Randomized clinical trial comparing endovenous laser ablation, radiofrequency ablation, foam sclerotherapy, and surgical stripping for great saphenous varicose veins with 3-year follow-up.

Introduction: This study compares the outcome 3 years after treatment of varicose veins by endovenous laser ablation (EVLA), radiofrequency ablation, ultrasound-guided foam sclerotherapy (UGFS), or surgery by assessing recurrence, Venous Clinical Severity Score (VCSS), and quality of life (QOL).

Methods: A total of 500 patients (580 legs) were randomized to one of the three endovenous treatments or high ligation and stripping of the great saphenous vein (GSV). Follow-up included clinical and duplex ultrasound examinations and VCSS and QOL questionnaires.

Smoking is a risk factor for recurrence of groin hernia.

Studies of connective tissue from patients with inguinal hernia have shown that smoking may be associated with hernia formation due to a defective connective tissue metabolism. Whether smoking is a risk factor for recurrence, too, was examined in this study. From December 1990 through December 1995, 649 patients underwent hernia repair as open sutured repair (Cooper ligament or abdominal ring repair) or as open mesh repair.
