Abstract

BACKGROUND

Tissue liquefaction liposuction (TLL) deploys a novel energy source utilizing a stream of warmed, low-pressurized, and pulsed saline to extract fat tissue.

OBJECTIVES

Compare TLL to suction-assisted liposuction (SAL) to determine which device is more efficient for surgeons and provides better recovery for patients.

METHODS

Thirty-one adult female patients were followed prospectively in a contralateral study design comparing differences in bruising, swelling, tenderness, and incision appearance ratings between TLL and SAL procedures. Surgical efficiency and appearance of the lipoaspirate were also compared.

RESULTS

All 31 patients successfully completed the study. For TLL and SAL procedures, the average volumes of infusion (1.242 vs 1.276 L) and aspirated supernatant fat (704 vs 649 mL) were statistically similar. TLL median fat extraction rate was faster than SAL (35.6 vs 25 mL/min; P < 0.0001), and stroke rate was reduced in TLL vs SAL procedures (48 vs 120 strokes/min; P < 0.0001), and both were statistically significant. The mean total scores for bruising, swelling, treatment site tenderness, and incision appearance were lower, indicating improved patient recovery on the TLL side.

CONCLUSIONS

TLL and SAL techniques produced comparable volume of fat aspirate. TLL demonstrated a 42% faster fat extraction rate and a 68% reduction in arm movements needed to complete the procedure compared to SAL, both of these differences are statistically significant. The TLL side was noted to have reduced bruising and swelling and improved incision site appearance with less tenderness compared to the SAL side.

摘要

背景

组织液化吸脂术（TLL）采用一种新型能量源，利用温热、低压且脉冲式的生理盐水流来抽取脂肪组织。

目的

比较TLL与吸脂辅助抽脂术（SAL），以确定哪种设备对外科医生更高效，对患者恢复更好。

方法

采用对侧研究设计对31名成年女性患者进行前瞻性随访，比较TLL和SAL手术在瘀伤、肿胀、压痛和切口外观评分方面的差异。还比较了手术效率和抽脂物外观。

结果

所有31名患者均成功完成研究。对于TLL和SAL手术，平均输注量（1.242对1.276升）和吸出的上清脂肪量（704对649毫升）在统计学上相似。TLL的中位脂肪提取率比SAL快（35.6对25毫升/分钟；P<0.0001），且TLL手术的抽气速率比SAL降低（48对120次抽气/分钟；P<0.0001），两者均具有统计学意义。瘀伤、肿胀、治疗部位压痛和切口外观的平均总分较低，表明TLL侧患者恢复情况更好。
