INDURG TRIAL Protocol: A Randomized Controlled Trial Using Indocyanine Green during Cholecystectomy in Acute Cholecystitis.

INTRODUCTION: Laparoscopic cholecystectomy is one of the most common gastrointestinal surgeries, and bile duct injury is one of its main complications. The use of real-time indocyanine green fluorescence cholangiography allows the identification of extrahepatic biliary structures, facilitating the procedure and reducing the risk of bile duct lesions. A better visualization of the bile duct may help to reduce the need for conversion to open surgery, and may also shorten operating time. The main objective of this study was to determine whether the use of indocyanine green is associated with a reduction in operating time in emergency cholecystectomies. Secondary outcomes are the postoperative hospital stay, the correct intraoperative visualization of the Calot's Triangle structures with the administration of indocyanine green, and the intraoperative complications, postoperative complications and morbidity according to the Clavien-Dindo classification. METHODS: This is a randomized, prospective, controlled, multicenter trial with patients diagnosed with acute cholecystitis requiring emergency cholecystectomy. The control group will comprise 220 patients undergoing emergency laparoscopic cholecystectomy applying the standard technique. The intervention group will comprise 220 patients also undergoing emergency laparoscopic cholecystectomy for acute cholecystitis with prior administration of indocyanine green. CONCLUSION: Due to the lack of published studies on ICG in emergency laparoscopic cholecystectomy, this study may help to establish procedures for its use in the emergency setting.

¿Es segura y eficaz la colecistostomía percutánea en la colecistitis aguda? Análisis de los efectos adversos asociados a la técnica / Is percutaneous cholecystostomy safe and effective in acute cholecystitis? Analysis of adverse effects associated with the technique

IntroducciónEl objetivo principal de nuestro estudio es valorar la seguridad y la eficacia de la colecistostomía percutánea para el tratamiento de la colecistitis aguda determinando la incidencia de efectos adversos que presentan los pacientes sometidos a este procedimiento.Material y métodoEstudio observacional con inclusión consecutiva de todos los pacientes con diagnóstico de colecistitis aguda durante 10 años. La variable principal estudiada ha sido la morbilidad (efectos adversos) recogida de forma prospectiva. Seguimiento mínimo de un año de los pacientes sometidos a colecistostomía percutánea.ResultadosDe 1.223 pacientes ingresados por colecistitis aguda, 66 pacientes han precisado colecistostomía percutánea. El 21% de estos han presentado algún efecto adverso, con un total de 22 efectos adversos. Tan solo 5 de estos efectos, presentados por 5 pacientes (7,6%), han podido ser atribuidos al propio drenaje vesicular. La mortalidad asociada a la técnica es del 1,5%. Tras la colecistostomía un tercio de los pacientes (22 pacientes) han sido sometidos a colecistectomía. Se ha realizado intervención quirúrgica urgente por fracaso del tratamiento percutáneo en 2 pacientes, y diferida en otros 2 pacientes por recidiva del proceso inflamatorio. El resto de los pacientes colecistectomizados han sido intervenidos de forma programada pudiéndose llevar a cabo el procedimiento de forma laparoscópica en 16 pacientes (72,7%) ConclusiónConsideramos la colecistostomía percutánea como técnica segura y eficaz por relacionarse con una baja incidencia de morbimortalidad, debiéndose considerar como alternativa puente o definitiva en aquellos pacientes no tributarios de colecistectomía urgente tras fracaso del tratamiento conservador con antibiótico (AU)

Early discharge in Mild Acute Pancreatitis. Is it possible? Observational prospective study in a tertiary-level hospital.

BACKGROUND AND AIMS: In acute pancreatitis (AP), first 24 h are crucial as this is the period in which the greatest amount of patients presents an organ failure. This suggests patients with Mild AP (MAP) could be early identified and discharged. This is an observational prospective trial with the aim to demonstrate the safety of early discharge in Mild Acute Pancreatitis (MAP). METHODS: Observational prospective study in a third level single centre. Consecutive patients with AP from March 2012 to March 2014 were collected. INCLUSION CRITERIA: MAP, tolerance to oral intake, control of pain, C Reactive Protein <150 mg/dL and blood ureic nitrogen < 5 mg/dL in two samples. EXCLUSION CRITERIA: pregnant, lack of family support, active comorbidities, temperature and serum bilirubin elevation. Patients with MAP, who met the inclusion criteria, were discharged within the first 48 h. Readmissions within first week and first 30 days were recorded. Adverse effects related to readmissions were also collected. RESULTS: Three hundred and seventeen episodes were collected of whom 250 patients were diagnosed with MAP. From these, 105 were early discharged. Early discharged patients presented a 30-day readmission rate of 15.2% (16 patients out of 105) corresponding to the readmission rates in Acute Pancreatitis published to date. Any patient presented adverse effects related to readmissions. CONCLUSION: Early discharge in accurately selected patients with MAP is feasible, safe and efficient and leads to a decrease in median stay with the ensuing savings per process and with no increase in readmissions or inmorbi-mortality.

