Life-threating diarrhea and acute renal failure secondary to pancreatic VIPoma treated by surgery

Pancreatic neuroendocrine tumors represent less than 5% of all pancreatic tumors. They are a heterogeneous group of neoplasms with a diverse behavior and prognosis. Pancreatic vasoactive intestinal polypeptide tumor (VIPoma) is an exceptional tumor within this group due to its low incidence. The presence of pancreatic VIPoma should be clinically suspected in all patients with watery diarrhea, particularly when accompanied by a loss of potassium and bicarbonate and a pancreatic mass on imaging. There are other pathologies with similar symptoms; therefore, a correct differential diagnosis with an adequate treatment is essential for its management. We present the case of a 46-year-old patient who developed a prerenal kidney failure secondary to severe watery diarrhea after a diagnosis of pancreatic VIPoma. Thus, a resection was performed as the patient was rapidly deteriorating and required an intervention

Aplicación de sellantes de fibrina (Tissucol(R) frente a Tachosil(R)) para la prevención del seroma tras linfadenectomía axilar en cirugía del cáncer de mama. Estudio prospectivo y aleatorizado / Application of fibrin sealants (Tissucol(R) versus Tachosil(R)) for seroma prevention after axillary lymphadenectomy in breast cancer surgery. A prospective randomised study

Introducción: Los objetivos del estudio fueron valorar la utilidad de sellantes de fibrina para evitar seromas postoperatorios tras linfadenectomía axilar y comparar la incidencia de seroma axilar en 3 grupos de estudio (Tachosil(R), Tissucol(R) y control). Así mismo analizar posibles factores relacionados con la aparición del seroma. Métodos: Entre los años 2012 y 2015 se realizó un estudio prospectivo y aleatorizado en nuestro centro. Se incluyeron 110 pacientes consecutivas operadas de cáncer de mama que requirieron linfadenectomía axilar. Las pacientes fueron aleatorizadas en 3 grupos: Tachosil(R) (38 pacientes), Tissucol(R) (35) y control (37). Las variables estudio fueron: edad, peso, talla e índice de masa corporal, estadificación TNM del tumor, tipo histológico e inmunohistoquímico, número de ganglios extirpados, afectos, y uso de quimioterapia neoadyuvante. Las variables resultado fueron: débito obtenido por el drenaje desde el día 1 postoperatorio hasta la retirada del mismo, volumen total del drenaje axilar, aparición de seroma que precisara punción evacuación, volumen del seroma postoperatorio drenado y número de punciones evacuadoras hasta su resolución clínica. Resultados: No existieron diferencias significativas en el porcentaje de seromas, volumen y número de punciones evacuadoras necesarias para su resolución, ni tampoco respecto al débito a través del drenaje antes de su retirada entre los grupos de estudio. Los valores pronósticos para desarrollar seroma fueron: edad >56 años y débito al 6.° día posquirúrgico >70ml. Conclusiones: No se evidenciaron ventajas al aplicar sellantes de fibrina en relación con el volumen seroso drenado y con la formación de seroma axilar posquirúrgico

Introduction: The objectives of our study were to evaluate the usefulness of fibrin sealants in preventing the appearance of seromas after axillary lymphadenectomy and to compare the incidence of axillary seroma in three groups (Tachosil(R), Tissucol(R) and control). We also analysed the possible factors related to the development of seroma. Methods: Between 2012 and 2015, we carried out a prospective, randomised study at our centre including 110 consecutive patients undergoing breast cancer surgery who required axillary lymphadenectomy. Patients were randomised into 3 groups: Tachosil(R) (38 patients), Tissucol(R) (35) and control (37). Study variables consisted of age, weight, height and body mass index (BMI), tumour-node-metastases (TNM) stage, histological and immunohistochemical type, application of neoadjuvant chemotherapy, and the number of excised and metastasised lymph nodes. Outcome variables consisted of daily output from postoperative day 1 to the withdrawal of drainage, the total volume of axillary drainage, the appearance of postoperative seromas requiring puncture evacuation, the volume of the postoperative seroma drained and the number of seroma puncture evacuations required until clinical resolution. Results: There were no significant differences in the percentage of seromas, volume, number of puncture evacuations needed for resolution of the seroma or total flow through the drainage tubes prior to withdrawal in the 3 study groups. Prognostic values for the development of axillary seroma were age >56 years and a drained volume >70ml by the 6th postoperative day. Conclusions: We did not identify any advantages in applying fibrin sealants in relation to the serous volume drained or the incidence of postoperative axillary seroma

Hemoperitoneum secondary to perforated inflammatory myofibroblastic tumor: A case report of an unusual complication.

INTRODUCTION: Inflammatory myofibroblastic tumors (IMT) are rare neoplasms characterized by a proliferation of spindle-shaped cells with a stroma infiltrated by macrophages, lymphocytes and plasma cells. CASE REPORT: We report a case of 59 years old male who presented an acute abdomen due to a mass of the mesentery of the terminal ileum, which was perforated with active bleeding. Histopathology reported a low-grade TMI with clear margins. DISCUSSION: Inflammatory myofibroblastic tumors of the mesentery are rare entities whose etio-pathogenia remains unclear. It requires a histopathological diagnosis and inmunohistochemical evaluation and its treatment is based on complete resection of the tumor. These type of neoplasms require close monitoring due to local recurrence.
