Thoracoscopic sympathectomy for axillary hyperhidrosis: the influence of T4.

BACKGROUND: Recent data suggest that severe compensatory sweating after sympathectomy for hyperhidrosis is more common than previously reported. In particular, T2-T4 sympathectomy for axillary hyperhidrosis leads to significantly more disabling sweating compared with T2-T3 sympathectomy for palmar hyperhidrosis. However, it is not known whether this is a result of the additional transection of the T4 segment or if patients with primary axillary hyperhidrosis are more prone to experience disabling compensatory sweating. METHODS: A follow-up study by questionnaire was made of 100 consecutive patients who underwent thoracoscopic sympathectomy for axillary hyperhidrosis at two university hospitals. Patients underwent T2-T3 sympathectomy (n = 35) or T2-T4 sympathectomy (n = 65) depending on the surgeon's preference. RESULTS: The questionnaire was returned by 91% of patients after a median of 31 months. Compensatory sweating occurred in 90% of patients and was so severe in 61% that they often had to change clothes during the day. There were no significant differences in occurrence or severity of compensatory sweating between the two extents of sympathectomy. Surgical outcome, however, was significantly better after T2-T4 sympathectomy. CONCLUSIONS: In contrast with previous reports, the incidence of compensatory sweating was not significantly related to the extent of sympathectomy for axillary hyperhidrosis. This result suggests that patients with primary axillary hyperhidrosis are more prone to experience compensatory sweating. Although the majority of patients with axillary hyperhidrosis were satisfied after thoracoscopic sympathectomy, many regret the operation. Patients should undergo surgery only if medical treatments fail; and provided there is an indication, we recommend T2-T4 sympathectomy.

Robotic-assisted thoracoscopic surgery (RATS) for benign and malignant esophageal tumors.

BACKGROUND: Robotic surgical systems are most effective for operations in areas that are small and difficult to reach. Ideal indications for this new technology have yet to be established. The esophagus possesses attributes that are interesting for general thoracic robotic surgeons. METHODS: Robotic-assisted thoracoscopic surgery (RATS) using the da Vinci system (Intuitive Surgical, Inc, Mountain View, CA) was performed in six patients with esophageal tumors. This comprised the dissection of the intrathoracic esophagus including lymph node dissection in four patients suffering from esophageal cancer and the extirpation of a benign lesion (one leiomyoma and one foregut cyst) in the remaining two patients. RESULTS: All procedures were completed successfully with the robot. The median overall operating time was 173 (160-190) minutes in the oncologic cases and 121 minutes in the benign cases, including the robotic act of 147 (135-160) minutes and 94 minutes, respectively. There were no intraoperative complications. One patient had to undergo a redo thoracoscopy because of a persistent lymph fistula. One cancer patient died after 12 months due to tumor progression and another patient had to be stented due to local tumor recurrence 19 months postoperatively. CONCLUSIONS: This first small series of various esophageal pathologies treated by robotic-assisted thoracoscopic surgery supports the impression that the esophagus is an ideal organ for a robotic approach. The potential of the da Vinci system, especially for oncologic indications, remains to be proven in future clinical trials.

One-year follow-up after thoracoscopic sympathectomy for hyperhidrosis: outcomes and consequences.

