Safety and efficacy of biliary suprapapillary metal and plastic stents in malignant biliary obstruction: a systematic review and meta-analysis. Surg Endosc 2024:10.1007/s00464-024-11025-0. [PMID: 38987483 DOI: 10.1007/s00464-024-11025-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Accepted: 06/30/2024] [Indexed: 07/12/2024]
Abstract
BACKGROUND AND AIMS Biliary drainage is vital in managing malignant biliary obstruction (MBO). Suprapapillary stenting has emerged as a viable alternative to transpapillary stenting and is performed using inside plastic (iPS) or metal stents (iMS). This meta-analysis aims to evaluate the outcomes of suprapapillary stent placement for MBO. METHODS The Embase, PubMed, and Web of Science databases were systematically searched to include all studies published before September 31, 2023, that reported on the outcomes of suprapapillary stents placed for MBO. Using the random-effect model, the pooled, weight-adjusted event rate estimate for the clinical outcomes was calculated with 95% confidence intervals (CIs). RESULTS Twenty-eight studies were included, with a total of 1401 patients. The pooled clinical success rate was 98.9%. A subgroup analysis yielded non-significant differences between the iPS and iMS groups (99.3% vs. 98.6%, respectively; P = 0.44). The pooled incidence rate of adverse events (AE) with suprapapillary stents was 9.5%. In a subgroup analysis, the incidence of AEs with iPS was 10.7% compared to 9% in the iMS group without a statistical difference (P = 0.32). The most common adverse event was cholangitis (2.2%), followed by pancreatitis (1.1%), cholecystitis (0.5%), and bleeding (0.12%). CONCLUSION When technically feasible, suprapapillary stenting for MBO is a viable endoscopic option with a high clinical success rate and acceptable adverse event rates. Both iPS and iMS exhibit similar efficacy.

Efficacy of Fully Covered Self-Expandable Metal Stents for Distal Biliary Obstruction Caused by Pancreatic Ductal Adenocarcinoma: Primary Metal Stent vs. Metal Stent following Plastic Stent. Cancers (Basel) 2023; 15:cancers15113001. [PMID: 37296962 DOI: 10.3390/cancers15113001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 05/25/2023] [Accepted: 05/30/2023] [Indexed: 06/12/2023] Open
Abstract
Fully covered self-expandable metallic stents (FCSEMSs) are inserted in patients with unresectable pancreatic ductal adenocarcinoma (PDAC) to resolve malignant distal bile duct obstructions. Some patients receive FCSEMSs during primary endoscopic retrograde cholangiopancreatography (ERCP), and others receive FCSEMSs during a later session, after the placement of a plastic stent. We aimed to evaluate the efficacy of FCSEMSs for primary use or following plastic stent placement. A total of 159 patients with pancreatic adenocarcinoma (m:f, 102:57) who had achieved clinical success underwent ERCP with the placement of FCSEMSs for palliation of obstructive jaundice. One-hundred and three patients had received FCSEMSs in a first ERCP, and 56 had received FCSEMSs after prior plastic stenting. Twenty-two patients in the primary metal stent group and 18 in the prior plastic stent group had recurrent biliary obstruction (RBO). The RBO rates and self-expandable metal stent patency duration did not differ between the two groups. An FCSEMS longer than 6 cm was identified as a risk factor for RBO in patients with PDAC. Thus, choosing an appropriate FCSEMS length is an important factor in preventing FCSEMS dysfunction in patients with PDAC with malignant distal bile-duct obstruction.

Modified non-flared fully covered self-expandable metal stent for preoperative biliary drainage in pancreatic cancer. J Gastroenterol Hepatol 2022; 37:225-232. [PMID: 34750863 DOI: 10.1111/jgh.15733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 10/23/2021] [Accepted: 10/29/2021] [Indexed: 12/09/2022]
Abstract
BACKGROUND AND AIM Durable biliary drainage is essential in patients with pancreatic cancer in the era of effective neoadjuvant chemotherapy (NACT). Plastic stent (PS) tends to occlude easily, and current metal stents are designed for nonresectable cancer. We evaluated the efficacy of a modified non-flared fully covered self-expandable metal stent (M-FCSEMS) during the perioperative period in patients with resectable or borderline resectable pancreatic cancer. METHODS Consecutive patients with resectable or borderline resectable pancreatic ductal adenocarcinoma had a 12-mm M-FCSEMS (M-FCSEMS group) or 7-Fr PS (PS group) placed for biliary decompression before NACT or curative-intent surgery. The primary outcome was the re-intervention rate, and secondary outcomes were technical success, stent patency, and adverse events (AEs). RESULTS Endoscopic stent placement was technically successful in all 60 patients. Twenty-three patients underwent surgery and 37 NACT before surgery. Re-intervention was performed in 10.0% (3/30) of patients in the M-FCSEMS group and 36.7% (11/30) of patients in the PS group (P = 0.030). The stent patency at 180 days was 89.8% (95% confidence interval, 77.3-100.0%) in the M-FCSEMS group and 30.2% (95% confidence interval, 11.4-80.0%) in the PS group (P < 0.0001). Stent-related AEs occurred in 10.0% (3/30) in the M-FCSEMS group and 40.0% (12/30) in the PS group (P = 0.015). Surgery-related AEs occurred in 10.5% (2/19) and 14.3% (3/21) in the M-FCSEMS and PS groups (P = 0.549). CONCLUSIONS Modified non-flared fully covered self-expandable metal stents are effective and safe for durable biliary drainage in patients with resectable or borderline resectable pancreatic cancer during the perioperative period.

Abstract
Following high-quality imaging studies for staging, endoscopic ultrasound examination fine needle aspiration/biopsy is the preferred modality for tissue diagnosis of pancreatic cancer. Endoscopic retrograde cholangiopancreatography with metal stent placement is used for palliation of malignant biliary obstruction. Metal stents can be placed in patients with resectable pancreatic cancer in whom surgery is going to be delayed. For palliation of gastric outlet obstruction, endoscopic enteral stenting is often selected because of its less invasiveness. Endoscopic ultrasound-guided biliary drainage for malignant biliary obstruction or gastrojejunostomy for gastric outlet obstruction are emerging less invasive techniques as compared with palliative surgery.

Nanomagnetic Actuation of Hybrid Stents for Hyperthermia Treatment of Hollow Organ Tumors. NANOMATERIALS 2021; 11:nano11030618.

