Because of advancement of medical treatment, surgical management of gastric or duodenal ulcer was indicated for treatment of perforation, massive hemorrhage and obstruction. The distal gastrectomy including ulcer was known as principle method of duodenal ulcer obstruction, but actually many surgeons have performed only bypass surgery for the difficulty of formation of duodenal stump. In our case, 61-year-old male with repetitive duodenal ulcer obstruction transferred with obstruction due to deformities and inflammations of duodenal ulcer. We had performed totally laparoscopic distal gastrectomy with ROUX-EN-Y reconstruction using the clear visibility of laparoscopy and fine dissections of harmonic scalpel. The patient started soft diet on postoperative day 5 and discharged on postoperative day 8. He returned to work after discharging immediately.

PURPOSE: To evaluate the necessity for additional surgical treatment after Endoscopic Mucosal Resection (EMR) and Endoscopic Submucosal Dissection (ESD), we analyzed the pathologic results of patients who underwent surgical treatment. METHODS: 140 consecutive patients underwent additional surgical treatment after EMR/ESD with en bloc resection between April 2005 and November 2009 at ASAN Medical Center. Additional surgical treatments were undergone for following conditions such as incomplete dissection (involvement of margin), undifferentiated-type histology (> or =2 cm) and submucosal cancer. RESULTS: One patient with deep margin involvement displayed advanced gastric cancer after gastrectomy. Three of 74 patients with clear resection margin were confirmed to have residual cancer at ESD site and 2 of 3 patients displayed advanced gastric cancer after surgery. In univariate analysis for metastasis of lymph node, deep submucosal invasion (over sm2 or 500microm) and the presence of lymphovascular invasion showed significant differences for lymph node metastasis. Especially, lymphovascular invasion was an important predictive factor for lymph node metastasis in multivariate analysis. In analysis for residual cancer, lateral margin involvement and large tumor (>3 cm) were risk factors. And, only lateral margin involvement showed significant risk in multivariate analysis. CONCLUSION: Although EMR/ESD were fully accomplished for resection margin, gastrectomy and lymph node dissection were positively necessary for patients with deepsubmucosal invasion (over sm2 or 500microm) and the presence of lymphovascular invasion to eliminate the possibility of residual cancer or more advanced gastric cancer or metastatic lymph nodes.

PURPOSE: The aim of this study was to determine the prognostic factors and the significance of metastatectomy for Krukenberg's tumors of gastric origin. MATERIALS AND METHODS: Among the patient who underwent gastric surgery from 1992 through 2005, 90 female patients with Krukenberg's tumors of gastric origin were identified. We retrospectively reviewed the clinicopathologic characteristics, prognostic factors, and treatments for primary gastric cancer. We also investigated the prognostic risk factors for the onset of metachronous Krukenberg's tumors and the survival time of patients who underwent an operation for metachronous Krukenberg's tumors. RESULTS: The presence of a synchronous Krukenberg's tumor (mean survival time=17.6 months, P<0.01), peritoneal seeding (14.5 months, P<0.01), and non-curative resection (15.1 months, P<0.01), were statistically significant prognostic factors for survival time in female patients with gastric cancer. The stage of primary gastric cancer (P=0.049) and lymph node metastasis (P=0.011) were statistically significant risk factors for recurrence time of a metachronous Krukenberg's tumor. In the metachronous Krukenberg's tumor group (n=53), the mean survival time of the metastatectomy group (n=46, 43.2 months, P=0.012) was longer than that in the chemotherapy or conservative treatment groups (n=7 and 24 months, respectively). Metastatectomy, presense or abscence of residual tumor and extent of residual tumor were significant prognostic factors for survival time in female patients with metachronous Krukenberg's tumor of gastric origin. CONCLUSIONS: A close observation and evaluation with ultrasound or computed tomography is necessary in female patients with advanced gastric cancer to detect a metachronous Krukenberg's tumor as soon as possible. The surgeon must operate more aggressively in patients with metachronous Krukenberg's tumors.

PURPOSE: To evaluate the effectiveness of laparoscopic assisted total gastrectomy (LATG), we compared its early surgical outcomes with those of conventional open total gastrectomy (OTG) in patients who were diagnosed as having early gastric cancer preoperatively. METHODS: We retrospectively analyzed early surgical outcomes in 190 consecutive patients who underwent total gastrectomy for early gastric cancer between January 2009 to April 2010. The patients were divided into those who underwent LATG and those who underwent OTG. Their early surgical outcomes were analyzed to evaluate the effectiveness of LATG. RESULTS: There was no significant difference in postoperative complication rates (P = 0.291). But in the analysis of other early surgical outcomes, we found that LATG could improve time to first flatus (P < 0.001), time to commencement of soft diet (P = 0.034), administration of analgesics (P = 0.024), pain score (Numeric Rating Scale), and hospital discharge (P = 0.045). CONCLUSION: Although LATG didn't show better results for postoperative complications than those of OTG, LATG contributes to the improvement of early surgical outcomes, including bowel movement, pain score and hospital discharge. Therefore, we suggest that LATG could be a method to improve early surgical outcomes in patients who need total gastrectomy.

In order to know the possibility of utilizing the sister chromatid exchanges as an index which could evaliiate the effect of organic solvents on Lhe health in industrial workers, the authors Studied the effects of the inductivity of sister chromatid exchanges in peripheral lymphocyces from 90 female workers espoxed to organic solvents .and 20 lion-exposed female workers. The results obtained were as follows: 1. The frequency of sister chromatid exchanges in peripheral iympnocytes from 90 female workers exposed to organic solvents was significantly increased in comparison with 20 coatiol subiect. 2. The frequency of sister chromatid exchanges was significantly Increased in the workers who were employed in the manufacture of plastic materials than the other manufactures. 3. There were no significant differences in the frequency of sister chrornatid exchanges by carriera of the exposed workers. 4. The correlation between the frequency of sister chromatid exchanges and urinary hippuric acid was significant with the coefficient of 0.5902 showing Y=1.867X+15.188 in which Y indicate the frequency of sister chromatid exchanges per cell and X indicate the urinary hippuric acid concentration by g/l.
