Abstract:
Objective To compare the esophageal acid and alkaline exposure characteristics of patients with cardia carcinoma after proximal gastrectomy or total gastrectomy.Method A total of 77 patients of cardia carcinoma who underwent radical resection from Sep 2007 to Sep 2011 in our hospital were retrospectively reviewed.24 hour esophageal pH monitoring were performed in all patients.Result Patients were divided into three groups:group TG had total gastrectomy (n =25),group PP had proximal gastrectomy with pyloroplasty (n =33),group NP had proximal gastrectomy (n =19).It revealed that indicators of acid reflux including the overall time length of acid episodes,＞ 5 min times of acid episodes,duration of longest acid episodes,time length of pH ＜ 4.00 and the DeMeester Scores in group NP were significantly higher than in group PP(U =32,P ＜ 0.01 ; U =35,P ＜ 0.01 ; U =23,P ＜ 0.01 ; U =39,P ＜0.01 ;U =49,P ＜0.01 respectively).Only alkline reflux was observed in group TG.The total times of alkaline episodes in PP group was significantly lower than in group TG(U =52,P ＜0.01) and group NP (U =182,P ＜0.01).＞5 min times of alkaline episodes in group TG was larger than in group PP,and that in group PP was larger than in group NP(P ＜0.01).Duration of longest alkaline episodes and total period of pH ＞7.00 in group PP was significantly higher than in group TG(U =125,P ＜ 0.01 ; U =143.5,P ＜ 0.01),and that in group TG was higher than in group NP(U =23.5,P ＜ 0.01 ; U =14,P ＜ 0.01).Conclusions Alkaline reflux deserves more attention in evaluating esophageal reflux in patients with cardia carcinoma after resection.Pyloroplasty is not helpful to relieving esophageal acid episodes while causing severe alkaline reflux.
