Video-assisted thoracoscopic lobectomy for treating lung cancer.

Our objective was to evaluate the usefulness and safety of video-assisted thoracoscopic surgery (VATS) for performing pulmonary lobectomy in 11 patients with clinical NO stage I primary non-small-cell lung cancer compared with 11 patients who underwent a conventional thoracotomy. Treatment was switched to conventional thoracotomy in three VATS patients because of the involvement of interlobar nodes or incomplete lobar fissure. None of the eight VATS patients died or experienced serious complications during 12 months of follow-up. There were no significant differences in the intraoperative blood loss, duration of operation, or duration of chest tube drainage between the VATS group and the standard lobectomy group. We conclude that although VATS lobectomy appears to be safe for use in managing patients with primary lung cancer, it does not seem to offer any advantages over standard lobectomy.

Pyoderma gangrenosum: a great marauder.

Pyoderma gangrenosum is a progressively necrotizing and ulcerative skin disease that mimics a severe bacterial infection. However, the cause is not infectious in nature and the lesions are refractory to local wound care and antibiotic therapy. The etiology of pyoderma remains unknown, although pathogenic mechanisms may involve immunologically mediated cutaneous damage. The authors report a 67-year-old woman in whom a necrotic ulcer developed at a chest tube site. Treated with local wound care and antibiotics, this lesion spread progressively to involve 15% of her body surface area. A septic clinical picture developed despite sterile cultures, and she required several operative debridements. Her disease continued to spread and finally a diagnosis of pyoderma gangrenosum was considered. Treated with systemic steroids, hyperbaric oxygen (HBO), and local wound care, she eventually underwent skin grafts.

[Treatment of advanced pleural empyema].

Despite the widespread availability of antibiotics and a declining incidence, pleural empyema still represents a serious intrathoracic disease often requiring surgical treatment for successful therapy. 104 patients with complicated pleural empyema were treated at our hospital between June 1991 and June 1997. In this retrospective study the main causes for pleural empyema were pneumonia in 41.3% and direct inoculation of the pleural space by major and minor thoracic surgery in 30.8%. Further diseases leading to an empyma of the pleural space were oesophageal perforation (11.5%), ARDS (8.7%) and hematogenous infection (7.7%). Eighty-four patients (80.8%) underwent surgery, of whom 17 patients required multiple operations. Conservative therapy with chest tube drainage and systemic application of tested antibiotics was performed in 20 patients. The overall mortality of our patients was 19.2%, but depending on the underlying disease differed considerably between 8.3% and 44.4%. Multiple operations caused by persisting empyema had a significantly higher mortality rate (58.8%) than single operations (10.5%).

"Pneumo-ptosis" in the emergency department.

The authors report the case of a 16-year-old female who presented with a left tension pneumothorax and a left Horner's syndrome. Chest tube thoracostomy performed to relieve the tension pneumothorax also resulted in the immediate resolution of the patient's ptosis and miosis. The probable mechanism for the patient's focal neurologic signs was traction upon the cervical sympathetic chain secondary to the mediastinal shift of the tension pneumothorax. This case demonstrates that unequal pupils in the presence of a pneumothorax could represent Horner's syndrome.

The evidence on the effectiveness of management for malignant pleural effusion: a systematic review.

The aim of this study was to review systematically the available evidence on pleurodesis for malignant effusion, focusing on the choice of the agents, route of delivery and other strategies to improve outcomes. Four electronic databases (MEDLINE, EMBASE, Web of Science and Cochrane Controlled Trials Register) were searched, reference lists checked and letters requesting details of unpublished trials and data sent to authors of previous trials. Studies of malignant pleural effusion in humans were selected with no language restrictions applied. Criteria for randomised clinical trial (RCT) eligibility were random allocation of patients and non-concurrent use of another experimental medication or device. Methodological quality evaluation of the trials was based on randomisation, blinding, allocation concealment and intention to treat analysis. A random effect model was used to combine the relative risk estimates of the treatment effects whenever pooling for an overall effect was considered appropriate. Forty-six RCTs with a total of 2053 patients with malignant pleural effusions were reviewed for effectiveness of pleurodesis. Talc tended to be associated with fewer recurrences when compared to bleomycin (RR, 0.64; 95% CI, 0.34-1.20) and, with more uncertainty, to tetracycline (RR, 0.50; 95% CI, 0.06-4.42). Tetracycline (or doxycycline) was not superior to bleomycin (RR, 0.92; 95% CI, 0.61-1.38). When compared with bedside talc slurry, thoracoscopic talc insufflation was associated with a reduction in recurrence (RR, 0.21; 95% CI, 0.05-0.93). Strategies such as rolling the patient after instillation of the sclerosing agent, protracted drainage of the effusion and use of larger chest tubes were not found to have any substantial advantages. Talc appears to be effective and should be the agent of choice for pleurodesis. Thoracoscopic talc insufflation is associated with fewer recurrences of effusions compared with bedside talc slurry, but this is based on two small studies. Where thoracoscopy is unavailable bedside talc pleurodesis has a high success rate and is the next best option.

