The objectives of the study were to describe the clinical presentation, surgical findings, complications and outcome of a case series of small and large colon obstruction by foreign bodies (FBs) in horses. The study is a retrospective case series which included 29 equids (28 horses and one donkey). Medical records of cases diagnosed with FB obstruction of the large or small colon between the years 2004 and 2016 that underwent surgery were reviewed. Data regarding signalment, clinical signs, surgical findings and post-operative variables were recorded. Short- (survival to hospital discharge) and long- (1 year after surgery) term survival rates were obtained. Cases had a mean age of 4.2 years, with both females and Arabian horses being overrepresented. Abdominal distention was the most common observation on presentation and the FB could be palpated in 20% of the cases during rectal examination. The most common reason to go into surgery was severe pain with abdominal distention. Significantly more FBs were found in the small colon during surgery (P<0.0001) and most were removed by small colon enterotomy. Complications rate post-operatively was relatively high (41%) with fever and diarrhoea being most common. Twenty-three cases (79%) were released from the hospital and all cases that were available for long-term follow-up were alive and returned to previous activity. No correlation between the chosen method of surgical removal of the FB and survival or complications post-operatively was noted. These data reflect favourable prognosis for surgical removal of colonic FBs. Few techniques are available to improve the safety of removal and the preferred method depends on the FB location, appearance and mobility. As FB obstruction resembles ‘noncomplicated’ colonic impaction, it is essential to try and recognise FB cases since deterioration can be rapid and surgery is the only sufficient treatment.  相似文献

Six horses, which had a foreign body obstruction of the small colon showed abdominal pain of progressing severity and intestinal tympany. On rectal examination the caecum and large colon were distended with ingesta and gas but the obstructing mass could be palpated in only 3 cases. All horses had elevated indirect blood pressure and in 3 there was also fluid distension of the stomach. Only one horse had known access to foreign material in the diet, but a further 3 were related to an exceptionally dry climate period. Five of the 6 horses recovered following surgery.  相似文献

The objective of this case report is to describe the diagnostic and surgical techniques for removal of a metallic foreign body in the tongue of three adult horses. The three horses were presented for evaluation and treatment of dysphagia and marked hypersalivation of 3–5 days duration. Radiographs of the head revealed the presence of a metallic foreign body in the tongue of each horse. The foreign bodies could be precisely localised under general anaesthesia using palpation and lingual ultrasonography and/or lingual radiography in combination with a forceps as a marker. The foreign bodies were successfully removed using laparoscopic instruments creating minimal soft tissue trauma. The use of long (43 cm) small laparoscopic (5 mm) instruments enabled good visualisation of the surgical field, providing optimal conditions for successful minimally invasive surgical treatment of horses with foreign bodies in the tongue. The three horses made uneventful recoveries and 12 months after surgery were eating normally and could be ridden with a bit as per usual routine. It was concluded that using long laparoscopic instruments in combination with palpation, ultrasonography and/or radiography allowed removal of the foreign body creating minimal soft tissue trauma and allowing optimal conditions for a fast recovery.  相似文献

This report describes the clinical course and surgical findings of a 5-year-old Warmblood gelding referred for colic with a previous history of intermittent colic episodes, and gastric ulcers diagnosed by gastroscopy in the preceding months. The horse underwent medical treatment but remained painful and surgery was elected. The horse underwent an exploratory laparotomy during which an impaction was identified in the transverse colon that was associated with an approximately 1 metre segment of nasogastric tube. The foreign body was removed via an enterotomy in the left dorsal colon, and the horse recovered well from surgery. No complications were encountered post-operatively.  相似文献

Objective— To report use of a magnetic retriever for arthroscopic removal of a metallic foreign body from the equine talocrural joint.
Study Design— Clinical report.
Animals— A 2-year-old Warmblood stallion.
Methods— A metallic foreign body was removed from a talocrural joint using a 10-mm magnetic retriever under arthroscopic guidance. Preoperative radiographs were used to locate the intra-articular position of the foreign body.
Results— Six months after surgery, the horse was no longer lame.
Conclusions— A magnetic retriever can be used for arthroscopic removal of metallic foreign bodies from the equine talocrural joint.
Clinical Relevance— A magnetic retriever may be useful for arthroscopic retrieval of metallic foreign bodies from synovial cavities in horses, especially when direct observation is impeded by inflamed synovial villi and fibrin.  相似文献

