RESUMO

OBJETIVOS: La cirugía laparoscópica multipuerto (CLM) ha demostrado su seguridad y efectividad en la cirugía del colon. Con la intención de reducir la agresividad surgen otras técnicas como la cirugía por puerto único (SILS). El objetivo de este metaanálisis es evaluar la seguridad y la viabilidad de la técnica SILS en la cirugía del colon. MATERIAL Y MÉTODOS: Se realiza un metaanálisis de 27 estudios observacionales y uno prospectivo aleatorizado mediante el modelo de efectos aleatorios. RESULTADOS: Se han analizado 2.870 procedimientos: 1.119 SILS y 1.751 CLM. No se han encontrado diferencias estadísticamente significativas en la edad (DMP 0,28 [−1,13, 1,68]; p = 0,70), IMC (DMP −0,63 [−1,34, 0,08]), ASA (DMP −0,02 [−0,08, 0,04]; p = 0,51), longitud de incisión (DMP −1,90 [−3,95, 0,14]; p = 0,07), tiempo operatorio (DMP −2,69 [−18,33, 12,95]; p = 0,74), complicaciones (OR = 0,89 [0,69, 1,15]]; p = 0,37), conversión a laparotomía (OR = 0,59 [0,33, 1,04]; p = 0,07), mortalidad (OR = 0,91 [0,36, 2,34]; p = 0,85) o número de ganglios obtenidos (DMP 0,13 [−2,52, 2,78]; p = 0,92). La pérdida de sangre (DMP −42,68 [−76,79, −8,57]; p = 0,01) y la estancia hospitalaria (DMP −0,73 [−1,18, −0,28]; p = 0,001) son significativamente menores en el grupo SILS. CONCLUSIONES: La cirugía colorrectal mediante SILS es segura y efectiva, con ligeros beneficios respecto a la CLM. Sin embargo, se necesitan más estudios aleatorizados antes de que la SILS se pueda considerar una alternativa a la CLM


OBJECTIVE: Multiport laparoscopic surgery in colon pathology has been demonstrated as a safe and effective technique. Interest in reducing aggressiveness has led to other procedures being described, such as SILS. The aim of this meta-analysis is to evaluate feasibility and security of SILS technique in colonic surgery. MATERIAL AND METHODS: A meta-analysis of twenty 7 observational studies and one prospective randomized trial has been conducted by the use of random-effects models. RESULTS: A total amount of 2870 procedures was analyzed: 1119 SILS and 1751 MLC. We did not find statistically significant differences between SILS and MLC in age (WMD 0.28 [−1.13, 1.68]; P=.70), BMI (WMD −0.63 [−1.34, 0.08]; P=.08), ASA score (WMD −0.02 [−0.08, 0.04]; P=.51), length of incision (WMD −1.90 [−3.95, 0.14]; P=.07), operating time (WMD −2.69 (−18.33, 12.95]; P=.74), complications (OR = 0.89 [0.69, 1.15]; P=.37), conversion to laparotomy (OR = 0.59 [0.33, 1.04]; P=.07), mortality (OR = 0.91 [0.36, 2.34]; P=.85) or number of lymph nodes harvested (WMD 0.13 [−2.52, 2.78]; P=.92). The blood loss was significantly lower in the SILS group (WMD −42.68 [−76.79, −8.57]; P=.01) and the length of hospital stay was also significantly lower in the SILS group (WMD −0.73 [−1.18, −0.28]; P=.001). CONCLUSION: Single-port laparoscopic colectomy is a safe and effective technique with additional subtle benefits compared to multiport laparoscopic colectomy. However, further prospective randomized studies are needed before single-port colectomy can be considered an alternative to multiport laparoscopic surgery of the colon

