Recent advancements in image-enhanced endoscopy in the pancreatobiliary field.

Image-enhanced endoscopy (IEE) has advanced gastrointestinal disease diagnosis and treatment. Traditional white-light imaging has limitations in detecting all gastrointestinal diseases, prompting the development of IEE. In this review, we explore the utility of IEE, including texture and color enhancement imaging and red dichromatic imaging, in pancreatobiliary (PB) diseases.

Noninvasive rapid urinary trypsinogen-2 dipstick test for early exclusion of post-endoscopic retrograde cholangiopancreatography pancreatitis within hours after endoscopic retrograde cholangiopancreatography: Clinical diagnosis and considerations.

Objective: Few reports have explored the application of urinary trypsinogen-2 measurement in the early diagnosis of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, and none have demonstrated the benefits of noninvasive testing. This study aimed to evaluate the clinical application of the rapid urinary trypsinogen-2 dipstick test (Nipro, Japan) compared with serum amylase and lipase levels for the early diagnosis of post-ERCP pancreatitis (PEP).

Methods: A total of 100 consecutive patients (54 men and 46 women) who were admitted and underwent ERCP at Tokyo Medical University Hospital from August 2021 to December 2021 were recruited.

Efficacy of gel immersion endoscopic ultrasonography for delineating the duodenal papilla and pancreatobiliary ducts: A retrospective study with video.

Objectives: Endoscopic ultrasonography is an important examination for periampullary diseases. The duodenum is filled with water to ensure a clear image and distend the duodenal wall without burying the papilla within duodenal folds; however, peristalsis frequently makes it difficult to maintain water within the duodenum. The gel immersion method (intestine is filled with viscosity gel) has recently been attracting attention.
