Table 1 Comparison of outcomes of the open posterior sagittal anorectoplasty and the laparoscopic-assisted anorectal pull-through for management of anorectal malformations, subdivided into high and low malformations

	Open PSARP			LAARP
	High	Low	All	High	Low	All
Short-term outcomes
Mucosal prolapse (%)	10.7	21.2	16.4	9.8	2.9	6.2
Long-term outcomes
Defecation dysfunction (%)	33.3	41.8	40.3	36.4	27	29.2
Rectoanal inhibitory reflex positive (%)	-	-	57.4	-	-	72.7

Rates extrapolated from pooled data from a meta-analysis comparing the different techniques[26]. PSARP: Posterior sagittal anorectoplasty; LAARP: Laparoscopic-assisted anorectal pull-through.
