!!!NEW!!! CLINICAL FORUM !!!NEW!!!
to make the quarterly livelier and more beneficial for doctors and scientists !!!

On June the 1st, 2021 VSJ launches a new discussion platform in the journal.

We invite all MIS surgeons to rapidly submit for publication:
- small forms describing unusual clinical situations related to their practice,
- short clinical comments relating to any publications in VSJ, including the clinical situations described above
- brief communications of original studies deserving fast publication
- your personal opinions as part of a larger discussion on the VSJ publication
- letters concerning the topics described above

Clinical Forum gives you a means of rapid presentation of your findings in the medical databases, scientific citations on the international forum, and also an Impact Factor!

Introduction: The surgical stress response after laparoscopy is smaller when compared with open surgery, and it is expected that after minimally invasive surgery the possible development of oxidative stress will be less severe.

Aim: To evaluate markers of pro-oxidant activity – levels of lipid peroxides and malondialdehyde – and activity of the antioxidant enzymes superoxide dismutase and glutathione peroxidase in the perioperative period in patients undergoing gynecological laparoscopy and to determine whether the duration of laparoscopy can affect these changes.

Material and methods: The study included 64 patients, divided into two groups: group 1 with duration of laparoscopy up to 20 min, and group 2 with duration of the operation over 40 min. Blood samples were collected before anesthesia, 5 min after release of pneumoperitoneum, and 10 h after surgery.

Results: A statistically significant increase in the levels of lipid peroxides and malondialdehyde in samples collected after surgery was found in comparison with values obtained before surgery. Also statistically significant differences existed between groups of patients with different duration of surgery. Superoxide dismutase and glutathione peroxidase activity values were significantly decreased. They were also significantly different between the two groups with different duration of surgery.

Conclusions: In our study, levels of the markers of pro-oxidant activity increased and levels of the markers of antioxidant enzymes decreased, suggesting development of oxidative stress. The duration of laparoscopic procedures affects the severity of the presented changes.
