Topic:Anastomosis
Anastomosis in horses refers to the surgical or naturally occurring connection between two structures, such as blood vessels or segments of the intestine. This physiological or surgical linkage is crucial for restoring or maintaining normal function following injury, disease, or surgical intervention. In equine medicine, anastomosis is often performed during procedures like intestinal resection, where a diseased portion of the intestine is removed, and the remaining ends are surgically joined. This page compiles peer-reviewed research studies and scholarly articles that explore the techniques, outcomes, and complications associated with anastomosis in horses.
Anastomotic techniques for small intestinal obstruction in horses. A scoping review. Small bowel obstruction (SBO) is a significant cause of surgery in adult horses presenting with colic pain. SBOs often require resection and anastomosis. While various techniques for intestinal anastomoses have been developed, it remains uncertain if any fully meet our clinical needs. Objective: To conduct a scoping review of publications on anastomosis techniques and outcomes for the treatment of SBO. Methods: Scoping review. Methods: A literature review was conducted using the CAB, Web of Science, Scopus, and PubMed databases. Peer-reviewed scientific articles in English, published between 1...
The effect of general anesthesia and abdominal surgery upon plasma thromboxane B concentrations in horses. To compare the effect of anesthesia alone with anesthesia and abdominal surgery on plasma thromboxane B(2) concentrations in horses. Methods: Non-randomized experimental study. Methods: Six male mixed-bred horses (5-12 years, 350 +/- 18 kg). Methods: All horses were anesthetized for 2.5 hours using halothane, and a month later abdominal surgery was performed using the same anesthetic technique with a similar duration. The schedule of anesthesia included pre-medication with diazepam (0.1 mg kg(-1) IM), followed by xylazine (2.2 mg kg(-1) IV), and 10 minutes later anesthesia was induced with ket...
Evaluation of a biofragmentable anastomosis ring for small intestinal anastomosis in ponies. Six ponies divided into two groups of three were used in a double crossover study design. Group 1 ponies had a small intestinal resection and anastomosis performed using a biofragmentable anastomosis ring (BAR); group 2 ponies had a hand-sewn small intestinal resection and anastomosis using a Gambee suture pattern. Approximately 30 days later, all ponies had a second celiotomy and anastomosed segments were removed. Group 1 ponies had a hand-sewn anastomosis performed and group 2 had a BAR. The anastomotic sites were collected at necropsy approximately 30 days later. Anastomosed intestinal segm...
Intramural hematoma in the jejunum of a mare. An intramural hematoma involving a 40-cm segment of the distal portion of the jejunum caused intestinal obstruction and colic in a mature mare. The involved intestine was resected, and an end-to-end anastomosis was performed. The mare recovered completely, but 4 years later had colic caused by incarceration and volvulus of the distal portion of the jejunum, involving fibrous abdominal adhesions. The cause of hematoma was not identified; however, rupture of an intramural vessel after migration of Strongylus vulgaris larvae was considered a possibility because of the histologic observation of an...
Diagnosis of gastroduodenojejunitis and its surgical treatment by a temporary duodenocaecostomy. Gastroduodenojejunitis is a catarrhal inflammation of the stomach and proximal portion of the small intestine. Secondary overloading of the stomach occurs so that affected horses rapidly enter a state of hypovolaemic shock which is further complicated by the presence of toxins. The condition can occur in a mild or severe form. In mild cases, conservative treatment comprising intravenous electrolyte therapy and repeated gastric decompression is indicated and is usually successful. In severe cases surgical treatment creating duodenocaecal anastomosis has given good results. This should be carrie...
Some aspects of twin-gestation in the mare. A study has been made of 44 cases of twin pregnancy in mares. The fetuses, foals, fetal membranes and blood groups of parents and foals were examined in order to determine the incidence of chorio-vascular anastomosis, blood chimaerism and freemartinism. All of the twins proved to be dizygotic and 33 of the 34 pregnancies were bicornual. Fusion of the chorion was seen in 14 of 22 placentas and macroscopic choriovascular bridges were observed in five of these, although blood chimaerism was diagnosed in 11 of 25 cases (44 per cent) examined. This would indicate a high incidence of microchoriovasc...
