Extensive gastric mural gas is demonstrated, with associated portal venous gas in the left lobe of the liver. There is no intraperitoneal free gas demonstrated. There is mural thickening of the gastric antrum, duodenum and proximal jejunum. Some of the mid to distal small bowel also shows mural thickening in the right iliac fossa, though less severe than the proximal changes. The small bowel is dilated, measuring up to 4 cm in diameter, however there is no transition point to indicate that this is a mechanical obstruction, and faecal matter are seen throughout the colon.
