Factors ifluencing gastric emptying in patients with carcinoma of the
pancreas are complex and varied. Symptoms of gastric stasis are common
in patients with advanced cancer without overt duodenal involvement.
Delayed gastric emptying has also been observed in one-quarter of pati
ents with advanced pancreatic cancer undergoing gastrojejunostomy(1) T
he aetiology of delayed gastric emptying remains obscure. The mechanis
ms postulated for tumour-associated gastroparesis include autovagotomy
secondary retroperitoneal nerve invasion tumour-related gastroparetic
factor. The primary objective of this study was to examine gastric em
ptying before operation in patients with carcinoma of the pancreas and
to observe the effects of gastrojejunostomy on gastric function.
