연구배경 : 최근의 비디오 영상기술, 내시경 수술기구 및 내시경 수술기법의 눈부신 발달에 힘입어 흉강경의 영역이 단순한 늑막질환 진단에서 여러가지 흉부질환의 치료 방법으로 넓어졌다. 비디오 흉강경 수술(VATS) 방법은 3년전에 개발된 새롭고 가히 매력적이라 할 만한 흉부질환 수술방법으로 서울대학교병원에서도 1992년 7월에 도입하여서 비록 짧은 기간이지만 여러가지 임상경험을 하였기에 그 결과를 분석한다. 방법 : 1992년 7월부터 1993년 4월까지 10개월간 30명 환자에게 31예의 비디오 흉강경 수술을 시행하였다. 폐기포 절제술이 18명(19예), 종격동 종양 절제술이 4예, 폐실질 폐조직 생검 3예, 늑막생검 3예, 늑막종괴제거술 1예 그리고 늑막심낭창형성술 1예였다. 결과 : 사망예는 없으며 8예의 합병증이 발생하였다. 장기간공기누출이 3예, 장기간 늑막액 유출이 2예, 기흉재발 1예, 호너씨 증후군 1예, 애성 1예였다. 31예 모두 비디오흉강경 자체로 수술을 완료하였다. 합병증이 없었던 자연기흉 환자들의 술후 입원기간은 5일정도로 평상적인 개흉술로 수술받은 환자보다 입원기간이 약간 짧았다. 결론 : 비록 비디오 흉강경 수술은 초기단계라서 비교적 술후 합병증 빈도가 높았지만 이러한 술식이 통증감소, 입원기간단축, 빠른 회복, 미용적으로 우수한 작은 수술 상처 등의 여러가지 장점을 갖고 있어 환자들에게 매우 유익하다고 확신한다. 비디오 흉강경수술의 영역은 앞으로 흉곽내 여러가지 질환의 진단과 치료에 사용되고 심지어 심장병질환에도 응용될 것이라 생각된다.

Background: We report our surgical technique for nonintubated uniportal video-assisted thoracoscopic surgery (VATS) pulmonary resection and early postoperative outcomes at a single center. Methods: Between January and July 2017, 40 consecutive patients underwent nonintubated uniportal VATS pulmonary resection. Multilevel intercostal nerve block was performed using local anesthesia in all patients, and an intrathoracic vagal blockade was performed in 35 patients (87.5%). Results: Twenty-nine procedures (72.5%) were performed in patients with lung cancer (21 lobectomies, 6 segmentectomies, and 2 wedge resections), and 11 (27.5%) in patients with pulmonary metastases, benign lung disease, or pleural disease. The mean anesthesia time was 166.8 minutes, and the mean operative duration was 125.9 minutes. The mean postoperative chest tube duration was 3.2 days, and the mean hospital stay was 5.8 days. There were 3 conversions (7.5%) to intubation due to intraoperative hypoxemia and 1 conversion (2.5%) to multiportal VATS due to injury of the segmental artery. There were 7 complications (17.5%), including 3 cases of prolonged air leak, 2 cases of chylothorax, 1 case of pleural effusion, and 1 case of pneumonia. There was no in-hospital mortality. Conclusion: Nonintubated uniportal VATS appears to be a feasible and valid surgical option, depending on the surgeon's experience, for appropriately selected patients.

Background: Uniportal video-assisted thoracoscopic surgery (VATS) has proven safe and effective for pulmonary wedge resection and lobectomy. The objective of this study was to evaluate the safety and feasibility of uniportal VATS segmentectomy by comparing its outcomes with those of the multiportal approach at a single center. Methods: The records of 84 patients who underwent VATS segmentectomy from August 2010 to August 2018, including 33 in the uniportal group and 51 in the multiportal group, were retrospectively reviewed and analyzed. Results: Anesthesia and operative times were similar in the uniportal and multiportal groups (215 minutes vs. 220 minutes, respectively; p=0.276 and 180 minutes vs. 198 minutes, respectively; p=0.396). Blood loss was significantly lower in the uniportal group (50 mL vs. 100 mL, p=0.013) and chest tube duration and hospital stay were significantly shorter in the uniportal group (2 days vs. 3 days, p=0.003 and 4 days [range, 1-14 days] vs. 4 days [range, 1-62 days], p=0.011). The number of dissected lymph nodes tended to be lower in the uniportal group (5 vs. 8, p=0.056). Conclusion: Our preliminary experience indicates that uniportal VATS segmentectomy is safe and feasible in well-selected patients. A randomized, prospective study with a large group of patients and long-term follow-up is necessary to confirm these results.

