Abstract
We present a rare case of colon perforation caused by hydrostatic irrigation enema in a patient with chronic renal failure. A 76-year-old woman was admitted to our hospital because of an exacerbation of lumbar pain and increased difficulty in walking. She had a medical history of traumatic neck pain and chronic lower back pain, which had been treated with non-steroidal anti-inflammatory drugs (NSAIDs) for 8 years. On admission, the C-reactive protein level was 6.8 mg/dl, so we planned to do a colonoscopy to determine the cause of inflammation. The patient developed abdominal pain approximately 3.5 h after a pre-procedural enema was administered. An emergency operation was performed and a small perforation was found in the sigmoid colon. We conclude that the cause of the colon perforation was a combination of the use of a hydrostatic retrograde irrigation enema in a patient with chronic renal failure who had been treated with long-term NSAIDs.
