- Abstract
Non-intubated video-assisted thoracoscopic surgery combines a minimally invasive technique with multimodal locoregional analgesia to enhance recovery. The mainstay sedation protocol involves propofol and fentanyl. Dexmedetomidine, given its opioid-sparing effect with minimal respiratory depression, facilitates sedation in non-intubated patients. This study aimed to evaluate the efficacy of dexmedetomidine during non-intubated video-assisted thoracoscopic surgery. A total of 114 patients who underwent non-intubated video-assisted thoracoscopic surgery between June 2015 and September 2017 were retrospectively evaluated. Of these, 34 were maintained with dexmedetomidine, propofol, and fentanyl, and 80 were maintained with propofol and fentanyl. After a 1:1 propensity score-matched analysis incorporating sex, body mass index, American Society of Anesthesiologists classification, pulmonary disease and hypertension, the clinical outcomes of 34 pairs of patients were assessed. The dexmedetomidine group showed a significantly lower opioid consumption [10.3 (5.7–15.1) vs. 18.8 (10.0–31.0) mg, median (interquartile range); P = 0.001] on postoperative day 0 and a significantly shorter postoperative length of stay [3 (2–4) vs. 4 (3–5) days, median (interquartile range), P = 0.006] than the control group. During operation, the proportion of vasopressor administration was significantly higher in the dexmedetomidine group [18 (53) vs. 7 (21), patient number (%), P = 0.01]. On the other hand, the difference of the hypotension and bradycardia incidence, short-term morbidity and mortality rates between each group were nonsignificant. Adding adjuvant dexmedetomidine to propofol and fentanyl is safe and feasible for non-intubated video-assisted thoracoscopic surgery. With its opioid-sparing effect and shorter postoperative length of stay, dexmedetomidine may enhance recovery after surgery. [Display omitted] [ABSTRACT FROM AUTHOR]

- Abstract
Objective: At present, the incidence of synchronous multiple primary lung cancer (SMPLC) is increasing, and the treatment is still a challenge. This study aims to investigate the appropriate surgical procedure for treating bilateral primary lung cancer simultaneously. Methods: A retrospective analysis was conducted on clinical data from 32 patients who underwent simultaneous bilateral lung cancer surgery in our team. This data included patient characteristics, pulmonary function indicators, surgical procedures, operation duration, chest tube removal time, postoperative hospital stay, and postoperative complications. Results: Out of the 32 patients, 15 were male, and 17 were female, with an average age of 56.4 ± 8.8 years. The average maximum diameter of the main and minor tumors was 1.8 ± 1.0 cm and 1.0 ±.5 cm, respectively. All surgeries were performed thoracoscopically through intercostal approach. The procedure for the minor tumor was performed first, followed by the main tumor operation after turning over. One case was converted to thoracotomy during the main tumor operation because of bleeding. Postoperative complications occurred in one patient. No instances of respiratory insufficiency or failure were observed after the operation, and there were no perioperative deaths or readmissions within 90 days. Conclusion: Simultaneous bilateral thoracoscopic surgery is deemed a secure and feasible option for eligible patients with bilateral primary lung cancer, and it is advisable to commence the operation on the minor tumor first.

- Abstract
Postoperative pain is an important factor affecting the rapid recovery of patients undergoing thoracoscopic surgery. Effective analgesia can significantly relieve postoperative pain, reduce the use of opioids, and reduce the occurrence of postoperative complications. With the development of ultrasound technology, ultrasound-guided regional block has become an important part of postoperative analgesia in patients undergoing thoracoscopic surgery due to its advantages of high accuracy and few complications. At present, thoracic epidural analgesia, thoracic paravertebral block, serratus anterior plane block, erector spinae plane block and intercostal nerve block. etc are commonly used in thoracoscopic surgery. This article reviewed the clinical application of the various types of regional block techniques in postoperative analgesia in patients undergoing thoracoscopic surgery. [ABSTRACT FROM AUTHOR]

Abstract Background Today, the detection rate of lung nodules is increasing. Some of these nodules may become malignant. Thus, timely resection of potentially malignant nodules is essential. However, Identifying the location of nonsurface or soft-textured nodules during surgery is challenging. Various localization techniques have been developed to accurately identify lung nodules. Common methods include preoperative CT-guided percutaneous placement of hook wires and microcoils. Nonetheless, these procedures may cause complications such as pneumothorax and haemothorax. Other methods regarding localization of pulmonary nodules have their own drawbacks. We conducted a clinical study which was retrospective to identify a safe, accurate and suitable method for determining lung nodule localization. To evaluate the clinical value of CT-assisted body surface localization combined with intraoperative stereotactic anatomical localization in thoracoscopic lung nodule resection. Methods We retrospectively collected the clinical data of 120 patients who underwent lung nodule localization and resection surgery at the Department of Thoracic Surgery, First Affiliated Hospital of Bengbu Medical College, from January 2020 to January 2022. Among them, 30 patients underwent CT-assisted body surface localization combined with intraoperative stereotactic anatomical localization, 30 patients underwent only CT-assisted body surface localization, 30 patients underwent only intraoperative stereotactic anatomical localization, and 30 patients underwent CT-guided percutaneous microcoil localization. The success rates, complication rates, and localization times of the four lung nodule localization methods were statistically analysed. Results The success rates of CT-assisted body surface localization combined with intraoperative stereotactic anatomical localization and CT-guided percutaneous microcoil localization were both 96.7%, which were significantly higher than the 70.0% success rate in the CT-assisted body surface localization group (P

