[Videothorascopic surgery--initial experience].

Practical experience with the miniinvasive laparoscopic technique in abdominal surgery logically led to extension of this method to thoracic surgery. Video-assisted thoracoscopic operations hold their place in the treatment of spontaneous pneumothorax, pleural syndrome, benign tumours of the thoracic wall etc. A curative solution of malignant diseases by this route is so far controversial and is reserved only for specially defined cases. Experience from the authors' department is based on nine-month use of a thoracoscopic apparatus. The authors operated a total of 21 patients thoracoscopically, incl. pneumothorax 6x, fluidothorax 10x and tumourous disease of the lungs or mediastinum 5x. The use of thoracoscopy is controversial in metastases of the lungs and in thymectomy. With regard to the authors are against thoracoscopic indications in the latter conditions contemporary technical possibilities.

[Video-assisted surgery for closure of persistent ductus arteriosus. Study in sheep and initial clinical experience].

PURPOSE: The aim of this study was to analyse the effectiveness of patent ductus arteriosus (PDA) closure by the video-assisted thoracic surgery (VATS). METHODS: The technique was utilized in 6 newborn lambs firstly. Three to four small incisions (3 to 10mm) were used in each animal to permit the introduction of lung retractors, video equipment, dissectors and clip appliers. The procedure was accompanied by video monitoring and after the dissection, the PDA was closed by 2 titanium clips. Seven days after, the animals were sacrificed and submitted to pathological study. Based on this initial experience seven patients (ages between 17 and 108 months) were operated on with this technique. RESULTS: In lambs, we have some difficulty to retract the lung. Despite this fact the closure of PDA was successful and proved by pathologic study. In children the dissection of PDA was easier due to manual ventilation. The interruption of PDA using the proposed method was obtained in 4 patients, those with good relation between ductus diameter and clip size and defined by echocardiography and angiographic studies. CONCLUSION: The use of VATS for interruption of PDA in both, experimental and initial clinical experiences, has showed to be an effective method.

[Round pulmonary lesions after returning from French Guyana. Six cases of american pulmonary histoplasmosis].

From 1989 to 1994, 71 patients were hospitalized for diagnosis of round lung lesions including 49 servicemen under the age of 45 years who had been stationed in tropical areas. In 6 of these servicemen, the diagnosis was pulmonary histoplasmosis at the tertiary stage of histoplasmoma. All had done duty in French Guyana and were negative for human immunodeficiency virus. The subpleural lung opacity was the only lesion in 5 out of 6 patients and was calcified in 4 out of 6 patients. Since skin tests with histoplasmin and serologic testing for histoplasmosis failed to achieve definitive diagnosis, surgical biopsy was performed by conventional thoracotomy in 2 cases and video-assisted thoracic surgery in 4 cases. The specimens obtained confirmed diagnosis of histoplasmosis on mycologic criteria in 3 cases and on a combination of findings including compatible histologic evidence in 3 cases. Treatment consisted in surgical excision of the nodules, for which video-assisted thoracoscopic surgery proved to be an excellent technique because of its simplicity and rapidity.

One hundred consecutive patients undergoing video-assisted thoracic operations.

Video-assisted thoracic surgery is a new modality that allows visualization of and access to the intrathoracic organs without making a thoracotomy incision. One hundred consecutive patients underwent 113 thoracic procedures using this technique. Eight wedge resections for metastatic lesions, 6 pericardial windows, 1 bronchogenic cystectomy, 4 explorations of the aortopulmonary window, 1 decortication, 5 pleural scleroses, 8 bullous ablations, 25 lung biopsies, 19 wedge resections for carcinoma, 9 explorations of the thorax, 3 lobectomies, 1 esophageal cystectomy, 14 wedge resections for benign lesions, 4 pleurectomies, 1 excision of a neurogenic tumor, 3 mediastinal explorations, and 1 imaged axillary dissection were performed. There was no mortality. Ten patients had complications from which they recovered completely. Patients undergoing video-assisted thoracic operations seem to have reduced postoperative pain, shorter hospitalization, and quicker recovery times. Currently, this new modality appears to have beneficial value for patients; however, only further experience will determine its true merits.

Video-assisted thoracic surgical repair of a foramen of Bochdalek hernia.

