Useful Endoscopic Tricks for Stricture Management and Magnets

JL Yasuda et al. JPGN 2023; 76: 77-79. Measurement of Stricture Dimensions Using a Visual Comparative Estimation Method With Biopsy Forceps During Endoscopy

This quick study looked at using biopsy forceps in 191 endoscopies to estimate esophageal stricture narrowing. Key findings:

  • Lin’s concordance correlation coefficient was 0.92 (95% confidence interval: 0.89–0.94) between the visual diameter estimates and the fluoroscopic stricture measurements.
  • Correlation was strongest for smaller to mid-sized stricture diameters
  • Yellow biopsy forceps open wide to ~6 mm and standard orange biopsy forceps ~7 mm
  • Dimensions of the actual scope can be helpful in estimating a stricture. Some pediatric scope have 5-6 mm diameter and standard scopes ranging from 8.0-9.8 mm

My take: This study shows that commonly available endoscopic tools can be used to more accurately estimate stricture diameter.

Innovative Makeshift Technique for Removing Ingested Rare Earth Magnets “In this case, a makeshift technique of a prototype magnet in a net attracted the buried magnets within the food bolus and allowed successful retrieval of all intragastric magnets at once.” My take: This is a clever way to co-opt the enemy (the magnets). However, other useful approaches: 1. Many times an endoscopic forceps will attract the magnets 2. Using fluoroscopy, can be helpful in locating difficult to visualize objects
