Ex vivo comparison of full-thickness biopsy techniques in the equine small intestine.

Objective: To compare the practicability and tissue sample quality between different intestinal biopsy techniques.

Study Design: Experimental, randomized ex vivo study.

Sample Population: Small intestine of nine horses.

Flowmetry and spectrophotometry can detect reduced intestinal microperfusion in nonsurvivors during equine colic surgery for large intestinal strangulation.

Objective: To evaluate the use of laser Doppler flowmetry and spectrophotometry (LDFS) for large intestinal viability assessment in horses with naturally occurring large intestinal strangulations.

Methods: By use of LDFS, intestinal microperfusion was quantified as tissue oxygen saturation (tSo2), hemoglobin (tHB), and blood flow (tBF) in cases with large colon volvulus and small colon strangulations undergoing colic surgery (n = 17). Intestinal biopsies were taken from the pelvic flexure in all large colon cases and in small colon cases that underwent intraoperative euthanasia.

Flowmetry and spectrophotometry for the assessment of intestinal viability in horses with naturally occurring strangulating small intestinal lesions.

Background: Ancillary diagnostic methods to enhance the accuracy of viability assessment have not been established for use in clinical practice.

Objectives: To assess intestinal microperfusion measured by Laser Doppler Flowmetry and Spectrophotometry (LDFS) in naturally occurring small intestinal strangulations of different origins and to compare this between viable and non-viable segments.

Study Design: Prospective clinical trial.

Measuring tissue oxygen saturation in the orad intestinal segment during equine colic surgery may aid in predicting the occurrence of postoperative ileus.

Objective: To assess the histological injury and intestinal microperfusion measured by laser Doppler flowmetry and spectrophotometry (LDFS) of the small intestine orad to a strangulation during colic surgery.

Animals: Horses with naturally occurring small intestinal strangulations undergoing colic surgery were included.

Methods: In this prospective clinical trial, intestinal tissue oxygen saturation (tSO2) and tissue blood flow (tBF) were measured by LDFS orad to the strangulation following release of the strangulation (n = 18).

Osteoarthritis of the coxofemoral joint in 24 horses: Evaluation of radiography, ultrasonography, intra-articular anaesthesia, treatment and outcome.

Background: Few case reports describe equine coxofemoral joint osteoarthritis (CFJOA).

Objectives: To evaluate diagnostic findings and outcome of horses with CFJOA and to provide a score facilitating radiographic assessment.

Study Design: Retrospective case series.
