Gastroenterostomy as part of the palliation of unresectable cancer of the
head of the pancreas, in the absence of gastric outlet obstruction at the
time of surgery, has been both rejected, and, more recently, advocated for
all such patients. A study of 105 cases yielded four factors that
correlated with the subsequent occurrence of gastric outlet obstruction:
age, 60 years or younger; hemoglobin level, 11.5 g/dL or less; absence of
liver metastases; and survival, three months or longer. A fifth factor,
absence of clinical jaundice, may be an indicator of a poor prognosis with
a small risk of obstruction. By combining factors, we identified a group
with a risk of obstruction of at least 25% (those with two or more factors)
and one with negligible risk.
