Abstract
Background and study aims Endoscopic transpapillary biliary forceps biopsy (TBFB) is a common method for obtaining specimens from biliary lesions. Its diagnostic yield is unsatisfactory; to overcome this disadvantage, a dedicated sheath has been developed. This study aimed to evaluate the outcomes of conventional TBFB and TBFB with a novel sheath device. Patients and methods Consecutive patients who underwent TBFB between January 2020 and December 2021 were retrospectively evaluated. The rate of obtaining adequate samples, failed attempts at forceps insertion into the bile duct, and sensitivity were compared between the two groups. Results Ninety-two patients who underwent 115 endoscopic retrograde cholangiopancreatographies (76 in the conventional group vs. 39 in the dedicated sheath group) were included. The rates of obtaining adequate samples, failed attempts of the forceps into the bile duct, and sensitivity were 72.4% vs. 89.7% ( P = 0.03), 28.3% vs. 0% ( P < 0.01), and 66.7% vs. 88.9% ( P = 0.02), respectively. Conclusions TBFB with the novel sheath device contributed to improved sensitivity for diagnosis of biliary stricture without insertion of forceps outside the bile duct.

Innovative method for the diagnosis of bile duct lesions using a novel tapered-tip sheath system to facilitate biliary biopsies. Gastrointest Endosc 2023; 98:43-50.e1. [PMID: 36775209 DOI: 10.1016/j.gie.2023.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 01/26/2023] [Accepted: 02/06/2023] [Indexed: 02/14/2023]
Abstract
BACKGROUND AND AIMS Pathologic evaluation of bile duct lesions is crucial for a definitive diagnosis and determination of an appropriate therapeutic strategy; however, current methods are limited by several challenges. This study evaluated the impact of a novel tapered-tip sheath system on biliary stricture diagnosis. METHODS This observational study evaluated 47 consecutive patients who underwent transpapillary biliary stricture biopsy using the novel tapered-tip sheath system from July 2020 to March 2022 compared with 51 historical control subjects undergoing conventional biopsies. Technical success rate, total biopsy time, number of biopsy specimens, adequate tissue sampling rate, adverse events, and diagnostic performance for biliary strictures were assessed. RESULTS The technical success rate was favorable in both groups, showing no significant difference (97.9% [46 of 47] vs 88.2% [45 of 51], P = .114). However, the total biopsy time was significantly shorter in the novel system group (3.7 vs 7.7 minutes, P < .001). The number of biopsy specimens did not differ between the groups; however, the novel system group had significantly more cases in which ≥3 tissue samples could be obtained (71.7% [33 of 46] vs 51.1% [23 of 45], P = .043), a higher adequate tissue sampling rate (88.2% vs 66.4%, P < .001), and fewer adverse events (6.4% vs 21.6%, P = .043). Although the diagnostic specificity of both groups was 100%, the novel system group had significantly higher diagnostic sensitivity and accuracy (82.1% vs 50% [P = .004] and 84.8% vs 55.5% [P = .005], respectively). CONCLUSIONS The novel tapered-tip sheath system is a promising tool for biliary stricture diagnosis.

Abstract
A biliary stricture is an abnormal narrowing in the ductal drainage system of the liver that can result in clinically and physiologically relevant obstruction to the flow of bile. The most common and ominous etiology is malignancy, underscoring the importance of a high index of suspicion in the evaluation of this condition. The goals of care in patients with a biliary stricture are confirming or excluding malignancy (diagnosis) and reestablishing flow of bile to the duodenum (drainage); the approach to diagnosis and drainage varies according to anatomic location (extrahepatic vs perihilar). For extrahepatic strictures, endoscopic ultrasound-guided tissue acquisition is highly accurate and has become the diagnostic mainstay. In contrast, the diagnosis of perihilar strictures remains a challenge. Similarly, the drainage of extrahepatic strictures tends to be more straightforward and safer and less controversial than that of perihilar strictures. Recent evidence has provided some clarity in multiple important areas pertaining to biliary strictures, whereas several remaining controversies require additional research. The goal of this guideline is to provide practicing clinicians with the most evidence-based guidance on the approach to patients with extrahepatic and perihilar strictures, focusing on diagnosis and drainage.

