Combined right atrial resection for lung cancer that developed intractable atrial flutter

We have encountered a patient with primary lung cancer with invasion into the right atrial wall with N2 disease. Complete resection of the tumor combined with the right atrial wall was achieved under cardiopulmonary bypass after induction chemoradiotherapy. Pathological results confirmed ypT0N0M0. Post-operatively, atrial flutter resistant to rate control with calcium-antagonists and β-blockers was treated with catheter ablation of the atrioventricular node.

Bilateral sleeve lobectomy for metachronous multiple primary lung cancer

In a patient with metachronous multiple primary lung cancer, bilateral lobectomy was performed, using bronchoplastic procedures. This case may be one of very few such cases reported in the literature. A 56-year-old man with squamous cell carcinoma was surgically treated for lung cancer. At the first operation, right upper lobectomy with wedge resection of the right main bronchus was performed, as the tumor occupied the orifice of the right main bronchus. Six months later, re-operation for stricture at the anastomotic line was done because of granulation. By means of sleeve resection of the strictured right main bronchus, the airway was reconstructed. The patient remained well for five years, then a similar cancer at the orifice of the left lower lobe and bulging into the left main bronchus became evident. Left lower sleeve lobectomy was done for the second primary cancer. The postoperative course was uneventful and he is well with no signs of recurrence 6 years and 10 months after the first operation and 19 months after the second sleeve lobectomy     

One hundred and eleven liver resections for hilar bile duct cancer

A positive correlation between absence of residual tumor at resection margins and long-term survival in the treatment of hilar bile duct carcinoma has encouraged some surgeons to use a more radical approach, including liver/portal vein resection and combined pancreatoduodenectomy. However, if liver resection is associated with significant morbidity and mortality, it may not produce any overall benefit. This review was undertaken in an attempt to determine whether liver resection is a safe procedure and whether if has any beneficial effect over that of local bile duct excision alone, in terms of achieving curative resection and long-term survival. The records of 151 patients with hilar bile duct carcinoma surgically treated between June 1989 and December 1997 at the Asan Medical Center, Seoul, were retrospectively analyzed. Surgical resection was possible in 128 patients. The remaining 23 patients had surgical palliative drainage. Local bile duct excision alone was performed in 17 patients. Liver resection for tumor extending to secondary bile ducts or hepatic parenchyma was performed in 111 patients; portal vein resection was necessary in 29 of these 111 patients (26.1%) and pancreatoduodenectomy was combined in 18 patients (16.2%). Seven patients died during hospitalization after liver resection, an operative mortality of 6.3%. Margins of bile duct resection were free of tumor on histologic examination in 4 of the 17 local bile duct excisions, but in 86 of the 111 liver resections. The cumulative survival rate after local bile duct excision was 85.7% at 1 year, 42.9% at 2 years, 21.4% at 3 years, and 0% at 4 years. However, the survival rate after liver resection (excluding operative mortality) was 97.1% at 1 year, 72.8% at 2 years, 55.3% at 3 years, and 24.0% at 5 years. Survival and the percentage of patients with tumor-free resection margins after liver resection were superior to those after local bile duct excision. Resection of hilar bile duct carcinoma offers long-term survival only when surgery is aggressive and includes liver resection. Received for publication on July 2, 1998; accepted on July 5, 1998     

Carinal resection and reconstruction for recurrent lung cancer

A patient with a recurrent tumor in the trachea adjacent to the right main bronchus was treated by surgical resection 19 months after undergoing surgery for the primary cancer. The patient had previously undergone right upper lobectomy for T1N0M0 stage I squamous cell carcinoma. A carinal resection was performed which included 4 rings of the trachea, 2 rings of the righ main bronchus, and 1 ring of the left main bronchus. Reconstruction consisted of an end-to-end anastomosis of the trachea and left main bronchus, and an end-to-side anastomosis of the right and left main bronchi. The postoperative course was uneventful, and at present the patient is healthy 12 months following reoperation.

Extended bronchoplasty and angioplasty with a right upper-middle bilobectomy and S6 segmentectomy for lung cancer: a novel technique for anastomosis

In the lung cancer case described here, we resected the right upper lobe, right middle lobe, and superior segment of the right lower lobe with concomitant resection of the pulmonary artery and bronchoplastic and pulmonary arterial reconstruction. The basal segmental bronchus was anastomosed to the right main stem bronchus using a novel, specific technique: The tumor was extirpated with division of the upper and middle lobe bronchus and the superior segmental bronchus. Parts of the middle bronchus and superior segmental bronchus on the distal side were used to expand their orifice. The cut end of the pulmonary artery was sutured, reversing the long and short axes, to shorten and adjust the pulmonary artery.     