BACKGROUND: Thoracic sympathectomy is recognized as an effective treatment for patients with severe hyperhidrosis. While good early results have been documented, continuing efficacy and patient satisfaction has not been well-defined. We reviewed our results in patients who were at least one year out from surgery. METHODS: All procedures were performed thoracoscopically using bilateral 3 mm ports and excision of a segment of the sympathetic chain by electrocautery. The level of sympathectomy depended upon clinical symptoms: T2 for face/scalp, T3 for palmar hyperhidrosis, and T4 for axillary hyperhidrosis, or a combination of levels for multiarea sweating. All patients were followed-up at least 1 year postprocedure by mail questionnaire and/or telephone. RESULTS: Two hundred twenty-two patients had undergone thoracoscopic sympathectomy for essential hyperhidrosis between Jan 1, 2002 and Nov 30, 2003, with 170 patients having at least one-year follow-up. The patients' preoperative assessment of the severity of sweating in the affected areas was compared with their one-year evaluation in order to determine the durability of the procedure. All affected areas continued to show significant improvement in sweating as compared with preoperative symptoms. Compensatory sweating was reported in 85% of our patients at one-year follow-up. Patients with a T2 lesion were significantly more likely to have severe compensatory sweating than those with other levels; 48.8% vs 16.1% (p < 0.001). Patients with levels other than T2 reported high degrees of satisfaction unrelated to their postoperative compensatory symptoms. CONCLUSIONS: Patient satisfaction and perceived effectiveness with sympathectomy for palmar or axillary hyperhidrosis remain high even one year after the procedure. Inclusion of the T2 lesion results in significantly more severe compensatory sweating and reduced satisfaction than other levels.

Thoracoscopic thymectomy mid-term results.

BACKGROUND: Results of thymectomy in patients with myasthenia gravis need to be reported in a standardized way to allow accurate comparison. METHODS: A retrospective study was conducted of 107 patients with myasthenia gravis without thymoma. Patients were followed-up for more than 12 months after thoracoscopic thymectomy and analyzed according to Myasthenia Gravis Foundation of America Recommendations for Clinical Research Standards. RESULTS: The study population was aged 8 to 60 years old and included 15 men (14%) and 92 women (86%). A right-side approach was used in 36 patients, and the remaining 71 patients had a left-side approach. Mortality was 0% and morbidity was 9.34%. The mean operative time was 90 +/- 45 minutes. The histologic diagnosis of the resected thymus was hyperplasia (78.5%), atrophy (15%), and normal status (6.5%). The mean length of hospitalization was 2.3 days (range, 2 to 6 days). The mean follow-up was 36.4 months (range, 12 to 74 months). The rate of complete stable remission was 59.5% by the end of postoperative year 6. An earlier onset age and early operation were significantly associated with complete stable remission and pharmacologic remission. A comparison of right side versus left side approach showed similarities in mean operative time, mean length of hospitalization, histopathologic results, and remission rates. CONCLUSIONS: Outcomes of the thoracoscopic approach in myasthenia gravis without thymoma were similar to those provided by open surgery, with the acknowledged benefits of minimally invasive surgery and good patient acceptance.

Impact of pleural effusion pH on the efficacy of thoracoscopic mechanical pleurodesis in patients with breast carcinoma.

OBJECTIVE: A prospective randomised study was conducted to compare the efficacy of treating malignant pleural effusions (MPE) in patients with breast carcinoma by thoracoscopic mechanical pleurodesis (TMP) as a new palliative treatment and talc pleurodesis (TP) at various pleural fluid pH levels and to determine whether at low pH values, when the success of TP is reduced, TMP is more successful. METHODS: 87 female patients with breast carcinoma and a resulting MPE resistant to systemic therapy were divided into two groups: TMP and TP groups. In the TMP group 24 patients with pH levels above 7.3 and 21 patients with pH levels below 7.3 underwent thoracoscopic parietal and visceral pleural abrasion utilising general anaesthesia. In the TP group, 22 patients with pH levels above 7.3 and 20 patients with pH levels below 7.3 were administered 5 g of sterile talc, dissolved in 100 ml of physiological solution, via a chest tube, utilising local anaesthesia. Postoperative follow-up was performed to determine a possible recurrence of MPE with periodic radiographs, the duration of chest tube drainage and hospitalisation, occurrence of complications, and perioperative mortality. The following was used for statistical analysis: t-test for odd samples, chi2 test, logistic regression, and multiple linear regression. RESULTS: TMP and TP were equally successful (92 and 91%) in patients with pH levels above 7.3. Differences occurred in patients with pH below 7.3 (81 and 55%) (P = 0.07). The lowest pH value at which TMP proved successful was 7.06, while for TP this value was 7.25. In TMP group the average duration of chest tube drainage amounted to 3.8 days and hospitalisation to 5.5 days, while in TP group it was 5.6 and 7.5 days, respectively. Differences were statistically significant (P < 0.05). 16% of easily treatable complications and no case of perioperative mortality were identified in TMP group, while 26% of complications and four cases of perioperative mortality were noted in TP group. CONCLUSIONS: TMP is a safe palliative treatment for MPE in breast carcinoma, with a minimal number of complications and a short hospital stay; it is more successful than TP in patients with pH of MPE below 7.3.

