Ulcerative colitis is a relapsing nontransmural inflammatory disease restricted to colon, which may be classified as proctitis, left-sided colitis, or pancolitis depending on the extent of involvement. Some patients also develop ileal inflammation (backwash ileitis), which occasionally complicates its differentiation from Crohn's ileocolitis. Crohn's disease is defined as a relapsing transmural inflammatory disease of gastrointestinal mucosa that may affect the entire gastrointestinal tract (GIT) from the mouth to the anus. There is discontinuous involvement of various portions of the GIT and may get complicated by formation of strictures, abscesses, or fistulas. It closely resembles intestinal tuberculosis both clinically and on investigations. GI tuberculosis is often suspected on the basis of its clinical, radiological, and endoscopic features, but histological or microbiologic proof of the disease is often difficult to achieve. Therefore, the majority of patients are treated with antitubercular drugs on presumptive diagnosis only. Similar clinical, endoscopic, radiological, and histological features of GI tuberculosis and Crohn's disease pose a serious challenge to the treating physician. The rate of misdiagnosis of these conditions using conventional diagnostic measures has been reported to be around 50-70%. Thus d
