Closure of a nonhealing gastrocutaneous fistula using an endoscopic clip

Endoscopic closure of persistent gastrocutaneous fistula in children

PURPOSE

The incidence of persistent gastrocutaneous fistula (GCF) after removal of gastrostomy tubes in pediatric patients is estimated to be up to 44 %. Our aim was to review the outcomes of GCF closure by an endoscopic technique that utilizes cautery and endoclips.

METHODS

A retrospective analysis of patients who underwent endoscopic treatment for persistent GCF from January 2010 to September 2013 was performed. This technique utilized esophagogastroduodenoscopy with cauterization of the fistula track and endoclipping of the gastric mucosa.

RESULTS

Sixteen patients underwent endoscopic treatment for persistent GCF. Mean age at time of endoscopy was 7.5 ± 5.5 (1.1-17) years. Gastrostomy tubes were in place for mean of 5.4 ± 5.2 (0.5-14.2) years prior to removal. The average time from gastrostomy tube removal to first endoscopic clipping was 6.7 ± 9 (0.1-28.9) months. Seven patients (44 %) had successful closure after one endoclipping procedure. Six patients underwent a second endoclipping procedure, with three successful closures. Four patients (25 %) required surgical closure for persistent fistulas and 2 (13 %) have continued drainage.

CONCLUSIONS

While endoscopy with cautery and endoclipping proves to be safe, many patients require multiple procedures and may require surgical closure. Patient selection and refinement of this technique may improve outcomes.

Enterocutaneous Fistula From A Billroth II Afferent Limb: Successful Closure With Endoclips

Recently, indications for endoscopic clips have expanded to include closure of gastrointestinal fistulae and perforations. A 62-year-old man with remote history of surgery for peptic ulcer underwent right hemicolectomy for a large hepatic flexure mass with proximal colonic dilatation. During surgery, inadvertent pinpoint duodenotomy of the afferent Billroth II limb resulted in a duodeno-cutaneous fistula. Despite total parental nutrition, cutaneous bile drainage persisted. The duodenal fistula was closed during upper endoscopy using three endoclips. Cutaneous bile drainage stopped, and the abdominal wall defect healed. This is the first published case of endoclip closure of an iatrogenic duodenal fistula from a Billroth II afferent limb.

Treatment of persistently leaking post PEG tube gastrocutaneous fistula in elderly patients with combined electrochemical cautery and endoscopic clip placement

OBJECTIVES

Persistent leakage from a gastrocutaneous fistula (GCF) created for the purpose of percutaneous endoscopic gastrostomy (PEG) tube placement is a common problem in elderly patients. Conservative methods often prove unsuccessful and surgical closure is usually not performed because of poor surgical risk. With advances in endoscopic technology, several nonsurgical approaches have emerged. These new methods have been reported in the past as case reports. The purpose of this study is to report a case series of eleven elderly patients with persistent leakage from gastrocutaneous fistulas who underwent combined electrochemical cautery and endoscopic clip placement.

METHODS

Eleven patients had failed conservative therapy and were deemed unsuitable candidates for surgical closure. Electric and chemical cauterization was used to de-epithelialize the fistulous tract. The edges of the internal orifice of the gastrocutaneous fistula were approximated using endoclips during an esophagogastroduodenoscopy. Patients were observed postprocedure for leakage.

RESULTS

This procedure resulted in complete closure of the gastrocutaneous fistula in nine patients (82%). One patient had partial closure of the fistula which was sealed using a new PEG tube.

CONCLUSION

Gastrocutaneous fistula is a common complication in elderly patients after removal of gastrostomy tubes. Simple endoscopic procedures have shown promising results in the treatment of this complication.

A Nasogastric Tube Inserted into the Gastrocutaneous Fistula

We reported a case in which a nasogastric tube was inserted into the gastrocutaneous fistula, diagnosed by abdominal computed tomography. A 78-year-old man with a history of recurrent cerebral hemorrhage had a percutaneous endoscopic gastrostomy tube due to dysphagia for 2 years. However, soft tissue infection at the gastrostomy site caused the removal of the tube. Immediately, antibiotic agents were infused. For appropriate hydration and medication, a nasogastric tube was inserted. However, there was no significant improvement of the soft tissue infection. Moreover, the amount of bloody exudate increased. Abdominal computed tomography revealed the nasogastric tube placed under the patient's skin via gastrocutaneous fistula. The nasogastric tube was removed, and an antibiotic agents were maintained. After 3 weeks, the signs of infection fully improved, and percutaneous endoscopic gastrostomy was performed again. This case shows necessities of an appropriate interval between removal of the gastrostomy tube and insertion of a nasogastric tube, and suspicion of existence of gastrocutaneous fistula.

