Abstract

Objective— To report a technique for closed-bowel 1-layer inverting end-to-end jejunojejunal anastomosis in horses.

Study Design— Experimental study.

Sample population— Fresh cadaveric jejunal segments from 12 horses.

Methods— For each bowel segment a 1-layer closed and a 2-layer inverting end-to-end jejunojejunosotomy was created. Anastomosis construction time and anastomotic bursting pressure were measured and compared.

Results— Closed-bowel anastomosis was significantly faster to create than a 2-layer technique. Luminal narrowing (<30%) was similar with both techniques and comparable with other inverting techniques. Bursting pressure was significantly higher for the 2-layer technique, although all anastomoses resisted pressures higher than those reported for other jejunojejunal anastomosis techniques.

Conclusions— A 1-layer hand-sewn, closed, inverting jejunojejunosotomy using a modified Doyen clamp was easy and faster to perform, and resulted in functional characteristics similar to, a 2-layer hand-sewn inverting technique.

Clinical Relevance— A closed, 1-layer inverting technique could be considered for equine jejunal anastomosis but requires in vivo evaluation before recommendation for clinical use.
