Abstract
OBJECTIVE Assessing unclear biliary strictures is challenging. We analyzed the diagnostic performance of radiology, EUS, and ERCP. METHODS All patients referred for EUS and ERCP to assess an unclear biliary stricture were prospectively included. The data from radiology, EUS, ERCP, and tissue sampling were recorded. The diagnostic modalities were analyzed separately and in combination, with a focus on PSC. RESULTS Between 2013 and 2020, 78 patients were included; 31% had PSC. A cholangioscopy was not performed in this study. The final diagnosis indicated that the biliary stricture was benign in 62% of the patients and malignant in 38%. The differences among the modalities were numerical, not significant. The modalities showed an accuracy between 78 and 83% in all the patients and between 75 and 83% in the patients with PSC. The combination of radiology and EUS showed the highest sensitivity of 94% in all the patients and a sensitivity of 100% in PSC. Tissue sampling showed the highest specificity of 93% in all patients and 89% in PSC. In 22 cases with combined EUS, ERCP, and tissue sampling, the accuracy, sensitivity, and specificity were 82%, 70%, and 92%, respectively. Minor differences were observed between the intention-to-diagnose analysis and the per-protocol analysis. Adverse events were recorded in 4% of cases. CONCLUSION The combination of EUS and ERCP with tissue sampling seems to be useful and safe for excluding malignancy in unclear biliary strictures. In cases with a reduced suspicion of malignancy, radiology with an EUS may be sufficient.

Gallbladder cancer mimicking perihilar cholangiocarcinoma-considerable rate of postoperative reclassification with implications for prognosis. World J Surg Oncol 2023; 21:286. [PMID: 37697321 PMCID: PMC10494342 DOI: 10.1186/s12957-023-03171-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Accepted: 09/07/2023] [Indexed: 09/13/2023] Open
Abstract
BACKGROUND For some patients undergoing resection under the suspicion of a perihilar cholangiocarcinoma (pCCA), postoperative diagnosis may differ from the preoperative diagnosis. While a postoperative finding of benign bile duct stricture is known to affect 3-15% of patients, less has been described about the consequences of finding other biliary tract cancers postoperatively. This study compared pre- and postoperative diagnoses, risk characteristics, and outcomes after surgery for suspected pCCA. METHODS Retrospective single-center study, Karolinska University Hospital, Stockholm, Sweden (January 2009-May 2017). The primary postoperative outcome was overall survival. Secondary outcomes were disease-free survival and postoperative complications. Survival analysis was performed by the Kaplan-Meier method. RESULTS Seventy-one patients underwent resection for suspected pCCA. pCCA was confirmed in 48 patients (68%). Ten patients had benign lesions (14%), 2 (3%) were diagnosed with other types of cholangiocarcinoma (CCA, distal n = 1, intrahepatic n = 1), while 11 (15%) were diagnosed with gallbladder cancer (GBC). GBC patients were older than patients with pCCA (median age 71 versus 58 years, p = 0.015), with a large proportion of patients with a high tumor extension stage (≥ T3, 91%). Median overall survival was 20 months (95% CI 15-25 months) for patients with pCCA and 17 months (95% CI 11-23 months) for patients with GBC (p = 0.135). Patients with GBC had significantly shorter median disease-free survival (DFS), 10 months (95% CI 3-17 months) compared 17 months (95% CI 15-19 months) for patients with pCCA (p = 0.010). CONCLUSIONS At a large tertiary referral center, 15% of patients resected for suspected pCCA were postoperatively diagnosed with GBC. Compared to patients with pCCA, GBC patients were older, with advanced tumors and shorter DFS. The considerable rate of re-classification stresses the need for improved preoperative staging, as these prognostic differences could have implications for treatment strategies.

Fluorescence In Situ Hybridization in Primary Diagnosis of Biliary Strictures: A Single-Center Prospective Interventional Study. Biomedicines 2023; 11:biomedicines11030755. [PMID: 36979734 PMCID: PMC10045065 DOI: 10.3390/biomedicines11030755] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 02/22/2023] [Accepted: 02/24/2023] [Indexed: 03/06/2023] Open
Abstract
Background and aims: Diagnosis of the biliary stricture remains a challenge. In view of the low sensitivity of brush cytology (BC), fluorescence in situ hybridization (FISH) has been reported as a useful adjunctive test in patients with biliary strictures. We aimed to determine performance characteristics of BC and FISH individually and in combination (BC + FISH) in the primary diagnosis of biliary strictures. Methods: This single-center prospective study was conducted between April 2019 and January 2021. Consecutive patients with unsampled biliary strictures undergoing first endoscopic retrograde cholangiopancreatography in our institution were included. Tissue specimens from two standardized transpapillary brushings from the strictures were examined by routine cytology and FISH. Histopathological confirmation after surgery or 12-month follow-up was regarded as the reference standard for final diagnosis. Results: Of 109 enrolled patients, six were excluded and one lost from the final analysis. In the remaining 102 patients (60.8% males, mean age 67.4, range 25–92 years), the proportions of benign and malignant strictures were 28 (27.5%) and 74 (72.5%), respectively. The proportions of proximal and distal strictures were 26 (25.5%) and 76 (74.5%), respectively. In comparison to BC alone, FISH increased the sensitivity from 36.1% to 50.7% (p = 0.076) while maintaining similar specificity (p = 0.311). Conclusions: Dual-modality tissue evaluation using BC + FISH showed an improving trend in sensitivity for the primary diagnosis of biliary strictures when compared with BC alone.

