The modified Lyon's position: an alternative approach to robotic thymectomy

The conventional supine position for robotic thymectomy may present challenges in accessing the lower thymic horns, particularly in cases requiring extensive resection of mediastinal fat. To address this issue, the authors advocate for a lateral patient position during the procedure, emphasizing optimized access to the thymic horns and improved procedural efficacy. The lateral approach involves specific trocar placements and port arrangements to minimize conflicts between instruments. This report proposes an innovative approach to robotic thymectomy for patients diagnosed with thymoma or thymic hyperplasia associated with myasthenia gravis.

Analysis of predictive factors of unforeseen nodal metastases in resected clinical stage I NSCLC

Background

Despite notable advances made in preoperative staging, unexpected nodal metastases after surgery are still significantly detected. In this study we aim to analyze the upstaging rate in patients with clinical stage I NSCLC without evidence of nodal disease in the preoperative staging who underwent lobectomy and radical lymphadenectomy.

Methods

Patients who underwent lobectomy and systematic lymphadenectomy for clinical stage I NSCLC were evaluated. Exclusion criteria included the neoadjuvant treatment, incomplete resection and no adherence to preoperative guidelines.

Results

A total of 297 patients were included in the study. 159 patients were female, and the median age was 68 (61 - 73). The variables that showed a significant correlation with the upstaging rate at the univariate analysis were the number of resected lymph nodes and micropapillar/solid adenocar-cinoma subtype. This result was confirmed in the multivariate analysis with a OR= 2.545 (95%CI 1.136-5.701; p=0.02) for the number of resected lymph nodes and a OR=2.717 (95%CI 1.256-5.875; p=0.01) for the high-grade pattern of adenocarcinoma.

Conclusion

Our results showed that in a homogeneous cohort of patients with clinical stage I NSCLC, the number of resected lymph nodes and the histological subtype of adenocarcinoma can significantly be associated with nodal metastasis.

Multimodal evaluation of locoregional anaesthesia efficacy on postoperative pain after robotic pulmonary lobectomy for NSCLC: a pilot study

The primary objectives of the study were to analyse the robotic approach and ultrasound-guided paravertebral block compared to thoracoscopic intercostal nerve block after robotic pulmonary lobectomy on postoperative pain and opioids use. The secondary objectives were to analyse and compare patients' necessity of additional antalgic drugs and patients' performance during respiratory therapy, following robotic surgery and in the two groups. Consecutively, 52 patients undergoing robotic pulmonary lobectomies were treated either with ropivacaine-based intercostal nerve block or paravertebral block from February 2022 to October 2022. When necessary, morphine was administered at day 1. Acetaminophen was administered as an additional antalgic drug on demand up to 3 g per day. Pain was measured 1 h after the end of the surgical procedure and daily through the pain numeric rating scale (NRS). Morphine administration rate and per day and total additional administrations of acetaminophen were recorded. Pain and opioids administration was measured 1 month after the procedure. Data were analysed in the overall population and in the intercostal nerve block group VS paravertebral block group. Overall, 34.6% of the patients required morphine administration and 51.7% of the patients required at least daily acetaminophen administration up to discharge. At 1 month postoperatively, four patients presented with chronic pain and one still was under opioid medication. At intergroup analysis, the paravertebral block group demonstrated lower NRS at fixed time points (p < 0.0001) and lower morphine consumption (45.7%VS11.8%; p = 0.02). Acetaminophen rescue administration at fixed time points was lower in the paravertebral block group (p < 0.0001) and mobility and dynamic pain resulted in better results (p = 0.03; p = 0.04). At 1 month, no differences were found between study groups. Similarly to other minimally invasive techniques, postoperative pain may arise after robotic pulmonary lobectomy. Paravertebral bloc can help to reduce postoperative pain as well as morphine and antalgic drugs administration and improve early mobilization.

Robotic Lobectomy without Complete Fissure for Non-Small Cell Lung Cancer: Technical Aspects and Perioperative Outcomes of the Tunnel Technique

Even though the use of the "fissure-last" technique in mini-invasive lobectomy with the fissureless condition is well accepted, in terms of perioperative outcomes, controversies still surround the hilar lymph node dissection. In this article, we reported a description of the robotic "tunnel technique" approach in the right upper lobectomy in the absence of a defined fissure. We then compared the short terms outcomes of 30 consecutive cases treated using this technique, with 30 patients treated using the "fissure last" VATS approach in the same institution, before the start of the robotic surgery program.

