Peter Mattei, MD, FACS, FAAP

Attending Physician, Division of General, Thoracic and Fetal Surgery

Associate Professor of Surgery, The Perelman School of Medicine at the University of Pennsylvania

I am an attending physician in the Division of General, Thoracic and Fetal Surgery at The Children’s Hospital of Philadelphia and assistant professor of surgery at The Perelman School of Medicine at the University of Pennsylvania. As the primary surgical liaison for pediatric surgical oncology, I am a member of CHOP’s Tumor Board and participate in clinical decision-making discussions for many children with pediatric solid tumors being treated or evaluated for a second opinion at CHOP. I have developed special expertise in the surgical treatment of neuroblastoma, Wilms’ tumor, hepatoblastoma, and abdominal and thoracic sarcomas, among other pediatric solid tumors.

One of the things I’m most proud of at CHOP is the partnership between surgeons, oncologists and other specialists through all stages of a child’s cancer treatment. Having a multidisciplinary team of experts in every specialty, working together to develop a complete care plan that takes into consideration all aspects of a child’s treatment and recovery, allows us to best serve the individual patient and ultimately produces better outcomes.

The Children’s Hospital of Philadelphia has long been a pioneer in pediatric surgery and that continues today. We are at the forefront of many of the newest protocols, including the very exciting field of robotic surgery. I have a particular interest in daVinci robotic-assisted laparoscopy and thoracoscopy, which are minimally invasive and enable unprecedented surgical precision.

I also work very closely with the gastroenterologists at CHOP and perform many operations to help children and adolescents with Crohn’s disease, ulcerative colitis, familial adenomatous polyposis and GERD. These include: laparoscopic bowel resection and anastomosis; colectomy and proctectomy with J-pouch ileo-anal reconstruction; anorectal examination under anesthesia for incision and drainage of perirectal abscess or placement of a seton for anal fistula; operations for ileostomy or colostomy; laparoscopic placement of a gastrostomy button; laparoscopic Nissen fundoplication; laparoscopic esophageal myotomy for achalasia; and laparoscopic-assisted pull-through for Hirschsprung's disease.

Paralleling my excitement about the coming of new technologies and techniques is my commitment to helping kids get better. What gratifies me about this work continues to be the children I treat. They are simply amazing and inspirational — and they get it. They know they have something very serious going on, yet they have an inner calm and appreciation for everything we do for them that is awe-inspiring and very humbling.
