Video-assisted thoracic surgical resection of malignant lung tumors.

Forty patients with malignant pulmonary disease underwent evaluation, staging, and a biopsy or resection by means of video-assisted thoracic surgery. There were 20 men and 20 women whose ages ranged from 27 to 82 years. Eight patients had a wedge resection for metastatic carcinoma, three a lobectomy for primary carcinoma, six exploration of the thorax, five biopsy of the aortopulmonary window, and eighteen a sublobar resection for primary carcinoma of the lung. There was no mortality. Three patients had air leaks that lasted an average of 8 days. Video-assisted thoracic surgery seems to be useful for more precise staging of carcinoma of the lung, and, in some patients, resectional operations can be performed.

Localization of pulmonary nodules before thoracoscopic surgery: value of percutaneous staining with methylene blue.

OBJECTIVE: Video-assisted thoracic surgery (VATS) is a new procedure that makes it possible to see the intrathoracic organs and to resect pulmonary nodules without thoracotomy. Preoperative localization of small nodules that may not be visible or palpable during VATS is desirable. Percutaneous placement of spring hookwires is widely used to localize pulmonary nodules before VATS; infrequently, the adjacent lung parenchyma is also stained with methylene blue. The purpose of this study was to evaluate the effectiveness of methylene blue staining of pulmonary nodules without placement of a hookwire. SUBJECTS AND METHODS: Fifteen pulmonary nodules in 15 patients were localized preoperatively under CT guidance by using techniques identical to those for CT-guided fine-needle aspiration of pulmonary nodules. Approximately 0.3 ml of methylene blue dye was injected into the nodule with a 22-gauge Chiba needle to stain the nodule, the needle pathway, and the visceral pleura. In two patients, a hookwire also was placed. All patients had solitary nodules in which transbronchial or transthoracic biopsy had been unsuccessful. The mean nodule diameter was 16 mm (range, 8-33 mm), and the mean distance to the nearest pleural surface was 10 mm (range, 0-21 mm). The localization procedure required a mean of 32 min (range, 18-47 min). RESULTS: All 15 nodules were stained successfully either in the center or within the margins; the two hookwires were found to be displaced. In three cases, pulmonary hemorrhage occurred as a complication of the percutaneous staining procedure: in one case, subsequent conversion to thoracotomy was necessary owing to pulmonary hemorrhage and additional pleural bleeding during VATS, which resulted from puncture with a trocar directly into the pleural adhesions. Anticipated complications, such as pneumothorax, occurred in five patients; one patient had pleuritic pain, but none required treatment. In one patient, conversion to thoracotomy was done so that an adenocarcinoma could be treated by means of a lobectomy. In two others, thoracotomy was done because of problems with technical devices. CONCLUSIONS: Percutaneous staining of pulmonary nodules is an accurate technique for localizing nodules before VATS. The procedure is easily and safely performed, and it obviates wire-related complications, such as severe pleuritic pain.

[New techniques in thoracic surgery. II].

The surgical approach to affections of the chest wall and pleura, still the predominant indications for thoracic surgery, has greatly changed since the advent of thoracoscopic procedures, and is emphasized in this second part of a two-part review, together with other indications for mediastinal tumours. Indicated after lung exeresis or emergency chest surgery, protective chest wall reconstruction with muscular flaps is no longer an exceptional operation. Inversely, thoracic surgery for infectious complications have become less frequent, unusually limited to well established procedures for tuberculosis surgery, treatment of bronchial fistula or mediastinal supperations. The chest cavity is well adapted to new techniques of thoracoscopy and video-assisted thoracic surgery both for diagnosis and treatment. Indications for pleuroscopy have taken on a completely new aspect since 1989. These techniques are used for pericardial fenestration, thoracic sympathectomy for dyshidrosis, vagotomy, splanchnicectomy, chylothorax, spinal affections, empyema and trauma surgery. These new techniques have also had an impact on treatment of spontaneous pneumothorax. For tumour surgery, thoracoscopy has made possible a more adapted strategy currently based on an initial needle biopsy, with limited thoracoscopic exeresis and ultimate treatment depending upon the pathology report. Immediate thoracoscopy without prior biopsy appears excessive. Video-assisted thoracosurgery is also used for most malignant mediastinal tumour which, due to advances in chemotherapy surgery have transformed the prognosis of a large number of mediastinal tumours.

