RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
Objective To systematically review the effectiveness and safety of percutaneous transhepatic biliary drainage (PTBD) versus endoscopic biliary drainage (EBD) for preoperative biliary drainage in patients with Klatskin Tumors.Methods The Pubmed,Embase,Web of Science,CNKI,VIP and WanFang Data from January 1998 to December 2017 were searched for published studies which compared endoscopic biliary drainage (EBD) with percutaneous transhepatic biliary drainage (PTBD) for preoperative biliary drainage.A Meta-analysis was then performed using the Revman 5.3 software.Results Seven cohort studies were included.There were 366 patients in the PTBD group,and 400 patients in the EBD groups.When compared with EBD,PTBD was associated with a lower risk of cholangitis (OR=0.31,95％ CI 0.20～0.48,P＜0.05),a lower risk of pancreatitis (OR=0.11,95％ CI 0.04 ～ 0.34,P＜0.05),and a lower risk of overall complications (OR=0.48,95％ CI 0.30 ～ 0.77,P=0.002).The rate of conversion from one procedure to the other was significantly lower in the PTBD group than the EBD group.The initial technical success rate and postoperative morbidity and mortality rates were similar in the 2 groups.Conclusion In patients with Klatskin tumors who require PBD,PTBD is a better initial biliary drainage method with lower incidences of procedure-related cholangitis,pancreatitis overall complications and conversion to other drainage procedures.
RESUMEN
Preoperative biliary drainage (PBD) is an important part of preoperative management of patients with hilar cholangiocarcinoma which could reduce serum total bilirubin,remove jaundice,improve liver function,and reduce the mortality and morbidity.Although PBD is widely used in biliary surgery now,there are still several controversial issues in clinical applications about the indication of PBD,the best way of PBD,implantation metastasis of PBD and so on.With the development of medical image and surgical technology,we had a better understanding of PBD now.This review summarizes the recent scenario and current advancement about the above-mentioned controversy.
RESUMEN
Objective To determine the impact and the risk factors of different methods of preoperative biliary drainage (PBD) for malignant obstruction jaundice (MOJ) on overall survival (OS).Methods Databases including the PubMed,Medline,Web of Knowledge,and other databases were searched up to 30th April,2018 for clinical studies which compared the OS rates between percutaneous transhepatic biliary drainage (PTBD) and endoscopic biliary drainage (EBD) for MOJ.Hazard ratio (HR) and Odds Ratio (OR) with 95％ confidence interval (CI) were performed using the Review Manager 5.3 software to synthesize the results.Results Nine studies were enrolled in this meta-analysis,which included 818 patients in the PTBD group and 1253 patients in the EBD group.EBD was shown to be superior to PTBD in OS (HR=0.63,95％ CI:0.51～0.77,P＜0.05).Risk factors analysis showed that patients in the EBD group had a higher rate of early tumor stage (P＜0.05) and a lower rate of lymphatic metastasis (P＜0.05).When compared with the PTBD group,the EBD group had a lower rate of intraoperative bleeding (P＜0.05),and a higher rate of adjuvant therapy (P＜0.05).Conclusion In PBD for patients with resectable MOJ,there was insufficient evidence to support EBD to be superior to PTBD in OS.
RESUMEN
Objective:To investigate the influence of preoperative biliary drainage (PBD) on morbidity of severely obstructive jaundice patients after pancreaticoduodenectomy (PD).Methods:A total of 98 severely obstructive jaundice(Serum total bilirubin＞300 μ mool/L) patients underwent PD between February 2010 and October 2015 were enrolled in the study.The patients were divided into two groups based on undergoing PBD or not.The no-PBD group comprised 52 patients and the PBD group comprised another 46 patients.Perioperatives parameters,including operative time,intraoperative blood loss,postoperative mortality and morbidity and postoperative hospital stay were compared between the two groups.Results:The demographics,preoperative examinations and pathological results were similar between the two groups (P＞0.05).Operative time of the no-PBD group was statistically longer than the PBD group (379.44 ± 88.57min vs 346.98 ± 57.17 min,P＜0.05).Besides,intraoperative blood loss of the no-PBD group were much more than the PBD group (365.00 ± 187.07mL vs 297.83 ± 139.57 mL,P＜0.05).There was no statistical difference of mortality rate between the no-PBD group and the PBD group(3.85％ vs 2.17％,P＞0.05).The overall morbidity rate of the 2 groups were similar (53.85％ vs 43.48％,P＞0.05),but the pancreatic fistula rate of no-PBD group was significantly higher than the PBD group (30.77％ vs 13.04％,P＜0.05).Conclusion:PBD could reduce operative time,intraoperative blood loss and pancreatic fistula rate after PD.Meanwhile,the mortality and overall morbidity rates were similar between the two groups.PBD should be considered for severely obstructive jaundice patients.
