RESUMO
Objective@#To study the clinical characteristics of sepsis with systemic capillary leak syndrome(SCLS) and to evaluate the therapeutic effect and clinical significance of fluid therapy adjusted timely in these patients.@*Methods@#The clinical data of 34 patients with sepsis and SCLS in the Department of Hepatobiliary Surgery ICU of General Hospital of People′s Liberation Army General Hospital from July 2014 to January 2016 were retrospectively analyzed.There were 21 males and 13 females, aged from 21 to 74 years, with an average age of 56.3 years.Primary disease as follows: 18 cases with severe acute pancreatitis, 7 postoperative cases of subtotal hepatectomy, 5 postoperative cases of pancreatoduodenectomy, 4 postoperative cases of cholelithiasis.These patients were divided into survival group and death group according to their 28-day survival status.The clinical data including C-reactive protein(CRP), platelets (PLT), brain natriuretic peptide (BNP), the level of arterial blood lactic acid(LAC), oxygenation index(PaO2/FiO2, OI), net fluid balance(NFB) and norepinephrine dosage(NE) were collected and compared between two groups at three different intervals(day 1-3, day 4-6, day 7-9). The measurement data and numeration data were statistically analyzed with t test and χ2 test respectively to explore the inherent characteristics of the disease evolution and its clinical significance.@*Results@#The survival group (n=23)and the death group(n=11)had no significant difference in the characteristics of basic clinical characters.The condition of the survival group and the death group were both in progress in 1-3 days period manifested as increased CRP(t=-0.473, P=0.640) and BNP levels(t=0.140, P=0.895), decreased PLT counts(t=-0.505, P=0.620) in the inflammatory response, decreased LAC(t=-1.008, P=0.320) and OI level (t=-2.379, P=0.020)in tissue perfusion index, and positive fluid balance(NFB: t=0.910, P=0.370), required NE(t=-0.853, P=0.400) to maintain effective perfusion pressure with systemic edema in both groups.There was no significant difference of all these clinical parameters between the two groups.The patients′ condition of the survival group reached a plateau phase, whereas all relative indicators of the death group implied significant aggravation and deterioration of systemic infection(CRP: t=-3.438, P=0.000; PLT: t=1.649, P=0.110; BNP: t=-10.612, P=0.000), tissue perfusion (LAC: t=-11.305, P=0.000; OI: t=2.743, P=0.010)and tissue edema NFB(t=-4.257, P=0.000) and NE(t=-7.956, P=0.000) in 4-6 days period.In the last 7-9 days period the patients′ condition of the survival group took a turn for improvement, yet the condition of the death group continued to deteriorate, refractory septic shock developed and multiple organ dysfunction syndrome followed afterwards inevitably(CRP: t=-10.036, P=0.000; PLT: t=6.061, P=0.000; BNP: t=-10.119, P=0.000; LAC: t=-24.466, P=0.000; OI: t=13.443, P=0.010; NFB: t=-8.345, P=0.000; NE: t=-7.121, P=0.000).@*Conclusions@#The condition of patient with sepsis and SCLS would be improved markedly at the critical turning point around 7-9 days period since the effective systemic treatment began.If the infection does not be significantly constrolled and SCLS still remains in a sustained extravasation period in 7-9 days, the prognosis of these patients may be worse and the mortality may be higher than that of the patients mentioned before.
