(B) A magnified view shows thickening of the small bowel folds (thin arrow).
Thinning of the bowel wall or "paper-thin wall" is caused by volume loss of tissue and vessels in the bowel wall and by the loss of intestinal muscular tone due to the lack of blood flow [ 32, 33].
A disadvantage of MRI relates to the absence of a universally acceptable bowel contrast agent, which in thin patients particularly can result in confusion between bowel and lymph node masses.
The bowel wall become thin, with a typical "paper thin" aspect [14, 21], the loops loose the tone, and now are only gas filled so spastic reflex ileus evolves into hypotonic ileus, peritoneal free fluid can be detected too [22].
For example, a thin patient's total small bowel volume is smaller than that of patients with normal body weight.
Diaphragm disease, characterized by thin septa that narrow the small-bowel lumen, is traditionally treated surgically by segmental resection.
The entity is relatively rare, but a significant cause of small bowel obstruction, especially in thin, elderly females [1 3].
Although bowel wall thickening is a common finding in cases of bowel ischaemia, the ischaemic bowel wall may also appear paper thin, particularly in cases of acute arterial occlusion [5].
In cases of acute arterio-occlusive transmural infarction, the bowel wall can become paper thin [10].
Following a midline incision, a small portion of the jejunum along with attached mesentery was carefully exteriorized, placed across a viewing cover glass, and superfused on a thin sheet of glass through which the bowel wall could be visualized.
The first and most plausible hypothesis suggests that an increase in the intraluminal pressure proximal to a stenosis causes a bowel distension to perforate the thin layer overlying a deep ulcer [ 8- 121 26, 26].
