Self-expanding metallic stents in the management of pyloric dysfunction after gastric pull-up operations

The purpose of this paper is to report the use and benefits of self-expanding metallic stents employed in pyloric dysfunction. Four patients treated with oesophagectomy and gastric pull-up for oesophageal carcinoma failed to respond to balloon dilatation for pyloric dysfunction. Three of the patients were thought to have residual tumour at sites remote from the pylorus prior to stenting, but the fourth, who had undergone surgery 8 years previously, was thought to be cured. All were treated with self-expanding metallic stents. All four patients responded well with resolution of their symptoms. Over a mean follow-up of 6 months there has been no recurrence of symptoms. Stent insertion represents a potentially valuable method of treatment in patients with post-surgical pyloric dysfunction in whom simple balloon dilatation has failed.