[Pulmonary lymphangiectasis with spontaneous chylothorax in Noonan syndrome].

We report a case of Noonan syndrome associated with pulmonary stenosis and major lymphedema of the lower extremities. At the age of 15 yr spontaneous chylothorax with increasing dyspnea occurred> Chest-x-ray demonstrated increased interstitial markings restricted to the right lower lobe representing pulmonary lymphangiectasia. The chylothorax did not respond to repeated thoracocentesis and medium-chain-triglyceride diet. When a chest tube was inserted and total parenteral nutrition was supplied, the chylous effusion decreased within 32 days. The patient is still on diet and asymptomatic effusion remained during 12 months follow up. In conclusion, pulmonary lympgangiectasia should be considered in patients with Noonan syndrome and an abnormal interstitial pulmonary pattern similar to pulmonary congestion (without any hemodynamic abnormalities). In case of pleural effusion, chylothorax should be considered.

Role of video-assisted thoracic surgery for the treatment of myasthenia gravis: extended thymectomy by median sternotomy versus the thoracoscopic approach with sternal lifting.

The role of video-assisted thoracic surgery (VATS) thymectomy is still being studied, and many surgeons remain skeptical of the value of this recent option. We made a retrospective evaluation to ascertain whether VATS-extended thymectomy is as reliable as standard median sternotomy in the treatment of myasthenia gravis (MG) and whether the endoscopic procedure presents any advantages for patients. Eighteen consecutive patients requiring extended thymectomy for MG were treated between April 1997 and September 2003 at our hospital. Nine patients received VATS-extended thymectomy, and the remaining nine patients received standard extended thymectomy by sternotomy. In the VATS group, the anterior mediastinal space was well visualized by sternal lifting. The mean operative time was 268.3 +/- 51.1 minutes in the VATS group and 177.3 +/- 92.5 minutes in the sternotomy group. Operative time was significant longer in the VATS group than in the sternotomy group (P < 0.05). The mean operative bleeding was 68.6 +/- 47.8 ml in the VATS group and 154.1 +/- 109.0 ml in the sternotomy group. Operative bleeding was significantly less in the VATS group than in the sternotomy group (P < 0.05). There was no significant difference between the two groups with regard to postoperative duration of chest tube or the level of serum C-reactive protein on the first operative day. There was a downward trend in nicotinic acetylcholine receptors antibody levels after thymectomy compared with before thymectomy in both groups. VATS thymectomy should be considered a valid alternative to the established approaches aimed at achieving a "curative thymectomy" in patients with MG.

[Pulmonary resections and prolonged air leak].

BACKGROUND: The aim of our study was to determine risk factors for prolonged air leak after pulmonary resections. METHODS AND RESULTS: Two hundred and five patients were operated at our department between January 2003 and March 2004. Prolonged air leak (PAL) was defined as an air leak lasting 7 days or more of postoperative chest tube drainage. PAL occurred in 17 (8.3%) patients and it lasted 10.1+/-3.5 days. COPD remained the only variable predicted for PAL (p<0.05). This complication significantly prolongs the length of hospitalization (p<0.01). CONCLUSIONS: COPD patients have significantly higher risk for PAL following pulmonary resection. Intraoperative prevention of the air leak requires meticulous surgical technique, stapler use and application of pericardial bovine strips.

Unilateral pulmonary oedema due to lung re-expansion following pleurocentesis for spontaneous pneumothorax. The role of non-invasive continuous positive airway pressure ventilation.

