Cholecystokinin (CCK), a gastrointestinal hormone, is secreted by the duodenum in response to the presence of gastric acid, amino acids and nutrients in particular fat in the duodenal lumen (1). The half life of this hormone is about 2.5 minutes and the kidney is considered the major site of its uptake from the systemic circulation. Cholecystokinin is responsible for stimulating gallbladder con...

Strangulation of the gallbladder associated with the omentum is extremely rare and, to our knowledge, only two cases have been previously reported. The patient was a 91-year-old female who presented to our emergency room with a chief complaint of upper abdominal pain. Computed tomography imaging revealed a gourd-shaped gallbladder with biphasic appearance divided clearly at the body. In the fun...

squamous cell carcinoma of the gallbladder is rare and constitutes only 0.5-3% of all malignancies of this organ. most of the reported cases have had a component of adenocarcinoma. we report a 70-year-old man who presented with acute onset right upper quadrant pain. he operated on based on a presumptive diagnosis of acute cholecystitis according to clinical and ultrasonographic findings. histop...

Gallbladder rupture following blunt abdominal trauma is a rare event recognized on evaluation and treatment of other visceral injuries during laparotomy. Isolated gallbladder rupture secondary to blunt abdominal trauma is even more uncommon. The clinical presentation of gallbladder injury is variable, resulting in a delay in diagnosis and treatment. We report the case of a patient who suffered ...

Gallbladder torsion is a rare entity. Recently, laparoscopic cholecystectomy has become accepted as a standard operation for gallbladder torsion. Unfortunately, kyphoscoliosis is a risk factor of gallbladder torsion, and kyphoscoliosis results in a low-lying costal arch and disturbs the laparoscopic view. The present paper reports a new surgical procedure, a "rib-lifting method" for retracting ...

Tuberculosis of gallbladder is an extremely rare entity even in endemic region. Pre-operative diagnosis may not be possible and most of the cases are found incidentally during histopathological examination of resected specimen of gallbladder. We are presenting a case of tuberculosis of gallbladder presenting as acalculous cholecystitis in a middle aged female patient. We conclude that each gall...

Ciliated foregut cyst of gallbladder is a very rare benign cystic lesion. A 39-year-old woman was referred to our hospital after abdominal ultrasonography revealed a cystic lesion of gallbladder. On abdominal ultrasonography and computed tomography, a unilocular cystic lesion was found at right upper quadrant with attachment to the gallbladder neck. The gallbladder with cystic lesion was resect...

Gallbladder perforation is an almost exclusive complication of cholecystitis, which accompanies severe inflammation of the gallbladder with or without cholelithiasis. Whether it is of a calculous or acalculous origin, gallbladder perforation, as a complication of acute cholecystitis, has common symptoms, signs, laboratory data, radiological findings and treatment modalities. Even though many re...

Torsion of the gallbladder is a rare entity that is difficult to diagnose preoperatively. The condition occurs most often in the elderly. Although its etiology is unknown, a constant finding is the presence of the gallbladder on a mobile mesentery (floating gallbladder). Torsion, or volvulus, of the gallbladder occurs when it twists axially, with the subsequent occlusion of bile and/or blood fl...

Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preo...