Video-assisted thoracoscopic lobectomy in infants.

OBJECTIVE: Congenital lung malformations are often discovered on routine prenatal sonography or postnatal imaging. Lesions such as congenital cystic adenomatoid malformation or pulmonary sequestration may be asymptomatic at birth, and their management is controversial. Thoracoscopy in children has been mainly used for lung biopsy and for the treatment of empyema and recurrent pneumothorax. Very few reports of more technically demanding procedures, such as lobectomy, are currently available. This report evaluates the safety and efficacy of video-assisted thoracoscopic (VATS) lobectomy in infants and small children with asymptomatic prenatally diagnosed lung lesions. METHODS: During 2004, six patients underwent VATS lobectomy without a mini-thoracotomy. Mean age was 10 months (range, 6-19 months). Preoperative diagnosis included congenital cystic adenomatoid malformation (n = 5) and an extralobar pulmonary sequestration. All patients were asymptomatic and surgery was performed electively. Three or four 3-5mm ports were used. Single lung ventilation and controlled low pressure pneumothorax were used in every case. A bipolar sealing device was the preferred mode of vessel ligation and bronchi were closed with interrupted sutures. A chest tube was left in all cases. RESULTS: All the procedures were completed thoracoscopically. Operating times ranged from 70 to 215 min (mean, 130 min). There were five lower lobe and one middle lobe resections. There were no intraoperative complications and chest tubes were left in place 1-4 days. Two patients showed postoperative hemothorax that stopped spontaneously. Hospital stay ranged from 4 to 9 days (mean, 7 days). CONCLUSIONS: VATS lobectomy in small infants is a feasible and safe technique. Decreased postoperative pain, a shorter hospital stay, and a better cosmetic result are definite advantages of this minimally invasive procedure. Long-term morbidity due to a major thoracotomy incision is avoided.

Thoracoscopic treatment of pulmonary sequestration.

OBJECTIVE: Pulmonary sequestration is a rare congenital malformation and may be the cause of recurrent infections or hemoptysis. It has been shown in case reports that resection by video-assisted thoracic surgery (VATS) is feasible despite the possible technical difficulties due to inflammatory changes, but its role has not been evaluated yet in a larger series of consecutively treated patients. METHODS: Retrospective analysis of all consecutively thoracoscopically treated patients (between January 1991 and January 2005) with pulmonary sequestration in a single center. We included 14 patients in the study who fulfilled the criteria; seven were women. Median age was 33 years (20-64 years). The following data were analyzed for all patients: major symptoms, diagnostic procedures, treatment, and outcome. Operative parameters and findings including operating time, blood loss, anatomical location of the sequestration, and feeding vessels were evaluated. RESULTS: Leading symptoms were recurrent infections (10), hemoptysis (3), and chest discomfort (1). The diagnosis was made by CT scan. Additionally, an arteriography or an angio-MRI was done in three patients and one patient, respectively. Thirteen intralobar (all lower lobes, eight on the right) and one left-sided extralobar pulmonary sequestration were resected. We performed eight lobectomies, four atypical segmentectomies, one extralobar resection, and one occlusion of the aberrant artery. One case had to be converted to a thoracotomy due to bleeding from the aberrant artery. There was no mortality. Complications included pneumonia in three cases, one hemothorax, one pneumothorax after removing the chest tube, and one wound infection. All were treated conservatively. CONCLUSION: Thoracoscopic treatment of pulmonary sequestration is feasible in experienced hands. The aberrant systemic artery can be freed and dissected safely despite the frequently occurring inflammatory changes. Conversion rate to thoracotomy is low.

