AbstractAbstract PDFPubReaderePub
Antithrombotic agents, including antiplatelet agents and anticoagulants, are widely used in Korea because of the increasing incidence of cardiocerebrovascular disease and the aging population. The management of patients using antithrombotic agents during endoscopic procedures is an important clinical challenge. The clinical practice guidelines for this issue, developed by the Korean Society of Gastrointestinal Endoscopy, were published in 2020. However, new evidence on the use of dual antiplatelet therapy and direct anticoagulant management has emerged, and revised guidelines have been issued in the United States and Europe. Accordingly, the previous guidelines were revised. Cardiologists were part of the group that developed the guideline, and the recommendations went through a consensus-reaching process among international experts. This guideline presents 14 recommendations made based on the Grading of Recommendations, Assessment, Development, and Evaluation methodology and was reviewed by multidisciplinary experts. These guidelines provide useful information that can assist endoscopists in the management of patients receiving antithrombotic agents who require diagnostic and elective therapeutic endoscopy. It will be revised as necessary to cover changes in technology, evidence, or other aspects of clinical practice.

Quality indicators of endoscopic ultrasound in the pancreatobiliary system: a brief review of current guidelines
Sung Yong Han, Hyung Ku Chon, Seong-Hun Kim, Sang Hyub Lee, The Research Group for Endoscopic Ultrasound in Korean Society of Gastrointestinal Endoscopy
Clin Endosc 2024;57(2):158-163.   Published online June 9, 2023
DOI: https://doi.org/10.5946/ce.2023.064
AbstractAbstract PDFPubReaderePub
Since its development, the use of endoscopic ultrasonography (EUS) in the pancreas and the biliary tract has become increasingly important. The accuracy of EUS varies depending on the experience of the endoscopist. Hence, quality control measures using appropriate indicators are required to reduce these variations. American Society for Gastrointestinal Endoscopy and European Society of Gastrointestinal Endoscopy have announced the EUS quality indicators. Here, we reviewed the quality indicators of the EUS procedure in the current published guidelines.

Role of contrast-enhanced harmonic endoscopic ultrasonography (EUS) and EUS elastography in pancreatic lesions
Yasunobu Yamashita, Masayuki Kitano
Clin Endosc 2024;57(2):164-174.   Published online January 17, 2024
DOI: https://doi.org/10.5946/ce.2023.074
AbstractAbstract PDFPubReaderePub
Pancreatic cancers have a poor prognosis, and their incident rates have risen. Endoscopic ultrasonography (EUS) is an efficient and reliable diagnostic modality for pancreatic lesions, providing high spatial resolution. However, while EUS helps to detect minor pancreatic lesions, nearly all solid pancreatic lesions are hypoechoic, which creates difficulty in making differential diagnoses of pancreatic lesions. When diagnosing pancreatic lesions, the performance of image-enhanced EUS techniques is essential, such as EUS elastography or contrast-enhanced harmonic EUS (CH-EUS). CH-EUS diagnosis is based on assessing the vascularity of lesions, whereas tissue elasticity is measured via EUS elastography. Elastography is either strain or shear-wave, depending on the different mechanical properties being evaluated. The usefulness of enhanced EUS techniques is demonstrated in this review for the differential diagnosis of pancreatic lesions, including solid and cystic lesions, and pancreatic cancer staging.

Forward viewing liner echoendoscopy for therapeutic interventions
Kazuo Hara, Nozomi Okuno, Shin Haba, Takamichi Kuwahara
Clin Endosc 2024;57(2):175-180.   Published online February 29, 2024
DOI: https://doi.org/10.5946/ce.2023.271
AbstractAbstract PDFPubReaderePub
Therapeutic endoscopic ultrasonography (EUS) procedures using the forward-viewing convex EUS (FV-EUS) have been reviewed based on the articles reported to date. The earliest reported procedure is the drainage of pancreatic pseudocysts using FV-EUS. However, the study on drainage of pancreatic pseudocysts focused on showing that drainage is possible with FV-EUS rather than leveraging its features. Subsequently, studies describing the characteristics of FV-EUS have been reported. By using FV-EUS in EUS-guided choledochoduodenostomy, double punctures in the gastrointestinal tract can be avoided. In postoperative modified anatomical cases, using the endoscopic function of FV-EUS, procedures such as bile duct drainage from anastomosis, pancreatic duct drainage from the afferent limb, and abscess drainage from the digestive tract have been reported. When a perpendicular puncture to the gastrointestinal tract is required or when there is a need to insert the endoscope deep into the gastrointestinal tract, FV-EUS is considered among the options.

