Neonatal colon perforation due to anorectal malformations: Can it be avoided?

Table 1 Classification of intestinal perforations complicated with anorectal malformations (n = 25)

Type of perforation	Frequency1	Description	Recommended management
Type 1		Perforation occurring before relief of obstruction
Type 1a	16%	Involving cecum or proximal ascending colon	Cecostomy + distal colostomy
Type 1b	8%	Involving transverse colon including the 2 flexures	Exteriorization of perforation (as colostomy)
Type 1c	60%	Involving distal sigmoid or rectum	Closure of perforation + proximal colostomy
Type 1d	4%	Other sites such as vagina in cloaca	Closure of perforation + proximal colostomy
Type 2	12%	Perforation occurring in the postoperative period	Exteriorization of the perforation site
