A 67-year-old male was admitted to our hospital for the treatment of pyothorax due to bronchopleural fistula at right main bronchus after pneumonectomy for lung cancer( squamous cell carcinoma, pathological stageⅢB). After tube drainage and fenestration, we performed operation to close large diameter fistula, that was almost fully opened stump of the right main bronchus. Omental flap was sutured roughly to the fistula with four stiches and inserted into the bronchus lumen, and covered with latissimus dorsi muscle flap to fix omental pedicle flap and additionally performed thoracoplasty to close the residual space of the pleural cavity.

The patient was diagnosed with intralobar pulmonary sequestration and scheduled for an operation. During the surgery, after resection of the aberrant artery, indocyanine green was intravenously injected, and the border between normal lung and sequestrated lung was clearly identified by an infrared thoracoscope.

Although she had undergone a radical mastectomy for right breast cancer 28 years previously, the nodule was suspected to be either metastatic lymphoma or primary lung cancer and thoracoscopic surgery was planned to perform. Since the intraoperative frozen section diagnosis was adenocarcinoma, right lower lobectomy and systemic lymph node dissection were performed.

Five months later, he was pointed out a massive right pleural effusion. Being diagnosed with pleuroperitoneal communication, he was referred to our department for surgery.

Methods: Using a multi-institutional database, we performed a retrospective chart review to identify all patients who had undergone complete resection of stage I-III EGFR-mutated lung adenocarcinoma at 11 acute care hospitals between 2009 and 2016 and had received first-line EGFR-TKI treatment for postoperative recurrence. Adverse events, progression-free survival (PFS) and overall survival (OS) were investigated.

Pleuroperitoneal communication is one of the complications for continuous ambulatory peritoneal dialysis. Communication sites, such as defects or bleb-like lesions, are found in the diaphragm, but it is sometimes difficult to detect these sites. We combined the infrared thoracoscopy and negative pressure technique to detect communication sites.

He underwent extrapleural pneumonectomy with reconstruction of the pericardium and diaphragm using elongated polytetrafluoroethylene patches, followed by postoperative chemotherapy and chest wall irradiation. One year later, he was hospitalized because of a right empyema caused by Escherichia coli infection.

Three months after surgery, he was diagnosed with pleural empyema due to bronchopleural fistula and open window thoracostomy was performed. Since we could not decrease the dead space and the amount of pleural effusion, we introduced negative pressure wound therapy (NPWT).

He had a past history of subarachnoid hemorrhage. He was diagnosed with pulmonary arteriovenous malformation (PAVM) and recommended early treatment, but he didnot accept immediate surgical treatment.

Case Presentation: A 38-year-old man was referred to our hospital with chest pain.
A congenital complete pericardial defect is a rare and often asymptomatic condition that may be diagnosed intraoperatively. While performing lung lobectomy in patients with this condition, surgeons must exercise more caution than with standard lobectomies. Additional points of consideration include the use of surgical instruments to ensure a clear operative field, vascular treatment for pulmonary veins, confirmation of the phrenic nerve location, and determination of the need to repair the pericardial defect.

Objectives: In endoscopic surgery, fragile tissues may be damaged by the application of excessive force. Thus, we developed novel endoscopic forceps with a simple force-limiting mechanism.
Methods: The novel forceps were constructed with a leaf spring, and the spring thickness determines grasping pressure.
Background: Costal coaptation pins made of poly-L-lactide (PLA) are clinically available for fixing surgically divided ribs. However, the clinical results of such rib fixation have not been completely satisfactory. We aimed to develop a new rib coaptation socket system and explore its clinical applicability.

We previously developed a biocompatible polypropylene frame artificial trachea, but it lacked the strength and flexibility of the native trachea. In contrast, nitinol may provide these physical characteristics.

To provide a sufficient field of view during these procedures, surgeons must manipulate the lung using conventional devices such as cotton-tipped medical applicators and graspers. However, medical applicators are unable to pull on the target lung lobes, and graspers can damage the lung tissue.

Micro-RFID markers with nickel-titanium coils were designed to be placed from subsegmental bronchi to the peripheral parenchyma. In this preclinical study, thoracoscopic subsegmentectomy of a canine pseudotumor model was performed to demonstrate the feasibility and three-dimensional positional accuracy of the system.

Thoracoscopic partial pulmonary resection for small peripheral nodules without using a stapler has been introduced to our hospital. After partial resection was performed with electrocautery, two different methods of surface sealing were used: a coagulation method (C method) with Soft Coagulation alone, and a coagulation-suturing method (CS method) with Soft Coagulation combined with continuous suturing. The clinical outcomes of the two methods were retrospectively compared in this study.

These procedures involve the insertion of specialized devices into the thoracic cavity via access ports. However, conventional devices such as cotton-tipped applicators and graspers can limit the field of view and injure the fragile lung tissue.

This report presents the results of preclinical studies of our novel localizing technique in a canine model.
Methods: To evaluate functional placement, three types of tags [Group A, tag alone (n = 18); Group B, tag + resin anchor (n = 15); and Group C, tag + NiTi coil anchor (n = 15)] were bronchoscopically placed in subpleural areas and subsegmental bronchi via our new delivery device; tags were examined radiographically on days 0-7 and day 14.

Anastomosis in bronchoplasty is usually performed using interrupted sutures, which are considered safe, reliable, and secure. However, placing interrupted sutures can be complex and time-consuming. There have been recent reports of continuous suturing using standard suture materials in bronchoplasty.

However, cardiopulmonary exercise testing (CPET), which is recommended for patients with poor pulmonary function, is available only in limited institutions. We investigated the possibility of 6-min walk test (6MWT) as a substitute of maximum oxygen consumption test (VO(2)max) on preoperative physiologic assessment for lung cancer surgery.

A 53-year-old Japanese woman was referred to our hospital for pure ground glass opacity (GGO) in the left upper lung on computed tomography. 18F-fluorodeoxyglucose positron emission tomography revealed no abnormal uptake in the lesion. After 4 months of follow-up, we strongly suspected the lesion to be a bronchioloalveolar carcinoma and decided to perform a surgery for diagnosis.
