Resultados de la resección pulmonar infralobar, comparada con la lobectomía, en el tratamiento quirúrgico del carcinoma broncogénico en estadio precoz / Outcomes of sublobar resection, compared with lobectomy, in the surgical management of early stage non-small cell lung cancer

OBJETIVOS: la resección infralobar (RI) en el carcinoma broncogénico de célula no pequeña (CBCNP) en estadio precoz está ganando popularidad. Sin embargo, la cantidad óptima de parénquima pulmonar a resecar sigue siendo objeto de controversia. Analizamos si la RI difiere de la lobectomía (L) como tratamiento quirúrgico estándar de los pacientes con CBCNP en estadio precoz. MÉTODOS: se analizaron 493 resecciones pulmonares consecutivas realizadas en un periodo de 14 años. 266 pacientes con CBCNP en estadio I fueron sometidos a una lobectomía (L = 178), o a una resección pulmonar atípica/segmentectomía (RI = 88). Se compararon factores demográficos, oncológicos, quirúrgicos y postoperatorios. RESULTADOS: no se observaron diferencias en las características de los pacientes, la mortalidad perioperatoria o la tasa de complicaciones. En los pacientes con CBCNP en estadio I (n = 266) la tasa de recurrencia loco-regional (RI vs L): 14% vs 16% (p = 0,06), metástasis a distancia: 8% vs 9% (p = 0,33), supervivencia (a los 3, 5 años): 78%, 74% vs 74%, 69% (p = 0,37), supervivencia libre de enfermedad (a los 3, 5 años): 82%, 36% vs 80%, 56% (p = 0,93), supervivencia libre de metástasis a distancia (a los 3, 5 años): 90%, 80% vs 86%, 83% (p = 0,73). Complicaciones postquirúrgicas: 30% vs 36% (p = 0,21), mortalidad perioperatoria: 2% vs 5% (p = 0,64). CONCLUSIONES: la resección pulmonar infralobar posee unas tasas aceptables de morbimortalidad y puede ser equivalente a la lobectomía, desde el punto de vista oncológico, en el CBCNP en estadio I

OBJECTIVE: sublobar resection (SLR) for early stage NSCLC is gaining acceptance in the recent years, especially in aging population or with decreased pulmonary function. The optimal extent of surgical resection in stage I NSCLC remains controversial. This study was designed to determine whether SLR differs from lobectomy (L) as the standard of care for the surgical treatment of patients with early stage NSCLC. METHODS: we retrospectively reviewed 493 consecutive lung resections performed over a 5-year period at a single center. A total of 266 patients with NSCLC underwent either lobectomy (L Group: 178 patients), or wedge/segmentectomy (SLR Group: 88 patients) for stage I NSCLC. Demographic, oncological, surgical and postoperative variables were compared between groups. RESULTS: overall, no differences were observed between SLR and L in patient characteristics, 30-day mortality and complications. In stage I patients (n = 266), local recurrence (SLR vs L): 14% vs 16% (p = .06), distant recurrence: 8% vs 9% (p = .33), survival (at 3, 5 years): 78%, 74% vs 74%, 69% (p = .37), local disease-free survival (at 3, 5 years): 82%, 36% vs 80%, 56% (p = .93), distant disease-free survival (at 3, 5 years): 90%, 80% vs 86%, 83% (p = .73). Postoperative complications: 30% vs 36% (p = .21), 30-day mortality: 2% vs 5% (p = .64). CONCLUSION: sublobar resection has acceptable morbidity and mortality rates, and could be oncologically equivalent to lobectomy in stage I NSCLC

Quimerismo donante-receptor como origen del desarrollo de bronquiolitis obliterante en un modelo experimental de retrasplante de tráquea en ratas / Donor-receiver chimerism as the ori gin of obliterative bronchiolitis in an experimental model for trachea re transplant in rats