This study aimed to evaluate the two administration routes of dexmedetomidine on acute pain and chronic neuropathic pain (NeuP) prevention compared with no dexmedetomidine.Methods: A total of 216 patients were randomized to receive TPVB using 0.4% ropivacaine alone (R Group), with perineural dexmedetomidine 0.5 μg·kg− 1 (RD0.5 Group) or 1.0 μg·kg− 1 (RD1.0 Group), or intravenous (IV) dexmedetomidine 0.5 μg·kg− 1·h− 1 (RDiv Group). The primary outcome was the incidence of chronic NeuP, defined as a Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) pain score > 12 points at 3-month after surgery.Results: (1) For the primary outcome, RD0.5 Group and RD1.0 Group demonstrated a decreased incidence of chronic NeuP at 3-month after surgery; (2) Compared with R Group, RDiv Group, RD0.5 Group, and RD1.0 Group can reduce VAS scores at rest and movement and Prince-Henry Pain scores at 12 and 24-h after surgery, the consumption of oral morphine equivalent (OME) and improve QOD-15 at POD1; (3) Compared with RDiv Group, RD0.5 Group and RD1.0 Group can reduce VAS scores at rest and movement and Prince-Henry Pain scores at 12 and 24-h after surgery, the consumption of postoperative OME and improve QOD-15 at POD1; (4) Compared with RD0.5 Group, RD1.0 Group effectively reduced VAS scores at rest at 12 and 24-h after surgery, VAS scores in movement and Prince-Henry Pain scores at 12-h after surgery. However, RD1.0 Group showed an increased incidence of drowsiness.Conclusion: Perineural or IV dexmedetomidine are similarly effective in reducing acute pain, but only perineural dexmedetomidine reduced chronic NeuP. Moreover, considering postoperative complications such as drowsiness, perineural dexmedetomidine (0.5 μg·kg− 1) may be a more appropriate choice.Clinical Trial Registration: Chinese Clinical Trial Registry (ChiCTR2200058982).Keywords: dexmedetomidine, thoracic paravertebral nerve block, neuropathic pain, thoracoscopic surgery

The complication rate in the combined group was 0%, which was significantly lower than the 60% in the microcoil localization group (P < 0.05). The localization time for the combined group was 17.73 ± 2.52 min, which was significantly less than that (27.27 ± 7.61 min) for the microcoil localization group (P < 0.05). Conclusions: CT-assisted body surface localization combined with intraoperative stereotactic anatomical localization is a safe, painless, accurate, and reliable method for lung nodule localization.

Background: Thromboembolic occlusion of the superior mesenteric artery (SMA) is a grave complication in individuals diagnosed with atrial fibrillation (AF). This condition often necessitates extensive bowel resection, culminating in short bowel syndrome, which presents challenges for anticoagulant administration and/or antiarrhythmic therapy. Case presentation: Presented here are findings of two patients, aged 78 and 72 years, respectively, who underwent comprehensive thoracoscopic AF surgery subsequent to extensive small bowel resection following SMA embolization. In each, onset of AF precipitated an embolic event, while the concurrent presence of short bowel syndrome complicated anticoagulation management. Total thoracoscopic AF surgery, comprised stapler-closure of the left atrial appendage (LAA) and bilateral epicardial clamp-isolation of the pulmonary veins, an operative modality aimed at addressing AF rhythm control and mitigating embolic events such as cerebral infarction, led to favorable outcomes in both cases. Additionally, computed tomography (CT) conducted one month post-surgery revealed the absence of residual tissue in the LAA, with the left atrium demonstrating a well-rounded, spherical shape. At the time of writing, the patients have remained asymptomatic following surgery regarding thromboembolic and arrhythmic manifestations for 29 and 10 months, respectively, notwithstanding the absence of anticoagulant or antiarrhythmic pharmacotherapy. Additionally, electrocardiographic surveillance has revealed persistent sinus rhythm. Conclusions: The present findings underscore the feasibility and efficacy of a total thoracoscopic AF surgery procedure for patients presented with short bowel syndrome complicating SMA embolization, thus warranting consideration for its broader clinical application.

Purpose: The optimal surgical approach for recurrent congenital diaphragmatic hernia (CDH) remains controversial. We compared the surgical outcomes of a thoracoscopic approach versus an open abdominal approach for recurrent CDH after initial abdominal open repair. Method: The subjects of this comparative study were patients who underwent open abdominal or thoracoscopic surgery for recurrent CDH following an initial open abdominal repair. Results: Among 166 patients with Bochdalek-type CDH, 15 underwent reoperation for recurrent CDH following an open abdominal repair. Seven patients underwent open abdominal surgery (group O) and eight underwent thoracoscopic surgery (group T). The operative duration was similar for the two groups, with less blood loss (17.2 ml/kg vs. 1 ml/kg, P = 0.001) and fewer intraoperative complications in the T group (n = 6 vs. n = 0 cases, P = 0.001). There was no significant difference in the number of postoperative complications (n = 1 vs. n = 1, P = 1.0) or in the number of patients with a second CDH recurrence (n = 2 vs. n = 1, P = 0.569) between the two groups. Conclusion: Thoracoscopic surgery is preferable to the open surgical approach for recurrent CDH following an initial abdominal open repair. [ABSTRACT FROM AUTHOR]

Purpose: To develop deep learning models using thoracoscopic images to identify visceral pleural invasion (VPI) in patients with clinical stage I lung adenocarcinoma, and to verify if these models can be applied clinically. Methods: Two deep learning models, one based on a convolutional neural network (CNN) and the other based on a vision transformer (ViT), were applied and trained via 463 images (VPI negative: 269 images, VPI positive: 194 images) captured from surgical videos of 81 patients. Model performances were validated via an independent test dataset containing 46 images (VPI negative: 28 images, VPI positive: 18 images) from 46 test patients. Results: The areas under the receiver operating characteristic curves of the CNN-based and ViT-based models were 0.77 and 0.84 (p = 0.304), respectively. The accuracy, sensitivity, specificity, and positive and negative predictive values were 73.91, 83.33, 67.86, 62.50, and 86.36% for the CNN-based model and 78.26, 77.78, 78.57, 70.00, and 84.62% for the ViT-based model, respectively. These models' diagnostic abilities were comparable to those of board-certified thoracic surgeons and tended to be superior to those of non-board-certified thoracic surgeons. Conclusion: The deep learning model systems can be utilized in clinical applications via data expansion. [ABSTRACT FROM AUTHOR]

- Abstract
Objectives: Spontaneous pneumothorax in young patients has a high recurrence rate, even after surgical treatment, and bulla neogenesis around stapled lesions has been reported as a cause of postoperative recurrence. We investigate the clinical safety and long-term outcome of non-stapling thoracoscopic surgery for spontaneous pneumothorax in young patients. Methods: Twenty-seven non-stapling thoracoscopic surgeries for pneumothorax in 24 patients younger than 25 years were retrospectively reviewed. The non-stapling surgical techniques used to treat bullae included thoracoscopic suture plication, soft-coagulation, covering, and ligation. Long-term follow-up was conducted by telephone or by a mailed questionnaire. Results: In 22 (81.5%) operations, suture plication, soft-coagulation, and covering procedures were used in combination. The median number of bullae treated in one operation was 2 (range, 0–6). The median operative time was 97 min, and the median postoperative drainage and postoperative hospital stay periods were 1 and 3 days, respectively. No complications of grade 2 or higher were observed. Patients were followed for at least 30 (median, 37) months. The postoperative recurrence rate was 3.7%, with one case of recurrence due to bulla neogenesis at a distant site. Conclusion: Non-stapling thoracoscopic surgery with covering procedure for pneumothorax in young patients might reduce postoperative recurrence. [ABSTRACT FROM AUTHOR]

