It is associated with high morbidity and mortality, and surgical management is necessary for the majority of the cases. An accurate history and physical examination, plain radiographs of the abdomen, sigmoidoscopy, and, most important of all, awareness of the condition facilitate diagnosis in most cases. Operative intervention is warranted when massive hemorrhage, perforation, or peritonitis complicate the clinical scenario or medical therapy fails to control the disease. We sought to review the management challenges of TM and its possible management strategies in this article.Keywords: toxic megacolon, inflammatory bowel disease, management challenges and solutions for toxic megacolon, Clostridium difficile colitis, nitric oxide synthase
