early Bile Duct cancer detected by direct peroral cholangioscopy with narrow band imaging after Bile Duct Stone removal
Gut and Liver, 2011Co-Authors: Jong Ho Moon, Hyun Jong Choi, Jong Kyu Park, Sang Heum ParkAbstract:Cholangioscopy not only enables the direct visualization of the biliary tree, but also allows for forceps biopsy to diagnosis early cholangiocarcinoma. Recently, some reports have suggested the clinical usefulness of direct peroral cholangioscopy (POC) using an ultra-slim endoscope with a standard endoscopic unit by a single operator. Enhanced endoscopy, such as narrow band imaging (NBI), can be helpful for detecting early neoplasia in the gastrointestinal tract and is easily applicable during direct POC. A 63-year-old woman with acute cholangitis had persistent Bile Duct dilation on the left hepatic Duct after common Bile Duct Stone removal and clinical improvement. We performed direct POC with NBI using an ultra-slim upper endoscope to examine the strictured segment. NBI examination showed an irregular surface and polypoid structure with tumor vessels. Target biopsy under direct endoscopic visualization was performed, and adenocarcinoma was documented. The patient underwent an extended left hepatectomy, and the resected specimen showed early Bile Duct cancer confined to the Ductal mucosa. (Gut Liver 2011;5:377-379)

initial experience with a prototype peroral direct cholangioscope to perform intraDuctal lithotripsy with video
Gastrointestinal Endoscopy, 2011Co-Authors: Takao Itoi, Toshio Kurihara, Kentaro Ishii, Takayoshi Tsuchiya, Takuji Gotoda, Atsushi Sofuni, Shujiro Tsuji, Fumihide Itokawa, Jong Ho MoonAbstract:F s h Urakami et al1 first reported a peroral direct cholangiosopy (PDCS) procedure 3 decades ago. Recently, PDCS using ltraslim upper endoscopes has been described for diagnosic and therapeutic purposes.2-9 However, those endoscopes re not dedicated cholangioscopes. This is the first report of he use of a dedicated prototype peroral direct cholangiocope to fragment a difficult Bile Duct Stone.

endoscopic ultrasound guided antegrade treatment of Bile Duct Stone in patients with surgically altered anatomy a multicenter retrospective cohort study
Journal of Hepato-biliary-pancreatic Sciences, 2016Co-Authors: Takuji Iwashita, Takao Itoi, Hiroyuki Isayama, Yousuke Nakai, Kazuo Hara, Do Hyun ParkAbstract:Background Endoscopic retrograde cholangiopancreatography (ERCP) for management of Bile Duct Stone (BDS) in patients with surgically altered anatomy is challenging even when applying enteroscopy. Endoscopic ultrasound-guided antegrade treatments (EUS-AG) for BDS have been developed but have not been well studied yet. The aim of the present study was to evaluate the feasibility and safety of EUS-AG for BDS in patients with surgically altered anatomy as a multicenter retrospective cohort study. Methods A retrospective database analysis was performed to identify patients with surgically altered anatomy who underwent EUS-AG for the management of BDS at four academic care centers. Basic characteristics of the patients and details of the procedures were determined and the success rates and adverse event rates were evaluated. Results EUS-AG for BDS was attempted in 29 patients. Successful BDS removal was achieved in 72% (21/29) of patients. Reasons for failed EUS-AG were unsuccessful Bile Duct puncture in six, unsuccessful guidewire manipulation in one, and unsuccessful Stone removal using a retrieval balloon in one. Adverse events occurred in five (17%) but were successfully managed conservatively. Conclusion EUS-AG for BDS is a feasible and safe alternative in patients with surgically altered anatomy, although further evaluation and development of dedicated devices are needed.