With the introduction of multi-detector computed tomography (CT), the number of incidentally detected small lung nodules has dramatically increased. Determination of lung nodule malignancy is crucial, and an early diagnosis of these indeterminate lesions can lead to subsequent potentially curative treatment. However, there are some limitations to excising these nodules with sublobar resection in a minimally invasive thoracoscopic setting. Under thoracoscopy, although stapler-based wedge resection seems to be the preferred technique, particularly in patients whose lesions are located far from the edge of the lobe, the stapler can unexpectedly sacrifice normal pulmonary parenchyma. To overcome this issue, we have developed a wireless excision precision technique using cone-beam CT-guided electromagnetic navigation bronchoscopy in a minimally invasive thoracoscopic setting. Our technique is implemented in a hybrid operating room, and small tumors can be removed using a radiofrequency identification microchip without intraoperative fluoroscopy and do not require lung palpation under thoracoscopy.

We previously demonstrated the usefulness of combining stitching with covering to seal alveolar air leaks in an animal model. This study aimed to clarify the effectiveness and feasibility of this sealing method in the clinical setting. Data of 493 patients who underwent thoracoscopic anatomical resection between 2013 and 2020 for lung cancer were retrospectively reviewed. Prolonged air leak was defined as chest drain placement lasting 5 d or longer due to air leak. Until July 2017 (early study period), we covered air leaks using mesh. However, for sealing (late study period), we additionally stitched leaks with pledget in patients at high risk of prolonged air leak. The pneumostasis procedure, intraoperative confirmation test of pneumostasis, and chest tube management were uniform during both periods. The incidence of prolonged air leak was significantly lower in the late than in the early period (3.6% versus 12.5%), whereas pulmonary emphysema was more severe in the late period compared to the early period. Intraoperative failure of sealing air leaks was significantly reduced in the late period than in the early period. In both univariate and propensity score matching analysis, the study period was a significant predictor of prolonged air leak. The combination of stitching and covering with mesh may contribute to reducing prolonged air leak incidence in patients undergoing thoracoscopic anatomical lung resection for lung cancer.

We conducted this study aimed to evaluate the analgesic effect of dexmedetomidine in thoracoscopic surgery on postoperative wound pain, and to provide a reference for clinical use of the drug. We searched PubMed, Embase, Cochrane Library, Web of Science, Wanfang, Chinese Biomedical Literature Database and China National Knowledge Infrastructure databases, and supplemented with manual searching. We searched from database inception to October 2023, to collect the randomised controlled trials (RCTs) on dexmedetomidine application in thoracoscopic surgery. Two researchers screened all the literature according to the inclusion and exclusion criteria and the literature included in the study was evaluated for quality, extracted information and required data. Stata 17.0 software was employed for data analysis and the outcomes were 2 6, 12, 24 and 48 h postoperative wound visual analog scores (VAS). Twenty‐four RCTs totalling 2246 patients undergoing thoracoscopic surgery were finally included. The analysis revealed dexmedetomidine applied to thoracoscopic surgery significantly reduced the postoperative wound VAS scores at 2 h (SMD: −0.96, 95% CI: −1.57 to −0.36, p = 0.002), 6 h (SMD: −0.98, 95% CI: −1.27 to −0.69, p < 0.001), 12 h (SMD: −1.19, 95% CI: −1.44 to −0.94, p < 0.001), 24 h (SMD: −0.91, 95% CI: −1.16 to −0.66, p < 0.001) and 48 h (SMD: −0.75, 95% CI: −1.02 to −0.48, p < 0.001). Our results suggest dexmedetomidine applied to thoracoscopic surgery can significantly reduce postoperative wound pain, which is worthy of clinical application. [ABSTRACT FROM AUTHOR]

Abstract Lymphoid follicular hyperplasia (LFH) is a benign lymphoproliferative disease. Although it can occur within the thoracic cavity, LFH originating from the chest wall has not been reported. A 79‐year‐old woman was incidentally found to have a well‐defined mass on the left posterior chest wall during a preoperative examination for aortic valve replacement. The mass had slowly grown over 6 years. Thoracoscopic surgical resection was performed without complications. Pathological examination ruled out lymphoproliferative diseases, such as Castleman disease or malignant lymphoma, and a diagnosis of LFH was made. Although LFH generally has a good prognosis, surgical resection is recommended for diagnostic and therapeutic purposes owing to the possibility of malignancy masquerading as a reactive lesion. This is the first report of an LFH arising from the chest wall with imaging findings similar to other benign tumours. Its potential as a differential diagnosis for tumours with similar imaging findings is highlighted.

Lymphoid follicular hyperplasia (LFH) is a benign lymphoproliferative disease. Although it can occur within the thoracic cavity, LFH originating from the chest wall has not been reported. A 79‐year‐old woman was incidentally found to have a well‐defined mass on the left posterior chest wall during a preoperative examination for aortic valve replacement. The mass had slowly grown over 6 years. Thoracoscopic surgical resection was performed without complications. Pathological examination ruled out lymphoproliferative diseases, such as Castleman disease or malignant lymphoma, and a diagnosis of LFH was made. Although LFH generally has a good prognosis, surgical resection is recommended for diagnostic and therapeutic purposes owing to the possibility of malignancy masquerading as a reactive lesion. This is the first report of an LFH arising from the chest wall with imaging findings similar to other benign tumours. Its potential as a differential diagnosis for tumours with similar imaging findings is highlighted. [ABSTRACT FROM AUTHOR]

BackgroundDepressive symptoms are common among patients with lung cancer. We aimed to assess the effects of esketamine on postoperative depressive symptoms after thoracoscopic lung cancer surgery.MethodsIn this randomized, double-blind, placebo-controlled trial, 156 patients undergoing thoracoscopic lung cancer surgery were randomly allocated in a 1:1 ratio to receive intravenous esketamine (intraoperatively and in patient-controlled analgesia until 48 h postoperatively) or normal saline placebo. The primary outcome was the proportion of patients with depressive symptoms at 1 month postoperatively, assessed using the Beck Depression Inventory-II (BDI-II). Secondary outcomes included depressive symptoms at 48 h postoperatively, hospital discharge and 3 months postoperatively, BDI-II scores, anxious symptoms, Beck Anxiety Inventory scores, Quality of Recovery-15 (QoR-15) scores, and 1- and 3-month mortality.Main resultsA total of 151 patients (75 in the esketamine group and 76 in the normal saline group) completed the 1-month follow-up. The esketamine group had a significantly lower incidence of depressive symptoms at 1 month compared to the normal saline group (1.3% vs. 11.8%; risk difference = -10.5, 95%CI = -19.6% to -0.49%; p = 0.018). After excluding patients without lung cancer diagnosis, the incidence of depressive symptoms was also lower in the esketamine group (1.4% vs. 12.2%; risk difference = -10.8, 95%CI = -20.2% to -0.52%; p = 0.018). The secondary outcomes were similar between groups, except that the esketamine group had higher QoR-15 scores at 1 month postoperatively (median difference = 2; 95%CI = 0 to 5; p = 0.048). The independent risk factors for depressive symptoms were hypertension (odds ratio = 6.75, 95%CI = 1.13 to 40.31; p = 0.036) and preoperative anxious symptoms (odds ratio = 23.83, 95%CI = 3.41 to 166.33; p = 0.001).ConclusionPerioperative administration of esketamine reduced the incidence of depressive symptoms at 1 month after thoracoscopic lung cancer surgery. History of hypertension and preoperative anxious symptoms were independent risk factors for depressive symptoms.Clinical trial registration: Chinese Clinical Trial Registry http://www.chictr.org.cn, Identifier (ChiCTR2100046194).

Abstract Objective Postoperative fasting following thoracoscopic surgery can cause intense thirst and oral discomfort. However, there is currently no research on ultraearly oral hydration (UEOH) in middle-aged or elderly patients after thoracoscopic surgery. The aim of this study was to investigate the effectiveness and safety of UEOH for improving oral discomfort after thoracoscopic surgery. Methods This single-center prospective double-blind randomized controlled trial was conducted from April 2022 to November 2023. A total of 64 middle-aged and elderly patients who underwent the first thoracoscopic surgery on the day were enrolled at our institution. Postoperatively, in the Postanesthesia Care Unit (PACU), patients were randomly assigned at a 1:1 ratio to either the UEOH group or the standard care (SC) group. The primary outcome was the patient’s thirst score at 6 h after surgery. Secondary outcomes included the incidence of postoperative oral discomfort; pain scores; the occurrence of adverse reactions such as nausea, vomiting, regurgitation and aspiration; anxiety scores on the first postoperative day; the time to first flatus; and recovery satisfaction scores. Results The demographic and surgical characteristics were similar between the two groups. Patients in the UEOH group had lower thirst scores 6 h after surgery than did those in the SC group(16.1 ± 6.70 vs. 78.4 ± 8.42, P 0.05). Conclusion For middle-aged and elderly patients undergoing thoracoscopic surgery, the use of a modified UEOH protocol postoperatively can improve thirst and promote gastrointestinal recovery without increasing complications. Trial registration This single-center, prospective, RCT has completed the registration of the Chinese Clinical Trial Center at 07/12/2023 with the registration number ChiCTR2300078425.

Abstract Background This study aimed to observe the effect of opioid-free anaesthesia (OFA) on intraoperative haemodynamic,postoperative analgesia and postoperative nausea and vomiting (PONV) in thoracoscopic surgery in order to provide more evidence for evaluating the safety and effectiveness of OFA technology. Methods This was a single-centre retrospective observational study.Adult patients who underwent thoracoscopic surgery with the preoperative thoracic paravertebral block between January 2017 and June 2020 were included.A cohort of 101 thoracoscopic surgery patients who received the OFA technique were matched with 101 thoracoscopic surgery patients who received standard opioid-containing anaesthesia(SOA). Heart rate (HR) and mean arterial blood pressure (MAP) were measured before anaesthesia induction, immediately after endotracheal intubation, at the beginning of surgery, and 10, 20, and 30 min after surgery began.The total amount of intraoperative infusion, frequency of vasoactive drugs use, morphine ingested via the patient-controlled intravenous analgesia (PCIA) 24 h post-surgery,visual analogue scale (VAS) scores at rest and activity on the first day post-surgery, and frequency of nausea and vomiting within 24 h post-surgery were analysed. Results There was no significant difference in intraoperative HR between the two groups (F = 0.889, P = 0.347); however, there was significant difference in intraoperative MAP (F = 16.709, P

Bijia Song, Xiuliang Li, Jiguang Yang, Wenjing Li, Lei Wan Department of Anesthesiology, Beijing Friendship Hospital, Capital Medical University, Beijing, 100050, People’s Republic of ChinaCorrespondence: Lei Wan, Email wanleimz@sina.comIntroduction: Seeking effective multimodal analgesia and anesthetic regimen is the basis for the success of ERAS. Opioid-free anesthesia (OFA) is a multimodal anesthesia associating hypnotics, N-methyl-D-aspartate (NMDA) antagonists, local anesthetics, anti-inflammatory drugs and α-2 agonists. Although previous studies have confirmed that OFA is safe and feasible for VATS surgery, there is great heterogeneity in how to select and combine anti-harm drugs to replace opioids. We hypothesized that the reduced opioid use during and after surgery allowed by OFA compared with standard of care will be associated with a reduction of postoperative opioid-related adverse events and an improvement in the quality of rehabilitation of patients after partial VATS lung resection.Methods/Analysis: The TEDOFA Study is a prospective double-blind, randomized, controlled clinical trial with a concealed allocation of patients scheduled to undergo elective partial VATS pneumonectomy 1:1 to receive either a standard anesthesia protocol or an OFA. A total of 146 patients were recruited in the study. Primary endpoint was the 15-item recovery quality scale (QoR-15) at 24 hours after surgery.Ethics and Dissemination: This trial has been approved by the Institutional Review Board of Beijing Friendship Hospital of China Capital University. The TEDOFA trial study protocol was approved on 27 February 2023.

