RESUMO
Abstract Biliary drainage for Perihilar Cholangiocarcinoma (PCCA) can be performed either by endoscopic retrograde cholangiopancreatography or Percutaneous Transhepatic Biliary Drainage (PTBD). To date there is no consensus about which method is preferred. Taking that into account, the aim of this study is to compare Endoscopic Biliary Drainage (EBD) versus percutaneous transhepatic biliary drainage in patients with perihilar cholangiocarcinoma through a systematic review and metanalysis. A comprehensive search of multiple electronic databases was performed. Evaluated outcomes included technical success, clinical success, post drainage complications (cholangitis, pancreatitis, bleeding, and major complications), crossover, hospital length stay, and seeding metastases. Data extracted from the studies were used to calculate Mean Differences (MD). Seventeen studies were included, with a total of 2284 patients (EBD = 1239, PTBD = 1045). Considering resectable PCCA, the PTBD group demonstrated lower rates of crossover (RD = 0.29; 95% CI 0.07-0.51; p = 0.009 I2 = 90%), post-drainage complications (RD = 0.20; 95% CI 0.06-0.33; p < 0.0001; I2 = 78%), and post-drainage pancreatitis (RD = 0.10; 95% CI 0.05-0.16; p < 0.0001; I2 = 64%). The EBD group presented reduced length of hospital stay (RD = -2.89; 95% CI -3.35 - -2,43; p < 0.00001; I2 = 42%). Considering palliative PCCA, the PTBD group demonstrated a higher clinical success (RD = -0.19; 95% CI -0.27 - -0.11; p < 0.00001; I2 = 0%) and less post-drainage cholangitis (RD = 0.08; 95% CI 0.01-0.15; p = 0.02; I2 = 48%) when compared to the EBD group. There was no statistical difference between the groups regarding: technical success, post-drainage bleeding, major post-drainage complications, and seeding metastases.
RESUMO
Malignant obstructive jaundice is caused by direct invasion or compression of the biliary tract by malignant tumors of the bile duct, pancreas and other systems. Patients are often accompanied by symptoms such as malnutrition, low immune function, and organ damage. The treatments of active preoperative biliary drainage and reasonable reinfusion combined with enteral nutrition can help improve the safety of patients during the perioperative period, reduce postoperative complications, and improve the life quality of patients. This article reviewed the research progress of preoperative biliary drainage, bile recycling methods and precautions in patients with malignant obstructive jaundice, aiming to provide reference for clinical diagnosis and treatment practice.
RESUMO
Objective:To investigate the influencing of preoperative biliary drainage on surgery-related complications after pancreaticoduodenectomy.Methods:The retrospective case-control study was conducted. The clinical data of 267 patients with periampullary space-occupying lesion who were admitted to Beijing Friendship Hospital of Capital Medical University from January 2016 to July 2020 were collected. There were 166 males and 101 females, aged 61 (range, 54?84)years. Observation indicators: (1) comparison of preoperative situations in patients with and without preoperative biliary drainage; (2) comparison of intraoperative and postoperative situations in patients with and without preoperative biliary drainage; (3) methods and efficacy of preoperative biliary drainage; (4) factors influencing surgery-related complications after pancreaticoduodenec-tomy. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(rang) or M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was conducted using the corresponding statistical methods based on data type. Multivariate analysis was conducted using the Logistic stepwise regression model. Results:(1) Comparison of preoperative situations in patients with and without preoperative biliary drainage. Of the 267 patients, there were 104 cases with preoperative biliary drainage and 163 cases without preoperative biliary drainage. Cases with malignant tumor, cases with borderline tumor, cases with chronic pancreatitis were 89, 13, 2 in patients with preoperative biliary drainage, versus 111, 41, 11 in patients without preoperative biliary drainage, showing significant differences in pathology type between them ( χ2=10.652, P<0.05). (2) Comparison of intraoperative and postoperative situations in patients with and without preoperative biliary drainage. There was no significant difference in operation time, volume of intra-operative blood loss, postoperative complications, grade B pancreatic fistula, grade C pancreatic fistula, biliary leakage, abdominal or gastrointestinal bleeding, incidence of abdominal infection, white blood cell count at postoperative day 1, white blood cell count at postoperative day 3, neutrophil-to-lymphocyte ratio at postoperative day 1, neutrophil-to-lymphocyte ratio at postoperative day 3, C-reactive protein-albumin ratio at postoperative day 1, C-reactive protein-albumin ratio at post-operative day 3, duration of hospital stay between the 104 patients with preoperative biliary drainage and the 163 patients without preoperative biliary drainage ( P>0.05). (3) Methods and efficacy of preoperative biliary drainage. Of the 104 patients with preoperative biliary drainage, there were 40 cases receiving endoscopic nasobiliary drainage with drainage time as (12±2)days, there were 38 cases receiving percutaneous transhepatic cholangial drainage with drainage time as (7±1)days, and there were 26 cases receiving endoscopic retrograde biliary drainage with drainage time as (19±2)days. The total bilirubin, direct bilirubin, aspartate transaminase, alanine aminotrans-ferase in 104 patients were (223±18)μmol/L, (134±11)μmol/L, (112±10)U/L, (160±16)U/L before biliary drainage and (144±13)μmol/L, (84±8)μmol/L, (79±8)U/L, (109±12)U/L after biliary drainage, showing significant differences in the above indicators ( t=3.544, 3.608, 2.523, 2.509, P<0.05). (4) Factors influencing surgery-related complications after pancreatocoduodenectomy. Results of multi-variate analysis showed that operation time was an independent factor influencing surgery-related complications after pancreaticoduodenectomy ( odds ratio=1.005, 95% confidence interval as 1.002?1.008, P<0.05). Conclusions:Preoperative biliary drainage does not increase the incidence of complications related to pancreaticoduodenectomy in patients with periampullary space-occupying lesion. Operation time is an independent factor influencing postoperative surgery-related complications.