short and long term outcomes of endoscopic papillary large balloon dilation with or without sphincterotomy for removal of large Bile Duct Stones
Scandinavian Journal of Gastroenterology, 2013Co-Authors: Hirofumi Kogure, Takeshi Tsujino, Hiroyuki Isayama, Naminatsu Takahara, Rie Uchino, Tsuyoshi Hamada, Koji Miyabayashi, Suguru Mizuno, Dai Mohri, Yoko YashimaAbstract:Abstract Objective. Removal of large Bile Duct Stones by endoscopic papillary large balloon dilation (EPLBD) with endoscopic sphincterotomy (EST) has been proven safe and effective. Little evidence supports the benefits of a preceding EST in reducing complications. Recent studies suggest that large Bile Duct Stone removal by EPLBD alone may be safe and effective. Material and methods. We removed large Bile Duct Stones by EPLBD with EST from March 2008 to February 2010 and without EST from March 2010 to October 2011. Efficacy and safety of EPLBD with or without EST and late biliary complication outcomes were assessed. Results. Forty-two patients (men/women, 27/15; mean age, 76 years) underwent EPLBD: 14 underwent EPLBD with EST and 28 underwent EPLBD without EST. The mean Stone size was 14 mm (9–30 mm). Overall complete Stone removal rate was 98%, with 83% achieved in 1 session. Complete Duct clearance by EPLBD alone was achieved in 79%. Mechanical lithotripsy was required in 4 (10%) patients.

endoscopic papillary balloon dilation for Bile Duct Stone immediate and long term outcomes in 1000 patients
Clinical Gastroenterology and Hepatology, 2007Co-Authors: Takeshi Tsujino, Haruhiko Yoshida, Hiroyuki Isayama, Hirofumi Kogure, Takashi Sasaki, Toshihiko Arizumi, Osamu Togawa, Takao Kawabe, Yutaka Komatsu, Saburo MatsubaraAbstract:Background & Aims: The long-term outcomes of endoscopic papillary balloon dilation (EPBD) for Bile Duct Stone removal are not well known. Methods: A total of 1000 patients with Bile Duct Stones were treated with EPBD. After assessing immediate outcomes, patients were followed up for late biliary complications. Results: Complete Bile Duct clearance was achieved with EPBD alone in 963 patients (96.3%) in a mean of 1.5 endoscopic sessions. Post-EPBD pancreatitis developed in 48 patients (4.8%), including 1 patient graded as severe. The long-term outcome was evaluated in 837 patients with a mean follow-up period of 4.4 years. Biliary complications were seen in 104 patients (12.4%), and they were less frequent in the cholecystectomy (CCx) after EPBD group than in the gallbladder (GB) left in situ with Stones, GB left in situ without Stones, and CCx before EPBD groups (2.8% vs 22.6%, 9.2%, and 13.5%, respectively). Stone recurrence was seen in 74 patients (8.8%)—2.4%, 15.6%, 5.9%, and 10.8% in the CCx after EPBD, GB left in situ with Stones, GB left in situ without Stones, and CCx before EPBD groups, respectively. Lithotripsy and gallbladder status were identified as risk factors for Stone recurrence. Cholecystitis occurred in 13 patients (4.5%) in the GB left in situ with Stones group. Conclusions: EPBD was effective in treating Bile Duct Stones that were not accompanied by an unacceptably high risk of pancreatitis. Patients with calculous gallbladder had the highest risk for late complications, and cholecystectomy is recommended after removal of their Bile Duct Stones.

endoscopic papillary large balloon dilation after endoscopic sphincterotomy for treatment of large common Bile Duct Stone
Digestive Endoscopy, 2007Co-Authors: Dong Ki Lee, Byungjun Lee, Sung Jun Hwhang, Yong Han Baik, Se Jun LeeAbstract:The extraction of large common Bile Duct (CBD) Stones after an endoscopic sphincterotomy is successful in most cases. However, the procedure often requires a prolonged time and repeated trials, therefore, subsequent occurrence of procedure-related complications are not uncommon. The purpose of the present paper was to investigate the utility of a combined endoscopic papillary large balloon dilation (EPLBD) preceded by a mid-incision endoscopic sphincterotomy for the removal of large CBD Stones. Stone removal was surprisingly effective with EPLBD in patients with large CBD Stones. Occurrence of major complication, such as pancreatitis, bleeding, and perforation, was not observed in any patients who were treated with EPLBD. EPLBD also can be safely carried out on patients with anatomic alteration, such as a periampullary diverticulum, and on patients who have undergone a Billroth II operation. EPLBD is a landmark method of removing a large CBD Stone, the impact of which is comparable to that of the introDuction of endoscopic mechanical lithotripsy. However, further investigation is required to address the applications and potential outcomes of this procedure. Also, procedure guidelines should be established to avoid major complications.
