Small Bowel Obstruction These images were recorded from an elderly lady with abdominal pain and vomiting. Small bowel lumen is dilated more than 2.5cm and there is reduced peristalsis within the lumen - these sonographic signs are consistent with small bowel obstruction (SBO). Other signs of SBO include the presence of hyperechoic material moving back and forth within the bowel lumen and free fluid between the loops of bowel (Tanga sign).
