Gastro-caval fistula after distal esophageal resection: a case report and review of the literature.

Peptic ulceration with fistula formation into the inferior vena cava is rare, difficult to diagnose, and associated with high mortality. The nonspecific signs and symptoms make diagnosis challenging, delaying optimal treatment. Although there have been reports on duodeno-caval fistulas, gastric communication with the inferior vena cava is very rare. We report the second case of a fatal gastro-caval fistula and performed a review of the literature on entero-caval fistulas to emphasize the importance of early suspicion and to understand the most common presentation, as well as the best diagnostic and treatment modalities of this rare pathology.
