Background
/Aims: Using an appropriate guidewire can increase the success rate of selective cannulation in endoscopic retrograde cholangiopancreatography. The purpose of this technical study was to investigate the characteristics of each guidewire type and to evaluate its efficiency and rapidity of insertion.
Methods
We conducted a three-point bending test using a universal testing machine to investigate the flexibility and bending features of each guidewire. 3D-printed silicone tubes with various types of stricture and a hand-made biliary tree silicone model with six-stranded intrahepatic ducts were used to evaluate the success rate and insertion time of each guidewire.
Results
In the three-point bending test, the characteristics of each guidewire were classified. We found that the bending strengths and times were independent of shaft thickness. Using two in vitro biliary duct models, we determined that the success rate and total insertion time were better for guidewires with a resilient shaft and angled tip than for other types of guidewires (p<0.001). Although thickness of the guidewire affected the success rate (p<0.05), it did not affect the total insertion time (p≥0.05).
Conclusions
Among several types of guidewire, some factors (resilient shaft, highly flexible, and angled tip) appeared to be associated with the efficiency and rapidity of the guidewire insertion.

Focused Review Series: Past, present and future of gastrointestinal stents
Basic Knowledge about Metal Stent Development
Seok Jeong
Clin Endosc 2016;49(2):108-112.   Published online March 22, 2016
DOI: https://doi.org/10.5946/ce.2016.029
AbstractAbstract PDFPubReaderePub
Biliary self-expandable metal stents (SEMS), a group of non-vascular stents, have been used in the palliative management of biliary obstruction around the world. However, there are still unmet needs in the clinical application of biliary SEMS. Comprehensive understanding of the SEMS is required to resolve the drawbacks and difficulties of metal stent development. The basic structure of SEMS, including the materials and knitting methods of metal wires, covering materials, and radiopaque markers, are discussed in this review. What we know about the physical and mechanical properties of the SEMS is very important. With an understanding of the basic knowledge of metal stents, hurdles such as stent occlusion, migration, and kinking can be overcome to develop more ideal SEMS.

AbstractAbstract PDFPubReaderePub

Endoscopic stenting is increasingly being used in the management of gastrointestinal luminal obstruction, and has become the current treatment of choice for the palliation of blockage caused by malignant or benign growths. A variety of stents have been developed to enhance the efficacy of the procedure, and improvements are ongoing. In this article, we review the history of, and recent advances in, gastrointestinal stenting. We describe the rationale behind the design as well as the resulting outcome for each stent type.

Twenty-Second versus Sixty-Second Dilation Duration in Endoscopic Papillary Balloon Dilation for the Treatment of Small Common Bile Duct Stones: A Prospective Randomized Controlled Multicenter Trial
Byoung Wook Bang, Tae Hoon Lee, Tae Jun Song, Joung-Ho Han, Hyun Jong Choi, Jong Ho Moon, Chang-Il Kwon, Seok Jeong
Clin Endosc 2015;48(1):59-65.   Published online January 31, 2015

AbstractAbstract PDFPubReaderePub
Background/Aims

Endoscopic papillary balloon dilation (EPBD) has been advocated as an alternative therapy to endoscopic sphincterotomy for the treatment of common bile duct (CBD) stones. However, there is no established consensus on the optimal balloon dilation duration (BDD). We prospectively evaluated the efficacy and post-endoscopic retrograde cholangiopancreatography (ERCP) complications between the 20- and 60-second EPBD groups.

Methods

A total of 228 patients with small CBD stones (≤12 mm) were randomly assigned to undergo EPBD with a 20- or 60-second duration at six institutions. We evaluated baseline patient characteristics, endoscopic data, clinical outcomes, and procedure-related complications. In addition, we analyzed risk factors for postprocedural pancreatitis.

Results

CBD stones were removed successfully in 107 of 109 patients (98.1%) in the 20-second group and in 112 of 119 patients (94.1%) in the 60-second group (p=0.146). Post-ERCP pancreatitis developed in seven patients (6.4%) in the 20-second group and nine patients (7.5%) in the 60-second group (p=0.408). In multivariate analysis, contrast dye injection into the pancreatic duct is a significant risk factor for post-EPBD pancreatitis.

Conclusions

Based on the data showing that there were no significant differences in safety and efficacy between the two BDD groups, 20 seconds of BDD may be adequate for treatment of small CBD stones with EPBD.

Endoscopic Submucosal Dissection Using a Novel Versatile Knife: An Animal Feasibility Study (with Video)
Chang-Il Kwon, Gwangil Kim, Il-Kwun Chung, Won Hee Kim, Kwang Hyun Ko, Sung Pyo Hong, Seok Jeong, Don Haeng Lee
Clin Endosc 2014;47(6):544-554.   Published online November 30, 2014
DOI: https://doi.org/10.5946/ce.2014.47.6.544
AbstractAbstract PDFSupplementary MaterialPubReaderePub
Background/Aims

In order to reduce the procedure time and the number of accessory changes during endoscopic submucosal dissection (ESD), we developed a novel versatile knife, which has the combined advantages of several conventional knives. The aim of this study was to compare the efficacy, safety, and histological quality of ESD performed using this novel versatile knife and a combination of several conventional knives.

Methods

This was an in vivo animal study comparing two different modalities of ESD in mini-pigs. Completion time of each resection was documented, and the resected specimens were retrieved and evaluated for completeness. To assess the quality control of the procedures and adverse events, detailed histopathological examinations were performed.

Results

A total of 18 specimens were dissected by ESD safely and easily (nine specimens using the new versatile knife; nine specimens by mixing conventional knives). All resections were completed as en bloc resections. There was no significant difference in procedure time between the 2 modalities (456 seconds vs. 355 seconds, p=0.258) and cutting speed (1.983 mm2/sec vs. 1.57 mm2/sec, p=1.000). The rate of adverse events and histological quality did not statistically differ between the modalities.

Conclusions

ESD with a versatile knife appeared to be an easy, safe, and technically efficient method.

Percutaneous Cholangioscopic Lithotripsy for Afferent Loop Syndrome Caused by Enterolith Development after Roux-en-Y Hepaticojejunostomy: A Case Report
Seong Hyun Kim, Seok Jeong, Don Haeng Lee, Sung Soo Yoo, Keon-Young Lee
Clin Endosc 2013;46(6):679-682.   Published online November 19, 2013
DOI: https://doi.org/10.5946/ce.2013.46.6.679
AbstractAbstract PDFPubReaderePub

Afferent loop obstruction caused by enterolith formation is rare and cannot be easily treated with endoscopy because of the difficulty associated with the nonsurgical removal of enteroliths. A 74-year-old woman was admitted with fever and acute abdominal pain. Clinical features and imaging studies suggested afferent loop obstruction caused by an enterolith after Roux-en-Y hepaticojejunostomy. Percutaneous transhepatic biliary drainage was initially performed because of severe cholangitis with septic shock. The enterolith was located in the jejunal limb adjacent to the hepaticojejunostomy site. Cholangioscopic lithotripsy was performed through the percutaneous transhepatic route to the enterolith, and the fragments were moved into the efferent loop using scope push and saline flush methods. Here, we describe a case of afferent loop syndrome caused by an enterolith that developed after Roux-en-Y hepaticojejunostomy and was treated with percutaneous transhepatic cholangio-enteroscopic lithotripsy.
