ABSTRACT
Objective:To investigate clinical outcome and the risk factors for death in acute pancreatitis (AP) patients complicated with acute kidney injury (AKI).Methods:The clinical data of 232 AP patients complicated with AKI admitted to the Center of Severe Pancreatitis of Jinling Hospital Affiliated to Nanjing University School of Medicine from January 2016 to December 2020 were retrospectively analyzed. Patients were divided into survival group ( n=162) and death group ( n=70) based on the survival status. The two groups' clinical characteristics, biochemical indexes, and renal function indexes were compared. Univariate analysis and multivariate logistic regression analysis were used to analyze the independent risk factors for death in AP patients complicated with AKI. Results:Sixteen patients(6.9%) among the 232 had AKI Ⅰ, 15(6.5%) had AKI Ⅱ, and 201(86.6%) had AKI Ⅲ. Forty-one patients (17.7%) became AKI with a disease course <7 days, 184 patients (79.3%) gradually progressed to acute kidney disease with a disease course of 7-90 days, and 7 patients (3.0%) eventually progressed to chronic kidney disease with a disease course >90 days. Renal replacement treatment (RRT) was administered in 179 patients (77.2%), lasting an average of 14 (7-25) days. 138 patients (59.5%) had their renal function recovered while they were hospitalized, including 9 patients (6.5%) who did so within 7 days, 69 patients (50.0%) within 30 days, and 127 patients (92.0%) within 90 days. The average recovery time was 16 (7-28) days. Seventy patients (30.2%) died during hospitalization, including 8(3.5%) within 7 days, 42(18.1%) within 30 days, and 68(29.3%) within 90 days. Univariate analysis revealed that the proportions of biliary etiology, neutrophil to lymphocyte ratio (NLR), serum cystatin C, sequential organ failure assessment(SOFA) score, AKI Ⅲ proportion, number of patients undergoing RRT, and duration of AKI were significantly higher in the death group compared to the survival group. The number of patients complicated by infected pancreatic necrosis (IPN) and having surgical intervention was also significantly greater than that in the survival group, while the proportion of patients whose renal function recovered was much lower than that in the survival group. The differences were all statistically significant (all P value <0.05). Multivariate logistic analysis showed that SOFA( OR=1.182, 95% CI 1.000-1.396, P=0.049), and IPN( OR=8.403, 95% CI 3.748-18.838, P<0.001) were independent risk factors for death. Conclusions:SOFA score and IPN at admission were independent risk factors for death in AP patients with AKI. Vigilance should be given as soon as possible to improve the outcome of patients through clinical intervention.
ABSTRACT
Objective:To investigate the clinical characteristics and influencing factors of mortality in patients with intra-abdominal candidiasis (IAC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 203 IAC patients who were admitted to 7 medical centers from June 2018 to June 2020 were collected, including 54 cases in Sir Run Run Shaw Hospital of Zhejiang University School of Medicine, 31 cases in Fujian Medical University Union Hospital, 25 cases in Beijing Hospital, 25 cases in the First Affiliated Hospital of Xi'an Jiaotong University, 24 cases in China-Japan Friendship Hospital, 22 cases in General Hospital of Eastern Theater Command of Chinese PLA and 22 cases in Chongqing University Cancer Hospital. There were 130 males and 73 females, aged (64±15)years. Observation indicators: (1) candida infection and treatment of IAC patients; (2) analysis of influencing factors for mortality of IAC patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate and multivariate analyses were performed by Logistic regression model. Results:(1) Candida infection and treatment of IAC patients: 134 cases of candida albicans were cultured in the initial abdominal drainage fluid or intraoperative abdominal specimens of 203 patients, and 49 cases were treated with fluconazole. Of 69 cases infected with non candida albicans, 13 cases were treated with fluconazole. The resistance rate of candida albicans to fluconazole was 5.91%(12/203). Of 203 patients, there were 68 cases with infections shock, 53 cases with renal failure, 84 cases with respiratory failure and 63 cases with multiple organ failure, respectively. There were 148 of 203 patients admitted to intensive care unit for 9 days(range, 3-20 days), and the total hospital stay was 28 days(range, 17-50 days). Of 203 patients, 86 cases were cured and discharged, 50 cases were improved and transferred to local hospitals, 32 cases gave up treatment and discharged automatically, 19 cases died, 16 cases had no follow-up data. The mortality was 25.12%(51/203). (2) Analysis of influencing factors for mortality of IAC patients. Results of univariate analysis showed that acute physiology and chronic health evaluation score, sequential organ failure assessment score, the Cr, bilirubin, albumin, procalcitonin, and PLT on the first day of candida positive culture, of the lowest value in a week and the highest in a week, heart disease, diabetes, infections shock, renal failure, respiratory failure, multiple organ failure, anti-fungal therapy were the related factors for mortality of IAC patients ( t=-2.322, Z=-2.550, -2.262, -4.361, t=2.085, Z=-3.734, -5.226, -2.394, -5.542, t=3.462, Z=-4.957, -5.632, 3.670, -5.805, t=3.966, Z=-3.734, -5.727, χ2=4.071, 4.638, 27.353, 18.818, 13.199, 26.251, 13.388, P<0.05). Multivariate analysis showed that the bilirubin, procalcitonin on the first day of candida positive culture and infections shock were independent risk factors for mortality of IAC patients ( odds ratio=1.021, 1.022, 6.864, 95% confidence interval as 1.010-1.033, 1.001-1.044, 1.858-25.353, P<0.05). Conclusions:The common fungus of IAC was candida albicans, and fluconazole can be used as the initial empirical treatment. The prognosis of patients with abdominal candidiasis is poor. Bilirubin, procalcitonin on the first day of candida positive culture and infections shock are indepen-dent risk factors for mortality of IAC patients.

ABSTRACT
Acute pancreatitis ( AP ) is one of the common disorders of gastrointestinal system in clinical practice characterized by sudden onset, long course of disease, complex complications, severe conditions, heavy social and economic burden and the like. Recent years has seen a decreasing mortality due to the update and promotion of a series of therapeutic concepts. However, as the imbalance of comprehensive healthcare levels among different regions in China, substandard diagnosis and treatment of AP still exist, lowering the overall success rate of AP treatment. Moreover, the waste and miss of AP patients' data during the treatment period affect our original innovation in the field of AP research. Thus, after the accumulation of long-term exploration and practice, we integrated diverse data resources and established a single-disease database of AP by cooperating with computer and artificial intelligence ( AI) professionals, finished the deployment of hardware and network arrangement, generated a logical system of "business database→scientific database→sharing database", and built AP data sharing platform (www. ap-database. com), providing the fundamental functions including browse, search, upload and download ( with permissions) . We hope to share the abundant and free medical date with clinicians, computer or AI practitioners and attract communications and cooperation from different fields, which may deepen new values from current data mining and advance the research on AP.

ABSTRACT
Pancreatic fatty infiltration is defined as the deposition of excess adipose tissue (mainly consisting of triacylglyceride ) in the pancreas.Epidemiological studies have revealed that the prevalence of pancreatic fatty infiltration is high , but the research is still at a preliminary stage and there is no consensus on the relevant pathophysiological mechanisms so far .The diagnosis of pancreatic fatty infiltration relies on histopathologic examination and imaging techniques .This article reviews the recent research advances on the pancreatic fat infiltration in order to improve our understanding of the disease .
ABSTRACT
Objective To observe the clinical outcomes and safety of continuous negative pressure irrigation (NPI) and endoscopic necrosectomy(ED) for treating infected pancreatic necrosis(IPN). Methods A retrospective review of the data of 163 severe acute pancreatitis(SAP) patients with IPN who were treated by four-step drainage from January 2012 to December 2013 at the SAP therapy center of Nanjing General Hospital was performed. All patients were divided into 7 groups including PCD alone, PCD+NPI, PCD+NPI+ED, PCD+ON, PCD +NPI +ON, PCD +ED +ON and PCD +NPI +ED +ON group based on the drainage strategy of percutaneous catheter drainage(PCD),NPI, ED and open necrosectomy(ON), and the feasibility and safety were analyzed. Results All the patients underwent PCD therapy. Each patient underwent a median of 3 drainage procedures and the median total drainage duration was 11 days. No significant procedure-related complication was observed. Around 40% of the patients recovered after receiving PCD alone. Thirty-four patients(20.9%) underwent ON. The mean hospitalization duration was 38 days and the mean ICU stay was 19 days. There were 25 cases with new-onset organ functional failure,26 patients with sepsis,32 patients with gastric and intestinal fistula,34 patients with intra-abdominal bleeding,8 patients with portal vein thrombosis and 3 patients with gastric outlet obstruction. 28 patients(17.2%) died. Conclusions This four-step approach is effective in treating IPN when compared with other step-up strategies. NPI and ED could offer distinct clinical efficacy without adding no extra risk to patients.
