To evaluate the effect of onlay mesenteric flaps (MFs) with end-to-end jejunojejunostomy on stomal diameter, length of jejunum with reduced stomal diameter, abdominal adhesion formation, and healing.
Experimental study.
Healthy adult horses (n = 6).
Two hand sewn end-to-end jejunal anastomoses using a 1 layer simple continuous serosubmucosal suture pattern were performed in each horse ∼ 2 and 5 m oral to the ileocecal fold. Using a random design for selection anastomosis location (oral or aboral), 1 anastomosis was covered with 2 adjacent onlay MFs secured with interrupted sutures and cyanoacrylate glue. Two weeks later, adhesion formation, stomal diameter, length of reduced jejunal stomal diameter, and healing were evaluated.
Use of onlay MFs decreased stomal diameter (P = .05), increased length of reduced peristomal jejunal diameter (P = .05), surgical time (P = .003), and serosal fibrosis (P = .05). No difference was evident for adhesion formation, and degree of inflammation between techniques.
End-to-end jejunojejunostomy covered with 2 onlay MFs is not recommended because this technique results in luminal reduction.
