NCT ID: NCT05858827 Completed - Clinical trials for Artificial Intelligence

To Evaluate the Capability of an EUS Automatic Image Reporting System

Start date: May 10, 2023
Phase:
Study type: Observational

In this study, the EUS intelligent picture reporting system can automatically generate reports after reading videos of EUS examinations. This function can standardize the quality of endoscopic ultrasound image reporting and reduce the work burden of ultrasound endoscopists.

NCT ID: NCT05632900 Completed - Clinical trials for ENDOSCOPIC ULTRASONOGRAPHY

COMPARISON OF OUTCOMES OF BI-FLANGED METAL STENT ALONE VERSUS BI-FLANGED METAL STENT WITH CO-AXIAL PLASTIC STENT FOR DRAINAGE OF WALLED-OFF PANCREATIC NECROSIS - A PROSPECTIVE RANDOMISED CONTROLLED STUDY.

BFMSP
Start date: July 17, 2021
Phase: N/A
Study type: Interventional

Endoscopic ultrasound guided drainage of WON with metal stent is the mainstay of WON management. But there are few complications related to BFMS , like bleeding due to vessel erosion, stent clogging , stent migration . This study is to assess, whether placing an anchoring DPS through the BFMS will decrease adverse events or not. There are only 2 retrospective studies till date ,comparing LAMS with coaxial stent vs LAMS alone. one study showed no significant decrease in adverse events , one study showed decrease in adverse events when DPS with LAMS . But there has been no prospective RCT to assess the utility of DPS to date

NCT ID: NCT05457101 Recruiting - Clinical trials for Artificial Intelligence

Validation of an AI-based Biliopancreatic EUS Navigation System for Real-time Quality Improvement: A Prospective, Single-center, Randomized Controlled Trial

Start date: July 1, 2022
Phase: N/A
Study type: Interventional

Endoscopic ultrasonography (EUS) is a key procedure for diagnosing biliopancreatic diseases. However, the performance among EUS endoscopists varies greatly and leads to blind areas during operation, which impaired the health outcome of patients. We previously developed an artificial intelligence (AI) device that accurately identifies EUS standard stations and significantly reduces the difficulty of ultrasound image interpretation. In this study, we updated the device (named EUS-IREAD) and assessed its performance in improving the quality of EUS examination in a single-center randomized controlled trial.

NCT ID: NCT05448729 Not yet recruiting - Clinical trials for Endoscopic Ultrasonography

Shear Wave Elastography Versus Strain Elastography With Histogram Analysis in Solid Pancreatic Lesions

Start date: August 15, 2022
Phase: N/A
Study type: Interventional

to assess the diagnostic value of strain elastography EUS and shear wave EUS in solid pancreatic lesions

NCT ID: NCT04707560 Recruiting - Clinical trials for Pancreatic Neoplasms

Heparin-based Wet Suction Method in EUS Fine Needle Biopsy of Solid Pancreatic Mass

Start date: January 1, 2020
Phase: N/A
Study type: Interventional

The objective of this randomized cross-over trial is to evaluate whether Heparin based wet suction technique, compared with dry suction technique, shall present a higher quality tissue core by using quantitative macroscopic and microscopic scale.

NCT ID: NCT04549623 Recruiting - Sedation Clinical Trials

End-Tidal Carbon Dioxide Monitoring Device for Sedation During Endoscopic Ultrasonography

Start date: September 27, 2020
Phase: N/A
Study type: Interventional

To meet the needs of both operators and patients, moderate and deep sedation has been widely used in digestive endoscopy, which is invasive and painful. With its pleasant effects, sedation has complications nevertheless. And respiratory depression is the most common one, which makes respiratory monitoring significant. SpO2 and respiratory motion are regularly monitored without satisfying timeliness or sensitivity. Capnography with current device is only able to detect either oral or nasal breathing. The present study was designed to test the effect of the investigator's modified End-Tidal Carbon Dioxide (ETCO2) monitoring device for sedation during endoscopic ultrasonography-guided fine needle aspiration.

NCT ID: NCT03525847 Completed - Clinical trials for Endoscopic Ultrasonography

The Added Value of Contrast Enhancement for Guiding EUS-FNA in Solid Pancreatic Masses

Start date: January 1, 2017
Phase: N/A
Study type: Interventional

A prospective study designed to show the superiority of contrast guided echoendoscopy versus conventional echoendoscopy

NCT ID: NCT03292627 Completed - Clinical trials for Cholangiopancreatography, Endoscopic Retrograde

Non-invasive Monitor in Endoscopic Invasive Procedure

Start date: October 3, 2017
Phase:
Study type: Observational

Investigators include the patients who need painless invasive endoscopic procedure, investigators collect the demographic data and apply the non-invasive device ICON on participants during the who procedure.

NCT ID: NCT01479803 Completed - Pancreatic Tumor Clinical Trials

Comparison of Two Needles (ProCore vs EchoTip) for the Diagnosis of Pancreatic Solid Mass Under EUS

PICORE
Start date: October 2011
Phase: Phase 3
Study type: Interventional

The negative predictive value of fine needle aspiration under ultrasound endoscopy (EUS) for the diagnostic of solid pancreatic masses is 70% on average in the current literature with 22 gauge needles. There is a wide variability of this rate across studies (from 38 to 92%). In case of negativity of the biopsy, the risk of missing a pancreatic cancer whose prognosis is severe and extensive treatment, remains important. To improve the sensitivity of EUS echo endoscopy, several methods were used. A new needle (Echo Tip ® HD ProCore ™) has received CE Mark in the field of EUS. This instrument combines the comfortable and handy size of 22 Gauge and innovative design (window lateralized bevel) with in vitro studies obtaining core biopsy. In addition, a single pass through the tumor is achieved with this hand against several (2-3 minimum) with the current hardware. The theoretical goal is to have a tissue material more abundant during the sampling, without increasing morbidity and increase the diagnostic accuracy. A preliminary prospective study with this material has shown interesting results (increase the diagnostic accuracy of 15%). To determine the diagnostic gain with this new hand, it seemed essential to propose a prospective comparative study (22 gauge needle ProCore ™ versus the old EchoTip ® 22-Gauge) randomized (randomization of the order of the needles) in crossover (on the same lesion) in samples of pancreatic solid tumors. The caliber of 22 gauge is the gauge most often used for punctures under ultrasound endoscopy, resulting in less morbidity. Puncture by the 2 needles on the same injury can limit the effect of variability between patients and thereby have a better power for the investigators study without increasing the risk of complications (the needle ProCore ™ does not require that one pass through the tumor). The study of pancreatic solid tumors is one that poses the biggest diagnostic problem still present in the investigators daily practice. The aim of this study is to compare the diagnostic accuracy of the needle ProCore™ versus EchoTip® in etiological cyto histological diagnostic for pancreatic solid tumors under EUS.