Abstract
Background and aim Indeterminate biliary stricture (IBS) is a frequently encountered clinical problem. In this study, we aimed to highlight the clinical characteristics, risk factors and diagnostic outcomes of patients presented with indeterminate biliary stricture. Method A Retrospective multicenter study included all patients diagnosed with IBS in the participating centers between 2017 and 2021. Data regarding IBS such as presentations, patient characteristics, diagnostic and therapeutic modalities were collected from the patients' records and then were analyzed. Results Data of 315 patients with IBS were retrospectively collected from 7 medical centers with mean age: 62.6 ± 11 years, females: 40.3% and smokers: 44.8%. For diagnosing stricture; Magnetic resonance imaging/Magnetic resonance cholangiopancreatography (MRI/MRCP) was the most frequently requested imaging modality in all patients, Contrast enhanced computerized tomography (CECT) in 85% and endoscopic ultrasound (EUS) in 23.8%. Tissue diagnosis of cholangiocarcinoma was achieved in 14% only. The used therapeutic modalities were endoscopic retrograde cholangiopancreatography (ERCP)/stenting in 70.5%, percutaneous trans-hepatic biliary drainage (PTD): 17.8%, EUS guided drainage: 0.3%, and surgical resection in 8%. The most frequent type of strictures was distal stricture in 181 patients, perihilar in 128 and intrahepatic in 6. Distal strictures had significant male predominance, with higher role for EUS for diagnosis and higher role for ERCP/stenting for drainage, while in the perihilar strictures, there was higher role for CECT and MRI/MRCP for diagnosis and more frequent use of PTD for drainage. Conclusion Indeterminate biliary stricture is a challenging clinical problem with lack of tissue diagnosis in most of cases mandates an urgent consensus diagnostic and treatment guidelines.

Cytological Comparison between Hepatocellular Carcinoma and Intrahepatic Cholangiocarcinoma by Image Analysis Software Using Touch Smear Samples of Surgically Resected Specimens. Cancers (Basel) 2022; 14:cancers14092301. [PMID: 35565430 PMCID: PMC9102894 DOI: 10.3390/cancers14092301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 05/01/2022] [Accepted: 05/04/2022] [Indexed: 02/05/2023] Open
Abstract
To investigate useful cytological features for differential diagnosis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC), this study cytologically compared HCC to ICC using image analysis software. Touch smear specimens of surgically resected specimens were obtained from a total of 61 nodules of HCC and 16 of ICC. The results indicated that the major/minor axis ratio of ICC is significantly larger than that of HCC (1.67 ± 0.27 vs. 1.32 ± 0.11, p < 0.0001) in Papanicolaou staining. This result means that the nucleus of HCC is close to round and the nucleus of ICC is close to an oval. This significant difference in the major/minor axis ratio between ICC and HCC was consistently observed by the same analyses using clinical samples of cytology (4 cases of HCC and 13 cases of ICC) such a fine-needle aspiration, brushing and ascites (ICC: 1.45 ± 0.13 vs. HCC: 1.18 ± 0.056, p = 0.004). We also confirmed that nuclear position center-positioned nucleus (p < 0.0001) and granular cytoplasm (p < 0.0001) are typical features of HCC tumor cells compared to ICC tumor cells. The research study found a significant difference in the nuclear morphology of HCC (round shape) and ICC (oval shape) in Papanicolaou-stained cytology specimens. This simple and objective finding will be very useful for the differential cytodiagnosis of HCC and ICC.

Abstract
Probe-based confocal laser endomicroscopy (pCLE), also known as optical biopsy, is a new endoscopic technique that provides real-time magnification of 1000 × microscopic tissue information to diagnose indeterminate biliary strictures. Tissue sampling by endoscopic retrograde cholangiopancreatography (ERCP) is routinely performed to evaluate indeterminate biliary strictures. To evaluate the accuracy of pCLE and tissue sampling by ERCP in the diagnosis of indeterminate biliary strictures, 18 articles were included from 2008 to 2021 through Embase, PubMed, Web of Science, and Cochrane library databases. The summary estimates for the pCLE diagnosis of indeterminate biliary strictures were: sensitivity 0.88 (95% confidence interval (CI), 0.84-0.91); specificity 0.79 (95% CI 0.74-0.83); and Diagnostic Odds Ratio (DOR) 24.63 (95% CI 15.76-38.48). The summary estimates for tissue sampling by ERCP diagnosis for indeterminate biliary strictures were: sensitivity 0.54 (95% CI 0.49-0.59); specificity 0.96 (95% CI 0.94-0.98); and DOR 11.31 (95% CI 3.90-32.82). The area under the sROC curve of pCLE diagnosis of indeterminate biliary strictures is 0.90 higher than 0.65 of tissue sampling by ERCP. The pCLE is a better approach than tissue sampling by ERCP for the diagnosis of indeterminate biliary strictures by providing real-time microscopic images of the bile ducts.

Abstract
BACKGROUND AND AIM Transpapillary biliary forceps biopsy (TBFB) is a common method to obtain histological evidence for the differential diagnosis of biliary stricture. This study aimed to evaluate the factors associated with a positive cancer diagnosis from TBFB and the number of tissue samples required to increase the diagnostic yield in patients with malignant biliary strictures. METHODS A total of 376 patients who underwent TBFB for investigation of biliary stricture were included. Factors affecting the diagnostic yield of TBFB were determined using univariate analysis and multivariate logistic regression analyses. RESULTS Bile duct cancer (odds ratio [OR] = 3.50, P = 0.002), intraductal growing type (OR = 9.01, P = 0.001), and number of tissue samples (n < 5 vs 5 ≤ n < 10, OR = 4.13, P = 0.01; n < 5 vs n ≥ 10, OR = 12.25, P < 0.001; 5 ≤ n < 10 vs n ≥ 10, OR = 2.97, P = 0.046) were significant factors associated with positive results for malignancy. In patients with periductal infiltrating-type bile duct cancer, the number of tissue samples was a significant factor for diagnostic sensitivity (54.3% in the n < 5 group, 83.3% in the 5 ≤ n < 10 group and 98.2% in the n ≥ 10 group) (P < 0.001). CONCLUSIONS Bile duct cancer, intraductal growing type, and five or more tissue samples were significant predictors of positive TBFB results in patients with malignant biliary stricture. Increasing the number of tissue samples by five or more led to higher sensitivity in bile duct cancer patients with the periductal infiltrating type.

