Roux-en-Y limb motility after total gastrectomy

Area of Science:

• Gastroenterology
• Surgical Oncology
• Digestive Motility Disorders

Background:

• Roux-en-Y stasis syndrome is a known complication following gastrectomy.
• Gastric resections for cancer and bariatric surgeries are increasing, making Roux-en-Y limb (RYL) motility crucial.
• Understanding RYL motility post-total gastrectomy is essential for managing post-surgical complications.

Purpose of the Study:

• To evaluate the motility of the Roux-en-Y limb (RYL) after total gastrectomy using high-resolution manometry (HRM).
• To correlate RYL motor activity with clinical symptoms in patients who underwent total gastrectomy.

Main Methods:

• High-resolution manometry (HRM) was performed on 8 asymptomatic patients.
• Patients had undergone total gastrectomy for proximal gastric cancer with Roux-en-Y reconstruction.
• Motility was assessed in the RYL at varying distances below the esophagojejunal junction.

Main Results:

• Esophageal motility was found to be normal in all patients post-total gastrectomy.
• Motor activity was consistently detected in the proximal RYL, but peristalsis was abnormal in 63% of patients.
• Simultaneous waves were observed in 75% of patients, and no patient showed complete absence of motor activity.

Conclusions:

• Total gastrectomy with Roux-en-Y reconstruction preserves normal esophageal motility.
• While motor activity is present in the proximal RYL, peristalsis is frequently abnormal.
• The absence of normal peristalsis in the RYL does not necessarily lead to symptomatic Roux-en-Y stasis syndrome.
