[Pharyngo-colonic anastomosis for esophageal reconstruction in the treatment of diffuse corrosive esophageal stricture]

To observe the experience and the outcome of pharyngo-colonic anastomosis for esophageal reconstruction in diffuse corrosive esophageal stricture involving hypopharynx.This retrospective report reviews the experience and results of 14 patients who underwent esophageal reconstruction by pharyngo-colonic anastomosis without resection of intra thoracic stricture esophagus. The left half colonic segment was pulled up to the neck through the substernal space in all patients.There was no operative or hospital death. Postoperative complications include cervical anastomotic fistula in four patients, rupture of the abdominal incision in 1. The length of follow-up ranged from half year to 10 years with an average of 4 years. Anastomotic stenosis occurred in 2 patients. One case improved after dilatation and the other one healed by plastic operation. One patient began to vomit after diet in seven months later with barium swallowing the abdominal colon graft was redundant and this patient was cured with side by side between the colon and the stomach.The successful reconstruction for hypo-pharyngo-esophageal stricture requires a correct and larger hypopharyngeal opening and a good anastomotic technique. From our experience this procedure is shown to be safe and effective.
