Bile duct injury following laparoscopic cholecystectomy in a patient with a trifurcated hepatic duct: A case report.

INTRODUCTION AND IMPORTANCE: Iatrogenic bile duct injury is a serious complication of laparoscopic cholecystectomy, often due to misinterpretation of biliary tree anatomy. Anatomical variations, patient condition, gallbladder pathology, and surgeon-related factors are key risk factors for bile duct injury. CASE PRESENTATION: A 68-year-old male with a history of hypertension and type 2 diabetes mellitus underwent Laparoscopic cholecystectomy for symptomatic gallstones. One-month post-surgery, he developed right upper quadrant pain, jaundice, and elevated liver enzymes. Magnetic resonance cholangiopancreatography (MRCP) showed a hilar confluence stricture affecting the right posterior and left hepatic ducts, with mild-to-moderate dilation of upstream intrahepatic bile ducts. CLINICAL DISCUSSION: Trifurcation of the hepatic duct is a rare but clinically significant anatomical variation that can predispose patients to common bile duct injuries. Preoperative MRCP can identify such variations, aiding in surgical planning. However, intraoperative recognition and management of these anatomical differences are crucial to prevent bile duct injuries. This is particularly important in low-resource settings where routine preoperative imaging may not be feasible. CONCLUSION: Accurate intraoperative identification of biliary tree anatomical variations is essential to prevent iatrogenic injuries during surgery. Preoperative imaging, when available, can provide valuable information to assist in surgical planning. Additionally, the use of intra-operative cholangiogram (IOC) should be considered to help identify and manage anatomical variations, thereby reducing the risk of bile duct injuries.

Unilateral proptosis in a patient with thyroid eye disease: A case report.

Unilateral proptosis is an abnormality in which one eye sticks out forward more than the other. Bulging of the eye is commonly seen in Graves' ophthalmopathy, but it's mostly bilateral. Thyroid eye disease presents as the most common extrathyroidal manifestation of Graves' disease, and rarely leads to unilateral proptosis. A 25-year-old female with a history of weight loss, menstrual irregularities, and palpitations presented with progressive right eye bulging, which was further confirmed by magnetic resonance imaging and biochemical investigations. Magnetic resonance imaging of the orbit revealed unilateral extraocular muscle enlargement and enhancement with sparing of the tendons. Timely therapy is crucial for reversing the ocular manifestations of thyroid eye disease.
