Results of a survey on peri-operative nutritional support in pancreatic and biliary surgery in Spain / Resultados de una encuesta sobre el soporte nutricional perioperatorio en la cirugía pancreática y biliar en España

INTRODUCTION: a survey on peri-operative nutritional support in pancreatic and biliary surgery among Spanish hospitals in 2007 showed that few surgical groups followed the 2006 ESPEN guidelines. Ten years later we sent a questionnaire to check the current situation. METHODS: a questionnaire with 21 items sent to 38 centers, related to fasting time before and after surgery, nutritional screening use and type, time and type of peri-operative nutritional support, and number of procedures. RESULTS: thirty-four institutions responded. The median number of pancreatic resections (head/total) was 29.5 (95% CI: 23.0-35; range, 5-68) (total, 1002); of surgeries for biliary malignancies (non-pancreatic), 9.8 (95% CI: 7.3-12.4; range, 2-30); and of main biliary resections for benign conditions, 10.4 (95% CI: 7.6-13.3; range, 2-33). Before surgery, only 41.2% of the sites used nutritional support (< 50% used any nutritional screening procedure). The mean duration of preoperative fasting for solid foods was 9.3 h (range, 6-24 h); it was 6.6 h for liquids (range, 2-12). Following pancreatic surgery, 29.4% tried to use early oral feeding, but 88.2% of the surveyed teams used some nutritional support; 26.5% of respondents used TPN in 100% of cases. Different percentages of TPN and EN were used in the other centers. In malignant biliary surgery, 22.6% used TPN always, and EN in 19.3% of cases. CONCLUSIONS: TPN is the commonest nutrition approach after pancreatic head surgery. Only 29.4% of the units used early oral feeding, and 32.3% used EN; 22.6% used TPN regularly after surgery for malignant biliary tumours. The 2006 ESPEN guideline recommendations are not regularly followed 12 years after their publication in our country

INTRODUCCIÓN: realizamos una encuesta sobre soporte nutricional perioperatorio en cirugía pancreática y biliar en hospitales españoles en 2007, que mostró que pocos grupos quirúrgicos seguían las guías de ESPEN 2006. Diez años después enviamos un cuestionario para comprobar la situación actual. MÉTODOS: treinta y ocho centros recibieron un cuestionario con 21 preguntas sobre tiempo de ayunas antes y después de la cirugía, cribado nutricional, duración y tipo de soporte nutricional perioperatorio, y número de procedimientos. RESULTADOS: respondieron 34 grupos. La mediana de pancreatectomías (cabeza/total) fue de 29,5 (IC 95 %: 23,0-35; rango, 5-68) (total, 1002), la de cirugías biliares malignas de 9,8 (IC 95 %: 7,3-12,4; rango, 2-30) y la de resecciones biliares por patología benigna de 10,4 (IC 95 %: 7,6-13,3; rango, 2-33). Solo el 41,2 % de los grupos utilizaban soporte nutricional antes de la cirugía (< 50 % habian efectuado un cribado nutricional). El tiempo medio de ayuno preoperatorio para sólidos fue de 9,3 h (rango, 6-24 h), y de 6,6 h para líquidos (rango, 2-12). Tras la pancreatectomía, el 29,4 % habían intentado administrar una dieta oral precoz, pero el 88,2 % de los grupos usaron algún tipo de soporte nutricional y el 26,5 % usaron NP en el 100 % de los casos. Los demás grupos usaron diferentes porcentajes de NP y NE en sus casos. En la cirugía biliar maligna, el 22,6 % utilizaron NP siempre y NE en el 19,3 % de los casos. CONCLUSIONES: la NP es el soporte nutricional más utilizado tras la cirugía de cabeza pancreática. Solo el 29,4 % de las unidades usan nutrición oral precoz y el 32,3 % emplean la NE tras este tipo de cirugía. El 22,6 % de las instituciones usan NP habitualmente tras la cirugía de tumores biliares malignos. Las guías ESPEN 2006 no se siguen de forma habitual en nuestro país tras más de 10 años desde su publicación

[Metástasis hepáticas sincrónicas de cáncer colorrectal. ¿Resección simultánea o diferida?] / Synchronous liver metastases from colorectal origin. Simultaneous or staged resection?

