Procedure

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Biopsies are readily taken from the second part of the duodenum during upper gastrointestinal endoscopy. A Crosby-Watson capsule is swallowed and guided through the pylorus and duodenum with screening. When in position, a small sample of mucosa is obtained by suction, the capsule removed immediately and the sample placed in 10% formalin.

Complications:

sore throat - occasionally reported; transient
haemorrhage - rare, less than 0.1%.
perforation - extremely rare
retained capsule - extremely uncommon
