Necropsy photograph of a 4-year-old, male castrated guinea pig diagnosed with gastric dilation without volvulus and a jejuno-jenjunal intussusception. The stomach is severely distended causing caudal displacement of the intestines. The duodenum and jejunum (right abdomen) are dilated, hyperemic, and dark red to black in appearance consistent with necrosis.

Necropsy photograph of a 4-year-old, male castrated guinea pig diagnosed with an 8.5 cm jejuno-jenjunal intussusception. The intestines cranial to the intussusception (asterisk) are congested and hyperemic, with dilation and necrosis secondary to an outflow obstruction. The intestines caudal to the intussusception are normal in width and texture.