OBJETIVOS: 1. Desarrollar un modelo de bronquiolitis obli-terante en ratas (BO), mediante trasplante heterotópico de tráquea; 2. Eliminar el componente de rechazo alogénico me-diante el reimplante del injerto en un animal isogénico; y 3. Estudiar la respuesta inflamatoria persistente que podría auto-perpetuar la lesión.MÉTODOS: Se utilizaron ratas de las razas Lewis (LW), Wistar (W) y Brown Norway (BN). Se realizaron trasplantes singéni-cos (LW-LW, n=14; W-W, n=6; y BN-BN, n=6) y alogénicos AB (LW-W, n=6; BN-LW, n=6; y W-LW, n=6), alojando el injerto en el tejido celular subcutáneo cervical. Tras 15 días, se explantó el injerto e implantó en una tercera rata singéni-ca o alogénica por otros 15 días, estableciendo un modelo de retrasplante A-B-A y A-B-B. Los injertos se procesaron para realizar estudios histológicos e inmunohistoquímicos. El ori-gen de las células epiteliales se analizó mediante PCR.RESULTADOS: El retrasplante de tráquea, tanto en el diseño A-B-B como A-B-A, dió lugar a la aparición de una rápida respuesta inflamatoria compatible con un proceso de BO, en aquellos animales que habían desarrollado rechazo por tras-plante alogénico previo. En trasplantes ♀-♂-♀, se detectaron células con el cromosoma Y en tráqueas del 2º receptor ♀.CONCLUSIONES: En el modelo de retrasplante de tráquea en ratas, junto a los hallazgos típicos de BO se produce una res-puesta inflamatoria leve-moderada compatible con un recha-zo celular MHC incompatible. Células procedentes del primer receptor se integrarían en la tráquea del segundo trasplante, produciéndose un quimerismo donante receptor, que sería el responsable, en último término, del desarrollo de BO

OBJECTIVES: 1. Develop an obliterative bronchiolitis (OB) model in rats, by means of heterotopic trachea transplant; 2. Eliminate the allogenic rejection component by re-implanting a graft in an isogenic animal; and 3. Study the persistent in-flammatory response that could self-perpetuate the injury. METHODS: The following rat breeds were used: Lewis (LW), Wistar (W) and Brown Norway (BN). Syngenic (LW-LW, n=14; W-W, n=6; and BN-BN, n=6) and allogenic AB (LW-W, n=6; BN-LW, n=6; and W-LW, n=6) transplants were performed, housing the graft in the cervical subcutaneous ce-llular tissue. After 15 days, the graft was removed and implan-ted into a third syngenic or allogenic rat for another 15 days, to establish a re-transplant model A-B-A and A-B-B. The grafts were processed to carry out histological and immunohistoche-mical studies. The origin of the epithelial cells was analyzed using PCR. RESULTS: The tracheal re-transplant, both in the A-B-B and A-B-A design, gave rise to the appearance of a rapid inflam-matory response compatible with OB process, in those ani-mals that rejected the transplant due to previous allogenic transplant. In ♀ -♂ -♀ transplants, cells were detected with the Y chromosome in trachea of the 2nd ♀ receiver. CONCLUSIONS: In the trachea re-transplant model in rats, together with typical OB discoveries, a compatible slight-moderate inflammatory response takes place with an MHC incompatible cellular rejection. Cells from the first receiver became integrated into the trachea of the second transplant, producing a donor-receiver chimerism that would, in the final location, be responsible for the development of OB. Key words: Lung transplant, chronic rejection, obliterative bronchiolitis, chronic dysfunction of the lung graft

Postoperative complications in the intensive care unit following lung transplantation in adults: results in University Hospital Reina Sofia.

The postoperative period following lung transplantation remains critical because of several complications. Infection, primary graft failure, acute rejection, and surgical complications are risk factors for mortality and morbidity. The recognition and early treatment of these complications is important to optimize outcomes. This article provides an overview of postoperative complications observed in our center during the last year. We were particularly interested in the influence of variables, such as inotrope usage and Acute Physiology and Chronic Health Evaluation (APACHE II) score, a well-known, and validated mortality prediction model for general intensive care unit (ICU) patients only infrequently reported in the transplantation literature. High APACHE II scores were significantly associated with prolonged mechanical ventilation (P = 0.041) and a tracheostomy requirement (P = .035). The factors significantly associated with an early postoperative death were older donor age (P = .005), prolonged donor ICU period (P = .004), need for cardiopulmonary bypass (CB; P = .005), and high inotrope requirements in the ICU (P = .034). CB data were biased because we selected the worst case patients. Donor age and high inotrope requirements in the ICU have been reported previously to be prognostic factors for poor graft function. We believe that control of these variables may improve outcomes.

