[The usefulness of thoracoscopic surgery for pleuritis carcinomatosa].

We performed thoracoscopic surgery for pleuritis carcinomatosa, in which re-expansion of the collapsed lung was impossible, by employing tube thoracostomy. One of the treatments used for pleuritis carcinomatosa was drainage of the pleural effusion followed by re-expansion of the collapsed lung. The decortication and biopsy of the pleura and the pleural effusion drainage with the thoracoscopic procedure were performed, allowing control of the pleural effusion and re-expansion of the collapsed lung to be accomplished. We conclude that thoracoscopic surgery is useful for the thoracic treatment of pleuritis carcinomatosa.

Pericardial cyst in a child treated with video-assisted thoracoscopic surgery.

UNLABELLED: A pericardial cyst is a rare condition in childhood. We report on a 10-year-old girl who presented with an intrathoracic mass detected on a chest X-ray performed during a routine medical examination. She had no symptoms and a physical examination revealed no abnormalities. Ultrasonography, computed tomography and magnetic resonance imaging showed a multiloculated cystic mass in the right upper thorax. The cyst was resected using a thoracoscopic procedure. Histologically, the findings were consistent with a pericardial cyst. Thoracoscopic surgery was an effective surgical technique even for such a young patient and the results successfully reduced the morbidity. CONCLUSION: A pericardial cyst, a rare condition in childhood, was treated successfully by video-assisted thoracoscopic surgery.

A 7-year experience with thoracoscopic sympathectomy for critical upper limb ischemia.

BACKGROUND: Severely symptomatic arterial insufficiency of an upper limb not suitable for revascularization is a difficult condition to manage. Thoracoscopic sympathectomy (TS) can be an effective procedure in this setting. METHODS: Our experience with 18 consecutive thoracoscopic sympathectomy (TS) procedures over a period of 7 years has been reviewed. Indications, operative technique, complications, and outcome of surgery are analyzed. RESULTS: We performed 18 TS procedures on 17 patients during this period. There were no deaths. One patient had intraoperative hemorrhage necessitating conversion to open thoracotomy. Mean postoperative hospital stay was 2.3 days. Follow-up ranged from 6 to 72 months. All patients demonstrated clinical benefit from the procedure. CONCLUSIONS: Thoracoscopic sympathectomy is a useful option in patients with severely symptomatic hand and digital ischemia from occlusive small arterial disease like thromboangitis obliterans.

Thoracoscopic surgery for spontaneous pneumothorax.

Spontaneous pneumothorax in apparently healthy individuals is a relatively common occurrence. The management of patients with spontaneous pneumothorax remains controversial. With the advances in thoracoscopic techniques and instrumentation, video-assisted thoracic surgery (VATS) is now accepted by many as the procedure of choice for surgical treatment of spontaneous pneumothorax. We report our combined experience with 757 patients who suffered from recurrent or persistent spontaneous pneumothorax treated by VATS over a 5-year period. Surgical indications included persistent air leak (n = 165), recurrence (n = 325), radiologically demonstrated huge bulla (n = 12), spontaneous hemopneumothorax (n = 13), incomplete expansion of the lung (n = 212), and bilateral involvement (n = 30). Several surgical procedures were undertaken, based on the thoracoscopic findings: endoscopic stapled bullectomy (n = 312), argon beam coagulation (n = 6), endoscopic suturing (n = 52), and endoloop ligation (n = 352). In 49 cases, mechanical or chemical pleurodesis was the only procedure performed. There were no mortalities or intraoperative hazards. Complications consisted of wound infections (n = 16), localized empyema (n = 2), chest wall bleeding (n = 1), and persistent air leaks (bulla type III) (n = 31). The median duration of the operation was 55 minutes (15-160 minutes), and the average postoperative hospital stay was 4.5 days (range 0-27 days). There were 16 recurrences (2.1%), after a mean follow-up of 30 months (range 1-60 months). Seven patients had recurrence from 9 to 17 months after stapled bullectomy. All the remaining patients had recurrence after failed pleurodesis. On the basis of our results, we conclude that video-assisted thoracoscopic management allows effective, safe performance of standard surgical procedures, avoiding a formal thoracotomy incision. We consider thoracoscopy the treatment of choice for patients with pneumothorax requiring surgical therapy.

Thoracoscopically assisted ligamentous release of the thoracic spine: a cadaver study.

