title: [Revascularization of colonic anastomoses].
abstract: The revascularization of colonic anastomosis after colon segmental resection in rabbits in 9 different end-on-end and inverting suture techniques was examined macroscopically, microangiographically, micropreparatorily and histologically. Independently of the suture technique revascularization started 4 days after surgery. 8 days postoperatively the suture line is mainly bridged, 14 days postoperatively the vasal connection to the opposite side is completed. The new vessels mainly originate from the subserosal and submucosal tissue. The adhesions participate in the revascularization, too. It (the revascularization) directly correlates with the development of granulation tissue. This is evident from the excess reactive revascularization of abscesses and ulcers in the anastomoses. There always results a vascular scar in the angioarchitecture of the colonic wall. Start and extent of the revascularization cannot--in contrast to former literature--be looked at as a guarantee of quality for the healing of anastomoses.
