identified. A 19-G needle was used to puncture the balloon. Contrast medium was injected through the needle under fluoroscopy to confirm the needle position within the small bowel. A second 0.035-inch hydrophilic wire was advanced through the needle and coiled within the lumen of the bowel. A needle-knife was used to dissect the fistulous tract. A 4 mm  4 cm balloon was used to dilate the fistulous tract. A 15 mm  10 mm lumen-apposing metal stent was then deployed under a combination of fluoroscopic, endoscopic, and echosonographic guidance (Fig. 1) (Video 1, available online at www.giejournal.org). The stent position was confirmed by direct endoscopic visualization and on fluoroscopy. A controlled radial expansion balloon was used to dilate the lumen of the stent to 13.5 mm. The patient’s obstructive symptoms improved immediately after the procedure. She was given a liquid diet on postoperative day 1.

Cholangioscopy-assisted photodynamic therapy for cholangiocarcinoma

Figure 1. Cholangioscopy demonstrating diffuse necrosis of the biliary cancer after PDT.

A 62-year-old man with unresectable cholangiocarcinoma underwent ERCP with photodynamic therapy (PDT) under cholangioscopic guidance. Forty-eight hours before this pro-

cedure, the patient was injected with Photofrin (Pinnacle Biologics, Bannockburn, Ill), the only photosensitizer currently approved by the U.S. Food and Drug Administration (FDA).

Fluoroscopy and cholangioscopy were used in conjunction to accurately place a plastic fiber to treat the malignant stricture. Red light photoactivation through the plastic fiber leads to targeted necrosis of the cancer cells charged with Photofrin. Biliary stenting of the treated stricture was conducted after PDT. After 3 months, the patient underwent a repeat PDT session per protocol, and the stents were replaced. Cholangioscopy revealed diffuse necrosis, remodeling of the stricture, and an increased diameter induced by PDT (Video 1, available online at www.giejournal.org). The patient had 3 more sessions of PDT and survived on a chemoradiation regimen for 13 months. PDT is an attractive, palliative option for patients with unresectable cholangiocarcinoma. In many studies, patients undergoing PDT showed an increased survival rate compared with conventional stenting alone. As demonstrated in Video 1,

the combination of fluoroscopy and cholangioscopy appear synergistic in providing accurate and effective intraductal therapy. PDT is currently not FDA approved for palliation of cholangiocarcinoma; a randomized control trial is required and is currently under preparation (Fig 1).
