Closure was accomplished endoscopically using a physician prepared polyglactin absorbable patch. After APC mucosal ablation, the patches were pressed into the fistulas from within the GI tract and multiple clips were used to fix them in

place. A temporary coated esophageal stent was used in the esophageal case to hold the patch in place. All were successful in effecting immediate closure. Cases are presented in increasing order of dificulty. No complications or untoward events occurred. Clinical polyglactin patch placement appears to be an, inexpensive endoscopic procedure using readily available surgical learn more materials. This new procedure ads to the endoscopist’s arsenal of techniques in dealing with GI fistulas following surgery. Comparative trials to other newly described endoscopic techniques are warranted. “
“69-year-old woman with severe necrotizing pancreatitis, status-post 3 transgastric direct endoscopic necrosectomy procedures for treatment of a large

infected necrotic cavity abutting the left colon, was rehospitalized 3 weeks later with abdominal pain, diarrhea, fever and recurrent fluid collection on CT. Residual necrotic material was debrided further, but repeat endoscopy 3 days later showed reflux of fecal-like material into the debrided cavity and apparent communication with Antidiabetic Compound Library price the left colon on fluoroscopy. A subsequent hypaque enema demonstrated contrast extravasation into the pancreatic bed in addition to a long sigmoid stricture, likely a result of chemical (pancreatic secretions) injury. The diagnosis of pancreatico-colonic fistula was entertained for which traditional management is surgical repair, as spontaneous closure is rare and persistent infection can be life-threatening.

In this case, an attempt at endoscopic localization and closure of the fistula was performed. A pediatric colonoscope was advanced past the sigmoid stricture following balloon dilation (15 mm) into an Adenosine triphosphate inflamed left colon. With the colonoscope in place, an upper endoscope was advanced through a gastrostomy into the debrided cavity for instillation of radio-opaque contrast material and methylene blue (MB), which highlighted and facilitated location of 2 small fistulous openings seen at colonoscopy. A TTS clip was placed just above the more proximal fistula. Next, a therapeutic upper endoscope was fitted with an OTSC device, requiring creative TTS balloon insertion and dilation through the OTSC device to pass the sigmoid stricture. Using the TTS clip as a marker, the most proximal fistula was identified and closed with the OTSC. Procedural maneuvers were repeated for OTSC closure of the second fistula. Successful fistula closure was confirmed fluoroscopically and endoscopically by absence of leak into the colon following repeat contrast and MB instillation in the cavity. The patient was discharged from the hospital 3 days later.
