Argon plasma coagulation in bronchology: a new method--alternative or complementary?

Argon plasma coagulation (APC) is a thermal coagulation technique that uses ionized argon to transmit high-frequency electrical current, contact free, to tissue. APC has been used in surgery for more than 20 years, particularly for the hemostasis of superficial bleeding. Although APC has become well established in gastrointestinal endoscopy since its introduction in 1991, very few reports of its use in bronchoscopy exist to date. From June 1994 to June 1998, 364 patients (80 women, 284 men), 88% with a confirmed malignant tumor, were treated prospectively in a total of 482 sessions. The single most common indication was recanalization of malignant airway stenoses (186 patients). The defined therapy objective was achieved with good results in 67% of patients. More than 90% of interventions were performed with rigid bronchoscopy. Despite less penetration compared with Nd:YAG laser, extensive bronchial tumors were treatable, in which coagulated tumor fractions were removed either with forceps or bronchoscope tip. The second indication was bleeding in the central airways (119 patients). Acute hemostasis was achieved in 118 patients, 20% in whom the flexible technique under local anesthesia was used. In 34 patients, APC was successfully used to recanalize occluded stents. Rare indications included benign endobronchial tumor, fistula conditioning before fibrin adhesion, and the treatment of scar tissue stenosis. Summarizing all complications, a rate of 3.7% "per treatment" was recorded. Two patients died within 24 hours; their deaths were not directly related to APC. APC is an effective and safe technique for the treatment of bronchologic tumor ablation and hemostasis and can be used with local anaesthetic with flexible bronchoscopy or rigid bronchoscopy with general anesthesia. Compared with Nd:YAG laser, APC is an economic alternative technique offering more effective hemostasis. Furthermore, APC is of particular value as a compliment to well-known techniques, increasing the options in interventional bronchoscopy.     

经支气管镜治疗良性瘢痕增生性气道狭窄方法的比较

目的 通过临床病例资料的分析,对厅前常用的治疗良性瘢痕性气道狭窄的介入技术进行评价,并对影响疗效的相关因素进行讨论.以期寻找最佳的治疗方法.方法 研究选择2004年12月至2009年12月收入北京天坛医院呼吸科的良性瘢痕增生性气道狭窄患者36例,其中男15例、女21例,年龄13～82岁,平均(40±21)岁.根据采用的介入治疗方法不同将患者分为3组,A组使用电凝治疗;B组经电凝治疗后改为针形电刀、球囊扩张和(或冷冻治疗);C组不使用电凝治疗,采用球囊扩张、冷冻和(或)针形电刀治疗.评价不同介入处理方法的疗效及并发症情况,各组间病例资料的比较采用四格表卡方检验.结果 36例患者中治愈9例,治愈率为25%(9/36),有效10例,总体有效率为53%(19/36);无效12例,失败5例,总体无效率47%(17/36).其中电凝治疗有效者1例(1/12,8%),治疗后狭窄段延长8例(8/12,67%);球囊扩张及冷冻和(或)针形电刀治疗有效者14例(14/17,82%),治疗后狭窄段延长2例(2/17,12%).与电凝治疗相比,球囊扩张及冷冻和(或)针形电刀治疗的有效率明显提高,再狭窄率明显减少.结论 急性期气道复张治疗中,目前常用的电凝方法可加重气道再狭窄并最终导致治疗失败,而急性期应用球囊扩张联合针形电刀及冷冻是较为合理且有效的气道复张治疗方法.

Abstract：

Objective To evaluate the efficacy of different interventional bronchoscopic techniques for the management of benign cicatricial hyperplasia airway stenosis,and to study the factors associated with the treatment effects.Methotis From December 2004 to December 2009,36 patients with cicatricial airway stenosis were admitted to our department.An investigation was made to analyze the effects by different interventional bronchoscopie treatments.The most suitable treatment modality for cicatricial airway stenosis was explored and described.Results For the 36 patients,the disease was cured in 9,improved in 10,not improved in 12,and failure in 5.The care rate,effective rate and ineffective rate were 25%,53%and 47%,respectively.Further analysis showed that the effective rate was 8%and 82%respectively for the electrical coagulation therapy and the balloon dilation eombined with needle electrical knife and/or cryotherapy.Restenosis extension after operation occurred in 67%of the cases by electrical coagulation therapy,but only 12% of casesby the balloon dilation combined with needle electrical knife and/or cryotherapy.Conclusions Our experience demonstrated that for the treatment of airway cicatricial stenosis,electrical coagulation might induce and worsen serious airway restenosis resulting in failure of treatment.On the other hand,balloon dilation combined with needle dectrical knife and/or cryotherapy might be a relative safe and effective therapy for airway cicatricial stenosis.     

