Type 4 giant hiatal hernias are not common. The stomach is herniated, as well as viscera in the mediastinum, colon, spleen, and even sometimes in the pancreas. Repair is challenging for different reasons. This type of hernia is frequent in older and fragile patients. Reduction of the sac from the mediastinum is mandatory and must be carried out following stepwise and precise dissection rules: it has to be done outside of the sac, in an anatomical cleavage plane. Crural repair is challenging and must be tailored on the quality of the diaphragmatic musculature and size of the orifice. Anti-reflux repair must be performed as well. The laparoscopic approach has radically improved the clinical outcome of this procedure in old patients.
