[Treatment of achalasia of the cardia using thoracoscopic esophago-myotomy].

We performed left thoracoscopic esophagomyotomy in four patients suffering from achalasia cardiac. In one patients the esophageal mucosa was opened during the myotomy. This was sutured through thoracoscopy and the per os feeding of the patient started on the 8th postoperative day, while in the other three patients this was done on the 2nd postoperative day. The mean emission of the patients was on the 6th postoperative day. Comparison of the status before and 6 weeks following the operation was done on the basis of results of different examinations i. e. x-ray, esophago-gastroscopy, manometry, pH-metry, isotope test. The favourable results of the operations were declared as all examinations revealed marked improvement and all patients have better swallow function and 6-9 kg increase in body weight.

Unilateral left-sided thoracoscopic sympathectomy for visceral pain control: a pilot study.

OBJECTIVE: To examine the effect of unilateral left sided thoracoscopic denervation of the upper gastrointestinal tract for treatment of chronic pain. DESIGN: Prospective study. SETTING: University hospital, Sweden. SUBJECTS: Patients with intractable upper abdominal pain. Nine patients were treated who had the following diagnosis: pancreatic carcinoma (4), duodenal carcinoma (n = 1), chronic pancreatitis (3), and portal vein thrombosis (n = 1). INTERVENTIONS: Left-sided thoracoscopy with the patient anaesthetised using double-lumen endotracheal intubation that allowed ventilation of the right lung only. The sympathetic chain and splanchnic branches were divided from level IV to X-XI. MAIN OUTCOME MEASURES: Severity of pain assessed by a visual analogue scale and mean consumption of analgesic drugs. RESULTS: All patients reported substantial relief of pain postoperatively when they were studied during a mean follow-up period of 3 months. However, two patients (1 with pancreatic carcinoma and 1 with portal vein thrombosis) had recurrent pain after 3 months. CONCLUSION: Unilateral thoracoscopic sympathectomy induces adequate and lasting relief of pain caused by benign as well as malignant diseases originating from the pancreatic region.

[Chylothorax as a complication of sarcoidosis].

This case report features a male patient of 45 years of age presenting with a right sided moderately compressive pleural effusion, that was clearly identified as chylothorax on thoracocentesis. Sarcoidosis with systemic involvement had already been diagnosed in 1995 by a parotid gland biopsy. Thoracoscopy revealed multiple discrete nodules parietally besides a number of more extensive yellowish lesions resembling malignant lymphoma. However visualization of a thoracic duct leakage was not possible. Histologically the biopsies taken represented exclusively non-caseating sarcoidosistype granulomas. Complete and permanent remission of the chylothorax was achieved within only ten days following talcum pleurodesis, alimentary measures and induction of systemic steroid therapy. The etiological classification of this extremely rare complication appears very clear. Pathogenetic and differential therapeutic aspects are discussed against the background of a review of the literature.

The role of video-assisted thoracic surgery in the diagnosis and treatment of indeterminate pulmonary lesion.

Patients with indeterminate pulmonary lesions usually require a definite diagnosis for proper management. The conventional diagnostic procedures such as bronchoscopy and transthoracic needle biopsy sometimes fail to obtain a decisive answer, thus a more aggressive diagnostic procedure will be needed. Video-assisted thoracic surgery (VATS) has provided an alternative for open thoracotomy for definite diagnosis in these conditions. Thirty-three patients with indeterminate pulmonary lesions received VATS in National Taiwan University Hospital. Of these patients, twenty-eight manifested with coin lesion and five had diffuse pulmonary infiltration before operation. Traditional diagnostic procedures, i.e. bronchoscopy or transthoracic needle biopsy, could not give a definite diagnosis for these patients. A definite diagnosis was obtained after thoracoscopy in all of these patients. The mean operation time was 129 minutes (range, 180 to 45 minutes). The mean duration of chest tube drainage was 4.1 days (range, 1 to 7 days). The mean postoperative hospital stay of elective surgery without subsequent chemotherapy or radiotherapy was 9.5 days (range, 5 to 14 days). The patients received 2.4 times parental narcotics injection for analgesia on average (range, 0 to 6 times). There is no operation-related death in this series. Three patients had prolonged air leak with seven days of chest tube drainage. Two patients, with CMV and chronic interstitial pneumonia, have mortality from their underlying disease later. VATS is a safe and effective procedure not only for diagnosis, but also for treatment in the management of indeterminate pulmonary lesions.

Major thoracoscopic operations: pulmonary resection and mediastinal mass excision.

