Medical records of 35 cattle with small-intestinal volvulus were reviewed. Surgical correction was performed on 32 cattle, and 17 of these cattle were discharged from the hospital. Mean duration of clinical signs for survivors was not significantly different from that for nonsurvivors, and the most commonly recorded clinical signs were abdominal pain, anorexia, lethargy, abdominal distention, and dehydration. Physical examination of cattle with intestinal volvulus revealed tachycardia, tachypnea, and normothermia. Rectal examination findings included distended small intestine, scant feces or mucus, and tight bands coursing dorsoventrally in the middle portion of the abdomen. Clinicopathologic testing revealed azotemia, hypocalcemia, hyperglycemia, and leukocytosis with a left shift. Nonsurvivors had significantly lower mean preoperative venous blood pH and mean base excess and higher mean serum potassium concentration than did survivors. A diagnosis of volvulus of the entire small intestine was made during surgery in 25 cattle, whereas volvulus of the distal jejunum and ileum was diagnosed during surgery in 7 cattle. Survival rate following surgical correction of volvulus of the entire small intestine (44%) was not significantly different from survival rate following surgical correction of volvulus of the distal jejunum and ileum (86%). However, survival rate for dairy cattle (63%) was significantly higher than survival rate for beef cattle (22%). To determine potential risk factors for the development of small-intestinal volvulus, epidemiologic data from cattle admitted to veterinary teaching hospitals throughout North America were collected by searching records entered into the Veterinary Medical Data Base.(ABSTRACT TRUNCATED AT 250 WORDS)

Abnormal phosphorus homeostasis occurs in dairy cows with an abomasal displacement or volvulus. The goal of this study was to identify potential mechanisms for hypophosphatemia and hyperphosphatemia in cows with a left displaced abomasum (LDA), right displaced abomasum (RDA), or abomasal volvulus (AV). Accordingly, the results of preoperative clinicopathologic analyses for 1,368 dairy cows with an LDA (n = 1,189), RDA, or AV (n = 179) (data set 1) and for 44 cows with an AV (data set 2) were retrieved. Laboratory values were compared by Student's t-tests, and correlation and regression analyses were performed. Thirty-four percent of the animals from data set 1 (463/1,368) were hypophosphatemic (serum phosphorus concentration ([Pi]) < 1.4 mmol/L), and 9% (122/1,368) were hyperphosphatemic ([Pi] >2.3 mmol/L). Serum [Pi] was significantly lower (P < .05) in cows with an LDA (1.60 +/- 0.53 mmol/L; mean +/- SD) than in cows with an RDA or AV (1.85 +/- 0.68 mmol/L). For cows with an LDA, [Pi] was correlated with serum urea nitrogen concentration ([SUN]) (r = 0.34) and serum concentration of magnesium ([Mg]) (r = 0.20). For cows with an RDA or AV, linear correlations existed between [Pi] and [SUN] (r = 0.45), [Mg] (r = 0.43), and serum chloride concentration ([Cl]) (r = -0.27). Stepwise logistic regression analysis indicated that low [SUN] and the diagnosis of an LDA had the strongest associations with hypophosphatemia. In cows with hyperphosphatemia, [Pi] was most strongly associated with azotemia. In cows with an AV, the strongest correlations with [Pi] were found for [SUN] and serum creatinine. We conclude that hypophosphatemia in cows with an LDA is primarily due to decreased feed intake. In contrast, hyperphosphatemia in cattle with an RDA or AV appears to result from dehydration and decreased renal blood flow.

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.
