Usefulness of argon plasma coagulation for bleeding around hepaticojejunal anastomosis

Ectopic varices due to extrahepatic portal vein obstruction (EHO) after hepaticojejunostomy have been previously reported. However, few case reports have described angiodysplasia-like lesions due to EHO around the hepaticojejunal anastomosis because they comprise small vessels in the mucosal surface and cannot be detected by contrast-enhanced computed tomography. Physicians need to insert the endoscope into the long afferent limb to diagnose angiodysplasia-like lesions around the hepaticojejunal anastomosis. Some reports have described that endoscopy stops bleeding from angiodysplasia-like lesions around the hepaticojejunal anastomosis; however, a standard methodology remains to be established. We present three cases of bleeding from an angiodysplasia-like lesion around the hepaticojejunal anastomosis that were successfully treated using argon plasma coagulation (APC) with balloon-assisted enteroscopy. Although one patient died owing to cancer progression 3 months after APC hemostasis, the hemostatic effect persisted for >2 years in the remaining two patients. These results suggest that APC is a good treatment option to stop bleeding from angiodysplasia-like lesions at hepaticojejunal anastomosis.