ABSTRACT
Objective Up to the present time, no reports are seen at home or abroad on the clinical characteristics of severe acute pancreatitis (SAP) with persistent inflammation-immunosuppression-catabolism syndrome (PICS), and few studies have been conducted on the risk factors for PICS.This article summarizes the clinical characteristics of PICS in SAP patients and presents a multivariate regression analysis of its risk factors.Methods This is a retrospective study on the clinical data about 214 cases of SAP treated for over 14 days in the Surgical Intensive Care Unit (SICU) from January 1, 2014 to December 31, 2015.According to the diagnostic criteria of PICS, we divided the SAP patients into a PICS group (n=149) and a non-PICS group (n=65).We compared the systemic and pancreatitis-specific complications and mortality rates in the SICU and at 12 months after discharge.We also performed a multivariate regression analysis on the risk factors of PICS.Results The incidence rates of biliary SAP and multiple-organ dysfunction syndrome (MODS) were significantly higher in the PICS (44.3% and 93.3%) than in the non-PICS group (29.2% and 55.4%) (P=0.038).The results of multivariate regression analysis showed that the risk factors for PICS included obesity (OR=2.3;95% CI: 1.0-5.2), biliary causes (OR=4.2;95% CI: 1.4-13.0), and MODS (OR=4.4;95% CI: 1.3-14.4).The survival rate at 12 months after discharge was remarkably lower in the PICS than in the non-PICS group (88.5% vs 98.2%, P=0.036).Conclusion The incidence rate of PICS is high in SAP patients.Obesity, biliary causes and MODS are independent risk factors for PICS.The complication of PICS may be an important indicator of the poor prognosis of SAP.
ABSTRACT
Objective Acute pancreatitis exhibits different clinical and ultrasonic features in patients complicated with acute acalculous cholecystitis ( AAC) at different stages .The aim of this study was to analyze the ultrasonic characteristics of acute pancreati-tis complicated with AAC at different stages . Methods We retrospectively analyzed the clinical data about 41 cases of acute pancrea-titis with moderate to severe AAC .According to whether AAC developed within or after 2 weeks of the onset of acute pancreatitis , we divided the patients into an early-stage group (n=18) and a late-stage group (n=23).We recorded the gallbladder size, gallbladder wall thickness , fluid around the gallbladder , biliary sludge deposition and the Murphy′s sign by ultrasonography , obtained AAC-related clinical and laboratory data concerning body temperature , Murphy′s sign, WBC count and C-reactive protein level , and analyzed the ultrasonic features of AAC at different stages in the acute pancreatitis patients. Results All the patients experienced a fever of >38.5℃, 38.89%with chills in the early onset group and 47.83%in the late onset group .Increases were observed in patients of the early-and late-stage groups in the WBC count ( 94.44%vs 82.61%) , the C-reactive protein level ( 100%vs 91.30%) , and the fluid volume around the gallbladder (94.44%vs 60.86%, P<0.05), but incidence rate of gallbladder wall thickening was significantly lower in the former than in the latter group (11.11%vs 78.26%, P<0.01). Conclusion AAC developing at different stages of acute pancreatitis has different ultrasonic features , with higher incidence rates of fluid around the gallbladder in the early stage and gallbladder wall thickening in the late stage.
