antrectomy

The operation usually performed is an antrectomy, the removal of the antral portion of the stomach.

Finally, the tumour was excised and antrectomy was performed to reduce the gastrin concentration.

The antrectomy (resection of the stomach antrum) is not part of the originally described procedure.

Surgery, consisting of excision of part of the lower stomach, also called antrectomy, is another option.

Antrectomy and reduction of gastrin levels had led to regression of gastric carcinoids.

The hypergastrinaemia and enterochromaffin like cell hyperplasia induced by these agents were abolished by antrectomy.

In one of our patients endoscopic removal of the carcinoid failed and local excision with accompanying antrectomy was performed.

After surgery involving the stomach and duodenum (most commonly with Billroth II antrectomy), a blind loop may be formed, leading to stasis of flow of intestinal contents.

The finding that the effect of omeprazole on the EC-like cells is prevented by antrectomy points to a crucial role for hypergastrinaemia in EC-like cell hyperplasia and carcinoid formation.

Although long term administration of pentagastrin can stimulate pancreatic growth and enterectomy causes hypergastrinaemia, elegant studies in rats with antrectomy or vagotomy have excluded its involvement in the response to PSBR.

The role of antrectomy in these apparently gastrin dependent tumours is still obscure, but there are reports of regression of fundic carcinoids after antrectomy and subsequent return to normal segum gastrin concentrations.
