Peña Course: The 69th Workshop for the Surgical Treatment of Anorectal Malformations and Hirschsprung Disease in Children

Where comprehensive care, personalized attention and world-class experience meet to treat patients with complex colorectal disorders.



Next Colorectal Workshop: April 28 to May 1, 2025

Led by Alberto Peña, MD, Andrea Bischoff, MD, and Luis De La Torre, MD, renowned pediatric surgeons from the International Center for Colorectal and Urogenital Care at Children's Hospital Colorado, the Surgical Treatment of Anorectal Malformations and Hirschsprung Disease in Children is a four-day intensive workshop. This course combines our previous Peña Course (for both doctors and nurses) and Hirschsprung Disease Course into one comprehensive program. In this workshop, our surgeons will pass on their decades of experience and knowledge to help nurses, doctors and surgeons provide excellent surgical care and avoid common mistakes associated with these complex colorectal surgeries.

The workshop includes:

  • Operative demonstrations with detailed explanation and follow-up discussions
  • Discussions on diagnosis, surgery “error-traps,” how to recognize indications for re-operative surgery and post-op management including short- and long-term care and bowel management
  • Discussions on management of associated urologic and gynecologic problems
  • Learning how to diagnosis fecal incontinence and constipation and the difference in their management
  • Reviewing wound and ostomy care techniques for nurses
  • Lectures from multidisciplinary specialists in Urology, Gynecology, Radiology, Transition of Care, Psychology and Social Work

This will be the 69th workshop of its kind and is a must for any medical professional passionate about providing the best care for children with colorectal and urogenital conditions. Specifically, the curriculum for this ambitious program focuses on the three most common anorectal malformations facing pediatric surgeons today:

  • Male patients with a recto-urethral-bulbar fistula
  • Female patients with a recto-vestibular fistula
  • Cloaca anomaly with a short channel —less than 3 cm

All these anomalies have the potential for an excellent functional prognosis following a technically correct operation. However, surgeons doing these procedures are also susceptible to technical errors or “error traps” that can be major pitfalls for younger surgeons.

During the workshop, we’ll perform operative demonstrations in the mornings, allowing for time in the afternoons for discussion regarding the diagnosis and perioperative management of patients with anorectal malformations and special emphasis on bowel management. We’ll also point out error traps in great detail during our operative demonstrations so that attendees clearly understand their presence and how important they are to avoid. During these sessions, attendees will learn the importance of having a multidisciplinary team when caring for these patients through lectures from specialists from a range of disciplines.

This year we’re excited to add a day to our course, with no additional cost, to include Hirschsprung Disease with a focus on diagnosis, types of operations, tips and tricks for a successful surgical technique, histopathology, radiology and post-operative long-term management.

It has been our distinct honor to teach the techniques and principles of an operative procedure to which we have dedicated our entire careers. And it is our sincerest hope that your surgical fellows will allow us to share with them what we have learned over decades of providing compassionate care.
