Obstructive jaundice with a biliary clot post-endoscopic sphincterotomy treated with clipping and endoscopic biliary stenting

A 62-year-old man was admitted with epigastralgia. He had a history of laparoscopic cholecystectomy for cholecystolithiasis. He had no coagulopathy and was not taking anticoagulants. Abdominal computed tomography (CT) showed a common bile duct (CBD) stone ([Fig. 1 a]). Endoscopic retrograde cholangiography (ERC) and intraductal ultrasonography (IDUS) also showed a 2.8-mm CBD stone ([Fig. 1 b, ] [Fig. 2 a, b]). Endoscopic sphincterotomy (EST) was performed ([Fig. 2 c]) and the CBD stone was removed using a wire basket ([Fig. 2 d]).

The patient complained of epigastralgia again after 4 days. Laboratory investigations demonstrated elevated cholestatic parameters: total bilirubin 2.8 mg/dL (normal range 0.4 – 1.5 mg/dL), aspartate aminotransferase 176 U/L (13 – 30 U/L), alanine aminotransferase 146 U/L (10 – 42 U/L), alkaline phosphatase 233 U/L (38 – 113 U/L), and gamma-glutamyl transpeptidase 695 U/L (9 – 32 U/L); hemoglobin was within the normal limit. CT showed a diffuse high-density structure in the CBD, with the bile duct mildly dilated ([Fig. 3 a]). ERC revealed post-EST bleeding and a biliary clot in the CBD ([Fig. 3 b, ] [Fig. 4 a]). The clot was removed using a grasping forceps and wire basket ([Fig. 3 c], [Fig. 4 b]), and an endoscopic biliary stent (EBS) was inserted into the CBD for biliary drainage. Clipping was applied to stop the bleeding ([Fig. 3 d], [Fig. 4 c, d, ] [Video 1]). The patient progressed well after the procedures. The EBS was removed 8 days postoperatively and the patient was discharged 10 days postoperatively.

The incidence of post-EST delayed hemorrhage is 1.62 % [1], and biliary obstruction with a biliary clot caused by post-EST bleeding is extremely rare [2] [3] [4] [5]. Endoscopic hemostasis is currently the first treatment choice for post-ERC bleeding, with balloon dilation and biliary stent placement used for treatment [2] [3] [4] [5]. To the best of our knowledge, this is the first English case report of obstructive jaundice with a biliary clot caused by post-EST bleeding, treated with clipping and an EBS, which may be an effective endoscopic technique for treating such cases.
