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

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

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

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

Eighteen dogs were divided into three groups, each containing three volvulus and three control dogs. The stomachs of the volvulus dogs were rotated 360°, sutured in position, and kept decompressed by a Foley catheter placed in the fundus. Control dogs underwent the same manipulation, except that the stomach was replaced to normal position. One dog in each group was evaluated at 4, 8, and 12 hours. Evaluation consisted of SC46 microsphere injection to determine percent cardiac output to various stomach regions, and gross and microscopic changes in the stomach and other tissues drained by the portal system. Cardiac output to the control stomachs exceeded the volvulus stomachs by fivefold. Time was not a significant factor. Edema was present throughout the volvulus stomach. The most severe histologic changes, such as hemorrhage, were seen in the greater curvature of volvulus stomachs. Other portal tissues were grossly and histologically normal. Three additional dogs were evaluated 1 week after creation and reduction of a 12 hour volvulus; the stomachs were normal indicating reversibility of pathologic changes. This study demonstrates abnormal blood flow in rotated nondistended stomachs. Anatomic repositioning should take place as soon as possible in the treatment of gastric dilation volvulus. 相似文献

Equine Large Intestinal Volvulus A Review of 124 Cases 总被引：2，自引：0，他引：2
The average age of 122 horses with ascending colon volvulus was 6.6 +/- 0.4 years. Gastric reflux was a presenting sign in 35% of the cases. Peritoneal fluid protein levels had a mean of 2.54 +/- 0.14 g/dl and 20 horses had grossly normal peritoneal fluid at the time of presentation. Ascending colon volvulus was most commonly found at the level of the cecocolic fold with the initial ventral colon movement in a dorsomedial direction about the ascending mesocolic axis. The overall survival rate was 34.7% with a recurrence rate of only 4.9%. 相似文献

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

Strangulating volvulus of the ascending colon in horses 总被引：2，自引：0，他引：2

Of 57 horses with strangulating volvulus of the ascending colon, 42 were mares (including 21 postparturient mares), 8 were stallions, and 7 were geldings. Volvulus occurred most frequently in the summer (n = 24) and spring (n = 17). Pain was evaluated as severe in 41 horses, moderate in 9, and mild in 4. The abdominal fluid from 30 horses varied from clear yellow in 19 horses, to cloudy yellow in 3 horses, and serosanguineous in 8 horses. Protein content and nucleated cell count in the abdominal fluid were 2.5 +/- 1 g/dl and 1,000 +/- 900 microliters, respectively. Fifty horses had greater than or equal to 360 degrees volvulus and 7 had a 270 degrees volvulus, with 49 occurring in a counterclockwise direction. The site of volvulus in all horses was at the mesenteric attachment of the colon, except for a 360 degrees volvulus at the sternal and diaphragmatic flexures in 1 horse. Survival rates for horses with a greater than or equal to 360 degrees and a 270 degrees volvulus were 36% and 71%, respectively. The difference in survival rates reflected the severe vascular occlusion in the colon of horses with greater than or equal to 360 degrees volvulus. In nonsurvivors, hemorrhage in the submucosa and lamina propria (P less than 0.005) and edema in the submucosa (P less than 0.01) were greater than those in survivors. In nonsurvivors, greater than 97% of the superficial epithelium was lost. In horses that survived, only 60% of the cells were lost or degenerated.(ABSTRACT TRUNCATED AT 250 WORDS) 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

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

BACKGROUND: Mesenteric volvulus describes a torsion of the small intestine around the mesenteric root, which can be partial or complete. In dogs, it is an uncommon condition, with German shepherd dogs showing a predisposition. Chronic mesenteric volvulus has also been described. In cats, previous reports have documented two cases of small intestinal volvulus, both diagnosed at necropsy, and a further case of volvulus of the colon in a patient that died after surgery. CLINICAL SIGNIFICANCE: This report describes two cats with mesenteric volvulus that were successfully treated. To the authors' knowledge, no reports of antemortem diagnosis or treatment of small intestinal volvulus in cats have previously been published. On the basis of the cases presented, it appears that the diagnosis of intestinal volvulus may be more difficult in cats than in dogs, but that the prognosis may not be as poor. Therefore, it is suggested that owners be encouraged to pursue surgery. 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

