The purpose of this study was to specify the indications, applicability and final outcome of the redo definitive operations of Hirschsprung's disease. Between 1976-1993, 213 patients had undergone definitive operations of Hirschsprung's disease, In this series, 5 who required a redo pull-through operation were investigated. The redo pull-through operations were performed in 5 patients because of severe anastomotic stricture or total closure of the anastomotic site, recto-urethral fistula, anastomotic stricture, and enterocolitis due to anastomotic disruption. The initial definitive procedures were in 4 patients the Swenson operation and in one patient the Boley operation. As redo pull-through operations, the following were performed with success: in 3 patients, the Duhamel operation; and in 2 patients, the Swenson operation, The final outcome of the redo pull-through alterations were satisfactory and it can be suggested that one should not hesitate to perform a redo pull-through operation in selected Hirschsprung patients.
