Intestinal volvulus is defined as a twisting of the bowel on its mesentery. It itself is a rare occurrence, with documented incidence of 1% as the cause of all small bowel obstruction, with further 0.82% of them being associated with intestinal malrotation. The classical radiographic feature described in literatures is the whirlpool sign. We herein report a rare presentation of congenital malrotation causing a small bowel obstruction in a 43-year-old man. The patient presented with acute abdominal pain and underwent an emergency laparotomy and resection of small and large bowel (total of 3 m with primary anastomosis), with an estimated 2.6 m of viable small bowel left. The patient had a prolonged recovery complicated by another relook operation, superior mesenteric vein thrombus and a high-output stoma with subsequent electrolyte derangements and acute kidney injury. He was discharged on Day 26 and had been seen in the outpatient department with good functionality. [ABSTRACT FROM AUTHOR]
