Surgical stress response: does endoscopic surgery confer an advantage?

Area of Science:

• Minimally Invasive Surgery
• Surgical Physiology
• Postoperative Recovery

Background:

• Open surgery causes significant endocrine-metabolic and immune system changes, impaired lung function, and hypoxemia, contributing to postoperative morbidity.
• Endoscopic surgery, particularly laparoscopy, has been investigated for its effects on these physiological responses.

Purpose of the Study:

• To compare the physiological effects of endoscopic surgery versus open surgery.
• To evaluate the impact on endocrine-metabolic responses, immune function, pulmonary function, and hypoxemia.

Main Methods:

• Comparative analysis of physiological data between patients undergoing open and endoscopic surgical procedures.
• Review of existing literature comparing laparoscopic and open surgery outcomes.

Main Results:

• Endoscopic surgery has minimal impact on endocrine-metabolic responses.
• Slight, inconsistent reductions in inflammatory and immune responses observed with endoscopic surgery.
• Endoscopic surgery demonstrates improved postoperative pulmonary function and reduced hypoxemia compared to open procedures.

Conclusions:

• Endoscopic surgery does not significantly alter endocrine-metabolic responses but offers improved pulmonary function and reduced hypoxemia.
• The clinical significance of these findings and the overall impact on surgical outcomes require further investigation.
• Pain management, stress reduction, and rehabilitation programs may be more critical for improving surgical outcomes than the choice of endoscopic versus open surgery.
