What is a potential risk when using a rigid scope for esophagoscopy in Zenker's diverticulum?

• A. Infection
• B. Perforation
• C. Stenosis
• D. Bleeding

Answer: (B)

Using a rigid scope for esophagoscopy in Zenker's diverticulum presents a heightened risk of perforation. Zenker's diverticulum is an outpouching that occurs at the upper esophageal sphincter, typically due to muscular degeneration and increased pressure. The anatomy in this area can be altered and more fragile due to the presence of the diverticulum. When a rigid scope is employed, the lack of flexibility can lead to excessive force being applied against the wall of the esophagus or the diverticulum itself, increasing the risk of tearing the esophageal tissue. Furthermore, in cases where the diverticulum is large, navigating around it with a rigid instrument can further enhance the chances of causing a perforation. This risk underscores the importance of using appropriate techniques and tools tailored to the specific challenges posed by Zenker's diverticulum. While infection, stenosis, and bleeding can be potential concerns in any esophagoscopy procedure, the mechanical trauma from using a rigid scope specifically elevates the likelihood of perforation, making it a key risk factor to consider.
