Serial computed tomography scanning in acute pancreatitis: a prospective study.

Area of Science:

• Medical Imaging
• Gastroenterology
• Radiology

Background:

• Acute pancreatitis is a significant medical condition requiring accurate diagnosis and monitoring.
• Computed tomography (CT) is a key imaging modality in evaluating abdominal pathologies.

Purpose of the Study:

• To assess the utility of serial abdominal CT scans in evaluating acute pancreatitis.
• To correlate CT findings with clinical severity and outcomes.
• To evaluate the detection and characterization of pancreatic pseudocysts using CT.

Main Methods:

• One hundred and two patients with acute pancreatitis underwent abdominal CT scans at admission, one week, and six weeks.
• CT findings were analyzed for abnormalities, etiology, pancreatic size, and pseudocyst detection.
• Statistical analysis was performed to compare CT parameters between mild and severe attacks and apparent vs. non-apparent pseudocysts.

Main Results:

• Abnormalities were frequent on CT scans (91% admission, 84% one week, 51% six weeks).
• CT identified etiology in 27% of cases, with specific sensitivities and specificities for fatty liver and gallstones.
• Pancreatic size indices were significantly larger in severe attacks compared to mild attacks (p < 0.004).
• Fourteen pseudocysts were detected; larger pseudocysts (size index ≥ 15 cm²) were more likely to be clinically apparent and require treatment (p < 0.01).

Conclusions:

• Serial CT scans are valuable for monitoring acute pancreatitis, detecting complications, and assessing severity.
• CT findings, particularly pancreatic size, correlate with clinical severity.
• CT is effective in detecting and characterizing pancreatic pseudocysts, guiding treatment decisions.
