Study
  • Condition: Jaundice
  • Journal: Surgical endoscopy
  • Treatment Used: Endoscopic Ultrasound-Guided Choledochoduodenostomy (CDD)
  • Number of Patients: 284
  • Published —
This study evaluated the effectiveness and safety of endoscopic ultrasound-guided choledochoduodenostomy (method of biliary drainage; CDD) using lumen-apposing metal stents (LAMS) in patients with jaundice (yellowing of the skin and the whites of eyes that happens when the body does not process bilirubin properly) who failed conventional endoscopic retrograde cholangiopancreatography (procedure used to diagnose diseases of the gallbladder, biliary system, pancreas, and liver; ERCP).
Latest Advance
Study
  • Condition: Pancreatic Walled-Off Necrosis (WON)
  • Journal: Endoscopy
  • Treatment Used: Endoscopic Ultrasound (EUS)-Guided Placement of Lumen-Apposing 15mm Metal Stent (LAMs) vs. Endoscopic Ultrasound (EUS)-Guided Placement of Lumen-Apposing 20mm Metal Stent (LAMs)
  • Number of Patients: 306
  • Published —
This review of available literature considered patients with pancreatic walled-off necrosis (isolated collection of pus in the pancreas and dead tissue secondary to infection and inflammation of the pancreas; WON) in order to evaluate the effectiveness of treatment via either endoscopic ultrasound (minimally invasive procedure allowing viewing of the digestive tract; EUS)-guided placement of lumen-apposing 15mm metal stent (small, barbell-shaped, metal tube designed to be inserted to drain fluid in the pancreas; LAMs) versus endoscopic ultrasound (EUS)-guided placement of lumen-apposing 20mm metal stent (LAMs).
Latest Advance
Study
  • Condition: Ampullary Adenoma
  • Journal: Digestive diseases and sciences
  • Treatment Used: Endoscopic Papillectomy
  • Number of Patients: 161
  • Published —
In this study, researchers evaluated the long-term results of having an endoscopic papillectomy for ampullary adenomas.
Latest Advance
Study
  • Condition: High Risk Surgical Patients with Acute Cholecystitis
  • Journal: Endoscopy
  • Treatment Used: Endoscopic Ultrasound-Guided Gallbladder Drainage (EUS-GBD) vs. Percutaneous Cholecystostomy
  • Number of Patients: 495
  • Published —
This review of the literature compared endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) versus percutaneous gallbladder drainage in high risk surgical patients with acute cholecystitis (gallbladder inflammation).
Latest Advance
Study
  • Condition: Distal Malignant Biliary Obstruction
  • Journal: Digestive diseases and sciences
  • Treatment Used: EUS-Guided Choledochoduodenostomy (EUS-CD) Using Electrocautery-Enhanced Lumen-Apposing Metal Stents (LAMS)
  • Number of Patients: 67
  • Published —
This study evaluated the effectiveness of EUS-guided choledochoduodenostomy (used or gallbladder, bile ducts, or bile drainage; EUS-CD) using electrocautery-enhanced (electrically heated) lumen-apposing metal stents (tool to facilitate potentially safer and easier endoscopic drainage; LAMS) for distal malignant biliary obstruction (blockage of the bile ducts).
Latest Advance
Study
  • Condition: Peripancreatic Fluid Collections
  • Journal: Endoscopy
  • Treatment Used: Lumen-Apposing Metal Stents (LAMSs)
  • Number of Patients: 62
  • Published —
This study evaluated the outcomes (technical success, clinical success, rate/severity of adverse events, length of stay, recurrence) of the use of lumen-apposing metal stents (LAMSs) for the drainage of postoperative fluid collections (POFCs).
Latest Advance
Study
  • Condition: Acute Cholecystitis
  • Journal: Gastrointestinal endoscopy
  • Treatment Used: EUS-Guided Drainage with Lumen-Apposing Metal Stent vs Endoscopic Transpapillary Gallbladder Drainage (GB)
  • Number of Patients: 78
  • Published —
This study compared the outcomes of EUS-guided gallbladder drainage with a lumen-apposing metal stent versus endoscopic transpapillary gallbladder drainage (GD) for the treatment of acute cholecystitis (inflammation of the gallbladder).
Latest Advance
Study
  • Condition: Infected vs. Symptomatic Sterile Walled-Off Pancreatic Necrosis (WON)
  • Journal: Gut and liver
  • Treatment Used: Minimally Invasive Therapy
  • Number of Patients: 211
  • Published —
This study compared outcomes of infected to symptomatic sterile acute pancreatitis complicated by walled-off necrosis (WON) in patients who were undergoing dual-modality drainage as minimally invasive therapy.
Latest Advance
Study
  • Condition: Roux-en-Y gastric bypass anatomy
  • Journal: Gastrointestinal endoscopy
  • Treatment Used: EUS-guided gastrogastrostomy-assisted ERCP versus enteroscopy-assisted ERCP
  • Number of Patients: 60
  • Published —
This study compared outcomes and adverse events between EUS-guided gastrogastromy-assisted ERCP versus enteroscopy-assisted ERCP in patients with Roux-en-Y gastric bypass anatomy.
Latest Advance
Study
  • Condition: Walled-Off Pancreatic Necrosis (WON)
  • Journal: Journal of gastroenterology and hepatology
  • Treatment Used: Dual-Modality Drainage (DMD) Combined with Short Duration of Antibiotics (SD) vs. Dual-Modality Drainage (DMD) Combined with a Long Duration of Antibiotics (LD)
  • Number of Patients: 61
  • Published —
This review of available literature considered patients with walled-off pancreatic necrosis (isolated collection of pus in the pancreas and dead tissue secondary to infection and inflammation of the pancreas; WON) in order to evaluate the effectiveness of dual-modality drainage (minimally invasive drainage technique; DMD) combined with a short duration of antibiotics (SD) versus dual-modality drainage combined a long duration of antibiotics (LD).
