Letter to the Editor RE: "Gangrenous transverse colon volvulus in a male patient who underwent Hartmann's procedure. A rare case report"

• Sigmoid volvulus is the most common type of colonic volvulus and early recognition and intervention is essential. • Endoscopic detorsion is the initial step once bowel ischemia and perforation are absent clinically or radiologically. • Sigmoid colectomy is definitive management to reduce recurrence. • Metachronous transverse colon volvulus is a rare occurrence that can follow surgical operations for sigmoid volvulus.