Abstract
Background: Peroral cholangioscopy (POCS) has become a widely-used technique in diagnosing indeterminate biliary strictures, enabling optical viewing of the biliary system and targeted biopsies under direct vision. The diagnostic utility of the new endoscopic scraper, Trefle®, for extrahepatic cholangiocarcinoma (ECC) has also been reported. However, the diagnostic utility of POCS-guided and Trefle®-assisted tissue acquisition for ECC has never been compared empirically. We evaluated the efficacy and safety of Trefle®-assisted tissue acquisition for diagnosing ECC compared with POCS-guided tissue sampling. Methods: Patients who underwent Trefle®-assisted tissue acquisition or POCS-guided forceps biopsy to differentiate ECC from benign biliary disease between April 2014 and March 2018 were enrolled retrospectively. We evaluated the diagnostic performance of Trefle®-assisted tissue acquisition and POCS-guided forceps biopsy based on pathological evaluation. We also compared adverse events associated with Trefle®-assisted tissue acquisition with those of POCS-guided forceps biopsy. Results: We enrolled 34 patients with biliary disease and performed Trefle®-assisted tissue acquisition and POCS-guided forceps biopsy in 14 and 20 patients, respectively. Sensitivity, specificity, and accuracy of Trefle®-assisted tissue acquisition were 87.5%, 83.3%, and 85.7%, respectively, and for POCS-guided forceps biopsy, these were 90.0% each. Statistical values of Trefle®-assisted tissue acquisition and POCS-guided tissue acquisition were not significantly different. There were no significant differences in the occurrence of adverse events between the Trefle®-assisted tissue acquisition and the POCS-guided forceps biopsy (35.7% vs. 25.0%, p = 0.770). Compared with patients who underwent POCS procedure, endoscopic sphincterotomy was performed for fewer patients who underwent Trefle®-assisted tissue acquisition (p < 0.001). Conclusions: The diagnostic ability of Trefle®-assisted tissue acquisition for ECC is similar to that of POCS-guided tissue acquisition. Trefle®-assisted tissue acquisition might also help to preserve the sphincter of Oddi and its digestive function.

Abstract
Few studies have compared the diagnostic utility of endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) and endoscopic retrograde cholangiopancreatography (ERCP) tissue sampling for extrahepatic cholangiocarcinoma (ECC). We evaluated the efficacy and safety of EUS-FNA for diagnosing ECC compared with ERCP tissue sampling. Patients who underwent EUS-FNA or ERCP tissue sampling to differentiate ECC from benign biliary disease were enrolled retrospectively between October 2011 and March 2017. We evaluated diagnostic performances of EUS-FNA and ERCP tissue sampling based on pathological evaluation. We compared adverse events in EUS-FNA and ERCP tissue sampling. We enrolled 73 patients with biliary disease and performed EUS-FNA and ERCP in 19 and 54 patients, respectively. Sensitivity, specificity, and accuracy of ERCP tissue sampling were 76.0%, 100%, and 88.9%, respectively, and for EUS-FNA these were 81.8%, 87.5%, and 84.2%, respectively. Statistical values of ERCP tissue sampling and EUS-FNA were not significantly different. The adverse event frequency of EUS-FNA was significantly lower than that of ERCP tissue sampling (0% vs. 25.9%, p = 0.033). The diagnostic ability of EUS-FNA for ECC is similar to that of ERCP tissue sampling. EUS-FNA is a safer tissue sampling modality than ERCP for evaluating biliary disease.

Behary J, Keegan M, Craig PI. The interobserver agreement of optical features used to differentiate benign from neoplastic biliary lesions assessed at balloon-assisted cholangioscopy. J Gastroenterol Hepatol 2019; 34:595-602. [PMID: 30499127 DOI: 10.1111/jgh.14556] [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: 08/27/2018] [Revised: 11/12/2018] [Accepted: 11/17/2018] [Indexed: 12/20/2022]
Abstract
BACKGROUND AND AIM Balloon-assisted cholangioscopy allows mucosal assessment of the biliary tree with pediatric endoscopes. No validated optical criteria exist to differentiate benign from neoplastic biliary lesions. We aimed to identify, validate, and revalidate optical features differentiating benign from neoplastic biliary lesions. Furthermore, we aimed to determine whether cholangioscopic appearance allows endoscopists to accurately differentiate benign from neoplastic biliary lesions. METHODS Baseline: from 44 de-identified balloon-assisted cholangioscopy videos, a blinded investigator analyzed potential optical features distinguishing benign from neoplastic biliary lesions. VALIDATION during the initial "teaching phase," 20 endoscopists viewed video clips of 11 optical features identified in the baseline study. At the subsequent "test phase," 20 further video clips were assessed by the endoscopists blinded to clinical details and questionnaires completed for the presence or absence of optical features, favored diagnosis and diagnostic confidence. Revalidation: The six identified optical features from the validation study with at least moderate agreement were revalidated the same way 12 months later assessing 20 new lesions. RESULTS Baseline: 11 optical features were found to differentiate benign from neoplastic biliary lesions. Validation and revalidation: six optical features demonstrated at least moderate interobserver agreement (irregular margin, dark mucosa, adherent mucous, papillary projections, tubular, or branched/disorganized surface structures). Endoscopists correctly diagnosed lesions as benign in 89% and neoplastic in 83%. When highly confident, endoscopists correctly diagnosed 96% of benign and 87% neoplastic lesions. CONCLUSIONS Six features were validated and revalidated to differentiate benign from neoplastic biliary lesions. When highly confident with a diagnosis, endoscopists usually differentiate benign from neoplastic biliary lesions.

Abstract
Background/Aims Pathological diagnosis of biliary strictures with atypical or suspicious cells on endoscopic retrograde brush cytology and indeterminate strictures on imaging is challenging. The aim of this study was to identify markers for malignant strictures in such cases.
Methods We retrospectively analyzed data collected from 146 consecutive patients with indeterminate biliary strictures on imaging who underwent endoscopic retrograde brush cytology from 2007 to 2013. Factors associated with malignant strictures in patients with atypical or suspicious cells on brush cytology were identified.
Results Among the 67 patients with a malignant disease (48 cholangiocarcinoma, 6 gallbladder cancer, 5 pancreatic cancer, 5 ampulla of Vater cancer, and 3 other types), 36 (53.7%) had atypical or suspicious cells on brush cytology. Among these, the factors that independently correlated with malignant strictures were stricture length (odds ratio [OR], 5.259; 95% confidence interval [CI], 1.802– 15.294) and elevated carbohydrate antigen 19-9 (CA19-9) (OR, 3.492; 95% CI, 1.242–9.815), carcinoembryonic antigen (CEA) (OR, 4.909; 95% CI, 1.694–14.224), alkaline phosphatase (ALP) (OR, 3.362; 95% CI, 1.207–9.361), and gamma-glutamyl transpeptidase (rGT) (OR, 4.318; 95% CI, 1.512–12.262).
Conclusions Elevated levels of CA19-9, CEA, ALP, and rGT and stricture length are associated with malignant strictures in patients with indeterminate biliary strictures on imaging and atypical or suspicious cells on brush cytology.