Video-thoracoscopic surgical pleurodesis in the management of malignant pleural effusion: the importance of an early intervention.

Thoracentesis plays an important role in cancer patients with symptomatic effusions, although its effect is short-lived and symptoms recur in almost all patients. Early video-thoracoscopic surgical pleurodesis may provide added benefit to a group of patients with advanced cancer presenting with symptomatic malignant pleural effusion. Seventy-six patients with advanced cancer and pleural effusion due to pulmonary-pleural metastases were recruited. In 51 cases (67.1%), at least one thoracentesis was performed before admission for surgery. Preoperative staging consisted of chest radiograph, CT scan, and blood gas analysis. The mean Karnofsky performance status was about 50. Pleurodesis with talc poudrage was completely successful in all patients, with a morbidity rate of 2.6%. There was no post-operative mortality. Three patients (3.9%) underwent further thoracenteses for recurrence of pleural effusion within two months after the procedure. Early use of talc insufflated by video-thoracoscopic surgery is an effective and relatively safe method for treating pleural effusion, and preventing recurrence, in advanced cancer patients.

A prospective comparison of thoracoscopic vs open anterior instrumentation and spinal fusion for idiopathic thoracic scoliosis in children.

BACKGROUND/PURPOSE: The management of scoliosis in children has been evolving. Anterior release, diskectomy, and anterior instrumentation and spinal fusion (AISF) may be of benefit compared with a combined anterior and posterior or a posterior-only approach. Because thoracoscopic AISF (TAISF) has the potential benefit of muscle sparing, superior cosmesis, and less pain, the authors decided to prospectively compare this newer technique with open AISF (OAISF) to evaluate whether the 2 approaches were equivalent. METHODS: All children with idiopathic thoracic scoliosis undergoing AISF at a single center were prospectively examined. One hundred fifty-five children who had a minimum of 1-year follow-up were included in the study. Descriptive statistics are reported as means and SDs. Groups were compared using the independent-samples t test with Levene's test for equality of variances; a 2-tailed P value of .05 or less was considered significant. RESULTS: Open AISF was performed in 114 patients and TAISF was performed in 41; there were 126 girls and 29 boys. Mean age at surgery was similar (14 +/- 3 vs 14.3 +/- 1.5 years; P = .5), as was weight (54.2 +/- 19 vs 54.6 +/- 23 kg; P = .9). There were no differences in preoperative thoracic curves (48.5 degrees +/- 14 degrees vs 49.8 degrees +/- 7 degrees; P = .6) or in the number of vertebral levels instrumented (7.7 +/- 1.3 vs 7.6 +/- 0.7; P = .7). Operative time was shorter with OAISF (383 +/- 65 vs 508 +/- 98 minutes; P < .01), and there was less estimated blood loss (924 +/- 724 vs 1218 +/- 747 mL; P = .03). The OAISF group took longer to extubate (1.4 +/- 1.2 vs 1 +/- 0.3 days; P = .03) and had slightly greater chest tube drainage (1710 +/- 730 vs 1639 +/- 515 mL; P = .5). At the 1-year follow-up, the thoracic curves were similar (17.5 degrees +/- 8 degrees vs 15.2 degrees +/- 7.5 degrees; P = .1) and percentage correction of thoracic curves was also similar (64% vs 69%). CONCLUSIONS: Thoracoscopic AISF is safe and effective in correcting idiopathic childhood scoliosis. Correction of deformity with TAISF is equivalent to OAISF, although it takes longer and has more blood loss. However, it spares cutting muscle, uses smaller skin incisions, and appears to have superior cosmesis.