ABSTRACT
Objective To investigate the early diagnostic value of traditional scoring systems in critical acute pancreatitis.Methods From Jan 2007 to Ju12013,consecutive 184 patients with AP who were admitted to the surgical intensive care unit of the Institute of General Surgery,Nanjing Generai Hospital of Najing Militery Region within 72 h from the onset of the disease were studied.Patients were assigned to four groups,including mild,moderate,severe and critical AP according to the determinant based classification and the receiver operating characteristics(ROC) curve was used to predict the presence of critical AP,and Z test and logistic regression was applied to determine the diagnostic value of traditional scoring systems.Results The area under ROC (AUC) of Sofa,BISAP and CTSI score for early diagnosis of critical AP was 0.896,0.877 and 0.862;the best cut off value was 4.5,9.5 and 2.5.Moreover,the AUC of APACHE Ⅱ and Ranson score was 0.807 and 0.707,and the best cut off value was 8.5 and 3.5,respectively.Z test showed early diagnosis rate of Sofa,BISAP,CTSI score was significantly higher than that in Ranson score,and the difference between the two groups was statistically significant (P ＜ 0.05);though they were higher than APACHE Ⅱ score,the difference between the two groups was not statistically significant (P ＞ O.05).Logistic regression showed that high APACHE Ⅱ,Sofa,BISAP and CTSI score were independent risk factors for the development of critical AP (P ＜ 0.05).Conclusions Sofa,CTSI and BISAP score may be clinically important for early diagnosis of critical AP.
ABSTRACT
Toxic epidermal necrolysis (TEN) is an acute skin inflammation,which belongs to heavy drug eruption.With the extensive and widespread use of antibiotics,nonsteroidal antipyretic analgesics and other pharmacotherapies in the treatment of critically ill patients,the trend of morbidity of TEN is gradually increased,especially in intensive care unit.In consideration of the high mortality rate of TEN and its great influence on the overall prognosis of patients with critical illness,we summarized the diagnosis and treatment experiences in the management of TEN based on retrospective analysis of one patient with severe acute pancreatitis and TEN.
ABSTRACT
Objective To study the effect of mechanical ventilation guided by esophageal pressure on hemodynamics and oxygen metabolism of severe acute pancreatitis (SAP) swine model with intra-abdominal hypertension (IAH) Methods By self-controlled study,SAP model was made by infusing sodium taurocholate (5％) into the pancreatic duct in 6 domestic swine.Mechanical ventilator mode was volumeassist control with tidal volume 10 ml/kg ; FiO2 40％ and PEEP 5 cm H2O (routine ventilation) given to SAP model swine.After 3 h ventilation,pneumo-peritoneum was made with N2 gas to increase the intraabdominal pressure (IAP) to 25 mm Hg in SAP swine.Three more hours later,PEEP was adjusted as the measurement of esophageal pressure (Pes guided ventilation) to such a level that trans-pulmonary pressure stayed above 0 cm H2O during end-expiratory occlusion.During the investigation period,heart rate (HR),cardiac output index (CI),central venous pressure (CVP),mean arterial pressure (MAP) and pulmonary arterial wedge pressure (PAWP) were continuously recorded with the aid of Swan-Ganz catheter and ECG monitor,and oxygen partial pressure of artery (PaO2) and carbon dioxide partial pressure of artery (PaCO2) were measured by blood-gas analysis.In addition,systemic oxygen delivery (DO2) and systemic oxygen consumption (VO2) were calculated by using the data of blood-gas analysis of arterial and central venous blood.Results No swine model was subjected to barotrauma.After routine mechanical ventilation,there were significant differences in HR,CI,MAP,CVP,PAWP,Ppeak,Pplat,Pes,pulmonary compliance (Cstat),PaO2,and DO2 between SAP and IAH in swine (all P ＜ 0.05).Compared with routine ventilation,however,PaO2 and Cstat improved significantly with lower CI and increased Pplat after PEEP adjusted according to measurements of esophageal pressure (all P ＜ 0.05).The lactate decreased significantly after esophageal pressure guided ventilation (all P ＜ 0.05).There were no significant changes in PaCO2,HR,MAP,CVP and PAWP in IAH swine after mechanical ventilation with routine parameters (all P ＞ 0.05).Conclusions There were remarkable effects on oxygen metabolism in response to mechanical ventilation guided by esophageal pressure.In case of clinical application of mechanical ventilation,the results of this study are in favor of setting transpulmonary pressure according to measurements of esophageal pressure in SAP patients with IAH in an early stage.