Re-expansion pulmonary oedema represents a rare complication of treatment of spontaneous pneumothorax with only a few cases documented in the current literature. We present the case of a 47-year-old male who presented a right-sided spontaneous pneumothorax and developed respiratory failure after chest tube drainage. The diagnosis of re-expansion pulmonary oedema was made and he was successfully treated with non-invasive continuous positive airway pressure ventilation. Since pathogenesis of re-expansion unilateral pulmonary oedema differs significantly from that of cardiogenic pulmonary oedema, the role of non-invasive continuous positive airway pressure ventilation is discussed as an additional therapeutic option.

Is surgical closure of patent ductus arteriosus a safe procedure in premature infants?

Despite indomethacin therapy, many premature infants require surgical closure of their patent ductus arteriosus (PDA). Between January 1985 and December 1997, 176 premature infants underwent surgical closure of PDA by vascular clip after failure of medical treatment. The median gestational age and birth weight were 26 weeks (range 23-36 weeks) and 847.5 g (range 400-2300 g), respectively. The median age at diagnosis and at surgery was 4 days (range, 1-37) and 21 days (range, 4-60) respectively. The median weight at surgery was 982.5 g (range 475-2740 g). Of these infants, 168 (95%) were intubated prior to surgery and the median time to extubation was 21 days (range 1-273 days). There were no operative deaths but 11 infants (6.4%) died from complications of prematurity (sepsis, bronchopulmonary dysplasia and pulmonary hemorrhage). The frequency of chest tube insertion at surgery decreased from 41.7% to 10% between the 1985-88 and 1996-97 periods (P<0.01). Three infants (1.7%) developed vocal cord paralysis directly related to the position of the vascular clip. Echocardiography confirmed PDA closure in 43 infants (24.4%) while the remaining 133 had no clinical signs of PDA. Surgical closure of PDA by vascular clip carries a very low morbidity in premature infants.

Pleuropulmonary morbidity: internal thoracic artery versus saphenous vein graft.

Although use of the internal thoracic artery (ITA) for coronary artery bypass grafting results in superior graft patency and improved patient survival, our initial clinical observations suggested an increased incidence of pleuropulmonary morbidity with its use. One hundred consecutive patients with left ITA grafts were studied prospectively and compared with a consecutive retrospective group of 100 patients undergoing coronary artery bypass grafting with saphenous vein grafts only. Preoperative, postoperative day (POD) 2, POD 6, and postoperative week 8 chest roentgenograms were analyzed for atelectasis and effusion. Postoperative left lower lobe atelectasis was common in both groups on both POD 2 (saphenous vein, 43%, versus ITA, 53%; not significant) and POD 6 (saphenous vein, 40%, versus ITA, 41%; not significant). There was a significantly higher incidence of pleural effusion on POD 6 in the ITA group (84% versus 47%; p less than 0.05) but most of these were small. There was more chest tube drainage (1,413 versus 1,028 mL; p less than 0.01) and a greater need for secondary thoracostomy or thoracentesis (4% versus 0%) in the ITA group. The left pleural space was opened in 67 of the 100 ITA patients but pleurotomy did not appear to influence postoperative morbidity. We conclude that use of the internal thoracic artery for coronary artery bypass grafting results in a small but significant increase in pleuropulmonary morbidity.

Video-assisted thoracoscopic surgical excision of cystic lung disease in children.

PURPOSE: Video-assisted thoracoscopic surgical (VATS) technique for resection of cystic lung disease (CLD) may offer some advantages when compared with thoracotomy in children. METHODS: From September 1999 to August 2004, 6 pediatric patients underwent VATS for CLD. Patients were chosen for VATS based upon surgeon's choice. Data are expressed as mean +/- SD. The Children's Healthcare of Atlanta institutional review board approved this study. RESULTS: The types of lesions included congenital cystic adenomatoid malformations (n = 1), extrapulmonary sequestrations (n = 3), congenital lobar emphysema (n = 1), and bronchogenic cyst (n = 1). The extent of resection included lobectomy (n = 2) and excision (n = 4). Age and weight were 11.8 +/- 18 months (range 6 days to 4 years) and 7.5 +/- 3.6 (range 4.0-14.0) kg, respectively. Operating time was 103 +/- 70 (range 38-223) minutes. Chest tube duration was 1.2 +/- 0.8 (range 0-2) days. Morphine use on the first postoperative day was 0.2 +/- 0.3(range 0.05-0.20) mg/kg. Length of stay was 2.5 +/- 1.9 (range 1-6) days. There were no conversions to thoracotomy and no complications. CONCLUSION: VATS technique appears to be a safe and effective technique in managing CLD in children of all ages. More patients, however, need to be studied.

