Gastric outlet obstruction with perforation. A rare presentation of left-sided adult Morgagni hernia

Adult presentation of congenital diaphragmatic hernia (CDH) is rare. Out of the three varieties of CDH, Morgagni hernia is the rarest of all. Though most of them are asymptomatic and may be incidentally detected, they may also present in the emergency setting with respiratory or gastrointestinal features like obstruction or strangulation. Gastric outlet obstruction is a rare manifestation of adult Morgagni hernia. We present a case of adult left-sided Morgagni hernia with features of gastric outlet obstruction complicated with perforation.
