RESUMO
Background: Uniportal thoracoscopic surgery has become widely accepted for its favourable outcomes with regard to pain. However, post-operative pain is still a concern associated with thoracic surgery. The objective of this study was to evaluate the post-operative pain of patients undergoing uniportal video-assisted thoracoscopic surgery (VATS) lobectomies using an intra-operative intercostal nerve block. Methods: All consecutive patients undergoing uniportal VATS lobectomies between October 2018 and October 2019 were reviewed retrospectively. Twenty consecutive patients in Group A underwent uniportal VATS lobectomies without intra-operative intercostal nerve blocks. The other 20 consecutive patients in Group B underwent uniportal VATS lobectomies with intra-operative intercostal nerve blocks. Numeric Pain Rating Scale (NRS) scores were recorded at 1, 12 and 24 h postoperatively. The number of anti-inflammatory drugs (non-steroidal anti-inflammatory drug [NSAIDs]) consumed until the time of chest tube removal was also recorded. Results: There was no difference between the groups with regard to sex, age, chest tube duration, length of stay, operative time or laterality. There was a significant difference in post-operative NRS scores at 1 h (P < 0.001) and 12 h (P = 0.014) between the groups. The NSAID consumption was significantly lower in Group B than in Group A (P = 0.038). Conclusion: Intra-operative intercostal nerve blocks with bupivacaine provided immediate post-operative pain relief and reduced post-operative opioid consumption in patients who underwent uniportal VATS lobectomies.
RESUMO
BACKGROUND AND AIMS: Uniportal thoracoscopic surgery has been reported to result in alleviating the postoperative pain when compared with traditional video-assisted thoracoscopic surgery (VATS). However, postoperative pain is still the main concerns associated with thoracic surgeries. The objective of this study is to evaluate the postoperative pain of patients undergoing uniportal VATS, especially wedge resection, with the use of intraoperative intercostal nerve block. METHODS: All consecutive patients undergoing the uniportal VATS wedge resection between January 2019 and March 2020 were reviewed retrospectively. Twenty consecutive patients in Group A underwent the uniportal VATS wedge resection without intraoperative intercostal nerve block. The other 20 consecutive patients in Group B underwent the uniportal VATS wedge resection with intraoperative intercostal nerve block. The numeric pain rating scale (NRS) scores were recorded at 1, 12, and 24 h, postoperatively. The number of opioid consumption was also recorded until the time to chest tube removal. RESULTS: There was no difference between groups with regard to sex, age, chest tube duration, length of stay, operative time, laterality time, and diagnosis. There was a significant difference in postoperative NRS scores at 1 h (P = 0.001) and 12 h (P = 0.022) between the groups. The opioid consumption was significantly in Group B lower than those in Group A (P = 0.025). CONCLUSION: The intraoperative intercostal nerve block with bupivacaine provided immediate postoperative pain relief with reducing the postoperative opioid consumption compared in patients who underwent uniportal VATS, especially wedge resection of the lung.
RESUMO
BACKGROUND: An accurate diagnosis in patients with interstitial lung diseases (ILDs) by multidisciplinary discussion (MDD) based on histopathologic information is essential for optimal treatment. Transbronchial lung cryobiopsy (TBLC) has increasingly been used as a diagnostic alternative to surgical lung biopsy. This study aimed to evaluate the appropriate methods of TBLC in patients with ILD in Korea. METHODS: A total of 27 patients who underwent TBLC were included. TBLC procedure details and clinical MDD diagnosis using TBLC histopathologic information were retrospectively analyzed. RESULTS: All procedures were performed under general anesthesia with the fluoroscopic guidance in the operation room using flexible bronchoscopy and endobronchial balloon blocker. The median procedure duration was less than 30 minutes, and the median number of biopsies per participant was 2. Most of the bleeding after TBLC was not severe, and the rate of pneumothorax was 25.9%. The most common histopathologic pattern was alternative (48.2%), followed by indeterminate (33.3%) and usual interstitial pneumonia (UIP)/probable UIP (18.5%). In the MDD after TBLC, the most common diagnosis was idiopathic pulmonary fibrosis (33.3%), followed by smoking-related ILD (25.9%), nonspecific interstitial pneumonia (18.6%), unclassifiable-ILD (14.8%), and others (7.4%). CONCLUSION: This first single-center experience showed that TBLC using a flexible bronchoscopy and endobronchial balloon blocker with the fluoroscopic guidance under general anesthesia may be a safe and adequate diagnostic method for ILD patients in Korea. The diagnostic yield of MDD was 85.2%. Further studies are needed to evaluate the diagnostic yield and confidence of TBLC.
RESUMO
BACKGROUND: The subxiphoid single-port approach for thymectomy has advantages compared with conventional lateral transthoracic approaches. Most of centers use CO2 insufflation to secure an appropriate surgical field during subxiphoid thymectomy, which causes fighting between surgical instruments and restrictions on the types of surgical instruments. The objective of this study is to introduce an effective method to establish the subxiphoid approach without CO2 insufflation using a retractor and steel wire. METHODS: All consecutive 59 patients undergoing subxiphoid single-port thymectomy between August 2014 and August 2021 were reviewed retrospectively. RESULTS: We analyzed data of 59 patients (31 male and 28 female) with a median age of 59 years (range 50-68). Two (3.4%) patients presented postoperative complications. The conversion to a different approach was required in 4 (6.8%) cases. The median follow-up time was 23 months (range 10-41) and loco-regional recurrence was observed in one patient (1.7%). There were no intraoperative deaths and the postoperative mortality. No complications related to sternal wiring occurred. CONCLUSIONS: Subxiphoid single-port thymectomy without CO2 using a retractor and steel wire insufflation is a technically feasible method.

