OBJECTIVE: It is proposed that radiofrequency thermocoagulation (RFT) under general anaesthesia without waking the patient intra-operatively, which is usually performed to confirm lesion location, will reduce the peri-operative discomfort and anxiety suffered by patients.
METHODS: A retrospective review of all procedures, identified through standard hospital audit codes and performed by a single surgeon from 2000 to 2007. Postal questionnaires were sent to all eligible patients. Outcome criteria included pain relief, adverse events and patients' views on satisfaction, timing and outcomes. A Kaplan-Meier plot was used to determine actuarial rates of pain relief.
RESULTS: Follow-up was available for 84% (37/44) of patients. Complete post-operative pain relief was 96% (42/44). The actuarial rates of complete pain relief at 6, 12, 24 and 36 months were 89%, 79%, 66% and 43%. No patients reported an outcome that did not meet their expectations while 71% (20/28) had an outcome that was better than their expectation. Serious complications included corneal numbness affecting 12% (5/41), but no cases of keratitis and a single case of anaesthesia dolorosa.
CONCLUSIONS: Not waking a patient intra-operatively when performing a RFT is a viable treatment option that results in excellent early pain relief, comparable to results in the literature and without an increase in complications. Patient reported outcomes indicate a high rate of satisfaction and are a novel addition to our understanding of the procedure; there is no comparable data in the literature documenting patient satisfaction outcomes when the procedure is performed with patient waking.
