Congenital duodenal obstruction repair with and without transanastomotic tube feeding: a systematic review and meta-analysis

ObjectiveTo determine the impact of transanastomotic tube (TAT) feeding in congenital duodenal obstruction (CDO).DesignSystematic review with meta-analysis.PatientsInfants with CDO requiring surgical repair.InterventionsTAT feeding following CDO repair versus no TAT feeding.Main outcome measuresThe main outcome was time to full enteral feeds. Additional outcomes included use of parenteral nutrition (PN), cost and complications from either TAT or central venous catheter. Meta-analyses were undertaken using random-effects models (mean difference (MD) and risk difference (RD)), and risk of bias was assessed using the Risk Of Bias In Non-randomised Studies - of Interventions (ROBINS-I) tool.ResultsTwelve out of 373 articles screened met the inclusion criteria. All studies were observational and two were prospective. Nine studies, containing 469 infants, were available for meta-analysis; however, four were excluded due to serious or critical risk of bias. TAT feeding was associated with reduced time to full enteral feeds (-3.34; 95% CI -4.48 to -2.20 days), reduced duration of PN (-6.32; 95% CI -7.93 to -4.71 days) and reduction in nutrition cost of 867.36 pound (95% CI 304.72 pound to 1430.00) pound. Other outcomes were similar between those with and without a TAT including inpatient length of stay (MD -0.97 (-5.03 to 3.09) days), mortality (RD -0.01 (-0.04 to 0.01)) and requirement for repeat surgery (RD 0.01 (-0.03 to 0.05)).ConclusionTAT feeding following CDO repair appears beneficial, without increased risk of adverse events; however, certainty of available evidence is low. Earlier enteral feeding and reduced PN use are known to decrease central venous catheter-associated risks while significantly reducing cost of care.PROSPERO registration numberCRD42022328381.
