The effect of pre-operative biliary drainage in resectable periampullary lesions: a systematic review and meta-analysis.

The effect of a pre-operative biliary stent on complications after pancreaticoduodenectomy (PD) remains controversial. We conducted a meta-analysis according to the preferred reporting items for systematic reviews and meta-analyses guidelines, and PubMed, Web of Science Knowledge, and Ovid's databases were searched by the end of February 2023. 35 retrospective studies and 2 randomized controlled trials with a total of 12641 patients were included. The overall complication rate of the pre-operative biliary drainage (PBD) group was significantly higher than the no-PBD group (odds ratio [OR] 1.46, 95% confidence interval [CI] 1.22-1.74; p < 0.0001), the incidence of post-operative delayed gastric emptying was increased in patients with PBD compared those with early surgery (OR 1.21, 95% CI: 1.02-1.43; p = 0.03), and there was a significant increase in post-operative wound infections in patients receiving PBD with an OR of 2.2 (95% CI: 1.76-2.76; p < 0.00001). PBD has no beneficial effect on post-operative outcomes. The increase in post-operative overall complications and wound infections urges the exact indications for PBD and against routine pre-operative biliary decompression, especially for patients with total bilirubin < 250 umol/L waiting for PD.

Effects of preoperative biliary drainage on the outcomes of surgical treatment in cholangiocarcinoma: A propensity score matching analysis

BackgroundHyperbilirubinemia is known to increase morbidity and mortality in patients undergoing liver resection for cholangiocarcinoma (CCA). Preoperative biliary drainage (PBD) in patients who have no acute cholangitis or require portal vein embolization is still debatable. The goal of this study is to investigate how PBD affects the surgical results after liver resection. MethodsBetween October 2013 and December 2020, CCA patients presenting with obstructive jaundice who underwent liver resection were retrospectively reviewed. The pre-operative, peri-operative and post-operative characteristics were extracted. To compare the outcomes of the PBD and direct surgery groups, propensity score matching analysis (PSM) and multivariable risk regression analysis were used to analyze. ResultsA total of 355 patients were enrolled, with 99 of them undergoing PBD. At diagnosis, those with PBD showed significantly greater bilirubin levels than those without (20.7 vs 9.6 ​mg/dL, p ​< ​0.001). However, after drainage, the bilirubin level in the PBD group was lower than the direct surgery group (5.5 vs 9.6 ​mg/dL, p ​< ​0.001). Overall postoperative morbidity and mortality were unaffected by PBD in full patient cohort. However, after PSM, PBD was associated with decreased major post-hepatectomy liver failure (PHLF) and 90-day mortality rate, (20.3% vs 39.24%, p ​= ​0.014 and 3.8% vs 22.8%, p ​= ​0.001, respectively). At multivariable analysis of PSM patient cohort, PBD was associated with decreased major post-operative complication (RR 0.64, 95%CI 0.419–0.986), PHLF (RR 0.40, 95%CI 0.227–0.705) and 90-day mortality (RR 0.21, 95%CI 0.086–0.629). ConclusionPBD was associated with decreased post-hepatectomy liver failure and postoperative mortality after liver resection in jaundiced CCA patients.

The effect of preoperative biliary drainage on postoperative complications of pancreaticoduodenectomy: a triple center retrospective study

BackgroundBiliary obstruction which is a major complication of pancreas and periampullary tumors could result in cholangitis, coagulopathies, gastrointestinal symptoms, and impaired wound healing. Pancreaticoduodenectomy (PD) is still the standard approach for pancreas resection and imposes high risk of morbidity and mortality to patients. To reduce the high risk of PD and address the biliary obstruction, the use of preoperative biliary stenting was increased. However, available literature doubts its efficiency.MethodsA total of 147 patients who underwent PD between September 2012, and February 2022, at three medical centers were identified. Patients were grouped based on biliary stent placement. Non-jaundiced patients with and without preoperative biliary drainage (PBD) were compared.ResultsThe incidence of overall complications (34.2% versus 45.8%) and mortality (17.8% versus 24.3%) did not differ in the PBD group compared to the no PBD group. There was no difference in complications and mortality in non-jaundiced patients with and without PBD. Patients with drainage duration of > 30 days experienced more overall complications compared to patients with less than 30 days drainage duration (12 (50.0%) and three (15.8%) patients, respectively, p-value = 0.019).ConclusionsPBD does not significantly increase the post-operative burden on patients who undergo PD. However, we cannot overlook the financial burden that PBD places on the patient and the healthcare system, as well as the difficulties related to endoscopic retrograde cholangiopancreatography (ERCP). Therefore, biliary stenting should not be routinely practiced in the absence of a valid indication, such as severe jaundice, pruritus, cholangitis, delayed surgery for neoadjuvant treatment, or referral to a tertiary facility.