After the great success of laparoscopy in the field of abdominal surgery, the mini-invasive approach has opened interesting new possibilities in the field of thoracic surgery too. At present, in many centres, thoracoscopy is the surgical approach of choice for the treatment of recurrent pneumothorax, giant bullous lung disease, peripheral benign lesions. In very few centres a new phase is now starting, having the objective of verifying the validity of more complex thoracoscopic surgical operations. The authors describe their experience in performing major thoracoscopic operations such as excision of mediastinal masses and major pulmonary resections. The series includes 36 patients submitted to thoracoscopic excision of mediastinal masses and 113 patients submitted to video-thoracoscopic major pulmonary resections. Every kind of mediastinal lesion as well as every kind of major pulmonary resection was performed; the evidence of no intra-operative deaths confirms the possibility of a useful employment of the mini-invasive approach in this kind of surgery.

[Video-assisted coronary artery bypass].

The benefits of the internal mammary artery (IMA), as a graft, particularly for the left anterior descending (LAD) coronary artery disease, have been demonstrated. Coronary artery bypass grafting (CABG) without cardiopulmonary bypass (CPB) is now an accepted technique of myocardial revascularization. Thoracoscopy and a minimal thoracotomy have been applied to cardiac surgery, however its use has not been well defined; in our approach, we harvested the left IMA thoracoscopically. Following this the left IMA-LAD coronary artery anastomosis was fashioned, by means of a left small anterior thoracotomy on the beating heart without CPB. A double lumen endotracheal tube was used so the lung could be collapsed. Three left lateral chest ports of 1 cm were made, and the thoracoscope was placed through the initial port, permitting inspection of the thorax. The other ports were used for IMA dissection, using endoscopic instruments (electrocautery, grasping, forceps,...), the side branches were controlled by either cautery or endoscopic clips. When it was possible, the anterior port was extended doing a small left anterior thoracotomy, the pericardium was exposed, the IMA was divided and exteriorized through the thoracotomy. After coronary artery control, the bypass graft was carried out on the beating heart without CPB, in 26 patients. From september 1995 to july 1996, we have operated on 30 patients using this technique. We believe that with increasing operator experience, this minimally invasive approach will have a major impact on the management of the coronary artery disease patients, with a faster recovery, shorter hospitalization, and certainly less cost.

[A case of non-smoking female with peripheral small lung squamous cell carcinoma discovered after operation of spontaneous pneumothorax].

We have experienced a lung cancer patient discovered after operation of pneumothorax by chance. The patient was 44-year-old female who had been followed up for right pneumothorax in menstruation. She got pneumothorax in menstruation recurrently complained of chest pain. Chest X-p revealed right pneumothorax. We never discovered views of catamenial pneumothorax by thoracoscopy. Partial resection of hypertrophic pleura of right S1 was performed by video assist thoracoscopic surgery. Histological diagnosis was bulla formation with a tiny focus of squamous cell carcinoma in situ. In addition, right upper lobectomy and lymph node dissection were performed. Metastasis was not recognized any lymph node. No recurrence has been observed for 17 months.

The diverse potential of thoracoscopic assisted surgery.

Thoracoscopy has been a part of thoracic surgical practice for many years. The introduction of the camera chip and newer instrumentation has awakened a new interest in this technique and led to the development of video-assisted thoracic surgery (VATS). One hundred and seventy consecutive procedures performed on 158 patients are reviewed. Video-assisted techniques have proven useful in a broad spectrum of thoracic surgical procedures both diagnostic (n = 90) and therapeutic (n = 80). Hospital mortality was 1.3%. Conversion to formal thoracotomy was required in 2.5%, and re-exploration for bleeding in 0.6%. The technique was safe and the incidence of complications acceptable. VATS was particularly helpful in diagnosing "indeterminate" pulmonary nodules (sensitivity of 95%), interstitial lung disease (histological diagnosis in all), anterior mediastinal masses and post transplant pneumonitis. VATS may now be the surgical treatment of choice in those with spontaneous pneumothorax, and it also proved useful in a variety of benign disorders. Its role in the management of empyaema is limited with a 57% conversion rate. While pulmonary resections are feasible, its role in the therapeutic management of malignancy is questioned. Further studies are required to define the precise role of VATS in thoracic surgery.

Nursing care of patients undergoing thoracoscopic minimally invasive bypass grafting.

