BACKGROUND: To date, a laparoscopic gastrectomy has been performed by a small number of surgeons around the world, but the laparoscopic approach has been extended to Billroth I and a total gastrectomy. To evaluate the validity of the procedure, we present the results of six patients who underwent a gastrectomy using a laparoscopic technique. METHODS: First, two patients had a totally intra-abdominal laparoscopic B-II gastrectomy, and one of two also had a bilateral truncal vagotomy. The rest had a laparoscopic-assisted gastrectomy. One patient had concurrently an open reduction and an internal fixation with a K-wire for a patellar fracture. Indications were (a) gastric outlet obstruction due to peptic ulcer disease in five patients and (b) duodenal ulcer bleeding in one patient. RESULTS: Except for one patient who had stump leakage, which was solved by conservative therapy, there were no complications or operative mortality. The operating time and the cost were less for the patients who had their operations later in the series and who had laparoscopic-assisted operation. CONCLUSIONS: These forms of laparoscopic gastric surgery for patients with complications of peptic ulcer disease may be useful from the standpoint of minimal access, rapid recovery, less pain, and good cosmesis.

PURPOSE: Galectin 3 is a beta-galactoside binding protein that is involved in various biological processes such as cell adhesion, migration, cell growth, tumor progression and metastasis. Although the precise acting mechanisms of Galectin 3 are unclear, it have been reported that the expression of Galectin 3 may related to tumor progression and metastasis. We investigated the immunohistochemical expression of Galectin 3 in 57 cases of benign and malignant breast neoplasm to evaluate the relation of a Galectin 3 expression to malignancy of breast neoplasm and the acting mechanism of Galectin 3. METHODS: Twenty fibroadenomas, 7 intraductal papillomas, 10 intraductal carcinomas and 20 invasive ductal carcinomas were studied. Immunostaining of Galectin 3 was evaluated in comparison with that of the internal controls, and the intensity of immunostaining was semiquantitatively graded on an intensity scale of 0 to 3. RESULTS: The normal ductal epithelium of the breast showed strong immunoreactivity with an intensity 2 to 3. The staining gradually and significantly decreased in accordance with the histopathological type and tumor progression from a fibroadenoma, intraductal papilloma, ductal carcinoma in situ and invasive ductal carcinoma (P<0.001). In particular, the expression of galection-3 was prominently decreased in invasive ductal carcinoma. CONCLUSION: The galectin-3 expression pattern suggests that progression from benign breast tumor to malignant breast tumor leads to a reduced expression of galectin-3.

PURPOSE: Various prognostic indicators have been identified for mammary carcinomas, but the issue of their significance remains unsettled. The prognostic impact of c-erb B2, Ki-67 and topoisomerase II alpha expression was investigated in relation to prognostic factors for carcinomas of the breast and to the tumor cell growth fraction. METHODS: One hundred eighteen cases of invasive mammary carcinoma were investigated by immunohistochemical staining for c-erb B2, topoisomerase II alpha, and Ki-67. Clinicopathologic parameters were compared with the expression pattern and incidence of c-erb B2, topoisomerase II alpha and Ki- 67 in invasive mammary carcinoma. RESULTS: C-erb B2 showed significant correlation with topoisomerase II alpha (P<0.05), but others were not significant. Topoisomerase II alpha and Ki-67 index closely paralleled each other, indicating that both reflect the proliferate activity of tumor cells and were associated with high nuclear and histological grade, ER and PR expression (P<0.05). CONCLUSION: These results indicate that ki-67 and topoisomerase II alpha proteins might play a role in tumor progression of breast carcinoma. The Ki-67 and topoisomerase II alpha index may be proliferate factors of breast cancer. In addition, the increase expression of Ki-67 and topoisomerase II alpha and hormone receptor were closely correlated each other, and could be used as factors suggesting poor prognosis in breast carcinoma.

The main complications associated endoscopic mucosal resection are bleeding and perforation and the rate of complication is increasing in larger size of mucosal resection. We used a new method of endoscopic clipping technique for ligation on the large mucosal defect after endoscopic mucosal resection. A 53-year-old female patient visited our hospital because of epigastric pain. Endoscopic examination revealed a type IIa EGC(early gastric cancer) below angle. The endoscopic mucosal resection was performed and the size of resected specimen was 2.7x2.5cm. The mucosal defect was ligated with 6 hemoclips(Olympus, MD-850) after approximation of both resected margins by grasping forceps(Olympus, FG-4L). Follow up endoscopic examination revealed good quality of ulcer healing. The Endoscopic clipping technique might also be useful for treatment of minor perforation.

PURPOSE: We evaluated the validity of laparoscopy-assisted distal gastrectomy (LADG) with systemic lymphadenectomy for early gastric cancer in elderly patients compared with younger patients. METHODS: Seventeen elderly patients (aged 70 years or more) and 113 younger patients who underwent LADG for early gastric cancer between May 1998 and July 2004, at the department of Surgery, Dong-A University Medical Center, were studied. Postoperative outcomes were compared. RESULTS: In elderly patients, co-morbidity was more common than in younger ones (P=0.0220) and postoperative complication rate was more common, too (P=0.0480). Operation time (P=0.7301), time to first flatus (P=0.4766), postoperative hospital stay (P=0.4860), mortality (P=0.2453), were similar in these two groups. CONCLUSION: Because LADG with systemic lymphadenectomy in elderly patients has more co-morbidity and complications than younger ones, great cares should be given to treat co-morbidity preoperatively and prevent complications during operation and postoperative period in elderly patients.

BACKGROUND: The prognosis following surgery for gastric cancer has been markedly improved as a result of early diagnosis and advancements both in operative techniques and perioperative management. However, gastrointestinal surgery in the presence of hepatic cirrhosis has shown high operative morbidity and mortality due to severe perioperative complications, such as bleeding, lymphorrhea, anastomosis leakage, hepatic failure, fluid retention, acute renal failure and multiple organ failure. Recently, the frequency of gastric cancer involving liver cirrhosis has been increasing, especially early gastric cancer cases. METHODS: From June 1995 to December 1997, a total of 410 patients with gastric cancer were treated surgically. Among them, 9 cases with liver cirrhosis underwent gastric resection. RESULTS: Three major postoperative complications occurred in 2 patient, anastomosis leakage in one, and bleeding in both. CONCLUSIONS: The purposes of this study were to assess the causes of complications and to decide the appropriate operation type for improving the prognosis for these patients with liver cirrhosis.

While intussusception can occur at any age, the disease is most often seen in children and no etiologic factor can be seen in most cases of childhood intussusception. In contrast, the adult intussusception is rare and usually has an identifiable causes such as benign tumor, malignant tumor, sarcoma, Meckel's diverticulum and congenital anomaly. Especially, adult intussusception due to primary malignant lymphoma of small intestine is rare clinical condition. Here, we describe the case of a 49-year-old male patient with ileo-ileo-colic intussusception due to primary malignant lymphoma of the small intestine. The clinical, radiographic and pathologic findings are described with brief review of the literature.
