ObjectiveTo explore the safety and feasibility of uni-portal video-assisted thoracic surgery (VATS) for the treatment of bronchopulmonary sequestration (BPS). MethodsThe clinical data of BPS patients with surgical resection in Shanghai Pulmonary Hospital from February 2010 to June 2021 were reviewed. The patients were divided into a VATS group and a thoracotomy group according to the operation method. The operation time, intraoperative blood loss, hospital stay and postoperative complication rate were compared between the two groups. The VATS group was subdivided into a uni-portal VATS group and a multi-portal VATS group for subgroup analysis. ResultsFinally 131 patients were enrolled, including 62 males and 69 females with an average age of 39.3±13.2 years. There were 103 patients in the VATS group and 28 patients in the thoracotomy group. A total of 104 patients were diagnosed with left lower BPS, 26 with right lower BPS and 1 with bilateral lower BPS. The main symptom was cough (88 patients, 67.2%). There were 119 patients diagnosed by thoracic enhanced CT before operation. Compared with the thoracotomy group, the operation time was not statistically different (P=0.717), but the blood loss was less, the rate of postoperative complication was lower and hospital stay was shorter in the VATS group (P＜0.05). The rate of conversion to open surgery in the uni-portal VATS group and multi-portal VATS group was 11.8% and 13.5%, respectively. Meanwhile, patients in the uni-portal VATS group had shorter operation time and postoperative hospital stay, less blood loss and lower postoperative complication rate than those in the multi-portal VATS group (P＜0.05). Conclusion In order to improve the rate of diagnosis, the lung enhanced CT scan should be selected as an optimal noninvasive method in adult suspected patients (especially those with solid cystic and solid lesions in the lower lobe). Uni-portal VATS is a safe and feasible method for BPS which can be widely promoted.
目的 总结肺隔离症的临床特点、诊断方法及治疗的经验，降低误诊率，提高治疗水平。 方法 回顾性分析福州总医院2002年7月－2012年6月收治的27例肺隔离症患者的临床诊治手段。 结果 27例肺隔离症患者中，术前确诊仅有18例，误诊为肺部良性肿瘤3例，肺脓肿3例，支气管扩张2例，纵隔肿瘤1例。行外科切除的患者有19例，其中13例经胸腔镜手术，6例开胸手术，均无复发；行支气管动脉数字减影血管造影栓塞术8例，其中再发咯血1例来院行手术治疗。 结论 外科治疗是目前肺隔离症治疗的主要方法。围手术期积极控制感染对治疗的成功有显著意义。
ObjectiveTo explore the status,reasons and precautions of misdiagnosis of pulmonary sequestration. MethodsSeventy-seven articles about pulmonary sequestration published in Wanfang and CNKI databases between January 2005 and December 2013 were retrospectively analyzed,of which 41 articles referring to misdiagnosis rate.The misdiagnosis rate,time,status,consequence,reason and main means of definite diagnosis were analyzed. ResultsThe total number of cases of pulmonary sequestration in the 41 articles was 689,in whom 399 cases were misdiagnosed.Misdiagnosis rate was 57.91%.The minimum misdiagnosis time was 14 days and the maximum was 40 years.Pulmonary sequestration was most often misdiagnosed as pulmonary cyst(23.16%),bronchiectasis(22.73%),lung cancer(20.08%),lung abscess(6.93%)and pneumonia(6.28%).Most misdiagnosed patients did not suffer adverse consequences,except 4 patients were dead and 1 patient undertook unnecessary extended operation.Lack of specificity in clinical manifestations,lack of awareness of the disease,diversity of imaging performance and complications covering the original disease were the most common reasons of misdiagnosis.Postoperative pathological examination(83.77%),intraoperative findings(13.42%)and computed tomography angiography(2.16%)were the main means of definite diagnosis in misdiagnosed cases. ConclusionPulmonary sequestration is lack of specificity in clinical manifestations and easy to be misdiagnosed.Imaging showing the abnormal blood supply vessels is the key to the diagnosis.Improving the awareness of it can reduce misdiagnosis and incorrect treatment.
ObjectiveTo compare the clinical efficacy between right visual double lumen tube (VDLT) intubation and right common double lumen tube (DLT) intubation in lung isolation technique. MethodsA total of 57 patients undergoing thoracoscopic surgery with right DLT lung isolation technique in the First People's Hospital of Chenzhou City and West China Hospital from June 2020 to June 2021 were randomly divided into two groups: a DLT group (n=29, 16 males and 13 females, with a mean age of 54.3±13.2 years) and a VDLT group (n=28, 18 males and 10 females, with a mean age of 55.1±13.7 years) at 1 : 1 with random number table generated by the computer. The clinical data of the two groups were compared. ResultsCompared with the DLT group, the catheter positioning time in the VDLT group was statistically shorter (74.9±47.5 s vs. 151.6±88.9 s, P<0.001), the right upper lung occlusion rate (21.4% vs. 51.7%) and the intraoperative re-adjustment catheterization rate (14.3% vs. 48.3%) were lower (P<0.05). The quality of lung collapses immediately after thoracotomy (67.9% vs. 24.1%) and 20 minutes after thoracotomy (100.0% vs. 75.9%) were improved (P<0.05). There was no significant difference in the rate of fiberoptic bronchoscope assistance for positioning, or the incidence of pharynx pain and hoarseness between the two groups (P>0.05). ConclusionCompared with common DLT, VDLT is more efficient, accurate and intuitive in the location of right bronchial intubation.
