Intracholecystic papillary neoplasm: potential differential diagnosis before a gallbladder polyp.

Intracholecystic papillary neoplasia (IPN) is a rare entity rarely described in the literature, of incidental anatomopathological diagnosis in a cholecystectomy specimen that presents a premalignant behavior, with progression to carcinoma in more than 50% of cases. In the absence of an invasive component, clinical follow-up is recommended, without associating another surgical gesture, with a 5-year prognosis (90% survival). We present a case of a patient with an incidental diagnosis of NPIC after laparoscopic cholecystectomy due to presenting a gallbladder polyp.

Rendimiento del stent en el manejo de la obstrucción intestinal por cáncer de colon izquierdo. Estudio ambispectivo y unicéntrico / Stent performance in obstructive left colon cancer. Unicentric and cross-sectional study

Objetivo: Evaluar la eficacia, seguridad y resultados clínicos y oncológicos del stent colónico en la estrategia terapéutica inicial de la obstrucción intestinal por cáncer de colon izquierdo. Métodos: Estudio descriptivo y ambispectivo (2008-2018) de pacientes con diagnóstico clínico y radiológico de obstrucción neoplásica de colon izquierdo en los que se indicó colocación de stent, analizando los grupos de stent paliativo, stent como puente a cirugía y cirugía urgente por fallo o complicaciones del stent. Resultados: El estudio incluyó a 208 pacientes. La tasa de éxito técnico y clínico fue del 82,2 y del 74,5%, respectivamente, con perforación asociada en el 4,3% de la muestra. En el 32,2% el stent se comportó como puente a cirugía, mientras que el 28,4% de los pacientes precisaron intervención quirúrgica urgente. En el 39,4% el stent fue colocado con intención paliativa. La proporción de cirugía laparoscópica, resección oncológica, anastomosis primaria y ganglios obtenidos fue superior en los pacientes intervenidos mediante cirugía electiva frente a la urgente, con menor estancia postoperatoria y orbimortalidad postoperatoria grave. Los pacientes en estadio II-III con resección tumoral oncológica intervenidos de forma programada presentaron mayor supervivencia que aquellos intervenidos de urgencia (p = 0,001). Conclusiones: El tratamiento de la oclusión neoplásica de colon izquierdo mediante stent supone una estrategia eficaz para operar de forma electiva un número importante de pacientes y evita la colostomía en pacientes paliativos, aunque las complicaciones o el fracaso de la técnica conllevan cirugía urgente en casi un tercio de los pacientes

Objective: To evaluate the efficacy, safety and clinical and oncological results of colonic stents in the initial therapeutic strategy of obstructive left colon cancer. Methods: Descriptive and ambispective study (2008-2018) of patients with clinical and radiological diagnosis of neoplastic obstruction of the left colon in whom a colonic stent was indicated, analyzing the following groups: palliative stent, stent as bridge to surgery and urgent surgery in case of stent failure or complications. Results: The study included 208 patients. The technical and clinical success rates were 82.2% and 74.5%, respectively, with associated perforation in 4.3% of the sample. In 32.2%, the stent was placed as bridge to surgery, while 28.4% required urgent surgical intervention. The stent was placed with palliative intent in 39.4%. The proportion of laparoscopic surgery, oncological resection, primary anastomosis and lymph nodes resected were higher in patients undergoing elective surgery than in urgent surgery, with shorter postoperative stay and less severe postoperative morbidity and mortality. Stage II-III patients with oncological tumor resection who underwent elective surgery had increased survival compared to those who underwent urgent surgery (P = 0.001). Conclusions: Initial treatment of neoplastic obstruction of the left colon with a stent is an effective strategy in elective surgery and avoids permanent colostomy in palliative patients, although complications or stent failure lead to urgent surgery in almost one-third of patients

Ecografía y Escala de Alvarado en el diagnóstico de la apendicitis aguda. Impacto en la tasa de apendicectomía negativa / Ultrasonography and the Alvarado score in the diagnosis of acute appendicitis: impact on the negative appendectomy rate

Objetivo: Establecer la tasa de apendicectomía negativa (TAN) y evaluar las diferencias entre la Escala de Alvarado y la ecografía abdominal en los pacientes con apendicitis aguda (AA) y aquellos con apendicectomía negativa. Método: Estudio descriptivo, retrospectivo de corte transversal. Se recogieron los pacientes intervenidos de urgencia bajo sospecha de AA durante un año en un hospital de tercer nivel. Resultados: Se incluyeron 225 pacientes. La TAN fue de 7,11%. Una puntuación en la Escala de Alvarado mayor o igual de 5 obtuvo una odds ratio (OR) de 7,46 (p = 0,0002) para padecer AA, con una sensibilidad del 94,2%. La ecografía compatible con AA obtuvo una OR 3,58 (p = 0,0125) y una TAN del 5%. Conclusiones: La elevada sensibilidad de la Escala de Alvarado para puntuación mayor o igual de 5 hace aconsejable su aplicación en todo paciente que acude al Servicio de Urgencias con dolor en la fosa iliaca derecha. Puntuaciones mayores o iguales a 7 disminuyen la TAN hasta el 3%. La ecografía abdominal es una prueba rápida y barata con una TAN baja (AU)

Objective: To establish the negative appendectomy rate (NAR) after patients with acute abdomen were evaluated with the Alvarado score and compare it to the NAR in patients evaluated with abdominal ultrasound. Methods: Cross-sectional, retrospective, descriptive study in patients who underwent emergency surgery for suspected acute appendicitis in a tertiary-care hospital over a period of 1 year. Results: A total of 225 patients were included. The NAR was 7.11% for the series. An Alvarado score of 5 or more had an odds ratio (OR) of 7.46 (P=.0002) for acute appendicitis; sensitivity was 94.2%. Ultrasound findings consistent with acute appendicitis had an OR of 3.58 (P=.0125) for the diagnosis; the NAR was 5%. Conclusions: The high sensitivity of an Alvarado score of 5 or more supports using this tool to evaluate all patients who come to the emergency department with pain in the right iliac fossa. With scores of 7 or more the NAR falls to 3%. Abdominal ultrasound is a rapid, inexpensive diagnostic procedure associated with a low NAR (AU)
