Classification of short-term complications after transanal endorectal pullthrough for Hirschsprung's disease using the Clavien-Dindo-grading system

Purpose Hirschsprung's disease (HSCR) is a developmental defect of the enteric nervous system. Transanal endorectal pullthrough (TERPT) is one of the surgical procedures for HSCR. Clavien-Dindo is an objective classification system, used worldwide, to describe postoperative complications. The aim of this study was to use Clavien-Dindo grading for short-term complication after TERPT. Methods This was a cohort study including all 69 individuals, with biopsy-verified HSCR, managed with TERPT at our institution between 2006 and 2018. Data on the surgical procedure, as well as short-term complications, were retrieved from the medical records. The main outcome was postoperative complications graded according to Clavien-Dindo. Results Fifteen (22%) of the 69 patients (51 males) had a short-term postoperative complication graded according to Clavien-Dindo. The complications were Grade I in ten patients, Grade II in four patients, and Grade IIIb in one patient. Individuals with a Clavien-Dindo complication had a significantly longer post-operative hospital stay [median 6 days (4-30) compared to 4 days (1-22), p = 0.035]. Conclusions It is important to describe postoperative complications in a structured way to make it possible to compare studies. Post-operative complications, according to Clavien-Dindo, occurred in 22% of the patients after TERPT.
