A VATS lobectomy for lung cancer in a patient with an anomalous pulmonary vein: Report of a case

A video-assisted right upper lobectomy was successfully performed on a 58-year-old man with an anomalnous segmental pulmonary vein. The tumor was a peripherally located adenocarcinoma. The anomalous vein behind the right main bronchus was identified and safely divided. This case emphasized that to perform this procedure successfully, (1) a careful preoperative evaluation of the anatomy, including the presence of any possible vascular and/or bronchial anomalies, is necessary, and (2) if any anatomical structures cannot be determined intraoperatively, a conversion into an open procedure must immediately be undertaken.     

A cost-effective thoracoscopic treatment strategy for pediatric spontaneous pneumothorax

Background: Recent data suggest that children have a higher incidence of recurrence than adults after nonoperative treatment of primary spontaneous pneumothorax (PSP). Video-assisted thoracoscopic surgery (VATS) allows efficacious therapy with significantly less morbidity. We attempt to define the most cost-effective clinically efficacious strategy using VATS to manage pediatric PSP. Methods: We retrospectively reviewed all admissions to a tertiary care children's hospital for PSP between January 1, 1991 and June 30, 1996. Results: Fifteen children had 29 primary or recurrent PSPs. Mean patient age was 14.8 ± 1.1 years, boy–girl ratio 4:1, median body mass index 18 (normal, 20–25), and 67% of pneumothoraces left sided. All patients were managed initially nonoperatively: 14 with tube thoracostomy drainage and 1 with oxygen alone. Of the children initially managed nonoperatively, 57% had a recurrent pneumothorax, and 50% of these patients eventually developed contralateral pneumothoraces. Nonoperative treatment for recurrence resulted in a 75% second recurrence rate. In contrast, eight children who underwent operative management had a 9% incidence of recurrence. The total for charges accrued in treating 29 pneumothoraces in these 15 patients was approximately $315,000. In the same population, the estimated charges for initial nonoperative therapy followed by bilateral thoracoscopy after a single recurrence would be $230,000. Conclusions: A cost-effective treatment strategy for pediatric primary spontaneous pneumothorax is tube thoracostomy at first presentation, followed by VATS with thoracoscopic bleb resection and pleurodesis for patients who experience recurrent pneumothorax.

胸腔镜治疗食管癌术后乳糜胸

目的：探讨胸腔镜手术在食管癌手术后乳糜胸治疗中的作用。方法2012年1月至2013年12月,应用胸腔镜经右胸入路行胸导管结扎治疗食管癌术后并发乳糜胸16例。结果16例患者均在胸腔镜下完成手术。手术时间40～90 min,平均65 min。术后引流时间4～9天,平均引流时间5．5天。术后无严重并发症,随访6个月无复发。结论胸腔镜治疗食管癌术后乳糜胸是一种安全、有效的治疗方法。手术后并发乳糜胸应尽早行胸腔镜手术干预,有助于患者的早日康复,减少住院时间。     

I期肺腺癌VATS肺叶切除与亚肺叶切除预后比较

背景与目的美国国立综合癌症网络（National Comprehensive Cancer Network, NCCN）指南推荐,大部分可手术切除的肺癌首选电视辅助胸腔镜手术（video-assisted thoracoscopic surgery, VATS）解剖性肺叶切除。而研究证实肺段切除I期肺癌对肺功能的保护优于肺叶切除。目前,临床上对I期肺腺癌VATS亚肺叶切除能否获得与肺叶切除同等疗效仍未确定,现分析两种手术方式治疗I期肺腺癌预后的比较。方法回顾性研究2009年1月-2011年12月广州医科大学附属第一医院收治的I期肺腺癌患者,其中VATS肺叶切除222例,亚肺叶切除36例;对两组患者使用倾向评分匹配（propensity score matching, PSM）,比较两组患者的临床病理特征及生存预后。结果两组匹配患者35例,匹配后VATS肺叶切除组与亚肺叶切除组的术后无病生存期（disease free survival, DFS）分别为49.3个月、42.7个月,差异无统计学意义（P=0.137）;两组术后总生存期（overall survival, OS）分别为50.3个月、49.0个月,差异无统计学意义（P=0.122）。分期分层结果示,Ia期肺叶切除和亚肺叶切除两组术后DFS差异无统计学意义;而Ib期肺叶切除和亚肺叶切除两组术后DFS差异有统计学意义。结论 Ia期肺腺癌VATS亚肺叶切除的生存预后不亚于肺叶切除,Ib期肺腺癌建议选择VATS肺叶切除治疗。

