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.Study Design:
Healthy adult horses (n = 6).Methods:
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.Results:
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.Conclusion:
End-to-end jejunojejunostomy covered with 2 onlay MFs is not recommended because this technique results in luminal reduction.