A case report of a congenital posterolateral diaphragmatic hernia in an adolescent is presented and a technique for thoracoscopic repair of Bochdalek hernia is described. Postoperative discomfort was minimal and the hospital stay was less than 24 hours. Video-assisted thoracic surgery may be the technique of choice for repair of certain congenital diaphragmatic hernias when identified after infancy.

Recurrent bronchogenic pseudocyst 24 years after incomplete excision. Report of a case.

Bronchogenic cysts (BCs) are uncommon congenital anomalies. Due to the inherent complications, the mere presence of a BC should warrant surgical therapy. Partial excision of these structures leads to recurrence. Complete surgical excision using a thoracotomy or video-assisted thoracic surgery is the goal. We report a case of recurrent bronchogenic pseudocyst 24 years after initial excision. This case supports the argument for complete surgical excision of BCs at the time of diagnosis.

Study of endoscopic staple formation by specimen radiography on pulmonary wedges.

The advent in video-assisted thoracic surgery has rendered us to rely more and more on mechanical devices. We prospectively studied staple formation on resected lung specimen by radiography and attempted to correlate this with the clinical outcome. From February 1994 to January 1995, 36 consecutive pulmonary wedges (23 apical bullae, 12 pulmonary metastases, 1 tuberculoma) from 31 patients who had undergone resection by endoscopic staple-cutter (Endo GIA30, USSC) were examined by two-plane radiography for staple alignment and closure. Imperfect staple formation was found in 21 (58%) of resected specimens. The median size of the resected bullae is 4.2 mL (range, 2.0 to 58.8 mL) compared with 36 mL (range, 1.2 to 222.8 mL) in the resected metastases and tuberculoma specimen. Despite detecting more imperfect staples in the metastases group (77% vs 57%), there was little difference in the two groups with respect to postoperative chest drainage duration (median, 3 vs 2 days) or hospital stay (median, 2 vs 2 days). We conclude that the currently available endoscopic staplers are by no means perfect, especially for resection of larger specimens, even though this may not be apparent clinically. A continuous search for improvement in endoscopic staplers designed specifically for lung resection is needed.

[Palliative treatment of malignant effusions by thoracoscopy under video-assistance: morbidity and survival].

Survival after surgical palliation of patients with malignant pleural effusions is expected to be of several months. From a group of 75 patients operated by video-assisted thoracic surgery (VATS) from September 1991 through March 1993, twenty-two of 38 patients with malignant disease underwent palliative surgery and operative morbidity and length of survival were studied. Palliation consisted in 20 talc pleurodesis and 2 pericardial windows for malignant effusions. In the 16 other patients with malignancy, video-thoracoscopy was done for diagnostic purposes. Thirty-day operative mortality was 13.6% (3/22) and the rate of operative morbidity was 31.8% (7/22). The follow-up was complete for all patients with a mean length of 5 months (+/- sd 4 months). During the follow-up period, 14 of 19 (74%) patients, alive 30 days after the procedure, were deceased at a mean of 3.4 +/- 4 months (6 patients < 3 months) after the operation. In all, 9 of 22 patients (40%) survived less than 3 months (median survival 4 months). Operative morbidity and mortality of video-thoracoscopy are high in the palliative group and only 60% of patients survived more than 3 months. More stringent criteria for selection of patients for palliative endosurgery should be defined.

Thoracic incisions.

There are many ways to gain access to the chest. In recent years, there has been a rediscovery of the clamshell incision, an evolving concept of the utility incision for video-assisted thoracic surgery (VATS), and a continued emphasis on the importance and usefulness of the muscle-sparing axillary thoracotomy, which continues to be the author's most frequently used incision.

Comparison of ultrasound-guided two-point block of the rhomboid intercostal vs. thoracic paravertebral for postoperative analgesia in patients undergoing three-port thoracoscopic surgery: a prospective, randomized, non-inferiority study.

