Bouveret syndrome-the rarest variant of gallstone ileus: a case report and literature review

Complex presentation of Bouveret syndrome: Gastric outlet obstruction and septic complications

Bouveret syndrome, a rare form of gastric outlet obstruction, occurs when a large gallstone migrates through a cholecystoenteric fistula into the duodenum, causing obstruction. We report a 31-year-old female who initially presented with nausea, vomiting, and abdominal pain. Imaging identified a large, calcified gallstone, a hepatic abscess, and acute cholecystitis. Initial treatment involved drainage of the hepatic abscess and antibiotics, with plans for elective cholecystectomy. Three years later, she returned with recurrent symptoms, including early satiety, significant weight loss, and gastric outlet obstruction. Endoscopy confirmed duodenal obstruction, and further imaging revealed a cholecystoduodenal fistula. She underwent an open cholecystectomy with fistula excision, duodenal repair, and nasojejunal feeding tube placement. Her postoperative recovery was smooth, with a gradual return to enteral nutrition. This report presents essential diagnostic and treatment approaches for Bouveret syndrome, including the roles of imaging, endoscopy, and surgery in managing complex cases. Early recognition and a coordinated, individualized treatment plan are crucial to optimizing outcomes in this rare condition.

Case report: open surgical management of Bouveret syndrome

Bouveret syndrome is a rare type of gallstone ileus, where a gallstone obstructs the duodenum due to a cholecystoduodenal fistula, accounting for 1-3% of cases, predominantly in women. The presentation of Bouveret syndrome is often nonspecific, including acute cholangitis, nausea, vomiting, and abdominal pain, with significant morbidity and mortality risks. We report a 73-year-old man with complicated gallstone ileus, presenting with abdominal pain, nausea, and vomiting. Imaging revealed a 3-cm stone located in the proximal duodenum and was suspected to be associated with a choledochoenteric fistula. The procedure started laparoscopically but was converted to open surgery, successfully removing the stone. Postoperatively, the patient required bowel rest and total parenteral nutrition. He was discharged with a gastrostomy tube and a Jackson-Pratt drain for outpatient follow-up. A standardized surgical protocol that includes both endoscopic and open techniques should be investigated for effective management of Bouveret syndrome.

Gall Stone Ileus and Recurrence: Management Dilemma for the Operating Surgeon

Gallstone ileus (GSI) is a rare complication of gallstone disease. It occurs as a result of the passage of a stone from the biliary tract into the gastrointestinal tract via an abnormal pathway (bilio-enteric fistula). Chronic inflammatory processes result in gall bladder adhering and subsequently eroding into the intestines, leading to a fistula. It is a surgical emergency seen in the elderly who often present as being unwell, with abdominal pain, distension, and vomiting. Imaging such as a CT scan is diagnostic in confirming small bowel obstruction. Management usually involves relief of obstruction by removing the impacted gallstone. Despite surgical intervention, a small proportion of patients develop recurrent symptoms or recurrent gallstone ileus, usually within a few weeks of initial presentation. The recurrence of symptoms during index admission is extremely rare and can be challenging to diagnose and manage. The morbidity and mortality remain high in elderly patients. We report an 89-year-old patient who presented with small bowel obstruction. The CT scan confirmed gallstone ileus as a result of a stone impacted in the mid-small bowel. The patient had a laparotomy with extraction of the stone. No migrating stones were felt proximally. Five days postoperatively, he developed recurrent gallstone ileus confirmed on a CT scan and had to undergo another surgery to relieve the obstruction. We aim to investigate various management strategies for recurrent gallstone ileus, ranging from the commonly practiced approach of simple stone extraction to more definitive surgical interventions, including fistula repair, which may provide a more comprehensive solution.

