Necesidad de vaciamiento axilar en el cáncer de mama. Rigor en los métodos predictivos / Need for axillary lymph node dissection in breast cancer. Rigour in predictive methods

Introduccción: El objetivo es describir la validez diagnóstica y la seguridad de los métodos empleados en nuestro entorno para obviar el vaciamiento axilar en el tratamiento quirúrgico primario de mama en estadio inicial tras determinación de macrometástasis en el ganglio centinela. Métodos: Estudio observacional retrospectivo multicéntrico aprobado por el Comité de Ética. Determinación de sensibilidad, especificidad, valor predictivo positivo y negativo de los métodos: OSNA (punto de corte a 15.000 copias de ARN), score Tenon 5 (punto de corte en 5), perfil de alto riesgo (si no cumple T1G2RH+ HER-), criterios ACOSOG Z-11 y resultado de ganglio secundario. Se incluyó a pacientes con cáncer de mama dirigidas a tratamiento quirúrgico primario; tamaño T1-T2 y axila clínica y radiológicamente negativa; con resultado de ganglio centinela positivo para macrometástasis. Resultados: Se incluyó a 279 pacientes con macrometástasis en el ganglio centinela, de los cuales resultaron 69 (24,4%) linfadenectomías positivas. Los resultados de sensibilidad, especificidad, valor predictivo positivo y negativo fueron: OSNA (100%, 17%, 32%, 100%); Tenon 5 (91%, 34%, 31%, 92%); alto riesgo (82%, 32%, 28%, 85%), ACOSOG Z-11 (30%, 97%, 75%, 84%); ganglio secundario (86%, 76%, 55%, 94%). Conclusiones: El método más seguro, score Tenon 5, solo evitaría un tercio de linfadenectomías negativas. Un perfil de riesgo no ofrecería suficiente seguridad. La propuesta del grupo ACOSOG Z-11 sería el método menos seguro. La cuantificación de la macrometástasis por método OSNA no conseguiría validez diagnóstica. El análisis del ganglio secundario, siendo el método menos aplicado, sería el más válido, con mejor sensibilidad y especificidad conjunta. En nuestra valoración, ninguno de los métodos estudiados resultaría suficientemente riguroso pues no obtendrían resultados óptimos para permitir obviar la linfadenectomía

Introduction: The aim of this study was to describe the diagnostic validity and safety of the most commonly used methods to avoid axillary lymph node dissection (ALND) in the primary surgical treatment of initial-stage breast cancer after determination of sentinel node macrometastases. Methods: This multicenter, retrospective observational study was approved by the ethics committee and assessed the sensitivity, specificity, positive and negative predictive value of the following methods: OSNA (cut-off point of 15,000 RNA copies), Tenon 5 score (cut-off point 5), HIGH risk profile (RH+ HER-), ACOSOG Z-11 criteria and second-tier sentinel node outcome. We included patients with breast cancer undergoing primary surgical treatment, with T1-T2 tumours, clinically and radiologically negative axillae, and sentinel node macrometastases. Results: We included 279 patients, of whom 69 (24.4%) had a positive ALND. The results of sensitivity, specificity, positive predictive value and negative predictive value were as follows: OSNA (100%, 17%, 32%, 100%); Tenon 5 (91%, 34%, 31%, 92%); HIGH (82%, 32%, 28%, 85%), ACOSOG Z-11 (30%, 97%, 75%, 84%); SECOND (86%, 76%, 59%, 94%). Conclusions: The most accurate method, the Tenon score, would only avoid one-third of negative lymphadenectomies. Relying on a risk profile would not provide enough safety. The proposal of the ACOSOG Z-11 group was the least safe method. Quantification of macrometastases by OSNA would not be a valid diagnostic method. Second-tier sentinel node analysis, the least applied method, seems the most accurate, with the best sensitivity and specificity.In our analysis, none of the methods would be sufficiently rigorous to safely allow avoidance of ALND

Effect of bag extraction to prevent wound infection on umbilical port site wound on elective laparoscopic cholecystectomy: a prospective randomised clinical trial.

