24小时食管pH及压力测定对胆总管囊肿术后胃食管反流的监测

目的 24h食管pH及压力测定及胆总管囊肿术后胃食管反流的监测。方法 对10年期63例先天性胆总管囊肿患儿中18例术后进行了24h食管双极pH及压力测定。结果 8例患儿出现胃食管反流，行囊肿切除肝管空肠Roux-Y吻合加抗反流装置3例，囊肿空肠Roux-Y吻合，无人工套叠4例，有人工套叠1例。结论 先天性胆总管囊肿术后可出现胃食管反流，反流与食管廓清运动能力无关，可能与异常的十二指肠活动有关。

Ambulatory 24-hour manometric and pH metric evidence of gastroesophageal reflux after operation of congenital choledochal cysts

Objective To monitor the ambulatory 24-hour manometric and Ph metric evidence of gastroesophageal reflux after operation of congenital choledochal cysts. Methods 18 case selected from 63 survivors of congenital choledochal cysts in past 10 years were reviewed for gastroesophageal reflux (GER) assessed by the combined ambulatory 24-hour manometric and Ph-metery.Results 8 of the patients were found to have GER. Among them, 3 patients had resection of the cyst with Roux-Y hepatojejunostomy with anti-reflux, 4 had cystojejunostomy without anti-reflux, and 1 had anti-reflux.Conclusions Patients with congenital choledochalcysts could develop gastroesophageal reflux. GER was more frequent in patients without anti-reflux operation. GER was not related with esophageal peristaltic activity and acid clearing capacity but related with abnormal duodenal motility.
