Laparoscopic hernia repair enhances early return of physical work capacity.
Several researchers have documented less postoperative pain and a quicker return to daily activities after laparoscopic herniorrhaphy. However, little objective data that validates this hypothesis exists. This study compares the rate of postoperative physical work capacity with return to preoperative levels, which is measured by a standard treadmill test in patients who underwent laparoscopic and conventional open hernia repair. Patients completed a 6-minute walking test preoperatively and 1 week postoperatively using a nonmotorized treadmill. The distance walked was recorded. If the distance that a patient achieved at 1 week was not within 0.02 miles of the preoperative values of the patient, the patient was asked to return at 1 month for repeat testing. Patients were enrolled prospectively in this study from October 1997 to February 1999. Sixty-six patients participated in the study (27 laparoscopic herniorrhaphies and 39 open herniorrhaphies were performed). There was no significant difference in age, body mass index, or preoperative distance achieved among the two groups. At 1 week, patients who underwent laparoscopic repair demonstrated a mean increase of 18 meters from preoperative distance (P = 0.07). In the open group, patients demonstrated a mean decrease of 90 meters at 1 week (P = 0.001). The change in distance at 1 week between the laparoscopic and the open groups was statistically significant (P = 0.001). However, at 1 month, there was no significant difference among the two groups. Measured using treadmill walking, laparoscopic hernia repair seems to offer an early advantage to open repair in return-to-physical-work capacity.
