Insights
Punch Excision of Epithelialized Tracts (PEET) offers a novel, effective method for treating persistent pediatric gastrocutaneous fistulas (GCF). This minimally invasive technique shows promise for efficient GCF management with no observed complications in a small patient group.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Minimally Invasive Procedures
Background:
- Persistent gastrocutaneous fistula (GCF) is a frequent challenge in pediatric patients.
- Current management options for pediatric GCF include open surgery and medical treatments.
- A novel technique, Punch Excision of Epithelialized Tracts (PEET), is introduced for GCF excision.
Purpose of the Study:
- To describe a novel adaptation of a punch biopsy technique for excising pediatric GCF.
- To evaluate the short-term efficacy and safety of the PEET approach.
- To assess the potential for resource utilization and time efficiency of the PEET procedure.
Main Methods:
- The PEET technique involves using a punch biopsy tool passed over a Foley catheter.
- The catheter is inserted into the GCF tract, balloon inflated, and retracted.
- The punch biopsy instrument excises the tract circumferentially.
Main Results:
- Four pediatric patients with persistent GCF underwent the PEET procedure.
- The mean duration of GCF prior to intervention was 9 months.
- No post-operative complications were reported in the cohort during a mean follow-up of 7.8 months.
Conclusions:
- The PEET approach demonstrates short-term efficacy in managing pediatric GCF.
- This technique may offer advantages in terms of hospital resource utilization and procedure time.
- Further investigation in larger cohorts is warranted to confirm these preliminary findings.
Background:
Persistent Gastrocutaneous Fistula (GCF) is common problem encountered in the pediatric population. Several management options for intervening on pediatric persistent GCF have been described and range from open surgical management to medical management. Here we describe a novel adaptation on a previously described technique that utilizes a punch biopsy to excise the GCF we have coined as Punch Excision of Epithelialized Tracts (PEET).
Methods:
The steps to this procedure include passing a punch biopsy tool over a Foley catheter. The catheter is inserted into the GCF tract, the balloon is inflated, the catheter is retracted against the abdominal wall, and the punch biopsy instrument is pushed through the skin and subcutaneous tissue circumferentially excising the tract.
Results:
Four patients at our institution have undergone GCF excision using the PEET approach. Mean duration of the GCF in our four patients was 9 months. Mean follow-up after GCF excision using the PEET approach was 7.8 months. No patients in the cohort had any post-operative complications including surgical site wound infection, emergency department visits, or re-hospitalizations related to their surgical care.
Conclusion:
Based on our preliminary findings in this small patient cohort, we believe the PEET approach for managing persistent pediatric GCF has short-term efficacy and has the potential upside of utilizing fewer hospital resources to perform the procedure in a time-efficient manner.