INTRODUCCIÓN: El 20-40% de las metástasis hepáticas de origen colorrectal son de tipo sincrónico. Actualmente existen tres estrategias quirúrgicas; dos de ellas proponen resecciones diferidas, y la otra, la resección simultánea. OBJETIVO: evaluar los resultados a corto y largo plazo de las resecciones simultáneas. MÉTODO: Evaluamos 212 metástasis hepáticas sincrónicas resecadas en dos centros y comparamos las intervenidas de forma simultánea con aquellas de manera diferida. Evaluamos las características demográficas, las resecciones hepáticas y las características de las metástasis. También evaluamos la morbimortalidad. RESULTADOS: Fueron resecados de manera simultánea con el tumor primario 63 pacientes, y no hubo diferencias significativas en las características demográficas. Hubo más resecciones mayores (p = 0.005) en el grupo de las diferidas. La morbimortalidad fue comparable. La insuficiencia hepática (p = 0.037) fue mayor en el grupo de las diferidas. La morbilidad fue del 33.2% en las diferidas y del 10.1% en las simultáneas (p = 0.256). La mortalidad fue del 2.83% en las diferidas y del 0.94% en las simultáneas (p = 0.508). CONCLUSIÓN: Los resultados a corto y largo plazo en ambos grupos son similares. Queda el interrogante de si la necesidad de una hepatectomía mayor favorecería la elección de un tratamiento diferido. INTRODUCTION: Between 20 and 40% of liver metastases from colorectal tumor are synchronous. Three types of surgical approaches are proposed; two of them propose a deferred resection and the other, simultaneous resection. The aim of this analysis is to assess the short- and long-term outcomes of simultaneous resections. METHOD: 212 synchronous liver metastases resected in two centers were evaluated. Comparison between those resected simultaneously with those that were in a deferred way was made. Demographics, liver resections and metastatic characteristics were evaluated. Morbidity and mortality of both alternatives are also evaluated. RESULTS: 63 patients were resected simultaneously with the primary tumor, there were no significant differences in demographic characteristics. There was a greater number of major resections (p = 0.005) in the deferred group. Morbidity and mortality was comparable in both groups. Liver failure (p = 0.037) was higher in the deferred group. Morbidity was 33.2% in the deferred and 10.1% for the simultaneous (p = 0.256). Mortality rate was 2.83% in the deferred and 0.94% in the simultaneous group (p = 0.508). CONCLUSION: Short and long-term outcomes for both groups are similar. A question remains to be answered: the need of a major hepatectomy will favor the election of a deferred treatment?

Un estudio biinstitucional]. / Short and long-term outcomes of the re-hepatectomies as part of multi-modal treatment of hepatic metastases from colo-rectal origin. Bi-institutional study.

INTRODUCCIÓN: Un alto porcentaje de pacientes que reciben una hepatectomía por metástasis de cáncer colorrectal presentarán recidiva hepática, y en algunas será posible una nueva resección. La utilidad de las hepatectomías repetidas continúa siendo discutida. OBJETIVO: Evaluar los resultados obtenidos a corto y largo plazo. MÉTODO: Fueron analizadas 68 rehepatectomías de dos instituciones. Se analizaron datos demográficos y características de la enfermedad metastásica y de las resecciones hepáticas. Los tipos de complicaciones y la morbimortalidad también fueron analizados, al igual que la supervivencia y el tiempo libre de enfermedad. Se evaluaron algunos de los factores de mal pronóstico mencionados en la literatura. RESULTADOS: El análisis de los datos de corto plazo no mostró diferencias significativas entre los pacientes de primera hepatectomía y de hepatectomías repetidas, a excepción del porcentaje de fístulas biliares posoperatorias (p = 0.001). La supervivencia a 1 año es similar, mientras que a 3 y 5 años mostró diferencias significativas (p = 0.024 y 0.004, respectivamente). Los factores de mal pronóstico referidos en la literatura no fueron representativos en esta serie. CONCLUSIÓN: Los resultados a corto plazo de los pacientes con rehepatectomía son similares a los de aquellos resecados una vez. Los resultados a largo plazo de las rehepatectomías son inferiores a otros publicados. INTRODUCTION: A high percentage of patients undergoing hepatectomy for metastatic colorectal liver disease will have a recurrence. Of these, some can be subject to a new resection. The usefulness of repeated hepatectomy remains controversial. The aim of this study is to evaluate the results of short and long-term outcomes in repeated hepatectomies. METHODS: They were re-analyzed 68 repeated hepatectomies from two institutions. Demographics, characteristics of metastatic disease and hepatic resections were analyzed. Types of complications, morbidity and mortality were also analyzed as survival and disease-free time. Some of the factors of poor prognosis mentioned in the literature were evaluated. RESULTS: The analysis of short-term data showed no statistically significant differences between patients with first and repeated hepatectomy, except the percentage of postoperative biliary leakage (p = 0.001). The 1-year survival was similar while 3 and 5 years survival showed significant differences (p = 0.024 and 0.004, respectively). The factors of poor prognosis referred in the literature were not representative in this series. CONCLUSION: The short-term results of repeated hepatectomy are similar to those resected once. Long term result are inferior to other published series.

