A 65-year-old man was scheduled for colonoscopy because fecal occult blood examination was positive.
When the colonoscope was inserted through the sigmoid colon, it suddenly became stuck and could not be inserted past this point.
A barium enema performed after colonoscopy showed that the sigmoid colon was involved in a left inguinal hernia. After the operation (tension-free hernioplasty), total colonoscopy was easily performed over a duration of about 5 minutes. Inguinal hernia frequently occurs in elderly people and is reported as a complication of colonoscopy. Before performing colonoscopy, it is important to perform a medical examination and interview the patient carefully about previous medical history.