Surgical outcomes of ipsilateral metachronous second primary lung cancer

 Open in a separate windowOBJECTIVESThe optimal surgical approach for metachronous second primary lung cancer (MSPLC), especially ipsilateral MSPLC, remains unclear. This study aimed to review postoperative complications and examine surgical outcomes based on the extent of resection after surgery for ipsilateral MSPLC.METHODSClinical data from 61 consecutive patients who underwent pulmonary resection for ipsilateral MSPLC according to the Martini–Melamed criteria between January 2005 and December 2017 in 3 institutes were retrospectively reviewed.RESULTSPostoperative complications were identified in 12 patients (19.7%). Regarding the combination of initial and second surgery, intraoperative bleeding was significantly greater in patients with anatomic–anatomic resection than in others (P < 0.001). Operation time was significantly longer in patients with anatomic–anatomic resection than in others (P < 0.001). However, postoperative complications showed no significant differences based on the combination of surgeries. Five-year overall survival rates in patients with anatomic resection and wedge resection after second surgery were 75.8% and 75.8%, respectively (P = 0.738), and 5-year recurrence-free survival rates were 54.2% and 67.6%, respectively (P = 0.368). Cox multivariate analysis identified ever-smoker status (P = 0.029), poor performance status (P = 0.011) and tumour size >20 mm (P = 0.001) as independent predictors of poor overall survival, while ever-smoker status (P = 0.040) and tumour size >20 mm (P = 0.007) were considered independent predictors of poor recurrence-free survival.CONCLUSIONSRegarding postoperative and long-term outcomes for patients with ipsilateral MSPLC, surgical intervention is safe and offers good long-term survival. Wedge resection is an acceptable provided tumours ≤2 cm and ground-glass opacity-predominant as a second surgery for early-stage ipsilateral MSPLC.     

Endobronchial leiomyoma: Report of a case treated by bronchoplasty and a review of the literature

Endobronchial leiomyoma is exteemely rare. Most endobronchial leiomyomas reported in the literature have been resected by either lobectomy or pneumonectomy. We herein report a case treated by sleeve bronchoplasty without pulmonary resection. A 42-year-old woman was admitted to our hospital complaining of hemoptysis. Bronchoscopy revealed a lobulated tumor arising from the medial wall of the right main stem bronchus. A sleeve resection of the right main bronchus including the tumor and end-to-end anastomosis was performed. The histological diagnosis of the resected specimen was leiomyoma with no evidence of malignancy. The importance of early diagnosis and appropriate surgical treatment to preserve pulmonary function are emphasized. Similar cases of an endobronchial type of pulmonary leiomyoma reported in the literature are also reviewed.     

Extended resection for unexpected invasion of the left sided lung cancer into the liver: combined lung,diaphragm, and liver resection

Complete anatomic lung resection remains the best curative option in patients with early-stage lung cancer. In some cases, extended lung resections are required to achieve R0 resection. Although diaphragmatic invasion and resection is a well-known condition in lung cancer, direct invasion of the diaphragm and liver in lung cancer is rare. We report a 66-year-old man with left-sided lung cancer. Preoperative evaluation revealed the risk of diaphragm invasion, but the liver invasion was detected intraoperatively. In addition to left pneumonectomy, left-sided partial liver and diaphragm resection was performed. At 24 months from the operation, the patient is alive without any disease progression. We believe that combined resection including lung, diaphragm, and liver may have survival benefits in selected cases.     

Carinal resection after induction bronchial arterial infusion for locally advanced non-small cell lung cancer

We herein describe 3 cases of a carinal resection after induction bronchial arterial infusion (BAI) for locally advanced non-small cell lung cancer (NSCLC). Case 1 was a 44-year-old man with T1N2M0 adenocarcinoma. After undergoing Nd-YAG laser treatment (5079 J) and BAI [cis -diamminedichloro platinum (CDDP) 100 mg/body], a right sleeve upper lobectomy with a carinal resection and reconstruction (Montage type) was performed. Case 2 was a 67-year-old man with T4N1M0 squamous cell carcinoma. After BAI (CDDP 120 mg/body), an operation (same as case 1) was performed. Case 3 was a 72-year-old man with T4N2M0 squamous cell carcinoma. After BAI (CDDP 120 mg/body), a right sleeve peumonectomy was performed. There was neither BAI-related intraoperative nor postoperative complications. BAI with CDDP was thus found to be a useful and effective therapeutic modality for locally advanced NSCLC invading the carina.     

Pneumothorax manifesting primary lung cancer

Pneumothorax is a rare lung cancer manifestation. We report 2 patients in which pneumothorax occurred as a first manifestation of lung cancer. Postoperative lung tissue examination after pneumothorax showed lung cancer by chance. One patient had dissemination suspected due to ruptured bulla with adenocarcinoma. Both immediately underwent additional lobectomy with mediastinal lymphadenectomy after lung cancer was diagnosed, but we detected lung cancer recurrence in the bottom of the pleural cavity on the same side some 11 months after radical surgery in the patient suspected of dissemination. We could resect it completely, followed by adjuvant radiotherapy. The possibility of lung cancer should thus be considered in pneumothorax patients, even if middle-aged.     