[Liver resections as radical surgery for hepatic hydatidosis: results in 50 patients]. / Resultados de las resecciones hepáticas como tratamiento radical de la hidatidosis hepatica en 50 pacientes.

INTRODUCTION: Among several regions in the world hepatic hydatidosis can be considered endemic. Currently there are many available treatments for this disease, been surgery the most effective one. Surgical procedures can be divided in two main groups, radical and non-radical procedures. The goal of this work is to evaluate the morbidity, mortality and percentage of recurrence in patients treated with hepatectomies, comparing them with other publications. MATERIAL AND METHODS: This retrospective study was carried out in a series from Spain and Argentina. We analyzed the following data: sex, age, type of resection, associated surgical gestures, presence of liver disease, operative time, blood transfusion, morbidity, mortality, hospital stay, re-hospitalization, recurrence and follow up. Dindo--Clavien classification was used for complications, and International Hepato-Pancreato-Biliary Association (IHPBA) Brisbane classification for hepatectomies. Mortality was considered until 90 days after surgery. To evaluate the recurence we only included patients followed over 6 months. RESULTS: Indications for liver resections were performed in patients with cysts larger than 5 centimeters, multiple cysts, large cysts, with bile duct communicated or suspicion of this communication. Five patients required blood transfusions (10%) with a median for these 5 patients of 740 ml and 74 ml for the complete series. The median operative time was 186 minutes (range 45 to 1,050 minutes). Median hospital stay was 7.7 days. Monitoring more than 6 months was conducted in 38 patients. CONCLUSIONS: We believe that hepatic hydatid disease is a multifaceted disease and requires more than one therapeutic approach. Hepatectomy with complete resection of the parasite offers the possibility of doing so in a controlled and safe way by experienced hands, ensuring good results in the treatment of this disease.

Colangiocarcinoma hiliar: el número de ganglios positivos y la relación ganglios positivos/ganglios totales son un factor pronóstico importante de supervivencia / Hilar cholangiocarcinoma: The number of positive nodes and positive node/total node ratio is a significant prognostic factor for survival

INTRODUCCIÓN: El tratamiento quirúrgico del colangiocarcinoma hiliar representa un verdadero desafío. Múltiples factores pronósticos han sido propuestos. El número de ganglios positivos y la relación ganglios positivos y ganglios totales (G+/Gt) son considerados por algunos autores como los más importantes. MATERIAL Y MÉTODO: Se analiza una serie de 58 pacientes con tumores de Klatskin. Se evalúan los factores pronósticos y la supervivencia con especial interés en el impacto pronóstico del número de ganglios positivos y su relación con los ganglios totales. RESULTADOS: La resecabilidad fue de 78% con una sobrevida a 5 años del 32%. La mediana de ganglios estudiados fue de 9,5. No se encontraron diferencias significativas en varios de los factores pronósticos analizados. La presencia de 2 o más ganglios positivos o una relación G+/Gt ≥ 0,2 resultaron ser factores de mal pronóstico. CONCLUSIÓN: La relación entre ganglios positivos sobre los ganglios totales y el número de ganglios positivos son factores pronósticos importantes