Medical management of parapneumonic pleural disease.

Considerable heterogeneity exists in the management of parapneumonic pleural disease. A randomized controlled trial (RCT) demonstrated the effectiveness of small-catheter drainage with fibrinolysis, but surgical devotees suggest this may only be applicable to "early" cases. We examined evidence-based medical management in "all-comers." We performed a retrospective database analysis of the management of all children with complex pleural effusion admitted to the John Radcliffe Hospital over the 7-year period 1996-2003. One hundred and ten children were admitted. Ten were excluded as they were part of a multicenter RCT and had received intrapleural saline instead of urokinase. Of the remaining 100, 51 were female and 49 male. Median age on admission was 5.8 years (range, 0.3-16.5). Symptoms preadmission averaged 11 days, with December the most common month for presentation. Ninety-six underwent chest ultrasound, confirming an effusion in all, described as loculated/septated (68) or echogenic (11). In 17 cases, no specific comment was made regarding the nature of the fluid seen on ultrasound. Ninety-five had subsequent chest tube drainage and then received intrapleural fibrinolysis with urokinase. An etiological organism was identified in 21 cases (21%) (Streptococcus pneumoniae in 10, group A Streptococcus in 5, Staphylococcus aureus in 4, Haemophilus influenzae in 1, and coliform in 1). In a further 9 cases (9%), Gram-positive organisms were seen on pleural fluid microscopy, but did not grow on culture. Two (2%) required surgery due to the persistence of symptoms and an inadequate response to medical management. Median duration of admission was 7 days (range, 2-21 days); median duration of stay from intervention was 5 days (range, 2-19 days). At median follow-up of 8 weeks (range, 3-20 weeks), all children were symptom-free, with minimal pleural thickening on chest X-ray. In conclusion, antibiotic therapy with chest drain insertion and intrapleural urokinase is effective in treating complex parapneumonic effusion and is associated with a good long-term outcome.

One hundred and sixty-three consecutive video thoracoscopic procedures: the Hong Kong experience.

Video-assisted thoracoscopy (VAT) offers a new approach to the diagnosis and treatment of many thoracic conditions. From September 1992 to August 1993, a total of 163 VAT procedures were successfully performed on 108 patients (87 male, 21 female; age range from 12 to 77) which consisted of 42 bleb eliminations and 64 mechanical pleurodesis for spontaneous pneumothorax, 11 wedge resections for pulmonary nodules, three wedge biopsies for diffuse pulmonary infiltrate, four thoracic sympathectomies, resections of two mediastinal masses, three pericardial windows, 10 guided pleural biopsies for undiagnosed effusions, six guided drainage of empyema and haemothorax, 16 staging of intrathoracic tumours and two explorations for penetrating thoracic trauma. There was no procedure-related mortality. Complications included one recurrence for spontaneous pneumothorax, one re-exploration for bleeding (also by VAT approach), one wound infection, and six persistent air leaks for more than 10 days. The median duration of postoperative chest tube drainage was 2 days and the median hospital stay was 4 days. It was concluded that VAT is a safe and effective approach in thoracic surgery and with further refinement in instrumentation even more procedures will be technically feasible. The long-term results of VAT are being awaited in order to define its true merits in thoracic surgery.

Use of the argon beam electrocoagulator for performing pulmonary wedge resections.

The argon beam electrocoagulator (ABC) is a new form of electrocautery that is thought to be more effective than standard electrocautery. It has been used primarily in procedures associated with major blood loss such as liver transplantation and laparotomy for trauma. It has not been used in thoracic operations. We evaluated the safety and efficacy of the argon beam electrocoagulator for performing pulmonary wedge resections in an animal model by comparing it with standard electrocautery and suture closure. Variables used to compare the three methods of resection included perioperative blood loss, duration of chest tube air leak, and depth of necrosis and severity of inflammatory reaction in the lung at ten days and 3 weeks after resection. The argon beam electrocoagulator was as effective as standard electrocautery and suture closure in controlling air leaks, and caused less acute tissue injury than standard electrocautery. The argon beam electrocoagulator provides a safe and effective method for performing small pulmonary wedge resections, and should be evaluated in the clinical setting for this purpose.

