Successful Conservative Treatment of an Elderly Patient with Corrosive Proctocolitis

Corrosive proctocolitis has occurred after accidental contamination of endoscopes in most patients. But accidental administration of corrosive agents for bowel cleansing can occur. The agents implicated for chemical colitis is 15% hydrochloric acid and 2% ethoxylated alcohol. We present a case of corrosive proctocolitis, present with anal pain and bloody diarrhea. Endoscopy revealed edema, erythema, and friability of the colonic mucosa. An experience of successful nonoperative treatments has been demonstrated.

Chemical colitis caused by hydrogen peroxide vaginal douche: A case report

BACKGROUND

Hydrogen peroxide is one of the most common household disinfectants worldwide. Hydrogen peroxide has been documented as a rare cause of chemical colitis.

CASE SUMMARY

We present a case of 31 years old lady who presented to our hospital with rectal bleeding and abdominal pain after using hydrogen peroxide vaginal douche as an enema. She underwent colonoscopy which showed findings suggestive of chemical colitis and was managed conservatively. Hydrogen peroxide can induce chemical injury in the colon. Clinical presentation and endoscopic findings of chemical colitis are nonspecific. History taking is an important tool in identifying the underlying etiology. Review of literature showed few case reports, mostly were managed with oral antibiotics and conservative approach.

CONCLUSION

Chemical colitis is usually managed conservatively. Complications including perforation, stricture and peritonitis may happen and need aggressive treatment accordingly.