Peroral Cholangioscopy-Guided Targeted Biopsy versus Conventional Endoscopic Transpapillary Forceps Biopsy for Biliary Stricture with Suspected Bile Duct Cancer. J Clin Med 2022; 11:jcm11020289. [PMID: 35053987 PMCID: PMC8779099 DOI: 10.3390/jcm11020289] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 12/29/2021] [Accepted: 01/03/2022] [Indexed: 01/27/2023] Open
Abstract
Background: The recent improvement of peroral cholangioscopy (POCS) maneuverability has enabled the precise, targeted biopsy of bile duct lesions under direct cholangioscopic vision. However, as only small-cup biopsy forceps can pass through the scope channel, the resulting small sample size may limit the pathological diagnosis of biopsy specimens. This study compared the diagnostic abilities of POCS-guided biopsy and conventional fluoroscopy-guided biopsy for bile duct cancer. Method: This multicenter, retrospective cohort study included patients exhibiting bile duct stricture with suspected cholangiocarcinoma in whom POCS-guided and fluoroscopy-guided biopsies were performed in the same session. The primary endpoint was the diagnostic sensitivity for malignancy. The size and quality of the biopsy specimens were also compared. Result: A total of 59 patients were enrolled. The sensitivity of POCS-guided biopsy was similar to that of fluoroscopy-guided biopsy (54.0% and 64.0%, respectively). However, when the modalities were combined, the sensitivity increased to 80.0%. The mean specimen size from POCS-guided biopsy was significantly smaller than that from fluoroscopy-guided biopsy. The specimen quality using fluoroscopy-guided biopsy was also better than that using POCS-guided biopsy. Conclusions: The diagnostic sensitivity of POCS-guided biopsy is still insufficient, mainly because of the limited specimen quantity and quality. Therefore, conventional fluoroscopy-guided biopsy would be helpful to improve diagnostic sensitivity.

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 and study aims The sensitivity of using standard endobiliary forceps biopsy to diagnose neoplastic biliary lesions remains low. We have developed a unique biopsy approach, termed fluoroscopy-guided, shaped endobiliary biopsy (FSEB), in which the biopsy forceps are modified to improve diagnostic yield. In this study, we evaluate the diagnostic characteristics of FSEB for endobiliary lesions at endoscopic retrograde cholangiography (ERC). Patients and methods Consecutive patients undergoing FSEB between 1/2001 and 12/2014 were retrospectively enrolled. The identification of neoplastic lesions with FSEB, was the primary endpoint. The gold standard of neoplasia was histopathology, cytology or surgical histopathology. The benign cases were followed up for one year. Results A total of 204 patients undergoing 250 biopsy sessions by FSEB were analyzed. Per-patient analysis was performed and FSEB showed 81.1 % sensitivity and 88.2 % accuracy. FSEB detection of proximal biliary lesions was more sensitive (91.1 % vs 73.2 %, P < 0.01) and accurate (94.9 % vs 82.2 %, P < 0.01) compared to distal lesions. No complications from FSEB were reported. Conclusions FSEB shows high accuracy for diagnosis of neoplasia in biliary strictures, especially for proximal lesions. Future prospective randomized controlled studies are merited to further validate the role of FSEB as the first-line sampling tool for evaluation of biliary neoplasm.

Abstract
BACKGROUND : Accurate preoperative assessment of the longitudinal extension of perihilar cholangiocarcinoma (PHCC) is essential for treatment planning. Mapping biopsies for PHCC remain challenging owing to technical difficulties and insufficient sample amounts. The aim of this study was to investigate the usefulness of a novel technique for mapping biopsies of PHCC. METHODS : Our novel method focused on a biliary stent delivery system for mapping biopsies. Fifty patients with PHCC undergoing endoscopic transpapillary mapping biopsy using the novel method were reviewed from August 2015 to June 2019. RESULTS : The median number of biopsy samples was six (range 1 - 17), and the rate of adequate sampling was 91.4 % (266 /291). Biopsy from the intrahepatic bile duct was possible in 82.0 % of patients (41 /50), and negative margins were confirmed in the resected specimens from 34 /39 patients who underwent surgery (87.2 %). None of the patients had post-endoscopic retrograde cholangiopancreatography pancreatitis. CONCLUSIONS : With our novel method, accurate assessment of the longitudinal extension of PHCC might be expected with minimal trauma to the duodenal papilla.