Abstract
This paper describes a magnetic nanotechnology that locally enables hyperthermia treatment of hollow organ tumors by using polymer hybrid stents with incorporated magnetic nanoparticles (MNP). The hybrid stents are implanted and activated in an alternating magnetic field to generate therapeutically effective heat, thereby destroying the tumor. Here, we demonstrate the feasibility of nanomagnetic actuation of three prototype hybrid stents for hyperthermia treatment of hollow organ tumors. The results show that the heating efficiency of stent filaments increases with frequency from approximately 60 W/gFe (95 kHz) to approximately 250 W/gFe (270 kHz). The same trend is observed for the variation of magnetic field amplitude; however, heating efficiency saturates at approximately 30 kA/m. MNP immobilization strongly influences heating efficiency showing a relative difference in heating output of up to 60% compared to that of freely dispersed MNP. The stents showed uniformly distributed heat on their surface reaching therapeutically effective temperatures of 43 °C and were tested in an explanted pig bile duct for their biological safety. Nanomagnetic actuation of hybrid stents opens new possibilities in cancer treatment of hollow organ tumors.

Abstract
BACKGROUND While neoadjuvant chemotherapy and chemoradiotherapy (NACRT) for pancreatic head cancer are effective, preoperative endoscopic biliary drainage (EBD) is necessary for managing obstructive jaundice and cholangitis during the preoperative waiting period. Nevertheless, ideal choice of stent type is unclear. We compared plastic stents (PS) and metal stents (MS) in these situations. METHODS We retrospectively studied 43 patients who successfully underwent preoperative EBD prior to NACRT for pancreatic head cancer at a single institution. We divided patients into PS (n = 22) and MS (n = 21) groups. The primary outcome was the rate of re-interventional drainage rate before surgery. Secondary outcomes were rates of EBD-associated and postoperative complications and total costs in the pre- and perioperative periods. RESULTS The re-intervention rate was significantly greater in the PS group than in the MS group (95% vs 4.8%, respectively, P < 0.05). EBD-associated and postoperative complications were significantly less common in the MS group (P < 0.05). The average total preoperative medical costs were significantly lower in the MS group (PS vs MS: 528,597 vs 395,891 JPY, P = 0.004). CONCLUSIONS MS can be the first choice for EBD in patients undergoing NACRT for pancreatic head cancer. MS may be less costly overall.

Abstract
Background and study aims Self-expandable metallic stents (SEMS) are now widely used even for patients with borderline resectable (BR) pancreatic cancer (PC), as neoadjuvant therapy has become common. Therefore, we conducted this study to evaluate safety of SEMS placement in the population including BR PC and to explore risk factors for recurrent biliary obstruction (RBO), pancreatitis, and cholecystitis. Patients and methods We retrospectively investigated consecutive patients with PC who received initial SEMS between January 2015 and March 2019. We compared time to RBO (TRBO), causes of RBO, and stent-related adverse events (AEs) according to resectability status. Univariate and multivariate analyses were performed to explore risk factors for TRBO, pancreatitis, and cholecystitis. Results A total of 135 patients were included (BR 31 and unresectable [UR] 104). Stent-related AEs occurred in 39 patients: pancreatitis 14 (mild/moderate/severe 1/6/7), cholecystitis 12, and non-occluding cholangitis 13. TRBO, causes of RBO, and stent-related AEs were not significantly different according to resectability status. Overall rate of RBO was higher in UR PC due to the longer follow-up period. Sharp common bile duct (CBD) angulation was an independent risk factor for short duration of TRBO. High pancreatic volume index and SEMS of high axial force were independent risk factors for pancreatitis, whereas tumor involvement to orifice of cystic duct was the only risk factor for cholecystitis. Conclusions We demonstrated that SEMS can be safely deployed even in patients with BR PC. Sharp CBD angulation and high pancreatic volume index were identified as novel risk factors for RBO and pancreatitis, respectively, after SEMS placement.

Abstract
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.

Abstract
INTRODUCTION Preoperative biliary drainage has been widely used to treat patients with malignant biliary obstruction. However, it is still unclear which method is more effective: internal drainage or external drainage. Thus, we carried out a meta-analysis to compare the safety and efficacy of the two drainage methods in treatment of malignant biliary obstruction in terms of preoperative and postoperative complications. MATERIAL AND METHODS We conducted a literature search of Medline, EMBASE, PubMed, Ovid journals and the Cochrane Library, and compared internal drainage and external drainage in malignant biliary obstruction patients. The pre- and postoperative complications, stent dysfunction rate and mortality were analyzed. RESULTS Ten published studies (n = 1464 patients) were included in this meta-analysis. We found that patients with malignant biliary obstruction who received external drainage showed reductions in the preoperative cholangitis rate (OR = 0.33, 95% CI: 0.24-0.44, p < 0.00001), the incidence of stent dysfunction (OR = 0.41, 95% CI: 0.30-0.57, p < 0.00001), and total morbidity (OR = 0.34, 95% CI: 0.23-0.50, p < 0.00001) compared with patients who received internal drainage. CONCLUSIONS The current meta-analysis indicates that external drainage is better than internal drainage for malignant biliary obstruction in terms of the preoperative cholangitis rate, the incidence of stent dysfunction and total morbidity, etc. However, the findings need to be confirmed by randomized controlled trials.

Abstract
BACKGROUND AND AIM Biliary obstruction can impair the effectiveness of neo-adjuvant chemotherapy. This study was designed to compare biliary stenting with covered self-expandable metal stents (FCSEMS) and plastic stents (PS) in patients with biliary obstruction caused by borderline resectable pancreatic cancer (BRPC) who were undergoing neo-adjuvant chemotherapy during preoperative biliary drainage. METHODS This single-center, comparative, randomized, superiority study was designed to compare FCSEMS with PS for drainage of biliary obstruction of BRPC. Twenty two eligible patients providing informed consent will be randomized 1:1 by computer to either FCSEMS or PS for endoscopic retrograde biliary drainage (ERBD). All subsequent clinical interventions, including crossover to alternative procedures, will be at the discretion of the treating physician based on standard clinical care. The primary outcomes will be the rates and causes of stent dysfunction during preoperative biliary drainage. Other outcomes include time required for ERBD, adverse events related to ERBD, period from ERBD to surgery, percentage of patients able to undergo surgery, operation time, intraoperative bleeding volume, postoperative adverse events, and postoperative hospitalization. Subjects, treating clinicians, and outcome assessors will not be blinded to assignment. DISCUSSION This study is intended to determine whether FCSEMS or PS is the better biliary stent for ERBD for management of patients with biliary obstruction of BRPC, a common clinical dilemma that has not yet been investigated in randomized trials.