Abstract
Primary sclerosing cholangitis (PSC) is a rare but clinically important cholestatic liver disease. Histopathologically and cholangiographically, PSC is characterized by intra- and/or extra-hepatic bile duct inflammation and fibro-obliteration, which ultimately leads to biliary cirrhosis and related sequelae, including development of hepatobiliary and colorectal carcinomata. PSC can be diagnosed at essentially any age and carries a median survival of 15-20 years, regardless of age at diagnosis, and is a foremost risk factor for cholangiocarcinoma. Given the chronic and progressive nature of PSC, its inherent association with both neoplastic and non-neoplastic biliary tract complications, and the lack of effective pharmacotherapies, alimentary and biliary tract endoscopy plays a major role in the care of patients with PSC. Areas covered: Here, we provide a narrative review on endoscopic management of PSC, including established and evolving applications to the diagnosis and treatment of both its benign and malignant complications. Expert commentary: Due to the rarity of PSC and the considerable patient-years required to rigorously study major endpoints, there remains a paucity of high-quality evidence regarding its management. As the advanced endoscopic repertoire expands, so has the interest in developing best practices in PSC, which we discuss herein.

Abstract
BACKGROUND Pre-operative tissue diagnosis for suspected malignant biliary strictures remains challenging. AIM To develop evidence-based consensus statements on endoscopic tissue acquisition for biliary strictures. METHODS The initial draft of statements was prepared following a systematic literature review. A committee of 20 experts from Asia-Pacific region then reviewed, discussed, and modified the statements. Two rounds of independent voting were conducted to reach a final version. Consensus was considered to be achieved when 80% or more of voting members voted "agree completely" or "agree with some reservation." RESULTS Eleven statements achieved consensus. The choice of tissue sampling modalities for biliary strictures depends on the clinical setting, the location of lesion, and availability of expertise. Detailed radiological and endoscopic evaluation is useful to guide the selection of appropriate tissue acquisition technique. Standard intraductal biliary brushing and/or forceps biopsy is the first option when endoscopic biliary drainage is required with an overall (range) sensitivity and specificity of 45% (26%-72%) and 99% (98%-100%), and 48% (15%-100%) and 99% (97%-100%), respectively, in diagnosing malignant biliary strictures. Probe-based confocal laser endomicroscopy and fluorescence in situ hybridisation using 4 fluorescent-labelled probes targeting chromosomes 3, 7, 17 and 9p21 locus may be added to improve the diagnostic yield. Cholangioscopy-guided biopsy and EUS-guided tissue acquisition can be considered after prior negative conventional tissue sampling with an overall (range) sensitivity and specificity of 60% (38%-88%) and 98% (83%-100%), and 80% (46%-100%) and 97% (92%-100%), respectively, in diagnosing malignant biliary strictures. CONCLUSION These consensus statements provide evidence-based recommendations for endoscopic tissue acquisition of biliary strictures.

Abstract
BACKGROUND Distinguishing perihilar cholangiocarcinoma (PHC) from benign forms of sclerosing cholangitis affecting the hilar bile ducts is challenging, since histological confirmation of PHC is difficult to obtain and accurate non-invasive diagnostic tests are not available. IgG4-associated cholangitis (IAC), an imitator of PHC, may present with clinical and radiographical signs of PHC. IAC can be accurately diagnosed with a novel qPCR test. The aim of this study was to investigate the incidence and long-term activity of IAC in patients resected for PHC in a single tertiary center over a period of 30 years. METHODS All patients with benign disease who underwent surgery for presumed PHC in our institute between 1984 and 2015 were identified. Benign liver and bile duct specimens were re-evaluated by a pathologist and scored according to international consensus pathology criteria for IgG4-related disease (IgG4-RD). Patients with benign disease still alive were followed-up and a clinical diagnosis of IAC was made using a combination of the HISORt group C (response to steroids) criteria and elevated serum IgG4 levels and/or the novel IgG4/IgG RNA ratio. Also, recurrent symptomatic disease at any time after surgery requiring immunosuppression was assessed. RESULTS Out of 323 patients who underwent surgery for presumed PHC, 50 patients (15%) had benign disease. In 42% (n = 21/50) of these patients a histological (n = 17) or clinical (n = 4) diagnosis of IAC was established. The remaining patients were diagnosed with unclassified sclerosing inflammation, cystadenoma, or sclerosing hemangioma. Nine out of 12 IAC patients who were followed-up showed episodes of recurrent disease requiring immunosuppressive treatment. CONCLUSIONS Liver and bile duct resections for PHC during three decades disclosed in 15% benign biliary disorders mimicking PHC of which 42% were definitely diagnosed as IAC. IgG4-RD remains active in the majority of patients with IAC years after surgery. Novel diagnostic tests for IAC might reduce misdiagnosis, unnecessary surgery, and life-threatening complications.

Abstract
AIM Perihilar cholangiocarcinoma (PHC) is a challenging disease and requires aggressive surgical treatment in order to achieve curation. The assessment and work-up of patients with presumed PHC is multidisciplinary, complex and requires extensive experience. The aim of this paper is to review current aspects of diagnosis, preoperative work-up and extended resection in patients with PHC from the perspective of our own institutional experience with this complex tumor. METHODS We provided a review of applied modalities in the diagnosis and work-up of PHC according to current literature. All patients with presumed PHC in our center between 2000 and 2016 were identified and described. The types of resection, surgical techniques and outcomes were analyzed. RESULTS AND CONCLUSION Upcoming diagnostic modalities such as Spyglass and combinations of serum biomarkers and molecular markers have potential to decrease the rate of misdiagnosis of benign, inflammatory disease. Assessment of liver function with hepatobiliary scintigraphy provides better information on the future remnant liver (FRL) than volume alone. The selective use of staging laparoscopy is advisable to avoid futile laparotomies. In patients requiring extended resection, selective preoperative biliary drainage is mandatory in cholangitis and when FRL is small (< 50%). Preoperative portal vein embolization (PVE) is used when FRL volume is less than 40% and optionally includes the left portal vein branches to segment 4. Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) as alternative to PVE is not recommended in PHC. N2 positive lymph nodes preclude long-term survival. The benefit of unconditional en bloc resection of the portal vein bifurcation is uncertain. Along these lines, an aggressive surgical approach encompassing extended liver resection including segment 1, regional lymphadenectomy and conditional portal venous resection translates into favorable long-term survival.