A 13-year-old mare presented for evaluation of recurrent colic episodes. The horse was diagnosed with a mass within the spleen at the ultrasound examination of the abdomen; the levels of Serum Amyloid A and the fibrinogen were high and so a presumptive diagnosis of an abscess involving the spleen was made base on clinical, ultrasonographic and laboratory findings and it was decided to perform n exploratory laparotomy for a definitive diagnosis and possible treatment. Upon abdominal exploration a mass involving the spleen, the lateral wall of the ventral colon adherent to the left abdominal wall was diagnosed and with an intraoperative ultrasound examination a linear hyperechoic foreign body was diagnosed within the mass. It was removed through an enterotomy of the left ventral colon that allowed the digital exploration of the mass without spilling of pus within the peritoneal cavity. The horse was discharged and the long term follow-up revealed no complications and no more signs of abdominal pain.  相似文献

Objective: To describe a novel surgical technique for management of right dorsal colitis in the horse. Study Design: Clinical report. Animals: 14‐year‐old Warmblood gelding. Methods: The horse was referred for treatment of a stromal abscess and signs of right dorsal colitis. Plasma chemistry revealed marked hypoproteinemia. Abdominal ultrasonographic examination showed a thickened right dorsal colon (RDC). Medical treatment was unsuccessful. With the horse in left lateral recumbency under general anesthesia, an approach to the right side of the abdomen through a 16th rib resection was made. The thoracic cavity was entered during the approach. Surgical resection of the RDC and side‐to‐side anastomosis of the diaphragmatic flexure to the small colon (bypass) was performed. The thoracic cavity was closed by attaching the diaphragm to the body wall and air was removed at the completion of surgery. Results: Resection of the RDC and bypass of the resected area was successfully performed. The colic signs and hypoproteinemia resolved. Complications of surgery included a deep surgical site infection with development of a large intrathoracic abscess. The abscess was managed with drainage and long‐term antimicrobial treatment. Conclusion: Right dorsal colitis can be treated successfully with resection and bypass of the RDC. In cases where the thoracic cavity is penetrated during the abdominal approach, the diaphragm should be sutured to the body wall at the beginning of surgery to avoid development of an infection within the thoracic cavity. Clinical Relevance: RDC resection and bypass may be an alternative approach for management of horses with right dorsal colitis.  相似文献

A mare was presented for evaluation of a penetrating thoracic injury. Surgical exploration of the thoracic wound was performed, revealing diaphragmatic perforation and the presence of a foreign body lodged in the right dorsal colon. The foreign body was removed through the thoracic deficit, the colon repaired and the thoracic wound closed utilising a latissimus dorsi muscle flap. It can be concluded that successful management of thoracic wounds with concurrent abdominal viscera involvement is achievable if minimal contamination is evident. In addition reconstruction of large thoracic defects with primary muscle flaps is a viable option in the horse.  相似文献

While playing or simply because of avidity, dogs may ingest a variety of foreign bodies. Ingested foreign bodies, which are not stopped in the mouth or oesophagus, enter into the stomach. Once a foreign body has passed through the pylorus, jejunum and ileum appear to be the most common sites of the small intestine obstruction. The records of 103 cases, treated at the Clinic for Surgery, Orthopaedics and Ophthalmology of the Veterinarian Faculty, University of Zagreb from January 1981 till December 1998 were analysed. The analysis included the incidence of ileus caused by foreign bodies and the distribution of patients by sex, age, breed, duration of illness, site of obstruction, types of foreign bodies and the interrelation between these parameters. The results of our research show that the number of patients with foreign body induced ileus is increasing. Males ingested foreign bodies more often than females. Foreign body induced ileus was more frequently found in animals below 2 years of age. Foreign bodies were mostly ingested by mongrels, but also by popular dog breeds such as Dobermanns, Poodles, Cocker Spaniels and Rottweiler. Most of these ileus cases were found in March and October and the predominant clinical signs included anorexia, dehydration, abdominal tenderness and absence of defecation. The most common site of small intestine obstruction by foreign bodies was the jejunum, and the most effective treatment was enterotomy. Dogs mostly ingested stones, plastic and rubber objects. The treatment was more successful in dogs below 2 years of age. Patients that died post-surgically, died mostly the first day after surgery.  相似文献