RESUMO
ABSTRACT Background: Acute cholangitis (AC) is a gastro-intestinal emergency associated with significant mortality. Role of change in the levels of inflammatory markers post drainage in predicting outcome in acute cholangitis is uncertain. Objective: To evaluate the predictive value of changes in C-reactive protein (CRP) and procalcitonin levels after biliary drainage in relation to outcomes (survival or mortality) at 1 month. Methods A prospective observational study of consecutive adults presenting with AC was performed. At admission and at 48 hours post biliary drainage, procalcitonin and CRP were sent. Results: Between August 2020 till December 2020 we recruited 72 consecutive patients of AC. The median age of the patients was 55 years (range 43-62 years) and 42 (58.33%) were females. Although the delta change in serum procalcitonin (P value<0.001) and CRP (P value<0.001) was significant, it had no bearing on the outcome. Altered sensorium and INR were independently associated with mortality at 1 month. The 30-day mortality prediction of day 0 procalcitonin was measured by receiver operating characteristic analysis which resulted in an area under the curve of 0.697 with a 95% confidence interval (95%CI) of 0.545-0.849. The optimal cut-off of procalcitonin would be 0.57ng/mL with a sensitivity and specificity of 80% and 60% respectively to predict mortality. Conclusion: Change in serum procalcitonin and CRP levels at 48 hours post drainage although significant, had no impact on the outcome of acute cholangitis.
RESUMO Contexto: A colangite aguda (CA) é uma emergência gastro-intestinal associada à significativa mortalidade. O papel da mudança nos níveis de marcadores inflamatórios pós drenagem na previsão do desfecho em CA é incerto. Objetivo: Avaliar o valor preditivo das alterações nos níveis de proteína reativa C (PCR) e procalcitonina após drenagem biliar em relação aos desfechos (sobrevida ou mortalidade) em um mês. Métodos Realizou-se estudo observacional prospectivo de adultos consecutivos que apresentam CA. Na admissão e após 48 horas de drenagem biliar, foram analisadas a procalcitonina e a PCR. Resultados Entre agosto de 2020 e dezembro de 2020, foram recrutados 72 pacientes consecutivos de CA. A idade mediana dos pacientes foi de 55 anos (faixa de 43 a 62 anos) e 42 (58,33%) do sexo feminino. Embora a variação delta no soro procalcitonina (valor P<0,001) e PCR (valor P<0,001) tenha sido significativa, não houve influência sobre o resultado. Sensório alterado e INR foram independentemente associados à mortalidade em 1 mês. A previsão de mortalidade de 30 dias no dia 0 da procalcitonina foi medida pela análise característica operacional receptora que resultou em uma área sob a curva de 0,697 com intervalo de confiança de 95% (IC95%) de 0,545-0,849. O corte ideal de procalcitonina seria de 0,57ng/mL com sensibilidade e especificidade de 80% e 60% respectivamente para prever a mortalidade. Conclusão: A mudança nos níveis de procalcitonina sérica e PCR em 48 horas após a drenagem, embora significativa, não teve impacto no resultado da colangite aguda.
