Bouveret-szindróma

Összefoglaló. A Bouveret-szindróma egy bilioenteralis fistulán keresztül a vékonybélbe – az esetek 85%-ában a duodenumba – jutó nagy epekő okozta bélelzáródást jelenti. Leggyakrabban idős nők körében fordul elő. Jelen közleményünk célja e kórkép tüneteinek, diagnosztikájának és terápiás lehetőségeinek ismertetése egy esetbemutatás kapcsán. A 79 éves nőbeteg felvételi hasi panaszainak hátterében típusos gyomorkimenet-obstrukciós szindrómát okozó, a duodenumban beékelődött epekő, Bouveret-szindróma igazolódott. A diagnózist az elvégzett natív hasi röntgen és hasi ultrahangvizsgálatok már felvetették, de megerősítésére további képalkotó vizsgálatot (hasi CT) és endoszkópos beavatkozást végeztünk. Ezt követően sebészeti beavatkozás történt, melynek során a cholecystoduodenalis fistula zárása és az epekő eltávolítása után a beteg gyógyultan távozott. Közleményünkben a diagnózisfelállítás idejének fontosságáról, illetve a terápiás lehetőségekről számolunk be, valamint szeretnénk felhívni a figyelmet az epekő okozta gyomorürülési zavar ezen ritka formájára.

Bouveret syndrome is a rare form of bowel obstruction resulting to the small intestine – in 85% of the cases to the duodenum – caused by a gallstone from a bilioenteral fistula. It occurs most commonly in elderly women. The aim of the present study is to describe the symptoms, diagnostic and therapeutic options of Bouveret syndrome due to our case report. The background of epigastric pain of the 79-year-old woman was the typical gastric outlet obstruction syndrome caused by Bouveret syndrome with an impacted gallstone into the duodenum. This diagnosis was suggested by abdominal X-ray and abdominal ultrasound; however, it was confirmed with abdominal computer tomography and upper gastrointestinal endoscopy. This was followed by surgical intervention to close the cholecystoduodenal fistula and remove the gallstone, finally the cured patient was discharged. In our study, we summarize the importance of timely diagnosis and therapeutic options, respectively, furthermore, draw attention to this rare form of gallstone-caused gastric outlet obstruction syndrome.

Cholecysto-pyloric fistula with submucosal impaction of gall stone causing gastric outlet obstruction masquerading as a gastric mass, Bouveret Syndrome: case report

Background Cholecysto-enteric fistula is a rare complication of cholelithiasis and cholecystitis. Another even rarer complication is proximal impaction of gallstone(s) in gastric pylorus leading to gastric outlet obstruction, known as the Bouveret Syndrome. Only a few cases have been reported in the available literature. It can be confused with a malignant thickening at the pylorus, knowledge of this syndrome helps in arriving at the right diagnosis. Case report A 52-year-old female patient, who was admitted to our hospital for evaluation of recurrent vomiting and abdominal pain. She was investigated with various imaging modalities including upper gastrointestinal (GI) endoscopy, abdominal ultrasonography as well as Contrast Enhanced Computerized Tomography (CECT) scan of the abdomen. On the outside scan, it was given as a malignant thickening at the pylorus. However, current radiologists felt that imaging findings were not of a typical malignant mass, and suspicion of Bouveret syndrome was given. Intraoperative findings confirmed the diagnosis of Bouveret syndrome. The patient has not experienced any postoperative complications till now. Conclusion Bouveret syndrome is associated with significant morbidity and mortality. Being familiar with the imaging appearance of this condition, and differentiating it with malignant thickening can help radiologists avoid unnecessary invasive procedures in such patients. Being a benign etiology, it also helps in a better prognosis.
