Overview of complications associated with epidermolysis bullosa: A multicenter retrospective clinical analysis of 152 cases

Background/Purpose Epidermolysis bullosa (EB) is a rare disease of skin and mucosa which may causes surgical complications. We review these in a large patient cohort from Saudi Arabia. Methods A retrospective study was conducted at 21 centers between 2003 and 2020. Demographic data and information on EB type [Simplex (EBA), Dystrophic (DEB) and Junctional (JEB)]. The dataset included clinical features, operations, surgical complications, and treatment. Results There were 152 (63 male) children with EB [EBS n = 93 (61.2%); DEB n = 30 (19.7%); JEB n = 25 (16.4%), and Kindler syndrome n = 4, (2.6%)]. Children with JEB and DEB tended to have a higher frequency of skin and musculoskeletal system complications (skin cancer, pseudosyndactyly and recurrent skin infection). Esophageal strictures were mostly seen in DEB (n = 19, 63%) and to a lesser extent in EBS (n = 20, 21%) and JEB (n = 4, 16%). Pyloric atresia was uncommon (n = 4) and limited to those with JEB. Percutaneous gastrostomy for feeding support was used in all types. Ankyloglossia was common but often recurred (76%) after division. Circumcision was usually safe and complication-free in male children except in those with severe JEB. Phimosis was reported in 10% of uncircumcised patients. Conclusions Our series showed that surgeons play a key role in the management of some complications associated with EB. It is also important to be aware of the particular sub-type as this can predict the natural history and likely response to treatment. Level of Evidence 2