Impact of preoperative biliary drainage on postoperative complications and prognosis after pancreaticoduodenectomy: A single-center retrospective cohort study.

Obstructive jaundice is common in patients with pancreaticobiliary malignancies. Preoperative biliary drainage (PBD) can alleviate cholestasis; however, no consensus has been reached on the impact of PBD on the incidence of surgery-related complications and patient survival. This study aimed to evaluate the effect among patients treated with PBD. This retrospective study examined the clinical and follow-up prognostic data of 160 patients with pancreaticobiliary malignancies who underwent pancreaticoduodenectomy (PD) at Beijing Friendship Hospital, Capital Medical University, from January 2016 to July 2020. Outcomes were compared between patients who underwent PBD (PBD group) and those who did not (control group). Changes in biochemical indicators were evaluated before and after drainage in the PBD group. Between-group differences in inflammatory indicators after PD were assessed using the Wilcoxon signed-rank test. Postoperative complications were classified according to the Clavien-Dindo classification system. The effects of PBD and biliary drainage efficiency on postoperative complications were evaluated using the chi-square test and binary logistics regression. The Kaplan-Meier analysis was used for between-group comparison of survival analysis. Univariate and multivariate regression analyses were performed to identify prognostic factors of survival. Total 160 patients were enrolled,the mean age of the study sample was 62.75 ± 6.75 years. The distribution of pancreaticobiliary malignancies was as follows: 34 cases of pancreatic head cancer, 61 cases of distal bile duct cancer, 20 cases of duodenal papilla cancer, 39 cases of duodenal ampullary cancer, and 6 cases of malignant intraductal papillary mucinous neoplasm (IPMN). PBD was performed in 90 of the 160 patients, with PBD performed using an endoscopic retrograde cholangiopancreatography (ERCP) approach in 55 patients and with percutaneous transhepatic cholangiography (PTC) used in the remaining 35 cases. The mean duration of drainage in the PBD group was 12.8 ± 8.8 days. The overall rate of complications was 48.05% (37/77) in the control group and 65.55% (59/90) in the PBD group with non-significant difference (χ2 = 3.527, p=0.473). In logsitics regression analysis, PBD was also not a risk factor for postoperative complications OR=1.77, p=0.709). The overall rate of postoperative complications was significantly higher among patients who underwent PBD for >2 weeks (χ2 = 6.102, p=0.013), with the rate of severe complications also being higher for this subgroup of PBD patients (χ2 = 4.673, p=0.03). The overall survival time was 47.9 ± 2.45 months, with survival being slightly lower in the PBD group (43.61 ± 3.26 months) than in the control group (52.24 ± 3.54 months), although this difference was not significant (hazard ratio (HR)=0.65, p=0.104). In patients with malignant biliary obstruction, PBD does not affect the incidence of postoperative complications after pancreaticoduodenectomy nor does it affect patient survival. Prolonged biliary drainage (>2 weeks) may increase the incidence of overall postoperative complications and severe complications.

The Effect of Preoperative Biliary Drainage with or without Pancreatic Stenting on Complications after Pancreatoduodenectomy: A Retrospective Cohort Study.

Background The necessity of preoperative biliary drainage (PBD) prior to pancreaticoduodenectomy (PD) is still controversial. However, in some settings, PBD with endoscopic retrograde cholangiopancreatography (ERCP) procedure is recommended as a preferred management. Meanwhile, pancreatic duct stenting in the drainage procedure is rarely performed for selected indications, and its associated complications after PD remain quite unknown. Methods A retrospective observational longitudinal cohort study was performed on patients who underwent PBD and PD from a prospectively maintained database at the National Cancer Center from March of 2015 to July of 2019. Patients who underwent biliary stenting alone, biliary and pancreatic stenting, were distributed into two study cohort groups, and their records were scrutinized for the incidence of postoperative complications. Results A total of 83 patients who underwent successful PD after biliary drainage were identified. 29 patients underwent nasobiliary drainage (ENBD)/plastic or metal bile duct stenting (BS) and pancreatic duct stenting (PS group), and 54 patients underwent only ENBD/BS, without pancreatic duct stenting (NPS group). No differences were found between the two groups with respect to in-hospital time, overall complication rate, respective rate of serious (grade 3 or higher) complication rate, bile anastomotic leakage, bleeding, abdominal infection, surgical wound infection, organ dysfunction, and pancreatic anastomotic leakage. Postoperative gastrointestinal dysfunction rates differed significantly, which occurred in 3 (5.56%) cases in the NPS group, compared with 6 (20.7%) cases in the PS group (P = 0.06). In the univariate and multivariate regression model analysis, pancreatic duct stenting was correlated with higher rates of gastrointestinal dysfunction [odds ratio (OR) = 4.25, P = 0.0472]. Conclusion Our data suggested that PBD and pancreatic duct stenting prior to pancreatoduodenectomy would increase the risk of postoperative delayed gastric emptying, while the overall incidence of postoperative complications and other complications, such as pancreatic leakage and bile duct leakage, showed no statistical difference.

