In brief
This systematic review and meta-analysis of 18 studies compares transanal endorectal pull-through (TEPT) versus transabdominal approaches for Hirschsprung's disease. TEPT demonstrates superior outcomes with lower rates of postoperative constipation and enterocolitis, while incontinence rates remain comparable between techniques.

Abstract
Aim
Hesitations concerning the long-term results of transanal endorectal pull-through (TEPT) due to prolonged anal stretching and resultant stricture and continence problems has been started to be questioned. This meta-analysis intended to compare long-term results between TEPT and transabdominal (TAB) pull-through techniques in the surgical management of Hirschsprung’s disease.
Methods
All publications between the years 1998–2021 in the PubMed, Medline, Google Scholar, Cochrane databases were reviewed. Retrospective and prospective comparative studies for TEPT, TAB as well as Laparoscopic-assisted TEPT (LTEPT) were included. Data included age at operation, postoperative constipation, enterocolitis, incontinence, stricture, and soiling rates.
Results
Eighteen publications met the inclusion criteria for TAB and TEPT, and six for TEPT and LTEPT. Patients who underwent TEPT had significantly younger operation age than patients with TAB (SMD − 1.02, 95%Cl − 1.85 to − 0.18, p: 0.0168). Postoperative constipation (OR 0.39, 95% Cl 0.25–0.61 p < 0.0001) and enterocolitis (OR 0.65, 95% Cl 0.46–0.90, p: 0.0108) rates were significantly lower in TEPT groups. Postoperative incontinence (OR 1.06, 95% Cl 0.56–2.01, p: 0.8468), stricture (OR 1.97, 95% Cl 0.81–4.80, p: 0.1352) and soiling rates were similar between the two groups. Furthermore, when TEPT and LTEPT results were compared, incidence of incontinence (OR 7.01, 95% Cl 0.75–65.33, p: 0.0871), constipation (OR 1.95, 95% Cl 0.70–5.37, p: 0.199), enterocolitis (OR 3.16, 95% Cl 0.34–29.55 p: 0.3137), stricture (OR 1.33, 95% Cl 0.29–6.15, p: 0.7188) and soiling (OR 1.57, 95% Cl 0.57–4.31, p: 0.3778) were similar for both techniques.
Discussion
TEPT is superior to TAB in terms of constipation and enterocolitis. Contrary to concerns, postoperative incontinence rates are not statistically different. However, further publications about long-term LTEPT results are necessary for more reliable conclusions.
