To explore the application of ultrasonography in the diagnosis of asymptomatic occult inguinal herniain patients with morbid obesity.

66 patients with asymptomatic occult inguinal hernia and morbid obesityin Wuhu Hospital of Traditional Chinese Medicine from November 2017 to November 2019 were enrolled in the study. All patients were diagnosed with asymptomatic inguinal hernia unintentionally by high-frequency ultrasound examination. The ultrasonic image characteristics were recorded, and the surgical results were taken as the gold standard. The sensitivity, specificity and accuracy of ultrasound in the diagnosis of asymptomatic occult inguinal hernia in obese patients were analyzed.

58 of the 66 patients with morbid obesity and asymptomatic occult inguinal hernia diagnosed by ultrasound were treated with surgery, and 54 were diagnosed as inguinalhernia, 3 cases were femoral hernia, 1 case was lymphadenopathy. The symptoms of the remaining 8 cases improved after conservative treatment, and there was no progress in regular follow-up. With surgery as the gold standard, the sensitivity, specificity and accuracy of ultrasound in the diagnosis of asymptomatic occult inguinal hernia in obese patients were 91.38% (53/58), 16.67% (1/6) and 87.10% (54/62), respectively.

Ultrasound diagnosis of asymptomatic inguinal hernia combined with morbid obesity is highly effective, but there are still false negatives. Morbid obesity may become a factor affecting the ultrasound diagnosis of inguinal hernia. Clinically, obese patients with suspected inguinal hernia should pay attention to physical examination and clinical identification, and perform surgical exploration if necessary.
