| 目的 观察胃肠超声助显剂用于评估肠系膜上动脉综合征(SMAS)患者胃排空状态的可行性。方法 前瞻性对30例SMAS患者(SMAS组)及24名健康志愿者(对照组)行胃肠超声检查,测算胃肠助显剂通过即刻十二指肠近端内径(D)、肠系膜上动脉与腹主动脉夹角处十二指肠内径(d)及十二指肠受压程度(D－d)/D,记录服用助显剂后5 min (T0)、30 min (T1)、60 min (T2)、90 min (T3)及120 min (T4)胃残余容量(GRV),分别计算T1~T4 GRV与T0 GRV比值(GRV1~GRV4)并进行组间比较;以Pearson相关分析观察SMAS患者(D－d)/D与GRV1~GRV4的相关性。结果 SMAS组D、(D－d)/D、GRV1、GRV2、GRV3及GRV4均大于,而d小于对照组(P均＜0.05)。SMAS患者(D－d)/D与GRV4呈中度正相关(r=0.509,P=0.007),而与GRV1~GRV3无明显相关性(P均＞0.05)。结论 胃肠超声助显剂可用于实时动态观察SMAS患者胃排空状态及定量分析GRV。 |

| Objective To observe the value of gastrointestinal ultrasound contrast agents for evaluating gastric emptying status in patients with superior mesenteric artery syndrome (SMAS). Methods Gastrointestinal ultrasound was prospectively performed in 30 SMAS patients (SMAS group) and 24 healthy subjects (control group). The diameter of proximal duodenum (D), the maximum diameter of duodenum at the angle between superior mesenteric artery and abdominal aorta (d), as well as the degree of duodenum compression (D-d/D) were measured after gastrointestinal contrast agents passing through immediately. Gastric residual volume (GRV) at 5 min (T0), 30 min (T1), 60 min (T2), 90 min (T3) and 120 min (T4) after taking contrast agent were recorded, and the ratio of T1—T4 GRV to T0 GRV (GRV1—GRV4) were calculated and compared between groups. Pearson correlation analysis was performed to explore the correlation of (D-d)/D with GRV1—GRV4 in SMAS patients. Results D, (D-d)/D, GRV1, GRV2, GRV3 and GRV4 in SMAS group were all higher, while d in SMAS group was lower than those in control group (all P＜0.05). (D-d)/D in SMAS patients was moderately and positively correlated with GRV4 (r=0.509, P=0.007), but not significantly correlated with GRV1—GRV3 (all P＞0.05). Conclusion Gastrointestinal ultrasound contrast agents could be used to real-time dynamically observe gastric emptying status in patients with SMAS and quantitatively analyze GRV. |
