[Surgical treatment of sliding hiatal hernia using a modified Collis' technic]

The technique suggested in 1954 by Collis for the surgical treatment of sliding hiatal hernia is based upon relevant anatomical and physiological analysis. Its originality lies essentially in the pre-esophageal closure of the upper part of the hiatus. With a few changes, in particular a midline super-umbilical approach, the Collis operation is a technically very easy and hence rapid procedure, which can widen the range of surgical indications to include patients generally not considered to be appropriate.
