目的探讨管状胃代食管术后胃食管反流程度。方法按手术方式将31例食管癌患者分为管状胃(A)组和传统手术(B)组。术后1周,胃肠功能动态pH值监测仪测定24 h的pH值。记录全天的反流次数、长反流(>5 min)次数、最长反流持续时间、pH<4的时间及其占全天的比率。结果与B组比较,A组反流次数少[(10.85±16.85)次vs.(0.22±0.44)次],长反流次数少[(2.00±0.00)次vs.(0.42±0.78)次],最长反流持续时间短[(4.28±6.04)min vs.(0.22±0.66)min],时间pH<4(pH<4的时间)短[(15.00±18.60)min vs.(0.55±0.88)min],时间pH<4分数(pH<4的时间占全天的比率)小[(1.18±1.44)%vs.(0.05±0.13)%],DeMeester评分低(4.90±6.07)分vs.(0.42±0.29)分。结论管状胃食管吻合能有效降低食管癌患者术后胃食管反流的发生
Objective To investigate the degree of gastroesophageal reflux after tubular gastric esophageal surgery. Methods Thirty-one patients with esophageal cancer were divided into two groups according to the operation method: tubular stomach (A) group and traditional surgery group (B). One week after operation, the pH value of gastrointestinal function dynamic pH monitor was measured at 24 h. Record the number of reflux days, long reflux (> 5 min), duration of the longest reflux, pH <4, and their ratio over the day. Results Compared with group B, the number of reflux in group A was less ([(10.85 ± 16.85) vs. (0.22 ± 0.44)], and the number of long reflux was less [(2.00 ± 0.00) vs. (0.42 ± 0.78) (4.28 ± 6.04) min vs. (0.22 ± 0.66) min], the time of pH <4 (time of pH <4) was short [(15.00 ± 18.60) min vs. (0.55 ± 0.88 ) min], the time of pH less than 4 (the ratio of time of pH <4 to the whole day) was small (1.18 ± 1.44)% vs (0.05 ± 0.13)%, DeMeester score was lower (4.90 ± 6.07) (0.42 ± 0.29) points. Conclusion Tubular gastroesophageal anastomosis can effectively reduce the occurrence of gastroesophageal reflux after esophageal cancer
