          Abstract

          Bouveret syndrome is a rare complication of cholelithiasis that usually presents with signs and symptoms of gastric outlet obstruction. Given the relative rarity of this condition, there are no standardized guidelines for the management of this condition. In this paper, we review the diagnosis and management options (endoscopic, laparoscopic, and open approaches) of patients with Bouveret syndrome, including a report of one case to illustrate some of the endoscopic and surgical principles of management.

          Gallstone ileus: a review of 1001 reported cases.

          Although rare in the general population, gallstone ileus accounts for 25 per cent of nonstrangulated small bowel obstructions in those over the age of 65. While mortality has declined over the years, it remains high at 15-18 per cent. This is largely due to the patient population, with comorbid medical conditions contributing to mortality. The proper extent of surgery continues to be actively debated. Proponents of minimal surgery feel that relief of the obstruction is all that is required. Others argue that the gallbladder and biliary-enteric fistula must be removed to prevent future recurrence (a one-stage procedure). The one-stage procedure carries an associated mortality of 16.9 per cent, compared to 11.7 per cent for simple enterolithotomy. Morbidity after enterolithotomy is low. The recurrence rate of gallstone ileus was less than 5 per cent, and only 10 per cent of patients required reoperation for continued symptoms related to the biliary tract. Simple enterolithotomy is both safe and effective in dealing with a patient with gallstone ileus.

            Characterization of Bouveret's syndrome: a comprehensive review of 128 cases.

            The aim of the study was to characterize the clinical presentation, evaluation, and therapy of Bouveret's syndrome, by comprehensively reviewing all the identified previously reported cases, to facilitate early diagnosis and thereby to improve the prognosis. Relevant articles were identified by MEDLINE computerized searches, by consultation with all available reference books, and by review of the first author's teaching files. A new case in which the diagnosis of Bouveret's syndrome was missed at esophagogastroduodenoscopy (EGD)--despite endoscopic findings of gastric outlet obstruction caused by a hard, nonfleshy, and convex pyloric mass--prompted this review. Review of 128 reported cases identified syndromic characteristics. Patients on average were 74.1 +/- 11.1 (SD) yr old. The female-to-male sex ratio was 1.86. Prominent symptoms were nausea and vomiting in 87%, abdominal pain in 71%, hematemesis in 15%, recent weight loss in 14%, and anorexia in 13% of patients. Prominent signs were abdominal tenderness in 44%, signs of dehydration in 31%, and abdominal distention in 26% of patients. Endoscopy revealed gastroduodenal obstruction in nearly all cases, but identified the obstructing stone in only 69%. Abdominal ultrasound or computerized tomography was diagnostic in about 60% of cases. The following endoscopic findings are suggestive of Bouveret's syndrome: a dilated stomach containing old digested food from gastrointestinal obstruction together with a hard and nonfleshy mass at the obstruction. These endoscopic findings, in the setting of the currently reported characteristic epidemiologic and clinical findings, should strongly suggest this syndrome. Abdominal ultrasound or computerized tomography is recommended to confirm and extend the endoscopic diagnosis.

              Bouveret Syndrome—The Rarest Variant of Gallstone Ileus: A Case Report and Literature Review

              We present a case report of a patient with Bouveret syndrome with interesting radiological findings and successful surgical treatment after failure of the endoscopic techniques. The report is followed by a review of the literature regarding the diagnostic means and proper treatment of this rare entity. Bouveret syndrome refers to the condition of gastric outlet obstruction caused by the impaction of a large gallstone into the duodenum after passage through a cholecystoduodenal fistula. Many endoscopic and surgical techniques have been described in the management of this syndrome. This is a case of a 78-year-old patient with severe medical history who presented in bad general condition with an 8-day history of nausea, multiple bilious vomiting episodes, anorexia, discomfort in the right hypochondrium and epigastrium, and fever up to 38,5°C. The diagnosis of Bouveret syndrome was set after performing the proper imaging studies. An initial endoscopic effort to resolve the obstruction was performed without success. Surgical treatment managed to extract the impacted gallstone through an enterotomy after removal into the first part of the jejunum.