The primary outcome was the incidence of POD within three days after surgery. Secondary outcomes included the Confusion Assessment Method (CAM) score, intraoperative indicators related to mean arterial pressure (MAP), and cerebral tissue oxygen saturation (SctO2). Moreover, MAP- and SctO2-related indicators associated with POD were analyzed.Results: The incidence of POD was 7.1% and 16.7%, respectively, in the ciprofol group and the propofol group (risk ratio [RR], 0.37; 95% confidence interval [CI], 0.07 to 2.03; risk difference [RD], − 9.6%; 95% CI, − 23.3% to 4.1%; p = 0.178). Compared with those in the propofol group, patients in the ciprofol group had lower CAM scores three days after surgery (13 (12, 15) vs 15 (14, 17); 12 (11, 13) vs 14 (13, 16); 12 (11, 12) vs 13 (12, 14), p< 0.05). Besides, patients in the ciprofol group exhibited higher mean and minimum MAP (88.63 ± 6.7 vs 85 ± 8.3; 69.81 ± 9.59 vs 64.9 ± 9.43, p< 0.05) and SctO2 (77.26 ± 3.96 vs 75.3 ± 4.49, 71.69 ± 4.51 vs 68.77 ± 6.46, p< 0.05) and percentage of time for blood pressure stabilization (0.6 ± 0.14 vs 0.45 ± 0.14, p< 0.05) than those in the propofol group. Furthermore, MAP and SctO2-related indicators were validated to correlate with POD.Conclusion: Anesthesia with ciprofol did not increase the incidence of POD compared with propofol. The results demonstrated that ciprofol could improve intraoperative MAP and SctO2 levels and diminish postoperative CAM scores.Keywords: ciprofol, postoperative delirium, thoracoscopic surgery, cerebral tissue oxygen saturation

Introduction: Over the years, congenital lung malformations (CLM) management remains a controversial topic in pediatric thoracic surgery. The Italian Society of Pediatric Surgery performed a national survey to study the current management variability among centers, trying to define national guidelines and a standardized approach of children with congenital lung malformations. Methods: Following a National Society approval, an electronic survey including 35 items on post-natal management was designed, focusing on surgical, anesthesiology, radiology and pneumology aspects. The survey was conducted contacting all pediatric surgical units performing thoracic surgery. Results: 39 pediatric surgery units (97.5%) participated in the study. 13 centers (33.3%) were classified as high-volume (Group A), while 26 centers (66.7%) were low volume (Group B). Variances in diagnostic imaging protocols were observed, with Group A performing fewer CT scans compared to Group B (p = 0.012). Surgical indications favored operative approaches for asymptomatic CLM and pulmonary sequestrations in both groups, while a wait-and-see approach was common for congenital lobar emphysema. Surgical timing for asymptomatic CLM differed significantly, with most high-volume centers operating on patients younger than 12 months (p = 0.02). Thoracoscopy was the preferred approach for asymptomatic CLM in most of centers, while postoperative long-term follow-up was not performed in most of the centers. Conclusion: Thoracoscopic approach seems uniform in asymptomatic CLM patients and variable in symptomatic children. Lack of uniformity in surgical timing and preoperative imaging assessment has been identified as key areas to establish a common national pattern of care for CLM. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: Postoperative nausea and vomiting (PONV) is a prevalent postsurgical complication. The objective of our study was to compare the effect of different doses of dexmedetomidine on PONV in female patients undergoing radical thoracoscopic lung cancer resection. Methods: A total of 164 female patients undergoing elective thoracoscopic radical lung cancer surgery were enrolled and assigned to one of four groups. Patients received 0.2 µg/kg/h, 0.4 µg/kg/h, 0.8 µg/kg/h dexmedetomidine and normal saline in the Dex1, Dex2, Dex3 and Control groups, respectively. The primary outcome was the incidence of PONV during 48 h postoperatively. The second outcomes included the incidence of PONV and postoperative vomiting (POV) at four time points postoperatively (T1: PACU retention period; T2: PACU discharge to postoperative 12 h; T3: postoperative 12 h-postoperative 24 h; T4: postoperative 24 h-postoperative 48 h), the area under the curve of PONV grade (PONVAUC), PONV grade, POV grade and other postoperative recovery indicators. Results: The incidence of PONV differed among the four groups. The Dex2 group (29.27%) was lower than that in the Dex1 group (61.90%) and Control group (72.50%). The incidence of PONV at T2 in the Dex1 group (11.90%) and Dex2 group (9.76%) was lower than that in the Control group (42.50%). The incidence of PONV at T3 in the Dex2 group (29.27%) was lower than that in the Dex1 group (61.90%) and Control group (62.50%). The PONVAUC was lower in the Dex2 group than in the Control group. The incidence of POV at T3 in the Dex2 and Dex3 groups was lower than that in the Control group. The consumption of remifentanil, norepinephrine, PACU dwell time, VAS scores, postoperative PCA press frequency, and the time for the first postoperative oral intake were different among the four groups. The regression model shows that the Dex2 group is a protective factor for PONV. Conclusion: Dexmedetomidine can reduce the incidence of PONV and accelerate postoperative recovery in female patients undergoing radical thoracoscopic lung cancer resection. Compared with the other two dosages, 0.4 µg/kg/h dexmedetomidine is preferable. [ABSTRACT FROM AUTHOR]

Open in new tab Download slide OBJECTIVES Virtual training simulators have been introduced in several surgical disciplines to improve residents' abilities. Through the use of the LapSim® virtual training simulator (Surgical Science, Göteborg, Sweden), this study aims to plan an effective learning path in minimally invasive thoracic and general surgery. METHODS All thoracic and general surgery trainees in their 1st and 2nd year of residency at the University of Insubria were enrolled and randomized into 2 groups: residents undergoing an intensive twice-a-week virtual training programme (group A: n = 8) and those undergoing a once-weekly non-intensive virtual training programme (group B: n = 9). The virtual training programme was divided into 4 modules, each of 12 weeks. In the 1st module, trainees repeated grasping, cutting, clip application, lifting and grasping, and fine dissection exercises during each training session. Seal-and-cut exercise was performed as the initial and final test. Data on surgical manoeuvres (time and on mistakes) were collected; intra- and inter-group comparisons were planned. RESULTS No significant differences were observed between groups A and B at the 1st session, confirming that the 2 groups had similar skills at the beginning. After 12 weeks, both groups showed improvements, but comparing data between initial and final test, only Group A registered a significant reduction in total time (P -value = 0.0015), left (P -value = 0.0017) and right (P -value = 0.0186) instrument path lengths, and in left (P -value = 0.0010) and right (P -value = 0.0073) instrument angular path lengths, demonstrating that group A acquired greater precision in surgical manoeuvres. CONCLUSIONS Virtual simulator training programme performed at least twice a week was effective for implementing basic surgical skills required for the trainee's professional growth. Additional virtual training modules focused on more complex exercises are planned to confirm these preliminary results. [ABSTRACT FROM AUTHOR]

