Analysis of 100 consecutive patients with pyloric outlet obstruction
revealed that 37% of the obstructions were secondary to peptic ulcer
disease and 42% were caused by malignant neoplasm. Only a single patient
with primary hypertrophic pyloric stenosis was identified, and whether this
lesion is a cause or effect of peptic ulcer disease remains unclear.
Similarly, the association of this entity with congenital pyloric stenosis
is unknown.
