BMJ Case Rep 2025;18:e268480 . doi:10 . 1136/bcr-2025- 268480  \nSUMMARY  \nA man in his 50s sustained a Strasberg type D bile duct injury during laparoscopic cholecystectomy, which was initially misdiagnosed as a minor bile leak. Upon referral, he presented with abdominal pain, sepsis and a large biloma. Endoscopic retrograde cholangiopancreatography (ERCP) with plastic stent placement and percutaneous drainage resolved the leak, but a severe stricture of the common hepatic duct persisted. A biodegradable polydioxanone-based biliarystent was subsequently deployed, resulting in complete stricture resolution and improved ductal patency at 6-month follow-up, with no complications. This case illustrates the potential role of biodegradable stents in managing complex biliary injuries.  \nBACKGROUND  \nBiliary tract injuries are a recognised complication of laparoscopic cholecystectomy and may result in bile leaks, strictures or fistula formation if not promptly diagnosed and treated. Strasberg type D injuries, which involve the common hepatic duct, usually require surgical reconstruction. However, in the presence of sepsis or significant inflammation, surgical intervention may pose substantial risks.  \nRecent developments in biodegradable biliarystents offer a novel, minimally invasive alternative by providing temporary ductal support without the need for later removal. These stents may reduce the frequency of interventions and associated complications. This case report describes the first documented endoscopic use of a biodegradable biliarystent for a complex bile duct injury in Saudi Arabia and evaluates its short-term outcomes.  \nCASE PRESENTATION  \nA man in his 50s with a medical history of hypertension underwent laparoscopic cholecystectomy. He was initially diagnosed with a minor bile leak but re-presented 1 week later with persistent right upper quadrant pain and low-grade fever. MRI identified a large fluid collection (biloma) and an abrupt ductal cut-off at the level of the hepatic duct. The patient was initially treated conservatively with an ultrasound-guided pigtail drainage of the localised biloma, which was removed before his discharge. He was referred to our tertiary care unit, where he was febrile and exhibited clinical signs of early sepsis for further evaluation and management.  \nINVESTIGATIONS  \nThe initial laboratory evaluation demonstrated a predominantly cholestatic pattern of liver injury, with markedly elevated alkaline phosphatase (303 U/L) and γ-glutamyl transferase (504 U/L), accompanied by moderate elevations in transaminases (aspartate aminotransferase (AST) 94 U/L, alanine aminotransferase (ALT) 191 U/L) and a mild rise in total and direct bilirubin (1.99 mg/dLand 0.62 mg/dL, respectively). Notably, the C-reactive protein (CRP) level was markedly elevated at 288.9 mg/L, and procalcitonin 2.6 ng/mL, indicating a significant inflammatory response and early sepsis. The MRI demonstrated a post-cholecystectomy large operative bed collectio","cbCaivFggn278izd","https://ap.wps.com/l/cbCaivFggn278izd","pdf",413158,"English","# Summary\n# Background\n# Case presentation\n# Investigations\n# Differential diagnosis\n# Treatment","[{\"question\":\"What injury and initial misdiagnosis occurred after laparoscopic cholecystectomy?\",\"answer\":\"A man sustained a Strasberg type D bile duct injury, initially misdiagnosed as a minor bile leak.
