[Chemical burns of the colon and rectum]

From the experimental data obtained in 104 animals and clinical observation of 270 cases of digestive tract chemical burns the authors have found that in response to the effect of a corrosion substance, got into the stomach, a complex of protective secretory motor reactions preventing in the most cases from the injury to the intestinal tract occur. In contaminations incompatible with life only, a superficial burn of the colon associated with injuries to the upper portions of gastrointestinal tract, does occur. This was found at the analysis of 62 postmortem protocols of the cases who died ater taking some chemical liquids.
