Background: In cirrhotic patients with portal hyper-
tension prophylactic portasystemic shunts have been
found to be ineffective as deaths from post-shunt
liver failure exceed those from bleeding. However, in
patients with non-cirrhotic portal hypertension, va-
riceal bleeding rather than liver failure is the com-
mon cause of death. In developing countries short-
age of tertiary health-care facilities and blood banks
further increases mortality due to variceal bleed.
Aim: To study the results of prophylactic operations
to prevent variceal bleeding in patients with portal
hypertension due to non-cirrhotic portal fibrosis
(NCPF). Methods: Between 1976 and 2001, we per-
formed 45 prophylactic operations in patients with
NCPF, if the patients had high-risk esophagogastric
varices or symptomatic splenomegaly and hyper-
splenism. Proximal lienorenal shunt was done in 41
patients and the remaining underwent splenectomy
with (2 patients) or without (2 patients) devascular-
ization. Results: There was no operative mortality.
Thirty-eight patients were followed up for a mean 49
(range, 12-236) months. Three patients bled – one
was variceal and two due to duodenal ulcers; none
died of bleeding. There were 2 late deaths (6 weeks
and 10 years after surgery), one from an unknown
cause and one due to chronic renal failure. The
delayed morbidity was 47%. This included 7 patients
who developed portasystemic encephalopathy, 4 glom-
erulonephritis, 2 pulmonary arteriovenous fistulae
and 5 ascites requiring treatment with diuretics. Thus
only 20 (53%) patients were symptom-free on follow
up. Conclusions: Prophylactic surgery is safe and
effective in preventing variceal bleeding in NCPF but
at the cost of high delayed morbidity. [ Indian J

n cirrhotic patients the mortality rate from the
first episode of variceal bleeding has been reported
to range from 30% to 70%.

However, measures
to prevent the first bleed, such as endoscopic
sclerotherapy or portasystemic shunts, have not been
effective. In three of the four early trials
3-6
of
prophylactic portasystemic shunts, patients who
underwent operation did worse than those who did
not, with deaths from post-shunt liver failure
exceeding those from bleeding.
Non-cirrhotic portal hypertension is common in
India and the causes include extrahepatic portal venous
obstruction and non-cirrhotic portal fibrosis (NCPF).
This disease usually affects poor patients, who live
in rural areas far from medical centers and have
little or no access to facilities for blood transfusion.
In the West, patients with non-cirrhotic etiologies
have mortality ranging from 7% to 31% for a single
bleeding episode.

In a Japanese national survey
(1979-1988) of 671 cases of idiopathic portal hy-
pertension, 24 were managed conservatively. On
long-term follow up, the mortality was higher in the
non-operated group and the majority of deaths were
because of variceal hemorrhage.

Patients with NCPF generally have good liver
function and a lower incidence of post-shunt en-
cephalopathy.
9,10
For elective therapeutic splenorenal
shunt procedures (to forestall a second or subse-
quent bleed) the reported mortality rates are also
much lower than in cirrhotics.
11,12
We have per-
formed 285 elective proximal lienorenal shunt (PLRS)
operations in patients with NCPF with a low mor-
tality rate (0.8%), low variceal re-bleeding rate (8%)
and low post-shunt encephalopathy rate (13%).
12
We therefore reckoned, that in spite of their inef-
fectiveness in cirrhosis, it would be justifiable to
perform prophylactic operations on a selected group
of NCPF patients with high-risk varices and/or
hypersplenism who came from rural areas of the
country.
Methods
Between January 1976 and December 2001, 1180
patients with portal hypertension (extrahepatic portal
venous obstruction: 720, NCPF: 323, cirrhosis: 94,
hepatic venous outflow tract obstruction: 43) were
operated on at the Department of Gastrointestinal
Surgery, All India Institute of Medical Sciences. Of
these, 45 patients (age range 12-45 years, median 23;