OBJECTIVE: To report our experience with horses that presumptively had severe intraluminal hemorrhage from enterotomy or anastomosis. STUDY DESIGN: Clinical study. ANIMALS: Six adult horses and 1 adult donkey. METHODS: A retrospective study was conducted at the University of Illinois (April 1994 to December 2001) to determine the clinical course and outcome of horses with melena and/or anemia and evidence of life-threatening hemorrhage from intestinal incisions. Medical records of all horses that had colic surgery were reviewed to determine the proportion of horses with this complication. In addition, horses that fit the same criteria identified in 3 other veterinary clinics were included. RESULTS: Three horses (1.3%) of those that had enterotomy or anastomosis at the University of Illinois and 4 horses from other clinics had complications presumptively related to severe hemorrhage from these intestinal procedures. Melena became evident within 72 hours of surgery and lasted 12 to 96 hours. Six horses had an acute and severe drop in packed cell volume (PCV), increased heart rates, and other signs of acute hemorrhage, and 1 horse had signs of colic postoperatively. Horses were administered intravenous formalin (3 horses) and whole blood transfusions (4 horses). Repeat celiotomy was performed on 2 horses. In 1 of these horses, a bleeding artery was ligated in the edge of the original enterotomy, and, in the other, a 25-cm-diameter intraluminal blood clot was found occluding the pelvic flexure. A horse that had jejunocolostomy for cecal impaction was not treated for hemorrhagic shock but was euthanatized and necropsied. Necropsy revealed blood-filled bowel from the jejunocolostomy to the anus. One of the remaining 6 horses died of enterocolitis and 5 survived to discharge. CONCLUSIONS: Hemorrhage from incisional edges, particularly in the large intestine, should be considered a rare but possibly fatal complication of enterotomy or anastomosis in horses. CLINICAL RELEVANCE: To prevent fatal hemorrhage from incisional edges during enterotomy or anastomosis, large vessels should be ligated at the original surgery, and hemostatic effects of different closure techniques should be considered. No intraoperative or postoperative findings were useful to predict this complication, and response to supportive medical therapy was favorable.  相似文献

The history, clinical signs, results of diagnostic imaging, treatment methods and outcome of 16 adult horses with a metallic foreign body in the tongue are reviewed. All the horses had a swollen tongue, they salivated excessively and were partially to completely anorexic. Less common clinical signs were fever, an enlarged and painful intermandibular space, dysphagia, unilateral tongue paralysis and halitosis. Most of the horses had shown clinical signs for less than 24 hours. The foreign bodies were diagnosed by oral examination, radiography and ultrasonography; they were removed from the tongue of four of the horses during the initial oral examination, and were removed surgically from nine others; the other three horses were treated medically without attempts being made to extract the foreign bodies. Twelve of the bodies were small pieces of wire and one was a hypodermic needle. All the horses received a combination of antimicrobial and non-steroidal anti-inflammatory drugs and they all made an uneventful recovery. Feeding hay and the use of cable-framed tractor tyres as feeders were commonly associated with the cases.  相似文献

Gastric surgery is commonly performed to remove foreign bodies and correct gastric dilatation-volvulus and is less commonly performed to treat gastric ulceration or erosion, neoplasia, and benign gastric outflow obstruction. Intestinal surgery, although commonly performed by veterinarians, should never be considered routine. The most common procedures of the small intestinal tract performed in dogs and cats include enterotomy and resection/anastomosis. Surgery of the large intestine is indicated for lesions causing obstruction, perforations, colonic inertia, or chronic inflammation.  相似文献

