"This is only the fourth case of its kind in the world's medical history," SRM Global Hospitals said in a statement Thursday.

The boy, born at just 28 weeks to housewife Manju and daily wage laborer Murthy, underwent surgery under general anesthesia on the 23rd day after birth.

“The newborn baby was in the neonatal ICU since birth. On the 23rd day, there was swelling in the child's right inguinoscrotal area. We had to perform emergency surgery as the condition was life-threatening,” said Dr Saravana Balaji of the hospital.

Balaji explained that although neonatal hernia is relatively common in premature babies, Amyand's hernia is exceptionally rare in 0.42 percent of these babies.

“Perforated appendix is ​​even rarer, occurring in only 0.1 percent of Amyand's hernia cases. To date, only three such cases have been reported globally. Our prompt intervention was crucial in addressing this complex and rare condition,” he said.

The doctor said it was an extremely challenging surgery because like any other premature baby the boy also had an immature airway which made anesthesia more difficult and required precise management.

Additionally, the low birth weight of the baby requires special postoperative care in the NICU to ensure proper recovery and support.

The complex surgery which lasted for an hour was successful. The baby recovered, his weight increased to 2.06 kg and he was discharged in good general condition, the hospital said.
