Delayed intestinal obstruction due to posttraumatic diaphragmatic hernia.

BACKGROUND: Diaphragmatic rupture can be missed during trauma diagnosis. Different pressures between the thorax and the abdomen allow the abdominal viscera to herniate into the chest cavity. Cardiorespiratory and abdominal symptoms may appear later due to passive compression and incarceration, respectively. CLINICAL CASE: We report the case of a 52-year-old female with abdominal pain and vomiting. Chest x-ray demonstrated an elevation of the right hemidiaphragm, and computed tomography showed herniation of small bowel and colon into the chest cavity with dilated small bowel due to a diaphragmatic hernia. CONCLUSIONS: History of traumatic events should be considered with high suspicion in the diagnostic process to avoid delayed diagnosis of this condition. The nonspecific symptoms of this condition often lead the patient to consult different specialists. A multidisciplinary approach is required and aimed at preventing an unnecessary increase of morbidity and mortality.

Proximal-type epithelioid sarcoma in pubis. Case report and review of the literature.

BACKGROUND: The "proximal-type" epithelioid sarcoma (PES) is a rare variant of conventional epithelioid sarcoma. It has been described in older patients in the proximal portion of the extremities with a predilection for the pelvis and perineum. It is clinically more aggressive, showing a higher incidence of recurrence, metastasis, resistance to chemotherapy and a higher mortality. We report the case of a patient with a PES of the pubic region and we review the previous literature. CLINICAL CASE: We report the case of a 57-year-old female with a painless, progressively growing mass in the region of the pubis. We performed surgical resection of the lesion with clear margins and histological and immunohistochemical study allowed the definitive diagnosis of PES. After 4 disease-free years, the patient had a tumor recurrence at the same location. We performed en bloc resection of the lesion and immunohistochemical study confirmed the recurrence of PES. The patient refused adjuvant therapy. Today, after 4 years of follow-up, the patient remains asymptomatic and without evidence of recurrence or distant disease. CONCLUSIONS: Diagnosis of PES is complex because histological findings may be confused with multiple tumors; therefore, immunohistochemical study is definitive. PES shows positivity for epithelial markers (cytokeratin and EMA), mesenchymal markers (vimentin) as well as CD34. According to what has been reported in the literature, surgical treatment with free margins is indicated, with adjuvant therapies when the risk of recurrence is high.

Colecistectomía laparoscópica de puerto único en un programa de CMA / Single port laparoscopic cholecystectomy in major ambulatory surgery (MAS)

Introducción: La cirugía endoscópica por orificios naturales es una nueva modalidad quirúrgica en fase de desarrollo. La vía más natural para los cirujanos es usar una cicatriz ya existente como es el ombligo. La reciente introducción de trocares diseñados para este fin ha hecho posible su puesta en práctica. Material y métodos: En este estudio presentamos nuestra experiencia preliminar en la colecistectomía laparoscópica con puerto de acceso único umbilical, mediante un estudio prospectivo que incluye a 26 pacientes intervenidos entre enero 2009 y enero 2010. También pretendemos conocer su posible realización en régimen de CMA. Resultados: Todos los pacientes presentaban colelitiasis no complicadas, aunque en 5 se identifico una colecistitis en la cirugía. El tiempo quirúrgico promedio fue de 51,2min. La estancia hospitalaria media fue 25,7h. En el 76,92% de los pacientes el ingreso fue menor de 24h. No hubo ningún reingreso ni complicación intraoperatoria o postoperatoria importante. Conclusiones: A la vista de nuestros resultados la colecistectomía laparoscópica por puerto único favorece su inclusión en un programa de cirugía mayor ambulatoria (AU)

Introduction: Natural orifice endoscopic surgery is a new surgical procedure still in the development phase. The most natural entry for surgeons is to use an already existing scar, such as the navel. The recent introduction of trocars designed for this purpose has made it possible to put this into practice. Material and methods: We present our preliminary experience in single trans‐umbilical incision laparoscopic cholecystectomy, by means of a prospective study which included 26 patients operated on between January 2009 and January 2010. We also attempt to find out whether it can be performed in a MAS programme. Results: All patients had uncomplicated cholelithiasis, although in 5 of them cholecystitis was identified during the surgery. The mean surgical time was 51.2min. The mean hospital stay was 25.7h, and 76.92% of patients were admitted for less than 24h. There were no re-admissions or significant intra-operative or post-operative complications. Conclusions: On looking at our results, single port laparoscopic cholecystectomy could be included in a major ambulatory surgery programme (AU)
