6. Needle-free electronically-controlled jet injector treatment with bleomycin and lidocaine is effective and welltolerated in patients with recalcitrant keloids. 156 Patient satisfaction All patients completed the patient satisfaction questionnaire. All patients recommended the EPI-assisted treatment with the combination of bleomycin and lidocaine to others, and preferred EPI treatment over treatment with hypodermic needles (Table S5). Less pain during treatment was the most frequently mentioned reason for this preference (87%, 13/15). Other reasons for EPI preference included better clinical results (67%, 10/15) and shorter treatment visits (33%, 5/15). Fourteen out of 15 patients (93%) were “satisfied” or “very satisfied” with the EPI-assisted treatments, while one patient rated her/his treatment satisfaction as “neutral” (7%). Eleven out of 15 patients (73%) stated that itching was reduced after treatment, and 12 out of 15 patients (80%) reported that the pain of the keloid was reduced after treatment. Postinjection hyperpigmentation was reported by three patients (20%), which was cosmetically disturbing in two patients (13%). One patient (7%) expressed discomfort due to the noise produced by the EPI device during injection.
