摘要
目的 应用CT技术评价老年腹股沟疝患者的肌肉质量。方法 拟接受腹股沟疝手术、年龄在70~90岁的男性住院患者30例为研究对象，40~50岁10名男性健康受试者为成人对照组，10名同年龄段接受健康查体老年人为老年对照组，记录一般资料，应用CT技术扫描腹部和大腿，通过专用软件计算相应肌肉面积。结果 研究组握力（36.44±14.15）kg明显少于成人对照组（77.30±22.69）kg （P=0.001），研究组小腿围（25.18±2.31）cm 明显少于成人对照组（27.62±2.33）cm （P=0.006）。CT扫描显示研究组与成人对照组L3（第3腰椎）平面腹部面积、皮下脂肪面积、腹腔脂肪面积和竖脊肌总面积相近，研究组腹部肌肉面积（12 094.23±1 970.30）mm^2和竖脊肌肌肉面积（1 642.60±266.90）mm^2明显少于成人对照组的（17 462.00±1 600.58）mm^2和（2 003.50±350.91）mm^2（P=0.001, P=0.007）。L3骨骼肌指数为50.64±7.52，存在肌肉减少症（≤52.4）为66.7 %（20/30）。与同年龄正常查体老人腹部肌肉CT结果相似。研究组下肢骨骼肌面积明显少于成人对照组（P=0.001），下肢脂肪和股骨面积两组比较差异无统计学意义（P＞0.05）。结论 老年腹股沟疝患者肌肉质量和力量明显低于成人对照组，CT技术可作为评价工具。
Objective To evaluate the muscle mass in elderly patients with inguinal hernia using CT scan. Methods 30 male （age 70-90 years） hospitalized patients scheduled to receive surgery for inguinal hernia were selected into study group, 10 male health volunteers （40-50 years） were involved in adult control group, and 10 men of the same age as the study receiving annual physical examination were enrolled as elderly control group. General information were recorded; CT scanning of the stomach muscles and thigh muscles were conducted, and the muscle area was calculated using a special software. Results The index of grip strength in the study group was significantly lower than the adult control group [（36.44±14.15）kg vs. （77.30±22.69）kg, P=0.001], the calf circumference in the study group was significantly less than the adult control group [（25.18±2.31）cm vs. （27.62±2.33）cm, P=0.006]. There was no significant difference in L3 abdominal area, subcutaneous fat area, abdominal fat area, and vertical spinal muscular volume between the study group and the adult control group; while the L3 abdominal muscle area and vertical spinal muscular mass was significantly less in the study group than in the adult control group [（12 094.23±1 970.30）mm^2 vs. （17 462.00±1 600.58）mm^2, P=0.001; （1 642.60±266.90）mm^2 vs. （2 003.50±350.91）mm^2, P=0.007]. L3 skeletal muscle index of the study group was 50.64±7.52 and 66.7%（20/30） of the study group had sarcopenia （≤52.4%）. The CT findings of abdominal muscle of the study group were not significantly different from those of the elderly control group. The thigh muscle mass in the study group was significantly less than that in the control group （P=0.001）, but there was no significant inter-group difference in thigh fat and femur areas （P〉0.05）. Conclusion The muscle mass and strength in elderly patients with inguinal hernia are significantly lower than those of adult controls, for which CT scan can be applied for assessment.
