The authors submit an uncommon case of a true leftsided posterolateral (Bochdalek) hernia with the stomach, transverse colon and spleen in the hernial sac in a 25-year-old patient. They assume that the large hernation developed as a result of rupture of an already congenitally preformed hernial opening as a result of intraabdominally increased pressure during repeated pregnancies. The authors describe effective surgical solution of the case by laparoscopy from a transabdominal approach.
