Colopexy of the equine large colon: comparison of two techniques   总被引:1,自引:0,他引:1  
A study was designed to evaluate 2 colopexy techniques (A and B) in 8 clinically normal horses to determine which technique would prevent recurrence of large-colon displacement and/or volvulus. For technique A, 35 cm of the lateral free band of the left ventral colon was sutured to the abdominal wall, 6 cm to the left of ventral midline. For technique B, the medial free band of the left ventral colon was sutured to the medial free band of the right ventral colon, and 8 cm of the lateral free band of the left ventral colon was sutured to the abdominal wall, 6 cm to the left of ventral midline. One horse from each group was euthanatized at 6 months, and another at 12 months after surgery. The position of the large colon, the integrity of the colopexy, and other adhesions within the abdominal cavity were evaluated. At necropsy, attempts were made to manually create displacement and volvulus of the large colon. The remaining horses in each group were anesthetized 6 months or 12 months after surgery, and the integrity of the colopexy was evaluated. After a 60-day recovery period, these horses were exercised for 2 months. Although each horse initially lost weight, the weight of all but 2 was acceptable at the conclusion of the study. Two horses that had technique-B colopexies had progressive weight loss serious enough to warrant euthanasia. Both colopexy techniques prevented manual creation of large-colon displacement and large-colon volvulus centered at the sternal and diaphragmatic flexures. Technique-A colopexy also prevented manual creation of volvulus of the large colon centered at its base.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Colopexy of the Left Large Colon to the Right Large Colon in the Horse   总被引:1,自引:0,他引:1  
Three colopexy techniques were examined in 11 normal horses to determine which would prevent recurrence of targe colon displacement and volvulus. The medial free band of the left ventral colon was sutured to the medial free band of the right ventral colon (technique A). The free band of the left dorsal colon was sutured to the free band of the right dorsal colon (technique B). In technique C, both the ventral and dorsal colon were sutured as in techniques A and B, and the pelvic flexure was sutured to the mesocolon between the right dorsal and right ventral colon. Absorbable (surgical gut) and nonabsorbable (polypropylene) suture material were compared.
One horse from each group was euthanized 2 weeks and 6 months after surgery. The position of the colon and the integrity of the colopexy were examined. At necropsy, attempts were made to produce displacement and volvulus of the colon. In the remaining horses, exploratory celiotomy 1 year after surgery was used to examine the integrity of the colopexy.
Although all horses initially lost weight after surgery, all but one began gaining weight 2 to 4 weeks later and had attained their preoperative weight by 6 months. The horse that continued to lose weight was euthanized 2 months after surgery. Numerous small colon, omental, and large colon adhesions were found at necropsy.
For all colopexy techniques, the colopexy adhesion remained short and intact at polypropylene suture sites. At surgical gut sites, the adhesion had lengthened by 6 months and was absent at 1 year. At necropsy, all colopexies prevented manual displacement of the large colon and volvulus of the colon at the sternal and diaphragmatic flexures. The colopexies did not prevent manual creation of volvulus at the base of the colon. Technique A was the easiest to perform.  相似文献

A 4 yr old, castrated male dachshund was presented for lethargy, restlessness, a "hunched" posture, and a painful abdomen. A gastric foreign body had been surgically removed 24 mo previously. Exploratory celiotomy revealed a devitalized segment of jejunum with twisted mesentery. Several adhesions and fibrous bands were present within the abdomen, presumptively from the previous gastric foreign body surgery. Histopathology determined that a fibrous tissue band caused entrapment of the segment of intestine and its mesentery resulting in volvulus and ischemic necrosis of the intestine. This case is unique because it involved a focal area of the jejunum that was incarcerated in fibrous adhesions.  相似文献

A chronic, partial mesenteric volvulus was found on laparotomy of an adult Bernese mountain dog with a 4-month history of intermittent vomiting, diarrhea, and weight loss. The dog had elevated cholestatic and hepatocellular leakage enzymes, increased bile acids, azotemia, isosthenuria, and a hypokalemic, hypochloremic, metabolic alkalosis. The dog recovered fully following reduction of the volvulus.  相似文献

A successful prophylactic permanent gastropexy was performed on a dog that had previously experienced four gastric volvulus procedures, one prophylactic pyloroplasty, and two subsequent gastric volvulus repairs. Radiographic evaluation of the previous pyloroplasty and the final permanent gastropexy are illustrated.  相似文献

