Anorectal Malformation

Anorectal Malformation Surgery in Children Petaling Jaya, Malaysia

Anorectal malformation is a congenital condition affecting how the anus and lower bowel develop before birth. In some children, the anus may be absent, too narrow or located in an unusual position. Anorectal malformation surgery may be needed to create or correct the passage for stool. The type and timing of treatment depend on the specific type of malformation, the child’s anatomy and overall condition. At Dr Nada’s paediatric surgical practice in Malaysia, children with anorectal malformations can be assessed to determine suitable treatment and surgical care.

What Is Anorectal Malformation?

Anorectal malformation is a condition present from birth that affects the anus and rectum. The rectum is the lower part of the large intestine that stores stool before it leaves the body. The condition can vary significantly between children. In some cases, the anus does not open normally. In others, the rectum may connect to another part of the urinary or reproductive system through an abnormal passage called a fistula. Because anorectal malformations have different forms, treatment needs to be planned according to each child’s anatomy.

Anorectal Malformation in Children

Signs of anorectal malformation in children are usually noticed soon after birth. A newborn may have an abnormal-looking or absent anal opening, difficulty passing stool or abdominal swelling. Some babies may pass stool through an unusual opening rather than through the normal anus. These signs require assessment by an appropriate medical team. Not every newborn with difficulty passing stool has an anorectal malformation, as other conditions can also affect bowel movements.

How Is Anorectal Malformation Diagnosed

The doctor will examine the baby or child and assess the position and appearance of the anal opening. Further investigations may be needed to understand the anatomy and identify any associated conditions. These may include imaging tests such as ultrasound, X-rays or other specialised studies. Children with anorectal malformations may also have abnormalities involving the urinary system, kidneys, spine or other organs. The medical team may therefore recommend additional investigations depending on the individual child.

Anorectal Malformation Treatment

Treatment depends on the type and severity of the malformation and the child’s overall condition. Some children may require temporary measures to allow stool to pass safely before definitive surgery. In certain cases, a stoma may be created. A stoma is an opening made through the abdominal wall that allows stool to leave the body into a special bag. The treatment plan is carefully considered based on the child’s anatomy, associated conditions and clinical findings.

Anorectal Malformation Surgery

Anorectal malformation surgery aims to create or reposition the anal opening and establish an appropriate pathway for stool to pass. One commonly used operation for suitable children is a posterior sagittal anorectoplasty, also known as PSARP. During this procedure, the surgeon separates abnormal connections where necessary and positions the rectum within the muscles that help control bowel movements.The exact procedure depends on the type of anorectal malformation.

ARM Surgery

ARM surgery refers to surgical treatment for anorectal malformations. The approach can differ between children because anorectal malformations have several different forms. Some children may require more than one stage of treatment. The surgical plan may include temporary bowel diversion followed by definitive repair and, where appropriate, later stoma closure. Parents will be advised about the planned procedure based on their child’s individual condition.

Imperforate Anus Surgery

An imperforate anus is one type of anorectal malformation where the normal anal opening is absent or does not develop in the usual position. Imperforate anus surgery is planned according to the anatomy and type of malformation. Some children may have an abnormal connection between the rectum and the urinary or reproductive tract, which also needs to be considered during treatment.

Care After Surgery

After anorectal malformation surgery, the child will require follow-up to monitor bowel function and overall development. Bowel movements can vary after treatment, and some children may need ongoing bowel management. The type of follow-up depends on the child’s condition, the type of malformation and the surgery performed.Parents will receive individual advice about feeding, bowel care, wound care and follow-up.

Laparoscopic Surgery for Anorectal Malformation

Laparoscopic or keyhole surgery may be considered in selected children as part of the treatment of certain anorectal malformations. This approach uses small incisions and a camera to allow the surgeon to work inside the abdomen. Whether laparoscopic surgery is appropriate depends on the child’s anatomy, age, condition and surgical requirements.

Paediatric Surgical Care for Anorectal Malformation

Anorectal malformations require individual assessment because the anatomy and treatment needs can differ significantly between children. Dr Nada provides paediatric surgical assessment and care for children with congenital surgical conditions. Treatment decisions are based on the child’s examination, investigations, anatomy and overall health.Parents can discuss their child’s diagnosis, anorectal malformation surgery and possible treatment options with the paediatric surgical team.
