INTRODUCTION

Laparoscopic abdominal surgery is associated with less pain and better recovery (1,2).

However, these studies did not evaluate which health functions have recovered. The purpose of this study was to analyze the impact of laparoscopic colonic surgery on postoperative functional exercise capacity.

METHODS

After approval by the local Ethics Committee patients undergoing elective colonic surgery were allocated to two groups: laparoscopy, group A, (n = 12), and laparotomy, group B, (n = 13). All patients received a standardized general anesthesia followed by patient controlled analgesia (PCA) with morphine for 48 hours. Primary outcome measure was functional exercise capacity as assessed by the 6 minute - walking test (6 MWT) before surgery and 3 weeks after hospital discharge. This test evaluates the ability of an individual to maintain a moderate level of physical mobility that reflects activities of daily living.

RESULTS

The two groups were comparable except for body mass index (BMI), which was higher in group A (27 ± 4.5 kg/m2) than in group B (23 ± 3.5 kg/m2), (p = 0.021). Duration of surgery and cumulative (48 h) consumption of PCA morphine was similar in both groups.

The 6 MWT before surgery was 521 ± 71 m in group A and 456 ± 59 m in group B (NS).

At 3 weeks after hospital discharge the 6 MWT decreased significant in both groups. In group A down to 413 ± 108 m (p = 0.007) and group B down to 349 ± 105 m (p = 0.003).

There was no difference between the two groups. Length of stay was significantly shorter in group A, 4.5 ± 2.2 days than in group B, 9.4 ± 6.2 days (p = 0.02).

DISCUSSION

These preliminary findings indicate that postoperative functional exercise capacity as assessed by the 6 MWT decreased to the same extent irrespective of surgical approach and time of hospital discharge.
