Bouveret Syndrome or Gallstone Ileus

Balancing Urgency and Strategy in the Surgical Management of a Complex Case of Gallstone Ileus: A Surgical-Video-Based Case Report of a 60-Year-Old Female

Gallstone ileus is an uncommon but potentially life-threatening complication of gallstone disease, characterized by the obstruction of the gastrointestinal tract by a gallstone, typically at the ileocecal valve. This condition predominantly affects elderly patients and carries a high risk of morbidity and mortality due to delayed diagnosis and the complexity of associated comorbidities. We report the case of a 60-year-old woman with a history of hypertension and cholelithiasis who presented with a four-day history of intermittent epigastric pain, nausea, vomiting, and an inability to pass stool or flatus. Initial imaging studies, including ultrasonography and computed tomography, revealed a biliary-enteric fistula with a large obstructing gallstone at the ileocecal valve. Despite conservative management with intravenous fluids, nasogastric tube suction, and antibiotics, the patient's symptoms persisted, necessitating surgical intervention. A midline laparotomy was performed, during which the gallstone was successfully removed via enterotomy. The patient recovered without complications and was discharged in stable condition. The complexity of management, particularly in elderly patients with multiple comorbidities, necessitates careful consideration between the one-stage and two-stage surgical approaches. In this case, the decision to perform an enterotomy without immediate cholecystectomy reflects a two-stage strategy, aimed at minimizing operative risk while addressing the immediate obstruction. This approach underscores the need for individualized management plans, where the choice between one-stage and two-stage surgery is guided by the patient's overall clinical status.

Combined laser and mechanical lithotripsy for endoscopic management of Bouveret's syndrome: A case report

Bouveret's syndrome (BS) represents an exceedingly rare clinical entity characterized by gastric outlet obstruction induced by a gallstone passing through a cholecystoduodenal, cholecystogastric or choledochoduodenal fistula and impacting in the duodenum or pylorus. Endoscopy is the preferred first-line therapy. It has a favorable safety profile, but requires high level of expertise to achieve stone clearance.

Gallstone ileus associated with cholecystogastric fistula: Case report, diagnosis and surgical treatment

Introduction

Gallstone Ileus is a rare complication of cholelithiasis, associated with multiple episodes of cholecystitis, with the formation of adhesions and fistulas between the gallbladder and adjacent organs. Its diagnosis is difficult, requiring complementary imaging tests such as computed tomography or radiography.

Presentation of case

Female patient, with intestinal obstruction for 7 days, associated with abdominal pain and previous episodes of pain in the right hypochondrium for 3 months. Abdominal CT scan identified aerobilia, gallstone impacted in the ileocecal valve and small loop dilatation, in addition to a probable cholecystogastric fistula. Opted for exploratory laparotomy, enterolithotomy and fistula correction in one surgical time.

Discussion

Gallstone ileus is rare among the complications of cholelithiasis, in addition to the fact that cholecystogastric fistula is associated with gastric pylorus obstruction and not impaction on the ileocecal valve. Imaging tests are useful to complement the diagnosis, and if Rigler's triad is present, the suspicion of gallstone ileus is increased. The presence of fistula between the gallbladder and stomach presents a frequency between 0 and 13.3%. There is no gold standard treatment for gallstone ileus, but surgery options for each type of patient and severity level.

Conclusion

There is no definitive protocol for optimal surgical treatment for biliary ileus, but the possibility of enterolithotomy associated with cholecystectomy and fistula correction can be evaluated in selected patients.

•

Gallstone ileus is a rare cause of intestinal obstruction.

•

Cholecystogastric fistula may be associated with ileum obstruction.

•

One-step surgical treatment can be used in specific patients

[Differential diagnosis of gallbladder abnormalities : Ultrasound, computed tomography, and magnetic resonance imaging]

CLINICAL ISSUE

Due to the high prevalence of clinically suspected cholecystitis or cholecystolithiasis the gallbladder is one of the organs examined the most by imaging.

STANDARD RADIOLOGICAL METHODS

In most clinical settings ultrasound is the primary imaging method because of its wide availability, speed and superior spatial resolution. In cases of ambiguous findings or potential complications computed tomography (CT) and magnetic resonance imaging (MRI) are used.

METHODICAL INNOVATIONS

When specific problems arise these imaging modalities may be enhanced by special techniques, e. g. contrast-enhanced ultrasound or dual-energy CT, and specific MRI sequences.

PERFORMANCE

Special variants of cholecystitis, such as xanthogranulomatous cholecystitis and adenomyomatosis, may pose a particularly difficult diagnostic problem as they may resemble other diseases. Sequelae of cholecystolithiasis, such as the Mirizzi syndrome and acute bowel obstruction, may complicate the imaging algorithm as the location and the symptoms shift. Cases of neoplastic diseases of gallbladder cancer and other malignancies require a broad spectrum of imaging modalities.

ACHIEVEMENTS

Although the gallbladder can easily be examined with ultrasound, some cases require a more thorough ultrasound examination. In some cases only a combination of multiple imaging modalities yield the diagnosis. Further developments regarding technical issues and the diagnostic algorithm can be expected.

PRACTICAL RECOMMENDATIONS

Ultrasound is the best first imaging modality. In cases of ambiguous findings or clinical complications CT or MRI are recommended.
