Background:
This study was performed to determine if defect size after laparoscopic incisional hernia repair is predictive of recurrence during the long-term follow-up evaluation.
Methods:
We performed a prospective clinical study on 310 patients who underwent laparoscopic incisional hernia repair to identify predictable risk factors for hernia recurrence. Univariate and multivariate Cox regression analysis were used. The defect size was analyzed with curve receiver operating characteristic curve.
Results:
The overall recurrence rate was 6% after an average follow-up period of 60 months. On univariate analysis of the defect size (categories: <10 cm, 10-12 cm, and >15 cm), obesity, previous repairs, hernia location, surgical time, hospital stay, morbidity, and recurrences were significantly different (P < .001). By multivariate analysis, only obesity and defect size were independent prognostic factors (P < .001).
Conclusions:
The predictive value of defect size is shown. Patients with large defects have a higher risk of recurrence. Our study recommends reserving the laparoscopic technique for hernias not exceeding 10 cm in size, where it can be put to better use.