Marcon, Salvatore, Anania, Gabriele, and Tamburini, Nicola
- Abstract
Introduction: Epiphrenic diverticulum is a rare disease caused by mucosa and submucosa herniation through the muscular layers of the esophageal wall. This study presents a case of a patient with a symptomatic epiphrenic diverticulum treated with surgery under endoscopic assistance. A review of the literature on this unusual condition was conducted, focusing on the pathogenesis, presentation, and surgical challenges. Methods: A 75-year-old woman who underwent an esophagogastroduodenoscopy (EGD) after experiencing worsening dysphagia for food and liquids. The EGD revealed a large epiphrenic diverticulum 36 cm from the upper incisor teeth. The presence of a diverticulum was verified by barium swallow, which revealed a 6 cm diameter epiphrenic diverticulum on the right side of the esophagus. Results: Patient underwent laparoscopic diverticulectomy associated with Heller's myotomy and anterior partial fundoplication. A gastroscope was placed intraoperatively to calibrate the esophagus to prevent stenosis during diverticulectomy, and it was also used to check the integrity of the esophageal wall. The patient tolerated clear liquids on postoperative day 2. Postoperative course was complicated by right pleural effusion and fever managed with antibiotics and pleural drainage. Conclusion: Epiphrenic diverticulectomy in conjunction with management of the underlying motor dysfunction and avoidance of gastroesophageal reflux disease is an effective procedure. Laparoscopy is considered the approach of choice for the majority of patients. Endoscopic assistance during surgery can help the identification of the diverticulum and verify the integrity of the staple line. [ABSTRACT FROM AUTHOR]

Introduction: Treatments for multiple ground-glass opacities (GGOs) for which the detection rate is increasing are still controversial. Next-generation sequencing (NGS) may provide additional key evidence for differential diagnosis or optimal therapeutic schedules. Case presentation: We first reported a rare case in which more than 100 bilateral pulmonary GGOs (91.7% of the GGOs were pure GGOs) were diagnosed as both multiple primary lung cancer and intrapulmonary metastasis. We performed NGS with an 808-gene panel to assess both somatic and germline alterations in tissues and plasma. The patient (male) underwent three successive surgeries and received osimertinib adjuvant therapy due to signs of metastasis and multiple EGFR-mutated tumors. The patient had multiple pure GGOs, and eight tumors of four pathological subtypes were evaluated for the clonal relationship. Metastasis, including pure GGOs and atypical adenomatous hyperplasia, was found between two pairs of tumors. Circulating tumor DNA (ctDNA) monitoring of disease status may impact clinical decision-making. Conclusions: Surgery combined with targeted therapies remains a reasonable alternative strategy for treating patients with multifocal GGOs, and NGS is valuable for facilitating diagnostic workup and adjuvant therapy with targeted drugs through tissue and disease monitoring via ctDNA.

- Abstract
Anterior mediastinal procedures are increasingly being performed using robot-assisted thoracic surgery (RATS) or video-assisted thoracoscopic surgery (VATS). While both approaches have shown superior outcomes compared to open surgery, their comparative benefits are not as distinct. The aim of this retrospective study was to bridge this knowledge gap using a multicenter dataset. Patients who underwent elective minimally invasive surgery for anterior mediastinal disease between 2015 and 2022 were deemed eligible. The study participants were grouped based on whether a robot was used or not, and perioperative outcomes were compared. To mitigate selection bias, inverse probability of treatment weighting (ITPW) was applied using the propensity score. The final analysis included 312 patients (RATS = 120; VATS = 192). Following the application of IPTW, RATS was found to be associated with a longer operating time (215.3 versus 139.31 min, P < 0.001), fewer days with a chest tube (1.96 versus 2.61 days, P = 0.047), and a shorter hospital stay (3.03 versus 3.91 days, P = 0.041) compared to VATS. Subgroup analyses indicated that the benefit of RATS in reducing the length of hospital stay was particularly pronounced in patients with tumors larger than 6 cm (mean difference [MD] = – 2.28 days, P = 0.033), those diagnosed with myasthenia gravis (MD = – 3.84 days, P = 0.002), and those who underwent a trans-subxiphoid surgical approach (MD = – 0.81 days, P = 0.04). Both VATS and RATS are safe and effective approaches for treating anterior mediastinal disease. However, RATS holds distinct advantages over VATS including shorter hospital stays and reduced chest tube drainage periods. [ABSTRACT FROM AUTHOR]

Background: Postoperative gastrointestinal dysfunction (PGD) is one of the most common complications among patients who have undergone thoracic surgery. Acupuncture has long been used in traditional Chinese medicine to treat gastrointestinal diseases and has shown benefit as an alternative therapy for the management of digestive ailments. This study aimed to explore the therapeutic effectiveness of acupuncture as a means to aid postoperative recovery of gastrointestinal function in patients undergoing thoracoscopic surgery. Methods: In total, 112 patients aged 18–70 years undergoing thoracoscopic surgery between 15 June 2022 and 30 August 2022 were randomized into two groups. Patients in the acupuncture group (AG) first received acupuncture treatment 4 h after surgery, and treatment was repeated at 24 and 48 h. Patients in the control group (CG) did not receive any acupuncture treatment. Both groups received the same anesthetic protocol. Ultrasound-guided thoracic paravertebral block (TPVB) was performed in the paravertebral spaces between T4 and T5 with administration of 20 mL of 0.33% ropivacaine. All patients received patient-controlled intravenous analgesia (PCIA) after surgery. Results: Median time to first flatus [interquartile range] in the AG was significantly less than in the CG (23.25 [18.13, 29.75] vs 30.75 [24.13, 45.38] h, p < 0.001). Time to first fluid intake after surgery was significantly less in the AG, as compared with the CG (4 [3, 7] vs 6.5 [4.13, 10.75] h, p = 0.003). Static pain, measured by visual analog scale (VAS) score, was significantly different on the third day after surgery (p = 0.018). Dynamic pain VAS scores were lower in the AG versus CG on the first three postoperative days (p = 0.014, 0.003 and 0.041, respectively). Conclusion: Addition of acupuncture appeared to improve recovery of postoperative gastrointestinal function and alleviate posteoperative pain in patients undergoing thoracoscopic surgery. Acupuncture may represent a feasible strategy for the prevention of PGD occurrence. Trial registration number: ChiCTR2200060888 (Chinese Clinical Trial Registry) [ABSTRACT FROM AUTHOR]

