Predictors of Postoperative Complications Following Postnatal Meningomyelocele Repair: A Retrospective Cohort Study from Northeast India
This retrospective cohort study of 104 patients in Northeast India identifies ruptured sac and defect size greater than 5 cm as independent predictors of frequent postoperative complications, such as wound issues and CSF leaks, following meningomyelocele repair.

Every human life begins with a delicate process where a long, thin tube of tissue folds and closes to form the brain and spinal cord. When this tube fails to seal completely in the very early weeks of pregnancy, a serious condition called meningomyelocele can occur. In this situation, the protective layers of the spinal cord do not close, leaving the nerves exposed through a gap in the backbone. This opening is often covered by a thin, fragile sac that may sit on the baby's back. If this sac is not repaired, the exposed nerves are at high risk of infection and damage. While doctors in some parts of the world can fix this problem before the baby is even born, many families in developing regions must wait until after birth for surgery. The goal of this later operation is to cover the nerves, seal the opening, and protect the child from infection, but the road to recovery is often difficult.
A team of researchers at Gauhati Medical College and Hospital in Northeast India set out to understand exactly what happens to children after they undergo this repair. They looked back at the medical records of 104 children, ranging from newborns to teenagers, who had their surgery between 2016 and 2025. The doctors wanted to see how often things went wrong after the operation and, more importantly, to find out which specific factors made those problems more likely to happen. By studying these real-world cases, the team hoped to identify the warning signs that could help surgeons prepare better and keep more children safe.
The study revealed that complications after the surgery were very common. Out of the 104 children, more than a third experienced problems with their surgical wounds. In some cases, the skin simply pulled apart, a condition known as wound dehiscence, while in others, the tissue died and broke down, called wound necrosis. Another frequent issue was a leak of the clear fluid that surrounds the brain and spinal cord, which occurred in nearly one in six children. Because of these leaks or other infections, some children developed meningitis, a serious inflammation of the membranes covering the brain. Additionally, many children who did not need a drainage tube before surgery found that they needed one afterward because fluid began to build up in their brains. The overall picture showed that while the surgery saved lives, the immediate recovery period was fraught with challenges that required constant vigilance.
The researchers then dug deeper to find the reasons behind these difficulties. They discovered that two specific conditions present before the surgery were the strongest predictors of trouble. The first was a ruptured sac. When the thin covering over the nerves was already broken when the child arrived at the hospital, the risk of complications was significantly higher. The second factor was the size of the opening in the spine. Children with a defect larger than five centimeters faced a much greater chance of wound problems and fluid leaks than those with smaller openings. The data showed that these two factors acted independently; whether a child was older or younger, or had other health issues, the state of the sac and the size of the hole were the most reliable indicators of what would happen next.
The study also highlighted a reality of medical care in resource-limited settings: the timing of the surgery. The average child in this group was about 12 months old when they finally received their repair, which is much later than the ideal window of a few days after birth. The authors noted that this delay likely contributed to the high rate of wound issues, as the exposed nerves had been sitting out for a long time, making the tissue more fragile and prone to infection. While the surgery itself was performed with care, the researchers found that the condition of the tissue at the time of the operation mattered more than the timing alone. They concluded that for children with a broken sac or a large hole, the path to recovery is particularly steep, requiring extremely careful surgical techniques and close monitoring after the operation to prevent the most serious outcomes.
