ABSTRACT
PURPOSE: To retrospectively evaluate the safety and efficacy of transrectal ultrasound (TRUS) probe use for aspiration and drainage of pelvic abscesses in children. MATERIALS AND METHODS: Patient demographics, procedural details, technical success, safety, and clinical course of TRUS procedures were retrospectively analyzed. Between 2007 and 2016, 118 TRUS-guided procedures were performed in 115 children (60 males, 55 females); median age was 12.4 years (range, 2.4-17.9 years) and median weight was 45 kg (range, 12.6-112 kg). Ten children were 5 years of age or younger. RESULTS: In total, 113/118 procedures were performed under general anesthesia. The rectum accommodated the probe and needle guide without resistance in all children (technical feasibility, 100%). Abscesses were anterior to the rectum in 116/118 and posterior in 2/118. One hundred twelve collections were drained, 4 were aspirated, and 2 procedures were aborted, both subsequently successfully drained (2 and 3 days later). One patient underwent repeat drainage after 28 months. No major complications were reported. Median times to temperature normalization was 0 days (mean, 1.2; range, 0-13 days), catheter dwell time 5 days (mean, 6; range, 2-21 days), drain removal to discharge 1 day (mean, 2; range, 0-41 days), and follow-up 117 days (mean, 195; range, 5-2,690 days). CONCLUSIONS: TRUS-guided drainage using the TRUS probe and needle guide is a safe and effective method for aspiration and drainage of pelvic abscesses in children as young as 2 years.

PURPOSE: To evaluate image-guided bone biopsy for bone histomorphometry to assess osteoporosis in children with respect to safety and yield. MATERIALS AND METHODS: A single-center retrospective review was performed of 79 bone biopsies in 73 patients performed between 2007 and 2015. Biopsies of the iliac bone were performed under general anesthesia, after tetracycline labeling, using a Rochester needle (Medical Innovations International, Inc, Rochester, Minnesota). Ultrasound and fluoroscopic guidance were used in all procedures. Biopsy technique, technical success, safety, and histomorphometry results (complete, incomplete, none) were analyzed. RESULTS: There were 41 male patients (51.8%). Technical success was achieved in 76/79 (96%) procedures. Of 79 biopsies, 75 (95%) were uneventful. Unplanned overnight observation was required in 3 (minor SIR grade B), and prolonged hospital stay owing to hematoma causing nerve compression pain was required in 1 (major SIR grade D). Complete histomorphometric reports were obtained in 69 (87%) procedures, incomplete reports were obtained in 7 (9%), and no reports were obtained in 3(4%). Incomplete reports were insufficient to provide a definitive diagnosis or guide treatment. Histomorphometry impacted subsequent therapy in 69 (87%) biopsies. CONCLUSIONS: Image-guided bone biopsy for osteoporosis using the Rochester needle is a valuable and safe technique for establishing the diagnosis of osteoporosis and directing treatment based on histomorphometry results.