RESUMO
Objective:To evaluate the clinical efficacy of PTCD and ERCP combined with T tube in the perioperative period of biliary anastomosis in patients with moderate to severe obstructive jaundice.Methods:The data of 93 patients with moderate obstructive jaundice who met the inclusion criteria and planned to undergo cholangiojejunostomy (including reconstruction after pancreaticoduodenectomy) in Shuguang Hospital Affiliated to Shanghai University of traditional Chinese medicine from March 2015 to December 2021 were collected. According to the perioperative drainage strategy, 54 cases were divided into PTCD group and 39 cases were divided into ERCP combined with intraoperative T-tube drainage group. Retrospective cohort method was used to analyze the bile duct diameter, postoperative hospital stay, operation cost, time of jaundice reduction, degree of jaundice reduction, average postoperative bile loss, postoperative bile leakage, abdominal infection of the two groups. The measurement data were expressed as mean ± standard deviation( ± s), and t test was used for comparison between groups. The data of skewed distribution were represented by M( Q1, Q3), and nonparametric rank sum test was used. Chi-square test was used for counting data. Results:The preoperative yellowing reduction time, operation cost, mean bile loss 7 days after operation, time to remove biliary drainage tube, and postoperative hospital stay in PTCD group were (5.9±3.1) d, (59 846.3±9 129.7) yuan, 210.0(170.0, 325.0) mL/d, (18.4±5.6) d, and(10.7±4.4) d, respectively, while those in ERCP group were (9.5±4.4) d, (77 833.1±12 164.5) yuan, 285.0(225.0, 370.0) mL/d, (41.4±17.2) d and(15.3±5.6) d, respectively. The difference between the two groups was statistically significant ( P<0.05). There was no significant difference between the two groups in general condition before drainage, cholangitis and hemorrhage after drainage, degree of jaundice reduction, bile leakage after surgery, abdominal infection, etc. Conclusions:When performing biliary enterostomy in patients with moderate or above obstructive jaundice, PTCD and ERCP combined with intraoperative T-tube drainage are effective means to improve the safety of perioperative period. PTCD has some advantages in reducing jaundice efficiency, operation cost and rapid postoperative rehabilitation.
RESUMO
Objective:To evaluate the safety and efficacy of endoscopic retrograde biliary drainage (ERBD) for acute obstructive suppurative cholangitis (AOSC) in the elderly.Methods:A retrospective analysis was performed on the clinical data of AOSC patients admitted to the First Affiliated Hospital of Xinjiang Medical University from January 2018 to January 2020. Patients aged 75 years and over ( n=49) were assigned to the elderly group and patients under 75 years old were assigned to the control group ( n=63). General data, American Society of Anesthesiologists (ASA) grading, procedure-related indicators, incidence of postoperative complications and mortality were compared. Results:There were significant differences in age (82.6±5.1 years VS 64.6±4.5 years, t=19.98, P<0.001), albumin levels (29.1±5.9 g/L VS 34.6±8.8 g/L, t=-3.94, P<0.001) and ASA grade ( χ2=8.37, P=0.015) in the elderly group and the control group . The elderly group were accompanied by more basic diseases, i.e. hypertension [57.14% (28/49) VS 34.9% (22/63), χ2=5.51, P=0.019], coronary heart disease [55.1% (27/49) VS 27.0% (17/63), χ2=9.14, P=0.003], chronic obstructive pulmonary diseases/asthma [24.5% (12/49) VS 6.3% (4/63), χ2=7.41, P=0.006]. There were no significant differences in the operation time (31.4±8.1 min VS 30.4±8.0 min, t=-0.61, P=0.543) or hospital stay (6.1±1.7 days VS 5.7±1.4 days, t=1.35, P=0.182). The incidences of postoperative complications were 14.3% (7/49) in the elderly group and 12.7% (8/63) in the control group, showing no significant difference ( χ2=0.06, P=0.807). No ERBD-related death was observed in either group during hospital stay. Conclusion:For elderly patients with AOSC over 75 years old, emergency ERBD, which can quickly relieve the disease, is safe and effective. Advanced age is not an absolute contraindication for emergency ERBD.
RESUMO
Objective:To evaluate the safety and feasibility of double endoscopic bypass, namely endoscopic ultrasound-guided gastroenterostomy (EUS-GE) combined with endoscopic ultrasound-guided biliary drainage (EUS-BD), for malignant gastric outlet and biliary obstruction.Methods:A retrospective analysis was conducted on data of 10 patients with malignant gastric outlet and biliary obstruction who were not suitable for surgery or endoscopic retrograde cholangiopancreatography (ERCP) and treated by double endoscopic bypass in Nanjing Drum Tower Hospital from August 2017 to October 2020. The completion of therapy, clinical efficacy and post-procedure adverse events were analyzed.Results:Ten patients with different malignant cancer successfully underwent EUS-GE and EUS-BD, with procedure time of 60.5±22.3 min (30-100 min). There were no postoperative adverse events. EUS-GE was clinically successful in all 10 cases. Of the 10 EUS-BD cases, 9 were clinically successful, and 1 did not meet the criteria of clinical success. The median follow-up was 71 (37-120) days. None of the 10 patients had recurrent gastric outflow tract obstruction or biliary tract obstruction.Conclusion:Double endoscopic bypass is feasible and effective for patients with malignant gastric outlet and biliary obstruction and without surgery or ERCP opportunity.