Mesenteric volvulus was diagnosed in 12 dogs over a nine-year period. Each case was presented with abdominal distension and shock. Haematochezia, which is frequently reported in association with mesenteric volvulus, was present in only two of the dogs. The diagnosis, which in all cases was based on radiography, was followed by immediate treatment for shock and surgical intervention whenever possible. In five of the 12 cases, the volvulus was treated successfully and these patients survived. This indicates that the prognosis for mesenteric volvulus might be better than is currently believed, and immediate laparotomy is recommended if mesenteric volvulus is suspected.  相似文献

This report describes an unusual case of colonic volvulus associated with multiple mesenteric abnormalities. A yearling Friesian colt presented with signs of colic that persisted despite analgesia. The colt showed signs of circulatory compromise and had abnormal findings on rectal palpation. An exploratory laparotomy was performed. A complete volvulus of the ascending colon was identified associated with multiple mesenteric anomalies of unknown aetiology. The colt was subjected to euthanasia due to the extent of the intestinal damage and the likelihood of recurrence. The authors speculate that the anomalies may have been of genetic aetiology associated with a restricted gene pool.  相似文献

A one‐day‐old Thoroughbred colt foal was presented for assessment of abdominal pain and reduced urine output. Physical examination of the foal revealed marked abdominal distension, mild tachycardia, tachypnoea and congested mucous membranes. A marked anechoic peritoneal effusion, intestinal hypomotility and mural thickening of the large colon were detected sonographically. Serosanguinous fluid was obtained by abdominocentesis. After haemodynamic stabilisation, the foal underwent general anaesthesia and exploratory laparotomy and a 720° volvulus of the large colon at the sternal and diaphragmatic flexures was identified. After correction of the volvulus, the intraoperative findings were consistent with nonviability of the affected portion of the colon. The owner declined partial colon resection and elected for euthanasia of the foal. Although rare in neonatal foals, large colon volvulus should be considered in foals with signs of abdominal pain, abdominal distension and ultrasonographic findings of colonic mural thickening and luminal distension.  相似文献

Concomitant gastric and mesenteric volvulus was diagnosed in a 5-year-old Komondorok. Despite surgical correction of both displacements, the dog died 14 hours after surgery. Although gastric volvulus is a well-known syndrome in dogs, mesenteric volvulus has been reported infrequently. This report illustrates the importance of radiography in cases of suspected gastric volvulus to rule out other potential causes of acute abdominal distention, including mesenteric volvulus.  相似文献

A brachycephalic dog was presented with an acute onset of retching and abdominal discomfort. The dog had a chronic history of stertor and exercise intolerance suggestive of brachycephalic airway obstructive syndrome. Radiographs were consistent with a Type II hiatal hernia. The dog was referred and within hours of admission became acutely painful and developed tympanic abdominal distension. A right lateral abdominal radiograph confirmed gastric dilatation and volvulus with herniation of the pylorus through the hiatus. An emergency exploratory coeliotomy was performed, during which the stomach was derotated, and an incisional gastropexy, herniorrhaphy and splenectomy were performed. A staphylectomy was performed immediately following the exploratory coeliotomy. The dog recovered uneventfully. Gastric dilatation and volvulus is a potentially life‐threatening complication that can occur in dogs with Type II hiatal hernia and should be considered a surgical emergency .  相似文献

The case records of 102 cows with abomasal volvulus and 71 cows with right-side displacement of the abomasum (RDA) were examined to determine whether the preoperative base-excess concentration of the extracellular fluid could be used both as a prognostic indicator for post-operative recovery in cattle with abomasal volvulus and as an aid in differentiating between abomasal volvulus and RDA. The survival rate of cows with abomasal volvulus decreased as the base excess concentration decreased (P = 0.08); the lowest survival rate was observed in cows with base excess less than or equal to -0.1 mEq/L. There was a significant difference (0.01 less than P less than 0.025) among base excess ranges between abomasal volvulus and RDA. All cows with preoperative base-excess concentrations less than or equal to -5.0 mEq/L had abomasal volvulus, rather than RDA.  相似文献

Cecal volvulus in a ewe   总被引:1,自引:0,他引:1  
Cecal volvulus in a ewe was diagnosed and surgically treated. Clinical signs were similar to those observed in cattle with cecal volvulus. Rectal palpation, which is an important diagnostic aid in cattle, was not possible in the ewe. Thus, the decision for surgery was based on clinical signs indicative of gastrointestinal obstruction, with the diagnosis of cecal volvulus being made at the time of surgery. Recovery after surgery was rapid, and follow-up evaluation at 13 months indicated no recurrence of the problem.  相似文献

