Özet
Study Objective: To investigate whether carbon dioxide pneumoperitoneum causes ischemia-reperfusion injury to the ovaries during laparoscopic surgery. Design: A prospective controlled clinical study (Canadian Task Force classification II-1). Setting: A tertiary academic center. Patients: Premenopausal women who underwent hysterectomy with bilateral salpingo-oophorectomy (HSO) via open abdominal and laparoscopic approaches between 2014 and 2015. Interventions: In both surgical approaches, unilateral oophorectomy was performed immediately after abdominal entry, and the remaining contralateral ovary was excised at the end of the hysterectomy in order to compare the effect of these surgical procedures on ovarian tissue. Additionally, plasma samples were collected at the following time points: (1) before abdominal entry, (2) at the end of hysterectomy, and (3) before contralateral oophorectomy. Plasma samples were assessed for biochemical oxidative stress markers malondialdehyde (MDA) and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Ovarian tissue samples were assessed for MDA and further evaluated for ischemia-reperfusion injury using a histologic scoring method. Measurements and Main Results: Twenty premenopausal women undergoing HSO via open abdominal surgery (n = 10) and laparoscopy (n = 10) were included. Baseline characteristics (age, body mass index, parity, and gravida) and operative data (operative time, estimated blood loss, and intraoperative complication) were similar between groups. Perioperative plasma MDA levels, histologic scores, and tissue oxidative stress markers did not show a significant difference in either group or between groups. However, plasma 8-OHdG levels were significantly different when the second sample in the abdominal HSO group was compared with the first sample in the abdominal HSO group and the third sample in the laparoscopic HSO group (p =.012 and .001, respectively). Conclusion: Carbon dioxide pneumoperitoneum does not cause ischemia-reperfusion injury in the human ovaries at clinically safe levels of intra-abdominal pressure. (C) 2017 AAGL. All rights reserved.
