Impending rupture of the stomach associated with malrotation and midgut volvulus.

Two cases of impending gastric rupture, associated with malrotation and midgut volvulus, are reported. The diverticulous mucosal protrusions were characteristically revealed as a box-shaped gastric shadow in the plain X-ray and upper GI series. Two cases were operatively treated with only the seromuscular suture of the defect without excision of the mucosal protrusion. Midgut volvulus and malrotation were reduced. Post-operative course was uneventful.
