Adenomyomatosis (AMM) is related to the group of hyperplastic cholecystosis. Despite a long history of studying the problem, many questions concerning the etiology, pathogenesis, prevalence, tactics, management and treatment remain unsolved.
Objective: To set the frequency of the AMM, its types, nature of pathological changes in the wall and lumen of gallbladder on the base of analizing the gallbladders after surgical removal.
Material and methods: ultrasound examination, macro--and microscopic evaluation of 328 cases of the AMM gallbladders.
Results: According to ultrasound examination detection rate of AMM was 16.6%, and aacording to the study of surgical material--33%. The average age of patients 53 years old, male to female ratio--1:3,7. In 193 cases, the AMM was combined with concrements in gallbladder, in 70 cases the AMM was combined with polyps, among them in 40 patients the polyps were combined with concrements. In 175 patients we visualy analyzed the compaund of stones in gallbladder, in 112 cases there were the cholesterol stones (64%), in 51 cases--pigment stones (29.1%), in 12 patients (6.9%)--mixed. In some cases, was mentioned a combination of different AMM forms: adenomyoma on the background of diffuse adenomiomatosis--3.3%, diffuse form of AMM with more emphasized segmental lesions in one of the parts of gallbladder--6.1%, adenomyoma in one part combined with segmental lesions of another part of the gallbladder in 1.2% cases. In 64.9% cases, the AMM was combined with lipomatosis, in 56.7% cases--with the cholesterosis.
Conclusion: The AMM is not a rare disease of gallbladder, and according to the histological examination of surgical material is detected in 31% of cases, and is oftenly combined with other types of hyperplastic cholecystosis.