RESUMO

Introducción La apendicitis es el proceso abdominal de urgencia más común. El tratamiento es quirúrgico y la cirugía laparoscópica mediante una única incisión (CLIU) implica la realización de la cirugía laparoscópica a través de un único punto transumbilical, en un intento de superar los resultados de la cirugía laparoscópica. Material y método Entre junio de 2009 y agosto de 2010, 73 pacientes con sospecha de apendicitis aguda fueron operados por la técnica CLIU. Todos los pacientes fueron intervenidos por el mismo equipo quirúrgico y el ombligo fue el único punto de entrada. El dolor postoperatorio se evaluó en el momento del alta de acuerdo a una escala numérica. Resultados Ninguno de los pacientes requirió conversión a laparoscopia convencional. El tiempo quirúrgico medio fue de 40±14 (16-80) min. No hubo complicaciones intraoperatorias ni postoperatorias. La media de dolor postoperatorio fue de 3±1 (1-7) y la estancia media hospitalaria fue de 18±7 (9-42) horas. Conclusión La CLIU es una técnica segura y eficaz para la apendicitis. En el futuro los procedimientos más comunes se podrán realizar a través del ombligo, siendo necesaria una alta experiencia en cirugía laparoscópica avanzada para introducir esta nueva técnica con seguridad sin añadir morbimortalidad (AU)

Results None of the patients required conversion to conventional laparoscopy. The mean surgical time was 40±14 (16-80) minutes. There were no complications during or after the surgery. The mean post-surgical pain score was 3±1 (1-7) and the mean hospital stay was 18±7 (9-42) hours. Conclusion SILS is a safe and effective technique for appendicitis.

RESUMO

BACKGROUND: The increased incidence of morbid obesity has resulted in an increase in bariatric surgery. The gastrojejunostomy performed during Roux-en-Y gastric bypass (RYGBP) operations has technical variability with different outcomes and complication-rates immediate postoperatively and at long-term follow-up. METHODS: Between Jan 2000 and Feb 2005, 350 laparoscopic RYGBP procedures were performed. We present our immediate and follow-up rate of complications with total intraabdominal gastrojejunostomy, performed with the circular stapler. RESULTS: Complications of gastrojejunostomy were detected in 24 patients (6.8%): 3 anastomotic leaks (0.8%); 6 bleeding (1.7%) immediately postoperatively, and 4 stenoses (1.1%), 10 ulcers (2.8%) and 1 stenosis plus ulcer (0.3%) during long-term follow-up. There was no mortality related to the gastrojejunostomy. CONCLUSIONS: The gastrojejunostomy with circular stapler is an easily reproducible procedure. The rate of complications has been low. Surgeons who perform laparoscopic RYGBP should have a careful learning curve, and should be aware of the potential complications and their management.

RESUMO

Introducción. La morbimortalidad de las resecciones hepáticas (RH) ha descendido en las últimas décadas y presenta tasas de mortalidad < 5% y de morbilidad < 30%. Nuestro objetivo es presentar una serie de 200 RH sin mortalidad y analizar los factores que pudiesen haber intervenido en la aparición de complicaciones. Pacientes y método. Entre enero de 1996 y octubre de 2003 se realizaron 200 RH en 177 pacientes. Las indicaciones más frecuentes fueron las metástasis hepáticas en 123 casos (61,5%), los tumores hepáticos malignos primarios en 27 casos (13,5%), los tumores de las vías biliares en 27 casos (13,5%) y una enfermedad benigna en 23 casos (11,5%). El 51% de las resecciones hepáticas se realizó bajo control vascular hemihepático y en el 49% se llevó a cabo resecciones de segmentos centrales, así como resecciones segmentarias y atípicas. Relacionamos la morbilidad con la edad, el sexo, la comorbilidad previa, el estado del hígado, la indicación quirúrgica, el número de resecciones, la resección mayor o menor, la resección extendida a otros órganos, el tipo de oclusión vascular, las necesidades transfusionales, el tiempo quirúrgico, la estancia hospitalaria y la experiencia del equipo quirúrgico. Resultados. No hubo mortalidad postoperatoria. La morbilidad fue del 17,5% (35 pacientes) y fueron más frecuentes las complicaciones biliares (8%). La morbilidad fue superior en los pacientes transfundidos (p < 0,001). La transfusión fue superior en las resecciones mayores, en las primeras 100 resecciones y en las que precisaron un tiempo quirúrgico prolongado. En las resecciones segmentarias, la maniobra de Pringle supuso un descenso de las tasas de transfusión, aunque las diferencias no fueron estadísticamente significativas. En las segundas 100 resecciones hubo un descenso de la morbilidad, sin diferencias significativas. Conclusión. Las RH se pueden realizar con una morbimortalidad baja. Es importante prevenir las complicaciones biliares y se debe evitar, en lo posible, la transfusión sanguínea (AU)


