[Subcardial ulcer and the Nissen technic. Apropos of a case of recovery by partial release of the fundoplication].

Gastric ulcer, an uncommon complication of Nissen technique, is nevertheless reported in all series (between 1 and 5% of cases). The authors report a case occurring after a complete fundoplication associated with a longitudinal stapling of the cardia (Rignault's procedure) which resolved after reoperation and transformation into a posterior hemi-valve. The pathogenesis of post-Nissen gastric ulcer is discussed; the mechanical factor appears to be decisive in the subcardial site. Surgical revision according to various modalities is generally unavoidable.
