Based on the clinical presentation of an empty right scrotal sac and a palpable mass in the right inguinal canal, it is very likely that the patient has an inguinal hernia, which is a condition where a part of an abdominal organ, such as the intestines or omentum, protrudes through a weakness in the muscles of the abdominal wall near the groin.
While the majority of umbilical hernias are present at birth or develop in early childhood, inguinal hernias are more common in boys between the ages of 5 and 12. They are caused by a weakness in the abdominal wall muscles in the inguinal canal, which allows for these organs to protrude in the groin area.
The mass that has been palpable in the right inguinal canal is likely to be a portion of an organ, such as a section of the intestines, that has herniated through the inguinal canal and into the scrotum. The inguinal canal is a narrow passageway that connects the groin to the abdomen, and it allows for the passage of the spermatic cords, blood vessels, and the intestines.
It is important to remove the inguinal hernia as soon as possible to prevent complications such as intestinal strangulation, which can lead to severe abdominal pain, nausea, vomiting, and diarrhea. Additionally, a strangulated hernia can result in intestinal perforation and peritonitis, which are life-threatening complications.
