Introduction. The pulmonary lobectomies is one of the most common procedures in thoracic surgery in Colombia and worldwide. The objective of this study is to provide information on the clinical behavior of individuals who underwent this type of surgeries. Methods. Retrospective observational study at a University Hospital in Cali, Colombia, including all individuals who had pulmonary lobectomies, between the years 2010 to 2020 for benign and malignant causes. The information was extracted from the institutional registry of thoracic surgery, obtaining demographic, clinical and pathological data. Results. The clinical records of 207 individuals were evaluated, 55.5% were women, the average age was 58 years, and 41% had a history of smoking. Of these cases, 51.6% were diagnosed with neoplasms, of which 47.8% were primary lung neoplasms, with adenocarcinoma being the most common subtype. As for benign diseases, they represented 48.3% of the cases and the most frequent cause was infections, including 17 cases of pulmonary tuberculosis. The most frequent technique was video-assisted thoracoscopic surgery in 82.6%, with a reoperation rate of 5.8%, up to 10.6% of severe complications, a median hospital stay of 6 days, and a hospital mortality of 4.3%.Conclusion. The population evaluated shows a high burden of comorbidities and high operative risk; consequently, when compared with other international series, it shows a higher percentage of perioperative complications, hospital stay, and mortality.

Evaluation of uniportal video-assisted thoracoscopic decortication in treatment of drug-resistant tuberculous empyema / 中华外科杂志

Objective: To examine the safety and efficacy of the uniportal video-assisted thoracoscopic decortication in treatment of drug-resistant tuberculosis empyema. Methods: From January 2018 to December 2020, 122 cases of tuberculous empyema treated by decortication in Department of Surgery, Wuhan Pulmonary Hospital were retrospectively analyzed, including 100 males and 22 females, aged(M(IQR)) 29.5(28.0) years (range: 13 to 70 years). According to the surgical approach and drug resistance, patients with drug-resistant tuberculosis who underwent uniportal video-assisted thoracoscopic decortication were included in group A (n=22), and those who underwent thoracotomy decortication were included in group B (n=28). Drug-sensitive patients who underwent uniportal video-assisted thoracoscopic decortication were included in group C (n=72). There was no statistical difference in the baseline data of the three groups (P>0.05). The operation, early postoperative recovery, and prognosis-related indicators were compared among three groups by Kruskal-Wallis test and χ2 test by Mann-Whitney U test and Bonferroni method between groups A and B, groups A and C. Results: The intraoperative blood loss of group A, group B, and group C was 200(475) ml, 300(200) ml, and 225(300) ml, respectively. There was no significant difference in intraoperative hemorrhage (H=2.74, P=0.254) and treatment outcome (χ2=4.76, P=0.575) among the three groups. Compared with group B, the operation time of group A (302.5(187.5) minutes vs. 200.0(60.0) minutes, U=171.0, P=0.007) and postoperative pulmonary reexpansion duration (4.5(3.0) months vs. 3.0 (2.2) months, U=146.5, P=0.032) were longer, and the postoperative drainage duration (9.5(7.8) days vs. 13.0(10.0) days, U=410.0, P=0.044), and the postoperative hospitalization time (12.0(7.8) days vs. 14.5(4.8) days, U=462.2, P=0.020) were shorter. There was no significant difference in complications between group A and group B (63.6%(14/22) vs. 71.4%(20/28), χ2=0.34, P=0.558). Compared with group C, the postoperative drainage duration of group A (9.5(7.8) days vs. 7.0(4.0) days, U=543.5, P=0.031), the postoperative hospitalization time (12.0(7.8) days vs. 9.0(4.0) days, U=533.0, P=0.031) and postoperative pulmonary reexpansion duration (4.5(3.0) months vs. 3.0(2.0) months, U=961.5, P=0.001) were longer. The operation time (302.5(187.5) minutes vs. 242.5(188.8) minutes, U=670.5, P=0.278), and complications (63.6%(14/22) vs. 40.3%(29/72), χ2=3.70, P=0.054) were not different between group A and group C. Conclusions: For drug-resistant tuberculous empyema, the uniportal video-assisted thoracoscopic decortication can achieve the same good therapeutic effect as drug-sensitive tuberculous empyema, and it is as safe as thoracotomy. At the same time, it has the advantage of minimally invasive and can accelerate the early postoperative recovery of patients.