Thoracoscopic surgical biopsy has shown excellent histological characterization of undetermined interstitial lung diseases, although the morbidity rates reported are not negligible. In delicate patients, interstitial lung disease and restrictive ventilatory impairment morbidity are thought to be due at least in part to tracheal intubation with single-lung mechanical ventilation; therefore, spontaneous ventilation thoracoscopic lung biopsy (SVTLB) has been proposed as a potentially less invasive surgical option. This systematic review summarizes the results of SVTLB, focusing on diagnostic yield and operative morbidity. A systematic search for original studies regarding SVTLB published between 2010 to 2023 was performed. In addition, articles comparing SVTLB to mechanical ventilation thoracoscopic lung biopsy (MVTLB) were selected for a meta-analysis. Overall, 13 studies (two before 2017 and eleven between 2018 and 2023) entailing 675 patients were included. Diagnostic yield ranged from 84.6% to 100%. There were 64 (9.5%) complications, most of which were minor. There was no 30-day operative mortality. When comparing SVTLB to MVTLB, the former group showed a significantly lower risk of complications (p < 0.001), whereas no differences were found in diagnostic accuracy. The results of this review suggest that SVTLB is being increasingly adopted worldwide and has proven to be a safe procedure with excellent diagnostic accuracy. [ABSTRACT FROM AUTHOR]

Introduction: Assistant surgeons usually clean the surgical field with a suction cannula in robotic‐assisted surgery. This manipulation requires skill and experience to avoid interfering with the operation of the console surgeon. Recently, we created a new suction device that a console surgeon can manipulate with the robotic arms. Materials and Surgical Technique: A small metal suction tip with as a lumen and small side pores for suction and can be connected to a silicone tube connected to wall suction. The tip of the silicone tube can be grasped with robotic forceps and used for organ retraction as well as suction. The suction device has been used in eight lung lobectomy cases and four lung segmentectomy cases to date. There were no major difficulties related to the new suction device except for metal tip disconnection and blood clots clogging. Discussion: Our newly developed surgeon‐controlled suction device is inexpensive, easy to handle, and useful for suction, blunt dissection, and organ retraction in robotic‐assisted thoracoscopic surgery, especially when performing lymph node dissection.

AbstractObjective Delayed extubation was commonly associated with increased adverse outcomes. This study aimed to explore the incidence and predictors and to construct a nomogram for delayed extubation after thoracoscopic lung cancer surgery.Methods We reviewed medical records of 8716 consecutive patients undergoing this surgical treatment from January 2016 to December 2017. Using potential predictors to develop a nomogram and using a bootstrap-resampling approach to conduct internal validation. For external validation, we additionally pooled 3676 consecutive patients who underwent this procedure between January 2018 and June 2018. Extubation performed outside the operating room was defined as delayed extubation.Results The rate of delayed extubation was 1.60%. Multivariate analysis identified age, BMI, FEV1/FVC, lymph nodes calcification, thoracic paravertebral blockade (TPVB) usage, intraoperative transfusion, operative time and operation later than 6 p.m. as independent predictors for delayed extubation. Using these eight candidates to develop a nomogram, with a concordance statistic (C-statistic) value of 0.798 and good calibration. After internal validation, similarly good calibration and discrimination (C-statistic, 0.789; 95%CI, 0.748 to 0.830) were observed. The decision curve analysis (DCA) indicated the positive net benefit with the threshold risk range of 0 to 30%. Goodness-of-fit test and discrimination in the external validation were 0.113 and 0.785, respectively.Conclusion The proposed nomogram can reliably identify patients at high risk for the decision to delayed extubation after thoracoscopic lung cancer surgery. Optimizing four modifiable factors including BMI, FEV1/FVC, TPVB usage, and operation later than 6 p.m. may reduce the risk of delayed extubation.Key Messages:This study identified eight independent predictors for delayed extubation, among which lymph node calcification and anaesthesia type were not commonly reported.Using these eight candidates to develop a nomogram, we could reliably identify high-risk patients for the decision to delayed extubation.Optimizing four modifiable factors, including BMI, FEV1/FVC, TPVB usage, and operation later than 6 p.m. may reduce the risk of delayed extubation.

Thymic epithelial tumors are the most common tumors of the anterior mediastinum, with an incidence of 0.18 per 100,000 population. Here, we present a review of the national and foreign literature on the surgical treatment of stage I and II thymic epithelial tumors. The Medline (PubMed) and Russian Science Citation Index (eLibrary) databases were used as search engines. The focus of the review is the problem of choosing the optimal minimally invasive surgical approach for thymectomy, and the need for lymph node dissection for thymic epithelial tumors. A number of issues remain currently unresolved in thymic epithelial tumors surgery, namely the justification of the preoperative histological verification of the tumor process, the choice of the optimal surgical access to the anterior mediastinum, the need for and prognostic effect of lymph node dissection, and the determination of the required volume of the planned operation.

Abstract Introduction The efficacy of erector spinae plane block versus paravertebral block for thoracoscopic surgery remains controversial. We conduct a systematic review and meta-analysis to explore the impact of erector spinae plane block versus paravertebral block on thoracoscopic surgery. Methods We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through March 2022 for randomized controlled trials (RCTs) assessing the effect of erector spinae plane block versus paravertebral block on thoracoscopic surgery. This meta-analysis is performed using the random-effect model. Results Seven RCTs are included in the meta-analysis. Overall, compared with erector spinae plane block for thoracoscopic surgery, paravertebral block results in significantly reduced pain scores at 12 h (SMD = 1.12; 95% CI 0.42 to 1.81; P = 0.002) and postoperative anesthesia consumption (SMD = 1.27; 95% CI 0.30 to 2.23; P = 0.01), but these two groups have similar pain scores at 1-2 h (SMD = 1.01; 95% CI − 0.13 to 2.15; P 0.08) and 4–6 h (SMD = 0.33; 95% CI − 0.16 to 0.81; P = 0.19), as well as incidence of nausea and vomiting (OR 0.93; 95% CI 0.38 to 2.29; P = 0.88). Conclusions Paravertebral block may be better for the pain relief after thoracoscopic surgery than erector spinae plane block.

