INFO/WWW:
In
small bowel obstruction vomiting occurs earlier, distension is less and the
pain is higer in the abdomen. On AXR small bowel obstruction shows central
gas shadows (gas-fluid interfaces, horizontal fluid level) and there is no
gas in the large bowel. Small bowel is identified by valvulae conniventes
which completly cross the lumen - in contrast large bowel haustra do not cross
all the lumen`s width. Causes: Adhesions, Herniae, intususception, paralytic
ileus, tumour, gallstones In large bowel obstuction pain is more constant.
On AXR gas is ususally proximal to the blockage located.
D:
Paralytic
ileus caused by acute pancreatitis
