RESUMEN
GOALS: We aimed to evaluate the ability of capsule endoscopy (CE) to detect small intestine (SI) lesions, especially SI varices, in patients with intrahepatic cirrhosis, portal hypertension (PHTN), and chronic anemia. BACKGROUND: Gastroesophageal variceal bleeding is a well-recognized complication of cirrhosis and PHTN, yet methods of identifying lesions in the SI that may contribute to covert bleeding and anemia, such as small bowel enteroscopy and angiography, are invasive and may be inadequate. STUDY: In this observational pilot study, 19 consecutive patients presenting to a tertiary care, liver transplantation referral center with cirrhosis, PHTN, and chronic anemia after obliterative esophageal variceal therapy were evaluated with wireless CE using the GIVEN Pillcam SB M2A capsule. Two independent and blinded examiners reviewed the CE examinations. RESULTS: SI varices were identified in 15.8% (3/19) of patients. Other PHTN-related findings included portal hypertensive gastropathy (13/19, 68.4%), portal hypertensive enteropathy (12/19, 63.1%), and portal hypertensive colopathy (3/19, 15.8%). Two patients had nonbleeding esophageal varices (2/19, 10.5%). A potential source of gastrointestinal blood loss was identified in 89.5% (17/19) of patients. Active bleeding sites were identified in 15.8% (3/19). CONCLUSIONS: CE can identify potential bleeding sources and could have diagnostic utility in patients with end-stage liver disease and chronic anemia after obliterative esophageal variceal therapy.

Endoscopic retrograde cholangiopancreatography (ERCP) is a useful tool in the evaluation and management of acute pancreatitis. This review will focus on the role of ERCP in specific causes of acute pancreatitis, including microlithiasis and gallstone disease, pancreas divisum, Sphincter of Oddi dysfunction, tumors of the pancreaticobiliary tract, pancreatic pseudocysts, and pancreatic duct injury. Indications for endoscopic techniques such as biliary and pancreatic sphincterotomy, stenting, stricture dilation, treatment of duct leaks, drainage of fluid collections and stone extraction will also be discussed in this review. With the advent of less invasive and safer diagnostic modalities including endoscopic ultrasound (EUS) and magnetic retrograde cholangiopancreatography (MRCP), ERCP is appropriately becoming a therapeutic rather than diagnostic tool in the management of acute pancreatitis and its complications.
