Abstract
To study tubal adhesion, tubal patency and histologic difference under light, electronic microcopy in a site of anastomosis, authors performed three anastomosis surgery in rabbit fallopian tube;1-layer and 2-layer anastomosis in splint-not-used group(group 1) and in splint-used group(group 2) and laser anastomosis in splint-used group(group 3). 10 rabbits were used in each group, therefore the total number of experimental rabbits in 3 groups were 30. The results were as follows; 1. The degree of gross adhesion in group II was significantly high as compared with other groups but there was no difference between left and right tube in the degree of adh- esion in each group(Table 1). 2. The incidence of tubal patency in group I was significantly high(89%) as compared with group I(44%). Especially, the incidence of tubal patency in group III was significantly high(100%) but there was no difference between left and right tube in incidence of tubal patency in each group. 3. Inflammatory cell infiltration appeared in each group on optical microscopic examin- ation. Especially, fibrosis and inflammatory cell infiltration appeared more in group II but there was no statistically significant difference. And there was no significant difference between left and right tube in each group. 4. Transmission electron microscopic examination of group I, as compared with normal control group, showed increase of microvilli and secretory granules and decrease in size of epithelial cell. Epithelial cell was morphologically transformed but maintained the original structure comparatively. TEM examination of group II, as compared with normal control group, showed decrease of microvilli and secretory granules and flattening of epithelial cell. It showed that epithelial cell vanished in it's original structure. TEM examination of group III, as compared with normal control group, showed decrease of microvilli and increase of secretory granules and morphological transformation of epithelial cell. Group III showed the resemblence to normal control group. From the above results, in reversal tuboplasty and tubal factor infertility, it is consi- dered that simple splint-used anastomosis or splint-used anastomosis with Nd-YAG laser will improve the successful rate of tubal anastomosis.
