Short-segment colon interposition for end-stage achalasia

Abstract

Background The reoperative procedures for achalasia vary. Repeat esophagomyotomy with or without antireflux procedure and esophageal resection of varying extent with reconstruction using stomach, jejunum, or colon have been reported. In this series, we have retrospectively reviewed our experience and reported the results with limited distal esophagectomy and short-colon interposition in the treatment of patients with recurrent symptoms of achalasia after prior failed esophagomyotomy. Methods Nine consecutive patients (5 men, 4 women; 27 to 74 years of age; mean, 52 years) with recurrent symptoms of achalasia and at least one failed prior esophagomyotomy underwent gastric cardiectomy, distal esophagectomy, and replacement with an at least 30-cm short-colon interposition through a left thoracoabdominal approach. Morbidity of the procedure and the length of hospital stay were recorded. The symptomatic evaluation, ability to have a meal, and overall patient satisfaction after the operations were assessed. Results Follow-up results were available in 8 patients. One patient had intestinal strangulation with graft failure 3 days after operation. Takedown of the graft and end-to-side esophagogastrostomy were successful. There was no mortality. Outcome assessment was completed at a median of 6 years (range, 1 to 12 years). Overall patient satisfaction was good in 6 patients, and fair and worse in 1 patient each. Most of the patients could have regular meals. Two patients had intermittent abdominal fullness after meals. Six of these 8 patients would have the operation again. Conclusions Limited distal esophagectomy with short-colon interposition through a left thoracoabdominal approach is a safe and feasible alternative to near total esophagectomy in patients with achalasia who have prior failed esophagomyotomy. Improved alimentary function was observed in most of the patients after operation, which resulted in a better quality of life.