RESUMO
Objective:To evaluate the effect of different options of preoperative biliary drainage (PBD) on perioperative complications of patients undergoing pancreaticoduodenectomy (PD).Methods:The clinical data of patients undergoing PD for periampullary carcinoma from January 2016 to November 2021 at Third Affiliated Hospital of Naval Medical University (Shanghai Eastern Hepatobiliary Surgery Hospital) were retrospectively analyzed. The 303 patients including 199 males and 104 females, aged (64.2±8.8) years. According to PBD, the patients were divided into two groups: percutaneous transhepatic biliary drainage (PTBD) group ( n=228) and endoscopic retrograde cholangiopancreatography (ERCP) group ( n=75). PBD operation-related complications (including bleeding, biliary leakage, etc.), postoperative complications of PD (including pancreatic fistula, biliary leakage, surgical site infection, etc.) and perioperative complications (PBD operation-related complications + postoperative complications of PD) were compared between the two groups. Univariate and multivariate logistic regression analysis were used to analyze factors influencing perioperative complications of PD. Results:The incidence of PBD operation-related complications in PTBD group was 10.1% (23/228), lower than that in ERCP group 25.3%(19/228), and the difference was statistically significant (χ 2=10.99, P=0.001). The incidence of postoperative complications of PD in PTBD group was 38.2%(87/228), lower than that in ERCP group 69.3%(52/75), the difference was statistically significant (χ 2=22.09, P<0.001). The incidence of total perioperative complications in PTBD group was 44.3% (101/228), lower than that in ERCP group 73.3%(55/75), the difference was statistically significant (χ 2=19.05, P<0.001). Multivariate logistic regression analysis showed that patients with periampullary carcinoma undergoing ERCP biliary drainage and PD had increased risk of surgical site infection ( OR=2.86, 95% CI: 1.59-5.16, P<0.001) and pancreatic fistula ( OR=3.06, 95% CI: 1.21-7.74, P=0.018). Conclusion:ERCP biliary drainage is a risk factor for postoperative pancreatic fistula and surgical site infection in patients with periampullary carcinoma undergoing PD. PTBD should be recommended as the first choice for the patients underwent PD.
RESUMO
Objective:To investigate the effects of different preoperative biliary drainage methods on bile bacterial culture and drug resistence of malignant obstructive jaundice.Methods:The retrospective and descriptive study was conducted. The clinical data of 317 patients with malignant obstructive jaundice who were admitted to the First Medical Center of Chinese PLA General Hospital from January 2015 to December 2018 were collected. There were 216 males and 101 females, aged (62±10)years. Of 317 patients, 158 cases had no preoperative biliary drainage, 115 received preoperative biliary drainage by percutaneous transhepatic choledochal drainage (PTCD), 44 received preoperative biliary drainage by endoscopic retrograde biliary drainage (ERBD). Observation indicators: (1) bile bacteria in different preoperative biliary drainage methods; (2) clinicopathological characteristics of patients with positive bile bacteria; (3) drug resistance of bile bacteria in different methods of preoperative biliary drainage. Measurement data with normal distribution were expressed as Mean± SD. Count data were expressed as absolute numbers or percen-tages, and comparison between groups was analyzed by the chi-square test. Bonferroni correction was used for pairwise comparison. The inspection level was 0.016 7 in the multiple comparison. Results:(1) Bile bacteria in different preoperative biliary drainage methods: of 317 patients, 116 cases were positive for bacterial culture, including 168 strains of 43 bacterial types. There were 46 strains from 36 patients without preoperative biliary drainage, 49 strains from 39 patients with preoperative PTCD and 73 strains from 41 patients with preoperative ERBD. ① The positive rate of bacteria for 317 patients was 36.59%(116/317). The positive rates of bacteria for patients without preoperative biliary drainage, patients with preoperative PTCD and patients with preoperative ERBD were 22.78%(36/158), 33.91%(39/115) and 93.18%(41/44). There was a significant difference in the positive rate of bacteria among the three groups ( χ2=74.066, P<0.05). There was no significant difference between patients with preoperative PTCD and patients without preoperative biliary drainage ( χ2=4.137, P>0.016 7), but there were significant differences between patients with pre-operative ERBD and patients without preoperative biliary drainage or patients with preoperative PTCD ( χ2=72.305, 44.718, P<0.016 7). ② The overall multiple bacterial rate was 36.21%(42/116). The multiple bacterial rates for patients without preoperative biliary drainage, patients with preoperative PTCD and patients with preoperative ERBD were 19.44%(7/36), 23.08%(9/39) and 63.41%(26/41). There was a significant difference in multiple bacterial rate among the three groups ( χ2=20.431, P<0.05). There was no significant difference between patients with PTCD and patients without preoperative biliary drainage ( χ2=0.147, P>0.016 7), but there were significant differences between patients with preoperative ERBD and patients without preoperative biliary drainage or patients with preoperative PTCD ( χ2=15.133, 13.215, P<0.016 7). ③ The overall prevalence rate of multi-drug resistant organism was 30.95%(52/168). The prevalence rates of multi-drug resistant organism for patients without