Thoracoscopic approach for congenital esophageal stenosis.

Congenital esophageal stenosis (CES) is an infrequent entity; however, many cases have been reported during the last years. Its incidence falls between 1 per 25,000 and 1 per 50,000 live births and is associated with other congenital malformations in 17% to 33% of cases (mainly esophageal atresia). Congenital esophageal stenosis is defined as an intrinsic alteration of the esophageal wall given by the presence of ectopic tracheobronchial tissue, membranous diaphragm, muscular hypertrophy, or diffuse fibrosis of the submucosa, among other causes. The therapeutic options include endoscopic dilation and resection plus anastomosis (by either laparotomy or thoracotomy, depending on the level of the stenosis). We present the case of a 1-month-old baby boy with a CES located in the distal esophagus that is associated with anophthalmia and micropenis. We treated the lesion by means of a thoracoscopic resection of the affected segment and an esophageal end-to-end anastomosis. The patient's long-term outcome was uneventful. As far as we know, this is the first report on thoracoscopic resolution of a CES.

The benefit of video-assisted thoracoscopic surgery before planned abdominal exploration in patients with suspected advanced ovarian cancer and moderate to large pleural effusions.

OBJECTIVE: To analyze the findings and impact on the management of video-assisted thoracoscopic surgery (VATS) before planned abdominal exploration in patients with suspected advanced ovarian cancer and moderate to large pleural effusions. METHODS: We reviewed the charts of all patients with suspected advanced ovarian cancer and moderate to large pleural effusions who underwent VATS from 10/01 to 7/03. VATS was performed under double lumen endotracheal anesthesia. A 2-cm chest wall incision was made in the fifth intercostal space on the side of the effusion. The thoracoscope was introduced and biopsies of suspicious lesions were performed through the single incision. After VATS, all patients had a chest tube placed through the incision, and those with malignant effusions underwent talc pleurodesis either intraoperatively or postoperatively. RESULTS: Twelve patients underwent VATS during the study period. Median operative time for VATS was 31 min (range: 20-49 min) with no complications attributable to the procedure. The median amount of pleural fluid drained was 1000 ml (range: 500-2000 ml). Solid, pleural-based tumor was found in six cases (50%), with nodules >1 cm noted in four patients (33%) and nodules <1 cm noted in two patients (17%). Of the six cases with no grossly visible pleural tumor, the pleural fluid was positive for malignant cells in two patients (17%) and negative in four patients (33%). Further initial patient management included the following: laparotomy with optimal cytoreduction, 6 (50%); diagnostic laparoscopy, 3 (25%); and no abdominal exploration, 3 (25%). Final diagnosis of primary disease site was as follows: ovary, 9 (75%); fallopian tube, 1 (8%); endometrium, 1 (8%); and lymphoma, 1 (8%). Based on the findings during VATS, laparotomy and attempted cytoreduction were avoided in four patients (33%), and the cytoreductive procedure was modified in one patient (8%). CONCLUSION: Fifty percent of patients with suspected advanced ovarian cancer and moderate to large pleural effusions who underwent VATS had solid pleural-based tumor identified, and in 33% of cases the tumor nodules were >1 cm in diameter. VATS should be considered in these cases to delineate the extent of disease, treat the effusion, and to potentially select patients for either intrathoracic cytoreduction or a neoadjuvant chemotherapy approach.

Evaluation of video-assisted thoracoscopic surgery in the diagnosis of diaphragmatic injuries.

