IntroductionPosttraumatic complex regional pain syndrome (CRPS) has a strongly negative impact on rehabilitation and activities of daily living. Treatment is most often unrewarding.AimTo analyze the efficacy of endoscopic thoracic sympathectomy (ETS) in reducing pain and disability associated with CRPS prospectively.Patient And MethodsOver 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.ResultsOne 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%.ConclusionETS is effective at decreasing pain and improving quality of life, and should therefore be considered in the treatment of CRPS.
