Bouveret's syndrome: endoscopic or surgical treatment

Síndrome de Bouveret como variante de íleo biliar

Introducción. El síndrome de Bouveret es una variante del íleo biliar, de rara presentación dentro de las causas de obstrucción intestinal, generada por la impactación de un lito biliar a nivel del duodeno, secundario a la formación de una fístula bilioentérica. Es más común en mujeres en la octava década de la vida, con múltiples comorbilidades. y presenta síntomas inespecíficos, documentándose la triada de Rigler hasta en el 80 % de las tomografías de abdomen. La cirugía sigue siendo el tratamiento de elección. Caso clínico. Presentamos el caso de una paciente de 76 años, con múltiples antecedentes y cuadros previos de cólico biliar, que consultó por dolor abdominal y signos de hemorragia de vías digestivas altas y se documentó un síndrome de Bouveret. Fue tratada en la misma hospitalización mediante extracción quirúrgica del cálculo con posterior resolución de su sintomatología. Conclusión. A pesar de que el síndrome de Bouveret es una entidad de infrecuente presentación, los cirujanos generales deben estar familiarizados con esta patología, en el contexto del paciente que consulta con un cuadro de obstrucción intestinal, conociendo el valor de la tomografía de abdomen y la endoscopia de vías digestivas altas, teniendo en cuenta la edad y las condiciones del paciente para definir el manejo quirúrgico más adecuado.

Bouveret Syndrome: A Systematic Review of Endoscopic Therapy and a Novel Predictive Tool to Aid in Management

BACKGROUND AND GOALS

Bouveret syndrome is characterized by gastroduodenal obstruction caused by an impacted gallstone. Current literature recommends endoscopic therapy as the first line of intervention despite significantly lower success rates compared with surgery. The lack of treatment efficacy studies and the paucity of clinical guidelines contribute to current practices being arbitrary. The aim of this systematic review was to identify factors that predict outcomes of endoscopic therapy. Subsequently, a predictive tool was devised to predict the success of endoscopic therapy and recommendations were proposed to improve current management strategies of impacted gallstones in the upper gastrointestinal tract.

METHODS

A systematic search of PubMed, Medline, Cochrane, and Scopus was performed for articles that contained the terms "Bouveret syndrome," "Bouveret's syndrome," "gallstone" AND "gastric obstruction" and "gallstone" AND "duodenal obstruction" that were published between January 1, 1950 to April 15, 2018. Articles were reviewed by 3 reviewers and raw data collated. χ and Kolmogorov-Smirnov tests were used to test associations between predictors and endoscopic outcomes. A logistic regression model was then used to create a predictive tool which was cross validated.

RESULTS

Failure of endoscopic therapy is associated with increasing gallstone length (P<0.0001) and impaction in the distal duodenum (P<0.05). Using multiple endoscopic modalities is associated with better success rates (P<0.05). The novel predictive tool predicted success of endoscopic therapy with an area under the receiver operating characteristic score of 0.86 (95% confidence interval: 0.79-0.94).

CONCLUSION

In Bouveret syndrome, a selective approach to endoscopic therapy can expedite definitive treatment and improve current management strategies.

Bouveret's syndrome as a rare complication of cholelithiasis: Disputes in current management and report of two cases

•

Bouveret’s syndrome is a rare complication of cholelithiasis that determines an unusual type of gallstone ileus.

•

This syndrome is associated with high morbility and mortality rates.

•

Diagnosis of Bouveret’s syndrome is difficult because of non-specific symptoms and its rarity.

•

Here are no guidelines for the diagnostic work up and the correct management of this pathology.

•

The endoscopic or surgical management should be tailored to the patient’s clinical presentation and morbidities.

Introduction

Bouveret’s syndrome is a rare complication of cholelithiasis that determines an unusual type of gallstone ileus, secondary to an acquired fistula between the gallbladder and either the duodenum or stomach with impaction of a large gallbladder stone. Preoperative diagnosis is difficult because of its rarity and the absence of typical symptoms. Adequate treatment consists of endoscopic or surgical removal of obstructive stone.

Presentation of cases

Two old females patients were admitted to the Emergency Department with a history of abdominal pain associated with bilious vomiting. Physical examination revealed abdominal distension with tympanic percussion of the upper quadrants, abdominal pain on deep palpation of all quadrants and in the first patient positive Murphy’s sign. Preoperative diagnosis of gallstone impacted in the duodenum was obtained by abdominal computed tomography (CT) scan in the first patient and by esophagogastroduodenoscopy in the second one. Both patients underwent surgery with extraction of the gallstone from the stomach. Postoperative course of two patients was uneventful and they were discharged home.

Discussion

Bouveret’s syndrome usually presents with signs and symptoms of gastric outlet obstruction. Preoperative radiological investigations not always are useful for its diagnosis. Appropriate treatment, endoscopic or surgical, is debated and must be tailored to each patient considering medical condition, age and comorbidities.

Conclusion

Bouveret’s syndrome is a very rare complication of cholelithiasis, difficult to diagnose and suspect, because of lack of pathognomonic symptoms. Nowaday there are no guidelines for the correct management of this pathology. Endoscopic or surgical removal of obstructive stone represents the correct treatment.

