Bouveret＇s syndrome complicated by a distal gallstone ileus

AIM: Gastric outlet obstruction caused by duodenal impaction of a large gallstone migrated through a cholecystoduodenal fistula has been referred as Bouveret‘s syndrome. Endoscopic lithotomy is the first-step treatment, however, surgery is indicated in case of failure or complication during this procedure .METHODS: We report herein an 84-year-old woman presenting with features of gastric outlet obstruction due to impacted gallstone. She underwent an endoscopic retrieval which was unsuccessful and was further complicated by distal gallstone ileus. Physical examination was irrelevant. RESULTS: Endoscopy revealed multiple erosions around the cardia, a large stone in the second part of the duodenum causing complete obstruction, and wide ulceration in the duodenal wall where the stone was impacted. Several attempts of endoscopic extraction by using foreign body forceps failed and surgical intervention was mandatory. Preoperative ultrasound evidenced pneumobilia whilst computerized tomography showed a large stone, 5cm×4cm×3cm, logging at the proximal jejunum and another one, 2.5cm×2cm×2cm, in the duodenal bulb causing a closed-loop syndrome. She underwent laparotomy and the jejunal stone was removed by enterotomy. Another stone reported as located in the duodenum preoperatively was found to be present in the gallbladder by intraoperative ultrasound. Therefore, cholecystoduodenal fistula was broken down, the stone was retrieved and cholecystectomy with duodenal repair was carried out. She was discharged after an uneventful postoperative course. CONCLUSION: As the simplest and the least morbid procedure, endoscopic stone retrieval should be attempted in the treatment of patients with Bouveret‘s syndrome. When it fails, surgical lithotomy consisting of simple enterotomy may solve me problem. Albhough cholecystectomy and cholecystoduodenal fistula breakdown is unnecessary in every case, conditions may urge the surgeon to perform such operations even though they carry high morbidity andmortality.     

Bouveret’s syndrome with a concomitant incidental T1 gallbladder cancer

Bouveret’s syndrome, which is a gastric outlet obstruction caused by a gallstone in the duodenum, is a rare complication of gallstone disease. We report a case of Bouveret’s syndrome in an 81-year-old woman who also exhibited incidental gallbladder cancer. She was admitted to our hospital complaining of upper abdominal pain and vomiting. A computed tomography examination showed a cholecystoduodenal fistula, a large impacted stone at the gastric outlet, and a dilated stomach. She was diagnosed as having Bouveret’s syndrome. The patient underwent an upper gastrointestinal endoscopy and a mechanical lithotripsy was successfully performed for the stone. She then underwent a cholecystectomy with primary closure of the duodenal fistula. An intra-operative histopathology examination revealed severe cholecystitis with an adenocarcinoma in part of the gallbladder. Gallbladder bed resection and regional lymph node dissection were also performed. To the best of our knowledge, this is the first published report of a case in which Bouveret’s syndrome and gallbladder cancer co-existed.     

Bouveret's syndrome: the clinical and radiological findings]

Bouveret's syndrome is an unusual presentation of gallstone ileus, due to duodenal obstruction. It is produced by the migration of biliary calculus through a cholecystogastric or cholecystoduodenal fistula. We present 3 new cases of Bouveret's syndrome, and the clinical and radiological findings on different imaging procedures (plain abdominal radiography, barium studies, ultrasonography and computed tomography). On the basis of these cases, we discuss the diagnostic and possibly therapeutic merits of digestive endoscopy and about the different surgical procedures.     

Another new variant of Bouveret's syndrome

Although Bouveret's syndrome, i.e. gastric outlet obstruction by a large gallstone impacted in the proximal duodenum secondary to a cholecystoduodenal fistula,is rare, its pathogenesis and clinical features are well characterized. However, existence of variant forms of the syndrome are not well known, and as far as we have been described in the English-language literature.We present a case of another new variant of Bouveret's syndrome in a 54-year-old Korean woman.     

Bouveret's syndrome--an unusual cause of spontaneous resolution of gastric outlet obstruction.

Gastric outlet obstruction due to a gallstone impacted in the duodenal bulb (Bouveret's syndrome) is a rare complication of gallstones. We report a 47-year-old man with this syndrome in whom the impacted stone migrated uneventfully.     

Shock-wave therapy of gastric outlet syndrome caused by a gallstone

A patient with gastric outlet syndrome (Bouveret's syndrome) caused by a large gallstone impacted in the duodenal bulb was successfully treated by extracorporeal shock-wave lithotripsy. Thus, open abdominal surgery could be avoided. For disintegration of the stone, three consecutive lithotripsy procedures were necessary. Thereafter, stone fragments could be extracted endoscopically. Extracorporeal shock-wave lithotripsy could become a non-surgical alternative in patients with obstruction of the duodenum caused by a gallstone.     

