Rectal necrosis in the setting of critical illness and burn.

The rectum is an anatomically protected and well vascularized structure. Injury to the rectum is usually the result of penetrating perineal mechanisms or reported scalding enemas. Here, we report a case of isolated rectal necrosis following a 72 % total body surface area burn that resulted from a motor vehicle crash. The patient's rectal injury was managed with open resection, left in discontinuity and ultimately expired. In presenting this case, we hope to share an unusual development in a patient with critical illness and guide future care.