KRAS G12C mutation and risk of disease recurrence in stage I surgically resected lung adenocarcinoma

KRAS G12C mutations are found in about 12-13% of LUAD samples and it is unclear whether they are associated with worse survival outcomes in resected, stage I LUAD. We assessed whether KRAS-G12C mutated tumours had worse DFS when compared to KRAS-nonG12C mutated tumours and to KRAS wild-type tumours in a cohort of resected, stage I LUAD (IRE cohort). We then leveraged on publicly available datasets (TCGA-LUAD, MSK-LUAD⁶⁰⁴) to further test the hypothesis in external cohorts. In the stage I IRE cohort we found a significant association between the KRAS-G12C mutation and worse DFS in multivariable analysis (HR: 2.47). In the TCGA-LUAD stage I cohort we did not find statistically significant associations between the KRAS-G12C mutation and DFS. In the MSK-LUAD⁶⁰⁴ stage I cohort we found that KRAS-G12C mutated tumours had worse RFS when compared to KRAS-nonG12C mutated tumours in univariable analysis (HR 3.5). In the pooled stage I cohort we found that KRAS-G12C mutated tumours had worse DFS when compared to KRAS-nonG12C mutated tumours (HR 2.6), to KRAS wild-type tumours (HR 1.6) and to any other tumours (HR 1.8); in multivariable analysis, the KRAS-G12C mutation was associated with worse DFS (HR 1.61). Our results suggest that patients with resected, stage I LUAD with a KRAS-G12C mutation may have inferior survival outcomes..

ALK rearrangement is an independent predictive factor of unexpected nodal metastasis after surgery in early stage, clinical node negative lung adenocarcinoma

OBJECTIVES

Despite notable advances made in preoperative staging, unexpected nodal metastases after surgery are still significantly detected. Given the promising role of neoadjuvant targeted treatments, the definition of novel predictive factors of nodal metastases is an extremely important issue. In this study we aim to analyze the upstaging rate in patients with early stage NSCLC without evidence of nodal disease in the preoperative staging who underwent lobectomy and radical lymphadenectomy.

MATERIAL AND METHODS

Patients who underwent lobectomy and systematic lymphadenectomy for early stage LUAD without evidence of nodal disease at the preoperative staging using NGS analysis for actionable molecular targets evaluation after surgery were evaluated. Exclusion criteria included the neoadjuvant treatment, incomplete resection and no adherence to preoperative guidelines.

RESULTS

A total of 359 patients were included in the study. 172 patients were female, and the median age was 68 (61-72). The variables that showed a significant correlation with the upstaging rate at the univariate analysis were the ALK rearrangement, the number of resected lymph nodes and the diameter of the tumor. This result was confirmed in the multivariate analysis, with an OR of 8.052 (CI95% 3.123-20.763, p = 0.00001) for ALK rearrangement, 1.087 (CI95% 1.048-1.127, p = 0.00001) for the number of resected nodes and 1.817 (CI95% 1.214-2.719, p = 0.004) for cT status.

CONCLUSION

Our results showed that in a homogeneous cohort of patients with clinical node early stage LUAD the ALK rearrangement, the number of resected lymph nodes and the tumor diameter can significantly predict nodal metastasis.

Perioperative outcomes of robotic lobectomy for early-stage non-small cell lung cancer in elderly patients

Introduction

Minimally invasive surgery has become the standard for the early-stage non-small cell lung cancer (NSCLC). The appropriateness of the kind of lung resection for the elderly patients is still debated.

Methods

We retrospectively reviewed patients with older than 75 years who underwent robotic lobectomy between May 2016 to June 2022. We selected 103 patients who met the inclusion criteria of the study. The preoperative cardiorespiratory functional evaluations were collected, and the risk of postoperative complications was calculated according to the Charlson Comorbidity Index, the American College of Surgery surgical risk calculator (ACS-NSQIP), EVAD score, and American Society of Anesthesiology (ASA) score. The patients were divided in two groups according to the presence of postoperative complications.

Results

Forty-three patients were female, and 72.8% of the total population were former or active smokers. Thirty-five patients reported postoperative complications. The analysis of the two groups showed that the predicted postoperative forced expiratory volumes in the first second (FEV1) and forced vital capacity (FVC) were significantly lower in patients presenting postoperative complications (p=0.04). Moreover, the upstaging rate and the unexpected nodal metastases were higher in the postoperative complication groups.

