Paraesophageal hiatus hernia can be a morbid and even lethal condition
. Although many complications from this entity have been described, th
ey almost always involve gastric incarceration and its related complic
ations. Occasionally, the transverse colon or spleen may be involved i
n the hernia, causing additional symptoms. An unusual case of paraesop
hageal hiatus hernia involving incarceration of the pylorus, proximal
duodenum, and pancreatic head is described. The patient's presentation
, operative management, and perioperative course are discussed to emph
asize the importance of early repair of paraesophageal hiatus hernia b
efore the development of such occurrences.
