Abstract

INTRODUCTION: Posttraumatic complex regional pain syndrome (CRPS) has a strongly negative impact on rehabilitation and activities of daily living. Treatment is most often unrewarding.

AIM: To analyze the efficacy of endoscopic thoracic sympathectomy (ETS) in reducing pain and disability associated with CRPS prospectively.

PATIENT AND METHODS: Over a 5-year period, 12 patients (7 females and 5 males; median age 46.5 [range 34-60 years]) with posttraumatic CRPS underwent unilateral ETS. The median duration of CRPS symptoms before ETS was 3.8 months (range 1.2-19.9). The sympathetic chain was resected from the 2nd to the 5th rib, and the nerve of Kuntz was severed. Median postoperative 16 months (range 12-40). Pain was assessed, at rest (passive) and during movement (active), using a visual analogue scale (VAS) from 0 to 10.

RESULTS: One patient (8%) suffered a hydrothorax and 3 patients (25%) complained of contralateral compensatory hyperhydrosis. At 1 month (n = 12), 2 months (n = 7), 6 months (n = 12), and 1 year (n = 12) after ETS, there was a significant decrease in passive and active VAS (P < 0.05). Ten out of the 12 patients (83%) needed fewer analgesics after surgery, and eight (67%) did not need analgesics at all. The median sleep duration improved significantly from a preoperative value of 2 h (range 1-7) to a postoperative value of 6.25 h (range 3.5-8) (P < 0.001). Overall, patient satisfaction was 83%.

CONCLUSION: ETS is effective at decreasing pain and improving quality of life, and should therefore be considered in the treatment of CRPS.