[PMID: 31700238 PMCID: PMC6826073 DOI: 10.20524/aog.2019.0427] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Accepted: 09/23/2019] [Indexed: 12/15/2022] Open
Abstract
Background: In patients with distal malignant biliary obstruction (MBO), endoscopic biliary drainage using the conventional self-expandable metal stent (SEMS) is the gold standard method for palliative treatment. However, there are limited data on the role of the antireflux valve metal stent (ARVMS). The aim of this study was to compare the safety and efficacy of ARVMS and SEMS in patients with distal MBO. Methods: We searched PubMed, Ovid, Embase and the Cochrane Library from inception until April 2019 for relevant randomized controlled trials (RCTs). The selected studies provided data regarding technical and clinical success rates, adverse events, and stent dysfunction. Data were meta-analyzed using RevMan software. Results: Three RCTs were selected, enrolling 293 patients (147 ARVMS and 146 SEMS). The rates of technical success were 95.23% and 99.31% for ARVMS and SEMS groups, respectively (odds ratio [OR] 0.13, 95% confidence interval [CI] 0.01-1.06; P=0.06). The clinical success rates were 91.57% and 89.36% for ARVMS and SEMS groups, respectively (OR 1.30, 95%CI 0.48-3.51; P=0.61). There was no significant difference between the ARVMS and SEMS groups in terms of adverse events (OR 0.61, 95%CI 0.35-1.05; P=0.07) or stent dysfunction (OR 0.77, 95%CI 0.31-1.95; P=0.58), while the incidence of stent occlusion was significantly lower in the ARVMS group (OR 0.44, 95%CI 0.26-0.76; P=0.003). Conclusion: Our study showed that ARVMS and SEMS had similar technical and clinical success rates. Adverse events were comparable between the 2 arms; however, ARVMS was associated with a lower risk of stent occlusion. Larger RCTs are required to verify the benefit of ARVMS in distal MBO patients.

Covered and uncovered biliary metal stents provide similar relief of biliary obstruction during neoadjuvant therapy in pancreatic cancer: a randomized trial. Gastrointest Endosc 2019; 90:602-612.e4.

Abstract
BACKGROUND AND AIMS Preoperative biliary drainage with self-expanding metal stents (SEMSs) brings liver function within an acceptable range in preparation for neoadjuvant therapy (NATx) and provides relief of obstructive symptoms in patients with pancreatic cancer. We compared fully-covered SEMSs (FCSEMSs) and uncovered SEMSs (UCSEMSs) for sustained biliary drainage before and during NATx. METHODS Patients with pancreatic cancer and planned NATx who need treatment of jaundice and/or cholestasis before pancreaticoduodenectomy were randomized to FCSEMSs versus UCSEMSs. The primary endpoint was sustained biliary drainage, defined as the absence of reinterventions for biliary obstructive symptoms, and was assessed from SEMS placement until curative intent surgery or at 1 year. RESULTS The intention-to-treat population included 119 patients (59 FCSEMSs, 60 UCSEMSs). Sustained biliary drainage was equally successful with FCSEMSs and UCSEMSs (72.2% vs 72.9%, noninferiority P = .01). Reasons for FCSEMS and UCSEMS failure differed significantly between the groups and included tumor ingrowth in 0% versus 16.7% (P < .01), and stent migration in 6.8% versus 0% (P = .03), respectively. Serious adverse event rates related to stent placement were not significantly different in both groups (23.7% [14/59] vs 20.0% [12/60], P = .66), as were acute cholecystitis rates when the gallbladder was in situ (9.3% [4/43] vs 4.8% [2/42], P = .68) for FCSEMSs and UCSEMSs, respectively. In our study, independent of stent type, predictors of reinterventions were 4-cm stent length and presence of the gallbladder. CONCLUSION FCSEMSs and UCSEMSs provide similar preoperative management of biliary obstruction in patients with pancreatic cancer receiving NATx, but mechanisms of stent dysfunction depend on stent type, stent length, and presence of the gallbladder.

Modified non-flared fully covered self-expandable metal stent versus plastic stent for preoperative biliary drainage in patients with resectable malignant biliary obstruction. J Gastroenterol Hepatol 2019; 34:1590-1596. [PMID: 30618170 DOI: 10.1111/jgh.14600] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Revised: 12/31/2018] [Accepted: 01/04/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND AND AIM Fully covered self-expandable metal stents (FCSEMS) may be better than plastic stents (PS) for preoperative biliary drainage (PBD) to relieve cholangitis or jaundice for resectable malignant biliary obstruction (MBO). However, modification of current FCSEMS designed originally for nonresectable MBO is needed to be a proper stent for PBD. The aim of this study was to evaluate the possible superiority of non-flared modified FCSEMS (M-FCSEMS) with 12-mm diameter and waist of central portion over PS in patients with resectable MBO. METHODS Eighty-five consecutive patients underwent PBD followed by operation from August 2015 to December 2017. In each M-FCSEMS and PS group, 29 patients were matched for age, sex, body mass index, and preoperative albumin and bilirubin levels. RESULTS The overall technical success rates of PBD using M-FCSEMS and PS were 100%. The time to operation was similar between groups (18.6 ± 10.8 vs 19.3 ± 11.6 days, respectively; P = 0.843). The prevalence of PBD-related adverse events (AEs) was 6.9% (2/29) in the M-FCSEMS group versus 27.6% (8/29) in the PS group (P = 0.037). Re-intervention before operation was required in 20.7% (6/29) of patients in the PS group but no patients in the M-FCSEMS group (P = 0.023). No differences were found between perioperative AEs in the M-FCSEMS and PS groups (27.5% vs 31.0%, respectively; P = 0.773). CONCLUSION Modified FCSEMS led to lower PBD-related AEs, re-intervention rate, and comparable perioperative AEs compared with PS. M-FCSEMS may be a potential novel stent for PBD in patients with resectable MBO.

Abstract
Pancreatic cancer is the 11th most common cancer in the UK and has the worst prognosis of any tumour with minimal improvements in survival over recent decades. As most patients are either ineligible for surgery or may decline chemotherapy, the emphasis is on control of symptoms and management of complications such as poor nutritional status. The time period between informing the patient of their diagnosis and commencing cancer treatments presents a valuable opportunity to proactively identify and treat symptoms to optimise patients' overall well-being. The 'bridging clinic', delivered by a range of healthcare professionals from gastroenterologists to nurse practitioners, can provide this interface where patients are first informed of their diagnosis and second supportive therapies offered. In this article, we provide a structure for instituting such supportive therapies at the bridging clinic. The components of the clinic are summarised using the mnemonic INDASH (Information/Nutrition/Diabetes and Depression/Analgesia/Stenting/Hereditary) and each is discussed in detail below.

