Duodenal ulcers, iatrogenic duodenal injuries, and blunt abdominal trauma are all possible causes of perforation of the extraperitoneal portion of the duodenum. A history of intermittent, crampy abdominal pain replaced by steady, unrelenting pain should suggest a closed loop obstruction with vascular compromise. A VA treatment record in February 28, 2008 indicated the Veteran had diarrhea four times the prior day with three normal stools.

Diffuse hepatic steatosis describes the pattern of fat dispersed throughout liver tissue. MeSH terms Diagnosis, Differential Flatulence / diagnostic imaging Gases* Humans In 1938, Weinstein described a condition known as cecal bascule, which involved folding of the right colon without twisting, so the cecum occupied a position in the midabdomen. A pseudo-Riglers sign may also result from Mach bands, a phenomenon in which there is the perception of a line at the interface between two areas of differing density (e.g., gas and soft tissue).

Gas X works wonders for me, but i, too, thought it was a bowel obstruction at first and was freaking out. In general, the transverse and ascending portions of the colon tend to become disproportionately dilated, but this is more a reflection of their anterior position within the abdomen or their underlying capacity to dilate than of a greater predisposition to disease. However, the amount of gaseous distention of these loops depends not only on the degree of obstruction, but also on the duration of obstruction, amount of air swallowing or emesis, and use of nasogastric suction for decompression. 12-11C ) or extrahepatic segment of the ligamentum teres in the right upper quadrant, the lateral umbilical ligaments (inverted V sign) in the lower abdomen, and the urachus. This type of scan is also sometimes called a KUB (kidney, ureter, and bladder study). Two separate air-fluid levels can sometimes be seen in the dilated transverse colon, a finding that helps differentiate volvulus of the transverse colon from cecal volvulus. Occasionally, however, gas may extend to the level of the sigmoid colon. 12-7 ), usually with the cecal apex in the left upper quadrant.

An adynamic ileus is typically manifested on abdominal radiographs by a dilated small bowel and colon, with multiple air-fluid levels on upright or horizontal beam decubitus views, so the presence of a dilated colon allows this condition to be differentiated from mechanical small bowel obstruction, in which only the small bowel is affected (see later, Small Bowel Obstruction ). Extraluminal air trapped between adjacent loops of bowel may also have a characteristic triangular appearance in patients with pneumoperitoneum ( Fig. Left psoas shadow -overlying bowel gas, fluid, inflammation .
