Don't be too alarmed if we find a small bag suddenly appearing in a certain part of the dog. Some owners often associate small bags with tumors, but it is not necessarily tumors that can cause these small bags. Hernia is one of the common causes. Hernia can be divided into reversible hernia and irreversible hernia. According to different positions, it can be divided into umbilical hernia, inguinal hernia and abdominal hernia. As for how to deal with it, it needs to be judged according to its severity. If the hernia is mild and does not get bigger, it generally does not need to be treated.
1. Umbilical hernia: Abdominal organs are stripped to the subcutaneous through umbilical foramen. Umbilical hernia is a common disease in dogs. The contents of hernia may be tarsal ligament, omentum or small intestine. The reasons are mostly congenital umbilical developmental defects and incomplete umbilical foramen closure, and may also be caused by excessive umbilical foramen tension, short umbilical cord or umbilical cord infection after birth.
Symptoms: the navel has round protrusions of different sizes and feels soft. Painless, without heating, the hernia hole can be felt when pressed, and the hernia contents can be recovered when pressing the hernia sac or the supine position of the animal, and the swelling increases when struggling or eating. This is a reversible umbilical hernia. In a few cases, the hernia contents are adhered or occluded, and the wall of the cyst is tense by palpation. Pressing or changing the position can not make the hernia contents return. If the content of incarcerated hernia is intestine, it will show the symptoms of acute abdomen. Abdominal pain, anorexia, vomiting, fever and severe shock may occur.
Treatment: If the size of umbilical hernia increases with time, it should be solved by surgery.
2. Inguinal hernia: The internal organs of the abdominal cavity protrude through the inguinal ring, which is called inguinal hernia. The contents of hernia can be part of omentum, bladder, small intestine, large intestine and spleen, uterus or broad ligament, round ligament, etc. Bitches are frequent Male dogs are also called inguinal scrotal hernia. Most of the causes are congenital inguinal ring atresia or acquired abdominal pressure, which can also be seen in trauma factors.
Symptoms: unilateral or bilateral inguinal protuberance swelling, tumor size is uncertain. Reversible hernia feels soft, painless and without heat. Irreducible hernia palpation is accompanied by heat pain, hernia sac tension, intestinal prolapse and incarceration, which shows the symptoms of acute abdomen. Male dogs, the contents of hernia are mainly in scrotum, which is easy to block, so it shows unilateral or bilateral scrotum enlargement.
Treatment: Baoding, disinfection, midline incision of abdomen and back, incision across hernia sac, opening hernia sac and accepting hernia contents. When the contents are too large, the groin ring can be enlarged and accepted. Tighten the peritoneum of hernia sac, remove the redundant part of hernia, sew the inner and outer groin rings with layered nodules, protect the pudendal vessels and nerves, and close the skin incision. In male dogs, the scrotum is cut to return the hernia contents and the inguinal ring is closed.
If it doesn't get worse, some minor hernias can be left untreated.
3. Abdominal hernia: Abdominal internal organs are separated from the skin through traumatic abdominal wall rupture holes, which is called traumatic abdominal hernia. It often happens in car accidents, falls and other external forces or mutual biting between animals, which leads to the rupture of abdominal wall muscle layer or peritoneum and the surface skin remains intact, or the suture in abdominal wall incision breaks and the incision splits after abdominal surgery. The rupture of muscularis ventralis may be the rupture of external oblique muscle, internal oblique muscle and transverse abdominis muscle, while the rupture of muscularis ventralis is mainly the rupture of rectus abdominis or anterior pubic tendon.
Symptoms: Abdominal skin is cystic, and there may be scratches, contusions and other damage marks on the skin. Hernia sac varies in size, and its volume changes with the filling and emptying of hernia contents. Touch its soft or hard texture, neither hot nor painful, nor warm nor painful. The hernia ring can be felt in the early stage, and the contents of the hernia are acceptable. For a long time, due to local inflammation, the outline of hernia is unclear and the contents of hernia cannot be recovered. If incarceration occurs, it will cause symptoms of acute abdominal hernia.
Treatment: first of all, we must stabilize the dog's condition. The operation site is at the hernia sac, and the reduction principle is the same as that of umbilical hernia operation.
