Refractory
ascites |
Is defined as ascites
unresponsive to 400 mg of
spironolactone
or
30 mg of amiloride plus up to 120 mg of
furosemide daily for two weeks.
Noncompliance with sodium restriction is a
major and often overlooked cause of
resistant ascites, and careful questioning
of the patient and the patient's relatives
is often required to confirm this.
Other
causes of resistant ascites include the
development of spontaneous bacterial
peritonitis, hepatocellular carcinoma and
intrinsic renal pathology.
Refractory
ascites without any underlying cause usually
indicates advanced cirrhosis associated with
a grave prognosis, with only a 50% survival
at two years.
Treatment:
1-Large-volume paracentesis is
now recognized as a safe and effective
therapy for the treatment of refractory
ascites. Removal of ascitic fluid volume of
up to 5 L without the simultaneous infusion
of plasma expanders such as concentrated
albumin is safe in non-edematous patients.
Larger volumes can be removed in edematous
patients. However, repeated paracenteses may
not be practical for all patients with
refractory ascites, and a peritoneovenous(
LeVeen Shunt
) should be considered in
selected patients with good liver reserve.
It may be dramatically effective in
resolving the ascites, but in patients with
decompensated liver disease it is followed
by higher morbidity and mortality. Previous
abdominal surgery, spontaneous bacterial
peritonitis and large varices are relative
contraindications to the procedure.
Early
complications: include pulmonary edema and
disseminated intravascular coagulopathy.
Late complications: include thrombosis of the
superior vena cava, infection and blockage
or dislodgement of the shunt, all of which
require its immediate removal.In suitable
patients, the LeVeen shunt, in addition to
improved management of ascites, can
significantly enhance well-being and
nutritional status. 2-Transjugular intrahepatic portal-systemic shunt (TIPS) has been shown to be an
effective means of managing refractory
ascites. This method involves creating a
communication between a branch of the
hepatic vein and a branch of the portal vein
held open by a metal stent.
3-Liver
transplantation should always be
considered as a treatment option. |
