Preoperative administration effect of metronidazole, ceftriaxone sodium and their combination on stenotic index of jejunal anastomotic segment of dogs / 대한수의학회지

The jejunum is the longest part of the small intestine and its lumen is mainly involved in the absorption of the nutrients. The present study was conducted to evaluate the effects of metronidazole, ceftriaxoine sodium and their combination on the stenotic index of the end to end jujunal anastomotic site. To accomplish this, 20 healthy stray dogs were subjected to end to end jejunal ansastmosis. Dogs in Group A (control) underwent jejunal anstomosis with no antibiotic prophylaxis, while those in Group B received surgery and metronidazole alone at 50 mg/kg, those in Group C received ceftriaxone sodium intravenously at 30 mg/kg body weight prior to surgery and dogs in Group D were given metronidazole in combination with ceftriaxone sodium at 50 mg/kg and 30 mg/kg, respectively, 2 h before surgical intervention. No significant difference (p > 0.05) in the stenotic index was observed at 14 days after jejunal anastomosis. These findings indicate that prophylactic administration of metronidazole and ceftriaxone sodium alone or in combination had no significant effect on the stenotic index of the jejunum.

Surgical Results of Encephaloduroarteriomyosynangiosis(EDAMS) for Moyamoya Desease

Moyamoya disease is a cerebrovascular disease of unknown etiology which leads to spontaneous occlusion of circle of Willis. Cerebral ischemic or hemorrhagic episodes occur as moyamoya disease progresses. To establish an efficient collateral circulation for the ischemic brain of this disease many surgical the therapeutic methods have been proposed. We analyzed the surgical results of encephaloduroarteriomyosynangiosis(EDAMS) and compared with that of direct bypass surgery, superfical temporal artery to middle ce rebral artery(STA-MCA) anastomosis to determine the efficacy of new indirect revascularization procedure, EDAMS, in the treatment of moyamoya disease. Twenty three patients with moyamoya disease who underwent revascularization procedure were included in this study. EDAMS was performed on 18 sides in 16 patients and STA-MCA anastomosis was done on 12 sides in 7 patients. Two patients underwent encephaloduroarteriosynangiosis(EDAS). The surgical results of EDAMS were excellent to good in 14 patients and fair in 2 patients. No statistical significance of the outcome was observed in comparision of EDAMS and STA-MCA anastomosis(p-value=0.471). Regardless of surgical procedures, outcome of child-onset moyamoya disease was found to be superior to those of adult-onset moyamoya disease(p-delete=0.024). In conclusion, EDAMS is considered to be one of the effective indirect revascularization methods to prevent the ischemic attack and establish the revascularization for moyamoya disease.
