Gallstone ileus is an unusual cause of colonic obstruction. The formation of a fistula between the gall bladder and the bowel wall may allow a gallstone to enter the intestinal tract. Plain abdominal films, abdominal ultrasound and abdominal computed tomography aid in the diagnosis. Although surgery is the treatment of choice in cases of colonic gallstone ileus, colonoscopic removal of the impa...

We report a case of a 92-year-old man complaining of epigastric pain, which an US first and a CT scan later revealed to be related to a large gallstone causing cholecystitis. After the patient had refused surgical treatment for this condition, he was again referred to our Emergency Department presenting with a clinical picture of gastric obstruction. A new CT scan showed the classic Rigler’s tr...

Cholesterol gallstone disease is highly prevalent in western countries, particularly in women and some specific ethnic groups. The formation of water-insoluble cholesterol crystals is due to a misbalance between the three major lipids present in the bile: cholesterol, bile salts, and phospholipids. Many proteins implicated in biliary lipid secretion in the liver are regulated by several transcr...

Gallstone ileus is a rare mechanical bowel obstruction, and previously reported cases have been treated laparoscopically with good results. Although transvaginal hybrid NOTES without a minilaparotomy has been reported to decrease the incidence of surgical wound complications, to our knowledge, this procedure has not been used previously to treat gallstone ileus. We present a case of a 63-year-o...

Gallstone ileus is a rare but potentially serious complication of cholelithiasis. It is usually preceded by history of biliary symptoms. It usually occurs as a result of a large gallstone creating and passing through a cholecysto-enteric fistula. Most of the time, the stone will pass the GI tract without any problems, but large enough stones can cause obstruction. The two most common locations ...

Obstruction at the level of the gastric outlet by a gallstone is defined as Bouveret's syndrome. It is an uncommon form of gallstone ileus. A single gallstone of at least 2.5 cm in diameter is the most common underlying cause of Bouveret's syndrome. Diagnosis is based on the clinical manifestations, existence of pneumobilia, visualization of lithiasis and demonstration of duodenal obstruction. ...

A 57-year-old woman was admitted to our hospital with abdominal pain and vomiting. Her abdomen was distended, and obstructive bowel sounds were discovered on examination. Diffuse abdominal tenderness was present, but no palpable masses were apparent. Abdominal computed tomography confirmed a large gallstone obstructing the small bowel. Colonoscopy revealed a large gallstone lodged at the termin...

background: the method of proton induced x-ray emission (pixe) has been widely used as a sensitive technique to trace elemental analysis in both biological and medical fields. the sensitivity of this powerful method is in the order of ppm .the aim of this work is to analyze structural composition of 4 heavy trace elements with z greater than 24 (mn, fe, cu, zn) in two kinds of gallstones and to...

We report the case of a 94-year-old woman with Bouveret's syndrome, where endoscopic treatment was performed. Bouveret’s syndrome is a gastric outlet obstruction due to gallstone impaction within the duodenum. It is the least frequent presentation of gallstone ileus. Gallstone ileus is a complication of cholelithiasis and has a high morbidity and mortality. Therefore, it requires an early diagn...
