Surgical treatment for colorectal cancer: analysis of the influence of an enhanced recovery programme on long-term oncological outcomes-a study protocol for a prospective, multicentre, observational cohort study.

INTRODUCTION: The evidence currently available from enhanced recovery after surgery (ERAS) programmes concerns their benefits in the immediate postoperative period, but there is still very little evidence as to whether their correct implementation benefits patients in the long term. The working hypothesis here is that, due to the lower response to surgical aggression and lower rates of postoperative complications, ERAS protocols can reduce colorectal cancer-related mortality. The main objective of this study is to analyse the impact of an ERAS programme for colorectal cancer on 5-year survival. As secondary objectives, we propose to analyse the weight of each of the predefined items in the oncological results as well as the quality of life. METHODS AND ANALYSIS: A multicentre prospective cohort study was conducted in patients older than 18 years of age who are scheduled to undergo surgery for colorectal cancer. The study involved 12 hospitals with an implemented enhanced recovery protocol according to the guidelines published by the Spanish National Health Service. The intervention group includes patients with a minimum implementation level of 70%, and the control group includes those who fail to reach this level. Compliance will be studied using 18 key performance indicators, and the results will be analysed using cancer survival indicators, including overall survival, cancer-specific survival and relapse-free survival. The time to recurrence, perioperative morbidity and mortality, hospital stay and quality of life will also be studied, the latter using the validated EuroQol Five questionnaire. The propensity index method will be used to create comparable treatment and control groups, and a multivariate regression will be used to study each variable. The Kaplan-Meier estimator will be used to estimate survival and the log-rank test to make comparisons. A p value of less than 0.05 (two-tailed) will be considered to be significant. ETHICS AND DISSEMINATION: Ethical approval for this study was obtained from the Aragon Ethical Committee (C.P.-C.I. PI20/086) on 4 March 2020. The findings of this study will be submitted to peer-reviewed journals (BMJ Open, JAMA Surgery, Annals of Surgery, British Journal of Surgery). Abstracts will be submitted to relevant national and international meetings. TRIAL REGISTRATION NUMBER: NCT04305314.

Vía totalmente extraperitoneal extendida (eTEP) para la corrección de hernias ventrales: resultados preliminares / Extended Totally Extraperitoneal (eTEP) Approach for Ventral Hernia Repair: Initial Results

INTRODUCCIÓN: Desde la primera eventroplastia laparoscópica se han desarrollado múltiples procedimientos en cirugía miniinvasiva de la pared abdominal. En 2017 se publica el acceso endoscópico totalmente extraperitoneal extendido (eTEP) para la reparación abdominal. Se presentan los resultados de la implementación de la técnica en 2 centros por un único cirujano. MÉTODOS: Estudio prospectivo descriptivo de la implementación de la vía eTEP con o sin liberación de transverso (TAR) para defectos de la pared abdominal. La técnica quirúrgica se inicia con el acceso al espacio entre el músculo recto y la vaina posterior, uniendo dicho espacio con el preperitoneo de la línea media y el espacio retrorrectal contralateral. En la cavidad creada se realiza la disección y reducción del saco herniario. Se puede realizar adicionalmente una liberación posterior de componentes tipo TAR. Se realiza el cierre del peritoneo y del defecto fascial y se extiende una prótesis en el espacio definitivo. RESULTADOS: Se intervinieron 40 casos, 20 casos con defectos supraumbilicales, 10 casos infraumbilicales y 10 en la línea semilunar. Dieciséis casos asociaron TAR. El tiempo quirúrgico medio fue de 126 minutos. El dolor mediano por la escala EVA al alta fue de 3. La estancia mediana fue de un día y el seguimiento medio de 10 meses. Un caso mostró recidiva y 2 pacientes requirieron reintervención. CONCLUSIONES: La reparación de hernias primarias e incisionales abdominales mediante eTEP es segura y reproducible. Los resultados preliminares muestran buen control del dolor postoperatorio y baja estancia

INTRODUCTION: Since the first laparoscopic incisional hernia repair, several minimally invasive procedures have been developed in abdominal wall repair. In 2017, the extended totally extraperitoneal (eTEP) approach for abdominal wall repair was published. We present the results from eTEP implementation at two medical centers by one surgeon. METHODS: Prospective descriptive study of the implementation of the eTEP approach, with transversus abdominis release (TAR) when needed. The surgical technique was initiated by accessing the space between the rectus abdominis muscle and posterior rectus sheath, connecting this space with the fatty preperitoneal space at the midline and the contralateral retrorectal space. Identification and dissection of the hernia sac is performed in the created cavity. Additionally, posterior component release in a TAR fashion could be done. Finally, closure of posterior plane and linea alba is completed and mesh prosthesis is deployed along the whole dissected space. RESULTS: Forty patients underwent an eTEP procedure with 20 supraumbilical defects, 10 infraumbilical and 10 lateral hernias. Sixteen cases required a TAR technique. Mean operative time was 126 minutes. Median pain reported the first postoperative day was 3 on the visual analogue scale. Median length of stay was 1 day and mean follow-up was 10 months. Only one patient developed recurrence, and two patients underwent reoperation. CONCLUSIONS: Implementation of eTEP in abdominal wall repair is safe. Preliminary outcomes of the eTEP approach in ventral hernia repair show good pain control with less hospital stay

[Choriocarcinoma of the lung]. / Coriocarcinoma de pulmón.

Primary choriocarcinoma of the lung is an extremely rare condition with a fatal outcome in most patients. We report the case of a 31-year-old woman with cough, chest pain, and hemoptysis, whose chest radiograph displayed nodules in the right upper lobe. After study and an unsuccessful attempt at histological characterization of the lesions, exploratory surgery was indicated. The patient underwent lobectomy and lymphadenectomy after diagnosis of a malignant process in the intraoperative biopsy. The definitive diagnosis was choriocarcinoma. Gonadal involvement was ruled out and the patient was referred to the oncology department for adjuvant therapy. She remains free of disease after 42 months. Although choriocarcinoma of the lung is extremely rare and it is hard to establish a standard treatment, in cases of localized disease, surgical resection followed by chemotherapy seems to be useful and can achieve long survivals.

Coriocarcinoma de pulmón / Choriocarcinoma of the Lung

El coriocarcinoma primitivo de pulmón es una entidad extraordinariamente infrecuente, con evolución fatal en la mayoría de los pacientes. Se presenta el caso de una mujer de 31 años con tos, dolor torácico y hemoptisis, en cuya radiografía se apreciaron nódulos en el lóbulo superior derecho. Tras estudio e intento de filiación histológica de las lesiones, sin resultado, se indicó exploración quirúrgica y se practicó una lobectomía más linfadenectomía tras el diagnóstico de malignidad en la biopsia perioperatoria. El diagnóstico definitivo fue de coriocarcinoma. Se descartó que hubiera afectación ginecológica y se remitió a la paciente a oncología para tratamiento complementario. No hay evidencia de enfermedad a los 42 meses.Si bien esta enfermedad es muy rara y resulta difícil establecer un tratamiento estandarizado, en la enfermedad localizada parece útil la resección quirúrgica seguida de quimioterapia, con las que pueden conseguirse supervivencias elevadas(AU)
