Summary
The single-operator cholangioscopy platform (SpyGlass) shows promise for treating bile duct stones and strictures. This Brazilian case series highlights its effectiveness in complex cases.
Area of Science:
- Gastroenterology
- Therapeutic Endoscopy
Background:
- Direct endoscopic visualization of biliopancreatic ducts is a significant advancement in therapeutic endoscopy.
- The single-operator cholangioscopy platform (SpyGlass) offers a promising approach for evaluating indeterminate biliary strictures and giant choledocholithiasis.
Purpose of the Study:
- To report the first Brazilian case series on the use of the SpyGlass single-operator cholangioscopy platform.
- To evaluate the diagnostic and therapeutic utility of SpyGlass in patients with biliopancreatic duct conditions.
Main Methods:
- A case series of 20 patients undergoing SpyGlass procedures was conducted.
- Procedures included diagnostic evaluation and therapeutic interventions like electrohydraulic lithotripsy and biopsy.
Main Results:
- Choledocholithiasis was the primary indication (12/20 patients), with successful electrohydraulic lithotripsy in 87.5% of cases.
- SpyGlass aided in excluding malignancy in biliary strictures through direct visualization or biopsy.
- One complication (duodenal perforation) occurred following papillary balloon dilation.
Conclusions:
- SpyGlass is beneficial for managing large bile duct stones and indeterminate biliary strictures.
- Further prospective studies are needed to confirm potential benefits like reduced radiation exposure.

7.0K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
