          Abstract

          Gastrocolic fistula (GSF) is a rare entity that arises mainly from splenic or gastric lymphoma. Gastric and splenic lymphomas can also fistulate with other organs, including the pleura and the colon, but there has been no reported case to best of our knowledge of a fistula involving three different organs. We hereby present the case of a female patient with gastrosplenocolic fistula secondary to non-Hodgkin B-cell lymphoma. We performed an en bloc partial gastrectomy with splenectomy and partial left colon resection with colostomy. GSF can be treated with chemotherapy. However, when the definite diagnosis is unclear or GSF is causing serious complications such as bleeding or active infection, we believe surgical excision is the treatment of choice.

          Gastrosplenic fistula occurring in lymphoma patients: Systematic review with a new case of extranodal NK/T-cell lymphoma

          AIM To provide the overall spectrum of gastrosplenic fistula (GSF) occurring in lymphomas through a systematic review including a patient at our hospital. METHODS A comprehensive literature search was performed in the MEDLINE database to identify studies of GSF occurring in lymphomas. A computerized search of our institutional database was also performed. In all cases, we analyzed the clinicopathologic/radiologic features, treatment and outcome of GSF occurring in lymphomas. RESULTS A literature search identified 25 relevant studies with 26 patients. Our institutional data search added 1 patient. Systematic review of the total 27 cases revealed that GSF occurred mainly in diffuse, large B-cell lymphoma (n = 23), but also in diffuse, histiocytic lymphoma (n = 1), Hodgkin’s lymphoma (n = 2), and NK/T-cell lymphoma (n = 1, our patient). The common clinical presentations are constitutional symptoms (n = 20) and abdominal pain (n = 17), although acute gastrointestinal bleeding (n = 6) and infection symptoms due to splenic abscess (n = 3) are also noted. In all patients, computed tomography scanning was very helpful for diagnosing GSF and for evaluating the lymphoma extent. GSF could occur either post-chemotherapy (n = 10) or spontaneously (n = 17). Surgical resection has been the most common treatment. Once patients have recovered from the acute illness status after undergoing surgery, their long-term outcome has been favorable. CONCLUSION This systematic review provides an overview of GSF occurring in lymphomas, and will be helpful in making physicians aware of this rare disease entity.

            Management of gastrosplenic fistula in the emergency setting - A case report and review of the literature

            Introduction A gastrosplenic fistula (GSF) is a very rare complication that arises mainly from a splenic or gastric large cell lymphoma. The proximity of the gastric fundus to the enlarged fragile spleen may facilitate the fistulisation. This complication can lead to massive bleeding, which, though uncommon, may be lethal. We present a patient with massive upper gastrointestinal bleeding secondary to a GSF. Case presentation We present a 48-year-old man with a refractory diffuse large B-cell lymphoma who was admitted to our hospital due to hematemesis. On arrival, he was in hemorrhagic shock, and was taken directly to the intensive care unit. The source of bleeding could not be identified on gastroscopy, the patient remained hemodynamically unstable and a laparotomy was performed. A fistula between a branch of the splenic artery and the stomach was identified. The stomach appeared to be involved in the malignant process. After subtotal gastrectomy and splenectomy, the bleeding was controlled. After stabilization, the patient was admitted to the intensive care unit, and 24 hours later was discharged in stable condition. Discussion We describe a fistula between a branch of the splenic artery and the stomach, which was accompanied by massive bleeding. An emergency laparotomy saved the patient's life. Conclusion The purpose of this report is to alert physicians that surgical intervention can be lifesaving in this rare malignant condition. A literature review focusing on the presenting symptoms and the epidemiology of GSF is presented.

              Successful Treatment of Gastrosplenic Fistula Arising from Diffuse Large B-Cell Lymphoma with Chemotherapy: Two Case Reports

              Gastrosplenic fistula (GSF) is a rare condition arising from gastric or splenic lymphomas. Surgical resection is the most common treatment, as described in previous reports. We report two cases of GSF in diffuse large B-cell lymphoma (DLBCL) patients that were successfully treated with chemotherapy and irradiation without surgical resection. Case 1 was of a 63-year-old man who had primary gastric DLBCL with a large lesion outside the stomach wall, leading to a spontaneous fistula in the spleen. Case 2 was of a 59-year-old man who had primary splenic DLBCL, which proliferated and infiltrated directly into the stomach. In both cases, chemotherapy comprising rituximab + dose-adjusted EPOCH regimen (etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin) was administered. Case 1 had significant bleeding from the lesion of the stomach during the treatment cycle; however, endoscopic hemostasis was achieved. Case 2 developed a fistula between the stomach and the spleen following therapeutic chemotherapy; however, no complications related to the fistula were observed thereafter. In both cases, irradiation was administered, and complete remission was achieved.