Analgesic effect of intercostal nerve block given preventively or at the end of operation in video-assisted thoracic surgery: a randomized clinical trial

Abstract Objective To compare the analgesic effect of intercostal nerve block (INB) with ropivacaine when given preventively or at the end of the operation in patients undergoing video-assisted thoracic surgery (VATS). Methods A total of 50 patients undergoing VATS were randomly divided into two groups. The patients in the preventive analgesia group (PR group) were given INB with ropivacaine before the intrathoracic manipulation combined with patient-controlled analgesia (PCA). The patients in the post-procedural block group (PO group) were administered INB with ropivacaine at the end of the operation combined with PCA. To evaluate the analgesic effect, postoperative pain was assessed with the visual analogue scale (VAS) at rest and Prince Henry Pain Scale (PHPS) scale at 6, 12, 24, 48, and 72 hours after surgery. Results At 6 h and 12 h post-surgery, the VAS at rest and PHPS scores in the PR group were significantly lower than those in the PO group. There were no significant differences in pain scores between two groups at 24, 48, and 72 hours post-surgery. Conclusion In patients undergoing VATS, preventive INB with ropivacaine provided a significantly better analgesic effect in the early postoperative period (at least through 12 h post-surgery) than did INB given at the end of surgery.

Tratamiento del secuestro pulmonar en niños: resección quirúrgica versus embolización endovascular / Treatment of pulmonary sequestration in children: surgical resection versus endovascular embolization

Introducción: El secuestro pulmonar es una malformación del tracto respiratorio inferior, que consiste en una masa no funcional de tejido pulmonar sin comunicación con el árbol traqueobronquial y su irrigación sanguínea proviene de una o más arterias sistémicas aberrantes. El objetivo del presente estudio fue analizar los resultados de los pacientes pediátricos con secuestro pulmonar tratados con resección quirúrgica (toracotomía, videotoracoscopía) o embolización endovascular. Metodología: estudio descriptivo, observacional, retrospectivo, de corte transversal, realizado en un hospital pediátrico de tercer nivel en Ecuador, desde enero de 2017 a diciembre de 2022. Los datos fueron obtenidos de las historias clínicas revisadas. Resultados: Se incluyeron 9 pacientes, menores de 18 años con el diagnóstico de secuestro pulmonar, 6 femenino y 3 masculino, 5 fueron tratados con cirugía, 4 (44%) por toracotomía y 1 (11%) por videotoracoscopía, 4 (44%) con embolización endovascular, la edad promedio de los pacientes sometidos a cirugía fue de 41.36 (rango: 0.1-144 meses), y de los que recibieron embolización fue de 12.9 meses (rango: 0.6-41 meses). un paciente falleció 6 días posterior a la resección quirúrgica del secuestro pulmonar por toracotomía debido a hipertensión pulmonar por su cardiopatía de base y 1 paciente tratado con embolización presento disminución del pulso pedio el cual se resolvió a las 24 horas de iniciada la estreptoquinasa. Conclusión: Hasta donde hemos investigado no hemos encontrado otra publicación en nuestro país en donde se comparen dos métodos terapéuticos para el tratamiento del secuestro pulmonar. En este estudio tanto la cirugía como la embolización fueron procedimientos seguros; no se encontró diferencias significativas entre ambas opciones terapéuticas, es necesario estudios con mayor población y con características prospectivas en los pacientes tratados por embolización endovascular.

Cohort study on 20 years' experience of bilateral video-assisted thoracic sympathectomy (VATS) for treatment of hyperhidrosis in 2431 patients

Abstract BACKGROUND: Primary hyperhidrosis is a condition characterized by excessive sweating, inconsistent with the needs for thermoregulation. OBJECTIVE: To assess the effectiveness and the change in the quality of life of patients undergoing bilateral VATS (video-assisted thoracoscopic sympathectomy) for treatment of hyperhidrosis, in a large case series. DESIGN AND SETTING: Cohort study conducted in a tertiary hospital specializing in hyperhidrosis located in São Paulo, Brazil. METHODS: A total of 2,431 patients who underwent surgery consisting of bilateral video-assisted thoracoscopic sympathectomy between January 2000 and February 2017 were retrospectively assessed in an outpatient clinic specializing in hyperhidrosis. The patients underwent clinical and quality of life assessments on two occasions: firstly, prior to surgery, and subsequently, one month after the operation. The presence or absence of compensatory hyperhidrosis (CH) and general satisfaction after the first postoperative month were also evaluated. RESULTS: All the patients operated had poor or very poor quality of life before surgery. In the postoperative period, an improvement in the quality of life was observed in more than 90% of the patients. Only 10.7% of the patients did not present CH, and severe CH occurred in 22.1% of the patients in this sample. CONCLUSION: Bilateral VATS is a therapeutic method that decreases the degree of sweating more than 90% of patients with palmar and axillary hyperhidrosis. It improves the quality of life for more than 90% of the patients, at the expense of development of CH in approximately 90% of the patients, but not intensely.

