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 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 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)
The genotype Blastocystis hominis is highly polymorphic. Therefore, a genetic marker would be a powerful tool for the identification or classification of B. hominis subtypes and could be used as a means to resolve the transmission route or origin of the parasite. To this end, 32 B. hominis isolates were collected from patients and/or staff members of two(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)
BACKGROUND Since 1995, we have been performing pancreatoduodenectomy with regional and para-aortic lymph node dissection for patients with distal bile duct cancer. Prognostic indicators after extended lymphadenectomy have not been fully understood. HYPOTHESIS Pancreatoduodenectomy with extended lymphadenectomy and adjuvant chemotherapy is the treatment of(More)
To assess the risk of variceal bleeding, endoscopic findings in 172 patients with esophageal varices were classified based on the "General Rules for Recording Endoscopic Findings on Esophageal Varices" prepared by the Japanese Research Society for Portal Hypertension. Among the factor which enabled an accurate prediction of bleeding were the red wale(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)