Conclusion

Robotic-assisted lobectomy for early-stage lung cancer is a safe and feasible approach in selected elderly patients. The factors that could predict the complication rate was the predicted postoperative FEV1 and the nodal disease.

Transesophageal Endoscopic Ultrasound Fine Needle Biopsy for the Diagnosis of Mediastinal Masses: A Retrospective Real-World Analysis

Background: Endoscopic ultrasound (EUS) plays an important role in the diagnosis and staging of thoracic disease. Our report studies the diagnostic performance and clinical impact of EUS fine needle aspiration (FNA) in a homogenous cohort of patients according to the distribution of the enlarged MLNs or pulmonary masses. Methods: We retrospectively reviewed the diagnostic performance of 211 EUS-FNA in 200 consecutive patients with enlarged or PET-positive MLNs and para-mediastinal masses who were referred to our oncological center between January 2019 and May 2020. Results: The overall sensitivity of EUS-FNA was 85% with a corresponding negative predictive value (NPV) of 56% and an accuracy of 87.5%. The sensitivity and accuracy in patients with abnormal MLNs were 81.1% and 84.4%, respectively. In those with para-mediastinal masses, sensitivity and accuracy were 96.4% and 96.8%. The accuracy for both masses and lymph nodes was 100%, and in the LAG (left adrenal gland), it was 66.6%. Conclusions: Our results show that, in patients with suspected mediastinal masses, EUS-FNA is an accurate technique to evaluate all reachable mediastinal nodal stations, including station 5.

Fluorescence-guided lung nodule identification during minimally invasive lung resections

In the last few years, minimally invasive surgery has become the standard routine practice to manage lung nodules. Particularly in the case of robotic thoracic surgery, the identification of the lung nodules that do not surface on the visceral pleura could be challenging. Therefore, together with the evolution of surgical instruments to provide the best option in terms of invasiveness, lung nodule localization techniques should be improved to achieve the best outcomes in terms of safety and sensibility. In this review, we aim to overview all principal techniques used to detect the lung nodules that do not present the visceral pleura retraction. We investigate the accuracy of fluorescence guided thoracic surgery in nodule detection and the differences among the most common tracers used.

Analysis of Molecular Biomarkers in Resected Early-Stage Non-Small Cells Lung Cancer: A Narrative Review

Simple Summary

In the last few years, the treatment of advanced NSCLC has radically changed after the development of new drugs against specific molecular targets. Moreover, multiple tumour biopsies have become mandatory in order to better select the appropriate targeted therapy. Molecular analysis using NGS in the early stage of NSCLC is still relatively widespread. The recent clinical trials that use targeted therapies in neoadjuvant and adjuvant settings also require molecular characterisation for early-stage patients. Due to the widespread use of molecular analysis in patients with early-stage NSCLC, the prognostic role of molecular biomarkers needs to be fully understood. This paper aimed to review the most recent studies associating the molecular expressions of early-stage NSCLC with survival.

Abstract

Next-generation sequencing has become a cornerstone in clinical oncology practice and is recommended for the appropriate use of tailored therapies in NSCLC. While NGS has already been standardised in advanced-stage NSCLC, its use is still uncommon in the early stages. The recent approval of Osimertinib for resected EGFR-mutated NSCLC in an adjuvant setting has launched the hypothesis that other targeted therapies used in metastatic patients can also lead to improved early-stage outcomes of NSCLC. The impact of molecular biomarkers on the prognosis of patients undergoing radical surgery for NSCLC is still unclear. Notably, the heterogeneous populations included in the studies that analysed surgical patients could be the main reason for these results. In this review, we report the most important studies that analysed the impact of principal molecular biomarkers on the survival outcomes of patients who underwent radical surgery for NSCLC.

