We aimed to determine the difference in tissue stiffness, which might reflect histologic damage, by comparing the potential of the shear wave elastography (SWE) values of operated undescended testes (OUT) with those of undescended testes (UT) and normal testes. A total of 120 patients (235 testes) were enrolled in the current study. Quantitative SWE values were measured by manually drawing contours of the entire testis structure with a free region of interest. A group of 66 OUT were classified as group A. Operation age and the period passed over the operation time and SWE values were compared among the testes assigned to group A. The 50 testes having inguinal canal placement were classified as group B, and the 119 testes whose sonography findings were normal were classified as group C. These 3 groups were compared in terms of the SWE values and volume. The SWE values of group A were significantly higher than those of groups B and C (P < 0.001). The SWE values of group B were significantly higher than those of group C (P < 0.001). The SWE values of OUT were significantly higher than those of the contralateral normal testes and UT (P < 0.001). There were no significant differences among operation age and period passed over the operation time and SWE values in the OUT (P > 0.05). There was no significant correlation between SWE values and testes' volume (P > 0.05). The SWE technique can be used effectively as a new parameter to assess stiffness of the OUT and UT to predict interstitial fibrosis and the severity of histologic damage.

This report is related to the unusual case of an 11-year-old boy presenting with acute gastric dilatation after the intake of excessive food and carbonated beverages after a 12-hour fasting who died of complications of acute reperfusion syndrome after decompression of the stomach with gastrotomy. An enormously distended stomach was encountered without volvulus and obstruction in the operation. Autopsy and histological findings revealed a severely distended stomach, the walls of which were notably thin and displayed transmural necrosis. The reported case demonstrated that enormous food and beverage intake may cause acute gastric dilatation and gastric necrosis, and subsequently, sudden death may develop in children. The subject reported here is the youngest child in literature dying from acute gastric dilatation and necrosis without any underlying disorders and exposed to autopsy.
