Pancreatitis Diagnosis: Normal Enzymes but Abnormal CT Scan Results - Gastroenterology and Hepatology

Understanding the complexities of pancreatitis diagnosis can be challenging, especially when laboratory tests and imaging studies yield seemingly contradictory results. In your case, the normal levels of amylase and lipase, which are enzymes typically elevated in acute pancreatitis, alongside a CT scan indicating inflammation, raise important questions.

Firstly, it is essential to understand that pancreatitis can manifest in various forms, including acute and chronic pancreatitis. Acute pancreatitis is often characterized by sudden onset abdominal pain, elevated pancreatic enzymes, and imaging findings that may show inflammation or necrosis of the pancreas. However, it is crucial to note that not all cases of pancreatitis will present with elevated enzyme levels. In some instances, particularly in early stages or milder cases, the enzyme levels may remain within normal ranges even when inflammation is present.

The CT scan results you received indicating pancreatic inflammation could suggest several possibilities. One reason for the discrepancy between normal enzyme levels and imaging findings could be the timing of the tests. If the CT scan was performed after the acute phase of pancreatitis had begun to resolve, the enzymes may have already returned to normal levels, while the inflammation could still be visible on imaging. Additionally, other factors such as the presence of chronic pancreatitis or pancreatic duct obstruction could contribute to inflammation without significant enzyme elevation.

Moreover, the symptoms you are experiencing, such as bloating, early satiety, and back pain, are indeed consistent with pancreatic issues but can also overlap with other gastrointestinal disorders, including functional gastrointestinal disorders like irritable bowel syndrome (IBS). The fact that your endoscopic evaluations (gastroscopy and colonoscopy) were normal suggests that the source of your symptoms may not be structural but rather functional.

Given that your doctor has prescribed medications to reduce intestinal motility and manage diarrhea, it indicates a consideration of functional gastrointestinal disorders as a potential cause of your symptoms. These medications can help alleviate symptoms by slowing down the movement of food through the intestines, which may provide relief from bloating and discomfort.

In summary, the presence of inflammation on the CT scan despite normal pancreatic enzyme levels can occur due to various factors, including the timing of the tests, the nature of the pancreatitis, and the possibility of overlapping gastrointestinal conditions. It is crucial to maintain open communication with your healthcare provider, who can offer further insights based on your complete clinical picture. If symptoms persist or worsen, further evaluation may be warranted, including additional imaging or consultations with specialists in gastroenterology.

Lastly, it is essential to monitor your symptoms closely and report any changes to your healthcare provider. They may consider follow-up imaging or laboratory tests if your symptoms do not improve or if new symptoms arise. Understanding the nuances of your condition will empower you to make informed decisions about your health and treatment options.
