ABSTRACT

RESUMEN Las neoplasias mucinosas apendiculares son infrecuentes y se clasifican en neoplasias mucinosas de bajo grado, de alto grado y adenocarcinoma mucinoso. Se consideran precursoras del pseudomixoma peritoneal, caracterizado por la acumulación de mucina dentro de la cavidad abdominal. Informamos tres casos de neoplasia mucinosa apendicular de bajo grado, dos varones y una mujer, que presentaron dolor abdominal agudo, diagnosticados preoperatoriamente mediante tomografía y que fueron manejados con un abordaje laparoscópico (apendicectomía, resección parcial de ciego y colectomía derecha, respectivamente). Los tres casos tuvieron una buena evolución posoperatoria y no hubo complicaciones. Se concluye que las neoplasias mucinosas apendiculares son raras y no tienen una presentación clínica específica. El abordaje laparoscópico es una opción segura y factible. La frecuencia y la duración del seguimiento de estos pacientes es motivo de controversia.


ABSTRACT Appendiceal mucinous neoplasms are rare and are classified in low-grade mucinous neoplasm, high-grade mucinous neoplasm and mucinous adenocarcinoma. They are considered precursors of pseudomyxoma peritonei, characterized by the accumulation of mucin within the abdominal cavity. We report three cases of low-grade appendiceal mucinous neoplasm, two men and one woman, who presented with acute abdominal pain. The diagnoses were made preoperatively by computed tomography scan and the tumors were managed through laparoscopic approach (appendectomy, partial resection of the cecum and right colectomy, respectively). The three patients evolved with favorable postoperative outcome without complications. Appendiceal mucinous neoplasms are rare without specific clinical presentation. The laparoscopic approach is a safe and feasible option. The frequency and duration of surveillance in these patients are still controversial.

ABSTRACT

RESUMEN El vólvulo de ciego involucra al colon derecho proximal, el ciego y el íleon terminal. Se necesitan dos requisitos, una fijación incompleta del ciego y la limitación del movimiento intestinal en un punto fijo que sirve como apoyo y eje para la rotación. Presentamos el caso de una mujer de 52 años que presentó una obstrucción intestinal aguda. Se hizo el diagnóstico preoperatorio con una tomografía y se realizó una colectomía derecha asistida por laparoscopía con anastomosis primaria. En estos pacientes se recomienda la colectomía derecha no oncológica ya que elimina por completo la posibilidad de recurrencia. No se recomienda la colonoscopía, la cecopexia, ni la cecostomía por su alto riesgo de recurrencia y morbimortalidad asociadas.


ABSTRACT Cecal volvulus involves the proximal right colon, the cecum and the terminal ileum. Two requirements are needed, an incomplete fixation of the cecum and the restriction of the bowel movement at a fixed point which serves as a fulcrum for rotation. We present a case of a 52-year-old woman who was admitted with the diagnosis of an acute intestinal obstruction. The preoperative diagnosis was made with a tomography and she underwent a laparoscopic assisted right colectomy with primary anastomosis. In these patients, the right colon nononcologic surgical resection is recommended because eliminates the possibility of volvulus recurrence. Colonoscopy, cecopexy, or cecostomy should be avoided because its associated significant recurrence, morbidity and mortality.