BACKGROUND: Injury to the diaphragm from penetrating or blunt thoracoabdominal trauma is notoriously difficult to diagnose. Chest radiography, computed tomography scan, contrast studies, diagnostic peritoneal lavage, and laparoscopy are inadequate; thus, celiotomy is commonly performed in patients with suspected diaphragmatic injury. We compared the diagnostic accuracy of video-assisted thoracoscopic surgery (VATS) with that of exploratory celiotomy in the evaluation of diaphragmatic and thoracoabdominal injury. PATIENTS AND METHODS: Hemodynamically stable patients admitted to a level I trauma center with blunt or penetrating injury to the lower chest or abdomen underwent VATS and subsequent celiotomy under the same general anesthetic. Intraoperative thoracoscopic findings were blinded to the abdominal surgeons. RESULTS: Twenty-six patients were enrolled in the study over a 12-month period. Diaphragmatic injuries were identified in 8 patients (31%). Videothoracoscopy identified all eight injuries in these patients. Six of the 8 patients (75%) with diaphragmatic injuries sustained associated injury to intrathoracic or intra-abdominal organs. There was no mortality and no procedure-related morbidity. There were no missed injuries in patients who underwent VATS. CONCLUSIONS: Video-assisted thoracoscopy is a safe, expeditious, and accurate method of evaluating the diaphragm in injured patients, and is comparable in diagnostic accuracy to exploratory celiotomy.

Comparison of clinical results for unilateral and bilateral thoracoscopic lung volume reduction.

BACKGROUND: It is widely believed that bilateral thoracoscopic lung volume reduction (BTLVR) yields superior results when compared with unilateral thoracoscopic lung volume reduction (UTLVR) with regard to spirometry, functional capacity, oxygenation and quality of life results. METHODS: To address these issues, we compared the results of patients undergoing UTLVR (N = 338 patients) and BTLVR (N = 344 patients) from 1993 to 1998 at five institutions. Follow-up data were available on 671 patients (98.4%) between 6 and 12 months after surgery, and a patient self-assessment was obtained at a mean of 24 months. RESULTS: It was found that BTLVR provides superior improvement in measured postoperative percent change in FEV1 (L) (UTLVR 23.3% +/- 55.3 vs BTLVR 33% +/- 41, p = 0.04), FVC(L) (10.5% +/- 31.6 vs 20.3% +/- 34.3, p = 0.002) and RV(L) (-13% +/- -22 vs -22% +/- 17.9, p = 0.015). BTLVR also provides a slight improvement over UTLVR in patient's perception regarding improved quality of life (UTLVR 79% vs BTLVR 88%, p = 0.03) and dyspnea relief (71% vs 61%, p = 0.03). There was no difference in mean changes in PO2 (mm Hg) (UTLV 4.5 +/- 12.3 vs BTLVR 4.9 +/- 13.3, p = NS), 6-minute walk (UTLVR 26% +/- 66.1 vs BTLVR 31% +/- 59.6, p = NS) or decreased oxygen utilization (UTLVR 78% vs BTLVR 74%, p = NS). CONCLUSIONS: These data suggest that both UTLVR and BTLVR yield significant improvement, but the results of BTLVR seem to be superior with regard to spirometry, lung volumes, and quality of life.

Thoracoscopic completion thymectomy in refractory nonthymomatous myasthenia.

BACKGROUND: The aim of this study was to assess the efficacy of thoracoscopic completion thymectomy in patients with refractory nonthymomatous myasthenia. METHODS: Eight patients were operated upon after transcervical (n = 6) or transsternal (n = 2) thymectomy. The mean interval between operations was 129 months. Every patient was completely disabled despite treatment with large dosages of prednisone in combination with pyridostigmine (n = 5) or azathioprine (n = 3) and with repeated plasma exchanges. RESULTS: Gross (n = 5) or microscopic (n = 3) residual thymic tissue was found in all patients. There was no mortality, but morbidity included 2 patients with postoperative myasthenic crisis requiring reintubation and mechanical ventilation. The mean hospital stay was 4.75 days. The mean follow-up was 28.3 months. At the last follow-up, 6 patients had achieved symptomatic improvement as expressed by significant change in mean Osserman class (3.37 versus 2.12, p = 0.03), and prednisone dosage (43 versus 20 mg/d, p = 0.03). Conversely, there was no difference in dosage of pyridostigmine and azathioprine or in number of exchange cycles. CONCLUSIONS: Our results suggest that thoracoscopic completion thymectomy may be beneficial for selected patients with refractory nonthymomatous myasthenia.

