Outcomes following endorectal pull-through for Hirschsprung disease: a retrospective study

Abstract

To share our experience in the surgical management of patients with Hirschsprung disease (HD) using the trans-anal endorectal pull-through “Soave” technique. The study included cases diagnosed as HD who were operated during the period 2008 through 2018. Cases of total colonic aganglionosis were excluded to be discussed in a separate report. The study included 67 consecutive cases of HD. All included cases underwent trans-anal endorectal pull-through which was purely trans-anal in 31 (46%), while abdominal-assisted trans-anal endorectal pull-through was applied in the remaining (54%). Early postoperative complications included 2 cases of partial dehiscence at the colo-anal anastomosis; 1 of them deteriorated after re-exploration and unfortunately died. Twenty-six cases were available to assess functional outcomes after corrective surgery. Their age at follow-up ranged between 44 months and 17 years (mean = 78.8 months; median = 72 months). All cases achieved voluntary defecation. However, fecal soiling was a common finding after surgery for HD (69%). Constipation was another common postoperative finding (73%). Lastly, a history of attacks of postoperative enterocolitis was prevalent in 19 cases (73%), which ranged between 1 and 7 attacks usually in the first 2 years after the operation. The trans-anal endorectal pull-through provides an effective surgical treatment for Hirschsprung disease. The high prevalence of fecal soiling after surgery highlights the importance of long-term follow-up to provide the required support for these patients during adolescence and transition into adulthood.
