Endoscopic ultrasonography-guided biliary drainage: Who, when, which, and how?

open access: yesWorld Journal of Gastroenterology, 2016
Both endoscopic ultrasonography (EUS)-guided choledochoduodenostomy (EUS-CDS) and EUS-guided hepaticogastrostomy (EUS-HGS) are relatively well established as alternatives to percutaneous transhepatic biliary drainage (PTBD). Both EUS-CDS and EUS-HGS have

Esophageal Granular Cell Tumors Can Be Differentiated from Leiomyomas Using Endoscopic Ultrasonography

open access: yesInternal medicine, 2018
Objective Although esophageal granular cell tumors have been reported to present as hypoechoic tumors, we noticed that their echogenicity is similar to that of the submucosal layer.

Urinary stone disease: Great progress with promise for the future. [PDF]

open access: yes, 2012
Urinary calculus disease has been a scourge on mankind since ancient times. Research in the field has been hampered by lack of funds and the lack of cachet with the public such as seen with cancer or heart disease.

New endoscopic ultrasonography techniques for pancreaticobiliary diseases

open access: yesUltrasonography, 2016
Endoscopic ultrasonography (EUS) is widely used to evaluate pancreaticobiliary diseases, especially pancreatic masses. EUS has a good ability to detect pancreatic masses, but it is not sufficient for the differential diagnosis of various types of lesions.

Role of ultrasound in colorectal diseases [PDF]

open access: yes, 2009
Ultrasound is an undervalued non-invasive examination in the diagnosis of colonic diseases. It has been replaced by the considerably more expensive magnetic resonance imaging and computed tomography, despite the fact that, as first examination, it can ...

Human Endoscopic Ultrasonography

open access: yesGastroenterology, 1982
Conventional transcutaneous ultrasound examinations are often compromised by intervening pulmonary or bowel gas and have limited resolution. Ultrasonic probes of frequencies greater than 5 MHz, which enhance resolution, cannot be used successfully on the skin surface, because they do not penetrate deeply enough to view intraabdominal organs in most ...

NAT10 Increases Lysosomal Acidification to Promote Esophageal Cancer Metastasis via ac4C Acetylation of ATP6V0E1 mRNA

open access: yesAdvanced Science, EarlyView.
Zhan et al. demonstrate the vital role of NAT10‐catalyzed ac4C modification in regulating autophagy‐associated lysosomal acidification. They uncover the clinical and biological significance of ATP6V0E1, an important v‐ATPase assembly subunit, in tumor metastasis, particularly in the malignant progression of ESCC.
