Recently, a Roux-en-Y stasis syndrome was described in a few patients after gastric operations. Although the clinical long term results are usually good, the motility of Roux-en-Y biliary limb has not been evaluated yet. In the present study, we report electromyographic studies of the gastrointestinal tract of two patients with chronic Roux-en-Y hepaticojejunostomy. These two patients provided a unique opportunity to evaluate the electromyographic activity of chronic Roux-en-Y limb in humans after one to five years. Seven pairs of bipolar extracellular electrodes were implanted in the antrum, duodenum, proximal part of the jejunum (15 centimeters proximal to the jejunojejunostomy), distal part of the jejunum (15 centimeters distal to the jejunojejunostomy), ileum, proximal Roux-en-Y limb and distal Roux-en-Y limb. All four phases of the migrating motor complex (MMC) were identified in the antrum and small intestine, including the Roux-en-Y limb, almost simultaneously to phase III in the duodenum. In the other two recordings (25 per cent), there was no relationship between phase III in the Roux-en-Y limb and that in the duodenum. Ingestion of food caused substitution of the MMC by the fed activity pattern in all recordings in the antrum and small intestine, including the Roux-en-Y limb. The findings of the present study indicate that the electromyographic activity of the Roux-en-Y limb may remain normal during fasting and fed states even many years after its creation.
最近，有少数患者在接受胃部手术后出现了一种Roux-en-Y淤滞综合征。尽管临床长期结果通常良好，但Roux-en-Y胆支的蠕动情况尚未得到评估。在本研究中，我们报告了对两名慢性Roux-en-Y肝空肠吻合术患者胃肠道的肌电图研究。这两名患者为评估Roux-en-Y肢体在术后一至五年的慢性肌电活动提供了独特的机会。七对双极细胞外电极分别植入胃窦、十二指肠、空肠近端（空肠吻合口近端15厘米处）、空肠远端（空肠吻合口远端15厘米处）、回肠、Roux-en-Y肢体近端和Roux-en-Y肢体远端。在胃窦和小肠，包括Roux-en-Y肢体，均可识别出移行性运动复合波（MMC）的所有四个阶段，几乎与十二指肠的III期同时出现。在另外两次记录中（25%），Roux-en-Y肢体的III期与十二指肠的III期之间没有关联。进食导致胃窦和小肠（包括Roux-en-Y肢体）的所有记录中，MMC被进食活动模式所取代。本研究结果表明，即使在Roux-en-Y肢体创建多年后，其在禁食和进食状态下的肌电活动可能仍保持正常。
