BACKGROUND/AIMS The objective of our study was to identify useful computed tomography (CT) findings for differentiating fundal type adenomyomatosis from localized chronic cholecystitis involving the fundus of the gallbladder. METHODS We retrospectively identified cases of 41 patients with pathologically proven adenomyomatosis (n=21) or chronic cholecystitis (n=20) who had fundal thickening of...

Acalculous cholecystitis is a rare but life-threatening disease, but its pathogenesis is not fully revealed yet. We experienced two acalculous cholecystitis cases associated with aortic dissection. In Case 1, acalculous cholecystitis occurred just after the exacerbation of the aortic dissection. Laparotomy showed necrotized cholecystitis with fresh thrombi formation. Case 2 developed acalculous...

We report a case of bile fistula after cholecystectomy in a patient with severe right liver atrophy, which was managed by endoscopic nasobiliary drainage and conservative treatment. The patient was a 76-year-old man with a sudden onset in the right flank and abdominal pain. Computed tomography revealed calculous cholecystitis and severely atrophied right lobe of the liver. Gallbladder was locat...

Intrauterine device (IUD) is a popular long-acting reversible contraceptive device with an estimated rate of use of about 5.3%. It is highly effective but not without complications, one of which is uterine perforation. The patient was a 32-year-old female who presented with nausea, vomiting and right upper quadrant abdominal pain that was tender on palpation. CT scan was performed and they foun...

We investigated the distribution of myofibroblasts and CD34-positive stromal cells in normal gallbladder and its pathological conditions (cholecystitis, n=25) using immunohistochemistry and in situ hybridization. In the wall of normal gallbladder, myofibroblasts were generally absent from all layers, but many CD34-positive stromal cells were observed in the connective tissue layer. In chronic c...

Gallstone ileus is a rare cause of bowel obstruction and abdominal x-ray can identify small bowel obstruction, pneumobilia, and ectopic gallstone (Rigler’s triad) in less than 30% of the patients. We present herein the case of an 80-year-old woman diagnosed 4 years prior with chronic calculous cholecystitis that was untreated. Physical examination and clinical anamnesis were consistent with bow...

Objective: Case report of biliary tract lesion caused by the presence of a foreign body into the abdominal cavity after cholecystectomy. Case report: A 56-year-old woman reported postprandial fullness, nausea, vomiting, hyperexia, weight loss, pain and palpable mass in right hypochondrium for 15 months, three months after she had been submitted to cholecystectomy due to chronic calculous cholec...
