Premier pediatric colorectal program opens doors at Children’s National

“With the broad range of expertise at Children’s National, including the nation’s best NICU, I’m confident that colorectal patients will get better, integrated care faster and more effectively here than anywhere else in the world,” says Marc Levitt, M.D.

World-renowned surgeon opens first program for care and treatment of colorectal conditions in the mid-Atlantic.

A new, highly-specialized surgical program at Children’s National Hospital is expected to draw patients from around the world. The colorectal surgery program is the first in the mid-Atlantic region to fully integrate surgery, urology, gynecology and gastroenterology into one cohesive program for children. The program is led by Marc Levitt, M.D., an internationally recognized expert in the surgical care and treatment of pediatric colorectal disorders who has performed over 10,000 surgeries to address a wide spectrum of problems involving the colon and rectum – more than any other full time practicing pediatric surgeon in the world.

“In the 25 years that I’ve been passionate about helping children with colorectal and pelvic conditions, I’ve learned that collaborative and integrated programs are the best way to care for them,” says Dr. Levitt. “With the broad range of expertise at Children’s National, including the nation’s best NICU, I’m confident that colorectal patients will get better, integrated care faster and more effectively here than anywhere else in the world.”

The program provides diagnosis and treatment for every type of colorectal disorder occurring in infants, children and adolescents, from the most common to the most complex. Every necessary specialty is integrated into the program in one convenient location to provide seamless care for all colon and rectum conditions, with particular expertise in:

  • Anorectal malformations
  • Cloacal malformations
  • Chronic constipation and fecal incontinence
  • Fecal and urinary incontinence related to spinal conditions such as spina bifida
  • Hirschsprung disease
  • Motility disorders

“Every child receives a customized treatment plan to address his or her unique needs,” Dr. Levitt says about the program. “Additionally, our surgeons often combine complex procedures across specialties to reduce the number of surgeries a child requires. It isn’t unusual for us to include urology, gynecology, and gastroenterology teams in the operating room alongside the colorectal surgeons so multiple issues can be addressed in a single procedure – we know that when possible, fewer surgeries is always better for the child.”

Dr. Levitt has cared for children from 50 states and 76 countries. He is the founder of Colorectal Team Overseas (CTO), a group of international providers who travel to the developing world to provide care for patients and teaching of their physicians and nurses. He co-founded the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC), an organization of collaborating colorectal centers across the globe.

“We’re absolutely thrilled to welcome Marc Levitt and launch the comprehensive colorectal program under his expert leadership,” adds Anthony Sandler, M.D., surgeon-in-chief and vice president of the Joseph E. Robert, Jr., Center for Surgical Care at Children’s National. “There are few in the world who can provide the expertise and leadership in colorectal diagnoses and treatment that Marc brings with him to Children’s. Many children and families from the region and from around the world will benefit from his expertise and from the program in general.”

“By advancing our understanding of the genetic causes and the anatomic differences among patients, the real goal of this research is to generate knowledge that will allow us to take better care of children with hypospadias,” Daniel Casella, M.D. says.

Daniel Casella, M.D., a urologist at Children’s National, was honored with an AUA Mid-Atlantic Section William D. Steers, M.D. Award, which provides two years of dedicated research funding that he will use to better understand the genetic causes for hypospadias.

With over 7,000 new cases a year in the U.S., hypospadias is a common birth defect that occurs when the urethra, the tube that transports urine out of the body, does not form completely in males.

Dr. Casella has identified a unique subset of cells in the developing urethra that have stopped dividing but remain metabolically active and are thought to represent a novel signaling center. He likens them to doing the work of a construction foreman. “If you’re constructing a building, you need to make sure that everyone follows the blueprints.  We believe that these developmentally senescent cells are sending important signals that define how the urethra is formed,” he says.

His project also will help to standardize the characterization of hypospadias. Hypospadias is classically associated with a downward bend to the penis, a urethra that does not extend to the head of the penis and incomplete formation of the foreskin. Still, there is significant variability among patients’ anatomy and to date, no standardized method for documenting hypospadias anatomy.

“Some surgeons take measurements in the operating room, but without a standardized classification system, there is no definitive way to compare measurements among providers or standardize diagnoses from measurements that every surgeon makes,” he adds. “What one surgeon may call ‘distal’ may be called ‘midshaft’ by another.” (With distal hypospadias, the urethra opening is near the penis head; with midshaft hypospadias, the urethra opening occurs along the penis shaft.)

“By advancing our understanding of the genetic causes and the anatomic differences among patients, the real goal of this research is to generate knowledge that will allow us to take better care of children with hypospadias,” he says.

Parents worry about lingering social stigma, since some boys with hypospadias are unable to urinate while standing, and in older children the condition can be associated with difficulties having sex. Surgical correction of hypospadias traditionally is performed when children are between 6 months to 1 year old.

When reviewing treatment options with family, “discussing the surgery and postoperative care is straight forward. The hard part of our discussion is not having good answers to questions about long-term outcomes,” he says.

Dr. Casella’s study hopes to build the framework to enable that basic research to be done.

“Say we wanted to do a study to see how patients are doing 15-20 years after their surgery.  If we go to their charts now, often we can’t accurately describe their anatomy prior to surgery.  By establishing uniform measurement baselines, we can accurately track long-term outcomes since we’ll know what condition that child started with and where they ended up,” he says.

Dr. Casella’s research project will be conducted at Children’s National under the mentorship of Eric Vilain, M.D., Ph.D., an international expert in sex and genitalia development; Dolores J. Lamb, Ph.D., HCLD, an established leader in urology based at Weill Cornell Medicine; and Marius George Linguraru, DPhil, MA, MSc, an expert in image processing and artificial intelligence.