Abstract
BACKGROUND Controversy remains about the best pre-operative management of jaundice in patients with resectable pancreatic head cancer (RPC) undergoing planned pancreaticoduodenectomy (PD). OBJECTIVE The aim of this study was to compare rates of post-operative complications in patients undergoing four pre-operative approaches (POA): preoperative biliary drainage with plastic stent (PBD-PS), metal stent (PBD-MS), and percutaneous transhepatic drain (PBD-PT), or no pre-operative biliary drainage (NPBD). METHOD A study was included in the systematic review if it assessed the effects of PBD on post-operative outcomes in jaundiced patients with RPC. Endpoints were the rate of any post-operative complication, wound infection, intra-abdominal infection and post-operative bleeding. A network meta-analysis (NMA) was performed to rank the POAs from the best to worst, for each outcome. RESULTS Thirty-two studies were included in the systematic review. Ten out of 32 studies included in the systematic review reported at least one of the 4 outcomes of interest and thus were used for NMA. The calculated odds ratios and P-scores ranked NPBD as the best approach. There was insufficient evidence to determine the best modality of PBD among PBD-PS, PBD-MS and PBD-PT. CONCLUSIONS No preoperative biliary drainage may be the best management of preoperative jaundice in patients with RPC before PD. Further studies are needed to determine the best modality in patients that need PBD.

Abstract
BACKGROUND AND STUDY AIMS Durable biliary drainage is essential during neoadjuvant therapy (NAT) in patients with pancreatic cancer who present with biliary obstruction. Plastic stents (PS) tend to occlude readily, resulting in delay/interruption of treatment. Our aim was to evaluate the safety and efficacy of self-expanding metal stents (SEMS) for biliary drainage in patients receiving NAT for pancreatic cancer. PATIENTS AND METHODS From 2009 to 2014, all consecutive patients with resectable pancreatic cancer at one tertiary center had SEMS placed for biliary drainage before NAT was started. Data on biliary drainage efficacy, stent malfunction rates and procedural adverse events were collected. RESULTS One hundred forty-two consecutive patients with pancreatic cancer (mean age 66 ± 9 SD years; 81 male, 61 female; 67 resectable, 75 borderline resectable) were enrolled. Eight-seven patients (61 %) had prior PS exchanged to SEMS and 55 (39 %) had SEMS placed upfront. Median duration from SEMS placement to the end of NAT/surgery was 111 days (range 44 - 282). During NAT, SEMS malfunction requiring reintervention occurred in 16 patients (11.2 %): tissue ingrowth 11, stent occlusion from food 6, stent migration 3, incomplete expansion 1, "tissue cheese-cutter" effect 1, and cystic duct obstruction 1. On subgroup analysis, no correlation between SEMS malfunction and stage of disease, prior PS, or duration of NAT was found (r 2 = 0.05, P = 0.34). Presence of SEMS in situ did not affect pancreaticoduodenectomy. CONCLUSION SEMS provide safe, effective and durable biliary drainage during NAT for pancreas cancer. Previously placed PS can be exchanged for SEMS. SEMS do not require removal prior to surgery.

Abstract
Objectives To compare the use of an antireflux metal stent (ARMS) with that of a conventional covered self-expandable metal stent (c-CSEMS) for initial stenting of malignant distal biliary obstruction (MDBO). Materials and Methods We retrospectively investigated 59 consecutive patients with unresectable MDBO undergoing initial endoscopic biliary drainage. ARMS was used in 32 patients and c-CSEMS in 27. Technical success, functional success, complications, causes of recurrent biliary obstruction (RBO), time to RBO (TRBO), and reintervention were compared between the groups. Results Stent placement was technically successful in all patients. There were no significant intergroup differences in functional success (ARMS [96.9%] versus c-CSEMS [96.2%]), complications (6.2 versus 7.4%), and RBO (48.4 versus 42.3%). Food impaction was significantly less frequent for ARMS than for c-CSEMS (P = 0.037), but TRBO did not differ significantly between the groups (log-rank test, P = 0.967). The median TRBO was 180.0 [interquartile range (IQR), 114.0–349.0] days for ARMS and 137.0 [IQR, 87.0–442.0] days for c-CSEMS. In both groups, reintervention for RBO was successfully completed in all patients thus treated. Conclusion ARMS offers no advantage for initial stent placement, but food impaction is significantly prevented by the antireflux valve.

Abstract
Painless jaundice is a harbinger of malignant biliary obstruction, with the majority of cases due to pancreatic adenocarcinoma. Despite advances in treatment, including improved surgical techniques and neoadjuvant (preoperative) chemotherapy, long-term survival from pancreatic cancer is rare. This lack of significant improvement in outcomes is believed to be due to multiple reasons, including the advanced stage at diagnosis and lack of an adequate biomarker for screening and early detection, prior to the onset of jaundice or epigastric pain. Close attention is required to select appropriate patients for preoperative biliary decompression, and to prevent morbid complications from biliary drainage procedures, such as pancreatitis and cholangitis. Use of small caliber plastic biliary stents during endoscopic retrograde cholangiopancreatography should be minimized, as metal stents have increased area for improved bile flow and a reduced risk of adverse events during neoadjuvant therapy. Efforts are underway by translational scientists, radiologists, oncologists, surgeons, and gastroenterologists to augment lifespan for our patients and to more readily treat this deadly disease. In this review, the authors discuss the rationale and techniques of endoscopic biliary intervention, mainly focusing on malignant biliary obstruction by pancreatic cancer.

Abstract
BACKGROUND AND STUDY AIMS Recent literature suggests that chemo(radio)therapy might reduce the patency of plastic stents in patients with malignant biliary obstruction. Whether this might also be valid for other types of stents is unknown. The aim of this study was to determine the influence of chemo(radio)therapy on the patency of fully-covered self-expandable metal stents (FCSEMSs) and plastic stents. PATIENTS AND METHODS We retrospectively reviewed the electronic medical records of patients with distal malignant biliary obstruction who underwent biliary stent placement between April 2001 and July 2015. Primary outcome was duration of stent patency. Secondary outcome was stent patency at 3 and 6 months. We used Kaplan-Meier survival analyses to compare stent patency rates between patients who received chemo(radio)therapy and patients who did not. RESULTS A total of 291 biliary stents (151 metal and 140 plastic) were identified. The median cumulative stent patency of FCSEMSs did not differ between patients receiving chemo(radio)therapy (n = 51) and those (n = 100) who did not ( P = 0.70, log-rank test). The estimated cumulative stent patency of plastic stents was also comparable in 99 patients without and 41 patients with chemo(radio)therapy ( P = 0.73, log-rank test). At 3 and 6 months, FCSEMS patency rates were 87 % and 83 % in patients without chemo(radio)therapy and 96 % and 83 % in patients with therapy, respectively. Plastic patency rates were 69 % and 55 % in patients without and 85 % and 39 % in patients with therapy, respectively. After 1 year, 78 % of the FCSEMSs were still patent in patients without chemo(radio)therapy and 69 % of the FCSEMSs were still patent in patients with therapy. CONCLUSION Our data indicate that chemo(radio)therapy does not reduce the patency of biliary fully-covered metal and plastic stents.

