Miracle Surgery at AIIMS: Doctors successfully Separate incomplete Parasitic Twin

In a remarkable medical achievement, doctors at the All India Institute of Medical Sciences (AIIMS) successfully performed a complex surgery to remove a parasitic twin from a 17-year-old boy. The rare condition, seen in only 40 reported cases worldwide, had left the teenager, Mohit (name changed), with a fully developed extra limb attached to his abdomen since birth.

A Rare Medical Condition

Conjoined twins occur in approximately 1 in 50,000 to 100,000 births. In rare instances, one twin fails to fully develop, leading to what is known as an asymmetrical or parasitic twin. In such cases, the “autosite” (dominant twin) carries an underdeveloped twin that remains entirely dependent on its host. Mohit’s parasitic twin included a lower limb with underdeveloped male genitalia that grew as he grew. Surprisingly, he could feel sensations such as touch, pain, and temperature in the extra limb.

Throughout his childhood, Mohit endured immense social stigma and isolation due to his condition. Misconceptions about his deformity kept him from leading a normal life. Local doctors had previously advised him against surgery, fearing fatal complications due to shared blood supply. Unable to continue schooling beyond the 8th grade, he struggled with his circumstances until a relative suggested he seek help at AIIMS.

A Race Against Medical Challenges

Upon his arrival at AIIMS in January 2025, a team of specialists, including general surgeons, plastic surgeons, radiologists, and anesthesiologists, immediately took charge of his case. A detailed CT angiography revealed that the parasitic limb was supplied by a branch of the internal mammary artery, a rare and challenging vascular connection. Additionally, a large cystic mass was detected in his abdomen, complicating the case further.

After extensive discussions and preparation, the surgery was scheduled for February 8, 2025.

A Landmark Surgery

The procedure was carried out in two critical stages.

1. Removal of the Parasitic Limb:

Surgeons made a circular incision around the limb’s attachment site.

The blood vessels supplying the extra limb were carefully identified and tied off.

The bony attachment was surgically separated.

The underdeveloped testes of the parasitic twin were found within the soft tissue and removed.

2. Removal of the Cystic Mass:

A midline incision was made in the abdomen to access the mass.

The cystic structure, which was adherent to the abdominal wall, bowel, and liver, was carefully separated and removed.

Surgeons discovered that Mohit’s bladder extended abnormally high up to his belly button. This section of the bladder was carefully tied off and divided.

A surgical drain was placed in the abdomen before closing the incision.

A New Beginning

Mohit’s post-operative recovery was swift. He began eating the very next day, and by the third day, the surgical drain was removed. He was discharged from the hospital on the fourth day. For the first time in his life, he was free from the burden that had defined his existence.

At first, he found it hard to believe that the limb was gone, saying he could still feel its presence. His family, overwhelmed with emotion, shed tears of joy, grateful that he could now lead a normal life.

A Team Effort in Medical Excellence

This groundbreaking surgery was the result of extraordinary teamwork, led by Dr. Asuri Krishna (chief operating surgeon), along with Dr. VK Bansal, Dr. Sushant Soren, Dr. Brijesh Kumar Singh, Dr. Abhinav Kumar, Dr. Jaymeen Makwana (Surgical Disciplines), Dr. Manish Singhal, Dr. Sashank (Plastic Surgery), Dr. Ganga Prasad, Dr. Rakesh (Anesthesia), and Dr. Atin and Dr. Ankita (Radiology).

This historic surgical success highlights not only the power of modern medicine but also the resilience of the human spirit. Mohit’s journey from rejection and despair to hope and healing stands as an inspiration for countless others facing medical challenges.
