Pancreas CancerOpen G tube to relieve nausea was posted 11/01/2005 09:21 pm by Susan in FMTX
The purpose of the G tube is to drain the green bile. It is surgically
implanted. If the stomach is unable to empty itself on it's own, then the G
tube, when open, allows the bile to drain. When the G tube is clamped and
the stomach is not working, the nausea becomes unbearable. The doctors want
the G tube to remain clamped as long as possible to try to coax the stomach
to contract and try to empty itself. My husband was supposed to start with
it clamped for 20 minutes and work up to 2 hours and then more. It was
impossible before the stomach paralysis ended.
The point is to get the stomach to start working. Do not introduce food by
mouth until she can keep the G tube clamped for hours. In the meanwhile,
like with my husband, the TPN can sustain.
The J tube goes directly into the jejunium (sp) and 'predigested' liquid food
is dripped into it. This feeding method is preferable to TPN if a J tube was
surgically implanted. However, if as in my husband's case, the J tube
migrates up into the (paralyzed) stomach, then tube feedings must be
discontinued because the stomach cannot empty itself.
