Foregut

Territory · Oesophagus → D2 papilla Epigastric pain

Embryological gut segment supplied by the coeliac trunk: abdominal oesophagus, stomach, first and second parts of the duodenum to the major papilla, liver, gallbladder, pancreas and spleen. Visceral pain from these organs travels with the greater splanchnic nerves to T5–T9 and is felt in the epigastrium.

Detail

Extent
Abdominal oesophagus to the major duodenal papilla, plus liver, biliary tree, pancreas and spleen
Arterial supply
Coeliac trunk (T12)
Referred pain
Epigastrium (T5–T9, greater splanchnic nerve)

When it goes wrong

Peptic ulcer, early cholecystitis, pancreatitis

Poorly localised epigastric visceral pain; the coeliac plexus is the target of a coeliac plexus block for unrelenting pancreatic pain