Single-versus Two-port Video-assisted Thoracic Surgery in Thymoma: A Propensity-matched Study / 中国肺癌杂志

BACKGROUND@#In recent years, with the advancement of minimally invasive techniques, thoracoscopic thymoma resection has experienced a development process from three-port video-assisted thoracic surgery (VATS) to two-port (TP) and single-port (SP) variants. However, the feasibility and safety of SP-VATS have not been generally recognized. This study intends to explore the safety and feasibility of SP-VATS in thymoma resection, in order to provide a reference for clinical surgicalselection.@*METHODS@#The clinical data of 197 patients who underwent thoracoscopic thymoma resection in Beijing Tongren Hospital from January 2018 to September 2021 were retrospectively analyzed. The patients were divided into SP-VATS group (n=42) and TP-VATS group (n=155). After matching propensity scores, there is no statistically significant difference in preoperative baseline data between SP-VATS group and TP-VATS group. Among them, there were 17 males and 25 females with an average age of 28-72 (48.00±9.43) years in the SP-VATS group, and 20 males and 22 females with an average age of 30-75 (50.38±9.83) years in TP-VATS group. The clinical effects of the two groups were compared.@*RESULTS@#The operation was successfully completed in both groups, and there was no conversion to thoracotomy or increased surgical incisions. Compared with the TP-VATS group, the chest drainage time and hospital stay in the SP-VATS group were shorter [(2.95±0.76) d vs (3.33±0.85) d; (4.57±0.83) d vs (5.07±1.13) d], and the visual pain score at 24 h and 72 h after surgery were lower [(3.64±0.85) points vs (4.05±0.66) points; (2.33±0.75) points vs (3.07±0.68) points] (P<0.05). There was no statistically significant difference between the two groups in operation time [(130.00±26.23) min vs (135.24±27.03) min], intraoperative blood loss [(69.52±22.73) mL vs (82.38±49.23) mL] (P>0.05).@*CONCLUSIONS@#SP-VATS in thymoma is a safe, feasible, and less invasive procedure, with less postoperative pain and faster recovery than multi-port VATS.

Application of CT-guided Localization with Medical Glue for Single and Two or More Small Pulmonary Nodules before Video-assisted Thoracic Surgery / 中国肺癌杂志

BACKGROUND@#The localization of pulmonary nodules is related to whether the lesions can be found and removed accurately and quickly. It is an important link for the success of minimally invasive video-assisted thoracic surgery (VATS). This study investigated the feasibility of medical glue localization under VATS video-assisted thoracoscopic computed tomography (CT) guidance for single pulmonary nodule and more than two pulmonary nodules, and compared with the accuracy and safety of single nodule localization.@*METHODS@#A retrospective analysis of the clinical data of patients who underwent unilateral CT-guided medical glue localization before VATS from November 2018 to March 2021 were performed, the patients was divided into multiple pulmonary nodules group (localized nodules ≥2) and single pulmonary nodule group according to the number of localized nodules. The localization time, success rate and complication rate of the two groups were compared.@*RESULTS@#There were 126 nodules in the two groups, including 62 in single pulmonary nodule group and 64 in multiple pulmonary nodules group. The average single nodule localization time was (13.23±4.5) min in single pulmonary nodule group and (10.52±2.8) min in multiple pulmonary nodules group, the difference between the two groups is statistically significant (P<0.05). The localization success rate of single pulmonary nodule group and multiple pulmonary nodules group were 100% and 98.4% separately, the difference between the two groups was not statistically significant (P>0.05). All VATS were successfully completed after localization. The incidence of pneumothorax was higher in multiple pulmonary nodules group than in single pulmonary nodule group (P=0.07).@*CONCLUSIONS@#Compared with localization of single lung nodule, unilateral CT-guided medical glue localization for multiple pulmonary nodules before VATS is also feasible and accuracy, it is worthy of clinical application. But the higher rate of pneumothorax should be paid attention to.

