Current Projects


Infant Perianal Abscess Quality Improvement Project

Currently enrolling patients

Perianal abscesses are very common in children under on year of age. These often recur and can be frustrating to treat for both families and caregivers. Current management may include incision and drainage, aspiration, observation, antibiotics, or a combination of these. There is no standard of care, and evidence-to-date is mixed with a wide range of reported recurrence rates from various methods of treatment. Our hypothesis is that implementation of a protocol for management of infant perianal abscesses that minimizes early surgical instrumentation will improve patient care, decreased time to abscess resolution and decreased use of surgical intervention.

Surgery in COVID-19 Positive Pediatric Patients

Enrollment completed

Since resumption of nearly "normal" activities and surgical procedures during the COVId-19 pandemic, children's hospitals have been faced to determine whether operations on COVID-19 positive children may be safe to perform or should be postponed. The literature is limited on rates of complications following surgery for patients who undergo operations while "asymptomatically" COVID-19 positive. Our objective is to document incidence of post-surgical complications for asymptomatic COVID-19 positive versus symptomatic COVID-19 positive children undergoing general surgical operations.

Appendicitis in the Time of COVID-19

Enrollment completed

The COVId-19 pandemic has caused disruption in many areas of healthcare, including ion patients suffering from appendicitis, cancer, and trauma. In a single-center retrospective review of pediatric appendicitis patients treated at Children's Memorial Hermann Hospital, in Houston, TX, the rate of perforated appendicitis increased from 23.7% to 42.5%. Given differences in nationwide practice patterns among pediatric surgeons and changes in these patterns secondary to concerns of COVID-19, we aimed to characterize the treatment of pediatric patients with appendicitis, evaluate the severity of appendicitis during the COVID-19 pandemic, and patient outcomes during this time.

Pilonidal Study

Currently enrolling patients

This study is a multi-center, non-randomized controlled trial. Pilonidal disease can be a frustrating condition, with a chronic and relapsing course. There is no clear optimal treatment. Minimally invasive pilonidal excision (MIPE) allows for a rapid return to activity following treatment, likely at a cost of higher recurrence. This is a prospective observational non-randomized clinical trial assessing different surgical treatments for pilonidal disease.  This trial allows for patient and/or surgeon to dictate the operation performed. Outcome measures, including need for second operative procedure, time to return to school/work, frequency of surgical complications, patient satisfaction and QOL will be captured. In addition, surgeon perspectives on the procedure will be studied. This study is registered on

ENhancing Recovery In CHildrens Undergoing Surgery (ENRICH-US)

Currently enrolling patients

ENhancing Recovery In CHildrens Undergoing Surgery (ENRICH-US) protocols have been found to decrease hospital length of stay, in-hospital costs, and complications for a wide variety of adult surgical populations.The objectives of this study are to demonstrate whether the implementation of a multi-faceted enhanced recovery protocol for children undergoing surgery for inflammatory bowel disease is feasible and safe as well as to assess the efficacy of the ERAS protocol by measuring clinical outcomes.