Common causes of obstruction of the small colon and rectum include diffuse faecal impaction, enterolithiasis, faecalithiasis, phytobezoar, trichobezoar, phytotrichobezoar, phytoconglobate, foreign body, intramural haematoma and retained meconium. Poor dentition, poor-quality hay, lack of adequate water, parasite damage and lack of exercise are risk factors for the development of small colon impactions. Clinical signs of small colon obstruction develop slowly because a large space proximal to the obstruction allows ingesta, gas and fluid to accumulate. Medical management of horses with faecal impaction of the small colon involves improvement of hydration, stimulation of colonic motility, softening the impaction by the administration of osmotic laxatives or lubricants, and control of pain. Surgical intervention is indicated when medical management fails to resolve the impaction or when intractable pain and a deteriorating cardiovascular status ensues.  相似文献

Caecocolic intussusception is an uncommon cause of colic in the horse. Surgical correction presents its own set of challenges. The affected tissue is often markedly oedematous and a partial typhlectomy through an enterotomy incision in the right ventral colon can be the only method of successfully reducing the intussusceptum. Suture ligation of the nonviable portion of caecum can result in cut through of tissue, which can lead to an insecure ligation. In addition, a right ventral colon enterotomy can result in life‐threatening peritoneal contamination. This report describes the novel use of polyamide tie‐wraps to ligate the inverted caecum, allowing for partial typhlectomy and reduction of the intussusceptum, as well as a method to minimise potential abdominal contamination. To the author's knowledge, this is the first report of the use of polyamide tie‐wraps in the gastrointestinal tract of the horse.  相似文献

CASE DESCRIPTION: 3 Horses were examined and treated because of sudden onset of signs of abdominal pain. CLINICAL FINDINGS: All horses had a retrosternal (Morgagni) hernia involving the right side of the diaphragm. In each horse, the large colon was incarcerated in a right muscular defect in the diaphragm with a large hernial sac. TREATMENT AND OUTCOME: Definitive surgical repair of the hernia was not performed during the initial celiotomy. The hernia was repaired with mesh herniorrhaphy, but without resection of the hernia sac in 2 horses. For 1 horse, conservative management was applied. In the 2 horses treated with surgical correction, no major postoperative complications developed, and all 3 horses have been free of signs of abdominal pain. CLINICAL RELEVANCE: Horses with retrosternal hernias involving the diaphragm can develop clinical signs of intermittent obstruction of the large colon and chronic colic. In horses, retrosternal diaphragmatic hernias appear to develop exclusively in the right ventral aspect of the diaphragm and could represent an embryologic defect of diaphragm formation. Affected horses can be successfully treated with mesh herniorrhaphy or, in some instances, with conservative management.  相似文献

Seven horses with metallic foreign bodies in the mouth or pharynx were examined at the Colorado State University Veterinary Teaching Hospital from 1983 to 1989. The horses had variable clinical signs, such as purulent nasal discharge, swelling of the throatlatch area, and dyspnea. Most of the horses had clinical signs for more than 2 weeks, and had no or only temporary improvement with conservative medical treatment (antibiotics, nonsteroidal anti-inflammatory drugs). The definitive diagnostic test in all of the cases was radiography, which also aided in the plan for surgical removal of the foreign body. Once the foreign body was removed from each of the horses, their clinical signs resolved. Most of the foreign bodies were small pieces of wire, the sources of which could not be determined, but that may have been incorporated in baled hay.  相似文献