Effect of ulinastatin on the inflammatory response after video-assisted thoracic lobectomy in patients with lung cancer: a randomized controlled study / 中华医学杂志(英文版)

BACKGROUND@#The first-line treatment for lung cancer is surgical resection, and one-lung ventilation (OLV) is the most basic anesthetic management method in lung surgery. During OLV, inflammatory cytokines are released in response to the lung tissue damage and promote local and contralateral lung damage through the systemic circulation. We designed a randomized, prospective study to evaluate the effect of the urinary trypsin inhibitor (UTI) ulinastatin on the inflammatory response after video-assisted thoracic lobectomy in patients with lung cancer.@*METHODS@#Adult patients aged 19 to 70 years, who were scheduled for video-assisted thoracic lobectomy surgery to treat lung cancer between May 2020 and August 2020, were enrolled in this randomized, prospective study. UTI (300,000 units) mixed with 100 mL of normal saline in the ulinastatin group and 100 mL of normal saline in the control group was administered over 1 h after inducing anesthesia.@*RESULTS@#The baseline (T0) interferon-γ (IFN-γ)/interleukin-4 (IL-4) ratio was not different between the groups (6941.3 ± 2778.7 vs. 6954.3 ± 2752.4 pg/mL, respectively; P  > 0.05). The IFN-γ/IL-4 ratio was significantly higher in ulinastatin group at 30 min after entering the recovery room than control group (20,148.2 ± 5054.3 vs. 6674.0 ± 2963.6, respectively; adjusted P < 0.017).@*CONCLUSION@#Administering UTI attenuated the anti-inflammatory response, in terms of INF-γ expression and the IFN-γ/IL-4 ratio, after video-assisted thoracic surgery in lung cancer patients.@*TRIAL REGISTRATION@#Clinical Research Information Service of Korea National Institute of Health (CRIS), KCT0005533.

Uniportal thoracoscopic decortication for stage Ⅲ tuberculous empyema of 158 cases / 中华外科杂志

Objective: To examine the safety and feasibility of uniportal video-assisted thoracoscopic (VATS) decortication in patients presenting with stage Ⅲ tuberculous empyema. Methods: From August 2017 to July 2020, 158 patients of stage Ⅲ tuberculous empyema underwent uniportal VATS decortication with partial rib resection and customized periosteal stripper in Department of Thoracic Surgery, Shanghai Pulmonary Hospital. There were 127 males and 31 females, aged (M(IQR)) 32(28) years (range:14 to 78 years). Follow-up was performed in the outpatient clinic or via social communication applications, at monthly thereafter. If there was no air leak and chest tube drainage was less than 50 ml/day, a chest CT was performed. If the lung was fully re-expanded, chest tubes were removed. All patients received a follow-up chest CT 3 to 6 months following their initial operations which was compared to their preoperative imaging. Results: There was one conversion to open thoracotomy. The operative time was 2.75 (2.50) hours (range: 1.5 to 7.0 hours), and median blood loss was 100 (500) ml (range: 50 to 2 000 ml). There were no perioperative mortalities. There were no major complications except 1 case of redo-VATS for hemostasis due to excessive drainage and 1 case of incision infection, The incidence of prolonged air leaks (>5 days) was 80.3%(126/157). The postoperative hospital stay was 5.00 (2.25) days (range: 2 to 15 days). All patients were discharged with 2 chest tubes, and the median duration drainage was 21.00 (22.50) days (range: 3 to 77 days). Follow-up was completed in all patients over a duration of 20 (14) months (range: 12 to 44 months). At follow-up, 149 patients(94.9%) recovered to grade Ⅰ level, 7 patients to grade Ⅱ level, and 1 patient to grade Ⅲ level. Conclusion: Uniportal VATS decortication involving partial rib resection and a customized periosteal stripper is safe and effective for patients with stage Ⅲ tuberculous empyema.

