Endoscopic Ultrasound Guidance

Objectives: Antibiotic therapy and percutaneous drainage have been the first-line treatments for liver abscesses. However, percutaneous drainage of abscesses may be challenging in difficult-to-access locations such as the caudate lobe. The aim of this review was to determine the indications, technical feasibility and efficacy of endoscopic ultrasound-guided drainage of difficult-to-access liver abscesses. Methods: A literature review of original articles, abstracts, case series and case reports describing endoscopic ultrasound-guided liver abscess drainage was performed. The indications, techniques and complications associated with endoscopic ultrasound-guided drainage were reviewed. Results: A total of 15 studies were identified. The main indications were failed antibiotic therapy and difficulty in gaining percutaneous access. The technique involved identification and puncturing of an abscess under endoscopic ultrasound guidance followed by placement of a prosthesis via a guide wire. The technique was 97.5% successful with no major complications reported. Conclusion: Endoscopic ultrasound-guided drainage was feasible and safe and allowed complete drainage of liver abscesses not accessible by percutaneous drainage.

Background and Aim. A successful endoscopic ultrasound guided rendezvous (EUS-RV) biliary drainage is dependent on accurate puncture of the bile duct and precise guide wire manipulation across the ampulla of Vater. We aim to study the feasibility of using a flexible 19-gauge fine aspiration needle in the performance of EUS-RV biliary drainage. Method. This is a retrospective case series of EUS-RV biliary drainage procedures at a single center. Patients who failed ERCP during the same session for benign or malignant biliary obstruction underwent EUS-RV using a flexible, nitinol covered, 19-gauge needle for biliary access and guide wire manipulation. Result. 24 patients underwent EUS-RV biliary drainage via extrahepatic access while 1 attempt was via intrahepatic access. The technical success rate was 80%, including 83.3% of cases via extrahepatic access. There was no significant difference in success rate of inpatient and outpatient procedures, benign or malignant indications, or type of guide wire used. Adverse events included mild pancreatitis (3 patients) and cholangitis (1 patient). Conclusion. A flexible 19-gauge needle for biliary access can be safe and effective when used to perform EUS-RV biliary drainage. Direct comparison between the nitinol needle and conventional metal needles in the performance of EUS guided biliary drainage is needed.

Background: Insulinoma is the most common neuroendocrine neoplasm of the pancreas, characterised by hypoglycaemic symptoms. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) and ethanol ablation (EUS-EA) are novel methods for treating insulinoma. We aimed to perform a systematic review to assess the efficacy and safety of EUS-guided ablation techniques for pancreatic insulinomas. Methods: We systematically searched for articles detailing EUS-guided ablations of insulinomas. We performed a qualitative analysis and summarised data on the efficacy and safety of EUS-RFA and EUS-EA techniques. Results: In total, we identified 35 case reports and case series describing 75 patients with insulinomas treatment with EUS-guided ablation. Twenty-seven patients were treated with EUS-RFA, 47 patients with EUS-EA, and 1 patient received EUS-EA and EUS-RFA in the same session. In total, 84 insulinomas were ablated (EUS-RFA: 31, EUS-EA: 53). Most insulinomas were in the head of the pancreas (40%). The clinical success rate for EUS-guided ablation techniques was 98.5%. The median glucose level was 1.95 (Q1-Q3: 1.69–2.13) mmol/L before ablation compared to 6.20 (Q1-Q3: 5.30–7.05) mmol/L after treatment. The median insulin and C-peptide levels before and after RFA/EA were 230 (Q1–Q2: 120–257) pmol/L and 41 (Q1–Q2 35–42) pmol/L; 2077 (Q1–Q2 1644–2459) pmol/L and 819 (Q1–Q2 696–1072) pmol/L, respectively. There were eleven adverse events: seven abdominal pain, two mild acute pancreatitis, one necrotising acute pancreatitis and one local hematoma. All patients recovered, and there were no periprocedural deaths. Conclusions: EUS-guided ablation of insulinoma seems to be a safe and effective treatment and is an alternative to surgical resection in selected cases.

Abstract Introduction Conventional n-butyl-cyanoacrylate (CYA) recommended for secondary prophylaxis of gastric varices (GV) is associated with significant rebleeding and glue embolism. Limited data are available on more successful and less risky endoscopic ultrasound-guided coils and CYA (EUS-Coils-CYA) injection in GV. Methods We present a retrospective case series of 12 patients with GV bleeding managed successfully with EUS-Coils-CYA injection leading to variceal eradication in 11 patients. Results From January 2018 to June 2019, 12 cases of GV, which were either bleeding or bled recently, were included. Complete obliteration was achieved in 91.6% of patients with 100% technical success. Mean number of deployed coils and volume of injected CYA glue were 1.16 and 1.58 mL, respectively. Conclusions EUS-guided angiotherapy is an effective and safe intervention for managing GV bleeding with high technical success rate.