Recent efforts in cardiac surgery to decrease cost, length of hospitalization, and morbidity without compromising care or outcomes include a method of treatment of coronary heart disease called minimally invasive coronary artery bypass grafting. This article describes the use of thoracoscopy without sternotomy, cardiopulmonary bypass, or cardioplegic arrest for grafting of the left anterior descending branch of the coronary artery with the left internal mammary artery. Preliminary information supports the concept that thoracoscopic minimally invasive bypass grafting is a less costly and less invasive procedure for patients with disease of the left anterior descending branch of the coronary artery.

[Video-assisted bedside pleuroscopy under local anesthesia: use of a rigid cystoureteroscope in patients with undiagnosed pleural effusion].

Up to 20% of pleural effusions remain undiagnosed despite history-taking, physical examination, thoracentesis, and percutaneous closed pleural biopsy. The next diagnostic procedure used is often thoracoscopy under general anesthesia in an operating room. We report a technique for beside pleuroscopy and pleural biopsy that can be done without assistance of surgeons. We performed video-assisted pleuroscopy with a rigid cysto-ureteroscope in seven patients with pleural effusion that remained undiagnosed despite extensive clinical evaluation. A sterile 19.8 Fr. rigid cysto-ureteroscope was placed into the pleural space under local anesthesia. Pneumothorax was induced to enhance visualization of the surfaces. Forceps-biopsy specimens were taken of suspicious lesions on the parietal pleural. In three patients the pleural surface appeared smooth and in two the parietal pleural surface was studded. A localized coin-like lesion was seen in one patient, and extensive fibrinogenic adhesions and diffuse opacity of the parietal pleura was seen in another. Using this bedside procedure, we diagnosed pleural tuberculosis in three patients and pleural metastases of adenocarcinoma in one. When done under local anesthesia with a rigid cyst-ureteroscopy, video-assisted pleuroscopy can be a safe and useful diagnostic aid in patients with undiagnosed pleural effusion.

[Diagnosis of pleurisy].

Diagnosis of pleural effusion, suggested by chest pain or dyspnea, is assessed by physical examination, chest X-ray sometimes completed by other imaging techniques, and mainly by thoracentesis. Thoracentesis is mandatory for the diagnostic of pleural effusion as three diagnosis are associated with an emergency treatment: pulmonary embolism; hemothorax; empyema. If the fluid is a transudate, no further invasive studies are necessary. If the cause of pleural exsudat cannot be established by a careful history, physical examination and fluid analysis, generally closed pleural biopsy should be done, followed, in absence of an established diagnosis, by thoracoscopy. At this time, less than 10% of the cases remain without explanation, leading to a careful follow-up of patients since a carcinomatous lesion may develop in 1/3 of them.

[Thoracoscopic surgery for the giant bulla complicating pulmonary eosinophilic granuloma: a case report].

We report a case of pulmonary eosinophilic granuloma (PEG) accompanied with a giant bulla successfully operated with a thoracoscopy. A 24-year-old female had been suffering from recurrent bilateral pneumothoraces with multiple bullae since February 1993. She was diagnosed as PEG with an open lung biopsy in July 1994. Repetitive pleurodesis were efficacious against the pneumothoraces. However, a bulla in the left upper lobe were growing with her respiratory function having worsened to bed rest. In May 1995, thoracoscopic surgery were performed to extinguish the bulla. Trocars were directly introduced into the lumen of the bulla. Ligation of the three communicating bronchial branches and tube drainage made the bulla disappear immediately. The patient had been well for one and a half year postoperatively.

[Thoracoscopic approach in pulmonary nodules: a prospective evaluation of a series of 120 patients].

UNLABELLED: More and more pulmonary nodules are currently approached via thoracoscopy. We have evaluated the results and the morbidity of a consecutive series of 120 patients operated on by a single surgeon. PATIENTS AND METHODS: Hundred twenty-two nodules have been approached thoracoscopically in 120 patients. The average size of these nodules was 16 mm (3-30 mm). A pre-operative localisation technique has been used in 61 patients (50%). The procedures were as follows: biopsy (6 cases), wedge-resection (110 cases). A video-assisted lobectomy has been performed in 26 cases. RESULTS: The mortality rate was 0.08% (One case of ARDS in the post-operative course of a video-assisted lobectomy). Intra-operative morbidity rate was 1.6% (2 cases of haemorrhage requiring a thoracotomy and the post-operative morbidity rate was 5%. Six procedures were converted to thoracotomy 55%). The nodules have been localised in all cases but 2 (1.6%). The mean post-operative stay was 4.6 days in the whole series and 3.2 days in the series of patients with a simple biopsy or wedge-resection. COMMENT: The morbidity rate of thoracoscopic resection of lung nodules is very low and decreases with surgeon's experience. Experience allows one not to use a localisation technique in many cases, but the later remains helpful in small size nodules. It allows for a safe, rapid and accurate procedure to be performed. The need for a mini-thoracotomy is very rare. Mastering the techniques of radiological localisation techniques, thoracoscopic biopsy and wedge resection as wall as video-assisted lobectomies should make it possible for thoracoscopic resection of lung nodules to fulfil the criteria of a minimally invasive operation.

