摘　　要：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 evaluate the function of MTB in gastric emptying of FD.Method The stomach was de-vided into the proximal and distal parts through the midgastric transverse band (MTB).The gastric emptying and intragastric distribution were investigated in 36 patients by SPECT tehnique.Results 52.8% patients had delayed gastric emptying in the proximal, distal stomach and region of the MTB. The width and area of MTB could decrease with improvement of the gastric emptying in FD patients. Cisapride can shorten the emptying time of some patients, especially in the proximal stomach . Conclusions Distrudance of gastric emptying may relate to that of the proximal and distal stomach in FD patients. MTB may play an important role in transfer,distribution and emptying of food in the stomach. Regulating machanism of the MTB may be as a sluice gate.
