BACKGROUND The application of laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer remains controversial among gastric surgeons. The purpose of this study was to compare LADG with open distal gastrectomy (ODG) regarding clinical outcome and postoperative parameters, including postoperative pain and pulmonary function. METHODS From(More)
PURPOSE Although risk factors for histologically overt lymph node metastasis in patients with early-stage colorectal cancer have been clarified, the risk factors for occult lymph node metastasis are not clear. This study was designed to clarify risk factors for lymph node metastasis, including occult metastasis, in patients with colorectal cancer invading(More)
OBJECTIVE A randomized controlled trial to confirm the non-inferiority of laparoscopic surgery to open surgery in terms of overall survival was conducted, and short-term surgical outcomes are demonstrated. BACKGROUND The efficacy and safety outcome of laparoscopic surgery for clinical stages II/III colon cancer undergoing Japanese D3 dissection are still(More)
To evaluate laparoscopy-assisted Billroth-I gastrectomy (LADG), we examined the outcome of its use over the last 10 years. From December 1991 to December 2001, 116 patients with early gastric cancer underwent LADG in the surgical department of Oita Medical University and Koga hospital by the same surgical staffs. An operation record and clinical sheets were(More)
Tumors in the upper one-third of the stomach has been increasing. Although the standard operation for proximal gastric cancer has been total gastrectomy, some have used proximal gastrectomy reconstructed by jejunum or gastric tube. The aim of this study was to evaluate the surgical results, hospital costs, and quality of life after gastrectomy for cancer. A(More)
There is no consensus as to the impact of lymph node micrometastasis on survival of patients with gastric cancer. The aim of this study was to clarify the prognostic significance of lymph node micrometastasis in patients with histologically node-negative gastric cancer Lymph nodes (n=2039) from 64 patients with histologically node-negative gastric cancer(More)
Laparoscopy-assisted distal gastrectomy (LAG) is gaining acceptance for treating early gastric cancer. However, the long-term quality of life after LAG for gastric cancer is unknown. This study compared the long-term quality of life after LAG versus open distal gastrectomy (ODG) for early gastric cancer. This study included 53 patients who underwent LAG and(More)
Little is known about the outcomes of laparoscopic wedge resection (LWR) in comparison with conventional open wedge resection (OWR) for gastric submucosal tumor. Outcomes of 21 patients who underwent LWR (n = 14) or OWR (n = 7) for gastric submucosal tumor between 1993 and 2004 were investigated. We compared the short-term and long-term operative results(More)
We previously reported that the one-step nucleic acid amplification (OSNA) assay provided a judgment performance for colorectal cancer equivalent to a 2-mm-interval histopathological examination of lymph nodes (concordance 97.1 %, n = 385 lymph nodes). In this prospective multicenter study, we uncovered an OSNA-assisted pathology to detect lymph node(More)
BACKGROUND A few studies have addressed the physiology related to a basic natural-orifice transluminal endoscopy surgery (NOTES) procedure, such as transgastric peritoneoscopy, but the physiologic impact of more complex NOTES procedures has not been previously examined. OBJECTIVE To evaluate the cardiopulmonary and immunologic effects of transvaginal(More)
