Surgical treatment of gastric perforation in pigs

Cases of gastric perforation in pigs are rare in clinic. The author has encountered two cases, one case died of misdiagnosis and ineffective treatment, postmortem examination diagnosed as gastric perforation, and the other case was cured after surgical treatment. The cases cured by surgery are reported as follows:

1 clinical symptoms

A breeding Duroc boar raised by a professional household weighs about 75kg at the age of 6 months. It suddenly occurred on March 23, 2004, showing depression, loss of appetite, abdominal pain, frequent lying on the ground, and sometimes vomiting. Palpation showed pain in the abdomen, tension in the abdominal wall and groaning in abdominal pain. Shortness of breath (48 beats / min) and rapid heartbeat (88 beats / min). The body temperature is 39 ℃ and the end is cold. Because the symptoms were very similar to the previous misdiagnosed cases, abdominal puncture was performed with a cannula needle, and abdominal fluid was extracted for examination. Undigested feed residue was found and gastric perforation was suspected. With the consent of the animal owner, laparotomy was performed.

2 preoperative preparation

2.1 Open the mouth with a mouth opener and insert a gastric tube to extract gastric contents.

2.2.Intramuscular injection of Shumianxin 3mL and an injection of diazepam.

2.3 lie on your back in Baoding. The operation was performed in the lower ventral midline of the xiphoid cartilage, local shearing and general surgical disinfection.

2.4 A long longitudinal incision of 18cm was made in the operative part, the skin and muscle were cut, the peritoneum was cut and the abdominal cavity was opened.

On the right side of the pyloric gland, it was found that there was a perforation with a straight diameter of about 0.5cm, blackening around the perforation, and tissue hyperplasia and necrosis. Redness and mild adhesion of the small intestine in the right abdominal wall.

2.6 the perforation site was clamped and fixed with large hemostatic forceps, and the black, proliferative and necrotic tissue around the perforation was removed. Continuous suture was done with silk thread, and then varus suture was done.

2.7 gently peel off the partially adherent small intestine with your fingers, then rinse the intestines and abdominal cavity repeatedly with 0.9% warm sodium chloride solution until washed, and spread antibiotics in the abdominal cavity.

2.8 close the abdominal cavity. Suture the peritoneum continuously with silk thread, and suture the muscle and skin with nodules. When closing, do a drainage, place the abdominal decompression belt, and disinfect the operation part.

3 postoperative nursing

3.1 one-lap feeding. The enclosure should be kept clean, dry and quiet, and the lying parts should be covered with clean, soft bedding.

3.2 feed fresh and digestible feed, only six percent full, and keep the drinking water clean.

4 million IU of penicillin, 2 million IU of streptomycin and 20mL of antongding were injected intramuscularly twice a day for 5 days.

3.4 drainage was removed 3 days after operation.

It was observed that the pig did not eat on the first day after operation, only drank a small amount of water, began to eat a small amount in the afternoon of the second day, and then gradually improved, and the mental appetite returned to normal on the fifth day after operation. After two months of follow-up, it has been cured and successfully mated twice.

4 summary

4.1 cases of gastric perforation in pigs are rare in clinic and are easy to be misdiagnosed when confused with intestinal constipation and other diseases. If the disease is suspected, abdominal puncture is feasible, which will contribute to the diagnosis and treatment of the disease.

4.2 the cause of perforation is not clear and may be related to long-term feeding of irritating feed, rough feed, overfeeding and movements that cause a sudden increase in abdominal pressure.

4.3 if the disease can be diagnosed early and operated early, it can generally be cured.

4.4 the surgical treatment of ordinary pigs is of little significance, but breeding pigs have high economic value and therapeutic significance.