BACKGROUND: The anesthetic characteristics of ultrasound-guided two-point rhomboid intercostal block (RIB) have not been fully established. This study compared the analgesic efficacy of ultrasound-guided two-point RIB with that of two-point thoracic paravertebral block (TPVB) for postoperative pain control and recovery in patients undergoing three-port thoracoscopic surgery. METHODS: Seventy patients aged 18-80 years scheduled for three-port thoracoscopic pulmonary resection were block-randomized in a 1:1 ratio to receive either TPVB or RIB. Both techniques were performed using 10 mL of 0.5% ropivacaine at each injection site. The primary outcome was the numerical rating scale (NRS) pain score at rest 24 h after surgery, with a predefined non-inferiority margin of Δ = 1. Secondary outcomes included NRS at rest and during coughing at 0.5, 2, 4, 12, 18, 24, and 48 h postoperatively, as well as the 24h postoperative Quality of Recovery-40 (QoR-40) score. RESULTS: The final analysis included 34 patients in the TPVB group and 34 in the RIB group. The mean difference in resting NRS scores at 24 h between the two groups was 0.088 (95% CI, -0.377 to 0.553), confirming the non-inferiority of RIB. However, the need for rescue analgesia was numerically greater in the RIB group than in the TPVB group (p = 0.045). The 24-h postoperative QoR-40 scores and cumulative sufentanil consumption within 48 h after surgery were comparable between the groups (both p > 0.05). CONCLUSION: Ultrasound-guided two-point RIB provided postoperative analgesia that was non-inferior to TPVB in patients undergoing three-port thoracoscopic surgery.

Successful utilization of a video-assisted thoracic approach to repair Morgagni's hernia: report of a case.

We describe herein the successful utilization of a video-assisted thoracic surgical approach to repair Morgagni's hernia. The patient was a 62-year-old woman in whom a routine chest X-ray had revealed an asymptomatic mass, which was presumed to be a pericardial lipoma or Morgagni's hernia. The video-assisted thoracic surgical approach was combined with a right submammary minithoracotomy to successfully repair the hernia without performing a laparotomy. The patient's postoperative course was uneventful and she was discharged 14 days after surgery. Thus, we believe that video-assisted thoracic surgery may be a useful and effective method for repairing Morgagni's hernia.

Dexamethasone as an adjuvant to continuous erector spinae plane block for postoperative analgesia after video-assisted thoracoscopic surgery for pulmonary nodule surgery: a randomized controlled trial.

BACKGROUND: While dexamethasone is proven to enhance single-shot erector spinae plane block (ESPB), its role as an adjuvant in continuous ESPB catheters is unclear. This randomised controlled trial evaluated whether adding dexamethasone to ropivacaine improves analgesia after video-assisted thoracoscopic surgery (VATS). METHODS: 85 patients undergoing VATS with continuous ESPB were randomised to receive postoperative infusion of either 0.2% ropivacaine(C-ESPB group) or ropivacaine with 10 mg dexamethasone(D + C-ESPB group). The primary outcome was resting pain visual analog scale (VAS)at 12 h postoperatively, while secondary outcomes included QoR-15 scores, tramadol consumption, time to first analgesic requirement, postoperative adverse events, 3-month incidence of chronic pain, catheter-related complications, pain intensity at other times, and hospital stay. RESULTS: The D + C-ESPB group had significantly lower resting pain at 12 h [2.56 (1.03) vs 3.24 (1.21), mean difference -0.680, p = 0.006]; and lower coughing pain at 12 h [4.60 (1.48) vs 5.69 (1.35), mean difference 1.086, p < 0.001], with analgesic superiority sustained through 72 h. Quality of Recovery-15 scores were higher at 12 h [124.70 (12.48) vs 117.26 (12.24); mean difference -7.436, p = 0.007] and 48 h [141.60 (5.51) vs 138.98 (6.64); mean difference -2.628, p = 0.050]; Total tramadol consumption over 72 h was markedly reduce [0 (0,100) vs 100 (75,100), z = -3.807, p < 0.001], and hospital stay was shorter [Mean (SD) 6.09 (1.34) d vs 6.93 (1.55)d, p < 0.001]. The intervention did not, however, alter the 3-month incidence of chronic postsurgical pain (31% vs 34%, p = 0.756). CONCLUSION: Dexamethasone significantly enhances the analgesic efficacy of continuous ESPB, improving early pain control, recovery quality, and opioid-sparing after VATS, but does not reduce the incidence of chronic persistent surgical pain.

The incidence of complications in endoscopic anterior thoracolumbar spinal reconstructive surgery. A prospective multicenter study comprising the first 100 consecutive cases.