Oncological Outcomes of Robotic Lobectomy and Radical Lymphadenectomy for Early-Stage Non-Small Cell Lung Cancer

Background: While the thoracotomy approach was considered the gold standard until two decades ago, robotic surgery has increasingly strengthened its role in lung cancer treatment, improving patients’ peri-operative outcomes. In this study, we report our experience in robotic lobectomy for early-stage non-small cell lung cancer, with particular attention to oncological outcomes and nodal upstaging rate. Methods: We retrospectively reviewed patients who underwent lobectomy and radical lymphadenectomy at our Institute between 2016 and 2020. We selected 299 patients who met the inclusion criteria of the study. We analyzed the demographic features of the groups as well as their nodal upstaging rate after pathological examination. Then, we analyzed disease-free and overall survival of the entire enrolled patient population and we compared the same oncological outcomes in the upstaging and the non-upstaging group. Results: A total of 299 patients who underwent robotic lobectomy were enrolled. After surgery, 55 patients reported nodal hilar or mediastinal upstaging. The 3-year overall survival of the entire population was 82.8%. The upstaging group and the non-upstaging group were homogeneous for age, gender, smoking habits, clinical stage, tumor site, tumor histology. The non-upstaging group had better OS (p = 0.004) and DFS (p < 0.0001). Conclusion: Our results show that robotic surgery is a safe and feasible approach for the treatment of early-stage NSCLC, especially for its accuracy in mediastinal lymphadenectomy. The oncological outcomes were encouraging and consistent with previous findings.

Five years of thoracic endoscopy unit activity on lung cancer staging: how teamwork can improve the outcomes

Background

Regarding the staging of mediastinal lymph nodes before lung cancer surgery, Endobronchial Ultrasound Transbronchial Needle Aspirations (EBUS-TBNA) have proven to be highly sensitive and specific as well as safe. Endoscopic Ultrasound Fine Needle Aspirations (EUS-FNA) plays an important role in the diagnosis and staging of thoracic diseases, including lung cancer. In this study we analysed all patients underwent endoscopic procedures in our endoscopic mediastinal ultrasound unit.

Methods

Between January 2013 and February 2018, we performed a total of 929 endoscopic procedures, 432 EBUS-TBNA and 497 EUS-FNA. Biopsy was performed at the following mediastinal sites: station 7 in 642 cases, at stations 8 and 9 in 211 cases; at station 3P and 4L in 27 and 114 cases respectively; with EUS we were able to perform biopsy at station 5 in 52 cases.

Results

A total of 841 patients showed a diagnosis of cancer: non-small cell lung cancer (NSCLC) in 645 patients, SCLC in 190 patients, neuroendocrine tumour in 5 patients and one patient with mesothelioma. 88 patients were negative for cancer. In terms of sensitivity, specificity and accuracy, the association between EUS-FNAb and EBUS-TBNAb showed a better quality on diagnosis compared to single procedures. EUS-FNA and EBUS-TBNA are safe, feasible, and highly sensitive techniques.

Conclusions

An endoscopic mediastinal ultrasound unit allows to perform a higher number of endoscopic procedures and improved the sensitivity and the accuracy of the minimally invasive hilar-mediastinal staging.

Do we really need fine-needle biopsy needle for an ultrasound-guided biopsy of pancreatic adenocarcinoma? A retrospective study

OBJECTIVE

Endoscopic ultrasound (EUS)-guided FNB was not demonstrated to be better than EUS fine-needle aspiration (FNA) to obtain adequate samples for diagnosis of pancreatic tumors. We report our experience using a 22-gauge needle aspiration to obtain both cytologic and histologic samples.

PATIENTS AND METHODS

In a total of 232 patients (51% men), 22-gauge needles (Cook Medical) were used to obtain a cytological sample (between 2008 and 2016, Cohort A) and a cytologic and a histologic sample (between 2016 and 2019, Cohort B) to evaluate the usability of this needle to collect material for cytologic and histologic examination. MOSE was used.

RESULTS

Pancreatic adenocarcinoma was diagnosed in 76/113 (68%) patients in Cohort A and in 88/119 (74%) in Cohort B. Non-diagnostic sampling occurred in 30/113 (26%) patients in Cohort A and in 25/119 (21%) in Cohort B. The median number of passages was three in both cohorts. Lesions were in the head/uncinated process 57% vs. 51% and body/tail 43% vs. 49% in Cohorts A and B, respectively; the mean tumor size was 34.5 mm (SD 10.7) in Cohort A and 35.4 mm (SD 14.7) in Cohort B.

CONCLUSIONS

FNA needle (22-gauge) with adequate passes, MOSE determination and adequate processing of specimens, provided FNA and FNB specimen collection.