Successful Removal of Massive Intragastric Gallstones by Endoscopic Electrohydraulic Lithotripsy and Mechanical Lithotripsy

We describe a case of massive gallstones discharged into the stomach through a cholecystoduodenal fistula and the successful removal of these stones by endoscopic electrohydraulic lithotripsy (EEHL) and endoscopic mechanical lithotripsy (EML) for the prevention of gallstone ileus. A 60-yr-old woman was admitted with epigastric pain and nausea. Upper gastrointestinal tract examination demonstrated backflow of contrast medium from the duodenal bulb into the gallbladder. Endoscopic examination revealed a large fistula on the anterior wall of the duodenal bulb, and two brown stones (about 3 cm in diameter) were found in the stomach. To prevent gallstone ileus, removal of these stones was attempted. They were broken into pieces by EEHL, then crushed into smaller pieces by EML and removed orally. Chemical analysis showed the composition of the gallstones to be at least 98% cholesterol. The patient was discharged one month after removal of the gallstones and has remained asymptomatic.     

Multiple giant duodenal gallstones causing gastric outlet obstruction: Bouveret's minefield revisited

Gastric outlet obstruction caused by a gallstone impacted in the duodenum is a rare entity known as Bouveret's syndrome. We report the unusual case of multiple large gallstones impacted in the duodenum from a cholecystoduodenal fistula in an 83-year-old lady. A high index of suspicion allowed for prompt diagnosis. Early surgical intervention was instituted because if the size and number of gallstones with an excellent outcome. The surgical strategies and underlying pitfalls underlying the management of this syndrome are critically reviewed and discussed.     

Acute upper gastrointestinal hemorrhage caused by gallstone impaction in the duodenal bulb

Summary An unusual case of upper gastrointestional hemorrhage caused by gallstone impaction in the duodenal bulb (Bouveret's syndrome) is reported. Endoscopy was used to make the diagnosis rapidly and surgery was performed to provide definitive treatment. Bouveret's syndrome must be kept in mind as a rare cause of upper gastrointestinal hemorrhage.     

Bouveret''s Syndrome Presenting as Upper Gastrointestinal Hemorrhage

A unique case of hematemesis is presented. The cause of upper gastrointestinal bleeding was a pyloroduodenal ulcer caused by erosion of a 5-cm gallstone impacted in the duodenal bulb. On review of the world literature of Bouveret's syndrome, this is the first case in which a preoperative diagnosis was well established and the fourth such case in which a successful surgical outcome was obtained.     

Giant duodenal gallstone presenting as gastric outlet obstruction: Bouveret's syndrome.

In a 91 year old woman with nausea and vomiting, the diagnosis of Bouveret's syndrome was considered when a barium meal disclosed a cholecystoduodenal fistula and a giant filling defect in the duodenum. Because of her age and underlying medical illness, operative therapy was initially deferred. Repeated attempts to remove the intermittently obstructing duodenal gallstone endoscopically were unsuccessful using both endoscopic retrograde cholangiopancreatography retrieval baskets and an endoscopic mechanical lithotripter. The patient was referred for definitive operative therapy, and was discharged after a successful and uneventful enterolithotomy.     

Electrohydraulic lithotripsy treatment of gallstone after disimpaction of the stone from the duodenal bulb (Bouveret's syndrome)

A 75-year-old man with right upper quadrant abdominal pain was diagnosed by gastroscopy to have an impacted gallstone in the duodenal bulb. Using the polypectomy loop, the stone was extracted from the bulbus and mobilized into the stomach. After failure to remove the stone from the stomach as well as fragmentation by mechanical lithotripsy, electrohydraulic lithotripsy was used to break up the stone, parts of which passed spontaneously through the bowel. Thus, it was unnecessary to proceed with surgical enterolithotomy to remove, from the duodenal bulb, the impacted gallstone responsible for the gastric outlet obstruction.     

Gallstone ileus: endoscopic removal of a gallstone obstructing the upper jejunum

In a 91-year-old female patient admitted with an ileus, ultrasound and computed tomography demonstrated the obstruction of the upper jejunum by a large gallstone. Due to concurrent diseases the patient was unfit for surgery. An attempt was made to remove the impacted stone endoscopically. After successful mobilization and fragmentation by mechanical lithotripsy the obstruction was cleared away. Since the patient improved considerably after this procedure, the gallbladder and the cholecystoduodenal fistula were left in place.     