Introduction. Liver resection (LR) morbidity and mortality rates have dropped in recent decades. Mortality is now below 5% and morbidity is less than 30%. Our objective was to present a series of 200 LRs without mortality and to analyze the factors that may be related to complications. Patients and method. Between January 1996 and October 2003, 200 LRs were performed in 177 patients. The most common indication was liver metastases in 123 patients (61.5%), primary malignant liver tumors in 27 patients (13.5%), bile duct tumors in 27 patients (13.5%) and benign disease in 23 patients (11.5%). Fifty-one percent of the resections were performed under hemihepatic vascular control and 49% were resections of central segments, segmentary and atypical resections. We studied the association between morbidity and age, sex, previous comorbidity, liver status, indication for surgery, number of resections, major and minor resections, resection extended to other organs, type of vascular occlusion, transfusion requirements, operating time, length of hospital stay and experience of the surgical team. Results. There was no postoperative mortality. The morbidity rate was 17.5% (35 patients) and the most common complications were biliary (8%). Morbidity was related to transfusion (transfused patients presented more complications) (P < .001). Transfusion was greater in major resections, the first 100 resections and prolonged operations. Among the segmentary resections the Pringle maneuver reduced transfusion requirements but this difference was not statistically significant. Morbidity decreased in the second 100 resections, without significant differences. Conclusion. LRs can be performed with low mortality and morbidity. Biliary complications and blood transfusion should be avoided whenever possible (AU)

RESUMO

Introducción. Clásicamente, las metástasis pulmonares se consideraban una diseminación sistémica del tumor que no precisaban cirugía. Sin embargo, hay estudios que muestran los beneficios de la metastasectomía en casos seleccionados. El objetivo es analizar la morbimortalidad de la metastasectomía pulmonar y determinar los factores de recidiva precoz. Pacientes y método. De los 42 pacientes intervenidos por metástasis pulmonares se excluyó a 4 por considerarlas irresecables intraoperatoriamente; se analizó a los 38 restantes. Las variables analizadas fueron la edad, el sexo, el tumor primario, el tiempo libre de enfermedad, las metástasis extrapulmonares resecadas, el número de metástasis, la bilateralidad, la morbimortalidad, las recidivas, las reintervenciones, el tiempo libre de enfermedad y la supervivencia. Resultados. El abordaje quirúrgico fue una toracotomía posterolateral extraserrática, y no se presentó mortalidad perioperatoria. La morbilidad fue del 11 por ciento (n = 4), y fue precisa una reintervención por un hemotórax posquirúrgico. La supervivencia a 1, 2 y 3 años fue del 87, el 61 y el 25 por ciento, respectivamente, y el índice de pacientes libres de enfermedad, del 71, el 56 y el 17 por ciento, respectivamente. Los principales factores de recidiva precoz fueron el tipo histológico del tumor (más recidivas en los sarcomas y menos en los adenocarcinomas), el tiempo libre de enfermedad entre el tumor primario y la metástasis pulmonar, y el número de metástasis. Cinco de las recidivas pulmonares fueron resecadas una segunda vez, y se pudo extirpar sólo 4 de ellos, 3 de los cuales están libres de enfermedad a los 6, 12 y 24 meses, y el cuarto presenta recidiva pulmonar a los 18 meses. Conclusiones. Las metástasis pulmonares pueden resecarse con baja morbimortalidad, y los principales factores pronósticos de supervivencia son la cirugía completa, el tipo histológico, el tiempo libre de enfermedad entre el tumor primario y la metástasis, y el número de metástasis pulmonares (AU)

