Comparison of surgeon experience using simple interrupted and simple continuous suture patterns in intestinal resection and anastomosis.

This experimental study compared leak pressures and completion time of intestinal anastomoses performed by novice veterinarians and a Board-certified surgeon using simple interrupted and simple continuous suture patterns. Grossly normal jejunal segments ( = 108) from 6 fresh canine cadavers were used to harvest 8-cm cooled canine cadaveric jejunal segments that were randomly assigned to a control group (12 segments) and 4 treatment groups (24 segments/group, 12 constructs/group): i) simple interrupted anastomoses performed by a Board-certified surgeon (BSI); ii) simple continuous anastomoses performed by a Board-certified surgeon (BSC); iii) simple interrupted anastomoses performed by novice veterinarians (NSI); and iv) simple continuous anastomoses performed by novice veterinarians (NSC). Median (range) initial leak pressure (ILP) for control was 400.

Prospective evaluation of lymphatic embolization as part of the treatment in dogs with presumptive idiopathic chylothorax.

Objective: To describe the embolization technique and short-term clinical outcome in dogs undergoing lymphatic embolization (LE) as part of treatment for presumptive idiopathic chylothorax (IC). Additionally, to document findings in computed tomography lymphangiography (CTLa) following embolization.

Veterinary house officer perceptions of dimensions of well-being during postgraduate training.

Objective: To describe veterinary house officers' perceptions of dimensions of well-being during postgraduate training and to identify potential areas for targeted intervention.

Sample: 303 house officers.
