Background: Severe pruritus caused by progressive familial intrahepatic cholestasis (PFIC) and Alagille syndrome (AGS) is refractory to medical treatment. Surgical interruption of the enterohepatic circulation is considered the mainstay of alleviating distressing symptoms and delaying cirrhosis. Aim and Objectives: This study aims to evaluate the short-term effect of partial external biliary diversion (PEBD) on pruritus, liver disease progression, patient's growth, and quality of life. Material and Methods: This prospective cohort study enrolled children with PFIC and AGS from July 2019 to July 2021, whose guardians consented to the PEBD procedure. A standard surgical approach was performed by a single surgeon. Outcomes were measured subjectively and objectively pre- and post-procedure using the pruritus 5-D itching score, Paediatric Quality of Life Inventory scale (PedsQL), growth parameters, bile acids level, and liver function tests. Patients' follow-up period ranged from 6 to 12 months. Results: Seven patients had PEBD procedure; five with PFIC and two with AGS. A significant improvement was detected in the 5-D itching score (p-value < 0.001), PedsQL (p-value < 0.001), and bile acids level (p-value 0.013). The preexisting growth failure was ameliorated. The downward trend in the bilirubin level was not significant. No influential difference in the other liver function tests occurred. No intra-operative complications encountered. Only one case had a post-operative stoma prolapse which was managed surgically. Conclusion: PEBD procedure could be considered as an effective and safe treatment options for intractable pruritus in patients with PFIC or AGS, providing preserved synthetic liver functions.