Abstract
BACKGROUND AND STUDY AIMS Preoperative biliary drainage in patients with periampullary tumors and jaundice has been popularized to improve the quality of life and minimize the risks associated with subsequent radical surgery. The aim of this study was to investigate the possible superiority of self-expandable metal stents (SEMS) over plastic stents, by comparing the amount of bacteria in intraoperatively collected bile and using this variable as a proxy for the efficacy of the respective biliary drainage modalities. PATIENTS AND METHODS In this randomized clinical trial, 92 patients with obstructive jaundice were enrolled; 45 were allocated to the plastic stent group and 47 to the SEMS group. The primary outcome was the extent and magnitude of biliary bacterial growth at the time of surgical exploration. Secondary outcomes were: macroscopic grading of inflammation of the stented bile ducts, occurrence of adverse events after stenting, stent dysfunction, recognized surgical complexities, and incidence of postoperative complications. RESULTS The patients were well matched regarding clinical and disease-specific characteristics. At surgery, there were no group differences in the bacterial amount and composition of the bile cultures or the perceived difficulty of surgical dissection. During the preoperative biliary drainage period, more instances of stent dysfunction requiring stent replacement were recorded in the plastic stent group (19 % vs. 0 %; P = 0.03). Postoperative complications in patients who underwent curative surgery were more common in patients with plastic stents (72 % vs. 52 %), among which clinically significant leakage from the pancreatic anastomoses seemed to predominate (12 % vs. 3.7 %); however, none of these differences in postoperative adverse events reached statistical significance. CONCLUSION This randomized clinical study was unable to demonstrate any superiority of SEMS in the efficacy of preoperative bile drainage, as assessed by the amount of bacteria in the intraoperatively collected bile. However, some data in favor of SEMS were observed among the clinical secondary outcomes variables (preoperative stent exchange rates) without increases in local inflammatory reactions.

Abstract
Distal malignant biliary obstruction (MBO) leads to obstructive jaundice as a result of when the bile excretion from the liver is disturbed and induces hepatic failure and sepsis, which when complicated with cholangitis, it becomes necessary to perform drainage for the MBO. For biliary drainage, we can perform a surgical bypass operation, percutaneous transhepatic biliary drainage (PTBD), endoscopic biliary drainage (EBD) via duodenal papilla, or endoscopic ultrasound (EUS)-guided biliary drainage (EUS-BD), which is a transgastrointestinal biliary drainage. Although currently we usually perform EBD for distal MBO to begin with, the choice is different for biliary drainage in patients in whom EBD has failed in a preoperative case or an unresectable case. In other words, we choose PTBD for preoperative cases, and PTBD or EUS-BD according to the ability of the institution for their procedures when EBD has failed. It is desirable not to choose a plastic stent (PS) but a self-expandable metallic stent (SEMS), in particular for the unresectable cases of pancreatic cancer it is desirable not to choose an uncovered SEMS but a covered SEMS in EBD. Nevertheless, further examinations are expected to decide which, a covered or uncovered SEMS, we should choose in unresectable biliary tract cancer (BTC) and whether we should select PS, SEMS or ENBD in preoperative cases.

Abstract
Early diagnosis and accurate staging of pancreatic cancer is very important to plan optimal management strategy. Endoscopy plays an important role in the diagnosis and management of pancreatic cancer. Endoscopic ultrasound imaging (EUS) is the most sensitive modality for diagnosis, especially for small pancreatic tumors; it also allows tissue acquisition for histological diagnosis. Computed tomography scanning and EUS play complementary roles in staging and are comparable in determining resectability. Endoscopic retrograde cholangiopancreatography allows tissue sampling but is limited to palliative biliary drainage in most cases. In this article, we review the role of endoscopy in the diagnosis and management of pancreatic adenocarcinoma, with special emphasis on the use of endoscopic ultrasound and endoscopic retrograde cholangiopancreatography (ERCP).

Abstract
INTRODUCTION In pancreatic cancer, preoperative biliary drainage (PBD) increases complications compared with surgery without PBD, demonstrated by a recent randomised controlled trial (RCT). This outcome might be related to the plastic endoprosthesis used. Metal stents may reduce the PBD-related complications risk. METHODS A prospective multicentre cohort study was performed including patients with obstructive jaundice due to pancreatic cancer, scheduled to undergo PBD before surgery. This cohort was added to the earlier RCT (ISRCTN31939699). The RCT protocol was adhered to, except PBD was performed with a fully covered self-expandable metal stent (FCSEMS). This FCSEMS cohort was compared with the RCT's plastic stent cohort. PBD-related complications were the primary outcome. Three-group comparison of overall complications including early surgery patients was performed. RESULTS 53 patients underwent PBD with FCSEMS compared with 102 patients treated with plastic stents. Patients' characteristics did not differ. PBD-related complication rates were 24% in the FCSEMS group vs 46% in the plastic stent group (relative risk of plastic stent use 1.9, 95% CI 1.1 to 3.2, p=0.011). Stent-related complications (occlusion and exchange) were 6% vs 31%. Surgical complications did not differ, 40% vs 47%. Overall complication rates for the FCSEMS, plastic stent and early surgery groups were 51% vs 74% vs 39%. CONCLUSIONS For PBD in pancreatic cancer, FCSEMS yield a better outcome compared with plastic stents. Although early surgery without PBD remains the treatment of choice, FCSEMS should be preferred over plastic stents whenever PBD is indicated. TRIAL REGISTRATION NUMBER Dutch Trial Registry (NTR3142).

Abstract
In the past year, automation has become more and more important in the field of elemental and structural chemical analysis to reduce the high degree of manual operation and processing time as well as human errors. Thus, a high number of data points are generated, which requires fast and automated data evaluation. To handle the preprocessed export data from different analytical devices with software from various vendors offering a standardized solution without any programming knowledge should be preferred. In modern laboratories, multiple users will use this software on multiple personal computers with different operating systems (e.g., Windows, Macintosh, Linux). Also, mobile devices such as smartphones and tablets have gained growing importance. The developed software, Project Analytical Data Evaluation (ADE), is implemented as a web application. To transmit the preevaluated data from the device software to the Project ADE, the exported XML report files are detected and the included data are imported into the entities database using the Data Upload software. Different calculation types of a sample within one measurement series (e.g., method validation) are identified using information tags inside the sample name. The results are presented in tables and diagrams on different information levels (general, detailed for one analyte or sample).

Abstract
Pancreatic cancer remains one of the most lethal malignancies with little improvement in survival over the past several decades in spite of advances in imaging, risk factor identification, surgical technique and chemotherapy. This disappointing outcome is mainly due to failures to make an early diagnosis. In fact, the majority of the patients present with inoperable advanced stages of the disease. Though some of the new tumor markers are promising, we are still in search of the one that has a high sensitivity and accuracy, yet is inexpensive and easy to obtain. The paradigm of management has shifted from up-front surgery followed by adjuvant chemotherapy to neoadjuvant chemoradiation followed by surgery, especially for borderline resectable cancers and even for some resectable cancers. In this article, we will critically assess the limitations of tumor markers and review the advancements in endoscopic techniques in the management of pancreatic cancer.