Abstract
Background and Aims: There are no systematic reviews comparing the use of endoscopic retrograde cholangiopancreatography (ERCP)-based brush cytology and forceps biopsy and endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) for the diagnosis of malignant biliary stricture; so in this revision, we will compare ERCP against EUS-FNA for tissue diagnosis of malignant biliary stricture. Design: A systematic review was conducted of comparative studies (prospective or retrospective) analyzing EUS and ERCP for tissue diagnosis of malignant biliary stricture. Materials and Methods: The databases Medline, EMBASE, Cochrane, LILACS, CINAHL, and Scopus were searched for studies dated previous to November 2014. We identified three prospective studies comparing EUS-FNA and ERCP for the diagnosis of malignant biliary stricture and five prospective studies comparing EUS-FNA with the same diagnosis of the other three studies. All patients were subjected to the same gold standard method. We calculated study variables (sensitivity, specificity, prevalence, positive and negative predictive values, and accuracy) and performed a meta-analysis using the Review Manager (RevMan) 5.3 software. Results: A total of 294 patients were included in the analysis. The pretest probability for malignant biliary stricture was 76.66%. The mean sensitivities of ERCP and EUS-FNA for tissue diagnosis of malignant biliary stricture were 49% and 75%, respectively; the specificities were 96.33% and 100%, respectively. The posttest probabilities positive predictive value (98.33% and 100%, respectively) and negative predictive value (34% and 47%, respectively) were determined. The accuracies were 60.66% and 79%, respectively. Conclusion: We found that EUS-FNA was superior to ERCP with brush cytology and forceps biopsy for diagnosing malignant biliary strictures. However, a negative EUS-FNA or ERCP test may not exclude malignant biliary stricture because both have low negative posttest probabilities.

Abstract
Klatskin's tumors, actually-redefined as perihilar cholangiocarcinoma (phCCA) do represent 50-70% of all CCAs and develop in a context of chronic inflammation and cholestasis of bile ducts. Surgical resection provides the only chance of cure for this disease but is technically challenging because of the complex, intimate and variable relationship between biliary and vascular structures at this location. Five years survival rates range between 25-45% (median 27-58 months) in case of R0 resection and 0-23% (median 12-21 months) in case of R1 resection respectively. It should be noted that the major costs of high radicality are represented by relative high morbidity and mortality rates (i.e., 20-66% and 0-9% respectively). Considering the fact that radical resection may represent the only curative treatment of phCCA, we focused our review on surgical planning and techniques that may improve resectability rates and outcomes for locally advanced phCCA. The surgical treatment of phCCA can be successful when following aspects have been fulfilled: (I) accurate preoperative diagnostic aimed to identify the tumor in all its details (localization and extension) and to study all the risk factors influencing a posthepatectomy liver failure (PHLF): i.e., liver volume, liver function, liver quality, haemodynamics and patient characteristics; (II) High end surgical skills taking in consideration the local extension of the tumor and the vascular invasion which usually require an extended hepatic resection and often a vascular resection; (III) adequate postoperative management aimed to avoid major complications (i.e., PHLF and biliary complications). These are technically challenging operations and must be performed in a high volume centres by hepato-biliary-pancreas (HBP)-surgeons with experience in microsurgical vascular techniques.

Abstract
BACKGROUND AND STUDY AIMS For suspected pancreaticobiliary malignancies, endobiliary brush cytology during endoscopic retrograde cholangiopancreatography (ERCP) remains the diagnostic test of choice despite historically poor and variable sensitivity. This has led to increased use of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) as an initial test. Recently, our institution began using a cytology brush that was designed specifically to collect a more substantial and higher-quality sample. The aim of this study was to investigate whether this brush design would provide more adequate samples and have high agreement with EUS-FNA in patients who underwent both procedures. PATIENTS AND METHODS A retrospective chart review was conducted of all patients who underwent both EUS-FNA and endobiliary brush cytology for suspicion of pancreaticobiliary malignancy from January 2013 to May 2015. A total of 41 patients met the inclusion criteria. Initially, sample quality was evaluated. Final cytology results were then assessed for agreement with EUS-FNA using Cohen's kappa. The effect of considering atypical cytology as negative was also uniquely evaluated by running separate analyses. RESULTS Brush cytology provided an adequate sample in 95.1 % of cases. Cohen's Kappa demonstrated moderate agreement between brush cytology and EUS-FNA: κ = 0.42 ( P = 0.001). When atypical results were excluded, agreement increased: κ = 0.60 ( P = 0.02), but remained moderate. If atypical results were considered "positive," the two procedures demonstrated equal cancer detection rates of 80.8 %. CONCLUSIONS The studied brush provided more adequate samples compared with historical rates for brush cytology and had moderate agreement with EUS-FNA. If this brush truly increases sample adequacy, it could potentially provide results comparable to EUS-FNA at lower cost.

