Anastomotic leak is the most devastating complication after colorectal surgery, and the blood supply is a very important factor in anastomotic healing. Papaverine is a vasodilatory and antispasmodic agent which has been used in many ischemic conditions because of its potentially protective effects. The aim of this study is to investigate the effects of papaverine on healing colon anastomosis.
Forty 8‑ to 10-week-old female Wistar Albino rats were used in this study. Rats were randomized into 4 groups: control group; ischemia-reperfusion and anastomosis group; ischemia-reperfusion and anastomosis + intraperitoneal one dose papaverine group; and ischemia-reperfusion and anastomosis + intraperitoneal daily (10 days) papaverine group. Anastomotic bursting pressures, the hydroxyproline measurements and macroscopic adhesion gradings were evaluated.
There was a significant difference between papaverine-administered groups and ischemia-reperfusion and anastomosis group for anastomotic bursting pressures, hydroxyproline measurements and macroscopic adhesion grading (p < 0.05).
In the rat model, papaverine had a favorable effect on anastomotic healing.