APC promoter is frequently methylated in pancreatic juice of patients with pancreatic carcinomas or periampullary tumors.

Early detection of pancreatic and periampullary neoplasms is critical to improve their clinical outcome. The present authors previously demonstrated that DNA hypermethylation of adenomatous polyposis coli (APC), histamine receptor H2 (HRH2), cadherin 13 (CDH13), secreted protein acidic and cysteine rich (SPARC) and engrailed-1 (EN-1) promoters is frequently detected in pancreatic tumor cells. The aim of the present study was to assess their prevalence in pancreatic juice of carcinomas of the pancreas and periampullary area. A total of 135 pancreatic juices obtained from 85 pancreatic cancer (PC), 26 ampullary carcinoma (AC), 10 intraductal papillary mucinous neoplasm (IPMN) and 14 chronic pancreatitis (CP) patients were analyzed. The methylation status of the APC, HRH2, CDH13, SPARC and EN-1 promoters was analyzed using methylation specific-melting curve analysis (MS-MCA). Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations were also tested with allele-specific quantitative polymerase chain reaction amplification. Out of the 5 promoters analyzed, APC (71%) and HRH2 (65%) were the most frequently methylated in PC juice. APC methylation was also detected at a high frequency in AC (76%) and IPMN (80%), but only occasionally observed in CP (7%). APC methylation had a high sensitivity (71-80%) for all types of cancer analyzed. The panel (where a sample scored as positive when ≥2 markers were methylated) did not outperform APC as a single marker. Finally, KRAS detection in pancreatic juice offered a lower sensitivity (50%) and specificity (71%) for detection of any cancer. APC hypermethylation in pancreatic juice, as assessed by MS-MCA, is a frequent event of potential clinical usefulness in the diagnosis of pancreatic and periampullary neoplasms.

Cómo afecta el retraso de la colecistectomía tras la pancreatitis aguda litiásicaen la aparición de recidivas. Consecuencias de la falta de recursos / Influence of delayed cholecystectomy after acute gallstone pancreatitis on recurrence. Consequences of lack of resources

Introducción: la pancreatitis aguda es una enfermedad con tendencia a recurrir, sobre todo si persiste la causa que la desencadena. Nuestro objetivo es determinar la tasa de recurrencia de la pancreatitis aguda biliar tras un primer episodio y su intervalo de aparición, así como identificar los factores de riesgo de recidiva. Material y método: hemos incluido todos los pacientes ingresados por un primer episodio de pancreatitis aguda de origen litiásico durante cuatro años. Las variables principales estudiadas fueron reingreso por recurrencia e intervalo de tiempo de aparición del nuevo episodio. Resultados: hemos incluido 296 pacientes que han ingresado en un total de 386 ocasiones. La incidencia de la pancreatitis aguda biliar en nuestro medio es de 17,5/100.000 habitantes/año. El 19,6% de las pancreatitis han sido graves (22,6% de pancreatitis agudas graves en el primer episodio vs. 3,6% en las pancreatitis recurrentes) con una mortalidad global del 4,4%. La tasa global de recurrencia ha sido del 15,5%, con un intervalo de tiempo de 82 días de mediana. El 14,2% de los pacientes han presentado recurrencia después de un episodio de pancreatitis sin que se les hubiera realizado colecistectomía o colangio-pancreatografía retrógrada endoscópica. Las pancreatitis agudas graves recurren un 7,2% mientras que las leves lo hacen el 16,3%, siendo este el único factor de riesgo de recurrencia hallado. Conclusiones: los pacientes ingresados por pancreatitis deberían ser colecistectomizados a la mayor brevedad posible o ser priorizados en la lista de espera. En su defecto, una alternativa a la cirugía podría ser la colangio-pancreatografía retrógrada endoscópica con esfinterotomía en casos seleccionados (AU)