Effect of Preoperative Biliary Drainage after Pancreaticoduodenectomy

The effect of preoperative biliary stents on outcomes after pancreaticoduodenectomy: A meta-analysis.

Background:Whether biliary drainage should be performed before surgery in jaundiced patients is a topic of debate. Published studies on the effect of preoperative biliary drainage show great discrepancies in their conclusions, and the use of different drainage methods is an important factor. The aim of the present study was to investigate the effect of preoperative biliary stents (PBS) on postoperative outcomes in patients following pancreaticoduodenectomy (PD).Methods:MEDLINE, EMBASE, Science Citation Index Expanded, and the Cochrane database were searched up to October 2019 to identify all published articles related to the topic. A meta-analysis was performed to compare postoperative outcomes in patients with and without PBS. Quality assessment and data extraction from included studies were performed by 2 independent authors. Statistical analysis was performed using RevMan 5.2 software.Results:Twenty-seven studies involving 10,445 patients were included in the analysis. Biliary drainage was performed in 5769 patients (PBS group), and the remaining 4676 patients underwent PD directly (direct surgery [DS] group). Overall mortality, severe complications, abdominal hemorrhage, bile leakage, intra-abdominal abscess, and pancreatic fistula were not significantly different between the PBS and DS groups. However, overall morbidity, delayed gastric emptying, and wound infection were significantly higher in the PBS group compared to the DS group. Subgroup analysis indicated that the adverse effect of PBS on postoperative complications was more evident with increased stent proportion.Conclusions:Preoperative biliary stenting increases overall morbidity, delayed gastric emptying, and wound infection rates in patients following PD. Thus, preoperative biliary drainage via stent placement should be avoided in patients waiting for PD.

Adverse oncologic effects of preoperative biliary drainage on early stage ampulla of Vater cancer

BackgroundThe preoperative biliary drainage (PBD) in ampulla of Vater (AoV) cancer is indiscriminately performed without logical backgrounds. This study was performed to evaluate the effect of PBD on short and long-term outcomes in AoV cancer. Methods313 patients who underwent pancreaticoduodenectomy and were pathologically diagnosed as AoV cancer between January 2000 and December 2014 were reviewed. Results167 patients (53.4%) underwent PBD: Endoscopic drainage was performed in 106 patients (33.9%) and percutaneous drainage in 61 (19.5%). The postoperative complication rate of PBD group was significantly higher than that of upfront surgery group (48.5% vs. 38.4%, p = 0.045). The 5-year disease-free survival rate (5Y-DFSR) was significantly lower in PBD group compared to upfront surgery group (53.8% vs. 74.3%, p < 0.001). Worse 5Y-DFSR of PBD group was more evident in T1/T2 stage (59.2% vs. 84.1%, p < 0.001). In multivariate analysis with T1/T2 staged patients, PBD was independently associated with worse outcome (hazard ratio 2.145 [95% confidence interval, 1.202–3.826], p = 0.010). ConclusionFor T1/T2 AoV cancer, PBD adversely affected the short-term postoperative complication rate as well as the long-term oncologic outcomes. Therefore, especially in patients with T1/T2 AoV cancer, routine practice of PBD should be refrained and be reserved for selected cases such as cholangitis.

Meta-analysis of the efficacy of preoperative biliary drainage in patients undergoing liver resection for perihilar cholangiocarcinoma