Gallbladder carcinoma with choledochoduodenal fistula: a case report with surgical treatment.

A 79 year-old man was admitted to our hospital because of upper abdominal pain and nausea. A mobile tumor was palpable in the right upper abdomen. Abdominal ultrasonography, computed tomography and celiac angiography revealed a gallbladder tumor. Endoscopic retrograde cholangiopancreatography revealed a fistula 1.5 cm oral to the orifice of the papilla of Vater, dilatation of the common bile duct, and a filling defect in the gallbladder. Pancreatoduodenectomy associated with reconstruction using Imanaga's method was performed under a pre-operative diagnosis of gallbladder carcinoma with choledochoduodenal fistula. The gallbladder contained a tumor and two bilirubin stones impacted in the orifice of the duodenal papilla. Histological studies confirmed that the gallbladder tumor was a mucinous adenocarcinoma and had not infiltrated the bile duct. We speculated that choledochoduodenal fistula stimulated the development of cancer due to chronic irritation from pancreatic juice reflux.     

The Radiology Corner

A case of gallstone obturation of the duodenal bulb is presented. The general topic of gallstone ileus is briefly discussed and a review of the reported cases of Bouveret's syndrome is presented. The radiographic criteria for diagnosis of these entities are emphasized.     

Syndrome de Bouveret: cause rare de l’iléus biliaire

Bouveret’s syndrome is a pyloroduodenal obstruction by a gallstone migrated through a cholecystoduodenal fistula. We report the case of a patient of 59 years with epygastralgia and vomiting. The abdominal ultrasound and esogastroduodenal transit disclosed a huge gastric stasis upstream from a very tight postbulbar stenosis. Laparotomy found a large gallastone in the duodenum with cholecystoduodenal fistula.     

Bouveret's syndrome. Narrative review

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. Enterotomy or gastrotomy with or without cholecystectomy and fistula repair is the most common surgical therapy. It has high success rate, with acceptable surgical morbidity and mortality. Heightened awareness of this syndrome may lead to decreased morbidity and mortality.     

Complicated endoscopic management of Bouveret's syndrome. A case report and review

A rare case of gastric outlet obstruction due to a large gallstone (Bouveret's syndrome) presenting with abdominal pain and vomiting is reported. The endoscopic management of the gallstone was unsuccessful because of the size of the stone that got stuck in oesophagus. The final management of the patient was surgical and the gallstone was retrieved via a gastrotomy. The case report is followed by a brief review of Bouveret's syndrome.     

A case of jejunal perforation in gallstone ileus

Gallstone ileus is a rare but important cause of small bowel obstruction in the geriatric population. A 65-year-old man with a twenty year history of cholecystolithiasis was admitted to our hospital with abdominal pain and vomiting. Physical exams showed abdominal defence and rebound tenderness. A plain abdominal X-ray suggested a small bowel obstruction and pneumobilia. CT scan revealed a 2.5-cm gallstone at the jejunum and air in the biliary tree. The patient underwent a emergency laparotomy based on a diagnosis of panperitonitis with a perforation associated with gallstone ileus. Operative findings revealed a jejunal perforation and a impacted stone on the anal side of perforation. Enterolithotomy and jejunal resection were performed with cholecystectomy and repairment of the cholecystoduodenal fistula.     

Laparoscopic treatment of an upper gastrointestinal obstruction due to Bouveret’s syndrome

Bouveret’s syndrome is an extremely rare type of gallstone-induced ileus with atypical clinical manifestations,such as abdominal distension and pain,nausea and vomiting,fever or even gastrointestinal bleeding,which may easily be misdiagnosed. In the present case,a 55-year-old male was admitted to the hospital with upper gastrointestinal obstructive symptoms but without pain,fever,jaundice or melena. At first,gastrolithiasis and peptic ulcer combined with pyloric obstruction were suspected after gastroscopy revealed a large,hard stone in the duodenal bulb. A revised diagnosis of Bouveret’s syndrome was made following abdominal computed tomography. Subsequently,the patient exhibited a good postoperative recovery after laparoscopic duodenotomy for gallstone removal and subtotal cholecystectomy. The condition of the patient remained stable after being followed up for 6 mo. The successful application of laparoscopic therapy to treat Bouveret’s syndrome has seldom been reported. Laparoscopic enterolithotomy is safe and effective,with good patient tolerability,rapid postoperative recovery and few wound-related complications. The laparoscopic treatment of Bouveret’s syndrome is worth exploring.
