title: [Neuroendocrine tumors of gastrointestinal tract in own material].
abstract: Neuroendocrine tumors are rare gastrointestinal tract disorders, in which diagnosis and treatment are often difficult. The aim of the paper is to present two cases of patients with neuroendocrine tumor of gastrointestinal tract, who underwent surgical procedure in II Department of General and Gastroenterological Surgery of Medical University of Białystok in 2005. A 63-year-old female patient with primary diagnosis of neuroendicrine tumor metastases in liver was not successfully investigated for primary tumor in the preoperative period. The laparotomy procedure indicated the malignant neuroendocrine tumor in the terminal ileum and metastases to the liver and to the greater omentum. The right hemicolectomy and liver metastatic segment VII and VIII resection were performed. The neurological disturbances of obscure origin were observed in the postoperative period and the patient suddenly died on the 15(th) day after surgery. A 57-years-old male patient was operated on for lymph node recurrence of gastric tumor. Pathologic examination of tissue sample revealed the diagnosis of carcinoid. The patient underwent subtotal gastric resection for a pyloric ulcer, diagnosed as Adenocarcinoma G2 pT2N0M0 6 years before. Liver and abdominal node metastases, confirmed by octreoscan, were observed after lymphadenectomy, The treatment of somatostatin analogues (LAR octreotide) was used. In spite of therapy the patient died. The authors present their own experiences and show the preoperative diagnostic difficulties in patients with neuroendocrine gastrointestinal tumors. Unexpected neurological complications in the treatment course were described.