INTRODUCTION: Surgical treatment of hilar cholangiocarcinoma remains a challenge. Multiple prognostic factors have been proposed. The number of positive nodes and the ratio between positive lymph node and total lymph node (G+/Gt) are considered by some authors as the most important factor. MATERIAL AND METHODS: We analyzed a series of 58 patients with Klatskin tumors. We evaluated the prognostic factors and survival with emphasis on the prognostic impact of the number of positive nodes and its relation to total lymph nodes. RESULTS: Resectability was 78% with a 5-year survival of 32%. The median number of nodes examined was 9.5. No significant differences were found in several of the proposed prognostic factors. The presence of 2 or more positive nodes or a ratio G+/Gt ≥ 0.2 were found to be poor prognostic factors. CONCLUSION: The relationship between positive lymph nodes and total lymph nodes and the number of positive lymph nodes are important prognostic factors

La estenosis del tronco celiaco y duodenopancreatectomía cefálica: ¿un riesgo infravalorado? / Celiac artery stenosis and cephalic duodenopancreatectomy: An undervalued risk?

Introducción La estenosis significativa del tronco celiaco habitualmente cursa de forma asintomática. No obstante, cuando se interrumpe la arcada de las arterias pancreatoduodenales, puede producirse isquemia visceral. El objetivo de este estudio es determinar si la estenosis preoperatoria del tronco celiaco es un factor de riesgo de complicaciones en pacientes sometidos a duodenopancreatectomía (DPC). Material y métodos Hemos analizado retrospectivamente a 58 pacientes consecutivos sometidos a DPC. Hemos relacionado la estenosis significativa del tronco celiaco con la evolución posquirúrgica. En todos los casos se ha realizado un estudio mediante tomografía computarizada multidetector (TCDM) de 16 canales en tres fases hepáticas. Hemos revisado la TCDM prequirúrgica centrándonos en la morfología del tronco celiaco, especialmente la presencia o ausencia de estenosis significativa (> 50%).Resultados Encontramos estenosis del tronco celiaco > 50% en 13 pacientes (22%). La mortalidad total fue de 3 pacientes (5%). La morbilidad total fue del 62%. En 16 pacientes (28%) hubo complicaciones graves, de los que 8 (62%) pertenecen al grupo de estenosis significativa del tronco celiaco (p=0,004); 10 pacientes (17%) presentaron fístula pancreática, 5 (38%) vs. 5 (11%) (p=0,036); 14 pacientes (24%) necesitaron reoperación, 7 (54%) vs. 7 (16%) (p=0,009); 7 pacientes (12%) presentaron hemoperitoneo, 4 (31%) vs. 3 (7%) (p=0,038), en los grupos con y sin estenosis del tronco celiaco respectivamente. Conclusiones La estenosis radiológicamente significativa del tronco celiaco es un factor de riesgo de complicaciones graves tras DPC. El estudio del calibre de la AMS con TCDM debería ser sistemático antes de una DPC. Debería valorarse preoperatoriamente la corrección de la estenosis significativa del tronco celiaco (AU)

Introduction Significant celiac trunk or artery stenosis (CAS) is normally asymptomatic. However, when the arteries of the pancreatoduodenal arcade are occluded, it could trigger avisceral ischaemia. The objective of this study is to determine whether preoperative CAS is a risk factor for developing complications in patients subjected to duodenopancreatectomy(DPC). Material and methods: We have retrospectively analysed 58 consecutive patients subjected to DPC. We have associated significant CAS with post-surgical outcome. In all cases a 16-channel multidetector computed tomography (MDCT) in three hepatic phases was performed. We have reviewed the pre-surgical MDCT focusing on the morphology of the celiacartery (CA), particularly in the presence or absence of significant stenosis (>50%). Results: We found CAS >50% in 13 patients (22%). The overall mortality was 5% (3 patients). Serious complications developed in 16 (28%) patients, 8 (62%) of whom belonged to the group with significant CAS (P = .004). Ten patients (17%) had a pancreatic fistula, 5 (38%) vs. 5 (11%)(P = .036); Fourteen patients (24%) needed new surgery, 7 (54%) vs. 7 (16%) (P = .009); Seven patients (12%) had a haemoperitoneum, 4 (31%) vs. 3 (7%) (P = .038), in the group with and without CAS, respectively. Conclusions: Significant radiological CAS is a risk factor of serious complications after DPC. The study of the calibre of the superior mesenteric artery (SMA) with MDCT should beroutine before a DPC. The correction of a significant CAS should be evaluated preoperatively (AU)