BACKGROUND: Laparoscopic cholecystectomy is the gold standard treatment for gallbladder stones. Complications due to laparoscopic procedure are rare, but rate of wound infection in some studies is about 8 %. From January 2007 to December 2008, 320 laparoscopic cholecystectomies were performed at our hospital, and in 4.7 % of them, wound infection of the umbilical trocar was identified. We believe that this infection rate could be lower and that it is necessary to implement a new technique to reduce the wound infection. The aim of the study was to evaluate the benefits of bag extraction of gallbladder to prevent the wound infection. METHODS: Two-arm, parallel, 1:1, randomised controlled trial (ISRCTN38095251). All patients suffering from symptomatic gallbladder stones of low risk were enrolled for this study and were divided into two groups in basics gallbladder extraction: with (80 patients) or, as usually, without bag (76 patients). All patients with cholecystitis or accidental gallbladder perforation were excluded. We compared all the results to establish whether meaningful differences were found. RESULTS: The final sample analysed (156 patients) consisted of 121 women and 35 men; there were 80 in the control group and 76 in the study group. There were 15 (9.6 %) diagnosed wound infections, eight cases in the study group and seven in the control group. There were no statistically significant differences. CONCLUSIONS: The determinant of wound infection in elective laparoscopic cholecystectomy is not the direct contact of the gallbladder with the wound; therefore, bag extraction is not necessary.

Risk factors for umbilical trocar site incisional hernia in laparoscopic cholecystectomy: a prospective 3-year follow-up study.

BACKGROUND: Trocar site incisional hernia (TSIH) is a common complication after laparoscopic cholecystectomy. The aim of this study was to evaluate the prevalence of TSIH and analyze the influence of several risk factors for this complication in a prospective series. METHODS: From 2007 to 2008, a prospective observational study with 3 years of follow-up was performed including all consecutive patients with cholelithiasis who underwent elective laparoscopic cholecystectomy. A multivariate analysis was performed to identify risk factors for TSIH. RESULTS: Overall, 241 patients were included. During a median follow-up period of 46.8 months, 57 patients (25.9%) were diagnosed with umbilical TSIH by physical exam or ultrasound. The multivariate analysis revealed that incision enlargement (odds ratio [OR], 14.17; 95% confidence interval [CI], 3.61 to 55.51; P < .001), wound infection (OR, 5.62; 95% CI, 2.35 to 13.42; P < .001), diabetes mellitus (OR, 2.79; 95% CI, 1.05 to 7.37; P = .0038), and obesity (OR, 2.71; 95% CI, 1.28 to 5.75; P = .009) contributed to the risk for developing a TSIH. CONCLUSIONS: Umbilical TSIH is highly prevalent. This study identified several factors that could be useful to introduce preventive measures in high-risk patients.

Variación en las reclamaciones dirigidas a un Servicio de Cirugía General y del Aparato Digestivo tras un cambio estructural y funcional hospitalario / Changes in the complaints made to a General and Gastrointestinal Surgery Department after a change in hospital structure and function

Objetivo Las reclamaciones de un servicio médico son una medida de la calidad asistencial percibida por los pacientes. El objetivo del estudio fue analizar la variación producida en el porcentaje de reclamaciones dirigidas al Servicio de Cirugía General y del Aparato Digestivo (CGD) en relación a los cambios producidos por el traslado a un nuevo hospital. Material y métodos Estudio longitudinal del porcentaje de reclamaciones dirigidas al Servicio de CGD en dos periodos de 6 meses de un mismo año (periodos A y B). Entre uno y otro periodo se realizó el traslado a un nuevo hospital. Se compara el porcentaje de reclamaciones asociadas a la actividad hospitalaria y en consultas externas. Resultados El porcentaje de reclamaciones dirigidas al Servicio de CGD fue del 3,02% dirigidas a las altas de hospitalización y 0,44% dirigidas a la atención en consultas externas. Cuando se compararon ambos periodos, se observó una disminución estadísticamente significativa de las reclamaciones en hospitalización (A: 3,74% vs B: 2,20%, p=0,006) y en consultas externas (A: 0,53% vs. B: 0,34%, p=0,005). Se pudo constatar también que la disminución paralela de las reclamaciones de hospitalización y de consultas externas siguió una correlación lineal significativa (R:0,988 p<0,001).Conclusiones El cambio estructural y funcional por el traslado a un nuevo hospital comportó que el porcentaje de reclamaciones dirigidas al Servicio de CGD disminuyera de manera significativa en el periodo estudiado. Son necesarios estudios prospectivos y multicéntricos que permitan evaluar si estos resultados son superponibles a otros medios (AU)

Objective The complaints to a medical service are a measure of the quality of health care perceived by the patients. The aim of this study was to analyse the differences found in the percentage of complaints made to the General and Gastrointestinal Surgery Department (GGSD) with the changes made due to moving to a new hospital. Material and methods A longitudinal study of the percentage of complaints made to the GGSD in two 6 month periods in the same year (periods A and B). The Department was moved to a new hospital between the two periods. The percentage complaints associated with the hospital and outpatient activity is compared. Results The percentage complaints made to the GGSD was 3.02% directed at the hospital service and 0.44% to outpatient care. When both periods were compared, a statistically significant difference was observed in the hospital complaints (A: 3.74% vs B: 2.20%, P=.006) and in the outpatient complaints (A: 0.53% vs. B: 0.34%, P=.005). It could also be shown that there was a continuous significant correlation in the parallel decrease in the hospital and outpatient complaints (R:0.988P<.001).Conclusions The structural and functional change due to moving to a new hospital showed that the percentage of complaints made to the GGSD changed significantly in the period studied. Prospective multicentre studies are required to evaluate whether these results can be extrapolated to other services (AU)

Prospective analysis of clinician accuracy in the diagnosis of benign anorrectal pathology: the value of clinical information.

