Effect of RET c.2307T>G Polymorphism on the Outcomes of Posterior Sagittal Neurectomy for Hirschsprung Disease Procedure in Indonesian Population

We investigated the effect of RET c.2307T>G polymorphism on the outcomes of posterior sagittal neurectomy for Hirschsprung disease (PSNHD) procedure in Indonesia. Hirschsprung disease (HSCR) is a neurocristopathy characterized by absence of enteric ganglia along variable lengths of the intestine in neonates. The RET c.2307T>G polymorphism has been shown to be associated with HSCR. Many surgical techniques with some advantage and disadvantage were established for HSCR. We have conducted PSNHD in short-segment HSCR patients.Thirty-one nonsyndromic HSCR patients underwent PSNHD. The polymorphism was determined using PCR-RFLP in genomic DNA. The rate of enterocolitis and constipation outcomes following PSNHD were 6 (19%) and 4 (13%) patients, respectively. The RET c.2307T>G polymorphism did not influence either enterocolitis or constipation outcome following PSNHD at P value of 0.07 (OR = 0.28; 95% CI = 0.08–1.05) and 0.67 (OR = 0.58; 95% CI = 0.12–2.76), respectively. Our study suggested that RET c.2307T>G polymorphism may not affect outcomes of PSNHD procedure in Indonesia. Furthermore, a multicenter study with a larger sample size is necessary to clarify this result.
