Histopathological study on inflammation in cholecystoses
Insights
Cholecystoses, often considered non-inflammatory, frequently involve inflammation and gallstones. This study suggests reconsidering their classification due to these common associations.
Area of Science:
- Gastroenterology
- Pathology
- Surgical Pathology
Background:
- Cholecystoses are traditionally defined as non-inflammatory, non-gallstone gallbladder diseases.
- Clinical observations suggest inflammation and gallstones may be more prevalent in cholecystoses than currently accepted.
- This challenges the established classification and understanding of these gallbladder conditions.
Purpose of the Study:
- To investigate the actual prevalence of inflammation and lithiasis in surgically removed gallbladder specimens diagnosed as cholecystoses.
- To histopathologically re-evaluate the classification of cholecystoses based on the presence of inflammatory processes and gallstones.
- To correlate histopathological findings with clinical data regarding disease evolution.
Main Methods:
- Histopathological examination of 1,630 surgically removed gallbladder specimens.
- Identification and classification of cholecystoses, including cholesterolosis and diverticular disease.
- Assessment for the presence of inflammatory processes and lithiasis within the gallbladder specimens.
Main Results:
- 278 cases (17.05%) were identified as cholecystoses (156 cholesteroloses, 122 diverticular diseases).
- Inflammation was present in 80.21% of cholecystosis cases (66.67% of cholesteroloses, 97.54% of diverticular diseases).
- Gallstones (lithiasis) were found in 46.76% of cholecystosis cases, with inflammation correlating to approximately three years of clinical disease evolution.
Conclusions:
- The findings strongly suggest that inflammation is a common feature of cholecystoses, contrary to traditional definitions.
- The frequent association with lithiasis further supports the need to reconsider the classification of cholecystoses.
- The scope of chronic non-inflammatory, non-lithiasic gallbladder diseases is significantly narrower than previously understood.
Abstract:
At present, according to the unanimously accepted data, cholecystoses are noninflammatory, nonlithiasic, gallbladder diseases. However the authors' experience has proved that the inflammatory process is much more frequent than it is believed and often associated also with lithiasis, a fact which, in the authors' opinion, would justify a reconsideration of this group of diseases. This study, based on histopathologic examination, was carried out in 1,630 gallbladder specimens, surgically removed. Out of these, 278 (17.05 per cent) were identified as cholecystoses; 156 out of them were cholesteroloses and 122 diverticular diseases of the gallbladder. Inflammation as a well defined morphologic process was found in 104 cases (66.67 per cent) of cholesterolosis and in 119 cases (97.54 per cent) of diverticular disease, therefore 80.21 per cent of the cases of cholecystosis examined were associated with inflammation. As regards lithiasis, it was present in 131 of the cases (46.76 per cent). The inflammatory process presented a chronic aspect with no other particular morphologic characteristics. By correlating the histopathologic data with the clinical evolutive ones, it was observed that the presence of inflammation corresponded with a clinical evolution of the disease of about three years. The authors believed that the group of cholecystoses should be reconsidered bearing in mind that inflammation is present in most of the cases and in almost half of them it is associated with lithiases. Under these conditions the sphere of chronic nonlithiasic, noninflammatory gallbladder diseases becomes considerably reduced today.