ABSTRACT
Objective To investigate the management of retroperitoneal infected necrotic tissues in pelvic cavity in patients with severe acute pancreatitis (SAP).Methods The clinical data of 5 patients with SAP complicated with retroperitoneal infected necrotic tissue in the pelvic carvity who were admitted to the General Hospital of Nanjing Military Area from December 2009 to February 2012 were retrospectively analyzed.Systemic comprehensive treatement combined with local management were applied to all the patients.Results Systemic comprehensive treatment:all the 5 patients were treated by enteral nutrition,3 by mechanical ventilation and 3 by continuous blood purification.All the retroperitoneal infected necrotic tissues in the pelvic carvity were treated by computed tomography (CT)-guided percutaneous catheter drainage,and then the patients were converted to open surgery for further drainage.Four patients had complication of infected pancreatic necrosis bleeding,and they were treated by arterial embolism and (or) sandwich therapy.Local management:5 patients with retroperitoneal infected necrotic tissues received CT-guided percutaneous catheter drainage via buttocks.The average time of puncturation after illness was 38.4 days,and the average CT density of infected necrotic tissue was 24.4 Hu (20-28 Hu).Catheterization was successfully done in the open surgery for all the 5 patients,and the average time of abdominal drainage was 21 days.The body temperature and white blood cell count were decreased after puncturation.The average duration of intensive care unite stay,the average time of hospital stay and the average cost of hospitalization were (47 ± 20 )days,(88 ±34 )days and (186 342 ± 15 467 )yuan.All the patients were followed up till May 2012,no recurrece of the retroperitoneal infected necrotic tissue was detected.Conclusion CT-guided percutaneous catheter drainage via buttocks is effective for the treatment of retroperitoneal infected necrotic tissue in the pelvic cavity in SAP patients.
ABSTRACT
Infected pancreatic necrosis is a fatal complication of severe acute pancreatitis ( SAP),while traditional laparotomy has many disadvantages,such as great trauma and many complications,in recent years,minimally invasive treatment has got great progress in clearing the necrotic tissue of pancreas,but its drainage effect is not optimal.From January 2010 to December 2011,19 patients with infected pancreatic necrosis complicated by SAP who were admitted to the Nanjing General Hospital of Nanjing Military Area were implemented computed tomography or ultrasound-guided Seldinger puncture.Along the puncture needle,a guide wire was inserted into the necrotic tissue,and then the sinus was expanded,in which a tube was placed for negative pressure irrigation and drainage.By continuous postoperative negative pressure irrigation and drainage,the necrotic tissue gradually dropped off and disappeared in 12 patients,and the other 7 patients were performed endoscopic necrotic tissue removal and drainage along the sinus.Systemic symptons of infection obviously improved in all of the 19 patients,and no organ dysfunction or complications occurred.Finally,16 patients were cured and 3 patients died.Continuous percutaneous negative pressure irrigation and drainage combined with the endoscopic necrotic tissue removal could become an important choice to treat the infected pancreatic necrosis.
ABSTRACT
Objective To observe the clinical effectiveness of percutaneous catheter drainage ( PCD ) and PCD + negative pressure irrigation ( PCD + NPI ) for treatment of severe acute pancreatitis ( SAP ) patients with infective pancreatic necrosis (IPN).Methods Data of 71 IPN patients admitted from January 2010 to December 2011 were included and retrospectively analyzed.They were divided into two groups by the different treatment choices:PCD group (52 patients) and PCD + NPI group (19 patients).In PCD group,percutaneous pig-tail drainage catheter was inserted for intermittent IPN drainage,and in PCD + NPI group,negative pressure irrigation catheter was inserted for continuous IPN drainage.The indication for laparotomy surgery was no improvement after PCD or PCD + NPI for 3 days,or septic shock,abdominal cavity bleeding,digestive tract fistula occurred,the area of IPN decreased less than 1/2.Results The surgery rate of PCD +NPI group was 15.8％,which were significantly lower than that in PCD group (48.1％,P ＜0.05).7(36.8％ ) patients in PCD + NPI group received endoscopic drainage,which were significantly higher than that in PCD (0,P ＜0.05).The time interval between initial tube placement and operation in the PCD + NPI group was (22 ± 11 ) d,which were significantly longer than that in PCD group [ ( 10 ± 6 ) d,P ＜ 0.05 ].The difference of mean session and number of tube placement,number of laparotomy surgery,complications of laparotomy surgery in the two groups was not statistically significant.The mortality rate in the PCD + NPI group was 15.8％,which was not significantly higher than that in PCD group ( 13.5％ ).The ICU days,length of hospital stay and hospital costs in PCD + NPI group were lower than those in the PCD group,but the difference between the two groups was not statistically significant.Conclusions PCD + NPI can effectively reduce operation rate for patients with infective pancreatic necrosis.
