腹横肌的CT解剖学及其在腹横肌平面阻滞的临床意义

目的探讨腹横肌在不同人群腹壁层面的厚度变化及其在腹横肌平面阻滞的临床意义。 方法回顾性分析2021年1-12月济南市中心医院胃肠外一科60例住院患者的临床及CT资料。用CT影像LIS系统测量不同水平腹横肌和腹壁厚度，分析腹横肌和腹壁厚度及其影响因素。 结果脐水平和髂前上棘水平腹横肌厚度在不同体质量指数（BMI）、性别和年龄之间差异无统计学意义（P>0.05）；脐水平与髂前上棘水平腹壁厚度在不同性别、BMI之间差异均有统计学意义（P<0.05），在不同年龄之间差异无统计学意义（P>0.05）。 结论腹横肌厚度在不同人群腹壁层面相对恒定，对腹腔镜辅助腹横肌平面阻滞具有重要参考意义。

CT-based anatomical measurement of transversus abdominis and its clinical significance in transversus abdominis plane block

ObjectiveTo investigate the thickness variation of the transversus abdominis at the abdominal wall level in different populations and its clinical significance in the transversus abdominis plane block. MethodsThe clinical and CT data of 60 inpatients in the First Department of Gastrointestinal Surgery, Jinan Central Hospital from January to December 2021 were retrospectively analyzed. The thickness of transverse abdominis and abdominal wall at different levels were measured using CT image LIS system. The thickness of transverse abdominis and abdominal wall and their influencing factors were analyzed. ResultsThere was no significant difference in the thickness of the transversus abdominis at the level of the umbilicus and the anterior superior iliac spine between different body mass index (BMI), gender and age (P>0.05). There were significant differences in the thickness of the abdominal wall at the level of the umbilicus and the anterior superior iliac spine between different gender and BMI (P<0.05), but no significant differences between different ages (P>0.05). ConclusionThe thickness of the transversus abdominis is relatively constant at the abdominal wall level in different populations, which has important reference significance for laparoscopic-assisted transversus abdominis plane block.
