ABSTRACT

Background: Short bowel tumors correspond to 2 percent of gastrointestinal tract tumors and are the third cause of bowel obstruction. Aim: To perform a clinico-pathological correlation of jejunoileal tumors. Patients and Methods: Retrospective revision of medical records of patients operated for a primary jejunoileal tumor in a period of 17 years, excluding duodenal tumors. Results: Twenty four patients were identified, seven had gastrointestinal stromal tumors (GIST), six had a carcinoid tumor and five had lymphomas. GIST predominantly involved distal jejunum and proximal ileum, while carcinoid tumors and lymphomas tended to involve the distal ileum. The main clinical presentation of GIST was gastrointestinal bleeding. Carcinoid tumors presented mostly as bowel occlusion and lymphomas as bowel perforation. Benign lesions tended to present as intussusception. CAT scan and CAT enteroclysis allowed the preoperative diagnosis in 20 patients. Immunohistochemistry was relevant for the pathological diagnosis and radical surgery was the basis of treatment. Prognosis depended on the pathology of the tumor, the degree of malignancy and the tumor stage at the moment of diagnosis. Conclusions: Excluding duodenum, GIST and carcinoid tumors account for 65 percent of primary malignant tumors of jejunum and ileum. Some clues for the diagnosis can be obtained from the clinical picture of the patients.


Objetivo: Establecer una correlación clínico-patológico de los tumores primarios de yeyuno e íleon (Y-I). Pacientes y Método: Revisión retrospectiva que incluye todos los pacientes intervenidos por un tumor primario de Y-I, con exclusión de los tumores de duodeno, en un período de 17 años. Resultados: 24 pacientes, destacando 7 tumores GIST, 6 carcinoides y 5 linfomas. Predominio de sexo masculino (20/4), distribución por edad variable según el tipo de tumor (promedio 55,5 años en los GIST, 64 años en los tumores carcinoides y 50 años en los linfomas). Es llamativo el compromiso del yeyuno y de íleon proximal de los GIST, mientras que los tumores carcinoides y el linfoma afectan de preferencia al íleon terminal. En la presentación clínica predomina la hemorragia digestiva en los GIST, la obstrucción intestinal incompleta en los carcinoides, la perforación en los linfomas, la obstrucción aguda en los adenocarcinomas y la intususcepción en las lesiones benignas. La tomografía computada (TC) y la enteroclisis por TC permitió el diagnóstico preoperatorio en 20 pacientes. La inmunohistoquímica (IHQ) es relevante en el diagnóstico histopatológico de certeza y la cirugía radical con R0 es la base del tratamiento de estas lesiones. El pronóstico depende del tipo histológico, el grado de malignidad y la etapa al momento del diagnóstico. Excluyendo el duodeno, el GIST y los tumores carcinoides representan más de la mitad del global y el 65 por ciento de las neoplasias malignas primarias que afectan el segmento Y-I. Conclusión: A pesar de la rareza y de la heterogeneidad de estos tumores, es posible reconocer una correlación clínico patológica útil en el manejo quirúrgico de los tumores primarios de Y-I.

ABSTRACT

A 60-year-old man was admitted with pain in the abdomen and vomiting for one day; radiography revealed pneumoperitoneum. Laparotomy with excision of ulcer-bearing portion of the jejunum was done. Histology revealed choriocarcinoma with syncytiotrophoblastic and cytotrophoblastic cell differentiation. Postoperatively, urine and serum showed high levels of beta-human chorionic gonadotrophins. The patient expired after an unsatisfactory postoperative course.

ABSTRACT

Jejunal leiomyosarcoma is a rare neoplasm. We report a case of gigantic leiomyosarcoma of the jejunum in a 30-year old man who presented with abdominal distension, pain and constipation. Computerized tomography scan revealed a giant tumor filling the entire abdominal cavity. Fine needle aspiration cytology was suspicious. At laparotomy, a huge jejunal leiomyosarcoma measuring 30 x 25 x 19 cm and weighing 13 kg was completely excised. To the best of our knowledge, this is the first case of a giant jejunal leiomyosarcoma
