The objective of this study is to evaluate the healing process of jejunal anastomosis by the aid of histopathology and
measurement of bursting pressure of anastomosis site in thirty two adult preoperatively with dexamethasone. The animals were
randomly divided into 2 equal groups: Group 1: consists of 16 dogs underwent apposition end-to-end jejunal anastomosis
using simple interrupted suture technique which in turn divided into 2 subgroups: subgroup A: consists of 8 dogs treated
preoperatively for 15 days with dexamethasone at a dose of (0.2mg/kg) given I/M. Subgroup B: control group consists of 8
dogs not treated with dexamethasone. Group 2: consists of 16 dogs underwent inverted end-to-end jejunal anastomosis using
continuous Lembert suture pattern that also divided into 2 subgroups: subgroup A: consists of 8 dogs treated preoperatively for
15 days with dexamethasone at a dose of (0.2mg/kg) given I/M. subgroup B: control group consists of 8 dogs not treated with
dexamethasone. The result of bursting pressure measurement showed higher tensile strength in the control groups (445±9.6) in
comparison with the steroidal groups (255±25.3) for both techniques. The histopathological study showed that the healing was good in all groups but the rupture that occur due to shedding the pressure lead to non discrimination between which is better in terms of healing. Massonʼs trichrome showed that collagen content of subgroups taking dexamethasone was lower than that of subgroups not treated with dexamethasone.
