Novel slim biopsy forceps provide some technical advantages to facilitate a more accurate diagnosis, although we are not aware of any comparative studies. Therefore, we compared tissue acquisition and diagnostic accuracy between novel slim biopsy forceps and conventional biopsy forceps in cases with a biliary stricture. We reviewed 341 patients who underwent endoscopic retrograde cholangiopancreatography for the histological confirmation of biliary stricture at two tertiary hospitals between 2013 and 2020. The primary endpoint was the forceps’ diagnostic accuracies. We included 276 patients who underwent biopsy using the novel forceps (n = 130) or conventional forceps (n = 146). The novel forceps provided 81.7% sensitivity, 100.0% specificity, positive-predictive value (PPV) of 100.0%, and negative-predictive value (NPV) of 57.8%, with an accuracy of 85.4% when the diagnosis by endobiliary biopsy included suspected or positive malignancy. The conventional forceps provided 61.7% sensitivity, 100.0% specificity, PPV of 100.0%, and NPV of 36.1%, with an accuracy of 68.5%. Only novel forceps use was significantly associated with an accurate diagnosis (odds ratio: 2.70, 95% confidence interval: 1.52–5.00). There were no significant inter-group differences in the procedure-related rates of adverse events. Endobiliary biopsy using novel forceps offered better diagnostic performance and more acceptable procedure-related adverse events than conventional forceps.

Abstract Background Tissue sampling for biliary stricture is important for differential diagnosis and further treatment. The aim of this study was to assess a novel dilation catheter-guided mini-forceps biopsy (DCMB) method in the diagnosis of malignant biliary strictures. Methods 42 patients with malignant biliary stricture who underwent both brush cytology and DCMB during endoscopic retrograde cholangiopancreatography between October 2014 and November 2015 were retrospectively included. During DCMB, the mini biopsy forceps was introduced into the biliary stricture through the dilation catheter, and then the position and direction of the forceps were adjusted to obtain tissue samples. Results The positive rate of DCMB was significantly higher than that of brush cytology (81.0 % [34/42] vs. 38.1 % [16/42]; P < 0.001). No severe complications occurred; three patients (7.1 %) experienced mild procedure-related acute pancreatitis. Conclusions The novel DCMB technique was a practical, safe, efficient, and low-costing method for diagnosing malignant biliary stricture with a high accuracy rate.

Cannulation Success Rate

Background. Several previous studies assessed the competence in endoscopic retrograde cholangiopancreatography (ERCP) using the bile duct cannulation success rate. However, the cannulation time is also important, because a long cannulation time was reported to be a risk factor for post-ERCP pancreatitis. Aim. To determine the number of ERCP procedures required for short cannulation time of the bile duct. Methods. We retrospectively analyzed 605 ERCP procedures performed for bile duct cannulation in patients with native papilla at our institution between March 2012 and December 2015. The successful procedures were divided into 2 groups: group L and group S (cannulation time>15 minutes and ≤15 minutes, resp.). An analysis of the relationship among the biliary cannulation time, ERCP experience, and other factors was then conducted. Results. Multivariate analysis showed that the ERCP experience of ≤300 procedures (odds ratio, 2.080; 95% confidence interval, 1.337–3.142; P=0.001) and malignant biliary stricture due to pancreatic cancer (odds ratio, 1.912; 95% confidence interval, 1.072–3.412; P=0.028) were found to be significantly associated with a cannulation time of >15 minutes. Conclusions. Our findings suggested that an ERCP experience of ≤300 procedures and malignant biliary stricture due to pancreatic cancer were associated with prolonged biliary cannulation time.
