Relatively Safer and Efficient Pleurodesis With 50% DW for Very Elderly Patients With Secondary Spontaneous Pneumothorax: Report of 2 Cases.

I report 2 cases of pleurodesis with 50% dextrose water (DW) in very elderly patients with secondary spontaneous pneumothorax. In both cases, a chest computed tomography scan showed a large pneumothorax with emphysema and multiple bullae. Patients were expected not to tolerate surgical treatment, considering their old age and underlying pulmonary disease.

Iatrogenic Pneumothorax Misdiagnosed as Spontaneous Pneumothorax.

Pigtail catheter drainage is commonly performed for pleural effusion drainage. It should be noted that if the catheter is not connected to a closed system such as a chest bottle, outside air may enter; causing iatrogenic pneumothorax.

Lucky case of pinch-off syndrome combined with colloid adenocarcinoma of the lung.

We report a case of a colloid adenocarcinoma in the left lower lobe in a 59-year-old female. The fractured chemoport catheter fragment, which was inserted 10 years ago for gastric cancer chemotherapy, was embedded in left superior segmental pulmonary artery. The patient underwent left lower lobectomy with resection margins and all lymph nodes free of tumor through uniportal video assisted thoracic surgery.

Mediastinal Hemangioma Mimicking Thymic Tumour.

Mediastinal hemangioma is a rare cause of an anterior mediastinal mass. Careful imaging review, including evaluation for a potential feeding vessel, should be performed prior to potential surgical resection to reduce the risk of complications such as massive bleeding.

The Efficacy of PET/CT Scan in CT-Guided Needle Biopsy of Large Lung Mass.

In CT-guided needle biopsy of large lung mass, false-negative error could occur due to the necrotic portion of lung mass. If a biopsy is performed on a metabolically active lesion with reference to PET/CT scan, it would help to increase the chances of achieving an accurate diagnosis.

Non-Specific Chest Pain-Possibility of Finding Suggestive of Hidden Pleural Metastasis.

Non-specific chest pain may suggest important implications such as pleural metastasis. Therefore, active diagnostic procedures such as thoracoscopy and surgical biopsy should be considered in patients with lung mass without obvious pleural involvement who complain of non-specific persistent chest pain, even in the absence of specific findings on imaging studies and the association of pain with trauma.

Pleurodesis With 50% Dextrose for Old Patient With Secondary Spontaneous Pneumothorax: Relatively Safe and Efficient Method.

We recommend that even in old patients with severe COPD, who could not tolerate chemical pleurodesis, pleurodesis with 50% dextrose should be considered since it is a relatively safe and efficient method.

The feasibility of thoracoscopic-guided intercostal nerve block during uniportal video-assisted thoracoscopic lobectomy of the lung.

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.

A pilot study of intraoperative intercostal nerve block during uniportal thoracoscopic wedge resection of the lung.

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.

Transbronchial Lung Cryobiopsy for Diagnosing Interstitial Lung Disease: A Retrospective Single-Center Experience.

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.

Subxiphoid single-port thymectomy without CO insufflation: Experience of a single center.

Background: The subxiphoid single-port approach for thymectomy has advantages compared with conventional lateral transthoracic approaches. Most of centers use CO 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 CO insufflation using a retractor and steel wire.

Isolated chest wall tuberculosis in immunocompetent patients.

Chest computed tomography scan demonstrated inflammatory lesion in and around the right sixth rib costochondral junction.

The Learning Curves of Uniportal Video-Assisted Thoracoscopic Surgery Lobectomy: A Single Center Experience.

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. 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.

Subxiphoid single-port thymectomy: six-year experience of a single center.

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.

Successful Repair of Bronchoesophageal Fistula Through Uniportal Video-Assisted Thoracoscopic Surgery.

This report describes a case of successful repair of bronchoesophageal fistula through uniportal video-assisted thoracoscopic surgery.
