Splenic lymphoma with complex gastro-spleno-diaphragmatic fistula: 3D laparoscopic multivisceral resection. The first literature case report

Abstract

Introduction: Gastrosplenic fistula is a rare disease involving stomach and spleen that can lead to dangerous complications like massive gastrointestinal bleeding. Diffuse large B-cell lymphoma (DLBC) is the principal pathological cause of gastrosplenic fistula. Case report: We report a case of A 76-year-old caucasian woman came to the emergency room with fever for two week and gravative pain in left upper quadrant of the abdomen. CT scan of thorax and abdomen demonstrated an inhomogeneous hypodense large lymphomatous mass (10 × 6 cm) of upper pole of the spleen deformating medial profile and infiltrating gastric fundus and left diaphragm. with the diagnosis of complex gastro-splenic-diaphragmatic fistula we performed an en-block resection using a 3D laparoscopic vision system. Discussion: Gastrosplenic fistula is a rare complication of several clinical conditions. Among the different causes diffuse large B-cell lymphoma is the most frequent although diffuse histiocytic lymphoma, Hodgkin's lymphoma and extranodal NK/T-cell lymphoma are also described. After a literature review we found less then 30 cases of gastrosplenic fistula secondary to lymphoma. In our case report we do the first description of three-organs fistula envolvement, stomach, spleen and diaphragmatic dome, managed with 3D laparoscopic approach. Conclusion: Gastrosplenic fistula can represent a fatal evolution of splenic or gastric lymphoma independently from chemotherapy treatment. The diagnosis of this condition is very difficult and related to its rarity. To our opinion, laparoscopy represents a valid and safe alternative to open surgery in management of these patients.
