The Roux-en-Y stasis syndrome is a troublesome postgastrectomy syndrome. Although the era of gastric resection for peptic ulcer disease has almost come to an end, the increasing incidence of proximal gastric cancer and the outbreak of bariatric operations make the study of the motility of the Roux-en-Y limb (RYL) after gastric resection or gastroplasty very relevant.This study aims to evaluate the motility of the RYL after total gastrectomy using high-resolution manometry (HRM). We performed an HRM on 8 patients after total gastrectomy for proximal gastric cancer and Roux-en-Y reconstruction, 74 ± 111 months after the operation. At the time of the study, all patients were asymptomatic without evidence of cancer recurrence.Peristaltic waves were noticed at the RYL in 3 (37%) of the patients. The mean wave amplitude of the peristaltic waves was 63 ± 29 (37-94) mmHg and 83 ± 35 (42-104) mmHg at 3 and 7 cm below the esophagojejunal junction, respectively. Simultaneous waves were noticed in 6 (75%) of the patients in 80 ± 32 % (30-100) of the swallows of these patients. No patient presented with absence of motor activity detectable at the HRM. Our results show that: (1) esophageal motility is normal after total gastrectomy with Roux-en-Y reconstruction; (2) motor activity is always detectable at the proximal RYL, but peristalsis is abnormal in most patients; and (3) absence of peristalsis does not translate into symptoms.
Roux-en-Y 淤滞综合征是一种棘手的胃切除术后综合征。尽管胃切除术治疗消化性溃疡病的时代几乎已经结束,但近端胃癌发病率的上升和减重手术的爆发使得胃切除或胃成形术后 Roux-en-Y 袢(RYL)的动力研究变得非常相关。本研究旨在使用高分辨率测压法(HRM)评估全胃切除术后 RYL 的动力。我们对 8 例因近端胃癌而行全胃切除术和 Roux-en-Y 重建的患者进行了 HRM 检查,手术时间为 74 ± 111 个月。在研究时,所有患者均无症状,无癌症复发的证据。在 3 名(37%)患者的 RYL 中观察到蠕动波。蠕动波的平均波幅分别为食管胃交界处下方 3 和 7 cm 处的 63 ± 29(37-94)mmHg 和 83 ± 35(42-104)mmHg。6 名(75%)患者在 80 ± 32%(30-100)次吞咽中同时出现波。没有患者在 HRM 可检测到无运动活性。我们的结果表明:(1)全胃切除和 Roux-en-Y 重建后食管动力正常;(2)近端 RYL 始终可检测到运动活性,但大多数患者的蠕动异常;(3)无蠕动并不意味着会出现症状。