Abstract
BACKGROUND Preoperative biliary drainage (PBD) with stenting increases complications compared with surgery without PBD. Metallic stents are considered superior to plastic stents when considering stent-related complications. Aim of the present systematic review and meta-analysis is to compare the rate of endoscopic re-intervention before surgery and postoperative outcomes of metal versus plastic stents in patients with resectable periampullary or pancreatic head neoplasms. METHODS We conducted a bibliographic research using the National Library of Medicine's PubMed database, including both randomized controlled trials (RCTs) and non-RCTs. Quantitative synthesis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Statistical heterogeneity was assessed using the I(2) tests. RESULTS One RCT and four non-RCTs were selected, including 704 patients. Of these, 202 patients (29.5%) were treated with metal stents and 502 (70.5%) with plastic stents. The majority of patients (86.4%) had pancreatic cancer. The rate of endoscopic re-intervention after preoperative biliary drainage was significantly lower in the metal stent (3.4%) than in the plastic stent (14.8%) group (p < 0.0001). The rate of postoperative pancreatic fistula was significantly lower in the meta stent group as well (5.1% versus 11.8%, p = 0.04). The rate of post-operative surgical complications and of - post-operative mortality did not differ between the two groups. CONCLUSIONS Although the present systematic review and meta-analysis demonstrates that metal stent are more effective than plastic stents for PBD in patients with resectable periampullary tumors, randomized controlled trials are needed in order to confirm these data with a higher level of evidence.

Abstract
AIM: To determine the optimal method of endoscopic preoperative biliary drainage for malignant distal biliary obstruction.
METHODS: Multicenter retrospective study was conducted in patients who underwent plastic stent (PS) or nasobiliary catheter (NBC) placement for resectable malignant distal biliary obstruction followed by surgery between January 2010 and March 2012. Procedure-related adverse events, stent/catheter dysfunction (occlusion or migration of PS/NBC, development of cholangitis, or other conditions that required repeat endoscopic biliary intervention), and jaundice resolution (bilirubin level < 3.0 mg/dL) were evaluated. Cumulative incidence of jaundice resolution and dysfunction of PS/NBC were estimated using competing risk analysis. Patient characteristics and preoperative biliary drainage were also evaluated for association with the time to jaundice resolution and PS/NBC dysfunction using competing risk regression analysis.
RESULTS: In total, 419 patients were included in the study (PS, 253 and NBC, 166). Primary cancers included pancreatic cancer in 194 patients (46%), bile duct cancer in 172 (41%), gallbladder cancer in three (1%), and ampullary cancer in 50 (12%). The median serum total bilirubin was 7.8 mg/dL and 324 patients (77%) had ≥ 3.0 mg/dL. During the median time to surgery of 29 d [interquartile range (IQR), 30-39 d]. PS/NBC dysfunction rate was 35% for PS and 18% for NBC [Subdistribution hazard ratio (SHR) = 4.76; 95%CI: 2.44-10.0, P < 0.001]; the pig-tailed tip was a risk factor for PS dysfunction. Jaundice resolution was achieved in 85% of patients and did not depend on the drainage method (PS or NBC).
CONCLUSION: PS has insufficient patency for preoperative biliary drainage. Given the drawbacks of external drainage via NBC, an alternative method of internal drainage should be explored.

Abstract
BACKGROUND/PURPOSE Recent studies suggest that there is no significant benefit and that there may be significantly higher morbidity rates in pancreatic cancer patients who undergo preoperative plastic stent placement for obstructive jaundice. This review attempts to define the role of stenting in patients with pancreatic cancer and malignant obstructive jaundice. The latter includes patients unresectable for cure, those who are too frail to withstand an operation, the occasional patient who presents with cholangitis, and those patients who will have a significant delay in surgery because of preoperative neoadjuvant therapy. METHODS Literature review. A therapeutic endoscopy team member of a multidisciplinary team which evaluates and treats >250 pancreatic cancer patients yearly. RESULTS There are 5 historical randomized controlled trials (RCTs) and 1 current RCT demonstrating no significant benefit in preoperatively decompressing jaundiced patients with pancreatic malignancy with percutaneously placed tubes or endoscopically inserted plastic stents. There are 5 RCTs defining a longer patency rate with self-expandable metal stents (SEMS) compared to plastic prostheses suggesting that in the setting of palliation as well as the use of neoadjuvant therapy for resectable or borderline resectable patients, SEMS placement is preferable. CONCLUSIONS Despite data demonstrating lack of efficacy and potential harm in decompressing the biliary tree as opposed to early surgery in jaundiced patients with pancreatic malignancy, endoscopic retrograde cholangiopancreatography with SEMS insertion remains an invaluable palliative modality in non-resectable patients as well as those in whom contemplated resection is delayed in order to give neoadjuvant therapy.

Abstract
Objective. To elucidate the optimum preoperative biliary drainage method for patients with pancreatic cancer treated with neoadjuvant chemotherapy (NAC). Material and Methods. From January 2010 through December 2014, 20 patients with borderline resectable pancreatic cancer underwent preoperative biliary drainage and NAC with a plastic or metallic stent and received NAC at Hiroshima University Hospital. We retrospectively analyzed delayed NAC and complication rates due to biliary drainage, effect of stent type on perioperative factors, and hospitalization costs from diagnosis to surgery. Results. There were 11 cases of preoperative biliary drainage with plastic stents and nine metallic stents. The median age was 64.5 years; delayed NAC occurred in 9 cases with plastic stent and 1 case with metallic stent (p = 0.01). The complication rates due to biliary drainage were 0% (0/9) with metallic stents and 72.7% (8/11) with plastic stents (p = 0.01). Cumulative rates of complications determined with the Kaplan-Meier method on day 90 were 60% with plastic stents and 0% with metallic stents (log-rank test, p = 0.012). There were no significant differences between group in perioperative factors or hospitalization costs from diagnosis to surgery. Conclusions. Metallic stent implantation may be effective for preoperative biliary drainage for pancreatic cancer treated with NAC.

Abstract
Endoscopic stent placement is a common primary management therapy for benign and malignant biliary strictures. However, continuous use of stents is limited by occlusion and migration. Stent technology has evolved significantly over the past two decades to reduce these problems. The purpose of this article is to review current guidelines in managing malignant and benign biliary obstructions, current endoscopic techniques for stent placement, and emerging stent technology. What began as a simple plastic stent technology has evolved significantly to include uncovered, partially covered, and fully covered self-expanding metal stents (SEMS) as well as magnetic, bioabsorbable, drug-eluting, and antireflux stents.(1).

