Pylorus Dysfunction After Esophagectomy and Gastric Tube Reconstruction. Effect of Pneumatic Pylorus Dilatation During Hospital Stay, Surgical Complications During in Hospital Stay

Not Applicable

• Conditions: Esophagectomy; Delayed Gastric Emptying; No Signs of Cancer Recurrence

• Registration Number: NCT02086461
• Lead Sponsor: Karolinska University Hospital

Brief Summary

Delayed emptying of the gastric tube after esophagectomy is a frequent and durable problem. No treatment is currently available. It can be hypothesized that incomplete relaxation of the pyloric sphincter may be a significant contributing factor. Pneumatic dilatation may therefore be a potentially effective treatment.

Detailed Description

Patients surviving one year after esophagectomy are sent questionnaires to pick up symptoms suggestive of delayed gastric emptying.Those fulfilling predefined criteria for delayed gastric emptying will be invited to the study. The study design is sham controlled single blind with a follow up extending to twelve months post treatment.
