RESUMEN
Peritoneal cancer is the invasion by malignant cells of serous membrane that lines the abdominal cavity, the viscera, and the coelom of the amniotes. Histologically, it is indistinguishable from ovarian counterpart, although in the former, it commonly involves the ovary only superficially, or it may totally lack an ovarian component, but with extensive involvement of the peritoneum, calcified perihepatic peritoneal nodules, or involvement of the omentum, in most cases. The current study describes the case of a 54-year-old female patient referring a history of colitis and dairy intolerance. A transvaginal ultrasound and a computed tomography (CT) scan revealed a tumor measuring 70 × 61 × 63 mm. CA-125 serum levels were 880 U/ml. Laparotomy surgery was indicated, and tumor was found at the level of the rectovaginal septum without evidence of metastasis. Tumor dissection and protective colostomy with loop sigmoid colon were performed. A pathological study gave a diagnosis of a high-grade peritoneal serous carcinoma with a micropapillary pattern. The present study describes the case of papillary serous peritoneal cancer presented as a single tumor mass without extensive involvement of the peritoneum. Additionally, the need for routine tests for its diagnosis and documenting hormonal alterations as the cause of its origin are suggested.
RESUMEN
Resumen: Las dilataciones biliares son malformaciones congénitas raras que pueden involucrar la totalidad de la vía biliar, más comunes durante la primera década de la vida. La mayoría de los casos se presentan con dolor abdominal crónico localizado en cuadrante superior derecho e ictericia. La alta sospecha clínica acompañada de estudios de imagen son indispensables para el diagnóstico. El tratamiento ha evolucionado hasta que en la actualidad la resección completa de los quistes se ha convertido en el manejo de elección, ya que presenta buena respuesta, aunque sin quedar exentos de complicaciones a largo plazo. Presentamos el caso de un paciente del sexo masculino, de 27 años de edad, con historia de dolor abdominal epigástrico de 3 meses de evolución, diagnosticado como quiste de colédoco Todani IVa por resonancia magnética. Se realizó manejo quirúrgico abierto con resección total del quiste y derivación biliodigestiva en Y de Roux sin complicaciones. Fue egresado a los 7 días postoperatorios sin eventualidades. Se realizó revisión de la literatura enfocada en el abordaje y manejo quirúrgico de casos similares.
Abstract: Biliary tree dilations are unusual congenital malformations that may involve the entire bile circulation and they are common during the first life decade. Most cases initiate with jaundice and chronic abdominal pain which localizes in right upper quadrant. High clinical suspicion accompanied by imaging studies are essential for diagnosis. Treatment has evolved until today complete cyst resection has become the treatment of choice, since it presents a good response, although without being free from long-term complications. We present the case of a 27-year-old male patient with a history of 3 months onset epigastric abdominal pain diagnosed as Todani IVa common bile duct choledochal cyst by magnetic resonance imaging. Open surgical management was performed with total resection of the cyst and biliodigestive Roux-en-Y diversion without any complications. He was discharged 7 days post-op. A review of the literature focused on the surgical approach and management of similar cases was carried out.