OBJECTIVE: To report on the outcome of surgical treatment of acute abdominal crises in miniature breed horses. DESIGN: Retrospective case series of miniature horses presented to the University Veterinary Centre, Camden with an acute abdominal crisis. METHODS: Hospital records of all miniature horses that underwent ventral midline laparotomy for acute abdominal crisis between 1997 and 2001 were reviewed. The signalment, history, clinical signs, results of ancillary diagnostic procedures, location and type of intestinal lesion, treatment and outcome were retrieved from each case record. Long-term survival was determined by telephone interview of owners. RESULTS: Eleven miniature horses including five females and six males underwent ventral midline laparotomies for acute abdominal crisis during the study period. Ages ranged between 1 month and 19 years. Surgical findings included faecalith obstruction (seven horses), enterolith (one horse), strangulating lipoma of the descending colon (one horse), jejunal infarction (one horse), and caecal infarction (one horse). Long-term survival rate (minimum 12 months post surgery) was 55%. Six of eight horses with simple intraluminal obstructions survived, while the three horses with gastrointestinal lesions associated with vascular compromise were euthanased either at surgery (caecal infarction), or postoperatively, due to complications (strangulating lipoma of the descending colon, jejunal infarction). Postoperative complications in this study included impaction of the descending colon (two horses), diarrhoea (two horses), peritonitis (one horse), hyperlipaemia (two horses), incisional infection (two horses) and abdominal adhesions (one horse). Hyperlipidaemia was present in five of seven horses in which serum triglycerides were measured at presentation. CONCLUSIONS: Simple intraluminal obstructions of the large intestine were frequently encountered during exploratory laparotomy in miniature horses presented for acute abdominal crises, and their surgical treatment was associated with a good prognosis. In contrast, this study suggested that abdominal pain associated with vascular compromise of gastrointestinal tissues in miniature horses was associated with a poorer prognosis, consistent with reports in other horse breeds. Possible contributing factors to faecalith formation, including poor quality roughage, dental disease, and inadequate water consumption, should be recognised and avoided in miniature horses. Serum triglyceride concentrations should be measured in miniature horses presented for acute abdominal pain. If elevated, nutritional supplementation should be provided.  相似文献

Studies in horses with experimental gastrointestinal fistulas may lead to rapid advancements in equine nutrition, as well as prevention and treatment of diseases such as colic and laminitis. The aim of this study was to devise a technique and a cannula to create a large fistula in the right dorsal colon (RDC). A total of 13 horses with normal gastrointestinal tract were used. After the administration of sedatives and local anesthetics, a segment of the right 16th rib was removed, a circular defect was created in the muscular wall, and the RDC was sutured to the muscular wall. The subcutaneous tissue and skin were closed over the attached RDC in eight horses (closed technique), or removed to expose the serosa of the colon sutured to the abdominal wall in five horses (open technique). A full thickness circular incision was made 2 to 6 weeks later to create a fistula. A cannula (diameter, 5 cm) made of natural rubber or silicon was inserted in the fistula. The open surgical technique was easier to perform and resulted in fewer complications. The cannula made of silicon resulted in less pruritus. One horse had a large colon torsion around the colopexy before fistula creation. One of the 12 fistulated horses had a large colon displacement 43 days after cannula insertion. These observations suggest that pexis of the RDC may predispose the horse to large colon displacement or volvulus. The open technique for the colopexy and the cannula made of silicon can be used for creation of a RDC fistula.  相似文献

Hepatic abscesses were diagnosed in 3 adult horses. Two were < 4 years old and had evidence of concurrent immune-mediated conditions, including aseptic arthritis, immune-mediated thrombocytopenia, and immune-mediated anemia. Predisposing factors for hepatic abscess formation in these horses included prior abdominal surgery, proximal duodenitis/jejunitis, inflammatory bowel disease, and a penetrating foreign body in the large colon. Serum hepatic enzyme activities were within or slightly greater then reference limits in all 3 horses. The most pronounced and consistent abnormalities on CBC and serum biochemical analyses were hyperproteinemia, hyperglobulinemia, and a decreased albumin-to-globulin concentration ratio. Hepatic ultrasonography identified hepatic abscesses in all 3 horses. A variety of bacteria were isolated from these abscesses, including Staphylococus aureus and Bacteroides fragilis. One horse developed septic tibiotarsal arthritis, presumably as a result of intermittent bacteremia. Despite aggressive medical treatment, all horses were euthanatized because of a worsening condition and poor prognosis.  相似文献