Bouveret's syndrome: A rare presentation of gastric outlet obstruction

Bouveret's syndrome refers to gastric outlet obstruction caused by the formation of a cholecystoduodenal fistula with subsequent migration and impaction of a large gallstone into the duodenum. A case of a 59-year-old male who presented to our institution with consistent abdominal pain and nausea is reported herein. Bouveret's syndrome was diagnosed after conducting a computed tomography scan. Surgery was performed wherein gallstone removal was followed by cholecystectomy and fistula repair associated with a pyloric bypass via gastro-jejunostomy. The patient recovered well following surgery and has remained free of symptoms for the last year.

Rare cause of gastric outlet obstruction

Bouveret’s syndrome is a rare cause of gastric outlet obstruction. The stones enter the small bowel via cholecysto-enteric fistula. The most common presenting symptoms are abdominal pain, nausea and vomiting. The gold standard diagnostic test isesophagogastroduodenoscopy (EGD). Rigler’s triad on abdominal x-ray is classic. CT scan findings are pneumobilia, cholecystoduodenal fistula and a gallstone in the duodenum. We present a case of a 75-year-old female who presents with 3 week history of nausea, vomiting, and diffuse abdominal pain. Initial presentation, imaging and EGD was concerning for malignancy. She was later diagnosed to have Bouveret’s syndrome and underwent laparoscopic small bowel enterotomy with removal of gallstones

Uncommon presentation of a common disease - Bouveret's syndrome: A case report and systematic literature review

AIM

To investigate and summarise the current evidence surrounding management of Bouveret's syndrome (BS).

METHODS

A MEDLINE search was performed for the BS. The search was conducted independently by two clinicians (Yahya AL-Habbal and Matthew Ng) in April 2016. A case of BS is also described.

RESULTS

A total of 315 articles, published from 1967 to 2016, were found. For a clinically meaningful clinical review, articles published before 01/01/1990 and were excluded, leaving 235 unique articles to review. Twenty-seven articles were not available (neither by direct communication nor through inter-library transfer). These were also excluded. The final number of articles reviewed was 208. There were 161 case reports, 13 reviews, 23 images (radiological and clinical images), and 11 letters to editor. Female to male ratio was 1.82. Mean age was 74 years. Treatment modalities included laparotomy in the majority of cases, laparoscopic surgery, endoscopic surgery and shockwave lithotripsy.

CONCLUSION

There is limited evidence in the literature about the appropriate approach. We suggest an algorithm for management of BS.

Novel treatment options for Bouveret's syndrome: a comprehensive review of 61 cases of successful endoscopic treatment

In Bouveret's syndrome, a biliary stone obstructs the duodenum. Surgical treatment is plagued by high morbidity and mortality. Therefore, endoscopic treatment has become a first-line approach. Areas covered: A literature search of Medline and Google Scholar databases was performed using the terms endoscopic treatment, non-operative treatment, Bouveret's syndrome, and gallstone ileus. Sixty-one cases of successful endoscopic treatment were found over the period 1978-2016 and are summarized herein. Therapeutic modalities used in 52 patients with complete success included mechanical lithotripsy (40% of cases), electrohydraulic lithotripsy (21% of cases), extraction of the intact stone and laser lithotripsy (15% of cases each), extracorporeal shockwave lithotripsy and duodenal stenting (4% of cases each). In the remaining 9 patients, stone fragments migrated distally and required surgical removal. Cholecystectomy was performed in five (8.2%) of 61 patients and gallbladder cancer was detected in three (4.9%) patients. Expert commentary: Meticulous preparation, including that of instruments, personnel, patient anesthesia, and X-ray availability, is key to success in this unusual situation. Partial success (stone fragmentation and mobilization to another location) may render surgery easier as these patients present with dense adherences in the right upper quadrant. Cholecystectomy is reserved for highly selected patients (e.g. relapsing ileus, gallbladder cancer).

Bouveret's syndrome: presentation of two cases with review of the literature and development of a surgical treatment strategy

BACKGROUND

Bouveret's syndrome causes gastric outlet obstruction when a gallstone is impacted in the duodenum or stomach via a bilioenteric fistula. It is a rare condition that causes significant morbidity and mortality and often occurs in the elderly with significant comorbidities. Individual diagnostic and treatment strategies are required for optimal management and outcome. The purpose of this paper is to develop a surgical strategy for optimized individual treatment of Bouveret's syndrome based on the available literature and motivated by our own experience.

CASE PRESENTATION

Two cases of Bouveret's syndrome are presented with individual management and restrictive surgical approaches tailored to the condition of the patients and intraoperative findings.

CONCLUSIONS

Improved diagnostics and restrictive individual surgical approaches have shown to lower the mortality rates of Bouveret's syndrome. For optimized outcome of the individual patient: The medical and perioperative management and time of surgery are tailored to the condition of the patient. CT-scan is most often required to secure the diagnosis. The surgical approach includes enterolithotomy alone or in combination with simultaneous or subsequent cholecystectomy and fistula repair. Lower overall morbidity and mortality are in favor of restrictive surgical approaches. The surgical strategy is adapted to the intraoperative findings and to the risk for secondary complications vs. the age and comorbidities of the patient.
