Recent reports describing bowel perforation during PCNL have emphasized the opportunity for non-operative management for the injury, with placement of the percutaneous nephrostomy tube into the bowel lumen
to act as a drain.
We placed magnetic toy beads within the bowel lumen
at intervals along its length.
The water content produces high signal within the bowel lumen
on T2W images against a normally low-signal bowel wall.
The sign has a tendency to disappear or become less apparent when the bowel lumen
is more distended.
The theory of "mucin lakes" formation is that the low-grade neoplasm produces mucin that distends the bowel lumen
8 L since it osmotically draws plasma water into the bowel lumen
But with negative contrast agents, the bowel lumen
appears dark and the wall appears white.
A follow-up CT scan of the abdomen demonstrated a 3-cm partially necrotic solid mass in the mesenteric border of the mid-portion of the small bowel, stretching and narrowing the bowel lumen
6) The tumor of patient 1 protruded in a cauliflower-like pattern into the bowel lumen
adjacent to the ileocecal valve.
LumenHance will cause the bowel lumen
to appear either dark or bright on MR images, depending on the imaging technique used.
In addition, surgical staples leave permanent foreign material within the bowel lumen
, and the bowel is often left with a reduced lumen size.
A tumour nodule within the jejunal mesentery had eroded into the bowel lumen
, and was associated with distal gastrointestinal hemorrhage (the cause of the melena).
