,serum amylase and inflammatory mediators,serum and ascites high mobility group box(HMGB)1,cardiac-related enzymes indexes and cardiac function,oxidative stress markers and apoptosis and associated proteins were assessed in the myocardium in SAP rats.Nicotinamide adenine dinucleotide phosphate oxidase activity and mRNA and protein expression were also examined.RESULTS APD treatment improved cardiac morphological changes,inhibited cardiac dysfunction,decreased cardiac enzymes and reduced cardiomyocyte apoptosis,proapoptotic Bax and cleaved caspase-3 protein levels.APD significantly decreased serum levels of HMGB1,inhibited nicotinamide adenine dinucleotide phosphate oxidase expression and ultimately alleviated cardiac oxidative injury.Furthermore,the activation of cardiac nicotinamide adenine dinucleotide phosphate oxidase by pancreatitis-associated ascitic fluid intraperitoneal injection was effectively inhibited by adding anti-HMGB1 neutralizing antibody in rats with mild acute pancreatitis.CONCLUSION APD treatment could exert cardioprotective effects on SAP-associated cardiac injury through suppressing HMGB1-mediated oxidative stress,which may be a novel mechanism behind the effectiveness of APD on SAP.

Prevalence and risk factors of organ failure in patients with severe acute pancreatitis

BACKGROUND： This study was undertaken to determine the prevalence of organ failure and its risk factors in patients with severe acute pancreatitis （SAP） .METHODS： A retrospective analysis was made of 186 patients with SAP who were had been hospitalized in the intensive care unit of Jinzhong First People’s Hospital between March 2000 and October 2009. The patients met the diagnostic criteria of SAP set by the Surgical Society of the Chinese Medical Association in 2006. The variables collected included age, gender, etiology of SAP, the number of comorbidit, APACHEII score, contrast-enhanced CT （CECT） pancreatic necrosis, CT severity index （CTSI） , abdominal compartment syndrome （ACS） , the number of organ failure, and the number of death. The prevalence and mortality of organ failure were calculated. The variables were analyzed by unconditional multivariate logistic regression to determine the independent risk factors for organ failure in SAP.RESULTS： Of 186 patients, 96 had organ failure. In the 96 patients, 47 died. There was a significant association among the prevalence of organ failure and age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis, CTSI, and ACS. An increase in age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis were correlated with increased number of organ failure. Age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis, CTSI and ACS were assessed by unconditional multivariate logistic regression.CONCLUSIONS： Organ failure occurred in 51.6% of the 186 patients with SAP. The mortality of SAP with organ failure was 49.0%. Age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis, CTSI and ACS are independent risk factors of organ failure.

Risk factors of infected pancreatic necrosis secondary to severe acute pancreatitis

BACKGROUND： Severe acute pancreatitis（SAP） remains a clinical challenge with considerable morbidity and mortality.An early identification of infected pancreatic necrosis（IPN）, a life-threatening evolution secondary to SAP, is obliged for a more preferable prognosis. Thus, the present study was conducted to identify the risk factors of IPN secondary to SAP. METHODS： The clinical data of patients with SAP were retrospectively analyzed. Univariate and multivariate logistic regression analyses were sequentially performed to assess the associations between the variables and the development of IPN secondary to SAP. A receiver operating characteristic（ROC） curve was created for each of the qualified independent risk factors. RESULTS： Of the 115 eligible patients, 39（33.9%） progressed to IPN, and the overall in-hospital mortality was 11.3%（13/115）.The early enteral nutrition（EEN）（P=0.0092, OR=0.264）, maximum intra-abdominal pressure（IAP）（P=0.0398, OR=1.131）and maximum D-dimer level（P=0.0001, OR=1.006） in the first three consecutive days were independent risk factors associated with IPN secondary to SAP. The area under ROC curve（AUC） was 0.774 for the maximum D-dimer level in the first three consecutive days and the sensitivity was 90% and the specificity was 58% at a cut-off value of 933.5 μg/L; the AUC was 0.831 for the maximum IAP in the first three consecutive days and the sensitivity was 95% and specificity was 58%at a cut-off value of 13.5 mm Hg. CONCLUSIONS： The present study suggested that the maximum D-dimer level and/or maximum IAP in the first three consecutive days after admission were risk factors of IPN secondary to SAP; an EEN might be helpful to prevent the progression of IPN secondary to SAP.

Experience in Diagnosis and Treatment of Bleeding Complications in Severe Acute Pancreatitis by TAE

Summary: The experience in diagnosis and treatment of bleeding complications in severe acute pancreatitis (SAP) by transcatheter arterial embolization was summarized. The clinical data of 19 SAP patients complicated with intra-abdominal bleeding in our hospital from Jan. 2000 to Jan. 2003 were analyzed retrospectively and the therapeutic outcome of TAE was evaluated statistically. The results showed that the short-term successful rate of hemostasis by TAE was 89.5 % (17/19), the incidence of re-bleeding after TAE was 36.8 % (7/19) and the successful rate of hemostatis by second TAE was 71.4 % (5/7). It was concluded that the intra-abdominal bleeding in SAP was mainly caused by the rupture of erosive/infected pseudoaneurysm. Mostly, the broken vessels were splenic artery and gastroduodenal artery. In terms of emergence hemostatis, TAE is the most effective method. Surgical hemostasis is necessary if hemostasis by TAE is failed or re-bleeding occurs after TAE.

目的探讨血液滤过联合机械通气治疗重症急性胰腺炎(SAP)致急性呼吸窘迫综合征(ARDS)的临床疗效。方法选取2019年7月至2021年7月中国人民解放军联勤保障部队第九六七医院收治的70例SAP致ARDS患者作为研究对象,采用抽签法分为对照组与观察组,每组35例。对照组予以气管插管机械通气治疗,观察组在对照组治疗基础上给予血液滤过治疗。比较两组治疗前后炎症指标、临床指标、症状改善时间、呼吸机相关肺炎发生率及病死率。结果治疗后,观察组白细胞介素-10(IL-10)、白血胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)、C反应蛋白(CRP)水平均低于对照组,差异有统计学意义(P<0.05)。观察组机械通气时间、ICU住院时间及总住院时间均短于对照组,差异有统计学意义(P<0.05)。观察组腹痛、淀粉酶及胰腺水肿改善时间均短于对照组,差异有统计学意义(P<0.05)。观察组呼吸机相关肺炎发生率低于对照组,差异有统计学意义(P<0.05);两组病死率比较差异无统计学意义。结论在SAP致ARDS患者治疗中,以机械通气治疗为基础,联合血液滤过治疗效果理想,可有效抑制患者血液循环中炎症因子过度表达,抑制疾病进展性发展,可缩短机械通气治疗时间及住院时间,降低呼吸机相关肺炎发生率,值得临床进一步推广应用。