RESUMEN
Palliation of jaundice improves the general health of the patient and, therefore, surgical outcomes. Because of the complexity and location of strictures, especially proximally, drainage has been accompanied by increased morbidity due to sepsis. Another concern is the provocation of an inflammatory and fibrotic reaction around the area of stent placement. Preoperative biliary drainage with self-expanding metallic stent (SEMS) insertion can be achieved via a percutaneous method or through endoscopic retrograde cholangiopancreatography. A recently published multicenter randomized Dutch study has shown increased morbidity with preoperative biliary drainage. A Cochrane meta-analysis has also shown a significantly increased complication rate with preoperative drainage. However, few of these studies have used a SEMS, which allows better biliary drainage. No randomized controlled trials have compared preoperative deployment of SEMS versus conventional plastic stents. The outcomes of biliary drainage also depend on the location of the obstruction, namely the difficulty with proximal compared to distal strictures. Pathophysiologically, palliation of jaundice will benefit all patients awaiting surgery. However, preoperative drainage often results in increased morbidity because of procedure-related sepsis. The use of SEMS may change the outcome of preoperative biliary drainage dramatically.

BACKGROUND/AIMS: Controversy remains over the optimal approach to preoperative biliary drainage in patients with resectable perihilar cholangiocarcinoma. We compared the clinical outcomes of endoscopic biliary drainage (EBD) with those of percutaneous transhepatic biliary drainage (PTBD) in patients undergoing preoperative biliary drainage for perihilar cholangiocarcinoma. METHODS: A total of 106 consecutive patients who underwent biliary drainage before surgical treatment were divided into two groups: the PTBD group (n=62) and the EBD group (n=44). RESULTS: Successful drainage on the first attempt was achieved in 36 of 62 patients (58.1%) with PTBD, and in 25 of 44 patients (56.8%) with EBD. There were no significant differences in predrainage patient demographics and decompression periods between the two groups. Procedure-related complications, especially cholangitis and pancreatitis, were significantly more frequent in the EBD group than the PTBD group (PTBD vs EBD: 22.6% vs 54.5%, p<0.001). Two patients (3.8%) in the PTBD group experienced catheter tract implantation metastasis after curative resection during the follow-up period. CONCLUSIONS: EBD was associated with a higher risk of procedure-related complications than PTBD. These complications were managed properly without severe morbidity; however, in the PTBD group, there were two cases of cancer dissemination along the catheter tract.

Objective To investigate the effects of preoperative biliary drainage ( PBD ) on the morbidity and mortality of pancreaticoduodenectomy in patients with malignant obstructive jaundice in the lower bile duct. Methods Clinical data of 74 cases undergoing pancreaticoduodenectomy from Jan. 2000 to Dec. 2005 with preoperative total bilirubin level over 85 μmol/L were collected and retrospectively analyzed. Comparison was performed between patients receiving PBD and those not. Before surgery. The parameters sincluding perioperative situation, in-hospital death rate, post-operative complications and were calculated to evaluate the influence of pre-operative biliary drainage on the outcomes. Univariate analysis and Logistic analysis were used to identify the risk factors for post-operative complications. Results Forty (40/74) cases received PTCD procedure. The total bilirubin was significantly reduced from (338. 10±88. 38 )μwnol/L to ( 228. 50±82.24) μ,mol/L in PTCD population and was significantly lower than ( 328. 60±93. 02) μmol/L of the non-PTCD group. There was no significance between the two groups in terms of total complications and individual complication Logistic regression analysis showed that preoperative TB over 340 μmol/L and blood loss over 600 ml were important risk factors for post-operative complications. Conclusion High pre-operative total bilirubin over 340 μmol/L increases the risk of post-operative complications in the patients with malignant jaundice. Preoperative biliary drainage is useful to reduce the total bilirubin and improve the hepatic function of the patients. Prolonged pre-operative biliary drainage could be considered in the patients with high preoperative bilirubin,poor nutritional condition and impaired coagulation to enhance the tolerance of surgery.
