EUS-guided gallbladder drainage as second option of biliary decompression after failed ERCP for the management of malignant distal biliary obstruction.

Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is recommended as a rescue treatment of malignant distal biliary obstruction (MBDO) after failed ERCP and endoscopic ultrasound-guided biliary drainage (EUS-BD). A 64-year-old male was admitted for painless obstructive jaundice and anemia. For religious reasons, he refused any blood transfusions. Abdominal computed tomography scan showed a pancreatic tumor with dilation biliary tree and liver metastasis. ERCP failed and advanced biliary cannulation technique such as precut were avoided due to a high risk of bleeding. We avoided the two transmural EUS-BD approaches, which include EUS-guided choledochoduodenostomy and EUS-guided hepaticogastrostomy, due to smaller targets and considered riskier in this patient. Since the gallbladder was markedly distended and the cystic duct was patent, we performed a cholecystogastrostomy with a 15x10 mm electrocautery lumen-apposing metal stent (EC-LAMS) as a second option of biliary drainage. After a week, the serum bilirubin levels decreased to normal values and the patient was uneventfully discharged. At follow-up, he refused to receive chemotherapy and died six months later due to cancer progression.

Endoscopic management of an iatrogenic duodenal perforation and choledocholithiasis in the same endoscopic retrograde cholangiopancreatography session.

We present the case of a 67-year-old female with recent cholecystectomy for symptomatic cholelithiasis. She was admitted to our hospital with right upper quadrant abdominal pain and vomiting. Laboratory analysis revealed hyperbilirubinemia with cytolysis and cholestasis. Abdominal ultrasound revealed a choledocholithiasis of 8 mm. Endoscopic retrograde cholangiopancreatography (ERCP) was scheduled. With the duodenoscope, after the reduction maneuver from the second duodenal portion to face the major papilla, a perforation of approximately 18 mm was identified in the contralateral wall distal to it. A gastroscope identified the perforation and a 9.5-11 x 6 mm over-the-scope-clip (OTSC) was placed after inserting its edges into the cap with aspiration (without approximation forceps).

EUS-guided gallbladder drainage as a treatment for acute perforated cholecystitis.

Acute perforated cholecystitis is a rare but severe complication of acute cholecystitis. Currently, EUS-GBD using LAMS is the preferred choice for gallbladder drainage in high-risk surgical patients with acute cholecystitis unfit for cholecystectomy. However, it has been suggested to avoid this procedure when there is suspicion of gallbladder perforation or necrosis. The evidence of EUS-GBD in this setting is scarce. Our case demonstrates that EUS-GBD with LAMS can be effective in the management of type II perforation of the gallbladder.

Risk of neoplastic change in large gastric hyperplastic polyps and recurrence after endoscopic resection.

BACKGROUND: Gastric hyperplastic polyps (GHPs) have a risk of neoplastic transformation reaching 5 %. Current endoscopic resection techniques appear suboptimal with a high risk of local recurrence. This study assessed the outcomes of endoscopic resection for GHPs and identified risk factors for recurrence and neoplastic transformation. METHODS: This retrospective, multicenter, European study included adult patients with at least one GHP ≥ 10 mm who underwent endoscopic resection and at least one follow-up endoscopy. Patients with recurrent GHPs or hereditary gastric polyposis were excluded. All data were retrieved from the endoscopy, pathology, and hospitalization reports. RESULTS: From June 2007 to August 2018, 145 GHPs in 108 patients were included. Recurrence after endoscopic resection was 51.0 % (74 /145) in 55 patients. R0 resection or en bloc resection did not impact the risk of polyp recurrence. In multivariate analysis, cirrhosis was the only risk factor for recurrence (odds ratio [OR] 4.82, 95 % confidence interval [CI] 1.33 - 17.46; P = 0.02). Overall, 15 GHPs (10.4 %) showed neoplastic transformation, with size > 25 mm (OR 10.24, 95 %CI 2.71 - 38.69; P < 0.001) and presence of intestinal metaplasia (OR 5.93, 95 %CI 1.56 - 22.47; P = 0.01) being associated with an increased risk of neoplastic transformation in multivariate analysis. CONCLUSIONS: Results confirmed the risk of recurrence and neoplastic transformation of large GHPs. The risk of neoplastic change was significantly increased for lesions > 25 mm, with a risk of high grade dysplasia appearing in polyps ≥ 50 mm. The risk of recurrence was high, particularly in cirrhosis patients, and long-term follow-up is recommended in such patients.
