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)
BACKGROUND Laparoscopic surgery for gastric cancer is technically feasible, but it is not widely accepted because it has not been evaluated from the standpoint of oncologic outcome. We conducted a retrospective, multicenter study of a large series of patients in Japan to evaluate the short- and long-term outcomes of laparoscopic gastrectomy for early(More)
BACKGROUND Although several studies compare surgical results of laparoscopic and open colonic resections, there is no study of laparoscopic gastrectomy compared with open gastrectomy. HYPOTHESIS When compared with conventional open gastrectomy, laparoscopy-assisted Billroth I gastrectomy is less invasive in patients with early-stage gastric cancer. (More)
OBJECTIVE To evaluate the quality of life of patients who had undergone laparoscopy-assisted Billroth I gastrectomy (LAG) for cure of cancer. SUMMARY BACKGROUND DATA In 1994, the authors reported the first case of LAG for early gastric cancer, and this approach quickly has been adopted by Japanese surgeons. However, little is known about the subjective(More)
Because of the increased incidence of early gastric cancer in Japan, minimally invasive laparoscopic approaches to gastric malignancies have been under development since 1991. Laparoscopic local resection of the stomach, i.e., laparoscopic wedge resection (LWR) and intragastric mucosal resection (IGMR), is used to treat mucosal cancer without lymph node(More)
Since 1991, laparoscopic surgery has been adopted for the treatment of gastric cancer, and it has been performed worldwide, especially in Japan and Korea. We reviewed the English-language literature to clarify the current status of and problems associated with laparoscopic gastrectomy with lymph node dissection as treatment for gastric cancer. In Japan,(More)
Background: Studies of lymph node micrometastases in patients with colorectal cancer have ignored the prognostic significance of the number and level of lymph node micrometastases. The aim of this study was to clarify the prognostic significance of the status of lymph node micrometastases in histologically node-negative colorectal cancer. Methods: We used(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)
The efficacy and safety outcomes of laparoscopy-assisted distal gastrectomy (LADG) with D2 lymph node dissection for locally advanced gastric cancer remain unclear. Therefore, we conducted a randomized, controlled phase II trial to confirm the feasibility of LADG in terms of technical safety, and short-term surgical outcomes were investigated. Eligibility(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)
