Balloon Dilatation for Corrosive Esophageal Strictures in Children: Radiologic and Clinical Outcomes

Objective: We retrospectively evaluated the effectiveness of the esophageal balloon dilatation (EBD) in children with a corrosive esophageal stricture. Materials and Methods: The study subjects included 14 patients (M:F = 8:6, age range: 17-85 months) who underwent an EBD due to a corrosive esophageal stricture. The causative agents for the condition were glacial acetic acid (n = 9) and lye (n = 5). Results: A total of 52 EBD sessions were performed in 14 patients (range 1-8 sessions). During the mean 15-month follow-up period (range 1-79 months), 12 patients (86%) underwent additional EBD due to recurrent esophageal stricture. Dysphagia improved after each EBD session and oral feeding was possible between EBD sessions. Long-term success (defined as dysphagia relief for at least 12 months after the last EBD) was achieved in two patients (14%). Temporary success of EBD (defined as dysphagia relief for at least one month after the EBD session) was achieved in 17 out of 52 sessions (33%). A submucosal tear of the esophagus was observed in two (4%) sessions of EBD. Conclusion: Only a limited number of children with corrosive esophageal strictures were considered cured by EBD. However, the outcome of repeated EBD was sufficient to allow the children to eat per os prior to surgical management.Doo EY, 2009, CLIN RADIOL, V64, P265, DOI 10.1016/j.crad.2008.10.001PARK JY, 2009, KOREAN J PEDIAT, V52, P446Hyoung J, 2008, J VASC INTERV RADIOL, V19, P736, DOI 10.1016/j.jvir.2008.01.015Ko HK, 2006, J VASC INTERV RADIOL, V17, P1327, DOI 10.1097/01.RVI.0000232686.29864.0AWeintraub JL, 2006, J VASC INTERV RADIOL, V17, P831, DOI 10.1097/01.RVI.0000217964.55623.19Wilkinson AG, 2004, PEDIATR RADIOL, V34, P414, DOI 10.1007/s00247-004-1164-1Huang YC, 2004, PEDIATR SURG INT, V20, P207, DOI 10.1007/s00383-004-1153-3Lan LCL, 2003, J PEDIATR SURG, V38, P1712, DOI 10.1016/S0022-3468(03)00638-9Fasulakis S, 2003, PEDIATR RADIOL, V33, P682, DOI 10.1007/s00247-003-1011-9Hamza AF, 2003, J PEDIATR SURG, V38, P828Kukkady A, 2002, PEDIATR SURG INT, V18, P486, DOI 10.1007/s00383-002-0798-zYEMING W, 2002, J PEDIATR SURG, V37, P398Jayakrishnan VK, 2001, PEDIATR RADIOL, V31, P98Lisy J, 1998, ACAD RADIOL, V5, P832Yararbai O, 1998, HEPATO-GASTROENTEROL, V45, P59KIM IO, 1993, RADIOLOGY, V189, P741HAN HY, 1993, J KOREAN RADIOL SOC, V29, P1181SONG HY, 1992, RADIOLOGY, V184, P373GUNDOGDU HZ, 1992, J PEDIATR SURG, V27, P767LOVEJOY FH, 1990, NEW ENGL J MED, V323, P668MAYNAR M, 1988, RADIOLOGY, V167, P703DELANGE EE, 1988, RADIOLOGY, V167, P45SATO Y, 1988, AM J ROENTGENOL, V150, P639MCLEAN GK, 1987, RADIOLOGY, V165, P35GOLDTHORN JF, 1984, RADIOLOGY, V153, P655LONDON RL, 1981, GASTROENTEROLOGY, V80, P173MUHLETALER CA, 1980, AM J ROENTGENOL, V134, P1137RAGHEB MI, 1976, SURGERY, V79, P494

Modern imaging of renal tuberculosis in children

Renal tuberculosis is relatively uncommon in children. Imaging of renal tuberculosis in children differs from adults in that intravenous urography is rarely performed for urinary symptoms in childhood because of radiation dose considerations. Modern imaging modalities include cross-sectional techniques such as ultrasound, CT and MRI, which successfully show renal, calyceal, ureteric and bladder pathology of renal tuberculosis in children.Australas Radio

Portosystemic shunt as a bridge to liver transplantation in infants: A comparison of two techniques

Portosystemic shunts can serve as a bridge to liver transplantation in patients with end-stage liver disease by providing portal decompression to treat life-threatening variceal bleeding and prevent recurrent episodes until an organ becomes available. The conventional TIPS procedure, however, is technically challenging to perform in infants due to the small size of their intrahepatic vasculature. We report two cases of emergent creation of portosystemic shunts as a bridge to liver transplantation in infants with life-threatening variceal bleeding using a conventional TIPS technique in the first case and a percutaneous DIPS technique in the other. Both procedures were successful at reducing the portosystemic pressure gradient and preventing further variceal bleeds until a liver transplant could be performed. The novel percutaneous DIPS procedure is a valuable alternative to the conventional TIPS in infants, as it is better suited for small or challenging intrahepatic vascular anatomy

Polyflex™ stenting of tracheomalacia after surgery for congenital tracheal stenosis

Polyflex™ self-expanding stents (Rüsch, Germany) were used in three young children who had presented with life-threatening long-segment tracheal stenosis with bronchial stenosis in two cases. Two children had slide tracheoplasties and subsequently aortic homografts and another tracheal resection and autotracheoplasty. However, in all cases persistent lower tracheal malacia necessitated stenting. Complications of granuloma, stent migration or dislodgement occurred in all cases. A fatal tracheo-aortic fistula occurred in one child. Granuloma in one was treated successfully with steroids. One child survives.5 page(s
