ABSTRACT: Postoperative ileus (POI) is one of the most common complications of gastrointestinal surgery. The present study was performed to evaluate the effects of glutamine administration on POI after gastric surgery in humans.
The subjects were 31 patients who underwent partial distal gastrectomy for gastric cancer and who were randomly assigned to one of two groups based on postoperative treatment: the glutamine group (3 g/day) and the control group. Manometric recording was done 12 days after surgery, and plasma glutamine concentrations were measured preoperatively and on postoperative day 12.
Motor activities of the duodenum in the glutamine group were significantly greater than those of the control group in the interdigestive state. The incidence of phase III motor activity (interdigestive migrating motor contractions) in the glutamine group was significantly higher than that in the control group (60 versus 19%). The glutamine group showed a significantly smaller decrease of plasma glutamine levels compared with the control group.
Glutamine could act as a motility-recovery agent after gastrectomy in humans.

ABSTRACT: Endoscopic submucosal dissection (ESD) is a safe, efficacious, and minimally invasive technique for superficial gastrointestinal neoplasms. However, the procedure is long, complex, and associated with higher complication rates. To overcome such limitations, the authors devised a double endoscopic intralumenal operation (DEILO) and assessed its efficacy and safety for superficial gastric neoplasms.
The DEILO procedure was performed for 31 gastric cancers. This novel technique is characterized by the use of two endoscopes, one for lifting lesions and the other for cutting them, inserted into the stomach simultaneously.
The DEILO technique was performed successfully, and en bloc resection was achieved for 29 (93.5%) of 31 patients. Histologically, curative resection was achieved for 26 lesions (83.8%). The mean operating time for DEILO was 34 min (range, 20-107 min). Two patients experienced postoperative hemorrhage, which was controlled endoscopically. Perforation occurred in two cases (6.4%), both of which were successfully treated nonsurgically.
The DEILO procedure appears to shorten the operating time for ESD, with comparable efficacy and complication rates.

ABSTRACT: In recent years, laparoscopic gastrectomy has been applied for the treatment of gastric cancer in Japan and Western countries. This report describes the short- and long-term results for patients with gastric cancer who underwent laparoscopically assisted total gastrectomy (LATG) with lymph node dissection.
From September 1999 to December 2007, 20 patients underwent LATG, and 18 underwent conventional open total gastrectomy (OTG) for upper and middle gastric cancer. The indications for LATG included depth of tumor invasion limited to the mucosa or submucosa and absence of lymph node metastases in preoperative examinations. The LATG and OTG procedures for gastric cancer were compared in terms of pathologic findings, operative outcome, complications, and survival.
No significant difference was found between LATG and OTG in terms of operation time (254 vs 248 min.), number of lymph nodes (26 vs 35), complication rate (25% vs 17%), or 5-year cumulative survival rate (95% vs 90.9%). Differences between LATG and OTG were found with regard to blood loss (299 vs 758 g) and postoperative hospitalization (19 vs 29 days).
For properly selected patients, laparoscopically assisted total gastrectomy can be a curative and minimally invasive treatment for early gastric cancer.

ABSTRACT: Gastric carcinoma patients with peritoneal dissemination have an extremely poor prognosis. Attempting to improve regional control and decrease the risk of complications related to hyperthermic chemotherapy, we applied a new treatment modality using a combination of gastrectomy with postoperative intraperitoneal hyperthermo-chemotherapy (PIHC) using Thermotron RF-8. The purpose of this study was to evaluate the feasibility of PIHC in advanced gastric carcinoma patients with peritoneal seeding.
Between March 2002 and April 2006, 20 gastric carcinoma patients with peritoneal dissemination were allocated to two groups in the patient's selection. The PIHC group (10 patients) received a 60-min PIHC with a cisplatin dose of 80 mg/m2 two weeks after surgery, and the control group (10 patients) received surgery alone. Thermotron RF-8 is a heating device that can raise temperatures in both superficial and deep-seated tumours using 8 MHz radiofrequency electromagnetic waves as a source of heat.
No patients in either group had life-threatening complications. The most frequent nonhaematologic toxicity (grade 3) was nausea. The one-, two-, and three-year cumulative survival rates for the PIHC group were 60%, 48%, and 36%, respectively, whereas those for the control group were 40%, 10%, and 0%, respectively. The survival rates for the PIHC group were significantly higher than those for the control group.
Although this study was conducted non-randomly with a small number of patients, the PIHC group had a higher survival rate and better prognosis compared with the control group.