STUDY DESIGN: A prospective multicenter study on 100 consecutive surgical procedures. OBJECTIVES: A prospective multicenter study was performed to evaluate the early perioperative complications in 100 endoscopic spinal procedures--78 video-assisted thoracic surgical procedures and 22 laparoscopic lumbar instrumentation and fusion procedures. SUMMARY OF BACKGROUND DATA: Endoscopic procedures have been widely applied in general surgery for appendectomy, cholecystectomy, liver resection, Nissen fundoplication, colon resection, and hernia repairs. Video-assisted thoracic surgery is widely used for pleural biopsy, lung resection, and sympathectomy. This is the first large series to date investigating the safety and potential complications using endoscopic surgery for anterior decompression or fusion of the thoracolumbar spine. METHODS: Video-assisted thoracic surgical procedures included multilevel anterior thoracic releases for deformity, 27 patients; anterior thoracic discectomies with spinal canal decompression, 41 patients; pyogenic vertebral osteomyelitis decompression, 2 patients; and vertebral corpectomy for neurologic decompression, 8 patients. Mean operative time was 2 hours, 34 minutes (range, 45 minutes to 6 hours), and mean length of stay was 4.97 days (range, 2-21 days). Anterior laparoscopic interbody stabilization and fusion at L4-5 or L5-S1 was performed in 22 patients. The mean operative time was 4 hours, 17 minutes (range, 2 hours, 40 minutes to 9 hours), and the mean length of stay was 5.6 days (range, 1-23 days). RESULTS: The most common video-assisted thoracic surgical complications were transient intercostal neuralgia (six patients) and atelectasis (five patients). The most common laparoscopic complication was bone graft donor site infection (two patients). There were two endoscopic cases that were converted to open procedures, one for extensive pleural adhesions and one for a common iliac vein laceration. CONCLUSIONS: The endoscopic spinal approaches proved to be safe operative procedures in 100 consecutive cases. There were no permanent iatrogenic neurologic injuries and no deep spinal infections.

Thoracic paravertebral block with different doses of liposomal bupivacaine versus ropivacaine for postoperative analgesia in single-port thoracoscopic lung surgery: a randomized clinical trial.

OBJECTIVE: To evaluate the analgesic efficacy of thoracic paravertebral block (TPVB) with different doses of liposomal bupivacaine (LB) or ropivacaine in patients undergoing single-port thoracoscopic lung surgery. METHODS: A total of 105 patients scheduled for video-assisted single-port thoracoscopic lung surgery were randomized in a 1:1:1 ratio into three groups: low-dose LB group (group LL), high-dose LB group (group HL), or ropivacaine group (group R). All received ultrasound-guided TPVB at the T5/6 level preoperatively. The primary outcome was the area under the curve (AUC) of NRS of pain at activity (AUC-aNRS) from 1 to 72 h postoperatively. Secondary outcomes included the AUC of NRS of pain at rest (AUC-rNRS) from 1 to 72 h postoperatively, NRS of pain at rest and at activity at 1, 6, 24, 48, and 72 h postoperatively, and the cumulative opioid consumption at 24, 48, and 72 h postoperatively. Additionally, postoperative recovery and adverse events were assessed. RESULTS: AUC-aNRS differed significantly among groups (p = 0.0092), with high-dose LB lower than low-dose LB (p = 0.0071), but not versus ropivacaine. No significant difference was found in AUC-rNRS (p > 0.05). The group-by-time interactions for NRS of pain at rest and at activity were not significant (p > 0.05). Cumulative opioid consumption at 24, 48, and 72 h was lower in group HL versus group LL (all p < 0.017), but not versus ropivacaine. Postoperative recovery and adverse events showed no differences (p > 0.05). CONCLUSION: LB combined with TPVB is not superior to ropivacaine for postoperative analgesia in single-port thoracoscopic lung resection.

The safety and versatility of video-thoracoscopy: a prospective analysis of 895 consecutive cases.

