Background: HSD is a developmental disorder of the intrinsic nervious system of the distal colon. Thernmanagement is pull through procedure and majority of patients do well after surgery; but 32% of patientsrncontinue to have complaints after surgery & up to 8.6% of patients can require repeat pull through. rnObjective: To describe indications for reoperation, surgical technique adopted, complications, andrnoutcome of patients who underwent a redo pull-through procedure in Tikur Anbessa hospital, Ethiopiarnfrom rnMethodology: Retrospective descriptive study design was used and the sampling procedure was a multistagernsampling.rnDescriptivernstatisticsrn(mean,rnSD,rnfrequency,rnpercentage,rngraphrnandrntable)rnwasrngeneratedrnrnbyrnusingrnSPSSrnversionrn21.rnrnResults: In our study a total of 18(4.87% of all PT) patients underwent redo pull through from 2010-rn2019. 13 (72.2%) were males & 5 (27.8%) were females with male to female ratio of 2.6:1. Soave pullrnthrough was the most frequent type of pull through on first time; done on 16(94.2%) of patients, twornbeing primary TERPT, and Duhamel pull through for one(5.9%) patient. The type of initial PT wasnâ€™trnknown in one. The indication for redo PT was pathologically confirmed persistent/aquired aganglionosisrnin 8(50%) patients. 5(27.8%) patients had anastomotic site stricture confirmed with examination underrnanesthesia. Three of them were done for persistent obstructive features with clinical impression ofrnaganglionosis. Twisted colon & anastomotic failure with colonic retraction accounted for one patientrneach. Swenson procedure was performed on 15 (83.3%)patients & Soave pull through was done onrn3(16.7%) patients as the procedure for the redo PT. Long term outcome of patients after redo pull throughrnwas measured using Holschneiderâ€™s FII score. Of the patients FII score was obtained (11 of them), 6rnpatients achieved good continence,3 has fair continence sttus & one patient was incontinent & requiredrnbowel management program to stay clean. One patient was less than 4 years old & not toilet trained yet.rnIn 7 patients the Hilschneider FII score couldnâ€™t be obtained. rnConclusion : The indication for redo pull through was persistent obstructive features in 77.8% ofrnpatients. The causes of persistent obstructive symptoms after an initial pull-through procedure are pullrnthrough of aganglionated segment (50%) and anastomotic site stricture (27.8%). 81.8% of those for whomrnthe Holschneider FII score was obtained has fair t good continence.