Abstract
Background: Peroral cholangioscopy (POCS)-guided forceps mapping biopsy (FMB) is a method for the accurate preoperative identification of the extent of the disease of biliary tract cancer (BTC). However, the diagnostic value of POCS-FMB is still uncertain. Objectives: We evaluated the diagnostic utility of POCS-FMB for the identification of lateral extension—superficial intraductal spread longitudinally and continuously from the main lesion—of BTC. Methods: In the retrospective study, patients who received POCS-FMB and surgery for curative resection of BTC between September 2016 and August 2019 at our medical institution were enrolled. The diagnostic accuracy of POCS-FMB for the identification of lateral extension of BTC was evaluated. Furthermore, we also evaluated the factors affecting the diagnostic accuracy of POCS-FMB. Results: A total of 23 patients with BTC were enrolled, and 24 procedures of POCS-FMB from 96 sites of biliary tracts were performed. The sensitivity, specificity, and accuracy of POCS-FMB were 53.8%, 63.9%, and 63.1%, respectively. In the multivariate logistic regression analyses, the biopsy from the bifurcation of biliary tracts was a significant factor affecting the diagnostic accuracy of POCS-FMB (odds ratio 3.538, 95%; confidence interval 1.151–10.875, p = 0.027). Conclusions: The diagnostic accuracy of POCS-FMB for the identification of lateral extension of BTC was insufficient. The biopsy from the bifurcation of biliary tracts was a positive factor affecting the diagnostic accuracy of POCS-FMB.

Abstract
Background Peroral cholangioscopy (POCS)-guided forceps biopsy is a method for diagnosing indeterminate biliary strictures and for the preoperative identification of the exact perihilar and distal margins of biliary tract cancer (BTC). However, POCS-guided forceps biopsy may result in an insufficient amount of specimen at times. Therefore, we evaluated the adequate tissue acquisition rate and the factors affecting the adequate tissue acquisition of POCS-guided forceps biopsy for the biliary tract. Methods Patients who underwent POCS-guided forceps biopsy for biliary disease between September 2016 and October 2018 at our hospital were enrolled retrospectively. We evaluated the adequate tissue acquisition rate of POCS-guided forceps biopsy for the biliary lesion and that for non-stenotic bile duct. In addition, the factors affecting the adequate tissue acquisition rate of POCS-guided forceps biopsy were evaluated. Results We enrolled 47 patients with biliary disease and performed POCS-guided forceps biopsy for biliary lesion and POCS-guided forceps mapping biopsy for non-stenotic bile duct in 40 and 36 patients, respectively. The adequate tissue acquisition rates of POCS-guided forceps biopsy for biliary lesions and that for non-stenotic bile duct were 86.4%, and 68.9%, respectively. In the multivariate logistic regression analyses, age, and previous biliary stenting before POCS were factors affecting the adequate tissue acquisition rate of POCS-guided forceps biopsy for the biliary lesion. For non-stenotic bile duct, the location of the biliary lesion, endoscopic sphincterotomy (EST), and procedure time of POCS were factors affecting the adequate tissue acquisition rate of POCS-guided forceps mapping biopsy. Conclusions Previous biliary stenting was a factor affecting a low tissue acquisition rate of POCS-guided forceps biopsy for the biliary lesion. In the POCS-guided forceps mapping biopsy, the location of the biliary lesion, EST, and procedure time were factors affecting tissue acquisition rates.

Abstract
Background and Aim Endoscopic retrograde cholangiopancreatography (ERCP)‐related tissue acquisition, including fluoroscopy‐guided forceps biopsy (F‐FB), is a common technique in diagnosing indeterminate biliary lesions. Recently, peroral cholangioscopy (POCS) and POCS‐guided forceps biopsy (POCS‐FB) has also been used for the diagnosis of indeterminate biliary lesions. However, it is uncertain which of those techniques were superior for the diagnosis of extrahepatic cholangiocarcinoma (ECC). We aimed to evaluate the diagnostic yield and safety of F‐FB for indeterminate biliary lesions compared with POCS‐FB. Methods Patients who underwent F‐FB or POCS‐FB to evaluate indeterminate biliary lesions between October 2011 and August 2019 were enrolled retrospectively. We carried out propensity score matching to balance these clinical differences between the F‐FB group and POCS‐FB group. In the propensity score‐matched cohort, we compared the diagnostic performance of F‐FB with that of POCS‐FB based on the pathological evaluation. We also evaluate adverse events associated with F‐FB and POCS‐FB. Results We enrolled 113 patients with biliary diseases, and 62 patients were analyzed in the propensity score‐matched cohort. Sensitivity, specificity, and accuracy of F‐FB were 82.4, 100, and 90.3%, and for POCS‐FB, those values were 83.3, 100, and 90.3%, respectively. There were no significant differences in the diagnostic performance between F‐FB and POCS‐FB. There were also no significant differences in the occurrence of adverse events between F‐FB and POCS‐FB (41.9 vs 29.0%, P = 0.289). Conclusions The diagnostic yield of F‐FB for ECC is similar to that of POCS‐FB. POCS‐FB is not necessary for the initial pathological diagnosis of indeterminate biliary lesions.

