Sigmoid volvulus: a rare but unique complication of enteric fever.

We present a case of sigmoid volvulus in a young male patient with culture-proven Salmonella Typhi in the blood which was sensitive to Meropenem and Azithromycin only, presented with fever, vomiting, loose stools, hematochezia, abdominal distention and tenderness with no signs of perforation on erect chest x-ray. Further, radiological imaging showed signs of sigmoid volvulus. An urgent colonic decompression with untwisting of the mesentery was performed. In our case, it can be said that sigmoid volvulus was developed as a complication of multiple drug-resistant strains of Salmonella Typhi. The resistance is acquired by alteration in the genome sequence. Currently, it is important to control such an unknown outbreak of multiple drug-resistant strains of Salmonella Typhi as it is a serious health care issue of disease control and prevention in Pakistan.
