OBJECTIVE: Establish whether there are differences regarding demographics, treatment and outcomes between the groups EDLP and ELDL. METHODS: Retrospective observational study of 76 patients with EDLP surgically treated. Demographic data and outcomes of Group 1 (EDLP, 53 patients) and Group 2 (ELDL, 23 patients) were analyzed separately. RESULTS: Group 1: 51% female; 49% male. Mean age, 56.8 years. Pre-surgical development, 34 months. Group 2: 78% female; 22% male. Mean age, 63.4 years. Pre-surgical development, 10 months. Both groups were operated with the same technique and by the same surgical team. In Group 1, postoperative satisfaction was higher when the pre-surgical development was less than 18 months. In Group 2 there where no significant findings. CONCLUSION: In stenosis secondary to ELDL, age and gender distribution were very different from that found in EDLP. Early surgery led to a higher percentage of satisfaction.