preoperative biliary drainage, patients with preoperative PTCD and patients with preoperative ERBD group were 15.22%(7/46), 26.53%(13/49) and 43.84%(32/73). There was a significant difference in the prevalence rate of multi-drug resistant organism among the three groups ( χ2=11.447, P<0.05). There was no significant difference between patients with PTCD and patients without preoperative biliary drainage ( χ2=1.827, P>0.016 7). There was a significant difference between patients with preoperative ERBD and patients without preoperative biliary drainage ( χ2=10.497, P<0.016 7), but there was no significant difference between patients with preoperative ERBD and patients with preoperative PTCD ( χ2=3.772, P>0.016 7). (2) Clinicopatho-logical characteristics of patients with positive bile bacteria: age, the history of abdominal surgery, degree of jaundice and location of biliary obstruction of patients were not related to the positive rate of bacterial culture ( χ2=4.865, 1.423, 4.922, 0.030, P>0.05). (3) Drug resistance of bile bacteria in different methods of preoperative biliary drainage: for patients without preoperative biliary drainage, the drug resistance rate of Gram-positive bacteria to nitrofurantoin, linezolid and tigecycline was 0, and the drug resistance rate of Gram-negative bacteria to piperacillin/tazobactam, gentamicin, tobramycin, amikacin and imipenem was 0. For patients with PTCD, the drug resistance rate of Gram-positive bacteria to linezolid and tigecycline was 0. For patients with ERBD, the drug resistance rate of Gram-positive bacteria to linezolid and tigecycline was 0. In terms of Gram-positive bacteria, linezolid, tigecycline, vancomycin and nitrofurantoin were the top four antibiotics with the lowest resistance rate. In terms of Gram-negative bacteria, imipenem, piperacillin/tazobactam, amikacin and tobramycinn were the top four antibiotics with the lowest resistance rate. Seven strains of fungi showed no resistance to antifungal drugs. Conclusions:Patients with preoperative ERBD are more vulnerable to infectious complications, and more likely to form drug resistant organism and multi-drug resistant organism. For Gram-positive bacteria infection, linezolid, tigecycline and vancomycin can be used for treatment. For Gram-negative bacteria infection, imipenem, piperacillin/trzobactam, amikacin and tobramycin can be used for treatment.
RESUMO
Hilar cholangiocarcinoma is a highly intractable malignancy, and most patients with this disease were diagnosed as a locally advanced stage at their initial presentation. Surgical resection remains as the only curative treatment for hilar cholangiocarcinoma. Hepatic surgeons focus on how to perform radical resection safely and effectively. For locally advanced hilar cholangio-carcinoma, aggressive surgical approach substantially increases the resectability of tumors which were initially regarded as unresectable. Hemihepatectomy or trisectionectomy combined with caudate lobectomy is the standard operation for radical resection of hilar cholangiocarcinoma, vascular resection and lymphadenectomy can be performed selectively. The safety and success of surgical approach is guaranteed by meticulous preoperative management such as preoperative biliary drainage and portal vein embolization, which prevent fatal postoperative complications. Multidisciplinary approach is required for the treatment of hilar cholangiocarcinoma. The combina-tion of aggressive surgical approach and adjuvant therapy remain a promising approach for further improving the resectability of tumors and the survival of patients.
RESUMO
Malignant biliary obstruction (MBO) leads to obstructive jaundice as a result of bile excretion disorder, which may cause complications such as cholangitis, sepsis, hepatic failure and even life-threatening. Biliary drainage is an effective mean to relieve symptoms and improve patients'quality of life. At present, endoscopic retrograde cholangiopancreatography (ERCP) is the first-line palliative treatment for MBO patients without surgical opportunity. In recent years, endoscopic ultrasound-guided biliary drainage (EUS-BD) has been gradually accepted as an alternative to percutaneous transhepatic biliary drainage (PTBD) in MBO with failed ERCP. The available evidence suggests that EUS-BD might even replace ERCP as the first-line procedure in patients with malignant distal biliary obstruction by experienced surgeons. This paper reviews the research progresses of EUS-BD in MBO.
RESUMO
Background: Percutaneous Transhepatic Biliary Drainage (PTBD) is performed either via right or left-ductal approach, on the basis of status of primary confluence, secondary confluence and atrophy of liver parenchyma. Our study compares the complications of two approaches in malignant obstruction. The objectives of this study was to assess and compare complications of PTBD.Methods: This study was a prospective hospital based study performed for a period of 2 years from 2016 to 2018.PTBD was performed either via right in 16 patients or left-ductal approach in 15 patients, on the basis of status of primary biliary confluence and atrophy of liver parenchyma.Results: Both minor and major complications were more common in right-sided approach as compared to left-sided approach with most common major and minor complication being cholangitis (16.12%) and fever (12.9%) respectively.Conclusions: PTBD is an excellent palliative procedure to drain the bile ducts in malignant obstruction. Although complications of PTBD are more common in right sided approach but results are statistically insignificant.
