摘　　要：目的:研究食管癌术后早期胸胃排空的生理机制。方法:应用放射性核素对38例食管癌术后患者进行术前及术后24 h的流食胃排空检查,分析胃半排空时间(GET 1/2)的变化。结果:术后未出现胃潴留症状。30例(78.9%)患者术后胃排空显著快于术前(P<0.01)。术前男性胃排空时间显著快于女性(P<0.05),而在术后男女性之间则无显著性差异(P>0.05)。结论在重力作用的影响下,术后早期胸胃对流食的排空较术前显著加快,胸胃只是作为无功能的连接管道而存在。Objective： To study the physiological mechanisms of intrathoracic gastric emptying after esophagectomy. Methods： Between March 2008 and June 2009, the gastric emptying（ GE ） of liquid food was evaluated in 38 patients （ 27 males and 11 females ） preoperatively and at 24h after esophagectomy and cervical esophagogastrostomy for esophageal cancer. Studies were performed in seated body position by radioisotope. The gastric emptying time 1/2 （ GET 1/2 ） was recorded and analyzed. Results： There was no gastric retention in all subjects. After operation, GE was significantly faster in 30 patiens （ 78.9% ） （ P 〈 0.05 ）. Before esophagectomy, male patients had significantly faster GE than female patients （ P 〈 0.05 ）, but GE was not significantly different between male patients and female patients after esophagectomy （ P 〉 0.05 ）. Conclusion： Intrathoracic gastric emptying for liquid food afteresophagectomy is significantly faster than that before operation in the upright position because of the force of gravity. It seems that intrathoracic stomach acts as a nonfunctioning tract.
