Abstract/OtherAbstract:
|
An end-to-end anastomosis was done in the center of a 5-cm devascularized jejunal segment in 5 control laboratory rabbits and 14 experimental rabbits. A second group consisted of 5 control animals and 11 experimental animals having end-to-end jejunojejunostomy in the center of a 10-cm devascularized jejunal segment. In the experimental animals, the anastomosis was wrapped circumferentially by a vascularized omental pedicle. Anastomotic leaks or fistulas developed in five 10-cm controls (100%), five 5-cm controls (100%), nine 10-cm omental wraps (82%), and four 5-cm omental wraps (29%). The remaining animals had strictures of various degrees. Injection of methylene blue into the omental vessels showed perfusion to the mucosa from the omentum. The difference between the 10-cm segment and the 5-cm segment indicates some limitation to the available blood flow from the omentum. The anastomotic stricturing was due to ischemic injury before reperfusion by ingrowth of omental vessels. A vascularized omental pedicle wrap can augment blood flow; however, the time required for neovascular ingrowth allows ischemic mucosal injury if there is no other available blood supply. |