A pilot study of intraoperative localization of peripheral small pulmonary tumors by cone-beam computed tomography: sandwich marking technique

BackgroundIntraoperative identification of small pulmonary nodules has been an important technical issue. We aimed to develop a new localization method which is much safer and simple procedure compared with conventional methods.MethodsThis was a retrospective study including patients with resected peripheral pulmonary nodules between November 2017 and April 2021 at Teikyo University School of Medicine, and Saitama Cardiovascular and Respiratory Center. All surgical procedure was wedge resection, and the tumor size was equal to or less than 20 mm which were detected by cone-beam computed tomography (CBCT; Philips Allura Xper FD 20, Philips). Some metal clips were put on several places of visceral pleura, where the target lesion was sandwiched by marking clips (sandwich marking technique). CBCT detected both the target lesion and metal clips, and video-assisted thoracoscopic surgery (VATS) was performed. Radiological and pathological findings were analyzed, and the correlation coefficient of tumor size was examined among pre-, intra-, and post-operative tumor sizes.ResultsThe average age of 90 patients was 65.2 years, and 47 were male (52.2%). All procedure was wedge resection including twelve bi-wedge resections, and one hundred nine peripheral pulmonary lesions were obtained by sandwich marking technique. The detection rate was 100%, and there was no marking-related complication.ConclusionsAll small peripheral pulmonary lesions were successfully detected and resected by using CBCT with no marking-related complication. Sandwich marking technique was demonstrated to provide safe, reliable, and simple localization procedure for small peripheral pulmonary lesions.     

Preoperative localization of lung nodules: a comparative analysis of hookwire and radio-guided procedures

BackgroundHistological diagnosis of pulmonary nodules requires surgical resection on many occasions. There are multiple localization strategies each with their own benefits and complications. The objective of this study is to compare preoperative lung nodule localization with hookwire and radiotracer injection (radioguided occult lesion localization, ROLL). To compare results, complications, and volume of the sample resected with both techniques.MethodsPatients undergoing resection of pulmonary nodules with video-assisted thoracoscopy and pre-surgical localization with hookwire or ROLL were studied. Eighty-eight pulmonary nodules were resected in 76 patients: 52 with a hook wire and 36 with a radiotracer. The localization rate, the shortest distance between the nodule and the pleura, the intrapulmonary distance of the locator, the complications, the volume of the resection piece, and the histological result were all assessed. In addition, the factors that influence the volume of the surgical piece were analyzed.ResultsAll the nodules were resected with both techniques. The intrapulmonary path of the locator is longer for the ROLL group (23.91 vs. 16.28 mm; P=0.04), with no differences in the distance from the nodule to the pleura. The rate of pneumothorax was significantly higher after the placement of a hook wire (69.2% vs. 24.2%; P<0.0001), while there were no differences in the presence of hemorrhage. The volume of the pieces resected using ROLL was more minor than with hookwire, although not statistically significant (20.19 vs. 34.26 cc; P=0.07).ConclusionsPreoperative localization with the ROLL technique is safer than the placement of hookwire. In addition, the ROLL technique shows a tendency to obtain a smaller volume of resected tissue since the marking is not affected by the intrapulmonary route used during marker placement. ROLL technique allows to locate lung nodules with fewer complications than hookwire and probably gets smaller resection samples.
