A 75-year-old woman with end-stage liver disease and recurrent calculous cholecystitis, treated with a percutaneous cholecystostomy tube (PCT) because of her poor surgical candidacy, was referred for alternative gallbladder drainage. Two prior tube dislodgments causing abdominal pain had significantly affected her quality of life (Video 1, available online at www.VideoGIE.org). After careful multidisciplinary evaluation, a decision was made to endoscopically internalize the gallbladder drainage in replacement of the PCT.
Sinography revealed patent cystic and common bile ducts (Fig. 1A). A CT scan revealed cholelithiasis and a cirrhotic liver (Fig. 1B). Despite duct patency, gallbladder drainage was necessary to prevent future calculous cholecystitis. A nondistended gallbladder rendered secure transenteric access challenging. Moderate thrombocytopenia and increased international normalized ratio (INR) were noted (platelets: 63 × 109/L; INR: 1.4). Gastroesophageal varices were not visualized on EGD. During EUS, a satisfactory window without venous collaterals was achieved from the duodenal bulb. Copious amounts of sterile saline solution were injected through the PCT to distend the gallbladder, optimizing visualization (Fig. 1C). The gallbladder was punctured with a 19-gauge EUS needle (Figs. 1D and E), and a 0.035-inch guidewire was subsequently passed through it, creating 3 loops of wire within the gallbladder to ensure adequate access (Fig. 1F). The EUS needle was exchanged for the fully covered lumen-apposing metal stent (LAMS) (HotAxios Stent, 15 × 10 mm, Boston Scientific, Natick, Mass). One hundred watts in pure cutting mode were applied to advance the catheter. However, excessive looping of the wire made progression unfeasible. The wire was slightly pulled back, and with the application of cautery, the catheter was advanced smoothly. The distal and proximal flanges of the stent were deployed under endosonographic and endoscopic guidance, respectively (Figs. 1G and H). Injection of contrast material from the PCT demonstrated secure transenteric communication (Fig. 1I). At 1-week follow-up, the patient was asymptomatic, and the PCT was successfully removed in clinic.
Long-term use of PCT in patients unfit for surgery can cause significant morbidity. LAMSs are being increasingly used in patients with acute and recurrent cholecystitis to internally drain the gallbladder. In this video, we demonstrate how the use of saline solution injection through the PCT helped distend the gallbladder, optimizing visualization and stent deployment. Successful EUS-guided internal gallbladder drainage was achieved in a patient with long-term troublesome PCT.