Combined lung and liver transplantation-University Hospital Reina Sofia experience: two case reports.

OBJECTIVE: To analyze the results of combined lung and liver transplantation. METHODS: We performed two combined lung and liver transplantations for patients with cystic fibrosis with chronic respiratory failure accompanied by advanced liver disease. In each case, all thoracic and abdominal organs were obtained from a single donor by means of standard harvest techniques. In the recipient, a two-stage procedure was adopted with completion of the bilateral lung transplantation before the liver operation. Immunosuppression consisted of three-drug therapy used for isolated lung transplantation. RESULTS: The patients were both boys of 13 and 15 years old. Episodes of acute pulmonary rejection were successfully treated with intravenous steroids. Neither lung disorder was associated with a liver rejection episode. Airway complications that occurred in both cases were managed endoscopically. CONCLUSION: Combined transplantation of lung and liver is a feasible and therapeutically effective procedure for patients with cystic fibrosis complicated by advanced liver disease. Herein we have described our experience in two of the only three cases of combined liver and lung transplantation performed in Spain to date. Patient and graft survivals were comparable to isolated liver or isolated bilateral lung transplantations.

Cirugía broncoplástica en el tumor carcinoide bronquial típico. Descripción de tres casos en la infancia / Bronchoplastic surgery in typical bronchial carcinoid tumour

El tumor carcinoide bronquial típico (TCBT) asienta preferentemente en bronquios de grueso calibre produciendo fenómenos de obstrucción distal. Aunque la OMS lo clasifica dentro de las neoplasias malignas broncopulmonares, el TCBT se muestra poco agresivo y su pronóstico a largo plazo es bueno siempre que no exista diseminación linfática ni metástasis sistémicas. La mayoría de los autores son partidarios del tratamiento quirúrgico conservador, evitando la neumonectomía, siempre que este asegure la total resección del TCBT. Presentamos 3 casos de pacientes infantiles diagnosticados de TCBT en el eje bronquial principal con atelectasia de lóbulos inferiores en los que fue posible la resección con reimplante de lóbulos superiores en 2 casos, y un tercero con tumor en bronquio intermediario, resecándose el mismo con reimplante posterior de lóbulos medio e inferior

The typical bronchial carcinoid tumour (TBCT) is usually located in large bronchi, provoking distal obstruction. Although the WHO classifies it within the malignant bronco-pulmonary neoplasias, TBCT does not always present as very aggressive and its long-term prognosis is good, providing there are no lymphatic dissemination or distant metastasis. Most authors favour conservative surgical treatment, avoiding pneumonectomy, provided this assures the total resection of the TBCT. We present three cases of children diagnosed with TBCT in the main bronchi with atelectasis of the inferior lobes in which resection was possible, together with the re-implantation of the superior lobes in 2 cases. In the third case, the tumour in the intermediary bronchus was resected, with subsequent re-implantation of the midle and inferior lobes

[Simultaneaous bilateral pulmonary metastasectomy of carcinoma of the sweat glands]. / Metastasectomía pulmonar bilateral simultánea de un carcinoma de glándulas sudoríparas.

A 51-year-old woman with carcinoma of the right axillary sweat glands was treated by radical surgery and radiotherapy. Six years later she developed multiple bilateral lung metastases. Nine nodes were resected from both lungs using a clamshell approach (bilateral transsternal, anterolateral thoracotomy). After surgery, the patient received 6 cycles of adjuvant chemotherapy with cisplatin and 5-fluoruracil. Three years after treatment, no intrathoracic recurrences had occurred and the patient was asymptomatic, with good quality of life.

[Spontaneous, massive primary pneumothorax in both lungs]. / Neumotórax espontáneo primario masivo bilateral simultáneo.