Graphical AbstractGraphical Abstract AbstractAbstract PDFSupplementary MaterialPubReaderePub
Background
/Aims: Radiofrequency ablation (RFA) is the first-line therapy for dysplastic Barrett’s esophagus (BE). Therefore, cryotherapy has emerged as an alternative treatment option. This study aimed to compare the efficacies of these two techniques based on the rates of complete eradication of intestinal metaplasia (CE-IM) and dysplasia (CE-D). Adverse events and recurrence have also been reported.
Methods
An electronic search was conducted using the Medline (PubMed), Embase, LILACS, and Google Scholar databases until December 2022. Studies were included comparing cryotherapy and RFA for treating dysplastic BE with or without early esophageal neoplasia. This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
Results
Three retrospective cohort studies involving 627 patients were included. Of these, 399 patients underwent RFA, and 228 were treated with cryotherapy. There was no difference in CE-IM (risk difference [RD], –0.03; 95% confidence interval [CI], –0.25 to 0.19; p=0.78; I2=86%) as well as in CE-D (RD, –0.03; 95% CI, –0.15 to 0.09; p=0.64; I2=70%) between the groups. The absolute number of adverse events was low, and there was no difference in the recurrence rate.
Conclusions
Cryotherapy and RFA were equally effective in treating dysplastic BE, with or without early esophageal neoplasia.

Background
/Aims: Hypoxemia is a common side effect of propofol sedation during endoscopy. Applying mild positive airway pressure (PAP) using a nasal mask may offer a simple way to reduce such events and optimize the conditions for diagnostic and therapeutic upper gastrointestinal endoscopies.
Methods
We compared overweight patients (body mass index >25 kg/m2) with a nasal PAP mask or standard nasal cannula undergoing upper gastrointestinal endoscopies by non-anesthesiologists who provided propofol sedation. Outcome parameters included the frequency and severity of hypoxemic episodes.
Results
We analyzed 102 procedures in 51 patients with nasal PAP masks and 51 controls. Episodes of hypoxemia (oxygen saturation [SpO2] <90% at any time during sedation) occurred in 25 (49.0%) controls compared to 8 (15.7%) patients with nasal PAP masks (p<0.001). Severe hypoxemia (SpO2 <80%) occurred in three individuals (5.9%) in both groups. The mean delta between baseline SpO2 and the lowest SpO2 recorded was significantly decreased among patients with nasal PAP mask compared to controls (3.7 and 8.2 percentage points difference, respectively). There were significantly fewer airway interventions performed in the nasal PAP mask group (15.7% vs. 41.2%, p=0.008).
Conclusions
Using a nasal PAP mask may be a simple means of increasing patient safety and ease of examination.

Novel upper gastrointestinal bleeding sensor capsule: a first human feasibility and safety trial
Lukas Bajer, Marvin Ryou, Christopher C. Thompson, Pavel Drastich
Clin Endosc 2024;57(2):203-208.   Published online January 17, 2024
DOI: https://doi.org/10.5946/ce.2023.111
Graphical AbstractGraphical Abstract AbstractAbstract PDFPubReaderePub
Background
/Aims: Upper gastrointestinal bleeding (UGIB) is the most common GI condition requiring hospitalization, and can be diagnosed by direct visualization. The present study aimed to evaluate the safety and feasibility of using the PillSense system (EnteraSense Ltd.), a novel diagnostic tool designed for the rapid in vivo detection of UGIB, in human volunteers.
Methods
In the present study, 10 volunteers swallowed a PillSense capsule, followed by 2 servings of an autologous blood preparation. Participants were monitored for capsule passage, overall tolerability of the procedure, and adverse events.
Results
The procedure was completed per the protocol established in the present study in 9/10 cases. In 9 of the subjects, after capsule ingestion, the device indicated the absence of blood with sensor output values of 1. After the ingestion of the first blood mixture, the sensor outputs of all devices increased from 2.8 to 4, indicating that each camera detected blood. The sensor output remained within that range after the ingestion of the second mixture; however, in one case, the baseline capsule signal was positive, because of a preexisting condition. The passage of the capsule was verified in all patients, and no adverse events were reported.
Conclusions
The first trial of the PillSense system in human subjects demonstrated the feasibility, safety, and tolerability of utilizing this product as a novel, noninvasive, and easy-to-use triage tool for the diagnosis of patients suspected of having UGIB.

