Description
A contingency table relating surgical operation, centre and severity of
gastric dumping, a syndrome associated with gastric surgery.
Usage
data(dumping)
Format
A 3x4x4 table of counts cross-classified by Symptom
(none/slight/moderate), Operation (Vd/Va/Vh/Gr) and Centre (1:4).
Details
Gastric dumping syndrome is a condition where ingested foods bypass the
stomach too rapidly and enter the small intestine largely undigested. It is
an undesirable side-effect of gastric surgery. The table summarizes the
results of a study comparing four different surgical operations on patients
with duodenal ulcer, carried out in four centres, as described in Grizzle et
al (1969). The four operations were: vagotomy and drainage, vagotomy and
antrectomy (removal of 25\
