Swirl Sign - Intestinal Volvulus after Roux-en-Y Gastric Bypass - Radiography (Panel A) and computed tomography (CT) (Panel B) showed dilated loops of small bowel distal to the jejunojejunostomy staple line with proximal decompression. Swirling of the bowel and mesenteric vessels was noted on CT as they herniated through the jejunojejunostomy mesenteric defect. #Clinical #Radiology #Surgery #KUB #CT #Swirl #Sign #SwirlSign #InternalHernia #Volvulus #IntestinalVolvulus #NEJM
