目的 探讨功能性消化不良(FD)胃排空与胃中间横带(MTB)关系。方法 以MTB为界,将胃分为近端胃与远端胃,应用SPECT技术检测了36例患者的全胃及分区胃排空、食物在胃内分布情况。结果52.8％FD患者存在胃排空障碍,其近端、远端及MTB区均慢于对照组;MTB的宽度与面积随着胃排空的改善而减少;西沙比利能缩短部分FD患者胃排空时间,尤以近端明显。结论 FD患者胃排空延迟可能与近端、远端均有关,MTB在调节食物胃内转运、分布及排空中发挥重要作用,其调节机制可能是“闸门”作用。
Objective To investigate the relationship between gastric emptying and medial transverse band (MTB) in functional dyspepsia (FD). Methods MTB was used to divide the stomach into proximal stomach and distal stomach. SPECT technique was used to detect the gastric and regional gastric emptying in 36 patients and the distribution of food in the stomach. Results 52.8% FD patients had gastric emptying disorder, and their proximal, distal and MTB areas were slower than those in the control group. The width and area of MTB decreased with the improvement of gastric emptying. Cisapride could shorten the gastric mass in some FD patients Emptying time, especially in the proximal obvious. Conclusions Delayed gastric emptying in FD patients may be related to the proximal and distal ends. MTB plays an important role in regulating intragastric transit, distribution and emptying of food, and its regulatory mechanism may be a “gate” effect.