Lesser Omental Infarction: Clinical Insights and Diagnostic Challenges in a Rare Case of Acute Abdominal Pain

Intraperitoneal focal fat infarction (IFFI) is a rare condition characterized by infarction of fatty tissue within the abdominal cavity. Lesser omental infarction, a relatively rare type of IFFI, occurs when there is an infarction of fat within the lesser omentum. Patients typically present with acute abdominal pain that can mimic more serious conditions. This case report highlights the clinical presentation, diagnostic challenges, and management strategies for patients presenting to the emergency department with lesser omental infarction. A 63-year-old female presented to the emergency department with a chief complaint of epigastric abdominal pain that had been persisting for approximately a week and a half. The pain, which initially seemed like a sore muscle, became increasingly sharp and intermittent, with tenderness upon palpation of the epigastric area. Computed tomography (CT) imaging revealed an omental infarct in the lesser sac with focal inflammation in the fat of the lesser omentum. Through conservative management with analgesics and anti-inflammatory medication, the patient experienced resolution of her symptoms within a few days and had a follow-up with the gastrointestinal team several weeks later. Lesser omental infarction typically results from compromised blood flow due to torsion or thrombosis, leading to ischemia and necrosis of the fatty tissue. CT imaging is crucial for its diagnosis and reveals fat-density lesions with surrounding inflammatory changes. Conservative management is typically effective, though in rare cases, surgical intervention may be necessary when significant vital signs and electrolyte derangements occur.

Bouveret Syndrome: Etiology, Clinical Presentation, Differential Diagnosis, Complications, and Treatment Options

Bouveret syndrome is one of the complications of gallstone disease possibly fatal, which proposes the presence of a large stone obliterating the lumen of the duodenum or stomach because of the formation of a bilioenteric fistula. This review article, therefore, plans to review the causes, patient characteristics, diagnostic workup, associated conditions, and treatment of Bouveret syndrome. A literature search was also performed through scientific databases such as Scopus, Google Scholar, and PubMed concerning articles related to Bouveret syndrome written by different authors. The terms employed for the search were bilioduodenal fistula, Bouveret syndrome, gastric outlet obstruction, and gallstone ileus. Both case reports and systematic reviews that were written in the English language and published between the years 2000 and 2024 were considered. Finally, the review establishes the relevant concerns surrounding the diagnosis of Bouveret syndrome, focusing on the diagnosing issues. It emphasises the need for some specialities' involvement and focuses on the importance of endoscopic intervention. For patients, endoscopy remains the first line of treatment, while surgery is necessary in cases where conservative methods cannot be used. The article also focuses on new approaches to treating the conditions, such as percutaneous gallbladder stone dissolution. Latterly, further developments in minimally invasive surgery pertain to refining methods, including endoscopic removal and lithotripsy, to improve the survival rate of patients. Further investigation is required, especially regarding the administration schedule in relation to this disorder and goals that can reduce mortality and morbidity, especially in elderly patients with comorbid diseases.

Surgical Strategy in Bouveret's Syndrome: Report of a Case With One-Stage Surgery

Bouveret's syndrome is a rare condition caused by a gallstone that impacts the duodenum via a cholecystoduodenal fistula and obstructs the gastric outlet. Despite its high mortality rate, the treatment strategy for Bouveret's syndrome is debatable and frequently challenging. The main issue is whether cholecystectomy and fistula repair following stone extraction should be performed concurrently with one-stage surgery. We present a case of Bouveret's syndrome that was treated with one-stage surgery using a bailout procedure.

Upper gastrointestinal bleeding revealing a Bouveret syndrome: A case report

Bouveret's syndrome is an uncommon cause of gastrointestinal obstruction. It's a result of the passage of a gallstone through a fistula connecting the gallbladder with the duodenum or stomach. The diagnosis is challenging due to its atypical clinical manifestations. There have been a few reported cases of Bouveret syndrome presenting with gastrointestinal bleeding. Treatment options include both endoscopic and surgical approaches. We present the case of a 92-year-old woman admitted to the emergency department for upper gastrointestinal bleeding. Gastroscopy revealed gastric stasis upstream of a calculus inducing an obstruction of the bulb. The computed tomography (CT) scan showed a cholecystoduodenal fistula with a calculus lodged in the bulb. The patient underwent a gastrostomy with extraction of the calculus. Postoperative course was uneventful and the patient was discharged home. In the majority of cases, Bouveret's syndrome is revealed by an upper gastrointestinal obstruction, but other signs, such as gastrointestinal bleeding, can be seen. The diagnosis is confirmed by an imaging method that highlights Rigler's triad. The management can be either endoscopic or surgical depending on the patient's general condition. The diagnosis is often difficult due to the lack of specificity in the symptoms. Presently, there exists no consensus concerning the appropriate approach for its management.

