What was supposed to be a routine circumcision has turned into a medical nightmare for a Long Island family after their newborn son suffered severe complications at a New York City hospital.

Cole Jordan Groth was born on March 31 at NewYork-Presbyterian Morgan Stanley Children’s Hospital. Though he was diagnosed with a congenital heart condition, he was otherwise doing well and was scheduled to be discharged to his home in Lake Grove on April 16 to meet his 2-year-old big brother.

Two days before that, doctors contacted his parents, Tim and Gabrielle Groth, to ask if they wanted their son circumcised. They agreed — but within hours of the procedure, the baby began to bleed heavily, had seizures, and suffered multiple organ injuries, according to his father.

“What happened was a parent’s worst nightmare,” Tim Groth, 35, told The New York Post on Monday.

When Gabrielle returned to the hospital on April 15 to review discharge paperwork, she found her baby boy pale, screaming, and unresponsive. Over the following 10 days, Cole endured daily blood transfusions and multiple surgeries, including one to remove damaged sections of his intestines caused by blood loss.

Now in critical condition, Cole is on a respirator, being fed intravenously, and using a colostomy bag. “He looks like he’s been through war,” his father said. “Part of me is angry. Part of me is just heartbroken. All of this was avoidable.”

Tim Groth has since filed a formal grievance with the hospital, demanding answers. He claims a nurse discovered Cole’s excessive bleeding at around 2:30 a.m. on April 15, but blood work wasn’t ordered until after 5 a.m., and the attending doctor wasn’t informed until 8:30 a.m. during a shift change.

“They failed to act quickly enough,” Groth said. “You don’t go from a routine circumcision to near-death without something going very wrong.”

Cole now faces a long and uncertain road to recovery. He’ll likely remain in the cardiac neonatal intensive care unit for several more months. Doctors hope to eventually reconnect his intestines and remove the colostomy bag, but his parents are preparing for potential long-term complications.

Despite the trauma, there have been a few positive signs: Cole hasn’t needed a blood transfusion in several days. Still, the family remains on edge. “I spent so many days just crying,” Groth said. “Now, it’s about facing what’s next — and what other complications might come.”

The family launched a GoFundMe campaign on April 19 to help cover Cole’s mounting medical expenses. As of Monday afternoon, donations had already exceeded their $50,000 goal, reaching nearly $60,000.

Groth, the CEO of a Long Island pain management practice founded by his father, said several family members in the medical field believe the hospital failed to meet the standard of care and didn’t act with appropriate urgency.

While the hospital staff has shown empathy, Groth says they’ve carefully avoided admitting fault. “They’ve chosen their words very carefully,” he said. A hospital spokesperson declined to comment, citing patient privacy policies.

The family hasn’t taken legal action yet, but Groth isn’t ruling it out. “Right now, we’re just trying to make sure he survives,” he said.
