"Sylvia: Based on this patient’s presentation, the most likely diagnosis is acute calculous cholecystitis, with concern for choledocholithiasis and possible ascending cholangitis (DynaMed, 2026). Her previous episodes of evening right upper quadrant and epigastric pain after heavy meals are consistent with biliary colic. However, this episode is more serious because the pain has lasted 24 hours and is now associated with fever, tachycardia, jaundice, nausea, vomiting, guarding, and rebound tenderness. Acute cholecystitis usually occurs when a gallstone obstructs the cystic duct, causing gallbladder inflammation, and it can progress to gangrene or perforation if not treated promptly (Jones et al., 2025). The jaundice is especially important because it suggests possible common bile duct obstruction, which increases the risk for ascending cholangitis (Bonomo et al., 2024).

According to DynaMed (2026), other possible diagnoses should also be considered. Choledocholithiasis is possible because jaundice may indicate obstruction of the common bile duct. Ascending cholangitis is another important concern because the combination of fever, jaundice, and right upper quadrant pain is consistent with Charcot’s triad. Gallstone pancreatitis should be ruled out because epigastric pain with nausea and vomiting can occur when a stone obstructs the ampulla; therefore, a serum lipase is important (Bonomo et al., 2024). Biliary colic explains her prior post-meal episodes, but it is less likely to explain the current episode because the pain is persistent and associated with fever and jaundice (Bonomo et al., 2024).

Diagnostic testing should begin with a complete blood count, comprehensive metabolic panel, liver function tests, total and direct bilirubin, alkaline phosphatase, lipase, serum lactate, blood cultures, a pregnancy test, coagulation studies, and a type and screen (Pagana et al., 2022). These tests help identify infection, biliary obstruction, pancreatitis, sepsis risk, pregnancy status, and readiness for possible procedures (Pagana et al., 2022). A right upper quadrant ultrasound should be ordered first because it is the preferred initial imaging test for suspected acute cholecystitis or cholangitis (Bonomo et al., 2024). Findings such as gallstones, gallbladder wall thickening, pericholecystic fluid, a sonographic Murphy sign, or common bile duct dilation would support the diagnosis. If ultrasound findings are unclear but suspicion remains high, a HIDA scan can help confirm cystic duct obstruction (Pagana et al., 2022). If labs or imaging suggest a common bile duct stone, magnetic resonance cholangiopancreatography or endoscopic ultrasound may be used for further evaluation (Bonomo et al., 2024).  Endoscopic retrograde cholangiopancreatography is appropriate when there is a high suspicion of cholangitis or persistent obstruction because it can diagnose and treat the problem by decompressing the bile duct and removing stones (Buxbaum et al., 2019).

According to Buxbaum et al. (2019), initial treatment should include hospital admission, NPO status, IV fluids, pain control, antiemetics, and broad-spectrum IV antibiotics that cover common enteric organisms. Surgical and gastroenterology consultations should be obtained early. For uncomplicated acute cholecystitis, early laparoscopic cholecystectomy during the same admission is generally preferred, ideally within the early treatment window when feasible (Mencarini et al., 2024). If cholangitis is confirmed, urgent biliary decompression with endoscopic retrograde cholangiopancreatography becomes a priority because antibiotics alone may not be enough when the duct remains obstructed (Bonomo et al., 2024).

According to Mencarini et al. (2024), patient teaching should focus on explaining that gallstones likely caused blockage and inflammation, and that jaundice, fever, worsening pain, confusion, low blood pressure, or persistent vomiting require urgent care. I would teach the patient to remain NPO until cleared, expect IV fluids, antibiotics, and possible surgery or endoscopic retrograde cholangiopancreatography, and report increasing pain, chills, dark urine, pale stools, or worsening yellowing of the skin. After recovery or surgery, teaching should include gradual diet advancement, limiting high-fat meals if they trigger symptoms, wound care if surgery is performed, medication adherence, follow-up appointments, and when to seek emergency care. Because this patient is uncomfortable and acutely ill, education should be brief initially and then reinforced with her family when she is stable.
