Summary
Measuring postoperative physical activity with an accelerometer provides an objective assessment of recovery after laparoscopic surgery compared to open surgery. This method offers a quantitative parameter for evaluating patient convalescence and surgical stress.
Area of Science:
- Surgical innovation
- Minimally invasive surgery
- Patient recovery monitoring
Background:
- Traditional clinical parameters for assessing postoperative recovery are subjective.
- Objective parameters are needed to accurately evaluate the impact of surgical stress.
Purpose of the Study:
- To investigate the utility of accelerometer-measured postoperative physical activity as an objective parameter for evaluating recovery.
- To compare recovery between laparoscopic and open gastrectomy procedures.
Main Methods:
- Compared cumulative acceleration of voluntary movement using an accelerometer in 75 patients.
- Patients underwent laparoscopic partial gastrectomy (LPG), open distal gastrectomy (ODG), or open total gastrectomy (OTG).
Main Results:
- Laparoscopic partial gastrectomy (LPG) patients showed significantly better physical activity than open surgery groups (ODG, OTG).
- Recovery time, defined by 90% return of physical activity, was significantly shorter for LPG (2.8 days) versus ODG (6.6 days) and OTG (7.8 days).
Conclusions:
- Postoperative recovery varies with the degree of surgical stress.
- Accelerometer-based measurement of physical activity is a valuable objective and quantitative parameter for assessing surgical recovery.
