Mercedes-Benz pyloroplasty: a new technique.

Closure of large duodeno-pyloro-gastrotomy can be difficult. The resulting 'pyloroplasty' may lead to major deformity at the gastric outlet. We describe a technique that combines features of the Heineke-Mikulicz pyloroplasty and V-Y plasty. The technique is simple and is not associated with any new post-operative problem.