The surgical treatment of thoracic kyphosis frequently requires an anterior release, which can be carried out by an open or endoscopic technique. This study concerns the reference points which are essential from the anatomic view for minimizing the operative risks. Furthermore we wanted to find the most convenient video-assisted thoracoscopic surgery (VATS) technique for transection of the anterior longitudinal ligament (ALL). Transection of the ALL, as well as discectomy, was performed using this technique. The extensive anatomic dissection of 12 fresh cadavers was performed to define possible technical errors and surgical complications. The development of new instruments has made the VATS approach to the ALL a viable alternative to open procedures. With the help of a standardized technique, the isolated thoracoscopic ligamentous transection required less time than the comparable open procedure. The anatomic study showed, that in no case was a ligation of the intercostal or segmental vessels necessary as part of the approach to the spine, once an adequate mobilization of the esophagus and azygos vein had been carried out. The risk of an ischemic lesion of the spinal cord was thereby reduced. The thoracoscopic, limited anterior release consisting of a multilevel transection of the ALL proved to be a rapid and reliable procedure. Our anatomic studies provides suitable the reference points.

Comparison of thoracoscopic drainage with open thoracotomy for treatment of paediatric parapneumonic empyema.

The purpose of this study was to compare the efficacy of thoracoscopic drainage with open drainage of empyema in children. A retrospective case history audit was done of children presenting to a single major paediatric centre who underwent thoracoscopy drainage and decortication or open decortication and drainage (thoracotomy) between January 2000 and September 2002. Time to resolution of infection, duration of intercostal catheter (ICC) drainage, postoperative morphine requirements, and length of hospital admission were compared as primary measures of outcome. Thirty-three patients, 17 male and 16 female, aged between 1 month and 21 years were included in the study. Median age at surgery was 2.6 years. The location of the empyema was right-sided in 17 patients and left-sided in 16 patients. The empyema was drained by thoracoscopy in 11 patients, and 22 patients underwent thoracotomy. Two patients had thoracoscopy converted to thoracotomy for late-stage disease requiring greater surgical access. There were no differences between treatment groups with respect to duration of ICC drainage (p=0.6), duration of fever (p=0.6), length of stay (p=0.9), or postoperative morphine use (p=0.2). However, overall pain scores were lower in the thoracoscopy group, particularly on days 2 and 3; this approached statistical significance (p=0.07). This study has demonstrated that thoracoscopic drainage is an effective procedure for treating empyema in children. It is less invasive than open thoracotomy and is associated with less patient discomfort and less severe pain as measured by objective pain scores. We advocate thoracoscopic drainage for the majority of patients with empyema, except for those with advanced disease.

Subxiphoid approach for thoracoscopic thymectomy.

Avoiding sternotomy, cumulative experience has demonstrated the efficacy and safety of minimally invasive thoracoscopic thymectomy. Previous reports describing the transcervical, left or right thoracic approach, although demonstrating promising results, involve some compromise of the surgical exposure. We designed a new approach through the subxiphoid route to perform extended thymectomy using the standard thoracoscopic technique. We used this approach on two consecutive patients. Additional port sites were created on both sides of the anterior chest wall for introducing instruments. This approach provides an excellent view of the bilateral pleural cavities, which is essential for adequate mediastinal fatty tissue dissection, especially because the surgical plan calls for removal of all the bilateral pericardiophrenic fat pads and the mediastinal fat tissue between the bilateral phrenic nerves. This approach omits the sternotomy while making extended thymectomy possible through the bilateral access. All the possible thymic-bearing mediastinal fat tissues can be removed under direct thoracoscopic view, which may subsequently translate into better results.

Thoracoscopic Belsey fundoplication with 5-year outcomes.

BACKGROUND: To determine the indications for a minimally invasive thoracic technique in gastroesophageal reflux disease (GERD), we conducted a retrospective review of outcomes with our first 21 thoracoscopic Belsey fundoplications. METHODS: A thoracoscopic Belsey fundoplication was completed in 21 patients (12 males, 9 female; ages, 38-83 years). Preoperative evaluation revealed 13 primary motility disorders, 9 strictures, and 3 epiphrenic diverticuli. Six patients had previous gastric surgery. Sixteen patients underwent 20 ancillary procedures (esophagomyotomy, 14; excision of diverticulum, 2; lung volume reduction, 2; prosthetic diaphragmatic repair, 1; and Thal-Woodward esophagoplasty, 1). RESULTS: Mean follow-up was 75.6 months (range, 67-85 months). There was one operative death (4.8%). Early morbidity included two esophageal leaks (9.8%). Late morbidity included three patients (15.7%) with persistent dysphagia and five patients (26%) with recurrent GERD. CONCLUSION: Thoracoscopic Belsey fundoplication was associated with a high morbidity and recurrence rate in our long-term experience.