RESUMO
Backgrounds: The aim of our study is to describe the learning curve for uniportal video-assisted thoracoscopic surgery (VATS) lobectomy from our single center's experience for adopting it because uniportal VATS is generally considered a technically difficult procedure. Methods: A retrospective review of all 164 consecutive patients who underwent uniportal VATS lobectomy between June 2015 and February 2020 was done. A cumulative summation (CUSUM) method was applied to evaluate the learning curves of the operation time. Results: Among the 164 patients, the CUSUM value inflected at the 31st case. Ninety-five consecutive patients underwent uniportal VATS upper lobectomy. The other 69 consecutive patients underwent uniportal VATS lower lobectomy. The operation time CUSUM learning curve analysis revealed that the curves descended from the 21st case in upper lobectomy group and the 12th case in lower lobectomy group. Conclusion: Operators are required to experience at least 21 cases for upper lobectomy and 12 cases for lower lobectomy until the operation time is stabilized.

BACKGROUND: The subxiphoid single-port approach for thymectomy has several advantages compared with conventional lateral transthoracic approaches. However, perioperative outcomes of subxiphoid single-port thymectomy are still lacking. The objective of this study is to present our 6-year experience of subxiphoid single-port thymectomy, including our learning curve. METHODS: All consecutive 49 patients undergoing subxiphoid single-port thymectomy between August 2014 and September 2020 were reviewed retrospectively. RESULTS: We analyzed data of 49 patients (27 males and 22 females) with a median age of 58 years (range 49-68). Two patients presented postoperative complications. The conversion to a different approach was required in four cases. The median follow-up time was 17 months (range 3-35) and locoregional recurrence was observed in one patient. There were no intraoperative deaths and postoperative mortality. The operation time cumulative summation learning curve analysis revealed that the curves descended from the 24th case. CONCLUSIONS: The subxiphoid single-port approach for thymectomy is a safe and feasible modality with few complications.

We report the rare two cases of cardiac tamponade due to ruptured cystic teratoma. In both cases, a chest computed tomography scan showed large cystic mass with large amount of pericardial effusion. Transthoracic echocardiogram revealed cardiac tamponade physiology. En bloc resection of the mass was performed and pathologic examination showed mature cystic teratoma. The postoperative course of patients was uneventful. A cystic mediastinal teratoma should be considered in the differential diagnosis of pericardial effusion.
RESUMO
This report describes a case of successful repair of bronchoesophageal fistula through uniportal video-assisted thoracoscopic surgery. A 79-year-old female patient presented with persistent cough and aspiration pneumonia. Chest computed tomography and esophagography showed a bronchoesophageal fistula at right side wall of mid to lower esophagus. Esophagogastroduodenoscopy confirmed a fistula in the esophageal diverticulum. Surgical treatment was planned. The operation was performed through uniportal video-assisted thoracoscopic surgery. The patient was discharged 6 days postoperatively without any complication. No recurrence has been observed during 3 months follow-up in the outpatient clinic to date.

RESUMO
Infected pulmonary cyst could be misdiagnosed as empyema thoracis. Here, we report an infected pulmonary cyst in a middle-aged male patient. This report could serve as a reminder for differential diagnosis of infected pulmonary cyst, for which surgical approach would be more safe and effective method.
RESUMO
We report a case of a 28-year-old female who presented with a solid mass lesion in the right middle lobe (RML). A chest computed tomography (CT) scan showed a 3.5 cm sized round and solid mass between the medial and lateral segment of the RML. The patient underwent a percutaneous lung biopsy with CT scan guidance and pathological examination showed pulmonary sclerosing pneumocytoma. RML lobectomy was performed for definitive treatment. Here, we describe this rare lung disease which presented as a large homogeneous lesion. Pulmonary sclerosing pneumocytoma should be considered in the differential diagnosis of solitary lung tumor, even if the patient is young.