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.

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 thoracoscopic thymectomy for myasthenia gravis.

Video-assisted thoracoscopic surgery (VATS) provides a new approach to thymectomy. From June 1993 to December 1994, we performed a total of eight thymectomies for myasthenia gravis (MG). There were four male and four female patients with ages ranging from 9 to 76 years. Three of the eight patients had associated thymoma. We believe that complete thymectomy was accomplished in all cases by examination of the thymic bed and resected specimen. There was no mortality or intraoperative complications. The median postoperative hospital stay was 5 days (range, 2 to 37 days). One patient required ventilatory support postoperatively. Clinical improvement was observed in all patients after a mean follow-up of 10 months (range, 2 to 21 months). Compared with a comparable historical group of patients with MG who underwent transsternal thymectomy, the VATS group was associated with significantly less analgesic requirement and shortened hospital stay. We conclude that VAT thymectomy is technically feasible and is associated with a favorable postoperative course compared with the transsternal approach. We believe that complete thymectomy can be achieved by this approach. Further investigation with long-term follow-up is needed to further clarify the role of VAT thymectomy in thoracic surgery.

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.

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.

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.

Video-assisted thoracoscopic wedge resections of pulmonary metastatic osteosarcoma: should it be performed?

We studied the use of video-assisted thoracoscopic (VAT) surgery in the management of metastatic osteosarcoma. From September 1993 to March 1994, we performed a total of 11 VAT wedge resections of pulmonary metastatic osteosarcoma in seven patients (six males, one female, age 12 to 46 years). Three patients had bilateral procedures performed either under the same anaesthesia or in stages. One patient had two operations on the same side. The average number of nodules excised was three. Two patients subsequently required formal lobectomies when the metastatic tumours were either too big or too close to the hilum for safe wedge resections. There was one death on postoperative day 3 due to dysrhythmia. One patient died 5 months later from a progression of his underlying disease. Two patients remained disease free up to 8 and 12 months, respectively, from their first operations. The average postoperative chest drain duration was 1.4 +/- 0.7 days and hospital stay 2.3 +/- 1.1 days. The procedure was well tolerated and postoperative morbidity was minimal. We conclude that although VAT wedge resection of pulmonary metastatic osteosarcoma is feasible technically and is associated with a short hospital stay and minimal morbidity, this approach cannot be recommended when complete resection of all metastases is the goal as the technique relies heavily on computed tomographic scans to detect nodules. Recurrence of metastasis from 4 to 6 months in three of seven patients argues against VAT surgery being an adequate procedure. The high cost of the staplers, in addition, is a secondary consideration.

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.

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.

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 anterior extra-peritoneal approach of the inferior lumbar spine].

PURPOSE OF THE STUDY: The aim of this study is to describe a new operative technique for anterior lumbar and lumbosacral fusion using a video assisted anterior extra peritoneal approach. MATERIAL: Ten patients were operated on. There were 3 men and 7 females. Age at operation ranged from 18 to 55. There were 8 degenerative and 2 iatrogenic discopathias. Fused level was L4-L5 (5 patients) and L5-S1 (5 patients). Average hospital stay was 6 days. METHODS: A small vertical 4-5 cm incision is made on the mid line, centered on the umbilicus for the approach to L4-L5, and between the umbilicus and pubis for the L5-S1 approach. The peritoneum is cleaved from the abdominal wall on the left side, and the anterior aspect of the spine is progressively freed. The endoscope is laterally introduced. It gives an excellent view of the prevertebral area. A specially designed retractor is used for retraction of the iliac vessels. Following removal of the intervertebral disc, a special spreader allows obtention of a normal intervertebral space height and insertion of an autogenous iliac graft. DISCUSSION: Anterior approach of the lumber intervertebral discs allows disc resection and grafting in a strict middle position. The extra peritoneal simplifies the postoperative course and avoids digestive and septic complications of the transperitoneal approach. The video assistance gives excellent exposure by a small incision with direct visual control; it should be differentiated form the true endoscopic lumbar surgery which is performed under C02 insufflation, with exclusive endoscopic vision and with instruments introduced through trocards. CONCLUSION: Video-assistance allows an approach to the lumbar and lumbosacral spine by an anterior non invasive extra peritoneal approach, with low morbidity, increasing the possibilities of anterior fusion in the treatment of lumbar discopathias and instability without radicular compromise.
