[Three-dimensional and 4K Three-dimensional Uniportal Video-assisted Thoracoscopic Surgery for Mediastinal and Chest Wall Disease During Respiratory Surgery].

Uniportal video-assisted thoracoscopic surgery (VATS) lobectomy has recently been used with increasing frequency by thoracoscopic surgeons, even in Japan. However, few reports have previously described uniportal VATS for mediastinal and chest wall disease. From April 2008 to December 2022, 159 patients were treated for mediastinal and chest wall disease.

[Palmar Hyperhidrosis Associated with the Azygos Lobe].

A 66-year-old man visited our department because of palmar hyperhidrosis. Computed tomography had revealed division of the right upper lobe by a fissure and the azygos vein, and the presence of an azygos lobe had been diagnosed. Endoscopic thoracic sympathectomy (resection of T3 ganglion) was performed.

[Three-dimensional (3D)-Video-assisted Thoracic Surgery (VATS) and Robot-assisted Thoracic Surgery(RATS)].

We firstly introduced a 3-dimensional system [3D-video-assisted thoracic surgery (VATS)] to the world in 2012, and have since performed 3D-VATS-lobectomy. From March 2012 to October 2019, 224 patients for lung cancer were treated by 3D-VATS. Since then, we have added resection of mediastinal tumors and 3D-uniportal-VATS.

CT findings of a displaced left upper division bronchus in adults: its importance for performing safe left pulmonary surgery.

Purpose: The aim of this study was to describe the CT findings of a displaced left upper division bronchus (DLUDB) in adults.

Materials And Methods: Ten patients with DLUDB were identified. The following CT features were assessed: origin of the DLUDB; distance between the origin of the DLUDB and the origin of the left upper lobe (LUL) bronchus; height of the origin of the DLUDB against the left pulmonary artery (LPA); difference of the main bronchial length; ventilated segment; course of the left pulmonary artery against the DLUDB; and presence of an accessory fissure or other anomalies.

[Single-incision thoracoscopic surgery( SITS) for mediastinal disease].

The use of single-incision laparoscopic surgery is spreading widely, even in Japan, however, in the field of thoracic surgery, there exist no previous reports on the use of the Wound retractor system in single-incision thoracoscopic surgery (SITS) for mediastinal disease. We herein describe the 1st cases of video-assisted SITS of the mediastinum. Fifteen patients (5 males, 10 females) with mediastinal disease underwent SITS.

Carcinosarcoma of the duodenum: Report of a case.

This report describes a case of carcinosarcoma of the duodenum. Carcinosarcoma of the duodenum is a very rare tumor. A 72-year-old man was referred to the hospital because of appetite loss.

Simultaneous occurrence of partial anomalous pulmonary venous return and major bronchial anomaly: computed tomography findings in 5 adult patients.

Objective: The objective of this study was to describe the computed tomography (CT) findings of 5 adult patients with a combination of partial anomalous pulmonary venous return (PAPVR) and major bronchial anomaly.

Methods: A computerized search of the radiological database records of 4886 consecutive patients who underwent chest CT from April 2005 to May 2007 described 2 patients with a combination of PAPVR and tracheal bronchus (TB). Three additional patients with a combination of PAPVR and TB or accessory cardiac bronchus (ACB) were obtained by reviewing the CT images of the patients initially diagnosed as having PAPVR, TB, or ACB at our institution during the same period.

Feasibility trial of adjuvant chemotherapy with paclitaxel and carboplatin after surgical resection in Japanese patients with non-small cell lung cancer: report of the Lung Oncology Group in Kyushu (LOGIK) protocol 0501.

Objectives: The present study was designed to determine whether adjuvant chemotherapy with paclitaxel (TXL) and carboplatin (CBDCA) after surgical resection is feasible in Japanese patients with non-small cell lung cancer (NSCLC) in a multiinstitutional trial.

Methods: From August 2005 to March 2006, 34 patients received the following regimen: TXL (175 mg/m2) and CBDCA (AUC = 5) on day 1, every 3 weeks. The primary endpoint of this trial was the completion rate of four cycles.

[A case of long-term survival of postoperative brain metastasis of small cell lung cancer effectively treated with chemotherapy, whole brain radiotherapy and stereotactic radiosurgery].

A 63-year-old woman underwent right upper lobectomy for small cell carcinoma. She received a total of 2 courses of carboplatin and etoposide infusion as adjuvant therapy. One year after the operation, because of elevated serum Pro GRP levels and a metastatic brain tumor revealed by CT, 4 courses of IP therapy (irinotecan 60 mg/m(2), day 1, 8, 15 and cisplatin 60 mg/m(2), day 1, every 4 weeks) and whole brain radiotherapy (2 Gy f, 5 f/week, total 40 Gy) were given.

[A case of postoperative multiple pulmonary metastases of non-small-cell lung cancer successfully treated with S-1].

We report a case of postoperative multiple pulmonary metastases of NSCLC successfully treated with S-1. A 72-year-old man underwent rt. lower lobectomy + ND 2 a by VATS.

Comparison of surgical outcome using the prediction scoring system of E-PASS for thoracic surgery.

Objective: The purpose of this study was to determine if our predictive scoring system, E-PASS, can estimate the surgical outcome.

Methods: We conducted a multicenter cohort study for 3 years in four national hospitals. A consecutive series of 731 patients who underwent elective thoracic operations were analyzed.

[Minimally invasive surgery for primary hyperhidrosis].

Nine hundred twenty-three thoracoscopic sympathectomies for primary hyperhidrosis were performd in 462 patients (180 men, 282 women). Mean age was 29.2 (11-61) years.

Novel approach for a pulmonary bronchogenic cyst: a report of a case.

We present a case of a bronchogenic pulmonary cyst in a 48-year-old patient. We performed [corrected] mucoclasis using argon laser photocoagulation following resection of mucosa, closure of some drainage bronchus, and covering of the inner surface by the intrapulmonary bronchogenic cyst with an [corrected] absorbable vicryl mesh. At [corrected] 4-year [corrected] follow-up, the patient had no signs of recurrence.

A randomized trial of adjuvant chemotherapy with uracil-tegafur for adenocarcinoma of the lung.

Background: In a previous phase 3 trial of adjuvant chemotherapy after resection of non-small-cell lung cancer, a combination of uracil and tegafur (often referred to as UFT) taken orally was shown to prolong survival. A subgroup analysis disclosed that most patients who benefited had pathological stage I adenocarcinoma.

Methods: We randomly assigned patients with completely resected pathological stage I adenocarcinoma of the lung to receive either oral uracil-tegafur (250 mg of tegafur per square meter of body-surface area per day) for two years or no treatment.

Lung adenocarcinoma with coexisting pulmonary cryptococcoma.

A 73-year-old female was referred to our hospital in June 2000 for the evaluation of an abnormal shadow in the left upper lobe of her lung and two other shadows in the left lower lobe. A computed tomography examination revealed an ill-defined tumor with ground glass opacity in the left upper division segment, suggesting a primary lung adenocarcinoma, and two well-defined nodules in the left lower lobe, suggesting metastatic carcinomas. A transbronchial lung biopsy of the tumor in the upper division segment confirmed the presence of an adenocarcinoma but failed to provide a histological diagnosis for the nodules in the lower lobe.