AIM: the prevalence of anorectal disorders in general population is high. The aim of this study was to analyze the influence of clinical symptoms on diagnostic accuracy for benign anorectal pathology among different specialists and evaluate the relationship between diagnostic accuracy and years of professional experience. METHODS: seven typical cases were selected. In a first interview, participants were shown images and asked to make a diagnosis. Afterwards, images with additional information (clinical symptoms) were used. Two groups (group 1 = general surgeons and group 2 = medical specialists who attended emergency department) completed both phases of the study to analyze the influence of clinical symptoms on the final diagnosis. RESULTS: forty four specialists were interviewed. The percentage of participants making a correct diagnosis in groups 1 and 2, respectively, was as follows: case 1 (perianal abscess): 100 vs. 80.6%, (p = 0.157); case 2 (fissure): 92.3 vs. 51.6% (p = 0.015); case 3 (thrombosed hemorrhoid): 92.3 vs. 74.2% (p = 0.321); case 4 (anal condyloma): 100 vs. 87.1% (p = 0.302); case 5 (rectal prolapse): 100 vs. 83.9% (p = 0.301); case 6 (prolapsed hemorrhoid): 92.3 vs. 29% (p = 0.001), and case 7 (fistula): 100 vs. 67.7% (p = 0.021). There were significant differences in the number of correctly diagnosed cases between groups (p < 0.001). Information about clinical symptoms significantly increased overall and specific accuracy. There was no correlation between experience and accuracy. CONCLUSIONS: clinical symptoms are important for diagnostic accuracy in anorectal pathology. Training in anorectal pathology in medical specialists is warranted.

Análisis prospectivo de la precisión diagnóstica en la patología anorrectal benigna: importancia de la información clínica / Prospective analysis of clinician accuracy in the diagnosis of benign anorectal pathology: the value of clinical information

Objetivo: la prevalencia de los trastornos anorrectales benignos en la población general es alta. El objetivo de este estudio es analizar la influencia de los síntomas clínicos en la precisión diagnóstica de la patología benigna anorrectal entre los diferentes especialistas y evaluar la relación entre el diagnóstico de la enfermedad y los años de experiencia profesional entre los profesionales participantes. Pacientes y métodos: se seleccionaron 7 casos típicos. En una primera entrevista, se mostró a los participantes las imágenes clínicas de cada caso y se les pidió que formularan un diagnóstico. Posteriormente, se volvió a mostrar las mismas imágenes con información clínica adicional. Dos grupos (grupo 1 = especialistas en cirugía general y digestiva y grupo 2 = especialistas de especialidades médicas con asistencia en el área de urgencias) completaron las dos fases del estudio para analizar la influencia de los síntomas clínicos en el diagnóstico final. También se analizó la relación entre la precisión diagnóstica y los años de experiencia de cada profesional. Resultados: se entrevistaron a 44 especialistas. El porcentaje de participantes que realizó un diagnóstico correcto en el grupo 1 y 2, fue respectivamente: caso 1 (absceso perianal): 100 vs. 80.6%, (p = 0,157); caso 2 (fisura anal): 92,3 vs. 51.6% (p = 0,015); caso 3 (hemorroide trombosada): 92,3 vs. 74,2% (p = 0,321); caso 4 (condiloma anal): 100 vs. 87,1% (p = 0,302); caso 5 (prolapso rectal): 100 vs. 83.9% (p = 0,301); caso 6 (prolapso hemorroidal): 92,3 vs. 29% (p = 0,001), y caso 7 (fístula perianal): 100 vs. 67,7% (p = 0,021). Se observaron diferencias en el número de los diagnósticos correctos entre grupos (p < 0,001). Globalmente, la información sobre síntomas clínicos incrementó significativamente la precisión específicamente, no observándose correlación entre experiencia profesional y precisión. Conclusiones: los síntomas clínicos son importantes para la precisión diagnóstica de la patología anorrectal benigna. La formación específica de especialistas médicos en esta patología anorrectal está claramente justificada(AU)