Video-Assisted Thoracoscopy For Penetrating Cardiac Box Injury in Stable Patients

Abstract Introduction: In high-volume trauma centers, especially in developing countries, penetrating cardiac box injuries are frequent. Although many aspects of penetrating chest injuries have been well established, video-assisted thoracoscopy is still finding its place in cardiac box trauma and algorithmic approaches are still lacking. The purpose of this manuscript is to provide a streamlined recommendation for penetrating cardiac box injury in stable patients. Methods: Literature review was carried out using PubMed/MEDLINE and Google Scholar databases to identify articles describing the characteristics and concepts of penetrating cardiac box trauma, including the characteristics of tamponade, cardiac ultrasound, indications and techniques of pericardial windows and, especially, the role of video-assisted thoracoscopy in stable patients. Results: Penetrating cardiac box injuries, whether by stab or gunshot wounds, require rapid surgical consultation. Unstable patients require immediate open surgery, however, determining which stable patients should be taken to thoracoscopic surgery is still controversial. Here, the classification of penetrating cardiac box injury used in Colombia is detailed, as well as the algorithmic approach to these types of trauma. Conclusion: Although open surgery is mandatory in unstable patients with penetrating cardiac box injuries, a more conservative and minimally invasive approach may be undertaken in stable patients. As rapid decision-making is critical in the trauma bay, surgeons working in high-volume trauma centers should expose themselves to thoracoscopy and always consider this possibility in the setting of penetrating cardiac box injuries in stable patients, always in the context of an experienced trauma team.

Survival outcome of pulmonary metastasectomy among the patients with colorectal cancers

SUMMARY OBJECTIVE: Pulmonary metastasectomy for the treatment of metastatic colorectal cancer is essential, but high ranked evidence of survival benefit is lacking. Here, we aimed to examine the prognostic factors after pulmonary metastasectomy in patients with colorectal cancer. METHODS: This is a single-center, retrospective hospital-based observational case series study. We reviewed data for 607 patients with metastatic colorectal cancer (mCRC) who were treated and observed from 2012 to 2019. Of the 607 patients with mCRC, 87 were with solitary lung metastases. Of the 87 patients, 39 were not appropriate for metastasectomy, while 15 patients recognized as suitable candidates by the multidisciplinary thoracic tumor board rejected metastasectomy. Consequently, only 33 patients were included in the final analysis. RESULTS: Rectum was detected as the primary site in 16 (48.5%) patients. Over 80% of patients had metachronous lung metastases, with a median of 29.0 months from initial diagnosis. Video-assisted thoracic surgery with wedge resection was performed in 20 (60.6%) patients. Over 90% of patients had solitary metastasis resected, with 97% of R0 resection. Median tumor size was 23.0 mm (min: 10; max: 90). Adjuvant treatment was given to 31 (93.9%) patients, while neoadjuvant treatment was given only to 8 (25%) patients. Of the 33 patients, there were 25 (75.7%) relapses. The most frequent site of relapse was lung in 15 (45.5%) patients. Interestingly, there were only 4 (12.2%) patients who had a relapse in the liver after lung metastasectomy. We found that median disease-free survival (DFS) and overall survival (OS) were 43.0 (13.0-73.0) and 55.0 (31.6-78.4) months, respectively. CONCLUSIONS: Pulmonary metastasectomy was associated with significantly long-time survival rates in mCRC (43 months of DFS and 55 months of OS). The second relapse occurred in 25 (75.7%) patients, with isolated lung metastases in nearly half of the patients (45.5%). Therefore, lung metastases in mCRC were unique and a multidisciplinary team including a thoracic surgeon should manage these patients.

The role of the surgeon in treating patients with lung cancer. An updating article

ABSTRACT Lung cancer is a type of neoplasia with one of the highest incidences worldwide and is the largest cause of mortality due to cancer in the world today. It is classified according to its histological and biological characteristics, which will determine its treatment and prognosis. Non-small cell lung cancer accounts for 85% of the cases, and these are the cases that surgeons mostly deal with. Small cell lung cancer accounts for the remaining 15%. Surgery is the main method for treating early stage lung cancer, and lobectomy is the preferred procedure for treating primary lung cancer, while sublobar resection is an alternative for patients with poor reserve or with very small tumors. Surgeons need to be trained to use the resources and techniques available for lung resection, including less invasive approaches such as video-assisted thoracoscopic surgery (VATS) and robotic-assisted thoracoscopic surgery (RATS), and need to be familiar with new oncological approaches, including curative, adjuvant or palliative treatments for patients with lung cancer.

