{Abstract}: After colorectal surgery, anastomotic leakage is a major cause of mortality and morbidity. There are many factors affecting anastomotic leakage. It is known that agents such as neostigmine that is used to reverse neuromuscular blockade have certain effects on anastomosis. In our study, in which we planned to test this hypothesis, we aimed to compare the possible effects of different doses of sugammadex and neostigmine on colon anastomosis strength in a colonic resection anastomosis model in rats.<BR>Forty adult Wistar albino male rats were divided into five groups as control (group C), Sugammadex 16 mg/kg (group SL), sugammadex 96 mg/kg (group SH), neostigmine 0.3 μmol/kg (group NL), and neostigmine 1.5 μmol/kg (group NH). The transverse colons of all rats were resected, and colonic anastomosis was performed. Appropriate drug doses according to the groups were given on the postoperative seventh day, and tissue hydroxyproline (TH) level and anastomotic bursting pressure were measured.<BR>Anastomotic bursting pressure values were statistically significantly different between the groups (P = 0.001). The bursting pressure in group SH was significantly higher compared with group C, group NL, and group NH. The hydroxyproline values were statistically significantly different between the groups (P = 0.015). According to the post hoc test results, the difference was between group SH and group C (P = 0.007). There were no significant differences between the other groups (P > 0.05). There was no significant difference in terms of intra-abdominal adhesion rates between the groups.<BR>In our study, we found that low and high doses of neostigmine had no variable effect on anastomosis, but high dose of sugammadex (96 mg/kg) had an increasing effect on intestinal anastomosis strength.
