Colonic baro trauma resulting from an increase in intra-luminal pressure and may lead to perforation. In most cases such an injury is iatrogenic following air insufflation during colonoscopy and rarely due to industrial accidents. Most reported cases and existing literature advocates early radio imaging to diagnosed barotrauma to colon. We present a case report of a 36 years old male worker of a biscuit factory presented in our emergency department following exposure to high pressure air. However, in our case the perforation presented lately and repeated radio-imaging was unable to detect any signs of an impending perforation.
