RESUMENEl íleo biliar es una complicación rara de la litiasis biliar que ocurre en apenas el 0,1% de estos pacientes y supone el 1-6% del total de las oclusiones intestinales mecánicas del adulto. Se presenta un caso clínico de íleo biliar de localización colónica en un paciente de 45 años de edad, colecistectomizado hace 4 años, que ingresa a nuestra institución con el diagnóstico de oclusión intestinal intermitente. Tras un tratamiento inicial conservador con buena evolución durante las primeras 48 h, presenta posteriormente un agravamiento de su cuadro clínico. Se decide laparotomía exploradora con resección de colon sigmoides y anastomosis término-terminal con colostomía transversa de derivación. En el examen de la pieza se objetiva cálculo biliar de 3 cm de diámetro impactado en el colon sigmoides. Debido a lo excepcional de esta patología y los pocos reportes internacionales existentes en pacientes colecistectomizados, nuestro objetivo es poner en consideración este caso clínico y su correspondiente revisión de la literatura.PALABRAS CLAVE: Ileo biliar, fístula biliar, cálculos biliares. ABSTRACTBiliary ileus is an uncommon complication of biliary stones and accounts for 1 to 6% of all mechanical intestinal obstructions in the adult. We report a 45 years old male, subjected to a cholecystectomy four years earlier, admitted with the diagnosis of intermittent intestinal obstruction. Due to a bad evolution with medical treatment, he was subjected to an exploratory laparotomy and sigmoid colon was excised. A latero-terminal anastomosis and a transverse colostomy were done. The examination of the surgical piece showed the presence of a 3 cm diameter biliary stone impacted in the sigmoid colon.

RESUMENLa paniculitis mesentérica es una enfermedad inflamatoria del tejido adiposo del mesenterio, de presentación infrecuente y que se caracteriza, por el engrosamiento, endurecimiento y nodularidad del mismo. Se pone en consideración un caso clínico en un varón joven, con una forma de presentación poco común que requirió de laparotomía exploradora para realizar el diagnóstico y tratamiento. ABSTRACTWe report a 28 years old obese male presenting with abdominal pain of increasing intensity lasting 15 days. In the last days, diarrhea and fever appeared. On abdominal examination a 8 cm painful mass was palpated. An abdominal ultrasound showed an anechoic mass in the epigastrium. An abdominal CAT scan showed an inflammatory mass that involves the small bowel. The patient is subjected to a percutaneous needle aspiration, obtaining 50 ml of a purulent fluid. Due to persistence of fever, the patient was operated finding an inflammation that involved the mesentery and the great omentum and covering abscess. The pathologic study of the surgical piece reported a unspecific nodular mesenteric panniculitis KEY WORDS: Mesenteric panniculitis, abscess.

RESUMENEl Tumor Desmoide o Fibromatosis Mesentérica es una enfermedad infrecuente en la que se reconocen 2 formas: una esporádica y otra asociada a poliposis familiar adenomatosa. De etiología desconocida, su diagnóstico preoperatorio es dificultoso y el tratamiento de elección es quirúrgico. Se pone en consideración un caso de esta entidad en un varón joven, que se presentó con dolor abdominal y fiebre. Se realizó cirugía resectiva agresiva, otorgándose el alta a los 18 días de la intervención.PALABRAS CLAVE: Tumor Desmoides, fibromatosis agresiva, fibromatosis abdominal. ABSTRACTDesmoid tumor or mesenteric fibromatosis is an uncommon disease with to variants: a sporadic form and one associated to familial adenomatous polyposis. Surgery is the treatment of choice. We report a 45 years old male presenting with abdominal pain and fever. An abdominal ultrasound informed the presence of a mass in the periumblical area. An Abdominal CAT scan showed a 13 cm diameter solid mass located in the left upper quadrant. The patient was operated and that mass is excised, requiring also a hemicolectomy, excision of the fourth portion of the duodenum and cholecystectomy. The pathology report of the excised tumor informs a mesenteric fibromatosis. The patient was discharged at the 18th postoperative day.

Umbilical mesh hernia repair. Experience in 60 patientsBackground: There is a lack of consensus on the best technique umbilical for hernia repair and several options have been use. The systematic use of prostheses is currently recommended. Aim: To evaluate the treatment of umbilical hernias with a mesh and assess the placement of a prosthetic cone as an alternative. Materials and Methods: We evaluated prospectively the surgical procedures in 60 patients with umbilical hernia aged 30 to 86 years (40 females). We excluded surgical procedures in which a mesh was not used and those performed as emergencies. When the hernia ring was of less than 3 cm in diameter, a polypropylene cone or plug was placed. A preperitoneal mesh technique was used when rings were larger. Results: Forty five patients had a ring of less than 3 cm. Among these, a polypropylene cone or plug was placed in 30 and 15 patients, respectively. A mesh was placed in the remaining patients. As surgical complications, one patient had a hematoma (1.6%) and three patients had seromas (5%). There were no surgical site infections or hernia relapse. Conclusions: Umbilical hernia repair using with polypropylene prostheses is a safe and easy to implement technique.
