Percutaneous Lung Biopsy in Immunocompromised Pediatric Patients.

PURPOSE: To determine the diagnostic yield and safety of image-guided lung biopsies in immunocompromised pediatric patients. MATERIALS AND METHODS: This was a retrospective pediatric cohort study conducted from June 2000 to April 2017. Subjects were 0-17 years of age (median, 10 years of age). There were 46 males (48%). A total of 73 consecutive image-guided lung biopsies were performed in 68 patients (weight range, 4.9-97.3 kg [median, 25.3 kg]). The indication for biopsy was to isolate an organism to tailor medical therapy. All patients were immunocompromised with an underlying history of bone marrow transplantation (n = 50), primary immunodeficiency (n = 14), and solid organ transplantation (n = 4). Patient and technical factors were analyzed for rates of complication. RESULTS: Overall diagnostic yield was 43 of 73 patients (60%). There were 14 minor (19%) and 8 major (11%) complications. Major complications included pneumothorax or hemoptysis requiring intervention (n = 6), and death (n = 2). The histological diagnosis was an infectious cause in 5 of 8 major complications (63%). There were statistically significant differences between the rates of complications with the imaging modality used (P = .02) and the use of fine needle aspiration (P = .02). CONCLUSIONS: Image-guided percutaneous lung biopsy can be helpful in isolating an organism to tailor therapy. Biopsies performed in immunosuppressed patients result in an elevated complication risk of up to 30% and demonstrate lower diagnostic yield and increased mortality, which should warrant detailed discussion with the primary team and family.

Comparative Analysis of Intra-arterial Cone-Beam Versus Conventional Computed Tomography During Hepatic Arteriography for Transarterial Chemoembolization Planning.

PURPOSE: To compare the imaging characteristics of intra-arterial cone-beam computed tomography during hepatic arteriography (CBCTHA) versus intra-arterial computed tomography during hepatic arteriography (CTHA) for intraprocedural transarterial chemoembolization (TACE) planning. MATERIALS AND METHODS: This single-institution retrospective study included 144 patients (96 men, mean age 67.9 years; 48 women, mean age 62.3 years) who underwent 181 TACE sessions between January 2015 and July 2017. Intraprocedural CBCTHA (111 procedures) or CTHA (70 procedures) was performed for TACE planning. Reformatted maximum intensity projection CBCTHA and CTHA images were reviewed by two radiologists and classified using an ordinal scoring system (for tumor identification, tumor feeder vessel identification, and streaking artifact) and a binary scoring system (for the presence of breathing motion artifact and field of view encompassing the entire liver). Data were analyzed using an F test and a z-score test. RESULTS: There were no significant differences in demographic and tumor characteristics between the CBCTHA and CTHA patient cohorts. CTHA was superior to CBCTHA for tumor identification (P < .0001), tumor feeder vessel identification (P < .05), streaking artifact (P < .0001), and field of view encompassing the entire liver (P < .0001). There was a trend toward a lower frequency of breathing motion artifact with CTHA than with CBCTHA (1.4% vs. 10%; P = .057). CONCLUSION: CTHA provides improved clinical relevant imaging information compared to CBCTHA for intraprocedural TACE planning. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Intraoperative ear bleeding with bilateral otorrhagia during laparoscopic sacrocolpopexy.

BACKGROUND: Spontaneous perioperative otorrhagia is an extremely rare entity with only 4 cases reported in the literature to date, all of which were recognized after the termination of the procedure. CASE: We describe the first reported case of otorrhagia recognized intraoperatively causing abortion of the procedure in a 60-year-old woman undergoing laparoscopic sacrocolpopexy. Otoscopy by the otolaryngology service revealed multiple intracutaneous hematomas and bleeding in bilateral external auditory canals. Computed tomography scan of the head revealed no intracranial hemorrhage. She underwent postoperative drainage by the otolaryngology service with no permanent ear-related sequelae. CONCLUSIONS: We present the fifth reported case of spontaneous perioperative otorrhagia, the first of which to be noticed intraoperatively and cause premature termination of the procedure. The etiology is postulated to be increased arterial and venous pressures causing rupture of subcutaneous capillaries. In our case, several factors may have contributed to this event, including steep Trendelenburg patient positioning, intraperitoneal carbon dioxide insufflation from laparoscopy, and an intraoperative hypertensive episode.

The fate of transitional urology patients referred to a tertiary transitional care center.

OBJECTIVE: To determine the changes in management of children with neurogenic bladder (NGB) or genitourinary congenital anomalies as they moved to our transitional care clinic at the Center for Restorative Pelvic Medicine, a multidisciplinary center led by an adult urologic team dedicated to the long-term care of these patients. MATERIALS AND METHODS: We retrospectively reviewed charts of patients with NGB or genitourinary congenital abnormalities referred between 2010 and 2013. Analysis included patient characteristics, causes of NGB, bladder management, recurrent urinary tract infection, stones, renal function, upper tract studies, video urodynamics, and change in management. RESULTS: Twenty-four patients with an average age of 22.0 ± 2.7 years were included in analysis. Management was altered in 70.8% of patients (n = 17). Surgical management was instituted in 58.3% (n = 14 of 24) of patients and included bladder augmentation or urinary diversion (n = 7), intravesical botulinum toxin A injections (n = 5), cystolitholapaxy, or cystolithotomy (n = 2). Conservative management was changed in 12.5% (n = 3) of patients and included initiating anticholinergic medication (n = 2) or self-catheterization (n = 1). Follow-up was 8.9 ± 12.1 months. CONCLUSION: There is an immense need for transitional care of patients with NGB or genitourinary congenital abnormalities as they grow into adulthood. Nearly 71% of our patients had a change in their bladder management with 38% undergoing a major surgery. This study emphasizes the necessity for a dedicated adult urologic team in conjunction with a comprehensive team to care for these complex patients because their urologic care and needs may vary significantly from their childhood.
