Sigmoid volvulus


Sigmoid volvulus is a cause of large bowel obstruction and occurs when the sigmoid colon twists on its mesentery. Symptoms are that of large bowel obstruction: constipation, abdominal bloating, nausea, and vomiting. Common causes are chronic constipation, laxative abuse, fiber-rich diet, and Chagas disease. In this case, the patient gave a history of chronic laxatives use.

Some surgeons consider that sigmoid volvulus is exclusively seen in the elderly, however, radiologists shouldn't do. Once imaging findings are straightforward for sigmoid volvulus, go on to your diagnosis regardless of the patient's age.
