脐动脉索在腹腔镜经腹腹膜前疝修补术中的临床意义

Clinical significance of chorda arteriae umbilicalis in laparoscopic transabdominal preperitoneal hernia repair

目的 探讨脐动脉索在腹腔镜经腹腹膜前疝修补术(TAPP)中的临床意义。方法 回顾性分析2019年6月至2022年6月无锡市新吴区新瑞医院收治的60例腹股沟疝患者的临床资料,根据术中是否以脐动脉索为标志将患者分为2组。对照组和观察组均按常规操作步骤进行手术。观察组刻意显露脐动脉索,并以其为参照物精准游离手术平面与间隙,完成标准壁化,同时利用输精管与脐动脉索交汇所形成的夹角辅助固定补片。比较2组患者的手术时间、精索壁化时间、住院时间、膀胱表面出血量、疝囊完整剥离率、术后并发症发生及复发情况。结果 2组患者的手术时间、疝囊完整剥离率、住院时间、复发率及慢性疼痛、尿潴留等术后并发症发生率比较,差异无统计学意义(P>0.05)。观察组患者的精索壁化时间、膀胱表面出血量、血清肿发生率短/低于对照组,差异有统计学意义(P<0.05)。结论 脐动脉索形态恒定,解剖位置、走行相对固定。TAPP术中以脐动脉索作为参照、引导标志,尤其解剖层面致密不清或误入层面时,可指引术者在正确层面操作,规范精索壁化,减少出血、副损伤,且脐动脉索还可起到辅助补片固定,防止补片移位的作用。

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.