Intrapleural analgesia following thoracoscopic sympathectomy for palmar hyperhidrosis: a prospective, randomized trial.

BACKGROUND: Reports on intrapleural analgesia (IPA) are conflicting. The current study assessed the effect of a single-dose thoracoscopic bilateral intrapleural anesthetic administration on the immediate postoperative recovery room and 24-h pain control. METHODS: Fifty patients with primary palmar hyperhidrosis were randomly classified into two groups to receive either 20 ml of 0.5% bupivacaine and 5 mg/ml epinephrine or 0.9% NaCl in each thoracic cavity at the end of thoracoscopic T2-T3 sympathectomy. The degree of early postoperative pain was estimated by visual analog scale (VAS). The 24-h parenteral opioid analgesic requirement was recorded. RESULTS: The immediate postoperative VAS score (1.46 +/- 0.41 vs 2.0 +/- 0.61, p = 0.03), opioid consumption (0.42 +/- 0.36 vs 0.65 +/- 0.28, p = 0.0133), and 24-h opioid consumption (1.02 +/- 0.80 vs 1.48 +/- 0.84, p = 0.05) were significantly reduced following IPA compared to those of the control group. CONCLUSION: IPA is a simple and effective means for postoperative pain control following thoracoscopic upper dorsal sympathectomy.

Video-assisted thoracoscopic esophagectomy and radical lymph node dissection for esophageal cancer. A series of 75 cases.

BACKGROUND: The efficacy of thoracoscopic radical esophagectomy for cancer has yet to be established, mainly because previous reports have not included a sufficient number of cases. METHODS: Seventy-five treatment-naive patients with esophageal cancer without contiguous spread underwent esophageal mobilization and extensive mediastinal lymphadenectomy through a 5-cm mini-thoracotomy and four trocar ports. RESULTS: Video-assisted thoracoscopic surgery was performed without major intraoperative complications or emergency conversion to open surgery. We retrieved 34.1+/-13.0 mediastinal nodes, including 11.5+/-3.8 tracheobronchial nodes and 6.2+/-3.0 recurrent laryngeal nodes. Mean time of operation and blood loss were less in the last 39 patients than the first 36 (186.7+/-25.3 min and 165.4+/-101.8 g vs 270. 2+/-96.0 min and 421.5+/-31.2 g, respectively: p <0.0001 and p <0.001). Pulmonary morbidity was 5% in the later 39 patients. Survival was 90%, 80%, and 57% at 1, 2, and 5 years after surgery. CONCLUSION: Thoracoscopic radical esophagectomy has less morbidity and comparable survival to conventional surgery, after a moderate amount of experience. Mini-thoracotomy is essential to perform the procedure safely and effectively.

Learning curve of video-assisted thoracoscopic esophagectomy and extensive lymphadenectomy for squamous cell cancer of the thoracic esophagus and results.

BACKGROUND: The efficacy of thoracoscopic radical esophagectomy for cancer of the thoracic esophagus and the learning curve required have yet to be clearly established. METHODS: Eighty treatment-naive patients with esophageal cancer without contiguous spread underwent esophageal mobilization and extensive mediastinal lymphadenectomy through a 5-cm minithoracotomy and four trocar ports. The outcomes in the first 34 patients (group 1) and the last 46 patients (group 2) were compared. RESULTS: There were no differences in background or clinicopathologic factors between the two groups. The duration of the thoracoscopic procedure and blood loss were less (p <0.0001), the incidence of postoperative pulmonary infection was less (p = 0.0127), and the number of mediastinal nodes retrieved was greater (p = 0.0076) in group 2. Multivariate analysis demonstrated that surgical experience (number of cases performed) predicted the risk of pulmonary infection (p = 0.0331). CONCLUSION: Video-assisted thoracoscopic radical esophagectomy can be performed with safety and efficacy comparable to those of open esophagectomy. Morbidity decreases with the surgeon's experience.

Thoracoscopic repair of esophageal atresia with distal fistula.

