To explore the difference between laparoscopic transabdominalpreperitoneal hernia repair (TAPP) and laparoscopic totally extra-peritoneal repair (TEP) in the treatment of inguinal hernia and the incidence of postoperative seroma, and to analyze the causes of seroma and preventive treatment measures.

A retrospective analysis was conducted on 45 TAPP patients with inguinal hernia (TAPP group) and 30 TEP patients with inguinal hernia (TEP group) treated in the hospital of Shunyi District from January 2017 to June 2018. Perioperative indicators such as operation time, postoperative hospitalization time, hospitalization cost, as well as postoperative incidence of seromas in the two groups were monitored respectively.

Compared with TEP group, TAPP group reduced the operative time [(55.50±4.25) minutes vs (65.36±6.52) minutes, P<0.05].However, the hospitalization cost of TAPP group was higher than that of TEP group [(14 500±700) yuan vs (12 500±500) yuan, P<0.05]. Postoperative hospitalization days in the TAPP group and TEP group were (3.25±1.34) and (3.55±1.20) days, respectively, with no statistically significant difference (P>0.05). The incidence of postoperative seroma in TAPPgroup was lower than that in the TEP group (P<0.05).

Compared with traditional open inguinal hernia repair, both TAPP and TEP have significant therapeutic effects, but TAPP has a relatively high cost of hospitalization. Compared with TEP, TAPP can reduce the incidence of postoperative seroma. We believe that reasonable patient selection and accurate intraoperative operation may be the key to reduce the incidence of postoperative seroma.