RESUMO
ABSTRACT Background: Percutaneous biliary drainage is a safe procedure. The risk of bleeding complications is acceptable. Frequently, patients with biliary obstructions usually have coagulation disorders thus increasing risk of bleeding. For this reason, patients should always fit the parameters of hemostasis. Aim: To determine whether the percentage of bleeding complications in percutaneous biliary drainage is greater in adults with corrected hemostasis prior to the procedure regarding those who did not require any. Methods : Prospective, observational, transversal, comparative by independent samples (unpaired comparison). Eighty-two patients with percutaneous biliary drainage were included. The average age was 64±16 years (20-92) being 38 male and 44 female. Patients who presented altered hemostasis were corrected and the presence of bleeding complications was evaluated with laboratory and ultrasound. Results: Of 82 patients, 23 needed correction of hemostasis. The approaches performed were: 41 right, 30 left and 11 bilateral. The amount of punctures on average was 3±2. There were 13 (15.8%) bleeding complications, 12 (20%) in uncorrected and only one (4.34%) in the corrected group with no statistical difference. There were no differences in side, number of punctures and type of drainage, but number of passes and the size of drainage on the right side were different. There was no related mortality. Conclusion: Bleeding complications in patients requiring hemostasis correction for a percutaneous biliary drainage was not greater than in those who did not require any.
RESUMO Racional: A drenagem biliar percutânea é procedimento seguro. O risco de complicações hemorrágicas é aceitável. Frequentemente, os pacientes com obstruções biliares apresentam distúrbios de coagulação, aumentando o risco de sangramento. Por esse motivo, eles devem sempre ser adequados aos parâmetros da hemostasia. Objetivo: Determinar se a porcentagem de complicações hemorrágicas na drenagem biliar percutânea é maior em adultos com hemostasia corrigida antes do procedimento em relação àqueles que necessitaram nenhuma. Métodos: Estudo prospectivo, observacional, transversal, comparativo por amostras independentes (comparação não pareada). Oitenta e dois pacientes foram submetidos à drenagem biliar percutânea. A idade média foi de 64±16 anos (20-92), 38 eram homens e 44 mulheres. Os pacientes que apresentaram hemostasia alterada foram corrigidos, e a presença de complicações hemorrágicas foi avaliada com exames laboratoriais e ultrassonográficos. Resultados: Dos 82 pacientes, 23 necessitaram de correção da hemostasia. O acesso à direita foi em 41 casos, 30 à esquerda e 11 bilaterais. A quantidade de punções em média foi de 3±2. Houve 13 (15,8%) complicações hemorrágicas, 12 (20%) no grupo não corrigido e apenas uma (4,34%) no corrigido sem diferença estatística. Não houve diferenças no lado, no número de perfurações e no tipo de drenagem, mas o número de passagens e o tamanho da drenagem no lado direito foram diferentes. Não houve mortalidade. Conclusão: As complicações hemorrágicas em pacientes que necessitam de correção da hemostasia antes da drenagem biliar percutânea não são maiores do que naqueles que não a requerem.

Objective To observe the efficacy of percutaneous transhepatic biliary drainage (PTBD) combined with transarterial chemoembolization (TACE) in treatment of malignant obstructive jaundice, and to evaluate its application value in clinic. Methods A total of 82 patients with malignant obstructive jaundice who received PTBD from January 2017 to January 2019 in Taiyuan Central Hospital were collected. The patients were divided into the experimental group who received TACE (41 cases) and the control group who could not receive TACE (41 cases) after PTBD. Clinical symptoms, liver function, tumor markers, drainage tube patency rate and survival time of the two groups were compared before and after the treatment. T-test and chi-square test were used for statistical analysis, and Kaplan-Meier method was used for survival analysis. Results A total of 93 drainage tubes were placed in 82 patients, and 109 TACE treatments were performed in the experimental group. PTBD and TACE both had successful results. After PTBD, 72 patients felt jaundiceand obvious alleviation of other clinical symptoms. There were no serious complications after PTBD and TACE. Postoperative follow-up results showed that compared with the total bilirubin (TBIL) [(269±113)μmol/L], the direct bilirubin (DBIL) [(159 ±74) μmol/L], alanine transaminase (ALT) [(118 ±40) U/L] and aspartate aminotransferase (AST) [(111±55) U/L] before the operation, the TBIL [(46±11)μmol/L], DBIL [(28±10)μmol/L], ALT [(35±12) U/L] and AST [(33±12) U/L] in the experimental group were decreased significantly 3 months after the operation, and the differences were statistically significant (all P<0.05). TBIL [(48±9)μmol/L], DBIL [(25±10) μmol/L], ALT [(32±9) U/L] and AST [(30±12) U/L] in the control group were decreased significantly compared with TBIL [(291±114)μmol/L, DBIL [(171±66)μmol/L], ALT [(129±54) U/L] and AST [(114±43) U/L] before the operation, and the differences were statistically significant (all P< 0.05). There was no significant difference in liver function between the two groups before the operation and 3 months after the operation (both P>0.05). The level of carbohydrate antigen-199 in the experimental group at 6 months after PTBD was lower than that in the control group [(426 ±136) U/ml vs. (569 ±204) U/ml; t = 19.457, P < 0.05]. There were statistical differences in the patency rate of the both groups at 6, 9 and 12 months after PTBD (all P< 0.05). The median survival time in the experimental group was longer than that in the control group (310.4 d vs. 234.5 d; χ2= 12.678, P< 0.05). Conclusion The effect of PTBD in patients with malignant obstructive jaundice is obvious. The combination with TACE after PTBD can prolong the survival of patients and it is worthy of clinical application.

