To review the success rates for liposuction of lipomas in dogs, report early complications and medium-term outcomes and formulate recommendations on the most appropriate candidates for liposuction.
Retrospective study of 20 dogs with 76 lipomas diagnosed by cytology, in which dry liposuction was attempted. Case records were reviewed for number and size of the lipomas, efficacy of liposuction, frequency and types of complication and likelihood of recurrence.
Liposuction was successful in removing 73 of 76 lipomas (96%). Simple, encapsulated lipomas less than 15 cm in diameter were most easily removed, with minimal risk of complication. Giant lipomas contained fibrous trabeculae that hindered liposuction and resulted in poor fat retrieval. Giant lipomas were also associated with a high risk of bruising, haematoma and seroma, especially when inguinal in location. Regrowth was noted at follow-up between 9 and 36 months in 28% of lipomas.
Liposuction may be less invasive and more attractive to owners than conventional surgery for lipomas up to 15 cm in diameter. Liposuction is not recommended for infiltrative or giant inguinal lipomas. Regrowth can be expected in a high proportion of lipomas, which should be considered when choosing liposuction over conventional excision.
回顾犬脂肪瘤抽脂术的成功率，报告早期并发症和中期结果，并就抽脂术最合适的候选对象提出建议。
对20只经细胞学诊断患有76个脂肪瘤的犬进行回顾性研究，尝试进行干式抽脂。审查病例记录，了解脂肪瘤的数量和大小、抽脂术的疗效、并发症的频率和类型以及复发的可能性。
76个脂肪瘤中有73个（96%）抽脂成功。直径小于15厘米的简单、有包膜的脂肪瘤最容易切除，并发症风险最小。巨大脂肪瘤含有纤维小梁，阻碍抽脂并导致脂肪回收不佳。巨大脂肪瘤还与高风险的瘀伤、血肿和血清肿相关，尤其是位于腹股沟部位时。在9至36个月的随访中，28%的脂肪瘤出现了复发。
对于直径达15厘米的脂肪瘤，抽脂术可能比传统手术侵入性更小，对主人更具吸引力。不建议对浸润性或巨大腹股沟脂肪瘤进行抽脂术。预计高比例的脂肪瘤会复发，在选择抽脂术而非传统切除术时应考虑到这一点。