Primary spontaneous pneumothorax in both lungs simultaneously is rare. We report the case of a 22-year-old man with no relevant medical history who came to the emergency room in critical condition after suffering simultaneous massive pneumothorax in both lungs. After a pleural drain was inserted in each hemithorax, elective surgery was prescribed because of the bilaterality and severity of the pneumothorax. Sequential video thoracoscopic surgery was performed in a single session, during which small blebs were identified at both lung vertices. The blebs were resected and pleural abrasion performed. Postoperative recovery was unremarkable. The patient was discharged four days after surgery. Five years later, the patient was asymptomatic, having experienced no recurrences.

Metastasectomía pulmonar bilateral simultánea de un carcinoma de glándulas sudoríparas / Simultaneaous bilateral pulmonary metastasectomy of carcinoma of the sweat glands

Mujer de 51 años con un carcinoma de glándulas sudoríparas (CGS) en la axila derecha tratado mediante cirugía radical y radioterapia, que 6 años después presentó metástasis pulmonares bilaterales múltiples. Se resecaron nueve nódulos en ambos pulmones a través de una toracotomía anterolateral bilateral transesternal (clamshell). La paciente recibió seis ciclos de quimioterapia adyuvante postoperatoria con cisplatino y 5-fluorouracilo. En la actualidad, a los 3 años de seguimiento, no ha habido recidivas intratorácicas, y la paciente se encuentra asintomática y con buena calidad de vida (AU)

Neumotórax espontáneo primario masivo bilateral simultáneo / Spontaneous, massive primary pneumothorax in both lungs

El neumotórax espontáneo primario bilateral simultáneo es excepcional. Presentamos el caso de un paciente de 22 años, sin antecedentes de interés, que acudió a urgencias en situación crítica tras sufrir un episodio de neumotórax masivo bilateral simultáneo. Tras la inserción de un drenaje pleural en cada hemitórax, se indicó cirugía electiva definitiva, dada la bilateralidad y gravedad del neumotórax. El paciente fue intervenido mediante cirugía videotoracoscópica bilateral secuencial en la misma sesión operatoria, y se identificaron pequeños blebs en ambos vértices pulmonares. Se realizó una resección de los blebs y una abrasión pleural. El postoperatorio cursó sin incidencias y el enfermo fue dado de alta en el cuarto día postoperatorio. Cinco años después, el paciente se encuentra asintomático sin haber sufrido recurrencia del neumotórax (AU)

[Surgical treatment of cervicomediastinal goiter]. / Tratamiento quirúrgico del bocio cervicomediastínico.

To review our experience with the surgical treatment of cervicomediastinal goiters. Charts of patients with cervicomediastinal goiters undergoing thyroidectomy within the last 10 years were reviewed. Data regarding previous disease, clinical features, diagnostic procedures, surgical intervention and postoperative evolution were recorded. Twenty-eight patients (19 female and 9 male) 62 +/- 2 years old underwent surgery to treat cervicomediastinal goiter during the period reviewed. Among patients with compressive manifestations (75.6%), dyspnea was the most common (36.6%) symptom, followed by dysphagia and superior vena cava syndrome. An extrathoracic obstruction pattern was found in 3 (11.2%) cases. Thyroid scintigraphy showed increased thyroid size in 25 patients, and in 9 of them a cold nodule was present as well. Fine needle aspiration of the thyroid gland was performed in 5 patients; malignancy was found only in 1 case. Fiberoptic bronchoscopy was performed in 15 patients; in 7 (25%) tracheal compression was found. In these patients there was no higher rate of postoperative complications. Cervicotomy was the surgical approach used in 23 (82.1%) patients. Cervicosternotomy was used in 4 (14%), and thoracotomy in 1 (3.6%). The surgical procedure was bilateral subtotal thyroidectomy in 15 (53.6%), total thyroidectomy in 3 (10.7%), right lobectomy in 6 (21.4%), and left lobectomy in 4 (14.3%). Colloid goiter was the most common histological type (42.8%), followed by nodular hyperplasia (35.8%), cancer (10.7%) and adenoma (10.7%). Three patients showed transient recurrent paralysis in the postoperative period, and another 3 patients presented major complications: 1 case of postoperative bleeding and 2 cases of tracheomalacia requiring tracheostomy. Cervicomediastinal goiter is a disease that may involve compressive symptoms. In our experience, most cases were resected through cervicotomy, colloid goiter and the nodular hyperplasia being the most common histological types. There was no relationship between surgical procedure and the incidence of complications.
