Article Synopsis
- Balloon-assisted enteroscopy (BAE) is an invasive procedure with risks like pain and perforation, but using lubricants can help reduce these risks.
- A study developed a model using human small intestines to measure dynamic friction coefficients (DFC) and find the ideal viscosities for low-friction lubricants.
- The results indicate that the viscosity of lubricants (0.20-0.32 Pa·s for overtube and 0.35-0.58 Pa·s for endoscopic shaft) significantly reduces DFC, suggesting that appropriate lubricants can make BAE less invasive.

Background: A novel rigidizing overtube (ROT) was developed to facilitate endoscopic removal of complex gastrointestinal polyps. We aimed to prospectively evaluate the efficacy and safety of the device in the management of large gastrointestinal polyps.
Methods: A prospective, single-center study, conducted between May 2021 and April 2023, enrolled patients undergoing endoscopic resection of colon/duodenal polyps ≥25 mm.
Efficacy of an assistive guide tube for improved endoscopic access to gastrointestinal lesions: an in vivo study in a porcine model.

Background/aims: Guide tube-assisted endoscopy for procedures that require repeated endoscopic access is safer and more effective than conventional endoscopy. However, its effectiveness has not been confirmed in animal studies. We assessed the usefulness of guide tube-assisted endoscopic procedures in an in vivo porcine model.

Introduction: Advanced endoscopic therapy techniques have been developed and have created alternative treatment options to surgical therapy for several gastrointestinal diseases. This work will focus on new endoscopic tools for special indications of advanced endoscopic resections (ER), especially endoscopic submucosal dissection (ESD), which were developed in our institution. This paper aims to analyze these specialized instruments and identify their status.
