To compare load-to-failure results for laparoscopic absorbable fixation straps (AFSs) deployed at various angles and for AFSs versus absorbable knotless (barbed) suture when used in simulated total laparoscopic gastropexy (TLG) in specimens from cadaveric dogs.


30 stomach and abdominal body wall specimens.


Specimens were assigned to 1 of 3 groups for use in simulated TLG constructs for comparisons of load-to-failure results for single AFSs deployed at 30°, 60°, or 90° (AFS-angle group; n = 10) or for a gastropexy span of 4 to 5 cm achieved with 3-0 absorbable knotless (barbed) monofilament suture applied in a simple continuous pattern (TLG-1; 10) versus 8 AFSs applied with a deployment angle > 30° (TLG-2; 10). A 1-way ANOVA was used to compare results among AFS deployment angles (30°, 60°, or 90°) and between TLG-1 and TLG-2.


Mean ± SD load to failure for the AFS-angle group was significantly higher for the AFS deployment angles of 60° (8.00 ± 3.90 N) and 90° (12.71 ± 8.00 N), compared with 30° (5.17 ± 1.90 N). However, no substantial difference was detected in the mean ± SD load to failure for TLG-1 (39.18 ± 7.1 N) versus TLG-2 (31.43 ± 10.86 N).


Results of the present study supported the potential use of AFSs in gastropexy in dogs; however, prospective clinical research with adequate long-term follow-up is warranted before recommendations can be made.

OBJECTIVE To explore sources of serum aldosterone concentration variability in a population of healthy and diseased ferrets, determine a preliminary 1 -sided reference interval for serum aldosterone concentration in healthy ferrets, and identify a decision limit to differentiate healthy from diseased ferrets on the basis of serum aldosterone concentration.

DESIGN Prospective threshold definition and diagnostic accuracy study.

ANIMALS 78 healthy (n = 56) and diseased (22) ferrets.

PROCEDURES Serum aldosterone concentrations were measured on consecutively admitted ferrets, and an upper reference limit for aldosterone concentrations was established. Sensitivity and specificity of aldosterone concentration cutoffs to differentiate healthy from diseased ferrets were estimated with receiver operating characteristic curve analysis.

RESULTS Measurements of serum aldosterone concentrations in the ferrets showed wide variability, with a median concentration of 4.75 pg/mL (interquartile range, 0.55 to 17.9 pg/mL; range, 0.02 to 283.9 pg/mL) and 76% (59/78) of samples having concentrations < 18 pg/mL. Ferrets that were healthy, older, or sexually inactive had significantly lower aldosterone concentrations. The upper limit of the reference interval for healthy ferrets was 13.3 pg/mL (90% confidence interval, 9.9 to 16.9 pg/mL). Analysis of receiver operating characteristic curves indicated that an aldosterone concentration cutoff value of 7.6 pg/mL differentiated healthy ferrets from diseased ferrets with a sensitivity of 72.7% and specificity of 73.2% (area under the curve, 0.79; 95% confidence interval, 0.67 to 0.91).

CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that high aldosterone concentrations should not be considered diagnostic of primary hyperaldosteronism in ferrets. A need exists to develop better tests to identify primary hyperaldosteronism.
