Abstract:
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.
