Endoscopic closure of persistent gastrocutaneous fistula in children

An Evaluation of Pediatric Gastrocutaneous Fistula Closure Through the Punch Excision of Epithelized Tract Procedure

BACKGROUND

Persistent gastrocutaneous fistulae frequently complicate gastrostomy tube placement. A minimally invasive technique for tract closure employing balloon catheter retraction and punch excision of the epithelized tract (PEET) was recently reported. We hypothesized the PEET technique of closure would lead to decreased complications without an increased incidence of recurrence.

METHODS

We conducted a single-center retrospective cohort study evaluating children who underwent gastrocutaneous fistula (GCF) closure 1/1/2018-12/31/2021, comparing patients who underwent the PEET procedure to those repaired with layered closure. Procedure duration and outcomes were additionally compared to the 2018-2019 National Surgical Quality Improvement Program (NSQIP) Participant Use File (PUF) database.

RESULTS

Sixty-two children underwent operative GCF closure, including 25 with PEET and 37 traditional layered closure. Procedural time was significantly decreased employing PEET (14 vs 26 minutes, P < .0001), less than half the national median by the NSQIP PUF database of 292 GCF closures (14 vs 34.5 minutes, P < .0001). Those repaired with the PEET method experienced no episodes of recurrence, surgical site infection, readmission, reoperation, or mortality within 30 days of the procedure. Conversely, in traditional closure, there was a 24.3% complication rate, including 7 surgical site infections, 1 readmission, and 2 unplanned reoperations. National procedural complication rate by NSQIP PUF was 5.5%, with a 4.8% rate of surgical site infection, .3% reoperation incidence, and .3% mortality.

DISCUSSION

Our study suggests GCF closure employing the PEET procedure is a safe, more efficient method of tract closure than the traditional layered closure technique.

The PEET procedure: Punch Excision of Epithelialized Tracts for gastrocutaneous fistula closure

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.

Endoscopic titanium clip closure of gastric fistula after splenectomy: A case report

This report describes a 52-year-old male patient with blunt abdominal traumatic rupture of the spleen due to injuries sustained in an automobile accident. Following splenectomy, the patient developed a gastric fistula. He underwent a long period of conservative treatment, including antibiotics and total parenteral nutrition, which was ineffective. The fistula could not be closed and titanium clip closure using a gastroscopy was then performed in order to close the fistula. After endoscopic therapy and clipping surgery, the patient’s general condition improved significantly, and he had no post-procedural abdominal complications. On post-clipping day 6, the gastric fistula was completely closed as shown by X-ray examination of the upper digestive tract. The patient was discharged from hospital and no complications were observed during the six-month follow-up period. Our report suggests that titanium clip closure using endoscopy may be the choice of treatment in patients with a gastric fistula.

Gastrocutaneous fistulae in children - A systematic review and meta-analysis of epidemiology and treatment options

BACKGROUND

Gastrostomy tubes are a common adjunct to the care of vulnerable pediatric patients. This study systematically evaluates the epidemiology and risk-factors for gastrocutaneous fistulae (GCF) after gastrostomy removal in children and reviews treatment options focusing on nonoperative management (NOM).

METHODS

After protocol registration (CRD-42017059565), multiple databases were searched. Studies describing epidemiology in children and GCF treatment at any age were included. Critical appraisal was performed (MINORS risk-of-bias assessment tool). One-sided meta-analysis was executed to estimate efficacy of therapeutic adjuncts using a random-effects model.

RESULTS

Sixteen articles evaluating pediatric GCF were identified. 44% defined GCF as persistence >1month which occurred in 31±7% of cases. Risk factors for pediatric GCF include age at gastrostomy, timing of removal, open technique, and fundoplication. Mean MINORS score was 0.60±0.16. Seventeen additional studies were identified reporting 142 patients undergoing NOM (endoscopic, systemic, and local therapies), and one pediatric comparative study was identified. Overall aggregate proportion of GCF closure after any NOM is 77% (80% success rate in local/systemic therapies; 75% success rate in endoscopic approaches). No adverse events were reported.

CONCLUSION

Persistent GCF complicates the management of gastrostomies in 1/3 of children with predictable risk factors. Several treatment options exist that obviate the need for general anesthesia. Their efficacy is unclear. Further prospective investigations are clearly warranted.