RESUMEN
Background/Aim. There are theoretic arguments in favor and against biliary drainage before the pancreatoduodenectomy. Most of the studies failed to show any beneficial effect of this aproach whereas others even reported an increased postoperative morbidity related with biliary drainage. Therefore, the role of preoperative biliary drainage remains controversial. So, we decided to analyze our own results in a series of patients undergoing pancreatoduodenectomy in order to determine the association between preoperative biliary drainage and postoperative outcome. Patients and Methods. We analyzed 109 patients undergoing pancreatoduodenectomy between January 1990 and May 2003. Patients were classified in 3 groups: Group 1 (n = 64) patients without preoperative biliary drainage, Group 2 (n = 27) patients who underwent preoperative biliary drainage with sphincterotomy and stent placement, and Group 3 (n = 18) only sphincterotomy. Demographic characteristics, surgical risk, comorbility, type of surgery, pathology and biochemical parameters were analyzed. We also, stratified patients with and without cholestasis (total bilirubin > 3mg/dL), and divided patients in two groups: with biliary drainage and without biliary drainage. Surgical and medical complications, the frequency of patients with at least one complication (global morbidity) and mortality were compared between groups. KruskaTWallis, Mann-Whitney U, x2 and Fisher tests were used for the analysis of categorical and dimensional variables. Results. The most frequent postoperative diagnoses were biliopancreatic tumors. Global postoperative morbidity and mortality were 40% (n = 44) and 10% (n = 11), respectively. The frequency of surgery and medical complications were no significantly different among the 3 groups. However, when only patients with cholestasis were analyzed (n = 65), there was a lower frequency of surgical complications and global postoperative morbidity in patients with preoperative biliary drainage (p = 0.02, OR 0.14, CI 95% 0.04-0.50 and p < 0.001, OR 0.18, CI 95% 0.05-0.65, respectively). There were not significant differences in the frequency of medical complications (p = 0.09) and mortality. Conclusions. Preoperative biliary drainage should not be considered as a routine procedure in candidates undergoing pancreatoduodenectomy; however, this maneuver decreased approximately seven times the risk of postoperative global morbidity in patients with cholestasis, mainly by reducing surgical complications reduction.
Antecedentes/Objetivo. Existen argumentos teóricos a favor y en contra para realizar un drenaje biliar previo a pancreatoduodenectomía. En la mayoría de los estudios no se ha podido establecer un efecto benéfico de esta conducta e incluso se ha informado un incremento en la morbilidad postoperatoria relacionada con el drenaje. Por lo tanto, la evidencia acerca de la utilidad de este procedimiento sigue siendo controversial, probablemente por la heterogeneidad en los estudios publicados. Con objeto de establecer una conducta basada en nuestra experiencia institucional analizamos una serie de pacientes sometidos a pancreatoduodenectomía para determinar la asociación entre el drenaje biliar preoperatorio y la evolución posquirúrgica. Pacientes y métodos. Se analizaron 109 pacientes consecutivos a quienes se les realizó pancreatoduodenectomía de enero de 1990 a mayo del 2003. Se dividieron en tres grupos: Grupo 1 (n = 64) sin drenaje biliar preoperatorio, Grupo 2 (n = 27) con esfinterotomía y colocación de endoprótesis y Grupo 3 (n = 18) sólo esfinterotomía. En todos los casos se analizaron las características demográficas, riesgo quirúrgico, comorbilidad, tipo de cirugía, estudio histopatológico y parámetros bioquímicos. Se estratificaron los pacientes de acuerdo a la presencia de colestasis, definida por bilirrubinas totales > 3 mg/dL y se agruparon en dos categorías: sin drenaje y con drenaje biliar. Se compararon las complicaciones postoperatorias quirúrgicas y médicas, así como el número de pacientes con al menos una complicación (morbilidad global) y la mortalidad. El análisis estadístico para la comparación entre los tres grupos se realizó con x2 y prueba exacta de Fisher para las variables categóricas y Kruskal-Wallis o U de Mann-Whitney para las variables dimensionales. Resultados. Los diagnósticos postoperatorios más frecuentes fueron tumores de la encrucijada biliopancreática. La morbilidad postoperatoria global fue de 40% (n = 44) y la mortalidad de 10% (n = 11). No hubo diferencias significativas en la frecuencia de complicaciones quirúrgicas y médicas entre los tres grupos. Sin embargo, cuando se analizaron sólo pacientes con colestasis (n = 65), la frecuencia de complicaciones quirúrgicas y morbilidad global postoperatoria fue significativamente menor en los grupos con drenaje biliar preoperatorio (p = 0.02, RM 0.14, IC 95% 0.04-0.50 y p < 0.001, RM 0.18, IC 95% 0.05-0.65, respectivamente). No se presentaron diferencias significativas en relación con la frecuencia de complicaciones médicas (p = 0.09) y mortalidad. Conclusiones. El drenaje biliar preoperatorio no debe ser considerado un procedimiento de rutina en candidatos a pancreatoduodenectomia; sin embargo, en los pacientes con colestasis, esta maniobra disminuye casi siete veces el riesgo de morbilidad global postoperatoria, predominantemente al reducir las complicaciones quirúrgicas.