Fluoroscopy-assisted thoracoscopic surgery after computed tomography-guided bronchoscopic barium marking.

BACKGROUND: Small lesions of the peripheral lung have been detected more frequently with the recent prevalence of computed tomography (CT). Identification of these lesions is indispensable for wedge resection performed by video-assisted thoracic surgery. Previous reports of marking techniques showed some failure and complications. We have developed a new marking technique and herein describe the efficacy of this technique: fluoroscopy-assisted thoracoscopic surgery after computed tomography-guided bronchoscopic barium marking. METHODS: Twenty patients underwent this procedure for 21 small peripheral pulmonary lesions approximately 10 mm in size. RESULTS: All the lesions were successfully marked and identified during fluoroscopy-assisted thoracoscopy. They were resected with sufficient margins. There were no complications related to this procedure. The pathologic examination of these 21 lesions revealed primary lung cancer in 14, atypical adenomatous hyperplasia in four, a metastatic tumor in one, and a benign tumor in two. CONCLUSIONS: This procedure is both a reliable and minimally invasive technique in thoracoscopic wedge resection for small peripheral pulmonary lesions.

Full thoracoscopic approach for surgical management of invasive pulmonary aspergillosis.

BACKGROUND: Invasive pulmonary aspergillosis (IPA) is a frequent and serious infection occurring in patients with hematologic malignancies and allogenic stem cell transplant (SCT) recipients, causing a high mortality rate. We report the use of full thoracoscopic management in 19 patients. METHODS: Nineteen patients (mean age 27 years) with diagnosed or probable IPA were operated on. Seventeen had an hematologic malignancy and 2 had a refractory aplastic anemia. Nine patients had undergone an allogenic SCT that was complicated by a graft-versus-host disease in 5 patients. In 3 patients, SCT was pending. All patients had preoperative systemic antifungal therapy for at least 2 weeks. Fifteen patients had only one lesion, whereas 4 had two lesions. Eight patients had an absolute neutrophil count less than 3,000 and 2 less than 1,000, and 9 were thrombopenic (platelet count <60,000) at the day of surgery. Wedge resections were performed in 7 patients and lobectomies were performed for the other 12. For the latter, an open approach via posterolateral thoracotomy was decided upon in only 1 patient. For the other 11 lobectomies, a mini-thoracotomy was needed in 3 cases for intraoperative difficulties. Conversion to conventional thoracotomy was necessary for 2 of these patients. In total, out of the 19 patients, 15 had a total endoscopic approach, 3 had a thoracotomy, and 1 had a video-assisted approach. RESULTS: There was no intraoperative mortality. In the group of wedge resections, no intraoperative or postoperative complication occurred. In the lobectomy group, three hemorrhages occurred during dissection of the pulmonary artery in the fissure, leading to conversion to a mini-thoracotomy in 2 patients and to a classic posterolateral thoracotomy in 1 patient. There were two minor complications: one pneumothorax and one mild pleural effusion. CONCLUSIONS: In these debilitated and immunocompromised patients, a full thoracoscopic resection of fungal infection is feasible, even for lobectomies. It allows a simpler postoperative course and minimizes sequelae.

Thoracoscopic esophagectomy combined with mediastinoscopy via the neck.

Although thoracoscopic techniques have been introduced to esophageal surgery, the identification of the left recurrent laryngeal nerve and lymph node dissection along the nerve remain quite difficult. A mediastinoscopic technique via the neck enables an excellent visual field to be created in the upper mediastinum, especially near the left recurrent laryngeal nerve. Therefore, a thoracoscopic esophagectomy combined with this technique allows mediastinal lymph nodes along the left recurrent laryngeal nerve to be easily and safely dissected.
