Abstract: Objective   To investigate the difference of surgical effect of exclusion,simple continuous suture and circular suture suspension in TAPP for the treatment of false hernia sac in patients with direct inguinal hernia. Method   From May 2020 to May 2022,120 patients diagnosed with direct inguinal hernia and treated with TAPP in our hospital were retrospectively.The  false hernia sacs were divided into three groups according to different methods of treatment patients treated with false hernia sac exclusion were included in group A,those treated with simple continuous suture were included in group B,and those treated with circular suture suspension were included in group C.There were 40 patients in each group.The perioperative indicators (operation time,intraoperative blood loss,postoperative hospital stay,hospitalization cost) and postoperative effects (chronic pain,seroma,incision or mesh infection,foreign body traction feeling) were compared among the three groups. Results   All 120 patients successfully completed TAPP surgery.There was no significant difference in general condition,intraoperative blood loss,postoperative hospital stay,wound or mesh infection and chronic pain among the three groups (P>0.05).The operation time of group B and C was longer than that of group A,and the incidence of seroma was significantly lower than that of group A,the difference was statistically significant (P<0.05).The incidence of foreign body traction in group A and group C was lower than that in group B,and the difference was statistically significant (P<0.05).The hospitalization cost of group B and group C was lower than that of group A,with statistically significant difference (P<0.05). Conclusion   In clinical practice,direct hernia and false hernia sac often need to be treated.In direct hernia TAPP operation,simple continuous suture method and circular suture suspension method have the effect of improving the condition of the false hernia sac,but in terms of economy and postoperative effect,the circular suture suspension method can benefit patients more.
