Background:
With the technical advances of recent years, the number of operative manipulations in the abdominal cavity by laparoscopic surgery is now considered to be the same as that using classical open surgery. The question has been raised whether laparoscopic colorectal surgery with lymphadenectomy improves the recovery compared to open surgery.
Methods:
We compared patients' physical activity for 7 days postoperatively as measured with an accelerometer between laparoscopic-assisted colorectal resection (LAC, n = 32) and classical open colorectal surgery (OC, n = 30).
Results:
Physical activity expressed as cumulative acceleration was significantly higher in the LAC than in the OC group on each postoperative day. The recovery time, defined as the day on which the cumulative acceleration recovered to 90% of the preoperative level, was significantly shorter (p < 0.05) in the LAC (3.4 +/- 1.2 days) than in the OC group (6.8 +/- 1.7 days).
Conclusion:
Our results showed that the duration of convalescence with LAC was significantly shorter than that with the OC procedure. Laparoscopic colorectal surgery appears to allow an earlier recovery after the operation than the classical open procedure, and it is less invasive as assessed by convalescence.
