Roux-en-Y Limb Motility after Total Gastrectomy

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.