RESUMO
Objective To observe the clinical effect of using Chaihu Qingdan decoction in the treatment of acute severe cholangitis (ACST) after endoscopic biliary drainage (ENBD). Methods One hundred and thirty two patients with ACST with ENBD admitted to Dongli District Hospital of Tianjin from October 2016 to October 2017, they were divided into a control group (42 cases) and a Chaihu Qingdan decoction group (90 cases) according to whether the patients accepted traditional Chinese medicine (TCM) treatment or not. The patients in the control group and the Chaihu Qingdan decoction group (combined group) were all treated with ENBD; the control group received routine anti-inflammatory treatment; the combined group, on the basis of conventional anti-inflammatory treatment, additionally was treated with Chaihu Qingdan decoction (composition: bupleurum chinense 18 g, capillary artemisia 30 g, astragalus root 20 g, radix paeoniae rubra 20 g, radix scutellariae 15 g, radix scutellariae 15 g, polygoni 15 g, rhododendron bungeanum 30 g, red cane 30 g, forsythia 20 g, bergamot15 g), 1 dose per day, 2 times daily, 10 days constituting a therapeutic course. After treatment, the difference of operation success rate, abdominal pain relief time, postoperative body temperature return to normal time, liver function, the incidence of postoperative complications, hospitalization time were observed. Results The success rate of operation in the combined group was higher than that in the control group [97.78% (88/90) vs. 95.24% (40/42)], but the difference was not statistically significant (P > 0.05); the relief time of abdominal pain in the combined group was significantly shorter than that of the control group (days: 6.1±1.1 vs. 7.4±1.5, P < 0.05), and the postoperative body temperature return to normal time in combined group was obviously shorter than that in the control group (days: 2.1±0.4 vs. 2.2±0.6, P > 0.05). With the prolongation of treatment, the levels of body temperature, white blood cell count (WBC), direct bilirubin (DBil), alanine aminotransferase (ALT) and aspartate transaminase (AST) were decreased gradually in both groups, reaching the lowest levels on 10 days after treatment, and the above indexes in the combined group were significantly lower than those in the control group [body temperature (℃):36.44±0.24 vs. 37.04±0.39, WBC (×109/L): 7.03±1.23 vs. 8.92±2.11, DBil (μmol/L): 12.03±4.53 vs. 20.32±6.12, ALT (U/L): 31.23±4.23 vs. 68.92±6.19, AST (U/L): 34.03±11.23 vs. 78.92±22.19, all P < 0.05]; after treatment, the total bilirubin (TBil) in both groups was lower than that before treatment, and the combined group was significantly lower than that in the control group after treatment (μmol/L: 61.59±11.64 vs. 82.33±12.05, P < 0.05); the incidence of complications in the combined group was significantly lower than that in the control group [3.33% (3/90) vs. 28.57% (12/42), P < 0.05], and the hospitalization time was shorter in the combined group than that in the control group (days:11.4±2.2 vs. 18.2±3.4, P < 0.05). Conclusion For patients with severe biliary tract inflammation, ENBD combined with Chaihu Qingdan decoction can reduce postoperative complications, reduce abdominal pain relief time, and accelerate liver function recovery.
RESUMO
Objective To evaluate the feasibility and safety of guidewire guidance method in percutaneous transhepatic biliary drainage (PTBD). Methods A total of 174 consecutive patients with biliary diseases who underwent PTBD in Heilongjiang Provincial Hospital from January 2011 to December 2017 were enrolled in this retrospective study. There were 85 patients undergoing conventional PTBD ( the conventional group), and 89 wire-guided PTBD (the wire-guided group). In the wire-guided group, the contrast media was not injected immediately after puncture, on the contrary, the needle coat was inserted deeply along the bile duct thereafter, then the bile was extracted to reduce the pressure of bile duct, at last the contrast media was infused. The drainage success rate and incidence of cholangitis related with PTBD were compared between the two groups. Results The incidence of PTBD-related cholangitis of the wire-guided group was significantly lower compared with the conventional group [ 10. 1％ ( 9/89 ) VS 21. 2％( 18/85) ,χ2=5. 270, P=0. 022] , although the drainage success rate was not significantly different between the two groups [ 94. 4％ ( 84/89) VS 97. 6％ ( 83/85) ,χ2=1. 200, P=0. 273] . Conclusion Wire-guided PTBD may yield a similar success rate, but can reduce the incidence of cholangitis compared with conventional PTBD.