RESUMO

Portal thrombosis is no longer considered a contraindication for transplantation because of the technical experience acquired in the field of liver transplantation and the development of various surgical techniques. All the same, the results obtained in portal thrombosis patients are at times suboptimal, and the surgical technique used (thromboendovenectomy or veno-venous bypass) is also controversial. Between May 1988 and December 2001, 455 liver transplants were performed, of which 32 (7%) presented portal vein thrombosis. Of these, eight belonged to the first 227 transplants (group I), and 24 to the other 228 (group II). Of the 32 cases with portal thrombosis, 20 (62%) were type Ib, seven (22%) type II/III and five (16%) type IV. Twenty-two were males (69%), with a mean age of 50 yr (range: 30-70 yr); the thrombosis in all cases developed over a cirrhotic liver: 15 cases of an ethanolic origin, 11 because of hepatitis C virus, two cases of autoimmune aetiology, one case of primary biliary cirrhosis, one case because of hepatitis B virus and two cases of a cryptogenic origin. Five cases had a history of surgical treatment for portal hypertension. The surgical method in all cases consisted of an eversion thromboendovenectomy (ETEV) under direct visual guidance, with occlusion of the portal flow using a Fogarty balloon. Once re-canalization was achieved, we performed local heparinization and end-to-end portal anastomosis. In no case was systemic post-operative heparinization performed. In the 32 cases in which thrombectomy was attempted it was achieved in 31 of them (96%), failing only in a case of type IV thrombosis, which was resolved by portal arterialization. Of the 31 successful cases, only one with type IV thrombosis re-thrombosed. The 5-yr survival rate of the patients in the series was 69%, with 10 patients dying, of whom only two from causes related to the thrombosis and the thrombosis treatment, both with type IV thrombosis. The ideal treatment for portal thrombosis during liver transplantation is controversial and depends on its extension and the experience of the surgeon. In our experience, ETEV resolves most thromboses (types I, II and III), but management of type IV, which occasionally can be treated with this technique, may require more complex procedures such as bypass, portal arterialization or cavoportal haemitransposition.

RESUMO

Introducción. Gracias a la experiencia técnica obtenida en el campo del trasplante hepático, la trombosis portal no se considera en la actualidad una contraindicación para el trasplante. Sin embargo, los resultados obtenidos en este grupo de enfermos son en ocasiones subóptimos y, además, la técnica quirúrgica a emplear es controvertida. Pacientes y método. Entre mayo de 1988 y diciembre de 2001 se han realizado 455 trasplantes hepáticos, de los que 32 (7 por ciento) presentaban trombosis de la vena porta. De éstos, ocho pertenecían a los 227 primeros trasplantes (grupo I) y 24 a los restantes 228 (grupo II). De los 32 casos con trombosis portal, 20 (62 por ciento) eran de tipo Ib, 7 (22 por ciento) de tipo II/III y 5 (16 por ciento) de tipo IV. Un total de 22 pacientes eran varones (69 por ciento), con una edad media de 50 años (rango, 30-70 años).En 5 casos existían antecedentes de tratamiento quirúrgico de la hipertensión portal. El método quirúrgico consistió, en todos los casos, en una tromboendovenectomía de eversión bajo visión directa con oclusión del flujo portal con balón de Fogarty. Una vez lograda la recanalización se procedió a la heparinización local y anastomosis portal término-terminal. No se efectuó en ningún caso heparinización postoperatoria sistémica. Resultados. De los 32 casos en que se intentó la trombectomía, ésta se logró en 31 ocasiones (96 por ciento), fracasando sólo en un caso de trombosis tipo IV que se resolvió mediante arterialización portal. De los 31 casos realizados con éxito, sólo se observó retrombosis en uno con trombosis de tipo IV. La supervivencia de los enfermos de la serie a los 5 años fue del 69 por ciento. Sólo 2 pacientes fallecieron por causas relacionadas con la trombosis y su tratamiento, ambos con trombosis de tipo IV. Conclusión. El tratamiento idóneo de la trombosis portal durante el trasplante hepático es discutido y depende su extensión y de la experiencia del cirujano. Según nuestra experiencia, la tromboendovenectomía de eversión resuelve la mayoría de la trombosis (tipos I, II y III), pero el manejo de las de tipo IV, ocasionalmente tratables con esta técnica, puede requerir el empleo de técnicas más complejas, como el bypass, la arterialización portal o la hemitransposición cavo-portal (AU)
