Clinical significance of chorda arteriae umbilicalis in laparoscopic transabdominal preperitoneal hernia repair / 局解手术学杂志

ABSTRACT

Objective To investigate the clinical significance of the chorda arteriae umbilicalis in laparoscopic transabdominal preperi-toneal(TAPP)hernia repair.Methods The clinical data of 60 patients with inguinal hernia admitted to Xinrui Hospital in Xinwu District of Wuxi City from June 2019 to June 2022 were analyzed,and the patients were randomly divided into two groups according to whether the chorda arteriae umbilicalis was used as a marker during operation.Both the control group and the observation group were operated according to the routine procedure.The observation group exposed the chorda arteriae umbilicalis,which was used as a reference to precisely free the surgical plane and gap to complete the parietalization of spermatic cord,meanwhile,the angle formed by the intersection of the deferens and umbilical artery cord was used to assist in fixing the patch.The operation time,time of parietalization of spermatic cord,hospital stay,bladder surface bleeding volume,removal rate of hernial sac,the occurrence of postoperative complications and recurrence of patients were compared between the two groups.Results There was no significant difference in the operation time,removal rate of hernial sac,hospital stay,recurrence rate or the incidence of postoperative complications such as chronic pain,uroschesis of patients between the two groups(P>0.05).The time of parietalization of spermatic cord,bladder surface bleeding volume,and incidence of seroma of patients in the observation group were shorter/lower than those in the control group,the differences were statistically significant(P<0.05).Conclusion The chorda arteriae umbilicalis has a constant morphology and relatively fixed anatomical position and alignment.The chorda arteriae umbilicalis can be used as a reference and guiding mark,especially when the anatomical layer is dense and unclear or strayed into the layer in TAPP hernia repair,whihc can guide to operate at the correct layer,standardize the parietalization of spermatic cord,reduce bleeding and vice-damage,and also assist the fixation of the patch and prevent the displacement of the patch.
