Duodenal stenosis secondary to tuberculosis.

An 18-year-old man presented with complaints of epigastric pain, vomiting after meals, loss of appetite and weight, evening rise of temperature, and irregular bowel movements. Barium meal follow-through revealed a dilated stomach and first and second parts of the duodenum and stenotic lesion in the second part of the duodenum. Endoscopic biopsy of the stenotic lesion revealed acute on chronic nonspecific duodenitis with fibrosis. Isoperistaltic antecolic gastrojejunostomy was done to bypass the obstruction, and enlarged lymph nodes were biopsied. The biopsy of the enlarged lymph nodes revealed changes consistent with tuberculosis; therefore, the patient was started on antituberculous drugs in the postoperative period.