ABSTRACT
BACKGROUND: As a micro-injurying and reduplicative treatment of osteoarthritis,the arthroscopic debridement has got the affirmation of numerous scholars. But as one of the standard procedures in artnroscopic debridement,synovectomy is called in question recently.OBJECTIVE: To explore the applied value of synovectomy in the arthroscopic debridement of osteoarthritis.DESIGN: Retrospective controlled analysis.SETTING: Department of Orthopaedics, Fushun Central Hospital.PARTICIPANTS: Sixty-five patients received synovectomy in the arthroscopic debridement of knee joint osteoarthritis in the Department of Orthopaedics,Fushun Central Hospital from February 1997 to December 2000.Thirty-two among them,with complete data and over 1 year's followup,were taken for synovectomy group. Forty-eight patients received the arthroscopic debridement of knee joint osteoarthritis without synovectomy in the Department of Orthopaedics,Fushun Central Hospital from January 2001 to November 2003.Thirty among them,with complete data and over 1 year's follow-up,were taken for control group.METHODS: Synovectomy was taken as the factor of intervention in the operation to perform grouping. The analysis of curative effect was performed to control with joint douching,corpus liberum removal,osteophyma cleaning,meniscus fitting,cartilage gouging,synovectomy and without synovectomy or part synovectomy. Lysholm evaluation standard of knee joint osteoarthritis was used to the knee joint functional evaluation beween preoperation and postoperative 1 year in two groups. And operative time,postoperative draining quantity,postoperative 7-day visual analog score,postoperative 1-year Lysholm score of knee joint, were recorded.MAIN OUTCOME MEASURES: Preoperative and postoperative 1-year Lysholm score of knee joint,operative time,postoperative draining quantity,postoperative 7-day visual analog score.RESULTS: Sixty-two patients were included and all of them entered the result analysis.The preoperative patients in two groups were comparable with each other and the differences of Lysholm score were not significant (t=0.127,P=0.899).The operative time was longer in synovectomy group than in control group,the differences were significant (t=9.547,P ＜ 0.001)and the postoperative draining quantity was more in synovectomy group.The postoperative visual analog score was bigger in synovectomy group than in control group and the differences were significant [the scores of synovectomy and control groups were respectively (4.6±1.1),(2.8±1.4),t=6.206,P ＜ 0.001].The differences of knee joint score in 1-year follow-up were not significant [the scores of synovectomy and control groups were respectively (77.6±11.9),(79.0± 10.3),t=0.562,P=0.576].CONCLUSION: Synovectomy can not increase the curative effect in the near future in the arthroscopic debridement of osteoarthritis. On the contrary,the operative time was longer,the operative wound was larger and postoperative reaction was more serious. It should not be used in the debridement generally.
ABSTRACT
Patients with SAP have a hypermetabolic and hypercatabolic state.Nutritional support for patients with SAP is needed.EN by the jejunal route does not stimulate pancreatic secretions and is safe.At present,the beneficeal effects of EN towards improving the nutritional condition,protecting gut barrier function,reducing translocation of bacteria and endotoxins,modulating the inflammatory response,and decreasing the cost have been observed.Therefore,the EN rather than PN should be used by the jejunal route to provide nutritional support for patients with SAP.