[PMID: 27142076 PMCID: PMC4855757 DOI: 10.1186/s12957-016-0883-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2015] [Accepted: 04/21/2016] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Tissue sampling for biliary stricture is important for differential diagnosis and further treatment. This study aims to assess the differences of transpapillary biliary biopsy for malignant biliary strictures between cholangiocarcinoma and pancreatic cancer. METHODS From January 2010 to December 2013, we retrospectively studied 79 patients who suffered from biliary strictures and received transpapillary forceps biopsy after sphincterotomy for tissue sampling. The diagnostic sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of forceps biopsy were calculated in all cases for both cholangiocarcinoma and pancreatic cancer patients. Possible factors that distinguish malignant strictures from benign strictures and which could affect the accuracy of tissue sampling were analyzed. RESULTS There are 65 malignant and 14 benign biliary stricture patients enrolled. The malignant group has a significantly higher serum bilirubin level than the benign group, but age, clinical presentation, level of serum carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19-9, and alkaline phosphatase are not. The sensitivity, specificity, PPV, and NPV of forceps biopsy for biliary stricture are 53.85, 100, 100, and 31.82%, respectively. The cholangiocarcinoma group has a higher sensitivity (73.53 versus 29.17%, p < 0.001), older age, lower CA 19-9 level, and more common hepatic duct strictures than the pancreatic group. The age, serum CEA, CA 19-9 and the alkaline phosphatase level, serum bilirubin level >10 mg/dL, tissue sampling ≧3 are not significant factors affecting diagnostic accuracy in forceps biopsy for pancreatobiliary strictures. There is neither major bleeding nor perforation in our study. CONCLUSIONS Transpapillary forceps biopsy of biliary strictures after sphincterotomy for tissue sampling is safe and a significantly higher sensitive method in cholangiocarcinoma but not in pancreatic cancer.

Abstract
PURPOSE To investigate (1) diagnostic performance of transabdominal color doppler ultrasound (US) and endoscopic ultrasound (EUS) for detection and sub-classification of common bile duct varices (CBDV) in patients with portal vein thrombosis (PVT), and (2) clinical significance and natural history of CBDV subtypes. PATIENTS AND METHODS During a 4-year period, 56 patients with PVT underwent US and EUS for the presence and subtypes of CBDV. Natural history was analyzed for patients who attended control visits. RESULTS CBDV were diagnosed in 57 and 59 % of patients with US and EUS, respectively. In 19 % of patients, EUS revealed different CBDV subtypes than previously seen by US. The most common were paracholedochal (PCV), while the least common were epicholedochal (ECV) and Submucosal varices (SMV). Nine patients had obstructive jaundice and underwent ERCP which was complicated by hemobilia in two patients with SMV. Among eight patients who underwent control EUS (median follow-up 60 months), the form of CBDV remained unchanged. Two patients bled from esophageal varices, both with ECV. CONCLUSION While abdominal US and EUS are equally sensitive for detection of CBDV, EUS allows more precise determination of CBDV subtype. Patients with SMV might be at increased risk of bleeding upon ERCP.

Abstract
Endoscopy has important roles in the management of primary sclerosing cholangitis (PSC), ranging from narrowing down the differential diagnoses, screening for complications, determining prognosis and therapy. While the need for a diagnostic endoscopic retrograde cholangiopancreatography (ERCP) may be obviated by a positive magnetic resonance cholangiopancreatography (MRCP), a negative MRCP does not exclude PSC and may therefore necessitate an ERCP, which is traditionally regarded as the gold standard. In this editorial we have not covered the endoscopic management of inflammatory bowel disease in the context of PSC nor of endoscopic surveillance and treatment of portal hypertension complicating PSC.

Abstract
Metastatic breast cancer is typically identified in the bones, lymph nodes, lungs and liver. Rarely does metastatic breast cancer involve the common bile duct (CBD) without direct extension from liver metastasis into the CBD. We present a woman diagnosed with metastatic breast cancer in the CBD after presenting with obstructive jaundice. Patients with a history of primary breast cancer who present with obstructive jaundice secondary to CBD mass need identification of the mass in order to provide appropriate treatment.

Abstract
BACKGROUND Differentiating between malignant and benign biliary lesions is critical in clinical practice but is difficult. OBJECTIVE To systematically evaluate the diagnostic performance of single-operator peroral cholangioscopy on indeterminate biliary lesions. DESIGN A systematic review and meta-analysis. PATIENTS Patients with indeterminate biliary lesions or equivocal ERCP findings. MAIN OUTCOME MEASUREMENTS The diagnostic performance of single-operator peroral cholangioscopy on indeterminate biliary lesions. The area under the summary receiver-operating characteristic curve was used as the main indicator for the overall diagnostic performance of single-operator peroral cholangioscopy visual impression (VI) and SpyBite biopsy (SB). The sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were also synthesized. RESULTS A total of 8 studies met the inclusion criteria, involving 335 patients who had data on VI and 337 who had data on SB. The area under the curve values on the summary receiver-operating characteristic curve of single-operator peroral cholangioscopy VI and SB were 0.94 (95% confidence interval [CI], 0.92-0.96) and 0.93 (95% CI, 0.90-0.95) respectively. The combined sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were 90% (95% CI, 73%-97%), 87% (95% CI, 76%-94%), 7.1 (95% CI, 3.8-13.3), 0.12 (95% CI, 0.04-0.33) for VI and 69% (95% CI, 57%-79%), 98% (95% CI, 92%-99%), 30.1 (95% CI, 8.5-106.9), and 0.32 (95% CI, 0.23-0.44) for SB, respectively. LIMITATIONS Small number of included studies; comparison with ERCP could not be made. CONCLUSION Single-operator peroral cholangioscopy is a good tool for differentiating malignant and benign biliary lesions. VI is useful for detecting malignant lesion, whereas SB is better at confirming a malignant diagnosis, but VI is not perfect in excluding biliary cancer, nor is SB, and their negative results should be interpreted with caution.

