目的采用超声全胃圆柱体法(UWSCM)评价系统性红斑狼疮(SLE)胃受累患者胃排空。方法应用UWSCM对80例健康志愿者及15例SLE胃受累患者胃排空25%(T1)、胃排空50%(T2)及胃排空75%(T3)的时间进行测定对比,并与SLE患者的临床症状评分结果进行相关性分析。结果 SLE胃受累患者胃排空时间T1比正常组缩短(17.13±3.68vs 19.96±4.92,P<0.05)。T3比正常组显著延长(83.73±7.35vs 74.26±8.60,P<0.05),且与症状指数相关性最好(r=0.706,P<0.01)。结论 SLE胃受累患者的胃排空时间异常,并与其部分上消化道症状相关。UWSCM可以为SLE胃受累患者的胃排空异常提供准确的依据。
Objective To evaluate gastric emptying in patients with gastric involvement in patients with systemic lupus erythematosus (SLE) by ultrasound total stomach cylinder method (UWSCM). Methods The time of gastric emptying 25% (T1), gastric emptying 50% (T2) and gastric emptying 75% (T3) in 80 healthy volunteers and 15 patients with SLE gastric involvement were measured and compared by UWSCM. SLE patients clinical symptom score results were analyzed. Results The time of gastric emptying T1 in patients with gastric involvement in SLE was shorter than that in normal subjects (17.13 ± 3.68 vs 19.96 ± 4.92, P <0.05). T3 was significantly longer than the normal group (83.73 ± 7.35 vs 74.26 ± 8.60, P <0.05), and had the best correlation with the symptom index (r = 0.706, P <0.01). Conclusions Gastric emptying time is abnormal in patients with SLE gastric involvement and is associated with some upper gastrointestinal symptoms. UWSCM can provide an accurate basis for abnormal gastric emptying in patients with SLE gastric involvement.