PurposeA systematic review was performed to evaluate the effect of preoperative biliary drainage (PBD) on outcomes after liver resection in perihilar cholangiocarcinoma (PHCC) patients. MethodMEDLINE and Web of Science were searched up to March 2019. All studies assessing morbidity, mortality, or recurrence in patients who received PBD and hepatectomy for PHCC were included. Mantel–Haenszel tests with a random-effects model were used for meta-analysis. ResultsSixteen studies involving 2162 patients were included. PBD was associated with higher major morbidity odds ratio [OR] = 1.51; 95 % confidence interval [CI] = 1.14–2.00). Selecting patients for PBD based on simple selection criteria was associated with significantly higher major morbidity (OR = 1.57; 95 % CI = 1.10–2.25). In contrast, selecting patients for PBD according to strict criteria resulted in lower major morbidity compared with patients without PBD (OR = 0.51; 95 % CI = 0.18–1.42). PBD did not influence mortality (OR = 1.06; 95 % CI = 0.70–1.61). Tumor recurrence was significantly higher in the PBD group (OR = 2.07; 95 % CI = 1.38–3.11). To decrease PBD-related complications, the duration between PBD and hepatectomy should be shorter than two weeks. Most reports described PBD on the future liver remnant side. ConclusionsRoutine PBD cannot be recommended but it may be useful in highly selected patients suffering from cholangitis, malnutrition, and long lasting jaundice, for whom an extended hepatectomy is planned. However, However, routine PBD cannot be recommended due to higher morbidity rate after hepatectomy clear patient selection criteria can be defined for PBD in future multicenter randomized controlled studies.

Influence of bile contamination for patients who undergo pancreaticoduodenectomy after biliary drainage.

BACKGROUNDThe influence of bile contamination on the infectious complications of patients undergoing pancreaticoduodenectomy (PD) has not been thoroughly evaluated.AIMTo evaluate the effect of preoperative biliary drainage and bile contamination on the outcomes of patients who undergo PD.METHODSThe database of 4101 patients who underwent PD was reviewed. Preoperative biliary drainage was performed in 1964 patients (47.9%), and bile contamination was confirmed in 606 patients (14.8%).RESULTSThe incidence of postoperative infectious complications was 37.9% in patients with preoperative biliary drainage and 42.4% in patients with biliary contamination, respectively. Patients with extrahepatic bile duct carcinoma, ampulla of Vater carcinoma, and pancreatic carcinoma had a high frequency of preoperative biliary drainage (82.9%, 54.6%, and 50.8%) and bile contamination (34.3%, 26.2%, and 20.2%). Bile contamination was associated with postoperative pancreatic fistula (POPF) Grade B/C, wound infection, and catheter infection. A multivariate logistic regression analysis revealed that biliary contamination (odds ratio 1.33, P = 0.027) was the independent risk factor for POPF Grade B/C. The three most commonly cultured microorganisms from bile (Enterococcus, Klebsiella, and Enterobacter) were identical to those isolated from organ spaces.CONCLUSIONIn patients undergoing PD, bile contamination is related to postoperative infectious complication including POPF Grade B/C. The management of biliary contamination should be standardised for patients who require preoperative biliary drainage for PD, as the main microorganisms are identical in both organ spaces and bile.

Bridge of preoperative biliary drainage is a useful management for patients undergoing pancreaticoduodenectomy

Background/ObjectivesThe aims of this study were to clarify the effect of preoperative biliary drainage (PBD) on postoperative outcomes and the role of preoperative intentional exchange from endoscopic nasobiliary drainage (ENBD) to endoscopic retrograde biliary drainage (ERBD) for patients waiting to undergo pancreaticoduodenectomy (PD). MethodsWe evaluated the effect of PBD and intentional exchange of PBD on the perioperative variables in 292 patients. ResultsA total of 179 (61.3%) of 292 patients received PBD. There was no marked difference in the postoperative outcomes between the patients who did and did not receive PBD. Among the 160 patients who initially received endoscopic PBD, 10 (6.3%) underwent stent exchange for stent dysfunction, 59 (36.9%) who did not develop stent dysfunction underwent intentional stent exchange from ENBD to ERBD (bridge PBD group), and 91 (56.9%) did not receive any stent exchange (unchanged PBD group). The bridge PBD group had a longer duration of PBD (37 days) (p < 0.001) and a shorter preoperative hospital stay after PBD (32 days) (p < 0.001) than the unchanged PBD group (25 and 46 days, respectively); however, there were no significant differences in the postoperative variables. The incidence of stent exchange due to stent dysfunction in the bridge PBD group (11.9%) was lower than that in patients who initially received ERBD (36.0%) (p = 0.015). ConclusionsBridge PBD worked well for extending the duration of PBD without worsening the postoperative outcomes after PD.