PURPOSE: A preoperative biliary drainage procedure (endoscopic nasogastric biliary drainage, ENBD; endoscopic retrograde biliary drainage, ERBD; or percutaneous transhepatic biliary drainage, PTBD) is infrequently performed in periampullary cancer patients with obstructive jaundice. Among these different biliary drainage procedures, a safer and more informative procedure should be performed in the indicated cases. However, no comparative study has been done between the two biliary drainage methods (endoscopic vs. percutaneous). The aim of this study is to compare the clinical outcome of these two biliary drainage methods in periampullary cancer and to suggest guidelines for selecting the appropriate preoperative biliary drainage procedure. METHODS: Between January 1996 and June 2002, 25 patients underwent pancreaticoduodenectomy (Whipples' operation or pylorus preserving pancreaticoduodenectomy) after ENBD/ERBD (Group A) due to periampullary cancer. Twenty- five patients who ubderwent PTBD preoperatively were matched with Group A, according to age group, sex, diagnosis, and type of operation during the same period (Group B). RESULTS: There were no differences in operative time, intraoperative/postoperative transfusion, total/postoperative length of hospital stay, incidence of postoperative complication, TNM staging, or perineural/endovascular/endolymphatic invasion. However, the thickness of CBD wall (Group A: Group B=1.78+/-0.55 mm : 1.14+/-0.37 mm, P Group B, P<0.001) were significantly different between the two groups. CONCLUSION: Although a significant difference of clinical outcome between the two preoperative biliary drainage methods could not be identified in this study, the inflammation of operative field resulting from ENBD/ERBD is expected to cause surgical difficulties and ultimately affect postoperative complications.

BACKGROUNDING AND AIM: Recent reports have suggested that preoperative biliary drainage increases the perioperative morbidity and mortality rates of pancreaticoduodenectomy. We reviewed retrospectively 150 patients who underwent pancreaticoduodenectomy to examine the relationship between preoperative biliarydrainage and the morbidity and mortality associated with pancreaticoduodenectomy. METHODS: Peri-operative morbidity and mortality were evaluated in 150 consecutive patients who underwent pancreaticoduodenectomy at Pusan National University Hospital for 10 years. Univariate and multivariate logistic regression analysis were done to evaluate the relationship between preoperative biliary decompression and the following end points: any complication, any major complication, infectious complications, intraabdominal abscess, pancreaticojejunal anastomotic leak, wound infection, and postoperative death. RESULTS: Preoperative prosthetic biliary drainage was performed in 86 patients (57.3%) (stent group), 17 patients (11.3%) underwent surgical biliary bypass performed during prereferral laparotomy, and the remaining 47 patients(31.3%) (no-stent group) did not undergo any form of preoperative biliary decompression. The overall surgical death rate was 1.3% (two patients); the number of deaths was too small for multivariate analysis. By multivariate logistic regression, no differences were found between the stent and no-stent groups in the incidence of all complications, major complications, infectious complications, intraabdominal abscess, or pancreaticojejunal anastomotic leak. Wound infections were more common in the stent group than the no-stent group. CONCLUSIONS: Preoperative biliary decompression increases the risk for postoperative wound infections after pancreaticoduodenectomy. However, there was no increase in the risk of major postoperative complications or death associated with preoperative stent placement. Patients with extrahepatic biliary obstruction do not necessarily require immediate laparotomy to undergo pancreaticoduodenectomy with acceptable morbidity and mortality rates; such patients can be treated by endoscopic biliary drainage without concern for increased major complications and death associated with subsequent pancreaticoduodenectomy.
