It is well known that ovarian torsion is a medical emergency and its nowadays treatment requires the removal of the torsion as soon as possible in order to restore the blood flow and to avoid necrosis, but the detorsion is accompanied by an increase in oxidative lesions that worsen the initial damages due to ischemia only. Our purpose was to check the efficiency of the controlled reperfusion method in the experimental torsioned ovaries, in reducing the reperfusion injuries due to oxidative stress. The study was approved by The Research Ethics Committee (08.02.2016). An experimental study which involved 70 healthy female rats (Rattus albicans) that were randomized by 10 animals into 7 groups. 1st group: no intervention. 2nd group (sham): only laparotomy. 3rd group (ischemia): the animals were exposed to ovarian ischemia that lasted 3 hours. Ischemia was assured by twisting the ovaries 3 times clockwise, fixing them to the abdominal wall. 4th and 6th group: 3 hours ovarian ischemia and 1 hour (for 4th group) and 24 hours (for 6th group) of simple reperfusion. 5th and 7th group: 3 hours ovarian ischemia and 1 hour (for 5th group) and 24 hours (for 7th group) of controlled reperfusion. The controlled reperfusion method was applied for the first 2 minutes from the reperfusion period by opening and closing the clips (10 seconds for each of the maneuver) on the ovarian pedicles, followed by simple reperfusion for 1 and 24 hours. AGEs (advanced glycation end products) levels were measured in ovarian homogenates by SÉRO Luc, et al. method (2013). The results were analyzed using Welch's ANOVA. Ischemia determined a statistically significant increase in AGEs levels in ovarian homogenates in ischemia gro compared to no intervention group (p=0,031) and sham group (p=0,047). The reperfusion groups registered augmentation of AGEs compared to ischemia group, without significant difference between simple and controlled reperfusion at 1 hour (p=0,059), and with significant decrease after 24 hours of controlled reperfusion compared to simple reperfusion groups (p<0,001). As AGEs are known to be produced in oxidative stress conditions, our results point out that ovarian torsion is a disease where oxidative modification of molecules occur. Controlled reperfusion could protect the organ from oxidative stress during the reperfusion process, the fact that was concluded by the reduction of the AGEs concentration in ovarian homogenates of controlled 24 hours reperfusion group.
