Introduction: The confirmation of distal bowel patency, prior to reanastomosis in neonates, is a critical pre-operative consideration. Distal contrast study (DCS) are often performed prior to surgery to identify strictures. Chyme refeeding via the distal stoma is also often performed in these patients. We aimed to assess the role of DCS in a cohort of neonates who underwent successful chyme refeeding, and determine whether the contrast study changed management. Methods: Retrospective review of all neonates who underwent distal chyme refeeding at our institution, from 2017 to 2022. Clinical, radiological and surgical outcomes were analysed. Results: 15 neonates underwent a period of successful distal chyme refeeding, prior to stoma reversal during the study period. Chyme refeeding was predominantly performed via a feeding catheter placed into the distal stoma, at least once daily. Total number of refeeding days ranged from 9 – 54 days. 10 neonates (67%) had a DCS prior to reanastomosis. Three studies were performed prior to initiating refeeding, and seven were performed during the period of refeeding. Two neonates, with prior NEC, had a DCS suggesting possible distal bowel luminal stenosis, however in both cases, the bowel was demonstrated to be fully patent intra-operatively at the time of reanastomosis. Five children (33%) did not have a DCS prior to reanastomosis, and no adverse outcomes were observed. Conclusion: Our findings suggest that for neonates who achieve a period of successful distal refeeding prior to reanastomosis, a DCS does not appear to add further clinical information, and hence may not be routinely required.
