Diagnosis of Ascaris lumbricoides infection using capsule endoscopy.

Ascaris lumbricoides (A. lumbricoides) is the most common intestinal roundworm parasite, infecting approximately one quarter of the world's population. Infection can lead to various complications because it can spread along the gastrointestinal tract.

Single-balloon enteroscopy for treating Roux-en-Y choledochojejunostomy stenosis after liver transplantation: a case report.

Endoscopic treatment of biliary tract complications after Roux-en-Y surgery is still a challenge. With balloon enteroscopy, we can reach previously inaccessible areas changing the management of biliopancreatic diseases in patients with surgically altered anatomy. We report a case of single-balloon enteroscopy plus endoscopic retrograde cholangiopancreatography for the treatment of a pinpoint stricture in a hepaticojejunal anastomosis after liver transplantation.
