MSN 5600 Diagnosis, Symptom and Illness Management Gallbladder and Common Duct Stones Case Study The patient, a 44-year-old mother of seven children, was an obese woman. Two weeks before she was admitted to the hospital, she began to complain of right upper quadrant abdominal pain associated with nausea and vomiting. Two days before admission, she noticed that her urine was very dark and her stools were lighter in color. The results of her physical examination revealed she was mildly icteric. Her abdominal examination results indicated mild upper abdominal tenderness and muscle guarding.

No other abnormalities were noted during her physical examination. Studies Results Complete blood cell count (CBC), electrolyte, glucose, and blood urea nitrogen (BUN) determinations Normal Total serum bilirubin determination 3.8 mg/dL (normal: 0.1-1.0 mg/dL) — Indirect fraction 1.0 mg/dL (normal: 0.2-0.8 mg/dL) — Direct fraction 2.8 mg/dL (normal: 0.1-0.3 mg/dL) Urine bilirubin test +3 (normal: negative) Liver enzymes test — Serum aspartate aminotransferase (AST) 46 International units/L (normal: 5-40 International units/L) — Serum alanine aminotransferase (ALT) 40 International units/L (normal: 5-35 International units/L) — Lactic dehydrogenase (LDH) 228 units/L (normal: 90-200 units/L) — Alkaline phosphatase (ALP) 885 units/L (normal: 30-85 units/L) — 5′-Nucleotidase 2.4 units (normal: 0-1.6 units) — Leucine aminopeptidase (LAP) 250 units/mL (normal: 75-185 units/mL) — Serum gamma-glutamyl transpeptidase (GGTP) 250 units/L (normal: 5-27 units/L) — Total serum protein test 7.2 g/dL (normal: 6-8 g/dL) — Serum albumin test 4.2 g/dL (normal: 3.2-4.5 g/dL) — Prothrombin time (PT) test 14.2 seconds (patient); 12.0 seconds (control).

Ultrasound examination of the liver and gallbladder showed dilated intrahepatic and extrahepatic bile ducts with stones within the gallbladder. Endoscopic retrograde cholangiopancreatography (ERCP) indicated a dilated common bile duct containing a gallstone. Diagnostic analysis suggested obstructive jaundice due to increased levels of direct bilirubin, alkaline phosphatase, 5′-nucleotidase, GGTP, and LAP, along with minimally elevated AST and LDH. Urine bilirubin corroborated the clinical finding of direct hyperbilirubinemia. The prolonged PT was attributed to impaired vitamin K absorption and hepatic synthesis of clotting factors. Imaging confirmed gallstones causing common bile duct obstruction, with ERCP confirming a gallstone as the obstruction source. The patient underwent sphincterotomy (papillotomy) of the ampulla of Vater, and the stones were removed. Subsequently, she had a laparoscopic cholecystectomy, with an uneventful postoperative course. Her bilirubin levels normalized, and she resumed normal activities within 5 days.

The case study of a 44-year-old woman presenting with symptoms of biliary obstruction provides valuable insight into the diagnosis and management of gallstone-related diseases, particularly choledocholithiasis. Her presentation with right upper quadrant pain, dark urine, light stools, and jaundice are characteristic features of obstructive jaundice resulting from gallstones lodged within the common bile duct. This condition often involves a complex interplay between anatomical, pathological, and biochemical factors that require a thorough understanding for effective diagnosis and treatment.

Obstructive jaundice occurs when a blockage in the biliary system impairs the flow of bile from the liver to the intestine. The clinical presentation often includes right upper quadrant pain, which is colicky or persistent, nausea, vomiting, and signs of jaundice such as dark urine and pale stools. The patient's physical examination revealing mild icterus and upper abdominal tenderness aligns with such a diagnosis. Laboratory data further support this, with elevated direct bilirubin, alkaline phosphatase, gamma-glutamyl transpeptidase (GGT), and other liver enzymes, indicating cholestasis or biliary obstruction.

The biochemical profile highlights the key aspects of obstructive jaundice. Total serum bilirubin in this patient was significantly elevated at 3.8 mg/dL, predominantly of the direct (conjugated) form, which points towards impaired excretion of conjugated bilirubin into the bile ducts. The urine bilirubin test being positive reinforces the diagnosis of conjugated hyperbilirubinemia, as conjugated bilirubin is water-soluble and excreted in urine when levels are high. Biochemically, elevated alkaline phosphatase, GGT, 5'-nucleotidase, and LAP serve as markers of cholestasis, as these enzymes are elevated when bile flow is hindered (Karim et al., 2018).

Imaging studies like ultrasonography and ERCP are indispensable in confirming the diagnosis. The ultrasound revealing dilated intrahepatic and extrahepatic bile ducts with gallstones strongly suggests gallstone-induced obstruction. ERCP serves both diagnostic and therapeutic purposes, allowing direct visualization and removal of stones within the common bile duct, as performed in this case. The sphincterotomy of the ampulla of Vater facilitates stone extraction and alleviates biliary obstruction, which is essential in preventing complications such as cholangitis and biliary cirrhosis (Gorrepati et al., 2020).

From a pathophysiological perspective, the obstruction leads to the backup of conjugated bilirubin into the bloodstream, resulting in jaundice. The impairment of enterohepatic circulation reduces absorption of vitamin K, causing a deficit of clotting factors and prolonging prothrombin time, which was observed in this patient. This emphasizes the importance of monitoring coagulation status and considering vitamin K supplementation perioperatively (Lau et al., 2019).

Following stone removal, laparoscopic cholecystectomy addresses the root cause by removing the gallbladder harboring stones, reducing the likelihood of recurrence. The patient's uneventful recovery and normalization of bilirubin levels indicate successful intervention. Postoperative monitoring includes liver function tests and assessment for potential complications such as biliary leak or infection. Education on lifestyle modifications, including weight management and diet, are integral to preventing future gallstone formation (Sutaria & Khurana, 2021).

In conclusion, this case highlights the importance of a multidisciplinary approach combining clinical assessment, laboratory investigations, and advanced imaging techniques to diagnose biliary diseases. Timely intervention with minimally invasive procedures such as ERCP and cholecystectomy effectively resolves obstruction and prevents complications. Understanding the biochemical and physiological basis of these conditions is vital for clinicians to optimize patient outcomes.
