Is a patent processus vaginalis a hernia?
Indirect inguinal hernia is the protrusion of an abdominal organ into a patent processus vaginalis extending into the inguinal canal. A hernia in a child is seldom symptomatic unless it is incarcerated. Physical examination may reveal a reducible, firm bulge in the groin and scrotum.
How patent processus vaginalis causes hernia?
Inguinal Hernias and Hydroceles A significant factor in the development of an inguinal hernia is excess fluid in the peritoneal cavity, and in patients with a patent processus vaginalis, procedures that introduce fluid into the peritoneal cavity may induce a hernia or hydrocele.
What is a persistent processus vaginalis?
The occurrence of inguinal hernias is due to the persistence of the processus vaginalis (6,7). The processus vaginalis is a blind-ending sac extending from the peritoneum to the scrotum, which is layered by celomic epithelium (8). This generally obliterates upon the conclusion of testicular migration (6,7).
What is a patent processus?
A patent processus vaginalis (PPV) allows a communication between the peritoneum and scrotum. Hydrocoele is the usual presentation of a PPV in children. However, with intraabdominal pathology the patent PPV may provide the first clue to the mischief within the abdomen.
What happens to processus vaginalis in females?
In normal human prenatal development, the processus vaginalis closes at around week 40 of gestation, preventing its opening at the internal ring, but when this fails, pediatric indirect hernia can occur.
Where does the processus vaginalis come from?
The processus vaginalis (or vaginal process) is an embryonic developmental outpouching of the peritoneum. It is present from around the 12th week of gestation, and commences as a peritoneal outpouching. n males, it precedes the testis in their descent down within the gubernaculum, and closes.
Is processus vaginalis same as tunica vaginalis?
The outer layer of peritoneum, the processus vaginalis (tunica vaginalis reflexa), is reflected on to the testis to form the serous outer layer of that organ, the tunica vaginalis propria.
