To determine size and shape discrepancy between the bone of Korean women and the prostheses in total knee arthroplasty, the height(antero-posterior length) and width(medio-lateral length) of the distal femur and the proximal tibia were measured at the bone resection level for 104 knees of 62 female patients who underwent primary total knee arthroplasty and compared with the same parameters of the total knee prostheses designed by five different companies. On the condition that the height of the prostheses matched with each cases of the bone were optimal, the difference in the width was evaluated, and the criteria of the discrepancy were overhang if the width of the prosthesis was larger than bone, optimal if width of the prosthesis was same or smaller and difference was within 5 mm, and down-size if smaller and difference was over Smm. In femoral prostheses, 34.6% of all were optimal, 13.1%, overhang and 52.3%, down-size. In tibial prosthesis, 54.1% of all were optimal, 13.9%, overhang and 32%, down-size. In conclusion, although further investigation for clinical application is needed, there were discrepancies in size and shape between the femur and tibia of Korean women and total knee prostheses and improvement in design should be considered.

BACKGROUND/AIMS: Colorectal adenomas that are > or =10 mm have villous histology or high-grade dysplasia, or that are associated with > or =3 adenomas are considered high-risk for metachronous advanced neoplasia. We evaluated the cumulative incidence of metachronous advanced neoplasia according to the total number of high-risk findings detected on baseline colonoscopy. METHODS: This was a retrospective cohort study performed in 862 patients who underwent removal of colorectal adenomas between 2005 and 2009. At least one surveillance colonoscopy had been conducted at Konkuk University Medical Center, Seoul, Korea. RESULTS: The cumulative incidence of metachronous advanced neoplasia in patients with 0, 1, 2, and 3-4 high-risk findings at 1 year were 0.7%, 1.3%, 2.8%, and 8.0%; at 3 years, those were 5.9%, 11.9%, 15.5%, and 24.7%; and at 5 years, those were 8.5%, 18.7%, 26.3%, and 37.2%, respectively. In a multivariate model, the risk of metachronous advanced neoplasia was significantly higher for the multiple high-risk findings group when compared with the 0 high-risk findings group (1 high-risk (+): hazard ratio, 1.86 [95% confidence interval, 1.00-3.44]; 2 high-risk (+): 1.84 [0.88-3.84]; and 3-4 high-risk (+): 3.29 [1.54-7.01]; ptrend=0.020). CONCLUSIONS: The presence of overlapping multiple high-risk findings was associated with an increased risk of advanced neoplasia during surveillance.

PURPOSE: Prognosis of primary gastric cancer invading neighboring organs is very poor. However, with en bloc resection, a relatively favorable prognosis can be expected even in patients with such advanced cancer. But there has been controversy on the effectiveness of gastrectomy combined with en bloc resection of the invaded organs, and we conducted this study to evaluate the prognostic effects as well as the outcome of the combined resection. MATERIALS AND METHODS: Among 2,603 who underwent gastrectomy due to gastric carcinoma from January 1987 to December 1994 at the Department of Surgery, Yonsei University College of Medicine, 157 patients (6.0%) in whom curative combined resections of grossly invaded adjacent organs (cT4) were perfonned entered this study. Any case with distant metastasis was excluded. Comparisons and multivariate analysis between the invasion (pT3) group and the non-invasion (pT4) group were made for age, sex, tumor size, location, Borrmann type, depth of invasion, lymph node metastasis, histologic type and 5-year survival rate. RESULTS: One-organ combined resection was done in 60 (38.2%) patients; Two-organ, in 80 (51.0%) patients; and three-organ, in 17 (10.8%) patients. Most commonly combined organ was distal pancreas and transverse colon was the next. Histologic confirmation of invasion was made in 40.9%. 157 patients with T4 were divided into pT3 or pT4. Significant differences were found in type of operation, location of tumor, and TNM staging. Postoperative complications of combined resection were observed in 48 cases (30.6%) and the wound infection was the most frequent one. There were only 2 cases (1.3%) of immediate postoperative mortality in the combined group, and the causes of death were pulmonary complication and acute renal failure. Five-year survival rate (5-YSR) of pT3 group was 43.0% and that of pT4 was 26.2%. In comparison of 5-YSR according to TNM stages, no significant difference was found between pT3 and pT4 (45.0% vs. 66.7% in IIIa; 25.4% vs. 18.4% in IV). No difference of 5-YSR was observed in the groups categorized according to the number of resected organs. The comparison of 5-YSR between the 157 curatively-combined cases and the 63 palliatively-combined cases showed a significant difference (35.6% vs. 4.2%, p=0.000). Multivariate analysis showed that lymph node metastasis and microscopic tumor invasion served as significant parametets. CONCLUSION: En bloc combined resection of adjacent invaded organs along with systematic lymph node dissection would be beneficial to gastric cancer patients with neighboring organ invasion.