Abstract
These guidelines on the management of primary sclerosing cholangitis (PSC) were commissioned by the British Society of Gastroenterology liver section. The guideline writing committee included medical representatives from hepatology and gastroenterology groups as well as patient representatives from PSC Support. The guidelines aim to support general physicians, gastroenterologists and surgeons in managing adults with PSC or those presenting with similar cholangiopathies which may mimic PSC, such as IgG4 sclerosing cholangitis. It also acts as a reference for patients with PSC to help them understand their own management. Quality of evidence is presented using the AGREE II format. Guidance is meant to be used as a reference rather than for rigid protocol-based care as we understand that management of patients often requires individual patient-centred considerations.

Peroral Cholangioscopy-Guided Forceps Biopsy and Endoscopic Scraper for the Diagnosis of Indeterminate Extrahepatic Biliary Stricture. J Clin Med 2019; 8:jcm8060873. [PMID: 31248095 PMCID: PMC6616582 DOI: 10.3390/jcm8060873] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2019] [Revised: 06/12/2019] [Accepted: 06/18/2019] [Indexed: 12/15/2022] Open
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
BACKGROUNDS We aimed to investigate the diagnostic accuracy of multidetector-row computed tomography (MDCT), mapping biopsy, and other imaging modalities to predict the longitudinal extension and depth of invasion of extrahepatic cholangiocarcinoma at possible surgical ductal margins. METHODS Of 102 patients with surgical resection of extrahepatic cholangiocarcinoma between January 2010 and October 2015, 32 evaluated by multidetector-row computed tomography (MDCT) performed before biliary drainage and mapping biopsy were enrolled. Mapping biopsies were performed at 74 sites to determine the resection point of the bile duct (at 74 possible surgical ductal margins). Diagnostic accuracy was evaluated by histopathology. RESULTS The diagnostic accuracy of MDCT for longitudinal cancer spread was 79.7%, that of biopsy was 73.0%, and combining the two modalities showed highest accuracy (83.8%). The depth of tumor invasion could be predicted by combination of the ductal wall thickness and contrast enhancement on MDCT, that is, at 11 of 13 sites (84.6%) with submucosal invasion, ductal wall thickness was > 2.5 mm with high contrast enhancement. CONCLUSIONS MDCT demonstrated highest accuracy of diagnosing longitudinal extension at possible surgical ductal margins in patients with extrahepatic cholangiocarcinoma. The depth of tumor invasion could be predicted by ductal wall thickness and contrast enhancement of MDCT.

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
OBJECTIVE Biliary forceps biopsies are essential for differentially diagnosing biliary strictures and evaluating the preoperative superficial intraductal spread of bile duct cancers; however, these biopsies are technically demanding and time consuming. Using controllable biopsy-forceps (C-BF), which enable the tip's angle to be adjusted by up to 90°, may facilitate the procedure and improve the diagnostic yield for biliary biopsies. This study aimed to examine the efficacy of C-BF associated with the diagnosis of biliary strictures. MATERIALS AND METHOD Between 2009 and 2015, 110 patients with biliary strictures underwent biliary biopsies using C-BF. We retrospectively evaluated the diagnostic yield of C-BF for biliary strictures and determined the success rate associated with obtaining adequate samples during mapping biopsies to evaluate the superficial intraductal tumor spread. RESULTS The technical success rate for biliary biopsies using C-BF was 99% (109/110). The sensitivity, specificity and accuracy of the diagnoses of biliary strictures were 60% (46/77), 100% (33/33) and 72% (79/110), respectively. Regarding the mapping biopsy procedures, adequate samples were successfully obtained from 96% (22/23), 92% (11/12), 80% (12/15), 75% (9/12) and 31% (5/16) of the intrapancreatic common bile ducts, upper common bile ducts, confluences of the hepatic ducts, right intrahepatic bile ducts and left intrahepatic bile ducts, respectively. CONCLUSIONS C-BF may facilitate biliary cannulation and mapping biopsies of the common bile duct and the right intrahepatic bile duct. However, given that the diagnostic sensitivity was 60%, further modifications are expected and necessary to maximize the utility of the controllable mechanism.

Abstract
Background/Aims Transpapillary forceps biopsy is an effective diagnostic technique in patients with biliary stricture. This prospective study aimed to determine the usefulness of the wire-grasping method as a new technique for forceps biopsy. Methods Consecutive patients with biliary stricture or irregularities of the bile duct wall were randomly allocated to either the direct or wire-grasping method group. In the wire-grasping method, forceps in the duodenum grasps a guide-wire placed into the bile duct beforehand, and then, the forceps are pushed through the papilla without endoscopic sphincterotomy. In the direct method, forceps are directly pushed into the bile duct alongside a guide-wire. The primary endpoint was the success rate of obtaining specimens suitable for adequate pathological examination. Results In total, 32 patients were enrolled, and 28 (14 in each group) were eligible for analysis. The success rate was significantly higher using the wire-grasping method than the direct method (100% vs 50%, p=0.016). Sensitivity and accuracy for the diagnosis of cancer were comparable in patients with the successful procurement of biopsy specimens between the two methods (91% vs 83% and 93% vs 86%, respectively). Conclusions The wire-grasping method is useful for diagnosing patients with biliary stricture or irregularities of the bile duct wall.