[Video-assisted thoracic surgery (VATS) for intrathoracic tumors].

Owing to the advent of new thoracoscopic instrument and technique, video-assisted thoracic surgery (VATS) has become a new standard in the resection of intrathoracic tumors. Thoracoscopy can be used as both exploratory and therapeutic means. Included as the indication for VATS resection are as follows: benign and malignant lung tumors such as lung cancer, metastatic lung tumor, and etc., benign mediastinal tumors, and benign pleural tumors. Still the indication for VATS resection for malignant disease, especially for lung cancer, is not defined. Further improvement is required in the resectional technique and instruments.

Video endoscopic truncal vagotomies without gastric drainage.

The authors report 32 patients with chronic duodenal ulcer treated by bilateral truncal vagotomy (BTV) performed via laparoscopy or thoracoscopy. All cases were resistant to medical treatment and chosen with selective indication regarding endoscopic/radiologic and laboratory examination for absence of pyloric obstruction and presence of hyperacidity. Only one patient had partial pyloric stenosis preoperatively due to chronic duodenal ulcer. No drainage procedure was used after BTV, and an endoscopic pyloric balloon dilatation (PBD) was performed at the same time as vagotomy for 20 cases; 12 patients were followed without dilatation as a prospective trial. Semiliquid diet and promotility medication were started 24 h after surgery. All patients tolerated pure truncal vagotomy without any problem, except for two patients: one in whom open drainage procedure was required and one in whom PBD was performed. Basal acid output and peak acid output were measured the day before and 1 week after the operation. A mean decrease of hyperacidity was found: 70.6% for basal and 79.5% for peak acid output. Four patients suffered from moderate symptoms of diarrhea occurring intermittently and responded to medical treatment or recovered spontaneously. Median hospital stay was 4.8 days (range 3-10 days). Endoscopic control performed for 28 patients 2 and 6 months after the operation showed healing of the ulcer. But the patient who had partial pyloric stenosis and was operated on with BTV and PBD required an open drainage procedure (Jaboulay gastrojejunostomy) in spite of repeated PBD. There was no other gastropyloric outlet obstruction in this preliminary study with mean follow-up of 22 months (range 6-42 months).

[Taking advantage of thoracoscopic techniques for diagnosis and treatment of thoracic diseases].

The authors report their experience in VATS technique employed in the diagnosis and treatment of pleural and mediastinal diseases and lung tumors. Between 1992 and 1996, 50 thoracoscopic procedures were carried out in 48 patients. The following operations were performed: six thoracic sympathectomies, two cases of closing bronchial stump fistulas, six cases of successfully treated spontaneous pneumothorax. In eight cases (16.3%) it was necessary to convert this procedure into thoracotomy because of pleural adhesions. The diagnostic thoracoscopies (35 cases) included: mediastinal and lung tumor biopsies, taking up samples of pleural exudate. There were no complications connected with these procedures. We consider thoracoscopic technique to be a suitable method for the diagnosis and treatment of mediastinal and pleural lesions.

[The diagnostic value of thoracoscopic examinations in tuberculous pleurisy].

We evaluated the diagnostic value of thoracoscopic examinations in eleven patients who had pleural effusion and were diagnosed as tuberculous pleurisy. The characteristic white or yellowish-white micronodules were observed by thoracoscopy in eight patients and all their biopsied tissue were compatible with tuberculosis. We had some cases which were not determined as tuberculous pleurisy from bacteriological examinations and were determined only from the thoracoscopic findings.

[The role of surgery in tuberculosis in children].

Despite increasingly rigorous preventive measures which have limited the number of cases in France, the number of children undergoing surgery for tuberculosis has remained unchanged. Over the last ten years we operated on 40 children in our pediatric unit. In 10 cases, surgery was indicated for diagnosis, in 19 cases surgery was required in an emergency situation during treatment and in 11 the operation was performed at the stage of sequellae. The type of surgery depended on the clinical situation. Thoracoscopy was used for surgical diagnosis and to empty caseous nodes in the lateral tracheal chain but was generally impossible at the sequellae stage.
