[Influence of lymphostasis on healing processes of intestinal anastomoses. Experimental research].
The Authors studied the healing of the intestinal anastomoses in rats with mesenteric and celiac lymph-vessels coagulated and cut. The experiment was realized utilizing 104 rats, divided in fours groups: after the induction of the lymphostasis, in the first group an end-to-end ileal anastomosis was made by polyglycolic acid suture, 6/0 in diameter. The control groups consisted of rats with ileal anastomoses, with lymphostasis solely and sham operated. The macroscopic observation and the histological findings were studied 7 and 14 days after the anastomoses' performance. Only in the animals with lymphostasis was observed an anastomosal leakage of 19% at 7th day control. In the same period the histologic sections showed a modified anastomosal healing, related to the significant reduction of the granulomatous tissue formation in presence of the lymphostasis.
