Summary

Enterogastric reflux is common in patients after colonic interposition surgery for esophageal issues. This duodenal reflux may contribute to colitis in the transplanted colonic graft.

Area of Science:

  • Gastroenterology
  • Surgical Innovation
  • Esophageal Disease Management

Background:

  • Colonic interposition is a surgical technique for benign esophageal diseases.
  • The long-term effects of colonic grafts, particularly regarding reflux, require investigation.

Purpose of the Study:

  • To assess the incidence and characteristics of enterogastric reflux in patients with colonic interposition.
  • To evaluate the relationship between reflux and the health of the colonic graft mucosa.

Main Methods:

  • Scintigraphy was used to study enterogastric reflux in 20 patients.
  • Endoscopy evaluated the condition of the transplanted colonic mucosa.
  • 24-hour pH monitoring was performed in select patients.

Main Results:

  • Enterogastric reflux was observed in 16 patients; reflux into the colonic graft occurred in 8.
  • No difference in reflux rates was found between isoperistaltic and antiperistaltic interpositions.
  • Colitis in the graft was associated with duodenal reflux in all three affected patients.

Conclusions:

  • Enterogastric reflux is a frequent complication following colonic interposition.
  • Duodenal reflux into the colonic graft may play a role in the development of graft colitis.