Interventional bronchoscopy in the management of airway stenosis due to tracheobronchial tuberculosis

STUDY OBJECTIVES: To assess the efficacy and complications of interventional bronchoscopic techniques in treating airway stenosis due to tracheobronchial tuberculosis. DESIGN: Case series. SETTING: Respiratory care centers at two tertiary care referral teaching hospitals in Japan, Hiroshima City Hospital and Okayama Red Cross Hospital. PATIENTS AND INTERVENTIONS: A total of 30 patients were admitted to the hospital with a diagnosis of tracheobronchial tuberculosis between January 1991 and January 2002. Of those 11 patients received interventional bronchoscopy, including stent placement, laser photoresection, argon plasma coagulation (APC), balloon dilatation, cryotherapy, and endobronchial ultrasonography (EBUS). One patient with complete bronchial obstruction underwent a left pneumonectomy. RESULTS: Six patients underwent stent placement after balloon dilatation, while the remaining five patients underwent only balloon dilatation. In six patients, Dumon stents were successfully placed to reestablish the patency of the central airways. Two patients first had Ultraflex stents implanted but had problems with granulation tissue formation and stent deterioration caused by metal fatigue due to chronic coughing. Dumon stents then were placed within the Ultraflex stents after the patient had received treatment with APC and mechanical reaming using the bevel of a rigid bronchoscope. In four patients, EBUS images demonstrated the destruction of bronchial cartilage or the thickening of the bronchial wall. The main complications of Dumon stents are migration and granulation tissue formation, necessitating stent removal, or replacement, and the application of cryotherapy to the granuloma at the edge of the stent. CONCLUSION: Interventional bronchoscopy should be considered feasible for management of tuberculous tracheobronchial stenosis. Dumon stents seem to be appropriate, since removal or replacement is always possible. Ultraflex stents should not be used in these circumstances because removal is difficult and their long-term safety is uncertain. EBUS could provide useful information in evaluating the condition of the airway wall in cases of tracheobronchial tuberculosis with potential for bronchoscopic intervention.

Abstract：

Objective To explore the etiology, clinical features, diagnosis and treatment of central airway obstruction (CAO), and therefore to raise awareness of this disease.Methods Forty patients with central airway obstruction were analyzed retrospectively and their clinical characteristics were described.Results Among these 40 cases of CAO, the diagnoses included squamous cell carcinoma (n = 13 ),adenoid cysts ( n = 5 ) , esophageal squamous cell carcinoma ( n = 4 ) , and benign tumor ( n = 6 ).The presenting symptoms included cough(n = 36), shortness of breath or difficulty breathing(n = 21 ), and bemoptysis or bloody sputum which was more common in cases with airway squamous cell carcinoma ( n =11 ).All the patients underwent chest CT examination, and the lesions were evident in all the cases.Twenty-one cases underwent three-dimensional reconstruction of the airway.Six patients underwent pulmonary function test, and ventilatory abnormalities were revealed, and showed the characteristic blunting of the flow-volume loop.Thirty-nine cases underwent bronchoscopy and correct clinical diagnosis was made.Eleven patients received interventional therapy with argon plasma coagulation ( APC ), and their symptoms were all relieved within 2 days.Conclusions CAO may be caused by variety of diseases, but the most common cause is malignancy.The common symptoms of CAO are cough and dyspnea.Chest CT with airway reconstruction, bronchoscopy and pathological examination can provide accurate information for diagnosis.The choice of treatment modalities depends on the size, location and the pathology of the lesions.APC is a safe and effective therapy for short-term management of malignant lesions.