RESUMO
Objective@#To investigate the characteristics of spectrum and drug resistance of pathogens causing sepsis in patients with severe acute pancreatitis(SAP).@*Methods@#The clinical data of 63 SAP patients with sepsis admitted in Department of Hepatobiliary, People′s Liberation Army General Hospital from January 2014 to December 2015 were retrospectively studied. There were 47 males and 16 females, aged from 22 to 73 years, with an average age of (52±11)years. Samples were collected mainly from: (1)pancreatic and peripancreatic necrosis and abdominal drainage; (2)bile; (3) blood or deep venous catheter; (4) sputum and tracheal catheter and thoracic drainage; (5) urine. Strain identification and drug-resistance test were preformed on positive specimens.@*Results@#Of 244 pathogenic isolates, mainly derived from abdominal cavity(36.0%), blood stream (14.0%), central venous catheter(11.8%), necrotic tissue(9.1%) and sputum(8.1%); 154(63.1%) were gram-negative bacteria, 68 cases(27.9%) were gram-positive bacteria and 22 cases(9.0%) were fungi respectively. The top six common pathogens isolated were E. coli(16.0%), E.faecium and faecalis(15.2%), P.aeruginosa(10.7%), K.pneumonia(9.8%), Acinetobacter baumanni(8.2%), Stenotrophomonas maltophilia(5.3%)respectively. The detection rate of E. coli and K. pneumonia extended-spectrum β-lactamases(ESBL) was 84.6%(33/39) and 70.8%(17/24), the resistance rate to imipeniem was 12.8% and 25.0%, to cefperazone-sulbactam was 28.2% and 29.2%. As to P. aeruginosa and Acinetobacter bacillus, the resistance rate to imipeniem was 50.0% and 75.0%, to cefperazone-sulbactam was 42.3% and 70.0%; Stenotrophomonas maltophilia was completely resistant to cefperazone-sulbactam, but sensitive to minocycline, SMZ-TMP with the resistance rate less than 40.0%. Gram-positive bacterium strains mainly included E. faecium(38.2%, 26/68), E.faecalis(16.2%, 11/68) and Staphylococcus(35.3%, 24/68) which maintained high sensitivity to vancomycin, teicoplanin and linezolid, there was only one isolate resistant to vancomycin. Candida were the sole pathogens of fungal infections, sensitive to common antifungal drugs overall.@*Conclusions@#The gram-negative bacteria are the predominant pathogens mainly including ESBL-producing isolates(E.coli and K. pneumonia) and non-fermentation bacteria(P.aeruginosa and Acinetobacter bacillus) causing sepsis in SAP. The infection rate and drug-resistance rate of these two kinds of pathogens are relatively higher.
RESUMO
Objective@#To investigate the therapeutic efficacy and safety of laparoscopic radiofrequency ablation (LRFA) for specific-location hepatocellular carcinoma.@*Methods@#To retrospectively analyze 496 patients with specific-location hepatocellular carcinoma treated with LRFA from January 2010 to January 2015 in our hospital. There was a total of 652 hepatic lesions with a mean diameter of (2.8±1.3) cm including 397 cases with single lesion and 99 cases with multiple lesions. The hepatic lesions were adjacent to major hepatic vessels, hepatic hilar region, diaphragmatic dome, gallbladder, or gastrointestinal tract and on the surface of the liver, respectively.@*Results@#The 496 patients with 652 hepatic lesions were treated with LRFA successfully.The mean operation time was (48.2±9.6) minutes and the mean LRFA time per lesion was (30.3±8.6) minutes. No severe complications such as bleeding, bile leakage, gastrointestinal tract damage, diaphragmatic injury and liver function failure occurred after operation. The complete necrosis rate of the specific-location hepatocellular carcinomas was 78.4% (389/496) in one month after RFA, partially necrosis rate was 21.6% (107/496) and overall necrosis rate was 100%. In addition, the 1- and 3-year overall survivals (OS) were 95.6% and 88.5%, and progression free survivals (DFS) were 87.9% and 80.8%, respectively.@*Conclusions@#LRFA is a safe, effective, economic and minimally-invasive therapeutic approach for patients with specific-location hepatocelluar carcinoma and has good clinical application value.
RESUMO
Objective To summarize the clinical experience of immunosuppressive therapy for recipients suffering from psoriasis after liver transplantation. Methods Five patients diagnosed with cirrhosis or hepatocellular carcinoma (HCC)complicated with psoriasis after liver transplantation were recruited in this clinical trial. All participants were positive for serum biomarkers of hepatitis B virus (HBV). Induction therapy was adopted before surgery. Immunosuppressive regime of tacrolimus (FK506),mycophenolate mofetil (MMF)and adrenal cortical hormone (hormone) was implemented early after surgery. The hormone use was terminated within 1 week. Three cases of cirrhosis complicated with HCC due to chronic HBV infection were gradually switched to sirolimus substitution treatment within 1 month after liver transplantation. Two patients with cirrhosis were administered with FK506 with or without MMF following liver transplantation. All patients received anti-HBV therapy. Baseline data,changes in psoriasis area and severity index (PASI)score and adjustment of postoperative immunosuppressive agents were analyzed. Results Five patients undergoing transplantation were followed up until the submission date with a mean duration of (8. 3 ±1 . 5 )years and survived. Compared with preoperative values,PASI score was significantly reduced at postoperative 6 months (P<0. 05 ). Two patients with cirrhosis had recurrent psoriasis at 2 years after liver transplantation. PASI score was significantly increased and steadily declined after sirolimus substitution therapy. These patients remained physically stable and did not progress at postoperative 3 years. Three patients suffering from cirrhosis complicated with HCC presented with no recurrence of psoriasis postoperatively. Conclusions Sirolimus-based immunosuppressive therapy can effectively control the progression of psoriasis in liver transplantation recipients. Anti-HBV treatment should be simultaneously implemented for HBV positive patients.