BACKGROUND: Esophageal atresia (EA) has always been considered the hallmark of pediatric surgery. In the past decade, mortality was primarily the result of associated diseases, and operative morbidity had greatly improved. Yet the consequences of opening the thoracic cavity remained unchanged. In the era of endoscopic surgery, a thoracic approach to EA has become feasible, but is it of benefit for the patient? METHODS: Between May 2000 and June 2002, 13 neonates underwent thoracoscopic repair of EA. There were 12 boys and 1 girl. Mean gestational age was 36.9 weeks. Mean weight was 3093 g. Eleven children had associated anomalies. RESULTS: All of the procedures were performed thoracoscopically. There were no intraoperative complications, although anastomosis was difficult in one patient due to an extensive distance between the two stumps. Mean operating time was 2.6 h (range, 1.45-3.5). Five short-term postoperative complications occurred. Four of the early patients had stenosis due to a too-small incision in the proximal pouch, which needed one or more dilatations. One of these children, as well together as one other child, had anastomotic leakage, which was treated conservatively. Late complications consisted of gastroesophageal reflux ( n = 5) and tracheomalacia ( n = 1); these conditions required endoscopic correction in, respectively, two and one cases. Feeding by nasogastric tube was started after 3.5 days (mean), and total oral feeding was possible after 8.6 days (mean). Mean hospitalization was 12.2 days. Mean follow-up was 15.2 months. Scar formation was minimal, and the thoracic cage was preserved. CONCLUSION: The feasibility of thoracoscopic repair of EA has already been demonstrated. Today, its results in terms of operating time, feeding, hospital stay, and postoperative complications are equal to open procedures. Its advantages include better cosmesis and preservation of the thorax.

Comparison of three-field esophagectomy for esophageal cancer incorporating open or thoracoscopic thoracotomy.

BACKGROUND: Thoracoscopic esophagectomy for esophageal cancer has been performed as an alternative to open surgery to reduce surgical trauma. However, its effect on pulmonary function, exercise tolerability, and quality of life is unknown. METHODS: Fifty-one patients with esophageal cancer underwent thoracic esophagectomy with radical lymphadenectomy by posterolateral thoracotomy (29 cases) or thoracoscopic surgery (22 cases). Patients performed spirometry and exercise tolerance testing and completed a quality-of-life questionnaire before and 3 months after surgery. RESULTS: Pre-to-postoperative change in vital capacity was 74.3 +/- 10.6% in the thoracotomy group and 84.9 +/- 10.4% in the thoracoscopy group (p = 0.021). Maximum oxygen uptake was similar, but dyspnea was the more common factor limiting exercise tolerance postoperatively in the thoracotomy group. Change in pre-to-postoperative performance status was 1.20 +/- 0.62 in the thoracotomy group and 0.55 +/- 0.51 in the thoracoscopy group (p = 0.0003). CONCLUSIONS: Thoracoscopic esophagectomy for esophageal cancer has better preservation of pulmonary function and quality-of-life.

Staple line coverage with absorbable mesh after thoracoscopic bullectomy for spontaneous pneumothorax.

BACKGROUND: Thoracoscopic simple bullectomy for primary spontaneous pneumothorax (PSP) has a relatively high postoperative recurrence rate and sometimes results in postoperative air leakage. One of the reasons for postoperative recurrence is the regrowth of bullae around the staple line. Therefore, reinforcement of the visceral pleura around the staple line is a reasonable way to prevent postoperative air leaks and recurrence. This study was done to determine the efficacy in preventing postoperative air leak and recurrent pneumothorax of widely covering the staple line with absorbable mesh after thoracoscopic bullectomy. METHODS: Wide coverage of the staple line with absorbable mesh was performed on 114 patients with PSP. These patients were retrospectively compared with 126 patients who underwent thoracoscopic simple bullectomy alone. RESULTS: The postoperative duration of chest drainage in the coverage group (mean, 1 day; range, 0-5) was significantly shorter than that in the simple bullectomy group (mean, 3 days; range 0-20). A prolonged air leak (>7 days) occurred in six patients in the simple bullectomy group, but there were no such leaks in the coverage group. Recurrent pneumothorax occurred in three patients (2.6%) in the coverage group and 12 patients (9.5%) in the simple bullectomy group. CONCLUSION: Wide coverage of the staple line with absorbable mesh is effective in preventing postoperative air leak and in decreasing the recurrence rates of PSP.

Results of thoracoscopic pleural abrasion for primary spontaneous pneumothorax.

