Case Discussion

History of multiple antibiotic use makes it likely to be pseudomembranous colitis. Empirically treated with oral metronidazole on admission. Fecal study shows the presence of C. difficile toxin, thus confirming the diagnosis. He was slow to respond to treatment and was changed to oral vancomycin, and then he gradually improved.

It is important to observe for development of perforation or toxic megacolon, as this would necessitate operative management.
