BACKGROUND A pulmonary metastasectomy for colorectal carcinoma is a generally accepted procedure, although several prognostic predictors have been reported. The aim of this study is to define the patients who benefit from pulmonary metastasectomy for colorectal carcinoma. METHODS Retrospective survival analysis was performed using 128 patients who(More)
OBJECTIVE Indications for surgical intervention for very limited small cell lung cancer have not yet been determined. The objective of this study is to determine whether resection followed by cisplatin and etoposide is feasible. METHODS From September 1991 through December 1996, 62 patients with completely resected small cell lung cancer who were less(More)
OBJECTIVE Although malignant pleural effusion or dissemination is regarded as T4 per TNM classification of lung cancer, the prognostic significance in staging of pleural lavage cytologic examination remains undetermined. The purpose of this study was to clarify the utility of pleural lavage cytologic staging as a prognostic factor in patients with non-small(More)
OBJECTIVES Pleural lavage cytology is the microscopic study of cells obtained from saline instilled into and retrieved from the chest during surgery for non-small-cell lung cancer. The aims of this study were to collate multi-institutional individual patient data for meta-analysis to determine independence as a prognostic marker and to characterize the(More)
We treated a 15-year-old patient with spontaneous pneumothorax associated with Swyer-James syndrome using video-assisted thoracoscopic surgery (VATS). Thoracic computed tomography showed hyperlucent areas in the bilateral lungs. Due to major air leakage continuing for a week, we conducted VATS bullectomy. Because the opposite lung suffered hypoplasia,(More)
New techniques for laparoscopic cholecystectomy (LC) that reduce the number of trocars or use very thin instruments have been devised with the goal of further minimizing surgical invasiveness. We performed two-trocar LC using an original new technique in 70 consecutive patients. A 10-mm trocar and a 5-mm trocar were inserted in the subumbilical and(More)
BACKGROUND The prognosis of patients with resected non-small cell lung cancer without carcinomatous pleuritis whose intrapleural cancer cells were detected by means of a cytologic examination of pleural lavage fluid obtained immediately after a thoracotomy has been reported to be poor. METHODS The Japan Clinical Oncology Group conducted a phase III trial(More)
OBJECTIVE Primary tracheal cancer is considered to be relatively rare. Its epidemiology, therapeutic strategy and prognosis are not well understood. METHODS We retrospectively investigated the clinicopathological aspects of 20 patients with primary tracheal cancer. RESULTS Patients included 11 men and nine women with a mean age of 57.3 years. There were(More)
We report herein the case of a 76-year-old man for whom an invasive mucin-producing tumor of the pancreas (MPTP) was successfully treated by surgery. A cystic lesion of the pancreas had been found by computed tomography (CT) 9 years earlier, 2 years following which suction drainage for left pyothorax had been carried out. A pancreatic cyst fistula to the(More)
We report 2 cases of thymomatous myasthenia gravis associated with postoperative crisis and medicated with steroid therapy using prednisolone without primary dose escalation. Two women, a 38 years old and the other 64 years old, underwent extended thymectomy under the diagnosis of myasthenia gravis associated with invasive thymoma. Bulbar symptoms in both(More)