BACKGROUND: The application of video-endoscopy to general thoracic surgery is radically changing the approach to many benign and malignant diseases of the chest. Since July 1991, we have performed 794 purely thoracoscopic and 101 video-assisted thoracic surgical (VATS) procedures on 860 patients. STUDY DESIGN: Comprehensive, prospectively acquired data examining the specific indications for and outcomes of this new technique were prospectively entered into a thoracic surgical database. Preoperative, intraoperative, postoperative, and outcome variables were studied for the entire group as well as three high-risk cohorts: age over 70 years (n = 198), forced expiratory volume in one second (FEV1) of less than 1 L (n = 46), and Karnofsky performance index of less than 8 (n = 61). RESULTS: The 895 cases involved 449 men and 446 women of ages 15 to 89 years (mean 56 +/- 16 years standard deviation). The indications for surgery were diagnostic in 501 cases (56 percent), therapeutic in 244 cases (27 percent), and both diagnostic and therapeutic in an additional 150 cases (17 percent). The specific procedures performed were operations on the lung (569 cases), pleura (196 cases), esophagus (42 cases), mediastinum (51 cases), and pericardium (37 cases). Fifty-seven percent of the procedures were for a malignant process and 43 percent were for benign or infectious pathology. There were nine deaths for a series operative mortality rate of 1.0 percent. Thirteen patients (1.4 percent) required conversion to a limited thoracotomy for technical reasons. There were 127 complications in 121 patients yielding a morbidity rate in all patients of 14 percent. Mortality rates in the elderly, poor lung function, and depressed performance index cohorts were 1.5, 2.1, and 9.8 percent, respectively. Morbidity rates in these high-risk populations were 19, 30, and 18 percent, respectively. The median postoperative length of stay was three days after closed thoracoscopy and five days after VATS resection. CONCLUSIONS: These data underscore the flexibility, safety, efficacy, and potential for cost savings of videoscopic surgery in patients with thoracic diseases. The ability to perform excisional biopsy improves diagnostic specificity and sensitivity to nearly 100 percent. Video-assisted thoracic surgical techniques also offer a minimally invasive procedure with acceptable risk to patients heretofore inoperable by standard thoracotomy.

Video-assisted thoracoscopic resection of intercostal neurofibroma.

BACKGROUND Video-assisted thoracoscopy (VAT) is being increasingly utilized by thoracic surgeons as an alternative to thoracotomy for several thoracic disorders. Neuroendoscopy is an exciting addition to the neurosurgical armamentarium. These procedures are attractive alternatives in the era of minimally invasive surgery and cost containment, while providing the highest quality medical care to patients. METHODS We report the application of this technology in a patient presenting with intractable thoracic radicular pain secondary to an intercostal neurofibroma. Complete excision of the intercostal neurofibroma was performed utilizing VAT. RESULTS The patient reported good relief of her preoperative thoracic radicular pain. She was ready for discharge from the hospital within 72 hours of surgery. CONCLUSIONS With the advent of improved instrumentation, video-assisted thoracoscopy offers a safe alternative to thoracotomy and the potential benefits of less postoperative discomfort and shorter hospital stays. The potential neurosurgical applications of VAT should not be overlooked.

Video-thoracic surgery for treatment of end-stage bullous emphysema and chronic obstructive pulmonary disease.

Surgical treatment of emphysema and chronic obstructive pulmonary disease (COPD) has received renewed attention because of advances in instrumentation and techniques. Our approach includes video-assisted thoracotomy, neodymium-Yag and KTP laser plication of emphysematous bullae, pulmonary resection using reinforced stapling, and pleurodesis: reduction pneumonoplasty. In a 9-month period, 28 patients (age 52 to 78, 23 men and 5 women) with end-stage disease underwent reduction pneumonoplasty. Oxygen therapy was required in 82 per cent, steroid therapy was used in 86 per cent, and the preoperative FEV1 averaged 0.68 +/- 0.05. The most severely diseased lung was determined by physical, chest film, and CT scan, and this lung had reduction pneumonoplasty. There were no hospital mortalities. Prolonged postoperative air leaks occurred in 42 per cent of patients. Postoperatively FEV1 was 0.91 +/- 0.35. Lung size (chest film) showed 21.6 per cent reduction in volume. Subjective improvement was noted in 78.6 per cent (22/28) of patients, and no patient reported worse symptoms. Half of the steroid-using patients required a reduced steroid dose or no steroid therapy, and 5/23 (21.7%) patients had reduced oxygen requirements. Reduction pneumonoplasty can improve the symptoms of severe emphysema and COPD. Our results with treatment of one lung suggest that further improvement may be anticipated by proceeding with surgery for the contralateral lung.
