In Vitro Evaluation of a Closed‐Bowel Technique for One‐Layer Hand‐Sewn Inverting End‐to‐End Jejunojejunosotomy in the Horse

Abstract

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

Biomechanical comparison of four technique for pelvic flexure enterotomy closure in horses

“…After radiographic examination, all enterotomies were leak tested by air filling and immersion in a water tank. Bursting strength was tested with a modified gas inflation tank test . Briefly, a metal cannula connected to a mercury manometer was inserted at one end of the specimen and a similar cannula at the opposite end connected to a compressed air tank.…”

Post‐operative reflux – a surgeon's perspective

“…This difference was attributed to the complex design of a jejunocecostomy and poor tolerance for errors in its construction, compared with the simpler jejunojejunostomy (Freeman et al 2000). A reduction in anastomotic size from control lumen by 15-44.6% in small intestinal anastomoses (median = 28% reduction; Fig 6) appears to be regarded by some surgeons as acceptable for an end-to-end anastomosis, based on data from recent cadaver studies (Gandini 2006;Gandini and Bertuglia 2006;Nieto et al 2006;Sherlock et al 2011;Lee et al 2012;Nelson and Hassel 2014;Bracamonte et al 2014). Some of these reductions in lumen diameter approach or exceed the threshold 40% decrease in lumen diameter that reduces flow through human small intestine (Morel et al 1990).…”

Consequently, the anastomosis must allow sufficient flow of contents through it to distend the distal segment and stimulate its motility.…”