Objectives: The prevalence of minimally invasive surgeries has increased the need for tumor detection using thoracoscopic images during lung cancer surgery. We conducted this study to analyze the efficacy of a deep convolutional neural network (DCNN) for tumor detection using recorded thoracoscopic images of pulmonary surfaces. Materials and methods: We collected 644 intraoperative thoracoscopic images of changes in pulmonary appearance from 427 patients with lung cancer between 2012 and 2021. The lesion areas on the thoracoscopic images were detected by bounding boxes using an advanced version of YOLO, a well-known DCNN for object detection. The DCNN model was trained and evaluated by a 15-fold cross-validation scheme. Each predicted bounding box was considered successful detection when it overlapped more than 50% of the lesion areas annotated by board-certified surgeons. Results and conclusions: Precision, recall, and F1-measured values of 91.9%, 90.5%, and 91.1%, respectively, were obtained. The presence of lymphatic vessel invasion was associated with successful detection (p = 0.045). The presence of pathological pleural invasion also showed a tendency toward successful detection (p = 0.081). The proposed DCNN-based algorithm yielded an accuracy of more than 90% tumor detection. These algorithms will help surgeons detect lung cancer displayed on a screen automatically. [ABSTRACT FROM AUTHOR]

Background: Patch repair of congenital diaphragmatic hernia (CDH) using Gore-Tex® is associated with infection, adhesions, hernia recurrence, long-term musculoskeletal sequels and poor tissue regeneration. To overcome these limitations, the performance of two novel biodegradable membranes was tested to repair CDH in a growing pig model. Methods: Twelve male pigs were randomly assigned to 3 different groups of 4 animals each, determined by the type of patch used during thoracoscopic diaphragmatic hernia repair (Gore-Tex®, polycaprolactone electrospun membrane-PCLem, and decellularized human chorion membrane-dHCM). After 7 weeks, all animals were euthanized, followed by necropsy for diaphragmatic evaluation and histological analysis. Results: Thoracoscopic defect creation and diaphragmatic repair were performed without any technical difficulty in all groups. However, hernia recurrence rate was 0% in Gore-Tex®, 50% in PCLem and 100% in dHCM groups. At euthanasia, Gore-Tex® patches appeared virtually unchanged and covered with a fibrotic capsule, while PCLem and dHCM patches were replaced by either floppy connective tissue or vascularized and floppy regenerated membranous tissue, respectively. Conclusion: Gore-Tex® was associated with a higher survival rate and lower recurrence. Nevertheless, the proposed biodegradable membranes were associated with better tissue integration when compared with Gore-Tex®. [ABSTRACT FROM AUTHOR]

Background: Congenital bronchial atresia (CBA) is a rare bronchial abnormality. Adult patients with CBA generally do not show any symptoms. Although surgical resection is the first-line treatment, the indication for the surgical intervention is controversial, especially in mildly symptomatic or asymptomatic patients. Recently, thoracoscopic surgery is the commonly preferred approach to treat this condition. Case presentation: Case 1: A woman in her 20s suffered from repeating episodes of fever and cough due to left CBA with the interruption of B9 and B10. Uniportal thoracoscopic left lower lobe wedge resection was performed, following which the symptoms disappeared. Case 2: A woman in her 40s presented to the clinic with dyspnea on exertion, and the computed tomography image revealed the absence of B2. Multiportal thoracoscopic right S2 segmentectomy was performed on her, after which the symptoms of dyspnea improved. Case 3: A woman in her 40s visited the hospital with symptoms of intermittent cough, sputum, and slight fever for 7 months. The examinations identified the absence of B6a. Right S6 segmentectomy and S2 wedge resection were carried out by multiportal thoracoscopic approach. The patient is now asymptomatic. Conclusions: Based on our experiences in the three adult CBA surgery cases, the three-dimensional image reconstruction system is very useful for diagnosis and surgical decisions with regard to this disease. Even for CBA patients with subtle symptoms, early surgical treatments may be beneficial from the point of view of minimally invasive interventions, and sublobar resection will be sufficient for treatments and preservation of respiratory function.

- Abstract
Objective To investigate the effect of driving pressure (DP) guided ventilation strategy on regional cerebral oxygen saturation (SrcO2) in infants with one lung ventilation (OLV) during thoracoscopic surgery. Methods Sixty infants undergoing elective thoracoscopic surgery were randomly divided into control group (group C, n = 30)and driving pressure group (group DP, n = 30). Near infrared spectroscopy was used to monitor SrcO2 during OLV. Cerebral oxygen desaturation (COD)was defined as SrcO2 decreased by more than 20% from baseline. The incidence of hypotension, time of ventilation rescue, the incidence of COD and its duration during OLV were recorded. MAP, HR, SrcO2, PEEP, airway peak pressure (Ppeak), static lung compliance (Cs) were recorded before (T1), 30 min after (T2) and 60 min after (T3)artificial pneumothorax, and results of arterial blood gas analysis on T1 and were T2 compared. Results There were no significant differences in the SrcO2 baseline, the mean SrcO2 during OLV, the incidence of hypotension and the incidence of COD between the two groups (P > 0.05). Times of ventilation rescue and COD duration in DP group were lower than those in C group (P < 0.05). There were no significant differences in MAP, HR, SrcO2, Ppeak, Cs, PaO2 and OI between the two groups at T1 (P > 0.05). Compared with T1, Ppeak increased and SrcO2 and Cs decreased in both groups at T2 and T3 (P < 0.05). Compared with group C, group DP had higher PaO2 and OI at T2, lower Ppeak and higher PEEP and Cs at T2 and T3 (P < 0.05). Conclusion DP guided ventilation strategy improved lung compliance, increased oxygen saturation and shortened the exposure of COD in infants during OLV. [ABSTRACT FROM AUTHOR]

Surgical approaches for traumatic diaphragmatic hernia include transabdominal, transthoracic, and thoracoabdominal. Selection of the optimal approach depends on the timing and organ damage, often minimally invasive approaches with laparoscopy or thoracoscopy are performed. A 47-year-old man with blunt chest trauma was diagnosed with left traumatic diaphragmatic hernia 1 month after the trauma. The prolapsed omentum was detached from the chest wall and around the hernia orifice and returned to the abdominal cavity by coordinated thoracoscopic and laparoscopic manipulations. The 4 x 2 cm herniation in the diaphragm was sutured closed from the thoracic side while preventing re-prolapse of the omentum and abdominal organs from the abdominal side. A combined thoracoscopic and laparoscopic approach can be effective in confirming organ damage, repositioning of prolapsed organs, and safe repair of the diaphragm in latent traumatic diaphragmatic hernia.
