Estudio de minimización de costes hospitalarios en el tratamiento de la coledocolitiasis / Minimising hospital costs in the treatment of bile duct calculi: A comparison study

Introducción El tratamiento de la coledocolitiasis asociada a colelitiasis es controvertido. Los costes hospitalarios podrían ser un factor decisivo para elegir entre las distintas opciones terapéuticas. Objetivos Comparar la eficacia y los costes de 2 alternativas en el tratamiento de la coledocolitiasis: 1) Un-tiempo: colecistectomía y exploración de la vía biliar por laparoscopia y 2) Dos-tiempos: colangiopancreatografía retrógrada endoscópica y colecistectomía laparoscópica secuencial. Material y métodos Estudio observacional, retrospectivo de 49 pacientes con coledocolitiasis y vesícula in situ, tratados de forma consecutiva y simultánea durante 2 años, mediante una de las 2 estrategias. Se compararon las complicaciones postoperatorias, estancia, número de procedimientos por paciente, conversión a laparotomía, eficacia en la extracción de cálculos y costes hospitalarios. Resultados No hubo diferencias en cuanto a características clínicas y morbilidad de los pacientes. La estancia postoperatoria media para el grupo Un-tiempo fue menor que para el grupo Dos-tiempos. Tres pacientes del grupo Dos-tiempos requirieron conversión a laparotomía. La mediana de costes por paciente fue menor para la estrategia en Un-tiempo, representando un ahorro global de 37.173€ durante el período estudiado. Conclusiones Entre las 2 opciones terapéuticas, no se han encontrado diferencias significativas en cuanto a la eficacia, ni la morbimortalidad postoperatorias, pero sí desde el punto de vista de la estancia y los costes hospitalarios. El manejo de los pacientes con coledocolitiasis en un solo tiempo representó un ahorro de 3 días de estancia y 1.008€ por paciente (AU)

Introduction The treatment of bile duct calculi associated with cholelithiasis is controversial. The hospital costs could be a decisive factor in choosing between the different therapeutic options. Objectives To compare the effectiveness and costs of two options in the treatment of common bile duct calculi: 1) One-stage: Laparoscopic cholecystectomy and bile duct exploration, and 2) Two-stage: sequential endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy. Material and methods A retrospective, observational study was performed on 49 consecutive patients with bile duct calculi and gallbladder in situ, treated consecutively and simultaneously over a two year period. The post-operate complication, hospital stay, number of procedures per patient, conversion to laparotomy, efficacy of removing the calculi, and hospital costs. Results There were no differences as regards the patient clinical features or morbidity. The mean post-surgical hospital stay for the One-stage group was less than that in the Two-stage group. Three patients of the Two-stage group required conversion to laparotomy. The median costs per patient were less for the One-stage strategy, representing an overall saving of 37,173€ during the period studied. Conclusions No significant differences were found between the two treatment options as regards efficacy or post-surgical morbidity and mortality, but there were differences in hospital stay and costs. The management of patients with gallstones in one-stage surgery represents a saving of 3 days hospital stay and 1,008€ per patient (AU)

[Supercharged ileocoloplasty: an option for complex oesophageal reconstructions]. / Ileocoloplastia supercharged: una opción para reconstrucciones esofágicas complejas.

INTRODUCTION: Oesophageal reconstruction in a second time is a complex surgical operation which, in some cases, requires combining microvascular techniques to increase vascular flow to the conduit. "Supercharged" ileocoloplasty allows creation of a longer conduit that makes it possible to replace the entire oesophagus. We describe our initial experience with this technique for the total reconstruction of the oesophagus. MATERIAL AND METHODS: A retrospective review of the period from October 2007 to December 2009 identified 4 patients on whom a deferred oesophageal reconstruction was performed with a "supercharged" ileocoloplasty. The indications of this technique, morbidity and mortality, as well as functional results during follow up were evaluated. RESULTS: The indications of this technique were: previous failure of a left colon interposition (1), oesophageal disconnection due to a gastro-pleural fistula (1), total oesophagogastrectomy (1) and partial oesophagogastrectomy (1) due to the ingestion of caustic substances, respectively. Gastrointestinal complications were the most frequent. Two cervical fistulas were diagnosed which were resolved with an absolute diet, antibiotic therapy and enteral nutrition. There was no mortality. After a median follow up of 14.7 months, two patients were nourished exclusively by mouth, one by a mixed route (oral-enteral) and another exclusively by the enteral route due to an oesophageal stenosis 11 centimetres from the dental arch; this patient required dilations and is awaiting a jejunal graft. CONCLUSIONS: "Supercharged" ileocoloplasty is a complex treatment option for the total reconstruction of the oesophagus when no other alternatives are available. Postoperative morbidity is significant but the functional results are good.

