Nairobi, October 23- Surgeons at Kenyatta National Hospital (KNH) have achieved a global medical milestone after successfully performing what is believed to be the world’s largest gigantomastia surgery, removing 20.86 kilograms of breast tissue from a 17-year-old girl in an intricate 11-hour operation.
The patient, Lydia Musivi, had battled the rare condition for about a year and a half, during which her breasts grew abnormally large causing severe back pain, recurring infections, and deep emotional distress. The excess tissue accounted for nearly 37 percent of her total body weight, leaving her unable to walk properly, attend school, or lead a normal life.
According to KNH, the life-changing procedure took place on September 22, 2025, marking a landmark achievement in reconstructive and plastic surgery in Kenya.
After the surgery, Lydia expressed overwhelming relief and renewed optimism.
“The weight is finally gone. I feel lighter and ready to go back to school,” she said. “Now I can live freely and pursue my dream of becoming a teacher.”
The complex operation was led by Dr. Benjamin Wabwire, Head of Specialized Surgery and Consultant Plastic and Reconstructive Surgeon at KNH, who hailed the success as both a medical and emotional victory.
“This was not just a surgical success it was the restoration of dignity, hope, and a future for a young woman,” Dr. Wabwire said. “Our team proved that with skill and compassion, we can overcome even the most extraordinary medical challenges.”
The operation brought together a multidisciplinary team of Kenyan specialists and visiting experts Professor Lew and Dr. Kim from Yonsei University, South Korea. The anaesthesia team was headed by Dr. Eileen Towett and Dr. Hellen Mwari, with nurses Esther Munga and Eun Jin Chae playing vital roles throughout the marathon surgery.
Lydia’s mother, Naomi Mutendwa, recalled months of pain and uncertainty before they were referred to KNH from Garissa County Referral Hospital.
“I watched my daughter’s life fade under the weight of this illness. It broke her spirit,” she said. “The KNH doctors not only treated her they gave her back her confidence and her future.”
KNH Acting CEO Dr. Richard Lesiyampe celebrated the operation as proof that Kenya’s healthcare system is capable of world-class medical achievements.
“This success shows that groundbreaking medical procedures are possible right here in Kenya,” he said. “Our teams are solving local health challenges with global standards of excellence and compassion.”
Lydia has since been discharged and is recovering well at her home in Mwingi, Kitui County. She plans to return to school in January 2026, ready to reclaim her life and pursue her dreams after overcoming the condition that once held her back.
