Long-term follow-up of endoscopic stapled diverticulotomy.

We report a consecutive series of 31 patients who underwent endoscopic stapled diverticulotomy. The patients' notes were reviewed retrospectively to gather data on their original admission and a postal survey was conducted to establish patient satisfaction, their ability to swallow and re-operation data. Three patients were lost to follow-up. Nine of the remaining 28 died at a median of 18 months. The remaining 21 were followed up for a median of 59 months. The data showed that, at 5 years, 94.4% of patients had an improvement in their swallowing, and 50% had an entirely normal swallow. In order to achieve this result, 19% of patients required a second procedure, and one patient (3.2%) required a third (open) procedure. Endoscopic stapled diverticulotomy has well-established, short-term advantages. This series shows that it has a good long-term outcome that is similar to established open techniques and probably better than other techniques of endoscopic diverticulotomy, i.e. diathermy or laser.