CONCLUSIONS: Significant radiological CAS is a risk factor of serious complications after DPC. The study of the calibre of the superior mesenteric artery (SMA) with MDCT should be routine before a DPC. The correction of a significant CAS should be evaluated preoperatively.

Extra-Glissonian approach in liver resection.

BACKGROUND: In this study we analyzed our most recent experience in the use of the extraglissonian approach to the hilar structures in two circumstances: pedicle transection during major liver resections, and selective clamping in minor hepatectomies. METHODS: The major liver resections study group consisted of 89 cases. Extraglissonian approach and stapler transection of hilar structures was used in 61 (69%). The study group of minor liver resections consisted of 103 cases. Extraglissonian approach and selective clamping was used in 27 cases (26%). RESULTS: In major hepatectomies pedicle stapling and hilar dissection demonstrated a similar operative time (240 vs. 260 min; P = 0.230); no differences were observed in the amount of haemorrhage (800 ml vs. 730 ml; P = 0.699), number of patients transfused (16 vs. 6; P = 0.418) and volume of blood transfused (4 PRC vs. 4 PRC; P = 0.521). Duration of vascular pedicle occlusion was 35 vs. 30 min respectively (P = 0.293). Major complications (grade >or=3a) occurred in 18 (20%) patients and mortality rates (4.9% vs. 3.5%; P = 0.882) were similar for both group. In minor liver resections there were no differences between Pringle and selective clamping in operative time (240 vs. 240 min; P = 0.321), haemorrhage (435 ml vs. 310 ml; P = 0.575), number of patients transfused (18 vs. 7; P = 0.505) and volume blood transfused (4 PRC vs. 3 PRC; P = 0.423). Major complications (grade >or=3a) occurred in 14 (14%) patients, and mortality (2.6% vs. 3.7%; P = 0.719) were similar for both groups. However, the duration of pedicle clamping was significantly longer in the selective clamping group (26 +/- 21 minutes vs. 44 +/- 18 minutes) (P = 0.001). CONCLUSIONS: The extraglissonian approach can be extremely useful in liver surgery. Selective clamping with extraglissonian approach avoids ischemia to the other hemiliver. Selective clamping it is also important from the homodynamic point of view because there is no splanchnic stasis and low fluid replacement.

[Results of hepatobiliary and pancreatic surgery according to DRG in a level 2 hospital surgery department during the years 2005-2006]. / Resultados de la cirugía hepatobiliopancreática en un servicio de cirugía de un hospital de segundo nivel según los GRD durante el bienio 2005-2006.

OBJECTIVE: To assess the results of the hepatobiliary and pancreatic surgery of a surgery department during 2005-2006 using the diagnostic related groups. MATERIALS AND METHOD: The data were obtained from the CMBD-HA of the Catalan Health Service. We assessed the frequency, hospital stay and mortality of the surgical procedures. The results were compared with the 63 public hospitals, and the 8 of them belonging to the Catalan Health Institute. RESULTS: In our area, a clear trend is observed in referrals for certain types of complex procedures on the liver, pancreas and biliary system excluding cholecystectomy with or without associated morbidities (7-11%) without exceeding the population percentage (12%). In our centre, the impact on hospital stay is more evident in complex procedures. The total savings in our centre during the years 2005-2006 compared with the XHUP hospitals group were 2212 days of hospital stay with an equivalent cost saving of more than one million euro. The frequency and the results of hospital stay and mortality of laparoscopic and open cholecystectomy were those expected for the population covered by a general hospital. The mortality in complex procedures was half of that of the whole public network or the ICS centres. CONCLUSIONS: In the complex hepatobiliary-pancreatic pathology, the mortality, and cost savings in our centre appear to be the result of, not only the high volume of procedures, but also to specialisation and factors related to the structure of the department, and surgeon training.

