LAPAROSCOPIC VERSUS OPEN SURGICAL TECHNIQUES FOR VENTRAL OR

INCISIONAL HERNIA REPAIR

Cochrane Database of Systematic Reviews, Issue 04, 2011 - DOI:

10.1002/14651858.CD007781.pub3

Main results

We included 10 RCTs with a total number of 880 patients suffering primarily from primary

ventral or incisional hernia. The recurrence rate was not different between

laparoscopic and open surgery (RR 1.22; 95% CI 0.62 to 2.38; I2 = 0%), but patients

were followed up for less than two years in half of the trials. Results on operative

time were too heterogeneous to be pooled. The risk of intraoperative enterotomy was

slightly higher in laparoscopic hernia repair (Peto OR 2.33; 95% CI 0.53 to 10.35), but

this result stems from only 7 cases with bowel lesion (5 vs. 2). The most clear and consistent

result was that laparoscopic surgery reduced the risk of wound infection (RR = 0.26;

95% CI 0.15 to 0.46; I2= 0%). Laparoscopic surgery shortened hospital stay

significantly in 6 out of 9 trials, but again data were heterogeneous. Based on a small

number of trials, it was not possible to detect any difference in pain intensity, both

in the short- and long-term evaluation. Laparoscopic repair apparently led to

much higher in-hospital costs.

Authors' conclusions

The short-term results of laparoscopic repair in ventral hernia are promising. In

spite of the risks of adhesiolysis, the technique is safe. Nevertheless, long-term

follow-up is needed in order to elucidate whether laparoscopic repair of ventral/incisional

hernia is efficacious.

"The final word on hernia will probably never be written. In collecting, assimilating and distilling the wisdom of today we must provide a base from which further advances may be made."
