Purpose: An uncut Roux-en-Y gastrojejunostomy has been known to be effective in preventing bile reflux gastritis in the remnant stomach and the Roux stasis syndrome. Materials and Methods: To evaluate the usefulness of a totally laparoscopic uncut Roux-en-Y gastrojejunostomy (TLuRYGJ) after a distal gastrectomy, we reviewed the medical records of 19 consecutive patients that underwent a TLuRYGJ at our institution, and 11 consecutive patients who underwent a totally laparoscopic Billroth I gastrectomy (TLB-I) during the same period. Results: Postoperative gastrointestinal symptoms related to the postgastrectomy syndrome and the Visick classification at six months after surgery were not different in the two groups; however, there was no case of symptomatic bile reflux gastritis and only one case of delayed gastric empting, for which medication was required, in the TLuRYGJ group. The endoscopic findings of the remnant stomach for bile reflux gastritis at six months after surgery were better in the TLuRYGJ group than in the TLB-I group. Conclusion: A TLuRYGJ was found to be effective in preventing bile reflux gastritis and the Roux stasis syndrome.

Purpose : Radical gastrectomy is main treatment of gastric cancer. But the result is not satisfactory with surgery alone. Most of pattern of failure remain locoregional recurrence. To improve 5 year survival postoperative chemotherapy with or without radiotherapy has been used. We analyzed patients with stage III and IV stomach cancer who had radical operation and received postoperative radiation therapy combined with or without chemotherapy retrospectively. Material and Method : From March 1985 to June 1993, 68 patients treated with curative resection and received postoperative adiuvant radiotherapy with 36Gy or more were evaluated. Median age was 60 years(range 28-66 yrs) . Patients were followed from 3 to 133 months with median follow up of 48 months. Thirty seven patients had non signet ring adenocarcinoma, 29 signet ring cell, 2 other cell. Patients with stage IIIA, IIIB, IV disease were 19, 25 and 24 respectively Chemotherapy was given to all patients except two. Results : Five-year overall survival and disease-free survival rate were 36.6% and 33.6%, respectively. Prognostic factor affecting survival were assessed. High ratio of jnvolved/dissected Iymph node, signet ring histology showed Poor Prognosis with statistical significance. Presence of residual tumor after surgery, stageIV. split course of radiation therapy, age, number of involved Iymph node, number of Iymph node dissection and grade of tumor affected survival without statistical significance, Type of chemotherapy did not affect survival. Recurrence was documented in 34 patients. High recurrence was seen in omentum and peritoneum with 23.5%, and remnant stomach, anastomosis site, A-loop and I-loop had also high recurrence with 13.2%. In field locoregional recurrence was 20.7% and total distant metastases were 39.7%. Total intraabdominal failure was 47.1% and extraabdominal failure was 13.2%. Treatment toxicity was considered to be acceptable. 22.1% of patients had grade 3 and only 1 patient had grade 4 leukopenia. Six Patients(8.8%) had weigh loss more than 10%. Conclusion : Treatment toxicity was acceptable with combined treatment with chemotherapy and radiotherapy. Locoregional recurrence was relatively low compared to distant failure with addition of irradiation. Peritoneal and omental seeding was high Five-rear surival was increased with combined modality. Radiation may eradicate minimal residual disease and improve survival, To evaluate role of radiation Prospective randomized study employing chemotherapy alone and chemotherapy plus radiation is necessary. Futhermore to reduce intraabdominal failure, role of intraabdominal chemotherapy in addition to combined chemotherapy plus radiation has to be explored.

Purpose : Although local recurrence rates of stomach cancer after radiocal surgery have been reported in the range of $30-70\%$, the role of postoperative adjuvant therapy has not been established. We report the result of radiotherapy in resected stomach cancer with positive surgical margin to elucidate the role of postoperative radiotherapy. Materials and Methods : From June 1991 to August 1996, twenty five patients with positive surgical margins after radical gastrectomy were treated with postoperative radiotherapy and chemotherapy. Median dose of radiation was 55.8Gy and the range was 44.6-59.4Gy. Second cycle of chemotherapy was delivered concurrently with radiation and total number of six cycles were delivered. Twenty three had adenocarcinoma and the other two had leiornyosarcoma. The numbers of patients with stage I B, II, III A, III B, and IV were 1, 2, 11, 10 and 1 respectively. Positive margins at distal end of the stomach were in 17 patients and proximal in 5. The other three patients had positive margin at the sites of adjacent organ invasion Minimum and median follow-up periods were 12 months and 18 months, respectively, Results : Twenty-four of 25 patients received prescribed radiation dose and RTOG grade 3 toxicity of UGI tract was observed in 3, all of which were weight loss more than $15\%$ of their pretreatment weight. But hematemesis. melena, intestinal obstruction or grade 4 toxicity were not found. Locoregional failure within the radiation field was observed in 7 patients, and distant metastasis in 10 patients. Sites of locoregional recurrences involve anastomosis/remnant stomach in 3, tumor bed/duodenal stump in 3, regional lymph node in 1 patient Peritoneal seeding occurred in 6, liver metastases months and median disease free survival time was 26 months. Stages andradiation dose were not significant prognostic factors for locoregional in 2, and distant nodes in 2 patients. Four year disease specificsurvival rate was $40\%$ and disease free survival was $48\%$. Median survival was 35 failures. Conculsion : Although all patients in this study had positive surgical margins, locoregional failure rate was $28\%$, and 4 year disease specific survival rate was $40\%$. Considering small number of patients and relatively short follow-up period, it is not certain that postoperative radiotherapy lowered locoregional recurrences. but we could find a Possibility of the role of postoperative radiotherapy in Patients with high risk factors.