Objetivo. Evaluar los resultados de la cirugía hepatobiliopancreática de un servicio de cirugía durante el bienio 2005-2006, mediante los grupos relacionados por el diagnóstico. Materiales y método. Los datos se han obtenido del Registro del Conjunto Mínimo Básico de Datos de los Hospitales de Agudos del CatSalut. Se ha valorado la frecuencia, la estancia y la mortalidad. Los resultados han sido comparados con los 63 hospitales públicos de Cataluña (XHUP) y con los 8 de ellos que pertenecen al Instituto Catalán de la Salud (ICS). Resultados. Se observa, en nuestra área de influencia, una clara tendencia a la referencia para cierto tipo de procedimientos complejos (7-11%), sin superarla proporción poblacional (12%). En nuestro centro, el impacto en las estancias hospitalarias es más evidente en los procedimientos complejos. El ahorro total de recursos de nuestro servicio en el bienio2005-2006 en relación con el grupo de hospitales de la XHUP fue de 2.212 días de estancia hospitalaria, cuyo coste equivale a más de un millón de euros. La frecuencia y los resultados sobre las estancias hospitalarias y la mortalidad de la colecistectomía son los esperados para la población que se atiende como hospital general. La mortalidad en los procedimientos complejos fue la mitad que la observada para el conjunto de hospitales de la XHUP o del ICS. Conclusiones. En la patología hepatobiliopancreática compleja, creemos que la mortalidad y el ahorro de recursos en nuestro centro se deben no sólo al volumen, sino a la especialización y los factores relacionados con la estructura del servicio y el entrenamiento de los cirujanos (AU)

Descripción de la técnica y evaluación de nuestra experiencia inicial / Cephalic duodenopancreatectomy in periampullary tumours. Dissection of the superior mesenteric artery as aninitial approach. Description of the technique and an assessment of our initial experience

Introducción. La duodenopancreatectomía cefálica (DPC) con abordaje inicial de la arteria mesentérica superior (AMS) ha sido descrita como una técnica útil para reducir las pérdidas de sangre y evitar una intervención inútil si hay afectación arterial. Objetivos. Analizar los resultados de dos modificaciones recientes en la técnica quirúrgica de la DPC introducidas en nuestro grupo: disección primaria de la AMS y la gastroenterostomía antecólica. Pacientes y método. Se dividió a los pacientes en 2 grupos, según hayan recibido o no disección inicial de la AMS. También se analizaron los resultados según el tipo de reconstrucción gástrica. Se comparan los resultados perioperatorios y a largo plazo. Resultados. La mortalidad general fue del 5% sin diferencias entre la DPC con abordaje inicial de la AMS y la técnica convencional. La tasa de transfusión (p < 0,001), el volumen transfundido (p = 0,001) y la incidencia general de complicaciones fue menor (p = 0,01) en el grupo con disección de la AMS. La estancia postoperatoria también fue significativamente menor (p # 0,001). A pesar de que la afectación ganglionar fue más frecuente en los pacientes operados con abordaje inicial de la AMS (p = 0,001), la tasa de recidiva fue la misma que con la técnica convencional. Dentro del grupo con disección inicial de la AMS, aquellos con reconstrucción antecólica presentaron con menor frecuencia retraso en el vaciamiento gástrico (p = 0,008). Conclusiones. La DPC con abordaje inicial de la AMS es una técnica segura. La transfusión, las complicaciones y la estancia hospitalaria son mejores. Cuando se asocia a reconstrucción duodenoyeyunal antecólica, los retrasos de vaciamiento gástrico son menos frecuentes (AU)