BACKGROUND: Several video-assisted techniques have been used to treat primary spontaneous pneumothorax (PSP). The aim of this study was to evaluate the results of thoracoscopic pleural abrasion for PSP. METHODS: From 1991 to 2003, 185 consecutive patients, 143 male and 42 female, aged 15 to 60 years (average 31.6) underwent thoracoscopic pleural abrasion for PSP. The indications for surgery were as follows: a first episode with persistent air leak in 33 patients (17.9%), a recurrent ipsilateral pneumothorax in 122 patients (65.9%), a previous contralateral pneumothorax in 23 patients (12.4%), and recurrence after surgical treatment in seven patients (3.8%). Bullae were resected in 163 patients (88.1%). Mechanical pleural abrasion was performed in all cases. RESULTS: There were no deaths. Intraoperative hemorrhage occurred in three patients. It was controlled via thoracotomy in one patient and via thoracoscopy in two patients. The postoperative complication rate was 8.1% (15/185). Complications included prolonged air leak in eight patients (4.3%), pleural effusion in two (1.1%), extrapleural hematoma in one (0.5%), chest wall infection in one (0.5%), atelectasis in one (0.5%), and hemorrhage in two (1.1%). Postoperative hospital stay ranged between 2 and 17 days (mean, 5). Mean duration of drainage was 3.8 days (range; 1-16). Postoperatively, 111 patients were contacted, with a mean follow-up of 36.5 months. Four of them had a recurrence (3.6%) that did not require reoperation. CONCLUSION: Thoracoscopic pleural abrasion associated with bullae resection is a safe and efficient treatment for PSP. Results remain stable in the long term.

Pharyngolaryngoesophagectomy using the thoracoscopic approach.

BACKGROUND: Thoracoscopic mobilization of the esophagus for pharyngolaryngoesophagectomy allows dissection under direct vision, and therefore it potentially results in fewer complications than conventional transhiatal mobilization. In this article we report our experience with this approach. It was also hypothesized that a learning curve existed and that results have improved over time. PATIENTS AND METHODS: From July 1994 until January 2004, 57 patients underwent pharyngolaryngoesophagectomy in our institution. Intraoperative events and postoperative outcome were prospectively documented, and long-term follow-up data were also studied. Results were compared between the first 30 patients and the last 27 patients. RESULTS: There were no significant differences between the two groups with respect to the various clinicopathological characteristics. There was no difference in the median thoracoscopic time between the first 30 and last 27 patients at 90 and 75 min, respectively, p = 0.18. For the complete procedure there was significantly less blood loss in the later group; median (range) blood loss 700 (164-3000) ml versus 400 (100-1200) ml, p = 0.002. Overall pulmonary complications occurred in 12 patients (40%) in the first group versus 13 (48%) in the second group, p = 0.6. The incidence of atrial arrhythmia was also similar, affecting 6 (20%) patients and 3 (11%), respectively, p = 0.47. Hospital mortality rates were 13.3% and 7.4%, p = 0.67. Two-year survival rates were no different (46% versus 45% p = 0.85). CONCLUSIONS: Although, subjectively, operating skills have improved over time, better results in the second half of this series could not be demonstrated clearly, likely because the operating surgeons had prior extensive experience in esophageal and thoracoscopic procedures.

Thoracoscopically assisted total en bloc spondylectomy: two case reports.

We describe a combined surgical technique for tumors of the thoracic spine consisting of a thoracoscopically assisted ventral release followed by a dorsal en bloc spondylectomy and reconstruction. The technique enables thoracoscopic access and release of the involved spinal segment(s) to achieve surgical and histopathologic wide margins, avoiding the disadvantages inherent to thoracotomy. Two patients were successfully treated with solitary tumors involving T10 and T7-8 vertebra. The resection margins were free of tumor. Thoracoscopically assisted total en bloc spondylectomy allows wide excision of thoracic spinal tumors with free resection margins in selected patients; the operation can be performed under direct vision without contamination of uninvolved parts.

Thoracoscopic mobilization of the esophagus. A 6 year experience.

BACKGROUND: Traditionally, esophageal resection has been performed using a thoracotomy to access the intrathoracic esophagus. With the aim to avoid the potential morbidity of the open thoracic approach, mobilization of the esophagus under direct vision recently has been described. We report our experience at attempting thoracoscopic mobilization of the esophagus in 162 patients during a 6-year period. METHODS: Patients with malignancy or end-stage benign disease of the esophagus considered suitable for a three-stage esophagectomy underwent a thoracoscopy with a view to endoscopic mobilization of the esophagus. Of the 162 patients in whom the procedure was attempted, it was abandoned in 9 patients (6%), and the procedure was converted to open surgery in 11 patients (7%). RESULTS: In the patients whose esophagus was mobilized, the average blood loss was 165 ml, and the average time for the thoracoscopic segment of the surgery was 104 min. In the 133 patients who underwent a resection for invasive malignancy, a limited mediastinal nodal dissection retrieved an average of 11 nodes, and the median survival was 29 months. The 30-day mortality was 3.3% and the in-hospital mortality 5.3%. CONCLUSIONS: Thoracoscopic mobilization can be performed safely with satisfactory outcomes in a center performing a large volume of esophageal surgery and possessing advanced endoscopic surgery skills. Further assessment of this technique and comparisons with traditional open procedures are needed to assess this approach further as an appropriate oncologic procedure.
