Background: Laparoscopy-assisted gastrectomy requires a lot of disposable products. So we compared the cost between laparoscopy-assisted gastrectomy and open surgery.Patients and methods: For comparison we used five cases each of open distal gastrectomy (ODG), laparoscopy-assisted distal gastrectomy (LADG), open total gastrectomy (OTG) and laparoscopy assisted total gastrectomy (LATG). In this study, we defined the profit of gastrectomy as below and we used the list price for all products. Profit of gastrectomy=Fee for gastrectomy-(Costs of all single use products-Demandable fee for single-use products)Results: Mean profits of ODG and LADG were 278,756.2 yen and 190,292.8 yen. The difference was 88,463.4 yen. Mean profits of OTG and LATG were 395,922.6 yen and 330,653.6 yen. The difference was 65,269 yen. Mean hospital charges, mean length of hospital stay, mean hospital charges per day of ODG, LADG, OTG and LATG were 1,390,464 yen, 21.4 days, 65,140.0 yen and 1,484,254.0 yen, 18.8 days, 80,805.4 yen and 1,956,664.0 yen, 24.4 days, 82,397.1 yen and 1,686,936.0 yen, 18.4 days, 91,894.8 yen, respectively.Conclusion: The turnover of laparoscopic gastrectomy was higher than open gastrectomy, but, the profit was lower because of high costs of disposable products. Hospital charges were not higher but the charge per day was higher because of a shorter hospital stay.

Caudolateral curvilinear osteophyte (CCO), an osteophyte at the site of joint capsule attachment on the caudal aspect of the femoral neck, has been advocated as a radiographic criterion for coxofemoral subluxation. The correlation between the presence of CCO on radiographs (radiographic-CCO), the size of the CCO (CCO index) on three-dimensional computed tomographic (CT) images, and hip evaluation using transverse CT images was assessed in 22 Border Collies. CCOs were detected on the radiographs and CT images of 32% and 100% femurs, respectively. The CCO index correlated significantly with radiographic-CCO, but a large CCO index did not necessarily imply that the CCO was visible on radiographs. Hence, radiographic-CCO findings should be used cautiously in hip evaluation of Border Collies.
