2. Anorectal malformations refer to anomalies of the rectum and distal anus,
the urinary tract, and the genital tract.
They have an incidence of approximately 1 in 5000 live births worldwide
These malformations may range from simple imperforate anal to include
other associated complex anomalies of genitourinary (GU) and pelvic
organs,
Which may require extensive treatment for fecal, urinary, and sexual
function.
The term imperforate anus (absence of the anal opening)
3. Anorectal malformations are frequently associated with other
anomalies. Some babies have VACTERL conditions.
VACTERL refers to the presence of three or more of the following
anomalies:
Vertebral anomalies,
Anal atresia,
Congenital heart disease,
Tracheoesophageal fistula,
Renal anomalies, and
Limb defects
Boys with an imperforate anus frequently have a rectourethral
fistula and girls generally have a rectovestibular fistula.
5. Generally any congenital malformation can cause ARM
Family history unusual
Autosomal recessive when genetically linked
Incidence 1/5000 live births
6. The major part of the anus and rectum develops during 4th to 6th
weeks of IUL
The cloaca becomes the common channel for developing the urinary,
genital and rectal system
The division of cloaca occurs at 6th week forms the an anterior
urogenital sinus and posterior intestinal channel by the urorectal
septum.
Failure or any interception in the division of cloaca into the
urogenital tract and the rectum results in the high and intermediate
type of anomalies.
7. Infant with out normal anus
With a visible abnormal opening
Anal stenosis
Ano perineal fistula
Anovestibular fistula
with an invisible but manifested opening of the bowel
Rectovagianal fistuala
Recto urethral fistula
Rectovesicular fistula
No manifested opening of the bowel
Persistant anal membrane
Rectal atresia

16. No or abnormally formed anal opening
Failure to pass meconium within the first 24 hours of birth may
be indicative of imperforate anus
Fistula
Presence of mechonium in urine
Progressive abdominal distension
Vomiting
Rectal tube cannot be inserted
17. Imperforate anus
Anal stenosis
Anal agenesis
Rectal agenesis
Recto perineal fistula
Rectovaginal fistula
Cloacal malformations in girls, in which the urinary tract,
vagina, and rectum fuse together, forming a common
channel

19. Physical examination
Cystoscopy
An IV pyelogram and a voiding cystourethrogram are
performed to evaluate associated anomalies involving the
urinary tract.
Other diagnostic examinations that may be performed
include pelvic MRI, radiography, ultrasonography, and
fluoroscopic examination of pelvic anatomic contents and
lower spinal anatomy.
20. Newborn is stabilized andkept NPO for further evaluation
IV fluids are provided to maintain glucose and fluid and
electrolyte balance.
Current recommendation is that surgery be delayed at
least 24 hours to properly evaluate for the presence of a
fistula and possibly other anomalies
21. Surgical
Varies according to the defect
Low ARM
Rectal cut back anoplasty or Y-V plasty
Dialation of fistula
High ARM
Colostomy
Posterior sagittal anorectoplasty (PSARP) or other pull-
through with colostomy
22. This surgery generally occur between 3 to 6 months of
age, although timing varies among surgeons.
When the operative site has healed, approximately 2
weeks after surgery, anal dilations are begun.
When the desired size of the anal opening has been
achieved, the colostomy is closed

37. Assisting in identification of anorectal malformations
A newborn that does not pass stool within 24 hours after birth or
has meconium that appears at a location other than the anal
opening requires further assessment.
Preoperative care includes diagnostic evaluation,
GI decompression,
Bowel preparation, and
IV fluids
38. Acute pain
Impaired skin integrity
Body image disturbance
Interrupted family process
Parental anxiety
Knowledge deficit
Risk for infection
Risk fluid volume deficit
Risk for electrolyte imbalance
Risk for complications
Pre-post operative nursing diagnosis
39. General preoperative care
Postoperative nursing care after anoplasty is primarily directed
toward healing the surgical site without other complications.
A program of anal dilations is usually initiated then the child
returns for the 2-week checkup
Feedings are started soon after surgical repair, and
breastfeeding is encouraged because it causes less
constipation
40. In neonates with anomalies such as cloaca (female),
rectourethral prostatic fistula (males), and vestibular fistula
(females), a descending colostomy is performed to allow fecal
elimination and avoid fecal contamination of the distal
imperforate section and subsequent urinary tract infection in
infants with urorectal fistulas.
Postoperative nursing care is directed toward
Maintaining appropriate skin care at the stoma sites (both distal and
proximal),
Managing postoperative pain, and
Administering iv fluids and antibiotics.
Postoperative ng decompression may be required with laparotomy, and
Maintenance of appropriate drainage
41. The PSARP is a common surgical procedure for the repair of
anorectal malformations in infants approximately 1 to 2 months
after the initial colostomy
Preoperative PSARP care often involves
Irrigation of the distal stoma to prevent fecal contamination of the
operative site
Parents must be given accurate yet simple information regarding the
infant's appearance postoperatively and expectations as to their level of
involvement in the child's care
Parents are instructed in perineal and wound care or care of the
colostomy as needed
Anal dilations may be necessary for some infants
Parents should observe stooling patterns and observe for signs of anal
stricture or complications
42. Information on dietary modifications and administrationof
medications is included in counseling
Quality of life enhanced for the child and family
43. Long-term follow-up is essential for children with complex
malformations
Toilet training is delayed, and complete continence is seldom
achieved at the usual age of 2 to 3 years
Bowel habit training,
Bowel management irrigation programs,
Diet modification, and
Administration of stool softeners or fiber help children improve bowel
function and social continence
Daily bowel irrigations (if not acheived)
Support and reassurance are important during the slow
progression to normal, socially acceptable function.
44. The child’s pain is effectively managed
Incisions heal without signs of infection.
Fluid and electrolyte balance is maintained.
Adequate bowel function is demonstrated.
The parents demonstrate an understanding of ostomy
care and other treatment protocols