Over-the-scope clip closure of two chronic fistulas after gastric band penetration

Gastrointestinal perforations are conservatively managed at endoscopy by through-the-scope endoclips and covered self expandable stents, according to the size and tissue features of the perforation. This is believed to be the first report of successful closure of two gastro-cutaneous fistulas with over-the-scope clips (OTSCs). After laparoscopic gastric banding, a 45-year old woman presented with band erosion and penetration. Despite surgical band removal and gastric wall suturing, external drainage of enteric material persisted for 2 wk, and esophagogastroduodenoscopy demonstrated two adjacent 10-mm and 15-mm fistulous orifices at the esophagogastric junction. After cauterization of the margins, the 10-mm fistulous tract was grasped by the OTSC anchor, invaginated into the applicator cap, and closed by a traumatic OTSC. The other 15-mm fistula was too large to be firmly grasped, and a fully-covered metal stent was temporarily placed. No leak occurred during the following 6 wk. At stent removal: the OTSC was completely embedded in hyperplastic overgrowth; the 15-mm fistula significantly reduced in diameter, and it was closed by another traumatic OTSC. After the procedure, no external fistula recurred and both OTSCs were lost spontaneously after 4 wk. The use of the anchor and the OTSC seem highly effective for successful closure of small chronic perforations.

Closure of a nonhealing gastrocutanous fistula using argon plasma coagulation and endoscopic hemoclips

A case in which a gastrocutaneous fistula developed after percutaneous endoscopic gastrostomy tube placement is presented. The fistula was first managed conservatively, then was closed by argon plasma coagulation and hemoclip placement. The patient was observed and was discharged once the gastrocutaneous fistula closed.

Endoscopic fibrin sealing of gastrocutaneous fistulas after sleeve gastrectomy and biliopancreatic diversion with duodenal switch

BACKGROUND AND AIM

Gastrocutaneous fistulas (GCF) are uncommon complications accounting for 0.5-3.9% of gastric operations. When their management is not effective, the mortality rate is high. This study reports the conservative treatment of GCF in morbidly obese patients who underwent biliopancreatic diversion with duodenal switch.

METHODS

Ninety-six morbidly obese patients were treated in our department with biliopancreatic diversion with duodenal switch (Marceau technique) and, in six of them, a high-output GCF developed. A general protocol was applied to all patients presenting a GCF. Everyone was treated by total parenteral nutrition (TPN) and somatostatin for at least 7 days after the appearance of the leak. If the leak continued, then fibrin glue was used as a tissue adhesive. Endoscopic application of the sealant was accomplished under direct vision via a double-lumen catheter passed through a forward-viewing gastroscope.

RESULTS

All patients were treated successfully with conservative treatment (either solely with TPN and somatostatin, or with endoscopic fibrin sealing sessions). No evidence of fistula was observed at gastroscopy 3 and 24 months after therapy.

CONCLUSION

The conservative treatment of GCF following biliopancreatic diversion with duodenal switch is highly effective. All patients should enter a protocol that includes TPN and somatostatin. When the GCF persist, endoscopic sealing glue should be considered before operation because it is simple, safe, effective and, in some cases, life-saving. Therefore, conservative treatment should be employed as a therapeutic option in GCF developing after bariatric surgery.

Successful tubes treatment of esophageal fistula

AIM

To discuss the merits of "tubes treatment" for esophageal fistula (EF).

METHODS

A 66-year-old female who suffered from a bronchoesophageal and esophagothoratic fistula underwent a successful "three tubes treatment" (close chest drainage, negative pressure suction at the leak, and nasojejunal feeding tube), combination of antibiotics, antacid drugs and nutritional support. Another 55-year-old male patient developed an esophagopleural fistula (EPF) after esophageal carcinoma operation. He too was treated conservatively with the three tubes strategy as mentioned above towards a favorable outcome.

RESULTS

The two patients recovered with the tubes treatment, felt well and became able to eat and drink, presenting no complaint.

CONCLUSION

Tubes treatment is an effective basic way for EF. It may be an alternative treatment option.
