超声刀甲状腺大部分切除术的效果评估

目的探讨使用超声刀降低甲状腺大部分切除术患者术中损伤的效果。方法将92例接受甲状腺大部分切除术治疗的患者随机分为超声刀组和电刀组,超声刀组44例、电刀组48例。电刀组使用传统电刀进行手术,超声刀组使用超声刀进行手术。对比两组患者术中资料、术后恢复速度和术后并发症发生率。应用SPSS 19.0软件包进行数据处理,术中资料指标及术后资料指标等计量资料呈正态分布,以(x珋±s)表示,采用t检验;术后并发症发生率等计数资料采用χ2检验。P0.05为差异具有统计学意义。结果超声刀组手术时间(48.8±15.6)min、术中出血量(19.6±14.4)ml、切口长度(4.3±1.1)cm、线结个数(2.2±1.7)个显著少于电刀组的(59.1±16.3)min、(31.9±19.7)ml、(5.6±1.6)cm、(7.4±2.3)个,两组比较差异有统计学意义(t=3.096,3.438,4.572,12.399,P0.01)。超声刀组术后引流量为(29.7±18.7)ml显著低于电刀组的(54.1±33.5)ml(t=4.359,P0.01)。并发症总发生率:超声刀组为20.5%(9/44),电刀组56.3%(27/48),两组间差异有统计学意义(χ2=13.700,P0.01)。结论使用超声刀进行甲状腺大部分切除术操作更为简便且术中损伤较小、具有临床应用价值。

Evaluation of subtotal thyroidectomy using ultrasound knife

Objective To evaluate the use of ultrasound knife in reducing operative injury in subtotal thyroidectomy . Methods A total of 92 patients who underwent subtotal thyroidectomy were randomly divided into two groups:ultrasonic knife group ( 44 patients ) and electrotome group ( 48 ) .Patients in the electrotome group were subjected to electrotome treatment , whereas those in the ultrasonic knife group were subjected to ultrasonic knife treatment .Operation data, postoperative recovery , and complications were compared between the two groups .SPSS 19.0 software was used for data analysis .Intra-and post-operative data normally distributed were represented as mean ±SD and examined by Student’s t test.Complication rate was examined by the Chi-square test.P value <0.05 was considered statistically significant . Results The operation time (48.8 ±15.6) min, blood loss (19.6 ±14.4) mL, incision size (4.3 ±1.1) cm, and knot number (2.2 ±1.7) in the ultrasonic knife group were significantly less than those (59.1 ±16.3) min, (31.9 ±19.7) ml, (5.6 ±1.6) cm, and (7.4 ±2.3)] in the electrotome group (t=3.096, 3.438, 4.572, 12.399, P<0.01).The post-operative drainage volume in the harmonic scalpel group was (29.7 ±18.7) ml, which was significantly less than (54.1 ±33.5) ml in the electrotome group (t=4.359, P<0.01).The in incidence of complications in the ultrasonic knife group was 20.5%(9/44), which was significantly less than 56.3%(27/48) in the electrotome group (χ2 =13.700, P<0.01). Conclusion The use of ultrasonic knife in subtotal thyroidectomy is feasible with minimal invasion.
