Filter by: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.
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
A prospective study designed to show the superiority of contrast guided echoendoscopy versus conventional echoendoscopy
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.
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.