Not enough can be enough: feasibility of the Idylla EGFR mutation test when reuse of stained tissue slides is the only option available

AIMS

The minimally invasive procedures used in the diagnostic workup of patients with advanced non-small cell lung cancer (NSCLC) often provide poor yields of pathological material suitable for molecular analyses. Not infrequently, the DNA yield from small biopsies/cytological samples is insufficient for the assessment of genomic biomarkers that inform personalised therapies. The Idylla EGFR mutation test (IEMT) has been specifically designed to process formalin-fixed paraffin-embedded sections without requiring preliminary DNA extraction.This study aims to evaluate the diagnostic accuracy of IEMT when used to analyse archival histopathology material. More specifically, our objective was to establish whether or not different staining procedures could affect assay performance.

METHODS

Twenty NSCLC samples were selected accordingly to EGFR mutational status. To mimic archived stained material, sections were subjected to H&E staining, fluorescent in situ hybridisation analyses or immunodetection by immunohistochemistry before being processed for IEMT.

RESULTS

Parallel assessment of EGFR mutational status by IEMT on stained sections and next-generation sequencing on DNA yielded a concordant result in 50 out of 60 tests (83.3%). The discoloration of H&E of the archived sample was found to be the optimal procedure to highlight all the actionable alterations of EGFR.

CONCLUSIONS

IEMT can provide remarkable diagnostic accuracy for the assessment of EGFR mutational status also when the only source of pathological material available for molecular analyses is represented by H&E stained sections. Ad hoc supervision by a qualified molecular biologist is in any case recommended.

Mediastinal lymph node metastasis as a single expression of disease relapse in Ewing's sarcoma: multidisciplinary approach of two consecutive cases

Ewing's sarcoma of the bone is a rare, highly aggressive tumor that typically affects children and young adults. Progress in the treatment of Ewing's sarcoma has improved survival from about 10%, before the introduction of chemotherapy, to about 75% today for patients with localized tumors. On the contrary, metastatic disease still has a poor prognosis, and a multidisciplinary approach is essential to improve the outcome. Molecular techniques and new imaging modalities are affecting the diagnosis and classification of patients with Ewing's sarcoma. The most frequent sites of metastases in Ewing's sarcoma include lungs, bones and bone marrow. Lymph nodes are a rare site of metastatic spread, particularly in the mediastinum. In this report, we present two consecutive cases of patients with Ewing's Sarcoma, diagnosed, and treated at our institute. We focused particularly on the rarity of the atypical presentation of the disease and on the synergistic strategy to adopt as a model of networking in treating patients with rare diseases.

Nodal Upstaging Evaluation After Robotic-Assisted Lobectomy for Early-Stage Non-small Cell Lung Cancer Compared to Video-Assisted Thoracic Surgery and Thoracotomy: A Retrospective Single Center Analysis

Introduction: The standard surgical procedures for patients with early-stage NSCLC is lobectomy-associated radical lymphadenectomy performed by using the thoracotomy approach. In the last few years, minimally invasive techniques have increasingly strengthened their role in lung cancer treatment, especially in the early stage of the disease. Although the lobectomy technique has been accepted, controversy still surrounds lymph node dissection. In our study, we analyze the rate of upstaging early non-small cell lung cancer patients who underwent radical surgical treatment using the robotic and the VATS techniques compared to the standard thoracotomy approach.

Methods and Materials: We retrospectively reviewed patients who underwent a lobectomy and radical lymphadenectomy at our Institute between 2010 and 2019. We selected 505 patients who met the inclusion criteria of the study: 237 patients underwent robotic surgery, 158 patients had thoracotomy, and 110 patients were treated with VATS. We analyzed the demographic features between the groups as well as the nodal upstaging rate after pathological examination, the number of dissected lymph nodes and the ratio of dissected lymph nodes to metastatic lymph nodes of the three groups.

Results: The patients of the three groups were homogenous with respect to age, sex, and histology. The postoperative major morbidity rate was significantly higher in the thoracotomy group, and hospital stay was significantly longer. The percentage of the mediastinal nodal upstaging rate and the number of dissected lymph nodes was significantly higher in the robotic group compared with the VATS group. The ratio of dissected lymph nodes to metastatic lymph nodes was significantly lower compared with the VATS group and the thoracotomy group.

Discussion: The prognostic impact of the R(un) status is still highly debated. A surgical approach that allows better results in terms of resection has still not been defined. Our results show that robotic surgery is a safe and feasible approach especially regarding the accuracy of mediastinal lymphadenectomy. These findings can lead to defining a more precise pathological stage of the disease and, if necessary, to more accurate postoperative treatment.