Introduction: Acute pancreatitis is often a relapsing condition, particularly when its triggering factor persists. Our goal is to determine the recurrence rate of acute biliary pancreatitis after an initial episode, and the time to relapse, as well as to identify the risk factors for recurrence. Material and method: We included all patients admitted for a first acute gallstone pancreatitis event during four years. Primary endpoints included readmission for recurrence and time to relapse. Results: We included 296 patients admitted on a total of 386 occasions. The incidence of acute biliary pancreatitis in our setting is 17.5/100,000 population/year. In all, 19.6% of pancreatitis were severe (22.6% of severe acute pancreatitis for first episodes versus 3.6% for recurring pancreatitis), with an overall mortality of 4.4%. Overall recurrence rate was 15.5%, with a median time to relapse of 82 days. In total, 14.2% of patients relapsed after an acute pancreatitis event without cholecystectomy or endoscopic retrograde cholangio-pancreatography. Severe acute pancreatitis recur in 7.2% of patients, whereas mild cases do so in 16.3%, this being the only risk factor for recurrence thus far identified. Conclusions: Patients admitted for pancreatitis should undergo cholecystectomy as soon as possible or be guaranteed priority on the waiting list. Otherwise, endoscopic retrograde cholangio-pancreatography with sphincterotomy may be an alternative to surgery for selected patients (AU)

Solitary fibrous tumor of the liver. Case report and review of the literature.

Solitary fibrous tumor (SFT) is a rare mesenchymal tumor. Given its origin, it can appear in almost any location. In the literature, only 50 cases of SFT in the liver parenchyma have been reported. Despite its rarity, this entity should be included in the differential diagnosis of liver masses. We report the first case with imaging data from five years prior to diagnosis, which was treated by right portal embolization and arterial tumor embolization, and subsequent liver resection. We also present an exhaustive review of the cases described to date.

[Bile duct cysts in adults: surgical procedure]. / Quistes de los conductos biliares del adulto: estrategia quirúrgica.

OBJECTIVE: The reported prevalence rate of bile duct cysts is very low. However, the clinical presentation of bile duct cysts is common to other hepatobiliary diseases. In this article, we report on a series of patients who have been surgically treated over the last 15 years. MATERIAL AND METHOD: All the patients who had undergone bile duct cyst-related surgery at this hospital had their clinical history reviewed retrospectively from 1990 to 2002. Data were obtained prospectively from 2002 to 2005. The following variables were taken into account in our analysis: diagnosis data, surgical procedure, morbidity, post-surgery mortality rates, and follow-up. RESULTS: Over the last 15 years, 18 patients have undergone surgery at our hospital (6 male, 12 female). The most common clinical presentation was that of abdominal pain and the usual symptoms associated with acute cholangitis. As for surgical procedure, a complete cyst resection with biliary derivation was performed in all 15 cases. The histopathological diagnosis was choledochal cyst in 12 cases, Caroli's disease in 5 cases and a malignant choledochal cyst (adenocarcinoma) in 1 case. The most frequent post-surgical complication was bile leak (3 cases, 16.6%). There was no post-surgical mortality (0%). There were no relapses in the subsequent follow-up CONCLUSIONS: Our preferred surgical procedure is that of complete cyst resection with biliary derivation. Our overall results are similar to those of medical teams who practise a radical resective procedure, and better than those who practise partial resections.

Quistes de los conductos biliares del adulto: estrategia quirúrgica / Bile duct cysts in adults: surgical procedure

Introducción. Los quistes de los conductos biliares son una enfermedad muy poco prevalente. Sin embargo, su presentación clínica es común a la de otros procesos biliopancreáticos. Presentamos nuestra serie de pacientes intervenidos en los últimos 15 años. Material y método. Se han revisado retrospectivamente las historias clínicas de los pacientes intervenidos por esta enfermedad, en nuestro hospital, entre 1990 y 2002. A partir de 2002, se toman los datos de forma prospectiva hasta 2005. Se han analizado variables de métodos de diagnóstico, técnica quirúrgica, morbilidad y mortalidad postoperatoria y seguimiento posterior. Resultados. En los últimos 15 años se ha intervenido a 18 pacientes (6 varones, 12 mujeres). La presentación clínica más común ha sido el dolor abdominal, seguido del cuadro clínico de colangitis aguda. La técnica quirúrgica ha sido resección total del quiste + derivación biliodigestiva en el 100% de los casos. El diagnóstico anatomopatológico ha sido de quiste coledocal en 12 casos, enfermedad de Caroli en 5 casos, quiste coledocal malignizado (adenocarcinoma) en 1 caso. La complicación postoperatoria más frecuente ha sido la fístula biliar (3 casos, 16,6%). La mortalidad postoperatoria ha sido del 0%. En el seguimiento tardío, no se ha evidenciado recidiva del quiste en ningún caso (0%). Conclusiones. El tratamiento quirúrgico de elección es la resección total del quiste con derivación biliodigestiva. Nuestros resultados son equiparables a los de los equipos que practican una técnica de resección radical y, a su vez, son mejores que los de las series que practican resecciones parciales (AU)