Abstract
BACKGROUND Plastic stents in patients with biliary obstruction caused by pancreatic adenocarcinoma are typically exchanged at 3-month intervals. Plastic stents may have reduced durability in patients receiving chemotherapy. OBJECTIVE To determine the duration of plastic biliary stent patency in patients undergoing chemotherapy for pancreatic adenocarcinoma. DESIGN Retrospective, multicenter cohort study. SETTING Three tertiary academic referral centers. PATIENTS A total of 173 patients receiving downstaging chemotherapy for locally advanced or borderline resectable pancreatic adenocarcinoma from 1996 to 2013. INTERVENTIONS Placement of 10F or larger plastic biliary stents. MAIN OUTCOME MEASUREMENTS Primary outcome was overall duration of stent patency. Secondary outcomes included the incidence of premature stent exchange (because of cholangitis or jaundice) and hospitalization rates. RESULTS A total of 233 plastic stents were placed, and the overall median duration of stent patency was 53 days (interquartile range [IQR] 25-99 days). Eighty-seven stents were removed at the time of surgical resection, and 63 stents were exchanged routinely per protocol. The remaining 83 stent exchanges were performed for worsening liver function test results, jaundice, or cholangitis, representing a 35.6% rate of premature stent exchange. The median stent patency duration in the premature stent exchange group was 49 days (IQR 25-91 days) with a 44.6% hospitalization rate. The overall rate of cholangitis was 15.0% of stent exchanges, occurring a median of 56 days after stent placement (IQR 26-89 days). LIMITATIONS Retrospective study. CONCLUSIONS Plastic biliary stents placed during chemotherapy/chemoradiation for pancreatic adenocarcinoma have a shorter-than-expected patency duration, and a substantial number of patients will require premature stent exchange. Consideration should be given to shortening the interval for plastic biliary stent exchange.

Abstract
The goal of this study was to systematically review the effects of biliary stenting on postoperative morbidity and mortality of patients with obstructive jaundice. PubMed, Embase, Cochrane Library, and other relevant databases were searched by computer and manually for published and unpublished studies on the impact of preoperative biliary drainage on patients with obstructive jaundice from 2000 to the present day. Two investigators independently selected the studies according to the inclusion and exclusion criteria, extracted the data, and assessed the quality of the selected studies. Meta-analysis was performed to compare postoperative morbidity and mortality of patients between the drainage and nondrainage groups.Compared with the nondrainage group, the overall mortality, overall morbidity, infectious morbidity, incidence of wound infection, intra-abdominal abscess, pancreatic fistulas, bile leak, and delayed gastric emptying in the drainage group were not significantly different. Compared with the nondrainage group, the drainage group had a drainage time of <4 weeks with an increased overall morbidity by 7% to 23%; however, the overall morbidity of the drainage group with a drainage time >4 weeks was not significantly different. Compared with the nondrainage group, the overall mortality of the drainage group using metal stents and plastic stents as internal drainage devices was reduced by 0.5% to 6%, whereas that of the drainage group using plastic stent devices was not significantly different.In summary, preoperative drainage should be applied selectively. The drainage time should be >4 weeks, and metal stents should be used for internal drainage.

Abstract
Pancreatic cancer is the fourth leading cause of cancer death in the United States. While surgical resection remains the only curative option, more than 80% of patients present with unresectable disease. Unfortunately, even among those who undergo resection, the reported median survival is 15-23 mo, with a 5-year survival of approximately 20%. Disappointingly, over the past several decades, despite improvements in diagnostic imaging, surgical technique and chemotherapeutic options, only modest improvements in survival have been realized. Nevertheless, it remains clear that surgical resection is a prerequisite for achieving long-term survival and cure. There is now emerging consensus that a subgroup of patients, previously considered poor candidates for resection because of the relationship of their primary tumor to surrounding vasculature, may benefit from resection, particularly when preceded by neoadjuvant therapy. This stage of disease, termed borderline resectable pancreatic cancer, has become of increasing interest and is now the focus of a multi-institutional clinical trial. Here we outline the history, progress, current treatment recommendations, and future directions for research in borderline resectable pancreatic cancer.

Abstract
A total of 77% of pancreatic head cancers manifest with obstructive jaundice. Hyperbilirubinemia impairs immunity and nutrition and is responsible for systemic toxicity. Several studies have attempted to investigate the impact of biliary drainage prior to duodenopancreatectomy (preoperative biliary drainage [PBD]) on jaundice resolution, morbidity, mortality and infectious complications, conferring high controversy. One large randomized controlled trial concluded that PBD should not be recommended in patients with distal obstructive jaundice owing to high infection rates. However, this work has been extensively criticized due to the exclusion of severely jaundiced patients, lack of information regarding antimicrobial agents used and employment of plastic instead of metal stents. However, proponents of PBD favor its application in selected cases. This work aims to review the literature on PBD for jaundice due to pancreatic head malignancy, to outline the controversy pertaining to this modality and to identify the indications of PBD in selected patients with malignant distal obstruction.

Abstract
Most patients with pancreatic cancer develop malignant biliary obstruction. Treatment of obstruction is generally indicated to relieve symptoms and improve morbidity and mortality. First-line therapy consists of endoscopic biliary stent placement. Recent data comparing plastic stents to self-expanding metallic stents (SEMS) has shown improved patency with SEMS. The decision of whether to treat obstruction and the means for doing so depends on the clinical scenario. For patients with resectable disease, preoperative biliary decompression is only indicated when surgery will be delayed or complications of jaundice exist. For patients with locally advanced disease, self-expanding metal stents are superior to plastic stents for long-term patency. For patients with advanced disease, the choice of metallic or plastic stent depends on life expectancy. When endoscopic stent placement fails, percutaneous or surgical treatments are appropriate. Endoscopic therapy or surgical approach can be used to treat concomitant duodenal and biliary obstruction.