Use of the Heimlich valve to shorten hospital stay after lung reduction surgery for emphysema.

BACKGROUND: Prolonged air leak is the major complication after lung reduction surgery for emphysema and the major determinant of hospital length of stay. METHODS: Twenty-five of 107 patients (24%) (mean age, 66 years) with an average forced expiratory volume in 1 second of 0.55 L experienced a prolonged air leak (>5 days) after lung reduction surgery. These persistent air leaks were treated by replacing the chest drainage system with Heimlich valves to facilitate earlier hospital discharge even though 64% of the patients had apical air spaces that measured 1 to 7 cm. RESULTS: These patients had a mean postoperative stay of 9.1 days. Chest tubes were then removed an average of 7.7 days later. All apical air spaces resolved, and there were no deaths, empyemas, or pneumonias. CONCLUSIONS: In conclusion, the use of the Heimlich valve after operation for emphysema was associated with minimal morbidity and shortened the mean hospital stay for patients with prolonged air leaks by 46%. This study demonstrates an important concept in the postoperative management of these patients--do not use suction on severely emphysematous lung.

Comparison of the effectiveness of some pleural sclerosing agents used for control of effusions in malignant pleural mesothelioma: a review of 117 cases.

BACKGROUND AND OBJECTIVES: Management of malignant pleural mesothelioma (MPM) has been an important clinical issue regardless of the treatment modality employed. We aimed to investigate the efficacy of oxytetracycline (OT), Corynebacterium parvum (CP), and nitrogen mustard (NM) in the management of pleural effusion associated with MPM. METHODS: One hundred and seventeen patients who had stage-2 MPM or over according to the Butchart staging system and unilateral or bilateral pleural effusion took part in the study. The patients received either OT (35 mg/kg), CP (7 mg), or NM (0.4 mg/kg) through a chest tube for pleurodesis. The association between several clinical parameters and patient survival was also investigated. RESULTS: OT was applied to 59, CP to 29 and NM to 29 cases. A statistical analysis of the results obtained by these agents have demonstrated that OT (30 days, 81%; 90 days, 76.2%) and CP (30 days, 86.2%; 90 days, 79.3%) led to a significantly higher rate of successful pleurodesis as compared to NM (30 days, 48.2%; 90 days, 41.3%; p <0.05). Although the procedure was generally well tolerated by the patients, the NM-treated group experienced significantly more nausea-vomiting (46.1%) and hypotension (35.8%) compared to patients who received OT (nausea-vomiting and hypotension 4.3%; p < 0.001) and CP (nausea-vomiting and hypotension 5.1%; p < 0.001). Furthermore, we found that thrombocytosis, chest pain and weight loss were significantly associated with poor prognosis, whereas epithelial type had a positive effect on survival. CONCLUSION: These results suggest that OT and CP may be used as effective sclerosing agents for pleurodesis in the control of pleural effusions associated with MPM, without major side effects.

Transhiatal esophagectomy for carcinoma of the esophagus and cardia. Experience with 160 cases.

We reviewed our experience from 1979 to 1990 with 160 cases of transhiatal esophagectomy for carcinoma of the lower esophagus and cardia to evaluate trends in patient selection, management, and outcome. Patients treated in the past 6 years (n = 110) and those treated before 1985 (n = 50) were similar in terms of age and sex distribution, medical history, and weight loss. The majority of tumors seen were adenocarcinoma, with patients in the latter group having significantly lower stages. Significant decreases in anesthetic time, units of blood transfusions, chest tube insertions, length of postoperative ventilation, incidence of postoperative pneumonia, and length of hospital stay were seen during the past 6 years. Wound infections increased significantly during the same period. The decrease in the 30-day mortality rate from 6% to 0.9% was not significant. Survival rates did not differ between groups, with overall rates of 62%, 40%, and 21% at 1, 2, and 5 years, respectively.
