Endoscopic ultrasound imaging of pancreatic duct ascariasis

Abstract

Ascaris lumbricoides infestation is endemic in tropical countries. Most infections by A. lumbricoides are asymptomatic, but they can produce a wide spectrum of manifestations including hepatobiliary and pancreatic complications. Pancreatic Endoscopy_UCTN_Code_CCL_1AF_2AF_3AZ

Ascariasis imaging: pictorial essay

“…Adult worms may also obstruct the pancreatic duct, leading to pancreatitis. Acute and chronic pancreatitis has been described [54,55]. Ultrasound allows visualization of single worms, bundles of worms, or pseudotumor-like appearance [47,54,55].…”

“…Acute and chronic pancreatitis has been described [54,55]. Ultrasound allows visualization of single worms, bundles of worms, or pseudotumor-like appearance [47,54,55]. The worms can be extracted endoscopically [48] using the Sandouk maneuver [56].…”

“…Endoscopic ultrasound (EUS) has been established for a wide variety of disease [68 -77] and interventions [68,69,72,73,78]. EUS has been especially useful in the detection of pancreatic duct ascariasis and common bile duct ascariasis [54,55]. Pancreatic duct ascariasis is a rare entity.…”

“…EUS may be more sensitive for diagnosis due to high frequency probes, real-time imaging, and better visualization of the pancreas. Pancreatic ascariasis should be considered in IRAP, particularly in immigrants from developing countries [54]. Linear EUS from the stomach shows a round echogenic structure in the body of the pancreas (▶ Fig.…”

A rare etiology of idiopathic recurrent acute pancreatitis

“…Ascaris lumbricoides infestation is endemic in tropical countries. Although most infections by roundworms are asymptomatic, they can produce diverse manifestations, including hepatobiliary and pancreatic complications [1]. Ascaris is a common etiology of acute pancreatitis in developing countries.…”