Evaluation of limited resection of the lung for treatment of lung cancer

The validity and indications of limited resection for lung cancer were studied based on the results of 34 patients with lung cancer who underwent surgery. This method appeared to be an effective technique for the preservation of the cardiopulmonary function after surgery, particularly in elderly patients. The prognosis of those who underwent limited resection for selected cases was not significantly different from that of those treated by lobectomy. Recurrences were seen exclusively in Stage II patients, most of whom had a poorly differentiated type of cell pathology and developed blood vessel involvement. It was concluded from this study that this technique can be feasibly applied to patients with a tumor of less than 3 cm located at the periphery of the lung and with the histologic picture of highly differentiated type.     

Easier node dissection after chemoradiotherapy for lung cancer with collagen insertion at mediastinoscopy

Objective: Induction chemoradiotherapy followed by anatomical resection is a current therapeutic strategy for non-small-cell lung cancer with mediastinal node involvement. Dense peritracheal fibrosis and sclerosis after chemoradiotherapy cause difficult mediastinal node dissection. We evaluated a novel technique to make the mediastinal node dissection easier after induction therapy. Methods: At the end of mediastinoscopic node biopsy for staging of lung cancer, cotton-type collagen was inserted anterior and lateral to the trachea in patients with pathologically confirmed mediastinal node involve-ment (n=45). The induction therapy consisted of concurrent use of platinum-based chemotherapy and hyperfractionated radiotherapy. After the chemoradiotherapy all patients underwent a pulmonary resection with complete mediastinal node dissection 7–12 weeks after the collagen insertion. Surgical findings of the mediastinum and the time for node dissection were compared with those without collagen insertion at mediastinoscopy after chemoradiotherapy (n=5). Results: All five patients without collagen insertion showed sclerotic and fibrotic change of mediastinal nodes with severe adhesion to the trachea. In 42 of 45 patients with collagen insertion (93.3%) the collagen remained unabsorbed and separated the mediastinal nodes from the trachea. Mediastinal node dissection was easily accomplished by removing mediastinal tissues lateral and anterior to the collagen. The rate of mediastinal node separation was significantly higher with collagen insertion than without (p< 0.0001). The times for node dissection in patients with and without collagen insertion showed no significant difference. Conclusion: Cotton-type collagen insertion at staging mediastinoscopy for lung cancer separates the mediastinal nodes from the trachea and makes the node dissection easier after induction chemoradiotherapy.     

Metastasis of thyroid cancer to primary lung cancer

We present a case of a 65-year-old woman whose thyroid cancer metastasized to the lesion of primary lung cancer. Ten years after total thyroidectomy for thyroid cancer, chest radiograph by medical checkup demonstrated three nodular lesions in the bilateral lung fields. Segmental resection of the left S6, partial resection of right S4 and left S10 were performed to remove those lesions. Histologically, small nodules in the right S4 and S10 were diagnosed as a metastatic tumor of thyroid and well differentiated adenocarcinoma, respectively. Left S6 lesion 1.5 cm in diameter was also diagnosed as well-differentiated adenocarcinoma (Noguchi type C), however, small metastatic foci of papillary adenocarcinoma was identified within the lesion which revealed to be “cancer in cancer metastasis”. Metastasis of cancer to another primary cancer is a rare event. We discuss interesting phenomenon of cancer in cancer metastasis with a review of the literature.     

Clinical analysis of tracheoplasty and bronchoplasty in primary lung cancer

In our department, there were 482 thoracic surgeries for primary lung cancer between 1994 and 2007. We clinically reviewed cases that underwent tracheoplasty or bronchoplasty (n = 22, 4.6%). The patients consisted of 21 males and 1 female (66.5 +/- 12.0 years-old). All patients were smokers. The tissue forms were 19 squamous cell carcinomas, 2 adenocarcinomas, 1 large cell carcinoma, 1 adenoid cystic carcinoma and 1 carcinoid, including 2 multiple carcinomas. Sleeve resections involved the trachea in 1, upper lobes in 13, lower lobes in 3, upper-middle lobes in 2 and intermediate bronchus in 1. Wedge resections were performed in the upper lobes in 2. Fourteen reconstructions were performed. We ordinarily sutured the trachea and bronchus in any case, using a single outside knot. There was no leakage at the anastomosis. There were 2 hospital deaths. There were 4 cancer deaths, including 2 local recurrences. There were 4 patients demonstrating stenosis post operatively. There were 3 stenoses among 4 preoperative radiation therapies. We considered that radiation therapy disturbed the repair of the anastomosis. There were 8 pneumonia patients who developed post operatively. There were 2 operative hospital deaths among 3 angio-bronchoplasties without coverage. Recently, we have routinely covered the anastomosis at the reconstruction site and have not experienced any major complications.     

Robot-assisted thoracoscopic lung resection aimed at solo surgery for primary lung cancer

The surgical robotic system has been advanced as a tool that enables surgeons to perform precision operations of high quality. Many reports have been presented in cardiovascular surgery using the robotic system, but its use is uncommon in general thoracic surgery. We describe our two experiences with single-surgeon video-assisted thoracoscopic surgery lobectomy for primary lung cancer using a remote-controlled robot, named Naviot, to manipulate an endoscope. We believe that Naviot might be one of the robotic devices whose use could lead to solo surgery, even for complicated thoracoscopic procedures such as anatomical pulmonary resections with lymph node dissection.