Uniportal thoracoscopic left main bronchus resection with new lobar carina reconstruction

Isolated endobronchial tumors of the left main bronchus are quite rare. They are treated by surgical resection, preferably using lung-sparing techniques, when possible. These procedures are technically challenging and are usually performed through a standard thoracotomy.  This video tutorial shows a left main bronchus sleeve resection with distal lobar carina reconstruction, performed through a uniportal thoracoscopic approach, for a typical carcinoid tumor of the distal left main bronchus.

Induction Therapy versus Initial Surgery in Advanced Thymic Tumors: Perioperative and Oncological Outcome

Background Despite the intense debate concerning management of advanced thymic tumors, no specific oncological strategies have been yet recommended. We report our 13 years' experience to investigate this issue. Methods From 01/2001 to 12/2013, the clinical data of 28 patients treated for Masaoka stages III-IV thymic tumors were retrospectively reviewed. Eleven potentially nonresectable patients (Group A) underwent induction chemotherapy plus surgery, while immediate surgery was performed in 17 patients (Group B). The endpoint was to compare the two groups on (1) surgical resectability; (2) postoperative course; (3) disease-free survival; and (4) overall survival. Results Both groups were comparable in terms of age, gender, clinical stage, clinical tumor size, histology, and adjuvant therapy. Length of surgery was statistically longer in Group A (p = 0.015). Combined surgery and R0 resection was similarly performed in both groups (p = 0.14 and p = 0.99, respectively). The 3-year overall survival was 71.4% for Group A and 93.3% for Group B (p = 0.84). On the other hand, 3-year disease-free survival was 40.5 and 53.7% for Group A and B, respectively (p = 0.67). At multivariate analysis, gender was the strongest predictor for recurrence (hazard ratio = 5.71 [1.22; 26.67], p = 0.03). Conclusion Our results suggest that induction therapy allows obtaining acceptable clinical responses as well as resectability, survival, and recurrence rates. In selected patients with "clinically resectable" stage III-IV cancers, surgery (as first step of a multimodality therapy) could be a feasible treatment option.

Transthoracic repair of Morgagni's hernia: a 20-year experience from open to video-assisted approach

BACKGROUND

Foramen of Morgagni's hernia is an uncommon congenital diaphragmatic hernia. Repair is mostly performed through laparotomy. We prefer the transthoracic approach, which allows better and safer control during thoracic dissection, although it is considered more painful and related to greater morbidity. In recent years we introduced the transxiphoid hand-assisted videothoracoscopic approach, which combines the advantages of the thoracic route with a mini-invasive procedure facilitated by one hand inside the chest.

METHODS

A retrospective review was performed over a 20-year period (1985-2005). Twenty-two patients who had a foramen of Morgagni's hernia repaired were identified and relevant data were collected. Average age was 57 +/- 10 years and one half of the patients were asymptomatic. Chest roentgenograms, chest computerized tomography, and barium enema were used as diagnostic utilities. Posterolateral thoracotomy was performed in 17 (15 right-sided) patients, whereas in 5 (all right-sided) the defect was repaired by transxiphoid hand-assisted videothoracoscopy. Operative time, pain scored by visual analog scale, hospital stay, and cosmetic results by acceptance score were reviewed for every patient.

RESULTS

Hernial sac was present in all cases and contained only omentum (n = 13), omentum plus transverse colon (n = 7), omentum plus transverse colon and small bowel (n = 2). In 6 patients (2 videothoracoscopy) we repaired the large defects with polypropylene mesh. Videothoracoscopy achieved significant good results compared to thoracotomy in operative time (85 +/- 7.9 versus 110 +/- 11.3 min, p < 0.01), 24-h visual analog scale (3.5 +/- 1.1 versus 6.7 +/- 3.9, p < 0.01), hospital stay (2.6 +/- 0.5 versus 6.4 +/- 1.2 days, p < 0.01), and acceptance score (4.3 +/- 0.5 versus 3.1 +/- 0.8, p < 0.05). Postoperative course was always uneventful. Patients were followed for an average period of 58.6 +/- 14.7 and 109.7 +/- 43.5 months, respectively: no recurrences were found in any group.

CONCLUSIONS

We believe that the transthoracic approach is a safe and effective method for repairing Morgagni's hernia. The videothoracoscopic approach is a promising alternative and it may be facilitated by introducing a hand inside the chest.