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
A 78-year-old woman was referred to our hospital for the examination and treatment of jaundice. A transpapillary forceps biopsy for a long distal bile duct stricture was performed using endoscopic retrograde cholangiopancreatography. Immediately after the biopsy, massive bleeding was observed from the orifice of the papilla. Although hemobilia was pulsatile, an endoscopic biliary plastic stent placement was very effective in achieving hemostasis. However, a nasal biliary catheter was required because a blood clot clogged the stent on the following day. Although covered self-expandable metal stent (CSEMS) placement has been reported for achieving endoscopic hemostasis for bleeding, we chose to use a plastic stent to reduce the risk of post-procedure pancreatitis. The placement of both an endoscopic biliary plastic stent and a nasobiliary drainage catheter can be an alternative hemostatic tool to CSEMSs.

Abstract
BACKGROUND Cholangioscopy is used to diagnose and treat various biliary lesions. Balloon-assisted cholangioscopy (BAC) has mostly been reported in Asian patients with large bile ducts. OBJECTIVE To assess the feasibility and accuracy of performing BAC in complex biliary diseases in Australian patients. DESIGN Prospective observational study. SETTING A single Australian tertiary referral hospital. PATIENTS Fifty-nine consecutive patients (55 non-Asian ethnicity). INTERVENTIONS BAC using ultrathin endoscopes. MAIN OUTCOME MEASUREMENTS Procedural success rates, diagnostic accuracy, and adverse event rates. RESULTS Fifty-nine patients underwent 76 BAC procedures for indeterminate biliary lesions, ampullary adenomas, and difficult stone disease. The technical success rate was 93%. The median bile duct diameter was 7 mm (range, 2-20). Of 34 indeterminate biliary strictures, 22 appeared benign and 12 malignant on BAC appearance alone. All benign-appearing strictures were confirmed benign, whereas 9 of 12 malignant-appearing strictures were confirmed malignant by biopsy sampling or follow-up (sensitivity 100% [95% CI, 66%-100%], specificity 88% [95% CI, 69%-97%], positive predictive value 75% [95% CI, 42%-93%], negative predictive value 100% [95% CI, 82%-100%]). BAC appearance correctly diagnosed indeterminate masses as benign (4/4) or malignant (3/3). Eight patients were assessed for bile duct extension of ampullary adenomas and 5 of 6 had biliary stones cleared directly or with holmium laser lithotripsy. Adequate histopathologic specimens were obtained from 31 of 39 (79%) attempted biopsy specimens. The adverse event rate was 8%. LIMITATIONS A single-center, single endoscopist experience. CONCLUSIONS In a largely non-Asian cohort with smaller bile ducts, BAC can be performed with high success and acceptable adverse event rates. BAC is particularly useful in differentiating benign from malignant indeterminate biliary lesions.

INTERVENTION Each patient underwent peroral video-cholangioscopy with cholangioscopy-guided forceps biopsy. MAIN OUTCOME MEASUREMENTS The accuracy of diagnosis by the peroral video-cholangioscopic visual findings and cholangioscopy-guided forceps biopsy findings compared with that of the final diagnosis by other methods (malignant or benign). RESULTS Thirty-three patients were enrolled, and the final diagnoses revealed that the lesions were malignant in 21 patients. All procedures were technically successful, and fine views were obtained in all patients. Procedure-related complications occurred in 2 patients (6.1%), but these complications were mild. The sensitivity, specificity, and accuracy were 100%, 91.7%, and 97.0%, respectively, for the peroral video-cholangioscopic visual findings and 38.1%, 100%, and 60.6%, respectively, for the cholangioscopy-guided forceps biopsy findings, and a significant difference was observed in the accuracy (P = .0018). LIMITATIONS This was not a blinded study. No comparison was made with other diagnostic modalities involving tissue sampling. CONCLUSION The diagnostic accuracy of the peroral video-cholangioscopic visual findings for indeterminate biliary lesions was excellent and significantly higher than that of the cholangioscopy-guided forceps biopsy findings. The accuracy of the cholangioscopy-guided forceps biopsy was insufficient, but the technique had an excellent specificity.
