Background/Aims: In clinical practice, colonoscopy has been regarded as the gold standard for the evaluation of disease se verity as well as mucosal healing in ulcerative colitis (UC). Some activity indices incorporating patient symptoms as parameters have been shown to reflect the endoscopic activity of UC. The aim of this study was to examine whether self-reported symp toms with visual analog scales (VAS) can predict endoscopic activity. Methods: A cross-sectional study of 150 UC patients who underwent colonoscopy with submission of VAS scores of 4 symptoms: general condition, bloody stools, stool form, and abdominal pain (0: no symptoms, 10: the most severe symptoms). Each VAS score was compared with colonoscopic activity assessed with the Mayo endoscopic subscore (MES). Results: All VAS scores were significantly correlated with the endoscopic severity (Spearman correlation coefficients of general condition, bloody stools, stool form, and abdominal pain: 0.63, 0.64, 0.58, and 0.43, respectively). Mucosal healing defined as MES 0 alone was predicted by VAS score <1.5 on general condition or 0 on bloody stools with sensitivity of 0.84 and 0.76 and specificity of 0.66 and 0.76, respectively. Additionally, VAS score <2.5 on stool form predicted active lesions in distal colorectum alone with sensitivity of 0.67 and specificity of 0.66, suggesting that this item could predict the indication of topical therapy. Conclusions: Self-reported VAS scores on symptoms were correlated with endoscopic activity of UC. To clarify the relationship between VAS and mucosal healing, further validation studies are needed.

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 wiregrasping method, forceps in the duodenum grasps a guidewire 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.

Background/Aims: Rosemont classification (RC) with endoscopic ultrasonography (EUS) is important for diagnosing chronic pancreatitis (CP) but is based only on subjective judgement. EUS shear wave measurement (EUS-SWM) is a precise modality based on objective judgment, but its usefulness has not been extensively studied yet. This study evaluated the utility of EUS-SWM for diagnosing CP and estimating CP severity by determining the presence of endocrine dysfunction along with diabetes mellitus (DM). Methods: Between June 2018 and December 2018, 52 patients who underwent EUS and EUS-SWM were classified into two groups according to RC: non-CP (indeterminate CP and normal) and CP (consistent and suggestive of CP). The EUSSWM value by shear wave velocity was evaluated with a median value. The EUS-SWM value was compared with RC and the number of EUS features. The diagnostic accuracy and cutoff value of EUS-SWM for CP and DM and its sensitivity and specificity were calculated. Results: The EUS-SWM value significantly positively correlated with the RC and the number of EUS features. The EUS-SWM values that were consistent and suggestive of CP were significantly higher than that of normal. The area under the receiver operating characteristic (AUROC) curve for the diagnostic accuracy of EUS-SWM for CP was 0.97. The cutoff value of 2.19 had 100% sensitivity and 94% specificity. For endocrine dysfunction in CP, the AUROC was 0.75. The cutoff value of 2.78 had 70% sensitivity and 56% specificity. Conclusions: EUS-SWM provides an objective assessment and can be an alternative diagnostic tool for diagnosing CP. EUS-SWM may also be useful for predicting the presence of endocrine dysfunction.

Background/Aims: Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been used to diagnose gastrointestinal submucosal tumors (SMTs). Although rapid on-site evaluation (ROSE) has been reported to improve the diagnostic accuracy of EUS-FNA for pancreatic lesions, on-site cytopathologists are not routinely available. Given this background, the usefulness of ROSE by endosonographers themselves for pancreatic tumors has also been reported. However, ROSE by endosonographers for diagnosis of SMT has not been reported. The aim of this study was to evaluate the diagnostic accuracy of EUS-FNA with ROSE by endosonographers for SMT, focusing on diagnosis of gastrointestinal stromal tumor (GIST), compared with that of EUS-FNA alone. Methods: Twenty-two consecutive patients who underwent EUS-FNA with ROSE by endosonographers for SMT followed by surgical resection were identified. Ten historical control subjects who underwent EUS-FNA without ROSE were used for comparison. Results: The overall diagnostic accuracy for SMT was significantly higher in cases with than without ROSE (100% vs. 80%, p=0.03). The number of needle passes by FNA with ROSE by endosonographers tended to be fewer, although accuracy was increased (3.3±1.3 vs. 5.9±3.8, p=0.06). Conclusions: ROSE by endosonographers during EUS-FNA for SMT is useful for definitive diagnosis, particularly for GIST.