INTRODUCCIÓN: en la actualidad no existe un consenso respecto al manejo de los nódulos pulmonares subsólidos (NPSS). OBJETIVO: describir los resultados del manejo quirúrgico de los NPSS, basados en un algoritmo local. MATERIAL Y MÉTODOS: estudio descriptivo de corte transversal. Se revisaron las fichas clínicas electrónicas de los pacientes operados por NPSS, sugerentes de ser malignos, a juicio de un equipo multidisciplinario, entre enero de 2014 y enero de 2018, en el Departamento de Cirugía de Adultos de Clínica Las Condes. RESULTADOS: se estudió un total de 35 pacientes. La edad promedio fue de 65,8 años. El tamaño promedio de los nódulos fue de 15 mm. Todos los pacientes fueron abordados por cirugía videotoracoscópica asistida. El 88,6% de las biopsias demostró la presencia de una neoplasia maligna. CONCLUSIONES: la adopción de un algoritmo local, instituido por un equipo multidisciplinario, es una alternativa para el manejo adecuado de los portadores de NPSS.

BACKGROUND: Nowadays, there is no consensus in the management of pulmonary subsolid nodules (SSNs). AIM: describe the results of surgical management of SSNs, based on institutional algorithm. MATERIAL AND METHODS: cross-sectional, descriptive study, with revision of clinical electronic records, that included all patients intervened for SSNs, suggestive of malignancy, by the judgment of a multi-disciplinary team, from January 2014 to January 2018 at the Department of Adult Surgery, Clinica Las Condes. RESULTS: 35 patients were studied. The average age was 65.8 years. The average size of the nodules was 15 mm. All patients were approached by video-assisted thoracoscopic surgery. 88.6% of biopsies turned out to be malignant neoplasm. CONCLUSIONS: the acquisition of a local algorithm established by a multidisciplinary team is an appropriate alternative for the management of the patients with SSNs.

Introduction: Single-port Video Assisted Thoracic Surgery (Uniportal VATS) has currently become one of the most commonly used approaches for lung resections in many Thoracic Surgery Centers around the world. In Cuba, its introduction is quite recent and it is still in its initial phase. Objective: To compare the results obtained by open thoracic surgery and Uniportal VATS in patients who underwent surgery in the National Institute of Oncology and Radiobiology of Havana (INOR) from January 2016 to April 2017. Material and Methods: An observational descriptive longitudinal retrospective study was conducted in 60 patients who underwent Thoracic Surgery in the INOR during 2016 - April 2017. Results: A total of 24 patients were operated through Uniportal VATS and 36 underwent thoracotomy. The lesions predominantly affected the right side and lobectomy was the most performed surgical procedure. Stages IA and IB predominated. Most of the procedures were carried out in 3 hours or less, 8 cases were converted and 13 suffered from complications. The average postoperative length of stay in hospital for patients who underwent Uniportal VATS was reduced compared to those who underwent open thoracotomy. Conclusions: Uniportal VATS is characterized by being a safe procedure with few complications and great versatility. It improves postoperative recovery of patients and accelerates their return to daily life activities(AU)

Benefit of video-assisted thoracic surgery in the emergency of a complicated postpartum diaphragmatic hernia / Beneficio de la cirugía torácica video-asistida en la emergencia de una hernia diafragmática posparto complicada

Abstract Diaphragmatic hernia during pregnancy or puerperium are rare entities that, in the event of a complication, represent a life-threatening emergency for both mother and the unborn child. Resolution in many cases requires a combined access through the thoracic and abdominal cavity to manage the complica tions of necrosis and/or perforation of an abdominal viscera. To treat the thoracic cavity, thoracotomy is the most described approach. Even more, the minimally invasive access by video-assisted thoracic surgery (VATS) is not widely referenced in the literature despite its clear benefits of this technique in the recovery of patients, even in emergencies. We present the case of a postpartum right diaphragmatic hernia, complicated by necrosis of the colonic wall, treated by combined VATS approach and laparotomy in the emergency.

Resumen Las hernias diafragmáticas durante el embarazo o puerperio son entidades raras que, en caso de complicación, representan una emergencia potencialmente mortal tanto para la madre como para el feto. La resolución en muchos casos requiere un acceso combinado a través de la cavidad torácica y abdominal para manejar las complicaciones de la necrosis o perforación de las vísceras abdominales. Para tratar la cavidad torácica, la toracotomía es la vía más descrita. Más aún, el acceso mínimamente invasivo mediante cirugía torácica video-asistida (VATS) no está ampliamente referenciado en la literatura a pesar de los claros beneficios de esta técnica en la recuperación de los pacientes, incluso en emergencias. Presentamos el caso de una hernia diafragmática derecha posparto, complicada por necrosis de la pared colónica, tratada combinado VATS y laparotomía en la urgencia.