Abstract
BACKGROUND The diagnosis of cholangiocarcinoma (CCA) in patients with primary sclerosing cholangitis (PSC) is particularly difficult. The role of volatile organic compounds (VOCs) for diagnosis of CCA in patients with PSC is not known. OBJECTIVE Our aim was to identify potential VOCs in the headspaces (gas above the sample) in bile that may predict CCA in patients with PSC. DESIGN Prospective cross-sectional study. SETTING Referral center. PATIENTS A total of 32 patients undergoing ERCP for PSC and for CCA complicating PSC. INTERVENTIONS ERCP, bile aspiration. MAIN OUTCOME MEASUREMENTS Selected ion flow tube mass spectrometry was used to analyze the concentration of 22 prevalent VOCs in bile samples. Logistic regression analysis was performed to build a predictive model for diagnosis of CCA. RESULTS Levels of several compounds (ethanol, acrylonitrile, acetonitrile, acetaldehyde, benzene, carbon disulfide, dimethyl sulfide, 2-propranolol) were significantly different in patients with CCA complicating PSC compared with those having PSC (P < .05). By using receiver operating characteristic curve analysis, we developed a model for the diagnosis of CCA adjusted for age and sex based on VOC levels of acrylonitrile, 3-methyl hexane, and benzene. The model (2.3239*log [acrylonitrile] + 0.9871*log [3-methyl hexane] + 0.8448*log [benzene]) < -0.12 identified the patients with CCA (area under the curve [AUC] = 0.89), with 90.5% sensitivity and 72.7% specificity (P = .02). LIMITATIONS Sample size. CONCLUSION The measurement of VOCs in biliary fluid may be useful to diagnose CCA in patients with PSC. A larger study with a longitudinal study design is required to confirm our pilot observations to diagnose CCA early in patients with PSC. ( CLINICAL TRIAL REGISTRATION NUMBER NCT01565460.).

Abstract
BACKGROUND The role of M2-PK (pyruvate kinase) in bile has not been studied in comparison with brushings and carbohydrate antigen (CA) 19-9 in the diagnosis of malignant biliary strictures. AIM To compare the diagnostic accuracy of biliary M2-PK with cytology and serum CA 19-9 METHODS: In this prospective cross-sectional study, bile was aspirated in 74 patients (discovery and validation cohort) undergoing endoscopic retrograde cholangiopancreatography. Levels of M2-PK were measured in bile and compared to brushings for cytology and CA 19-9. RESULTS In the discovery cohort, the median bile M2-PK levels were significantly elevated in patients with malignant biliary strictures [187.9 U/l (interquartile range (IQR) 3.5, 3626.8)] compared to those with benign biliary conditions and primary sclerosing cholangitis [0 U/l (IQR 0, 15)] (P = 0.007). A M2-PK cutoff value of 109.1 U/l distinguished malignant from benign conditions with a sensitivity and specificity of 52.9 and 94.1 %, respectively, and area under curve (AUC) of 0.77. The sensitivity of CA 19-9 and brushings in diagnosing cancer was 52.9 % and 11.1 % and specificity 94.1 and 100 %, respectively. The presence of elevated M2-PK >109.1 U/l or CA 19-9 >33 U/ml or positive brushing was 88.2 % sensitive and 88.2 % specific, AUC of 0.89 in the diagnosis of malignancy. The diagnostic accuracy was confirmed in the validation cohort. CONCLUSIONS As a stand-alone factor, none of the markers were able to distinguish benign from malignant biliary strictures with a high sensitivity. However, a combination was highly sensitive in diagnosing malignant biliary strictures.

Abstract
BACKGROUND/AIMS Breast cancer is the most common tumor in women and the first cause of death for malignancy in the female population. Bile ducts are not among the common sites of metastasis from breast cancer; few cases of obstructive jaundice due to metastatic breast cancer have been described in the literature and they mostly resulted from widespread liver metastases that eventually involved the bile ducts. We report an exceptional case of metastatic infiltration of the extrahepatic bile ducts in absence of liver metastases. CASE PRESENTATION A 56-year-old woman who had undergone a right mastectomy 13 years earlier due to infiltrating ductal breast cancer and had remained tumor free, presented at a follow-up examination with obstructive jaundice.Imaging (computed tomography, magnetic resonance and endoscopic retrograde cholangiopancreatography) scans showed features that were suggestive of a primary tumor of the extrahepatic bile duct. At surgery, the intraoperative findings were also those of a tumor of the bile duct, however, an histological examination showed no evidence of malignancy in the mucosa, but did shown an infiltration of the external wall from adenocarcinoma. Immunohistochemistry analysis demonstrated that the tumor was metastatic breast cancer. CONCLUSIONS Indeterminate stenosis of the extrahepatic bile ducts should be examined with suspicion in women with a history of breast cancer, and bile duct metastases are to be considered among the possible diagnoses. A differential diagnosis from cholangiocarcinoma is of paramount importance and mainly relies on pathology.

Abstract
BACKGROUND Cholangiocarcinoma (CCA) is the most common hepatobiliary malignancy complicating primary sclerosing cholangitis (PSC). Unfortunately, timely diagnosis of CCA in PSC patients remains challenging. AIM To investigate the strategies among liver centers regarding pre-transplant screening for CCA in patients with PSC. METHODS An online survey was returned from 46 US transplant centers, inquiring on the frequency of screening, the use of specific tests, or tactical approaches to high-grade dysplasia (HGD) or CCA. RESULTS Most centers screen their PSC patients for CCA prior to orthotopic liver transplantation (OLT) (89%). Serum carbohydrate antigen 19-9 and magnetic resonance cholangiopancreatography are first-line screening tools (93 and 84% respectively). Endoscopic retrograde cholangiopancreatography with biliary brushings is routinely performed in only 30% of the centers. In the case of HGD, 61% would choose close monitoring. In the event of non-resectable CCA, 37% have an OLT protocol, 33% resort to palliative treatment and the remaining 30% make an outside referral. Finally, half the participating centers perform CCA surveillance among their listed PSC patients every 6 months. CONCLUSION Screening for CCA among PSC patients prior to OLT varies greatly among centers. Serum carbohydrate antigen 19-9 and magnetic resonance cholangiopancreatography are widely used. HGD warrants surveillance rather than intervention among most experts. Protocolized chemoradiation followed by OLT has yet to become a widely accepted approach. The very poor survival of PSC patients who develop CCA underlines the importance of an effective and universally accepted screening process that will aid in its earlier detection.

