Summary
Laparoscopic cholecystectomy (LC) results in a significantly lower stress response and tissue trauma compared to conventional cholecystectomy (CC). Biochemical markers like stress hormones and interleukins confirm LC as a less invasive surgical option.
Area of Science:
- Surgical Innovation
- Minimally Invasive Surgery
- Surgical Stress Response
Background:
- Surgical trauma elicits predictable hormonal and immunological responses.
- The extent of injury correlates with the magnitude of these physiological changes.
Purpose of the Study:
- To objectively compare the surgical stress and tissue trauma between laparoscopic cholecystectomy (LC) and conventional cholecystectomy (CC).
- To evaluate biochemical stress parameters, including stress hormones, blood glucose, and interleukins, as indicators of operative trauma.
Main Methods:
- A prospective study comparing biochemical stress parameters in patients undergoing elective cholecystectomy.
- Measured blood levels of epinephrine, norepinephrine, glucose, interleukin-1 beta, and interleukin-6 in 40 LC patients and 18 CC patients.
- Excluded patients with acute cholecystitis, pancreatitis, choledocholithiasis, or malignancy.
Main Results:
- Higher postoperative levels of epinephrine, norepinephrine, and glucose were observed after CC.
- Elevated interleukin-1 beta and interleukin-6 responses were noted during and after CC compared to LC.
- Norepinephrine levels remained significantly higher postoperatively in the CC group.
Conclusions:
- Laparoscopic cholecystectomy demonstrates a demonstrably lower intraoperative and postoperative stress response.
- Biochemical markers indicate reduced tissue trauma associated with LC compared to CC.
- Findings align with clinical observations of LC's favorable outcomes.
