Abstract

Gastrosplenic fistula is a rare and potentially fatal clinical entity unknown to most healthcare providers. Its diagnosis and management are challenging; and addressing it too late can have devastating consequences for patients. To increase awareness about this pathology, we hereby present a case of asymptomatic gastrosplenic fistula arising from a diffuse large B cell lymphoma in a 60-year-old Caucasian man with no significant medical history. The patient was successfully treated with open en-bloc splenectomy and partial gastrectomy. The patient was discharged from the hospital 3 days after the surgery. At 1-month postoperatively, the patient was asymptomatic and presented no complication of the surgery. He went on to finish six cycles of chemotherapy (R-EPOCH, rituximab, etoposide phosphate, prednisone, vincristine sulfate, cyclophosphamide, doxorubicin hydrochloride) and achieved complete metabolic response. At 2 years after the surgery, the patient remains asymptomatic and presents no sign of disease recurrence.