Abstract
AIM: To compare endoscopic retrograde cholangio-pancreatography (ERCP), intraductal ultrasound (IDUS), endosonography (EUS), endoscopic transpapillary forceps biopsies (ETP) and computed tomography (CT) with respect to diagnosing malignant bile duct strictures.
METHODS: A patient cohort with bile duct strictures of unknown etiology was examined by ERCP and IDUS, ETP, EUS, and CT. The sensitivity, specificity, and accuracy rates of the diagnostic procedures were calculated based on the definite diagnoses proved by histopathology or long-term follow-up in those patients who did not undergo surgery. For each of the diagnostic measures, the sensitivity, specificity, and accuracy rates were calculated. In all cases, the gold standard was the histopathologic staging of specimens or long-term follow-up of at least 12 mo. A comparison of the accuracy rates between the localization of strictures was performed by using the Mann-Whitney U-test and the χ2 test as appropriate. A comparison of the accuracy rates between the diagnostic procedures was performed by using the McNemar’s test. Differences were considered statistically significant if P < 0.05.
RESULTS: A total of 234 patients (127 males, 107 females, median age 64, range 20-90 years) with indeterminate bile duct strictures were included. A total of 161 patients underwent operative exploration; thus, a surgical histopathological correlation was available for those patients. A total of 113 patients had malignant disease proven by surgery; in 48 patients, benign disease was surgically found. In these patients, the decision for surgical exploration was made due to the suspicion of malignant disease in multimodal diagnostics (ERCP, CT, or EUS). Fifty patients had a benign diagnosis and were followed by a surveillance protocol with a follow-up of at least 12 mo; the median follow-up was 34 mo. Twenty-three patients had extended malignant disease, and thus were considered palliative. A comparison of the different diagnostic tools for detecting bile duct malignancy resulted in accuracy rates of 91% (ERCP/IDUS), 59% (ETP), 92% (IDUS + ETP), 74% (EUS), and 73% (CT), respectively. In the subgroup analysis, the accuracy rates (%, ERCP + IDUS/ETP/IDUS + ETP; EUS; CT) for each tumor entity were as follows: cholangiocellular carcinoma: 92%/74%/92%/70%/79%; pancreatic carcinoma: 90%/68%/90%/81%/76%; and ampullary carcinoma: 88%/90%/90%/76%/76%. The detection rate of malignancy by ERCP/IDUS was superior to ETP (91% vs 59%, P < 0.0001), EUS (91% vs 74%, P < 0.0001) and CT (91% vs 73%, P < 0.0001); EUS was comparable to CT (74% vs 73%, P = 0.649). When analyzing accuracy rates with regard to localization of the bile duct stenosis, the accuracy rate of EUS for proximal vs distal stenosis was significantly higher for distal stenosis (79% vs 57%, P < 0.0001).
CONCLUSION: ERCP/IDUS is superior to EUS and CT in providing accurate diagnoses of bile duct strictures of uncertain etiology. Multimodal diagnostics is recommended.

Abstract
Endoscopic ultrasound is one of those diagnostic methods in gastrointestinal endoscopy which has developed rapidly in the last decade and has became exceedingly available to visualize the walls of the internal organs in details corresponding to histological layers, or analyze the adjacent structures. Fine needles and other endoscopic accessories can be introduced into the neighbouring tissues under the guidance of endoscopic ultrasound, and diagnostic and minimally invasive therapeutic interventions can be performed. The endoscopic ultrasound became more widely available in Hungary in the recent years. This review focuses on the indications, benefits and complications of diagnostic and therapeutic endoscopic ultrasound. We dedicate this article for gastroenterologists, surgeons, internists, pulmonologists, specialists in oncology and radiology. This recommendation was based on the consensus of the Board members of the Endoscopic Ultrasound Section of the Hungarian Gastroenterological Society. Orv. Hetil., 2014, 155(14), 526–540.

Abstract
The majority of recent studies of benign biliary strictures (BBSs) have reported on treatment of stenotic injuries following cholecystectomy, orthotopic liver transplantation, living donor liver transplantation, chronic pancreatitis, and different inflammatory conditions such as common bile-duct-related strictures. Information about previous surgical procedures is very important for making a BBS diagnosis. Diagnostic tools for indeterminate strictures have increased to include (1) highly specialized cytological techniques such as fluorescence in situ hybridization, (2) cholangioscopy, and (3) endoscopic ultrasound with fine needle aspiration (FNA) and intraductal ultrasound. Magnetic resonance cholangiopancreatography before endoscopic retrograde cholangiopancreatography (ERCP) usually provides an adequate map to plan the endoscopic therapy. After traversing the stricture with a guidewire and, occasionally, performing balloon dilatation, plastic stents continue to be the basic endotherapy, trying to insert the maximum possible number, with an exchange every 3 months during a 12-month period. Progressive stenting requires a median number of five ERCPs; therefore, it is technically demanding and burdensome but has an average of 80% long-term durable stricture dilation. For not-hilar BBS, fully covered self-expanding metal stents (FCSEMSs) are emerging as a promising therapy needing fewer of the endoscopist's technical skills and reducing ERCP procedures and, probably, costs. To equal a 10-mm diameter provided by a single FCSEMS, about three plastic stents placed side-by-side are needed. Manufacturers are working to improve FCSEMS designs to reduce migration rate and to allow an easy extraction after several months in place. Many studies have tried to show reproducible protocols for the duration of FCSEMS therapy and the results in different types of BBSs.

Abstract
AIM: To assess the value of endoscopic ultrasonography in the auxiliary treatment of malignant obstructive jaundice.
METHODS: The clinical data for 105 patients with malignant obstructive jaundice who underwent endoscopic ultrasonography were retrospectively analyzed.
RESULTS: One hundred and five patients who were diagnosed with malignant obstructive jaundice by both endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasonography were included. Based on the clinical condition, endoscopic metal biliary endoprothesis was used in 61 patients, endoscopic retrograde biliary drainage in 39 patients, endoscopic nasobiliary drainage in 3 patients, and percutaneous transhepatic cholangial drainage in 2 patients. In the vast majority of patients, clinical symptoms were relieved and hepatic function was significantly recovered. The success rate of ERCP was 98.1%, and the rate of complications was 7.62%. Three patients had post-ERCP hyperamylasemia, 2 patients had mild cholangitis, and 3 patients had acute pancreatitis. During a follow-up period of 6.8 mo ± 5.3 mo (range, 1-18 mo), the half-year survival rate was 63.8% (67/105).
CONCLUSION: Endoscopic ultrasonography is a safe, effective and mildly invasive method for treating malignant obstructive jaundice.
