RESUMO
Acute appendicitis is the most common surgical abdominal pathology worldwide that requires immediate intervention. We report a 78-year-old patient who presented with acute appendicitis. A computed tomography (CT) of the abdomen and pelvis showed acute appendicitis due to appendiceal orifice obstruction from a migrated biliary stent. The condition was successfully treated nonoperatively with endoscopic stent removal, allowing his discharge 72 hours after his admission.

Ischiorectal fossa tumors are rare lesions, mostly described in case reports or case series. These lesions represent a diagnostic and therapeutic challenge. Hence, an appropriate preoperative study and multidisciplinary discussion are essential to achieve good oncologic and functional results. We report a case of a 73-year-old male operated on five years before in another health center due to the diagnosis of a left gluteal tumor. The lesion was excised, and biopsies confirmed a high-grade epithelioid sarcoma with a close margin, requiring a subsequent wider excision of the surgical margins. The patient received adjuvant radiotherapy. After four years of follow-up, the patient developed mild pain with skin retraction around the former incision. A local recurrence was diagnosed by imaging. In a multidisciplinary team meeting, a decision to resect the lesion with preservation of the anus and the pelvic floor was taken. The patient underwent a laparoscopic defunctioning loop ileostomy and a resection of the recurrent tumor in the ischiorectal fossa with preservation of the anal sphincter. The defect was covered utilizing a superior gluteal artery perforator flap and a partial gluteus maximus muscle rotation. The tumor was completely excised with negative margins. The patient was discharged without complications after 25 days due to flap management. After one year of follow-up, the patient is recurrence-free, and the ileostomy was closed.

La apendicitis aguda es la patología quirúrgica abdominal más común alrededor del mundo. Presentamos un caso de un paciente de 78 años que se presentó con un cuadro de apendicitis aguda en el servicio de urgencias. La tomografía computada de abdomen y pelvis mostró una apendicitis aguda secundaria a la obstrucción del orificio apendicular por una prótesis biliar migrada. Se realizó un manejo exitoso mediante el retiro de la prótesis por colonoscopía, permitiendo el alta hospitalaria del paciente 72 horas posteriores al ingreso.

RESUMO
Los tumores de la fosa isquiorrectal son poco frecuentes, habitualmente descritos en reportes o series de casos. Estas lesiones son un reto terapéutico, requiriendo un estudio preoperatorio apropiado, además de discusión y manejo guiado por un comité multidisciplinario, que permiten lograr resultados óptimos tanto oncológicos como funcionales. Presentamos un caso de un hombre de 73 años con antecedentes de resección de un tumor glúteo izquierdo en otro centro 5 años antes. La biopsia fue compatible con un sarcoma epiteloideo (SE) de alto grado, con margen quirúrgico < 0,5 mm que requirió ampliación de los márgenes posteriormente. Además, se realizó radioterapia adyuvante. Al cuarto año de seguimiento el paciente desarrolla dolor e induración con retracción en relación a cicatriz quirúrgica, siendo objetivada una recidiva tumoral local. Luego de una discusión multidisciplinaria, se realizó una desfuncionalización con ileostomía en asa laparoscópica y resección tumoral con preservación del ano y del piso pélvico. El defecto fue cubierto por el equipo de cirugía plástica utilizando un colgajo perforante de la arteria glútea superior. La biopsia confirmó la recidiva tumoral y los márgenes quirúrgicos fueron negativos. El paciente es dado de alta a los 25 días postoperatorios por cuidados del colgajo, sin complicaciones. Al año de seguimiento el paciente no presenta recidiva tumoral, la ileostomía fue cerrada, y sus resultados funcionales en términos defecatorios y de la herida son buenos.

RESUMO
Introduction: Bibliometric works aim to collect and to do a quantitative analysis of the scientific production. In Chile there are no studies that characterize neurosurgical scientific production. The objective of this study is to describe the free submission presented at the last four National Congress of the Society of Neurosurgery of Chile. Materials and Methods: The abstracts books of each year National Congress of Chilean Society of Neurosurgery were reviewed between the year 2010 and 2013. Results: A total of 251 free submissions were presented, and were filiated 354 participations of 51 different institutions. The 73,1 percent of the institutions named in the different submissions came from the Metropolitan Region. The most - named hospital group was the Institute of Neurosurgery Dr. Alfonso Asenjo with a 19,2 percent(68), while the most - named University was Pontificia Universidad Católica de Chile with a 6,5 percent(23). The most common topic was tumor and vascular neuropathology with a 29,4 percent(74) and 21,1 percent(53) respectively. Discussion and Conclusions: We noticed that the majority of submissions involves one institution, with an average of 1,4 institutions per free submission, this might be explained because uncompleted filiations of authors. We can see a clear centralization of the origin of the different submissions. The two more representative areas of investigation in these congresses were tumor and vascular neuropathology. We think that is necessary to create a common protocol for registration and filiations of free submissions in the different congresses to create a National database.
