Fox News Digital reached out to the Cook Children’s Medical Center for comment.

AmieLynn and JamieLynn were born prematurely on Oct. 3, 2022, at the Texas Health Harris Methodist Hospital Fort Worth, according to the medical center press release.

The twin girls were born at 34 weeks of gestation and reportedly weighed 4 pounds and 7.8 ounces.

Full-term pregnancies last between 37 and 42 weeks, according to the American College of Obstetricians and Gynecologists and the Society for Maternal Fetal Medicine.

"The separation surgery [has given] AmieLynn and JamieLynn better opportunities to improve their health and development, and to grow as the unique, individual little girls that they have been since birth, regardless of their physical connection as conjoined twins," Dr. Jose L. Iglesias, medical director of pediatric surgery at Cook Children’s Medical Center, said in a statement.

AmieLynn and JamieLynn were omphalopagus twins – meaning they were joined at the abdomen and shared one or more internal organs. 

The sisters "were joined from the lower part of the breastbone to their bellybutton" and they reportedly shared a liver, according to Cook Children’s Medical Center’s press release.

Iglesias, who was the lead surgeon for AmieLynn and JamieLynn, worked with the larger Cook Children’s Medical Center team to complete body scans, anatomy models, surgery maps, simulations, operation room preparation and surgical choreography rehearsals.

The medical experts who cared for AmieLynn and JamieLynn reportedly worked to improve the girls’ health, growth and development before the surgery could be done, including a focus on nutrition and proper function of their brain, heart, lungs and other vital organs.

"At this stage in AmieLynn and JamieLynn’s growth and development, this was the right time for them to have the surgery," Dr. Mary Frances Lynch, a neonatologist at Cook Children’s Medical Center, said in a statement.

"Separation now will benefit AmieLynn and JamieLynn by allowing them continue reaching important growth and development milestones in their individual health journeys," Lynch continued.

AmieLynn and JamieLynn are receiving post-surgery care from the Cook Children’s Medical Center neonatology and NICU departments, according to the hospital’s press release.

Their parents, Amanda Arciniega and James Finley, were present at Cook Children’s Medical Center on the surgery day and "patiently waited for news of their separation," the hospital reported.