Ileocoloplastia supercharged: una opción para reconstrucciones esofágicas complejas / Supercharged ileocoloplasty: an option for complex oesophageal reconstructions

Introducción La reconstrucción esofágica en un segundo tiempo es una intervención quirúrgica compleja que, en algunos casos, requiere asociar técnicas microvasculares para aumentar el flujo vascular a la plastia (supercharged). La ileocoloplastia supercharged permite crear una plastia larga que hace posible sustituir la totalidad del esófago. Describimos nuestra experiencia inicial con esta técnica para la reconstrucción de todo el esófago. Material y métodos La revisión retrospectiva del periodo octubre de 2007 a diciembre de 2009 identificó a 4 pacientes a los que se les realizó una reconstrucción esofágica diferida con una ileocoloplastia supercharged. Se evaluaron las indicaciones de esta técnica, la morbilidad y mortalidad, así como, los resultados funcionales durante el seguimiento. Resultados Las indicaciones de esta técnica fueron: fracaso previo de una interposición de colon izquierdo (1), desconexión esofágica por fístula gastropleural (1), esofagogastrectomía total (1) y esofagogastrectomía parcial (1) por ingesta de cáusticos, respectivamente. Las complicaciones digestivas fueron las más frecuentes. Se diagnosticaron dos fístulas cervicales que se resolvieron con dieta absoluta, antibioticoterapia y nutrición enteral. No hubo mortalidad. Tras una mediana de seguimiento de 14,7 meses, dos pacientes se nutrían exclusivamente por vía oral, uno por vía mixta (oral-enteral) y otro exclusivamente por vía enteral debido a una estenosis esofágica a 11 centímetros de arcada dentaria; este paciente ha precisado dilataciones y está pendiente de un injerto de yeyuno. Conclusiones La ileocoloplastia supercharged es una opción técnica compleja para reconstruir todo el esófago cuando no se dispone de otras alternativas. La morbilidad postoperatoria es significativa pero los resultados funcionales son buenos (AU)

[Laparoscopic adrenalectomy for suspected isolated adrenal metastasis]. / Adrenalectomía laparoscópica por sospecha de metástasis adrenal solitaria.

INTRODUCTION: Isolated adrenal metastasis is uncommon. Both resection and the laparoscopic approach in this entity are controversial. The aim of this study was to evaluate the indications, diagnosis and utility of laparoscopic adrenalectomy (LA) in patients with isolated adrenal metastasis. PATIENTS AND METHOD: A prospective study was conducted in patients with current or previous tumoral disease and with isolated adrenal metastasis. RESULTS: Sixteen patients, with a mean age of 58 years, were selected. Fifteen LA were performed (one patient was found to have an inoperable tumor at surgery). Histopathological analysis revealed non-tumoral disease in two patients. The most common metastatic disease was non-small cell lung carcinoma (NSCLC) (10 patients), followed by colorectal cancer metastasis (two patients). The mean tumor size was 4.7 cm and was 3.8 cm on computed tomography (p = 0.09). The disease-free interval (DFI) in the NSCLC group was shorter than that in the remaining tumors (p = 0.17). The mean length of follow-up was 39 months, with a mean survival of 39.7 months. The mean actuarial survival at 2 and 5 years was 61% and 17%. At the end of the study, five patients were alive: two were disease free, one had recurrent disease, one had margin involvement and one was awaiting resection of the primary tumor. Eight patients died. One patient survived 9 years after surgery. CONCLUSIONS: LA for metastasis can be performed without oncological disadvantage and should be offered to patients with resectable disease, a DFI > 6 months, and a tumoral size that allows laparoscopic resection.

Adrenalectomía laparoscópica por sospecha de metástasis adrenal solitaria / Laparoscopic adrenalectomy for suspected isolated adrenal metastasis

Introducción. La metástasis adrenal solitaria es una afección infrecuente y su resección resulta controvertida. Asimismo, se discute su abordaje laparoscópico. El objetivo de este estudio es evaluar las indicaciones, el diagnóstico y la utilidad de la adrenalectomía laparoscópica (AL) en pacientes con metástasis adrenal solitaria. Pacientes y método. Se realizó un estudio prospectivo en pacientes con enfermedad tumoral actual o previa y con metástasis adrenal solitaria. Resultados. Se seleccionó a 16 pacientes, con una media de edad de 58 años. Se practicaron 15 AL (un caso resultó irresecable); 2 pacientes presentaron histopatología no tumoral. La enfermedad metastásica más frecuente fue el carcinoma pulmonar de no células pequeñas (CPNCP) (10 casos), seguido de la metástasis de carcinoma colorrectal (2 casos). El tamaño tumoral medio fue de 4,7 cm, y en la tomografía computarizada fue de 3,8 cm (p = 0,09). El intervalo libre de enfermedad (ILE) en el grupo con CPNCP fue menor que para las demás tumoraciones (p = 0,17). El tiempo medio de seguimiento fue de 39 meses, con una supervivencia media de 39,7 meses. La supervivencia actuarial media a los 2 y a los 5 años fue del 61 y el 17%. Al finalizar el estudio, 5 pacientes permanecen vivos: 2 libres de enfermedad, 1 con recurrencia metastásica, 1 con márgenes afectos y 1 pendiente de resección del tumor primario. Fallecieron 8 pacientes. Un paciente sobrevivió 9 años tras la cirugía. Conclusiones. La adrenalectomía laparoscópica por metástasis puede realizarse sin ninguna desventaja oncológica y se debe ofrecerla a pacientes con enfermedad resecable, ILE > 6 meses y un tamaño tumoral resecable mediante esta técnica (AU)
