There is whirling of superior mesenteric vein around superior mesenteric artery in upper abdomen, from crainal to caudal aspect. There is associated whirling of small bowel loops; leading to complete small bowel obstruction. There are few fluid filled small bowel in upper abdomen with maximum diameter upto 24 mm. These dilated loops show mild hyperperistalsis. Small bowel loops distal to obstruction are collapsed.
Caecum is seen in right upper mid abdomen; lateral to inferior vena cava.
There is large encysted fluid with echoes anterior to small bowel, on both sides of abdomen. Whirling of small bowel causes anterior lobulation in this collection. Approximate size - 12 x 12 x 7 centimeter.
There is minimal anechoic fluid in pelvis.