Background
/Aims: Endoscopic ultrasonography-guided gastrojejunostomy is a minimally invasive method for the management of gastric outlet obstruction. Conventionally, a lumen-apposing metal stent (LAMS) is used to create an anastomosis. However, LAMS is expensive and not widely available. In this report, we described a tubular fully covered self-expandable metallic stent (T-FCSEMS) for this purpose.
Methods
Twenty-one patients (15 men [71.4%]; median age, 66 years; range, 40–87 years) were included in this study. A total of 19 malignant (12 pancreatic, 6 gastric, and 1 metastatic rectal cancer) and 2 benign cases were observed. The proximal jejunum was punctured with a 19 G needle. The stomach and jejunum walls were dilated with a 6 F cystotome, and a 20×80 mm polytetrafluoroethylene T-FCSEMS (Hilzo) was deployed. Oral feeding was initiated after 12 to 18 hours and solid foods after 48 hours.
Results
The median procedure time was 33 minutes (range, 23–55 minutes). After two weeks, 19 patients tolerated oral feeding. In patients with malignancy, the median survival time was 118 days (range, 41–194 days). No serious complications or deaths occurred. All patients with malignancy tolerated oral food intake until they expired.
Conclusions
T-FCSEMS is safe and effective. This stent should be considered as an alternative to LAMS for gastric outlet obstruction.

Background
/Aims: This study aims to compare polyp detection performance of “Deep-GI,” a newly developed artificial intelligence (AI) model, to a previously validated AI model computer-aided polyp detection (CADe) using various false positive (FP) thresholds and determining the best threshold for each model.
Methods
Colonoscopy videos were collected prospectively and reviewed by three expert endoscopists (gold standard), trainees, CADe (CAD EYE; Fujifilm Corp.), and Deep-GI. Polyp detection sensitivity (PDS), polyp miss rates (PMR), and false-positive alarm rates (FPR) were compared among the three groups using different FP thresholds for the duration of bounding boxes appearing on the screen.
Results
In total, 170 colonoscopy videos were used in this study. Deep-GI showed the highest PDS (99.4% vs. 85.4% vs. 66.7%, p<0.01) and the lowest PMR (0.6% vs. 14.6% vs. 33.3%, p<0.01) when compared to CADe and trainees, respectively. Compared to CADe, Deep-GI demonstrated lower FPR at FP thresholds of ≥0.5 (12.1 vs. 22.4) and ≥1 second (4.4 vs. 6.8) (both p<0.05). However, when the threshold was raised to ≥1.5 seconds, the FPR became comparable (2 vs. 2.4, p=0.3), while the PMR increased from 2% to 10%.
Conclusions
Compared to CADe, Deep-GI demonstrated a higher PDS with significantly lower FPR at ≥0.5- and ≥1-second thresholds. At the ≥1.5-second threshold, both systems showed comparable FPR with increased PMR.

Double-guidewire technique for selective biliary cannulation does not increase the rate of post-endoscopic retrograde cholangiopancreatography pancreatitis in patients with naïve papilla
Han Taek Jeong, June Hwa Bae, Ho Gak Kim, Jimin Han
Clin Endosc 2024;57(2):226-236.   Published online January 26, 2024
DOI: https://doi.org/10.5946/ce.2023.128
Graphical AbstractGraphical Abstract AbstractAbstract PDFPubReaderePub
Background
/Aims: This study aimed to compare the safety of the double-guidewire technique (DGT) with that of the conventional single-guidewire technique (SGT) in real-world situations.
Methods
A total of 240 patients with naïve papilla who underwent endoscopic retrograde cholangiopancreatography (ERCP) at Daegu Catholic University Medical Center between January 2021 and December 2021 were included. The primary outcome was the rate of post-ERCP pancreatitis (PEP) in the SGT and DGT groups.
Results
A total of 163 patients (67.9%) belonged to the SGT group, and 77 (32.1%) belonged to the DGT group. The rates of successful biliary cannulation were 95.7% and 83.1% in the SGT and DGT groups, respectively (p=0.002). In the study group, PEP occurred in 14 patients (5.8%). The PEP rates were not significantly different between the SGT and DGT groups (4.3% vs. 9.1%, p=0.150). In the multivariate analysis, the age of <50 years (odds ratio [OR], 9.305; 95% confidence interval [CI], 1.367–63.358; p=0.023) and hyperlipidemia (OR, 7.384; 95% CI, 1.103–49.424; p=0.039) were significant risk factors for PEP in the DGT group.
Conclusions
DGT did not increase the PEP rate in patients with naïve papilla. In addition, the age of <50 years and hyperlipidemia were significant risk factors for PEP in the DGT group.