Ten horses were euthanatized before, during, or after surgery to correct severe volvulus of the large colon. At surgery, the colonic serosa changed from blue-gray, blue or purple toward a more normal pink in seven horses after the volvulus was corrected. The mucosa consistently remained black or dark red. Results of postmortem colonic microangiography revealed perfusion of the serosa and the circular and longitudinal muscle layers, but mucosal perfusion was limited by thrombosis in the muscularis mucosae and submucosa. There was evidence of thrombosis of the mesenteric colic vessels in six horses. Damage to the colonic vascular system, especially thromboembolism in the submucosa, may be an important limitation to colonic viability after surgical correction of volvulus of the large colon. 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

Nonsurgical correction of a renosplenic entrapment of the large colon was attempted in a mare, using a rolling technique. After correction, the mare had initial improvement in clinical signs, but later developed signs of abdominal discomfort. A ventral midline celiotomy was performed, and a pelvic flexure impaction and large intestinal volvulus were found and corrected. 相似文献

The records of 84 cows with cecal dilatation or cecal volvulus were reviewed. The diagnosis was made by exploratory laparotomy or necropsy in 21 cows with cecal dilatation, and in 45 cows with cecal volvulus. Eighteen of the cows with cecal dilatation responded to medical management and the diagnosis was made by physical examination alone. The most useful criteria for determining that surgery was necessary were the presence of a high heart rate, apparent abdominal pain, scant or absence of feces, and the apex of the cecum rotated cranially on rectal examination. The prognosis for cattle with cecal dilatation and volvulus was good following medical therapy or decompression at surgery unless there was severe vascular compromise of the cecum. There was a 10% recurrence rate, and in these cows a partial typhlectomy was performed. 相似文献

Seventeen cows with right displacement of the abomasum (rda) without abomasal volvulus, nine cows with abomasal volvulus and 10 clinically healthy cows were examined ultrasonographically. A 5.0 MHz transducer was used to scan the eighth to 12th intercostal spaces and the cranial and caudal aspects of the flank on the right side. The position, size and dorsal and ventral margins of the abomasum were determined at each imaging position. In both groups of diseased cows, the ventral abomasum contained fluid ingesta, which appeared hypoechogenic with diffuse echogenic stippling. The abomasal folds could be seen clearly as echogenic sickle-shaped structures within the ingesta. The dorsal abomasal gas cap varied in size and was characterised by reverberation artefacts, which appeared as echogenic lines running parallel to the body surface. Compared with the healthy cows, the abomasum was larger and located significantly closer to the midline of the dorsum in both groups of cows. Compared with the cows with rda, the abomasum in the cows with abomasal volvulus was significantly smaller in the eighth intercostal space and significantly larger in the 11th intercostal space. It was not possible to differentiate between rda and abomasal volvulus on the basis of the ultrasonographic findings. 相似文献

Small bowel volvulus was diagnosed in six dogs. Peracute onset, hematochezia, and lack of vomition were the most prominent clinical features. All affected dogs exceeded 23 kg in body weight. Five of the six dogs were males and two were German shepherd dogs.
There were no diagnostic findings that were specific for intestinal volvulus. Abdominal radiographs in two dogs were interpreted as showing "pathologic" dilatation of bowel. However, it could not be determined whether the dilatation was caused by adynamic ileus or by mechanical obstruction. Results of hematological tests help to differentiate other causes of bloody diarrhea such as hemorrhagic gastroenteritis and parvovirus enteritis.
Prognosis for dogs with intestinal volvulus was poor: all six of the dogs in our series died. 相似文献

Duodenal volvulus is an unreported cause of colic in the horse. This case report describes a 15‐year‐old Warmblood gelding evaluated for acute abdominal discomfort. Exploratory celiotomy revealed duodenal volvulus and gastric rupture resulting in severe, acute, septic peritonitis. To the authors' knowledge, this is the first report of a volvulus of the equine duodenum. 相似文献
