Effect of three different needle holders on gastrointestinal anastomosis construction time and bursting pressure in equine jejunal segments

Abstract Background Equine small intestinal resection and anastomosis is a procedure where optimizing speed, without compromising integrity, advantageous. There are range of different needle holders available, but little published on the impact surgical instrumentation has technique in veterinary medicine. The objectives this study were to investigate if holder type influences construction time, bursting pressure whether influenced by time. Single layer end-to-end jejunojejunal anastomoses performed jejunal segments harvested from equine cadavers. These randomly allocated four groups. Three groups based that was used: 16.5 cm Frimand (Group 1), 16 Mayo-Hegar 2) or 20.5 3) holders. One 4) as control anastomoses. Anastomosis time recorded. Bursting determined pumping green coloured fluid progressively into lumen whilst recording intraluminal pressures. Maximum reached prior failure recorded pressure. Construction times pressures compared between holder, correlation estimated. Results not statistically ( P = 0.784).