Introduction. Pancreatoduodenectomy (PD) with initial dissection of the superior mesenteric artery (SMA) has been described as a useful technical variant to reduce blood loss and to avoid an unnecessary intervention in those cases with arterial involvement. Objectives. To analyse the results of two recent technical modifications of PD introduced by our group: initial dissection of SMA and antecolic gastroenterostomy. Patients and method. Patients were divided into two groups: with and without initial dissection of the SMA. The results were also analysed according to the type of gastric reconstruction. Perioperative and long-term results are compared. Results. The overall mortality was 5%, with no significant differences between the initial SMA dissection and conventional PD. The transfusion rate (p < 0.001), the volume of blood products transfused (p = 0.001), and the overall complication rate were lower (p = 0.01) in the initial SMA dissection group. Also the postoperative hospital stay was significantly lower (p # 0.001). Despite a higher frequency of lymph node involvement in patients treated with initial SMA dissection (p = 0.001), the recurrence rate was similar between both groups. Among patients with initial SMA dissection, those who received antecolic reconstruction had a lower rate of delayed gastric emptying (p = 0.008). Conclusions. Initial SMA dissection PD is a safe technique. The transfusion rate, morbidity and postoperative hospital stay are better when compared with conventional CPD. When an antecolic duodenal-jejunal reconstruction is associated, delayed gastric emptying cases are less frequent (AU)

[Role of intra-operative echography and computed tomography with multiple detectors in the surgery of hepatic metastases: a prospective study]. / Papel de la ecografía intraoperatoria y la tomografía computarizada con multidetectores en la cirugía de las metástasis hepáticas: estudio prospectivo.

OBJECTIVES: To study the performance of the intraoperative ecography in the diagnosis of new liver metastases in the era of computerized tomography (CT) with multidetectors and its impact on the surgical operation. PATIENTS AND METHOD: Between February 2005 and April 2006 patients with resectable liver metastases where studied prospectively in a multidisciplinary meeting (surgeons, radiologist, oncologist). The preoperative CT findings were compared with the intraoperative findings and ultrasound study and the results of the surgical operation. RESULTS: Forty-five candidates for curative surgery had a total of 171 hepatic lesions. CT correctly detected 115 lesions with a sensitivity of 67%, and a positive predictive value of 97%, with a false negative rate of 33% and false positive rate of 2%. In 5 patients intraoperative findings were the cause of changing the surgical procedure, three patients were unresectable (rate of resectability of 93%) and two patients needed a larger hepatic resection. CONCLUSIONS: CT with multidetectors and multidisciplinary meetings are the most important factors in the decision making of surgery of liver metastases with a high resectability rate. Intraoperative ecography is useful for the detection of 10% more liver metastases, but rarely involves a change in the surgical procedure.

Objetivos. Estudiar el papel de la ecografía intraoperatoria en el diagnóstico de nuevas metástasis hepáticas en la era de la tomografía computarizada (TC) con multidetectores y su impacto en el acto quirúrgico. Pacientes y método. Entre febrero de 2005 y abril de 2006 se estudió de forma prospectiva, en sesiones multidisciplinarias (cirujanos, radiólogos y oncólogos), a los pacientes con metástasis hepáticas resecables de cáncer colorrectal. Los hallazgos preoperatorios de la TC se compararon con los de la ecografía intraoperatoria, su correlación histológica y el resultado final de la intervención quirúrgica. Resultados. Se estudió a 45 pacientes candidatos a cirugía curativa, con un total de 171 metástasis hepáticas. La TC detectó correctamente 115 lesiones con una sensibilidad del 67%, un valor predictivo positivo del 97%, una tasa de falsos negativos del 33% y una tasa de falsos positivos del 2%. En 5 ocasiones los hallazgos intraoperatorios condicionaron un cambio en el acto quirúrgico programado: en 3 pacientes eran irresecables (tasa de resecabilidad del 93%) y 2 pacientes precisaron de resecciones más amplias de las previamente programadas. Conclusiones. La TC con multidetectores como prueba de imagen preoperatoria y las sesiones multidisciplinarias son el factor más importante en la toma de decisiones en la cirugía de las metástasis hepáticas y nos permiten obtener una alta tasa de resecabilidad. La ecografía intraoperatoria hepática nos permite encontrar un mayor número de metástasis y realizar una correcta delimitación anatómica y, en ocasiones, condiciona un cambio en el acto quirúrgico programado (AU)