Four cases of intestinal volvulus in German shepherd dogs are described. A definitive diagnosis was achieved by exploratory laparotomy in three cases and after necropsy in the remaining animal. Clinical signs, laboratory investigations and radiological changes are reported for three of the dogs. These dogs were all euthanased. Treatment of complete intestinal volvulus is difficult. By the time the condition is diagnosed, the pathological changes are irreversible, with consequent poor prognosis.  相似文献

A previously stranded 30-kg female green turtle (Chelonia mydas) was referred to the Veterinary Medical Teaching Hospital at the University of Florida following a 2-mo history of anorexia, intermittent regurgitation, decreased fecal production, and positive buoyancy of the right side. Radiographs confirmed gaseous distension of bowel loops suggestive of intestinal obstruction. The coelom was surgically approached through a plastron osteotomy, and a 540 degrees volvulus of the small intestine was identified and derotated. An intestinal stricture was present at the site of the volvulus, and segments of bowel orad to the stricture were greatly distended. Following resection of abnormal bowel, the osteotomy was stabilized using self-tapping screws and figure-eight wire, and the defect was sealed with fiberglass cloth and fast-drying epoxy resin. A leiomyoma associated with the focal stricture was identified by histology. Appetite and defecation returned to normal. Six months after surgery, the turtle had regained normal buoyancy and showed no further clinical signs of gastrointestinal obstruction.  相似文献

An adult female dugong (Dugong dugon) was found dead and floating in Moreton Bay, Queensland, Australia. This animal was found to have a 360° mesenteric volvulus with infarction of the associated segment of small intestine, and fibrinous peritonitis. Mortality was attributed to the volvulus and its sequelae. The cause was not apparent on gross or histological examination.  相似文献

A 4‐year‐old German shorthaired pointer presented with collapse and hematochezia. Radiographs showed gas and fluid‐distended small intestines and loss of serosal detail. Ultrasound examination showed hypomotile, fluid‐distended small intestines, and thrombosed jejunal veins. Multiphasic contrast‐enhanced computed tomography was performed and showed a CT “whirl sign,” an important but nonspecific sign of intestinal volvulus in human patients. At surgery, the majority of the small intestine was entangled in the volvulus and showed black discoloration. The patient was euthanized. Postmortem evaluation yielded a diagnosis of jejunoileal mesenteric volvulus secondary to a congenital omphalomesenteric duct remnant.  相似文献

A 2-year-old Standardbred colt was examined because of signs of abdominal pain of 12 hours' duration. Clinical signs of disease, including tachycardia and abdominal distention, and rectal palpation findings of distention and thickening of the ventral colon, were consistent with displacement or early strangulation obstruction of the large colon. Surgical exploration revealed volvulus of the large colon around an axis formed by the dorsal mesenteric attachment of the transverse colon. The cecum could be completely exteriorized and lacked the cecocolic ligament and dorsal mesenteric attachments. The dorsal mesenteric attachments of the right ventral and dorsal colons were also lacking. The viscera were repositioned, and the horse was discharged 13 days after surgery. The horse developed severe colic 6 months later and was euthanatized. Mesenteric volvulus and omental adhesions were found at necropsy.  相似文献

A 10-year-old German Shepherd Dog with intermittent eructation, borborygmi, flatulence, abdominal bloating, and vomiting was found to have gastric volvulus. Gastric emptying of liquids (determined with a modified emptying-time technique) was normal. Circumcostal gastropexy vastly reduced clinical signs and resulted in weight gain.  相似文献

An 8-year-old Haflinger mare with a 10-day-old foal at foot was referred with mild abdominal pain. On the basis of clinical examination, blood and peritoneal fluid analysis, the cause of pain was suspected septic peritonitis. The horse was initially managed medically, with the horse placed in box confinement under close monitoring. No permission was given for an exploratory laparotomy, and it was decided to perform a diagnostic laparoscopy in the standing horse. The laparoscopy revealed a 360-degree anticlockwise partial duodenal volvulus of the caudal descending duodenum, which was manually reduced (hand-assisted laparoscopy). After the release, the mesentery of the duodenum showed an ischaemic band (yellowish white and dark red with a hyperaemic side) and the duodenum had a distinct ischaemic ring (orally and aborally) distinguishing the incarcerated part from the normal duodenum. Ten minutes after the release, the colour remained the same. In conjunction with the owner, it was decided to euthanise the pony. Pathology confirmed the presence of a strangulation ring and the ischaemic condition of the involved duodenum.  相似文献