Background
/Aims: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) using Franseen needles is reportedly useful for its high diagnostic yield. This study compared the diagnostic yield and puncturing ability of EUS-TA using 22-gauge cobalt-chromium (CO-Cr) needles with those of stainless-steel Franseen needles in patients with solid pancreatic lesions.
Methods
Outcomes were compared between the 22-gauge Co-Cr Franseen needle (December 2019 to November 2020; group C) and stainless-steel needle (November 2020 to May 2022; group S).
Results
A total of 155 patients (group C, 75; group S, 80) were eligible. The diagnostic accuracy was 92.0% in group C and 96.3% in group S with no significant intergroup differences (p=0.32). The rate of change in the operator (from training fellows to experts) was 20.0% (15/75) in group C and 7.5% (6/80) in group S. Stainless-steel Franseen needles showed less inter-operator difference than Co-Cr needles (p=0.03).
Conclusions
Both Co-Cr and stainless-steel Franseen needles showed high diagnostic ability. Stainless-steel Franseen needles are soft and flexible; therefore, the range of puncture angles can be widely adjusted, making them suitable for training fellows to complete the procedure.

Graphical AbstractGraphical Abstract AbstractAbstract PDFSupplementary MaterialPubReaderePub
Background
/Aims: Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (EUS-HGS) is useful for patients with biliary cannulation failure or inaccessible papillae. However, it can lead to serious complications such as bile peritonitis in patients with ascites; therefore, development of a safe method to perform EUS-HGS is important. Herein, we evaluated the safety of EUS-HGS with continuous ascitic fluid drainage in patients with ascites.
Methods
Patients with moderate or severe ascites who underwent continuous ascites drainage, which was initiated before EUS-HGS and terminated after the procedure at our institution between April 2015 and December 2022, were included in the study. We evaluated the technical and clinical success rates, EUS-HGS-related complications, and feasibility of re-intervention.
Results
Ten patients underwent continuous ascites drainage, which was initiated before EUS-HGS and terminated after completion of the procedure. Median duration of ascites drainage before and after EUS-HGS was 2 and 4 days, respectively. Technical success with EUS-HGS was achieved in all 10 patients (100%). Clinical success with EUS-HGS was achieved in 9 of the 10 patients (90 %). No endoscopic complications such as bile peritonitis were observed.
Conclusions
In patients with ascites, continuous ascites drainage, which is initiated before EUS-HGS and terminated after completion of the procedure, may prevent complications and allow safe performance of EUS-HGS.

Background
/Aims: Hepaticojejunostomy anastomotic stricture (HJAS) is a feared adverse event associated with hepatopancreatobiliary surgery. Although balloon dilation for benign HJAS during endoscopic retrograde cholangiopancreatography with balloon-assisted enteroscopy has been reported to be useful, the treatment strategy remains controversial. Therefore, we evaluated the outcomes and risk factors of recurrent stenosis after balloon dilation alone for benign HJAS.
Methods
We retrospectively analyzed consecutive patients who underwent balloon-assisted enteroscopy–endoscopic retrograde cholangiopancreatography for benign HJAS at our institution between July 2014 and December 2020.
Results
Forty-six patients were included, 16 of whom had recurrent HJAS after balloon dilation. The patency rates at 1 and 2 years after balloon dilation were 76.8% and 64.2%, respectively. Presence of a residual balloon notch during balloon dilation was an independent predictor of recurrence (hazard ratio, 2.80; 95% confidence interval, 1.01–7.78; p=0.048), whereas HJAS within postoperative 1 year tended to be associated with recurrence (hazard ratio, 2.43; 95% confidence interval, 0.85–6.89; p=0.096). The patency rates in patients without a residual balloon notch were 82.1% and 73.1% after 1 and 2 years, respectively.
Conclusions
Balloon dilation alone may be a viable option for patients with benign HJAS without residual balloon notches on fluoroscopy.

Single-pigtail plastic stent made from endoscopic nasobiliary drainage tubes in endoscopic ultrasound-guided gallbladder drainage: a retrospective case series
Koichi Soga
Clin Endosc 2024;57(2):263-267.   Published online April 4, 2023
DOI: https://doi.org/10.5946/ce.2022.213
AbstractAbstract PDFSupplementary MaterialPubReaderePub
Technical failure of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is often attributed to device failure. To rectify this problem, we developed a single-pigtail plastic stent (SPPS) for EUS-GBD. We retrospectively reviewed the cases of four patients who underwent EUS-GBD for acute cholecystitis. To prepare the SPPS, a 7.5-Fr endoscopic nasobiliary drainage tube was cut to an appropriate length. The use of SPPS during EUS-GBD was successful from both technical and clinical standpoints. The SPPS spontaneously detached 57 days after the procedure in patient 4 and 412 days after the procedure in patient 1. Patient 1 developed cholecystitis after 426 days and was managed with antibiotics. The other three patients did not develop any complications after surgery. In conclusion, we designed a new SPPS dedicated to EUS-GBD and established its technical feasibility and clinical effectiveness.
