Gastrosplenic fistula

Last revised by Yuranga Weerakkody on 9 May 2023

A gastrosplenic fistula is a very rare type of gut fistulation that can occur as a complication with either a gastric or splenic lesion.



Recognized causes include

Often requires extensive splenic necrosis and gastric wall infiltration (usually in the case of lymphoma) for gastrosplenic fistula formation. It may occur after chemotherapy as a result of rapid regression of tumor that has initially infiltrated the gastric mucosa.

Treatment and prognosis

Prognosis can be variable. Surgical resection is performed for many cases.
