Conventional techniques for laparoscopic-assisted colectomy (LAC) require abdominal minilaparotomy for extraction of the specimen. Abdominal wound complications often increase the invasiveness of LAC. To decrease the incidence of wound complications, natural orifice specimen extraction (NOSE) has been reported. However, only a few devices that allow smooth(More)
A case of early gastric cancer, limited to submucosal layer, which was manifested as cerebral metastasis is presented herein. A 47-year-old man was admitted to Nagaoka Chuo General Hospital with convulsions and a disturbance in consciousness, where a computed tomography (CT) scan revealed a cerebral tumor in the left temporal lobe.

Natural orifice specimen extraction (NOSE) has been developed as a means of decreasing the incidence of surgical wound complications. However, NOSE performed using a conventional multiport technique has been reported previously. The current authors performed totally laparoscopic anterior resection with transvaginal specimen extraction (TVSE) using the(More)
We aimed to examine the safety and antitumor effects of a combination of S-1 and paclitaxel in patients with unresectable or recurrent gastric cancer in a phase I/II setting. The study was designed as a phase I/II clinical trial. In phase I portion, the dose of paclitaxel was escalated to estimate the maximum-tolerated dose (MTD) and recommended dose (RD)(More)
Gastrointestinal stromal tumors (GISTs) developing in the colon are rare, accounting for <5 % of all GISTs. There are few data on the clinical efficacy of tyrosine kinase inhibitors in colonic GISTs. We report here on an 80-year-old male patient with advanced GIST of the transverse colon. The patient underwent palliative resection of the primary tumor(More)
A seventy-eight year-old man with esophageal small cell carcinoma was reported. He was treated with chemotherapy of 5-FU and Cisplatin combined with radiotherapy. After 3 Courses of chemotherapy, the tumor almost disappeared. A biopsy specimen revealed moderate dysplasia but did not show residue of small cell carcinoma. The patient had lived with no(More)
Spontaneous perforation of the extrahepatic bile duct is rare. We herein report the case of an 80-year-old woman who underwent emergency laparotomy for bile peritonitis due to a spontaneous perforation of the common bile duct. A 2-mm perforation was found in the posterior wall of the choledochus, and its wall was paper-thin. Three stones, 2 mm in diameter,(More)
We have experienced successful treatment of a multiple hepatic metastasis of rectal cancer with combination chemotherapy. The patient is a 57-year-old male with bowel obstruction accompanied by rectal cancer (SE, N3, P1, H3, M (-) stage IV) who underwent a Hartmann operation with D3 lymph node dissection on July 6, 2000. The histopathological findings(More)
Hemodynamic study was carried out in 53 preoperative cirrhotic patients with portal hypertension and the postoperative prognosis was evaluated. In 16 cases of these patients, cardiovascular responsiveness to cold stress and 60 degrees head up tilt was measured using pneumoplethysmography and Swan-Ganz catheter. In comparison with the controls, cirrhotic(More)
