Tuberculous disease of the duodenum, as an entity in itself and causing symptoms per se, is a very rare occurrence. The duodenum seems to be spared even when most of the remaining gastro-intestinal tract is involved. Perry and Shaw (1894), studying a series of 17,652 cases in which autopsy was done in Guy's Hospital in a period of sixty-six years, found only 11 cases of duodenal tuberculosis.

Schwatt and Steinbach (1923), in 199 cases of pulmonary and generalized intestinal tuberculosis found 3 in which the duodenum was involved. Gossmann (1913) performed autopsy in 2,360 cases of tuberculosis, only 5 of which showed duodenal
