Solid pseudopapilar neoplasm of the pancreas.

Solid pseudopapillary tumor of the pancreas is a rare entity, more frequent in women between the 2nd and 4th decades. The diagnosis is usually incidental and it can be reached by computed tomography or magnetic resonance imaging. Subsequent pathological confirmation is necessary for an adequate treatment. A retrospective study of six cases was carried out. All the patients were female, between 14 and 56 years of age, in which 50% the tumor were an incidental finding. We had three cases located in the head and three in the body of the pancreas. We performed three pancreaticoduodenectomies and three distal pancreatectomies with splenic preservation, without disease recurrence.

El tumor sólido-quístico de páncreas es poco frecuente y predomina en mujeres entre la segunda y la cuarta décadas de la vida. Los pacientes son generalmente asintomáticos. El diagnóstico se realiza por imágenes con tomografía o resonancia magnética, y con la posterior confirmación patológica para poder ofrecer un tratamiento adecuado. Presentamos una serie de seis casos. Todas las pacientes fueron de sexo femenino, de entre 14 y 56 años. El 50% fueron un hallazgo incidental. Tuvimos tres casos localizados en la cabeza y tres en el cuerpo del páncreas. Se realizaron tres duodenopancreatectomías cefálicas y tres pancreatectomías distales con preservación esplénica, con buena evolución y sin recidiva.

Intramural esophageal bronchogenic cyst.

ANTECEDENTES: Los quistes broncogénicos esofágicos son sacos cerrados originados de brotes anormales del tubo -traqueobronquial primitivo. Estas lesiones suelen ser asintomáticas, por lo que pueden hallarse incidentalmente o pueden causar síntomas por compresión de estructuras adyacentes. Son lesiones muy poco comunes; se han publicado unos 23 casos en adultos. CASO CLÍNICO: Presentamos el caso de un varón de 44 años con un cuadro de tos de larga duración, sin otro síntoma. Para descartar las causas más comunes de sus síntomas se realizan estudios que objetivan la presencia de una lesión intramural de 40 × 43 mm. Se realiza videotoracoscopia para su resección y estudio, resultando ser un quiste broncogénico. BACKGROUND: Bronchogenic cysts are close sacks originated from abnormal development of the tracheobronchial tree. These lesions are usually asymptomatic or can cause symptoms, by compression of adjacent structures. This pathology is so unusual that there are only about 23 cases published in adults. CASE REPORT: We report a case of a 44 year-old man with persistent cough, without other symptom. The most common causes for his symptoms were ruled out, so imaging studies were made, showing at the medial portion of the esophagus, located intramural a 40 × 43 mm ovoid lesion. Resected by video-assisted thoracoscopy for its study. With findings attributable to bronchogenic cyst.

Short-term and oncological outcomes in laparoscopic colectomy in colon cancer stage I-III with 3-year follow-up.

BACKGROUND: Laparoscopic colectomy (LC) presents similar short-term results and oncological outcomes to conventional colectomy (CC) in colon cancer. OBJECTIVES: Compare short-term and oncological outcomes at 3-year follow up between LC and CC. MATERIALS AND METHODS: Patients who underwent LC and CC for colon cancer between January 2010 and December 2017 were retrospectively analyzed. Short-term results and oncological outcomes were studied. RESULTS: Two hundred sixty-nine patients were included in the study. CC was performed in 37.5% and LC in 62.5%. LC presented shorter operative time (157 vs. 175 min, p = 0.01), shorter length of stay (8.4 vs. 10.5 days, p = 0.02), lees readmission (6% vs. 15%, p = 0.02), and lower morbidity (40% vs. 56%, p = 0.01). No differences were found for overall survival (OAS) (LC = 87.1% vs. CC = 82.8%, p = 0.28) and disease-free survival (DFS) (LC = 78.2% vs. CC = 75.3%, p = 0.47). Recurrence was observed in 37 patients (LC = 16.1% vs. CC = 18.3%, p = 0.53). No differences were found for local recurrence (LC = 6.5% vs. CC = 8.6%, p = 0.49) and distant recurrence (LC = 12.1% vs. CC = 16.1%, p = 0.3). Stage analysis showed no difference for recurrence, OAS, and DFS. CONCLUSIONS: LC is a safe procedure with short-term outcomes, OAS, DFS, and recurrence similar to CC. LC should be the initial indication in non-metastatic colon cancer in our population.

ANTECEDENTES: La colectomía laparoscópica (CL) presenta resultados a corto plazo y oncológicos similares a los de la colectomía convencional (CC) en cáncer de colon. OBJETIVO: Comparar los resultados a corto plazo y oncológicos a 3 años de seguimiento entre la CL y la CC. MATERIAL Y MÉTODOS: Pacientes intervenidos de CL y CC por cáncer de colon entre enero de 2010 y diciembre de 2017. Se estudiaron los resultados a corto plazo y oncológicos. RESULTADOS: Se incluyeron 269 pacientes (62.5% CL y 37.5% CC). La CL presentó menor tiempo quirúrgico (157 vs. 175 min; p = 0.01), menor estadía hospitalaria (8.4 vs. 10.5 días; p = 0.02), menor reinternación (6% vs. 15%; p = 0.02) y menor morbilidad (40 vs. 56%; p = 0.01). No se observan diferencias para sobrevida global (87.1% CL y 82.8% CC; p = 0.28) y sobrevida libre de enfermedad (78.2% CL y 75.3% CC; p = 0.47). Hubo recidiva en 37 pacientes (16.1% CL y 18.3% CC; p = 0.53). No se encontraron diferencias en recidiva local (6.5% CL y 8.6% CC; p = 0.49), a distancia (12.1% CL y 16.1% CC; p = 0.3), al dividir la recidiva, la sobrevida global y la sobrevida libre de enfermedad por estadios. CONCLUSIONES: La CL es un procedimiento seguro, con una sobrevida global, una sobrevida libre de enfermedad y una tasa de recidiva similares a las de la CC. La CL debería ser la indicación inicial en el cáncer de colon no metastásico en nuestra población.
