探讨腹腔镜经腹腹膜前疝修补术（TAPP）中应用超声刀对减轻术后术区血清肿的效果。

回顾性分析2017年1-7月南方医科大学附属南海医院行TAPP治疗的腹股沟疝85例。根据手术器械的不同将患者分为超声刀组（n=35）和电凝钩组（n=50）。根据Morales提出的血清肿分类，比较2组患者术后血清肿的发生率。

85例患者术后通过门诊复诊及电话随访1年均未复发。其中超声刀组术后出现血清肿2例，发生率为5.71%；电凝钩组出现血清肿9例，发生率为18%，2组比较差异有统计学意义（P<0.05）。超声刀组没有出现Ⅲ型及以上的严重血清肿；电凝钩组发生Ⅲ型血清肿1例（2%），2组比较差异无统计学意义（P>0.05）。

TAPP术中应用超声刀进行操作，可以减少术后血清肿的总体发生率，但对Ⅲ型以上严重血清肿的发生率没有显著影响。

To investigate the effect of the ultrasonic scalpel on reducing postoperative seroma in laparoscopic transabdominal preperitoneal hernia repair (TAPP).

A retrospective analysis of 85 patients with inguinal hernia who underwent TAPP at the Affiliated Nanhai Hospital of Southern Medical University from January to July 2017 was conducted. Patients were divided into the ultrasonic scalpel group (n=35) and the coagulation hook group (n=50) according to the different surgical instruments. According to the classification proposed by Morales, the incidence of postoperative seroma was compared between the two groups.

No recurrence was found in 85 patients after surgery through outpatient follow-up and telephone follow-up for 1 year. Among the patients in the ultrasonic scalpel group, there were 2 patients with seroma after surgery, with an incidence of 5.71%. There were 9 cases of seroma in the coagulation hook group (18%), and the difference between the two groups was statistically significant (P<0.05). There was no severe seroma of type Ⅲ or above in the ultrasonic knife group. Type Ⅲ seroma occurred in 1 case (2%) in the coagulation hook group, and there was no significant difference between the two groups (P>0.05).

In TAPP, the application of an ultrasonic scalpel can effectively reduce the overall incidence of postoperative seroma. But, as to type III and more serious seroma, there is no significant difference .