Background: Major intraoperative hemorrhage reportedly predicts unfavorable survival outcomes following surgical resection for esophageal carcinoma (EC). However, the factors predicting the amount of blood lost during thoracoscopic esophagectomy have yet to be sufficiently studied. We sought to identify risk factors for excessive blood loss during video-assisted thoracoscopic surgery (VATS) for EC. Methods: Using simple and multiple linear regression models, we performed retrospective analyses of the associations between clinicopathological/surgical factors and estimated hemorrhagic volume in 168 consecutive patients who underwent VATS-type esophagectomy for EC. Results: The median blood loss amount was 225 mL (interquartile range, 126-380 mL). Abdominal laparotomy (p<0.001), thoracic duct resection (p=0.014), and division of the azygos arch (p<0.001) were significantly related to high volumes of blood loss. Body mass index and operative duration, as continuous variables, were also correlated positively with blood loss volume in simple linear regression. The multiple linear regression analysis identified prolonged operative duration (p<0.001), open laparotomy approach (p=0.003), azygos arch division (p=0.005), and high body mass index (p=0.014) as independent predictors of higher hemorrhage amounts during VATS esophagectomy. Conclusion: As well as body mass index, operation-related factors such as operative duration, open laparotomy, and division of the azygos arch were independently predictive of estimated blood loss during VATS esophagectomy for EC. Laparoscopic abdominal procedures and azygos arch preservation might be minimally invasive options that would potentially reduce intraoperative hemorrhage, although oncological radicality remains an important consideration.

Lobectomy with mediastinal node dissection has been standard treatment for non-small cell lung cancer (NSCLC). Nowadays, video-assisted thoracoscopic surgery (VATS) is gaining acceptance as an alternative treatment option, given the quality-of-life benefits that it confers. For the VATS procedure, most surgeons create two or three ports with a utility incision of 3 to 5 cm. However, with acquired skill and instrumentation advances, single-incision thoracoscopic surgery has emerged over time. Here, we report the case of an 86-year-old female with NSCLC treated by single-incision segmentectomy.

Video-assisted thoracic surgery [VATS is emerging as a viable alternatives to thoracotomy when surgical treatment of spontaneous pneumothorax is required.Apical blebs and bullaes of the lung can be resected,and pleural abrasion can be accomplished with minimal postoperative pain and a shorter postoperative stay in hospital. We compared our results with thoracoscopic management of spontaneous pneumothorax in 20 patients [group I with a group of 32 patients previously subjected to lateral limited thoracotomy [group II . Indications for operation, sex distribution, and average age [groupI, 24.7 years ; group II, 34.4 years were comparable. Operation time [112.42 54.7 min versus 124.8 35.3 min ; P 0.03 and chest tube duration [64.4 52.3 hours versus 97.7 45.4 hours ; P 0.01 were less in group I. Postoperative hospital stay was less in group I[3.84 0.99 days;P 0.01 , as was the use of parenteral narcotics after 48 hours. [5/20=25% versus25/32=78% . Pain was quantitated by verbal rating scale in postoperative 1 to 3 days. Patients undergoing VATS experienced significantly less postoperative pain. Postoperative complication was less in group I[1/20=5% versus 3/32=8.3% . In conclusion, Video-assisted thoracoscopic management of spontaneous pneumothrax allows performance of the standard surgical procedure while avoiding the thoracotomy incision.Video-assisted thoracic surgery [VATS is safe and offers the potential benefits of shorter postoperative hospital stays and less pain with cosmetic benefits.

Esophageal duplication cyst is very rare mediastinal tumor which is congenital lesion of the esophagus. Esophageal duplication cyst could be excised with video assisted thoracoscopic surgery(VATS) if it is relatively small, cystic lesion and not adhered severely to the surrounding tissues such as lung, trachea, bronchus, esophagus and pleura. We report a case of an esophageal duplication cyst which was located in the right thoracic cavity below carina and could be excised completely and repaired by interrupted suture with 3.0 black silk. The patient was discharged at 10 days after operation with good condition and has been in uneventful condition 2 months after operation.

Background: A recent increase in the incidental detection of ground glass nodules (GGNs) has created a need for improved diagnostic accuracy in screening for malignancies. However, surgical diagnosis remains challenging, especially via video-assisted thoracoscopic surgery (VATS). Herein, we present the efficacy of a novel electrical navigation system for perioperative percutaneous transthoracic nodule localization. Methods: Eighteen patients with GGNs who underwent electromagnetic navigated percutaneous transthoracic needle localization (ETTNL), followed by 1-stage diagnostic wedge resections via VATS between January and December 2020, were included in the analysis. Data on patient characteristics, nodules, procedures, and pathological diagnoses were collected and retrospectively reviewed. Results: Of the 18 nodules, 17 were successfully localized. Nine nodules were pure GGNs, and the remaining 9 were part-solid GGNs. The median nodule size was 9.0 mm (range, 4.0-20.0 mm); and the median depth from the visceral pleura was 5.2 mm (range, 0.0-14.4 mm). The median procedure time was 10 minutes (range, 7-20 minutes). The final pathologic results showed benign lesions in 3 cases and malignant lesions in 15 cases. Conclusion: Perioperative ETTNL appears to be an effective method for the localization of GGNs, providing guidance for a 1-stage VATS procedure.
