【摘要】 目的　观察小型猪皮下组织抽吸后的组织学变化。方法　采用注射器和直径为 2mm的抽吸管行白色五指山成年小型猪背部皮下吸脂术。于术前及术后不同时间点分别取吸脂区和对照区皮下脂肪组织标本进行肉眼和 (或 )组织切片观察。结果　抽吸侧皮下脂肪厚度明显变薄 ,约为对照侧的 5 3 5 %。术区脂肪组织中只在真皮下、浅筋膜隔旁和肌膜表面等处瘢痕形成较多且消褪缓慢 ,术后 6～ 8个月脂肪小叶结构清楚。抽吸后皮下脂肪细胞的大小、形态与对照部位比较无显著意义。结论　吸脂术可明显减少皮下脂肪的厚度。抽吸时避免损伤皮肤和脂肪下肌层可减少术后瘢痕形成。采用细小的抽吸管可进行浅层脂肪抽吸。更多还原

【Abstract】 Objective To study the postliposuction histologic alterations of adipose tissue in Mini-pigs. Methods\ Five Wuzhishan adult Mini pigs were suctioned with syringe assisted liposuction using a suction needle of 2 mm in diameter. The subcutaneous adipose tissues on both operated and controlled non operated areas were collected from one week to eight months after operation and all samples were measured and observed macroscopically and microscopically. Results\ The thickness of subcutaneous adipose tissues at the operated sites is thinner than the controlled sites. There was no significant difference in adipocyte morphology between the two kinds of samples. The structure of fat tissue recovered normally during 6～8 months after liposuction. Conclusion\ Liposuction is an effective operation to eliminate the subcutaneous adipose tissue and the structure of subcutaneous adipose tissue is completely normal in 6～8 months after the operation.;更多还原
