Whether gastrectomy with D2 lymphadenectomy improves survival of patients with advanced gastric cancer (AGC) remains controversial. Few studies have described the pathological features of AGC with metastatic suprapancreatic lymph nodes (LN), which are the target of D2 lymphadenectomy. This study therefore aims to clarify the prognosis and clinical(More)
BACKGROUND AND AIM We have focused on sodium alginate (SA) solution as a potential submucosal injection material for endoscopic submucosal dissection (ESD). A previous SA solution had high viscosity and problems such as difficult handling. After its properties were adjusted, SA solution was examined in vitro and its clinical safety was evaluated. METHODS(More)
BACKGROUND Histones play important roles in both host defenses and inflammation related to microbial infection. A peptide mimotope (SSV) was identified from a novel histone H1 monoclonal antibody (16G9 mAb) that was shown to inhibit the mixed lymphocyte reaction. In the present study, an anti-SSV producing hybridoma was established. We investigated the(More)
Endoscopic surgery is one of minimally invasive medical treatments, which reduces both physical and mental burdens of a patient than conventional abdominal operations. At present, a variety of training environments for endoscopic surgery, such as a dry box, a virtual reality (VR) simulator, and an animal experiment have been prepared to cultivate certifying(More)
OBJECTIVE Although pre-operative chemoradiation therapy for advanced lower rectal cancer is a controversial treatment modality, it is increasingly used in combination with surgery. Few studies have considered the combination of chemoradiation therapy followed by laparoscopic surgery for locally advanced lower rectal cancer; therefore, this study aimed to(More)
INTRODUCTION We recently observed an increased incidence of severe enterocolitis following laparoscopic low anterior resection (LAR) in some patients with stage II/III rectal cancer. This study aimed to examine the influence of laparoscopic LAR on postoperative enterocolitis compared with open LAR for Stage II/III rectal cancer. METHODS From April 2002 to(More)
A 56-year-old man with advanced esophageal carcinoma and lymph node swelling of abdomen (cStage III) underwent neoadjuvant chemotherapy (NAC) with 5-FU/CDDP. The side effect was stomatitis of grade 2. Primary tumor and lymph node swelling revealed remarkable effectiveness after 2 courses of NAC. Esophageal carcinoma was not found by endoscopy. Reduction of(More)
At present, some training tools for endoscopic surgery have been commercialized such as box simulator and virtual training simulator. These training tools enable a trainee to practice various operation without any risks of a patient and have been utilized by unskilled surgeons in medical institutions. However, more effective training environments have been(More)
Secretory immunoglobulin A (s-IgA) plays an important role in both gut and systemic immunity. This study aimed to investigate the production of s-IgA resulting from a CO2 pneumoperitoneum compared with a laparotomy. Using enzyme-linked immunosorbent assays, s-IgA in stool, malondialdehyde (MDA), and Toll-like receptor 4 (TLR4) in the ileal tissue were(More)