Abstract
BACKGROUND Surgery on patients with malignant obstructive jaundice carries increased risks of postoperative morbidity and mortality. Preoperative biliary drainage has been developed to reduce this procedure-related risks, but its role in patients who are going to receive pancreaticoduodenectomy for periampullary carcinoma is still controversial. METHODS This article aimed at reviewing the current status of preoperative biliary drainage for patients with peri-ampullary tumors who were candidates for pancreaticoduodenectomy. A MEDLINE and PubMed database search from 1980 to 2013 was performed to identify relevant articles using the keywords "pancreaticoduodenectomy", "preoperative biliary drainage", "jaundice", "peri-ampullary neoplasm" and "carcinoma of pancreas". Additional papers were identified by a manual search of the references from the key articles. RESULTS There were six randomized controlled trials (RCTs) and 5 meta-analyses on preoperative biliary drainage for patients with malignant obstructive jaundice. Most of the results of these studies could not be used to define the role of preoperative biliary drainage for patients who received pancreaticoduodenectomy for periampullary carcinoma because: first, the majority of these studies were on bypass or palliative resections; second, various pathologies with both proximal and distal biliary obstruction were included; third, there were different forms of percutaneous or endoscopic drainage procedures; fourth, there were different durations of preoperative drainage; and finally, there were variations in the definition of events and outcomes. There was only one RCT which included a homogeneous group of patients with carcinoma of pancreas who underwent pancreaticoduodenectomy. For patients with periampullary tumor, the RCTS and meta-analyses showed no benefit of preoperative biliary drainage. Instead, there were some concerns about the drainage-related complications and the increase in positive intraoperative bile culture rate and the associated infective complication rate postoperatively. CONCLUSION Routine preoperative biliary drainage showed no beneficial effect on the surgical outcome for patients with periampullary tumor. A selective approach of preoperative biliary drainage should be adopted for these patients. The optimal duration and modality of preoperative biliary drainage remain unclear.

Abstract
OBJECTIVES Controversy exists regarding whether to place a plastic or a metal endobiliary stent in patients with resectable pancreatic cancer who require biliary drainage. Although self-expandable metal stents (SEMS) provide better drainage compared with plastic stents, concerns remain that SEMS may compromise resection and increase postoperative complications. Our objective was to compare surgical outcomes of patients undergoing pancreaticoduodenectomy (PD) with SEMS in place vs. plastic endoscopic stents (PES) and no stents (NS). METHODS We performed a retrospective analysis from a prospective database of all patients undergoing either attempted or successful PD with SEMS, PES, or NS in place at the time of operation. Patients were compared with regard to perioperative complications, margin status, and the rate of intraoperative determination of unresectability. RESULTS A total of 593 patients underwent attempted PD. Of these, 84 patients were locally unresectable intraoperatively and 509 underwent successful PD, of which 71 had SEMS, 149 had PES, and 289 had NS. Among patients who had a preoperative stent, SEMS did not increase overall or serious postoperative complications, 30-day mortality, length of stay, biliary anastomotic leak, or positive margin, but was associated with more wound infections and longer operative times. In those with adenocarcinoma, intraoperative determination of local unresectability was similar in the SEMS group compared with other groups, with 16 (19.3%) in SEMS compared with 29 (17.7%) in PES (P=0.862), and 31 (17.5%) in NS (P=0.732). CONCLUSIONS Placement of SEMS is not contraindicated in patients with resectable pancreatic cancer who require preoperative biliary drainage.

Abstract
BACKGROUND AND AIM Obstructive jaundice caused by distal biliary obstruction can present in up to 70 % of patients with localized cancer of the head of the pancreas. The aim of this study was to report our experience in using self-expanding metal stents (SEMS) for preoperative biliary decompression in patients with resectable and borderline resectable carcinoma of the pancreatic head. METHODS We performed a retrospective study evaluating patients from two tertiary referral centers. Two-hundred and forty-one patients with resectable and borderline resectable pancreatic carcinoma underwent ERCP with metal biliary stent placement between September 2006 and August 2011. We assessed the effectiveness of SEMS to adequately decompress the biliary tree, procedural success, patient survival, stent patency, and stent-related complications. RESULTS Two-hundred and forty-one patients were evaluated [123 male, mean age (± SD) 67.4 ± 9.8 years; resectable 174, borderline resectable 67]. Patients with borderline-resectable cancer underwent neoadjuvant therapy and restaging before possible curative surgery. Successful placement of a metal biliary stent was achieved in all patients and improved jaundice. Patients were followed for mean duration of 6.3 months. The overall survival was 49 % at 27 months. Fourteen (5.8 %) patients experienced stent occlusion; the mean time to stent occlusion was 6.6 (range 1-20) months. Immediate complications included: post-ERCP pancreatitis (n = 14), stent migration (n = 3), and duodenal perforation (n = 3). Long-term complications included stent migration (n = 9) and hepatic abscess (n = 1). A total of 144/174 patients deemed to have resectable cancer at time of diagnosis underwent curative surgery. Due to disease progression or the discovery of metastasis after neoadjuvant therapy, only 22/67 patients with borderline-resectable cancer underwent curative surgery. CONCLUSIONS SEMS should be considered for patients with obstructive jaundice and resectable or borderline resectable pancreatic cancer, especially if surgery is not planned immediately as a result of preoperative chemoradiation. These stents appear to be safe and effective.

Abstract
BACKGROUND Neoadjuvant therapy is increasingly utilized for pancreatic cancer patients to decrease tumor burden in anticipation of later surgical resection. However, infectious complications such as life threatening cholangitis may occur for those with biliary obstruction. We hypothesized that placement of metal rather than plastic stents in such patients results in lower rates of stent-related complications, leading to improved clinical outcomes. METHODS Retrospective cohort of pancreatic cancer patients treated by the University of Michigan Multidisciplinary Pancreatic Cancer Destination Program between January 2005 and June 2010. Only patients undergoing neoadjuvant therapy with one or more biliary stents placed for malignant obstruction were studied. Time to stent complication was compared between metal and plastic stents. The complication rate was estimated as the ratio of complications to total stent exposure time and 95% confidence intervals were calculated. RESULTS 52 patients met inclusion criteria. A total of 113 stents were placed in 52 patients (70 plastic, 43 metal). The complication rate was almost 7 times higher with plastic stents, 0.20 (95% CI, 0.14-0.30), than with metal stents, 0.03 (95% CI, 0.01-0.06). Moreover, the rate of hospitalization for stent-related complications was 3-fold higher in the plastic stent group than the metal stent group. The first quartile estimate of time to stent complication was almost 5 times longer for metal than for plastic stents (44 vs. 200 days) (P<0.0001). CONCLUSION Compelling evidence indicates that self-expanding metal, not plastic stents should be used for malignant biliary obstruction in patients undergoing neoadjuvant therapy for pancreatic cancer.

Abstract
Endoscopy has an increasingly important role in the palliation of patients with pancreatic ductal adenocarcinoma. Endoscopic biliary drainage is still requested in the majority of patients who present with obstructive jaundice, and the increased use of self-expandable metallic stents has reduced the incidence of premature stent occlusion. First-line use of metallic stents is expected to be utilized more frequently as neoadjuvant protocols are improved. The efficacy of endoscopy for palliating gastroduodenal obstruction has advanced with the development of through-the-scope, self-expandable gastroduodenal stents. There have been advances in pain management, with endoscopic ultrasound-guided celiac plexus neurolysis reducing opiate requirements and pain for patients with unresectable malignancy. Future applications of endoscopy in pancreatic cancer may include fine-needle injection of chemotherapeutic and other agents into the lesion itself. This review will summarize the evidence of endoscopy in the management of patients with pancreatic cancer.
