Percutaneous discectomy is a minimally invasive procedure used to treat disc bulging, disc protrusions, or contained disc herniations that cause pressure on a nerve root or “sciatica.” It is used to treat radiculopathy that fails to improve with epidural steroid injections, and it is an alternative for some patients who are not good candidates for surgery, but have symptomatic disc disease. It is performed on an outpatient basis, although patients must rest for several days following the procedure. Some patients are able to return to full activity within a few days.
All 17 patients underwent 41 balloon dilation procedures, with each patient undergoing one to seven procedures (mean, procedures). The technical success rate was 100%, and clinical success was achieved in % (11/17) of the patients. Five patients (%) showed no recurrence of dysphagia after one session of balloon dilation. Of 12 patients (%) with recurrence of dysphagia, 10 underwent repeat balloon dilation and two underwent gastrostomy after the first session of balloon dilation. The maximum balloon diameters were 15 mm (n = 22), 20 mm (n = 16), and 25 mm (n = 3). As minor complications, three cases of type 1 esophageal rupture occurred in two patients (%). There were no major complications.