RESUMO
Objective@#To investigate the effects of preoperative percutaneous transhepatic biliary drainage on surgical treatment of type Ⅲ and Ⅳ hilar cholangiocarcinoma.@*Methods@#Clinical data of 72 patients with hilar cholangiocarcinoma of the Bismuth-Corlette type Ⅲ and Ⅳ treated at Department of General Surgery,First Affiliated Hospital of Bengbu Medical College from January 2010 to December 2017 were analyzed retrospectively.Patients were divided into two groups based on whether PTBD was performed:a drained group and an undrained group.In the drained group,there were 31 patients,20 males and 11 females,aged (59.9±9.7)years (range: 39-73 years).Among them,14 patients underwent hepatectomy with half or more than half of the liver removed (extended hepatectomy)and 17 patients underwent non-anatomical hepatectomy in the hilar region (limited hepatectomy).In the undrained group,there were 41 patients, 26 males and 15 females, aged (60.8±7.8)years(range: 45-75 years).Among them, 17 patients underwent hepatectomy with half or more than half of the liver removed (extended hepatectomy)and 24 patients underwent non-anatomical hepatectomy in the hilar region (limited hepatectomy).Percutaneous transhepatic biliary drainage(PTBD)was used in the drained group.Under the guidance of ultrasound,one or more hepatobiliary ducts could be sufficiently drained,which had good effect and was not restricted by the obstruction location of hilar cholangiocarcinoma.The analysis of the measurement data was performed using t test,and the analysis of the count data was performed using χ2 test,and the survival curve was plotted using Kaplan-meier method.@*Results@#In total, 72 jaundiced patients with hilar cholangiocarcinoma underwent surgical treatment: 31 had PTBD prior to operation while 41 did not had PTBD.There were significant differences in ALT((93.2±21.4)U/L vs.(207.4±65.1)U/L),AST((87.6±18.1)U/L vs.(188.9±56.6)U/L)and total bilirubin((68.8±12.6)μmol/L vs.(227.5±87.7)μmol/L)between the patients after treatment and those before treatment(t=10.958, P=0.000; t=10.845, P=0.000; t=10.386, P=0.000).Compared with those in the undrained group, the operation time was shorter, the amount of intraoperative bleeding and the incidence of complications were lower in the drained group(t=-2.840, P=0.006; t=-3.698, P=0.000; χ2=4.108, P=0.043).There were no perioperative death cases in drained group and 2 perioperative death cases in undrained group.There was no significant difference in R0 resection rate between the two groups(χ2=0.778,P=0.378).The 1-,3-,5-year survival rate of patients in the drained group and the undrained group was 72.7%,34.2%, 13.7% and 72.8%, 31.5%, 11.8%, respectively.The difference was not statistically significant(all P>0.05).@*Conclusions@#The preoperative percutaneous transhepatic biliary drainage in patients with hilar cholangiocarcinoma of Bismuth-Corlette type Ⅲ and Ⅳ could effectively shorten operative time, reduce amount of intraoperative bleeding and incidence of postoperative complications,but have no significant effect on the R0 resection rate and survival rate.
RESUMO
Although endoscopic retrograde cholangiopancreatography (ERCP) is the first-line treatment for benign biliary diseases, this procedure is technically difficult in some conditions such as a surgically altered anatomy and gastric outlet obstruction. After a failed ERCP, a surgical or a percutaneous approach is selected as a rescue procedure; however, various endoscopic ultrasound (EUS)-guided interventions are increasingly utilized in pancreatobiliary diseases, including EUS-guided rendezvous for failed biliary cannulation, EUS-guided antegrade treatment for stone management, and EUS-guided hepaticogastrostomy for anastomotic strictures in patients with a surgically altered anatomy. There are some technical hurdles in EUS-guided interventions for benign biliary diseases owing to the difficulty in puncturing a relatively small bile duct and in subsequent guidewire manipulation, as well as the lack of dedicated devices. A recent major advancement in this field is the introduction of a 2-step approach, in which EUS-guided drainage is placed in the first session and antegrade treatment is performed in subsequent sessions. This approach allows the use of various techniques such as mechanical lithotripsy and cholangioscopy without a risk of bile leak. In summary, EUS-guided interventions are among the treatment options for benign biliary diseases; however, standardization of the procedure and development of a treatment algorithm are needed.