Bacteriological profile of patients with periampullary cancer and effect of preoperative biliary drainage on bacterial flora

Aim: This study aims to identify the frequency of bacteriobilia, commonly isolated bacteria and their antibiotic susceptibility pattern from cancer patients with periampullary carcinoma attending a regional cancer center in the North-East India. Materials and Methods: This was a retrospective 1-year study of patients with obstructive jaundice due to periampullary carcinoma treated between January 2018 and December 2018. Intraoperative bile samples were obtained for microbiological analysis after transection of the common bile duct. Bile specimens were transported to the microbiology laboratory, and processing was done according to the standard protocol used in our clinical microbiology laboratory. Results: Intraoperative bile samples were obtained from 27 patients, and in 21 (77.77%) patients, it was culture positive. Stenting was done in 10 (37.07%) patients, and in those who underwent stenting, microbial contamination of bile was increased significantly (80%) compared to 61.90% in those without stenting. Organisms isolated were Escherichia coli 9 (42.85%), Klebsiella pneumonia 7 (33.33%), Pseudomonas 3 (14.28%), and Enterococcus cloacae 2 (9.52%). Carbapenamase producing E. coli(n = 1) and K. pneumonia (n = 1) was isolated from the two stented patient and one was vancomycin-resistant enterococcus (n = 1). Conclusion: Patients who underwent stenting for periampullary carcinoma had a significant risk for acquiring infection with multidrug-resistant bacteria.

Effect of preoperative biliary drainage on cholestasis-associated inflammatory and fibrotic gene signatures in perihilar cholangiocarcinoma.

Preoperative biliary drainage (PBD) is used routinely in the evaluation of patients with potentially resectable perihilar cholangiocarcinoma to relieve cholestasis and improve the liver's resilience to surgery. Little preclinical or translatational data are, however, currently available to guide the use of PBD in this patient group. The effect of PBD on hepatic gene expression profiles was therefore studied by microarray analysis. Drainage affects inflammatory and fibrotic gene signatures.

Oncologic effects of preoperative biliary drainage in resectable hilar cholangiocarcinoma: Percutaneous biliary drainage has no adverse effects on survival.

The objective of the current study was to define long-term survival of patients with resectable hilar cholangiocarcinoma (HCCA) after preoperative percutaneous transhepatic biliary drainage (PTBD) versus endoscopic biliary drainage (EBD). Between 2000 and 2014, 240 patients who underwent curative-intent resection for HCCA were identified at 10 major hepatobiliary centers. Postoperative morbidity and mortality, as well as disease-specific survival (DSS) and recurrence-free survival (RFS) were analyzed among patients. The median decrease in total bilirubin levels after biliary drainage was similar comparing PTBD (n = 104) versus EBD (n = 92) (mg/dL, 4.9 vs 4.9, P = 0.589) before surgery. There was no difference in baseline demographic characteristics, type of surgical procedure performed, final AJCC tumor stage or postoperative morbidity among patients who underwent EBD only versus PTBD (all P > 0.05). Patients who underwent PTBD versus EBD had a comparable long-term DSS (median, 43.7 vs 36.9 months, P = 0.802) and RFS (median, 26.7 vs 24.0 months, P = 0.571). The overall pattern of recurrence relative to regional or distant disease was also the same among patients undergoing PTBD and EBD (P = 0.669) CONCLUSIONS: Oncologic outcomes including DSS and RFS were similar among patients who underwent PTBD versus EBD with no difference in tumor recurrence location.

Disease-free survival following resection in non-ductal periampullary cancers: A retrospective multicenter analysis

BackgroundPredictors of recurrence following pancreaticoduodenectomy are well described for ductal periampullary cancers but lack reliability for non-ductal tumors. The purpose of this study is to analyze the disease-free survival (DFS) and to define the predictors of recurrence following resection for ampullary (AC), bile duct (BDC) and duodenal cancers (DC). Materials and methodsClinico-pathological data of patients operated on between 2001 and 2011 were retrospectively reviewed. The effect of lymphatic invasion was specified using the lymph node ratio (LNR) and the number of positive nodes (NPN), with thresholds calculated with the likelihood ratio. Kaplan–Meier disease-free survival (DFS) curves were compared for all covariates by a log-rank test. Multivariate logistic regression analyses were performed to identify predictors of recurrence. Results135 patients were identified. Mean follow-up was 49 ± 35 months. Median DFS was not reached for AC and was 36 and 18 months for DC and BDC, respectively. Five-year DFS was 52%, 43% and 32% for AC, DC and BDC, respectively. Predictors of recurrence were T4 tumors, neural invasion and preoperative biliary drainage for DC, ≥3 positive nodes and ≥4% loss of BMI for AC, and T3–T4 tumors for BDC. ConclusionLoss of BMI ≥4% is a strong predictor of recurrence in AC, and the recurrence risk increases with the total number of lymph nodes invaded (0; 1–3; ≥4). Only T stage influences recurrence for BDC. Considering DC, the adverse effect of preoperative biliary drainage should be validated in randomized series.
