Abstract
Gastrosplenic fistula is an unusual complication of benign as well as malignant gastric and splenic pathologies. This pathology acquires an important clinical significance due to its rare association with life-threatening upper gastrointestinal haemorrhage. The aim of this article is to review the English-language literature in order to gain a better understanding of etiological factors, diagnostic evaluation, and management of gastrosplenic fistula. The systematic search of the literature was performed on PubMed and MEDLINE from January 1950 to September 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. We retrieved 44 articles matching our selection criteria from the search. There were 3 case series, 37 case reports, and 4 review of the literature. In our appraisal of articles published in PUBMED, a total of 36 cases of malignant and 10 cases of benign gastrosplenic fistula could be identified. Gastrosplenic fistula is an exceptional complication of malignancies of the gastrointestinal tract. Lymphomas particularly arising from the spleen are the commonest cause. Gastric adenocarcinoma causing GSF is extremely rare. Most cases occur spontaneously, but at times, it can be secondary to tumour necrosis following chemotherapy.