Even if the patient is young or female, a primary pulmonary diffuse large B-cell lymphoma could be considered as a differential diagnosis of multifocal consolidation in the lung.
RESUMO
We report a case of a 56-year-old man with persistent right upper lobe cavitary mass. A chest computed tomography scan showed about 4-cm-sized mass with internal low attenuation and peripheral enhancement in right upper lobe apical segment. The lesion size increased over 1 month. Right upper lobectomy was performed with the intention to treat the lesion. Pathological examination showed primary pulmonary undifferentiated pleomorphic sarcoma. We describe this rare lung disease to remind that primary pulmonary undifferentiated pleomorphic sarcoma could be the differential diagnosis of pulmonary cavitary mass lesions.

BACKGROUND: Uniportal video-assisted thoracoscopic surgery (VATS) anatomical lung resection has become widely accepted for its favorable outcomes with regard to pain. However, oncological outcomes, especially mid- or long-term outcomes, are still lacking. The objective of this study was to present our eight-year experience of uniportal VATS anatomical lung resection, including mid-term oncological outcomes. METHODS: All consecutive patients undergoing uniportal VATS anatomical lung resection between June 2012 and February 2020 were reviewed retrospectively. RESULTS: We analyzed data of 170 patients (100 male and 70 female), with a median age of 67 years. The median follow-up time was 21 months (range 11-41). The DFS of the entire cohort was 66.3 months. Stage-correlated DFS was 73.1 months for stage I, 42.6 months for stage II, 30.6 months for stage III and 12.5 months for stage IV. The OS of the entire court was 67 months. Stage-correlated OS was 75.6 months for stage I, 50.2 months for stage II, 31.7 months for stage III and 12.5 months for stage IV. CONCLUSIONS: Uniportal VATS anatomical lung resection for lung cancer can be performed with satisfactory mid-term histology- and stage-related outcomes, which is consistent with prior results of traditional VATS or thoracotomy.

This study was about a 70-year-old man with progressive dysphagia. Esophagogastroduodenoscopy showed a 1.2-cm circumferential ulcerative mass at the level of 23 cm from the upper incisors in the upper esophagus. The mass was first diagnosed as a poorly differentiated squamous cell carcinoma. McKeown esophagogastrectomy was performed with intention to treat the lesion. The pathological examination showed an esophageal neuroendocrine carcinoma that was mixed with squamous cell carcinoma component. In this report, we present a unique case of the extremely rare esophageal neoplasm, an esophageal neuroendocrine carcinoma with squamous cell carcinoma component.

This case was about a 71-year-old man presented to our clinic for an anterior mediastinal mass found on routine chest computed tomography (CT). CT scan showed a lobulating contoured mass in the anterior mediastinum. A preliminary diagnosis was thymoma. The patient underwent subxiphoid uniportal video-assisted thoracoscopic surgery for the extended thymectomy and complete excision of the tumour. The pathological examination showed a micronodular thymoma with lymphoid stroma (MTWLS). In conclusion, this report described an extremely rare tumour, MTWLS, and MTWLS might be considered in the differential diagnosis of mediastinal tumour, especially thymoma.
RESUMO
This report was about a 60-year-old asymptomatic female patient who presented to our clinic with an anterior mediastinal mass found on routine chest computed tomography (CT). Chest CT revealed an irregular poorly enhanced anterior mediastinal mass which showed signs of infiltration to adjacent structures with sparse calcifications. The preliminary diagnosis was thymic carcinoma. The patient underwent extended thymectomy via median sternotomy and complete excision of the tumor. A small draining vein to the left brachiocephalic vein and phleboliths were identified in the tumor. A definitive diagnosis was made of mediastinal venolymphatic malformation (VLM). The patient had an uneventful clinical course and was discharged without further complication. This report highlights that it is possible to misdiagnose mediastinal VLM as thymic carcinoma and could serve as a useful reminder to physicians in the future.

This case was about a 21-year-old man with recurrent and persistent hemoptysis. Chest computed tomography scan showed a right-sided pulmonary artery agenesis and associated hypertrophic change of right side bronchial arteries. Thoracic aortogram revealed abnormal collateral arteries supplying the right lung. Minor hemoptysis continued even after endovascular embolization of collateral vessels was performed. Right pneumonectomy was performed and the patient was treated successfully. Physicians should be aware that unilateral pulmonary artery agenesis could be a source of hemoptysis and pneumonectomy may be the best treatment.