Gallstone Ileus With Cholecystoenteric Fistula in an Elderly Female: A Case Report

Mechanical small-bowel obstruction can occur due to various reasons, including the impaction of a gallstone in the ileum after it has passed through a cholecystoenteric fistula. Gallstone ileus is an infrequent yet significant cause of this condition. This case report documents an instance of gallstone ileus, which accounts for less than 1% of patients with mechanical small bowel obstruction. We report a 75-year-old female patient who presented with colicky pain in both upper quadrants, hyporexia, and constipation that worsened during a period of nine days, which subsequently was accompanied by nausea and vomiting of bilious appearance in the next three days. Abdominal CT reported a dilated common bile duct (1.7 cm) with multiple stones inside measuring between 5 and 8 mm associated with pneumobilia of intrahepatic bile ducts and dilatation of small intestinal loops produced by a high-density image of approximately 2.5 cm. Laparoscopic exploration showed an obstructive mass measuring 15 cm from the ileocecal valve corresponding to a 2.54 x 2.35 cm gallstone, which was removed and enterorrhaphy was performed. The sine qua non condition for gallstone ileus to occur is the presence of a fistula between the gallbladder and the gastrointestinal tract. The treatment is mainly surgical and should be aimed primarily at the intestinal obstruction and secondarily at the cholecystoenteric fistula. This condition tends to have a high rate of complications and consequently long hospital stays. Making a timely diagnosis provides us with the tools for a surgical approach aimed at intestinal obstruction and subsequently in the management of the biliary fistula.

Bouveret syndrome: a rare complication of gallstone disease

A Caucasian man in his late 80s was admitted with central abdominal pain, abdominal distension and continuous vomiting, on the background of a recent admission for acute cholecystitis. The patient was managed for subacute bowel obstruction and was admitted to general surgery for further investigation. His blood tests showed raised inflammatory markers and deranged liver function tests. A CT scan showed the migration of a large gallstone, previously seen in the neck of the gallbladder on prior admission, to the proximal duodenum causing a degree of gastric outlet obstruction. A diagnosis of Bouveret syndrome was made, and although initially managed conservatively, the patient ultimately underwent surgery to remove the gallstone which had relocated again to the terminal ileum. Our case highlights the importance of considering rare complications such as Bouveret syndrome in patients presenting with bowel obstruction, particularly in the context of recent or chronic cholecystitis.

Synchronous Gallstone Ileus and Bouveret’s Syndrome: A Report of Two Rare Concurrent Complications of Gallstone Disease

Cholecystoenteric fistulas occur as a result of a chronic inflammatory insult involving the gallbladder and the erosion of both its wall and a bowel segment. When the fistula develops, it creates a pathway for gallstones to migrate and cause an intestinal obstruction, known as gallstone ileus. When it obstructs the gastric outlet, a proximal variant of gallstone ileus occurs, known as Bouveret's syndrome. A 65-year-old man presented to the emergency department with a three-day history of epigastric and right upper quadrant pain and persistent vomiting, preceded by unintentional weight loss of 15 kg over three months. Endoscopic and complementary imaging studies identified a concurrent gastric outlet obstruction caused by a lodged gallstone in the duodenal bulb and gallstone ileus. The patient underwent an urgent exploratory laparotomy and was submitted to an enterolithotomy and gastrolithotomy. Due to a sudden deterioration on the fourth postoperative day, he underwent an emergent re-laparotomy that found fecal peritonitis and complete dehiscence of both closures. The patient was then managed with damage control surgery. An atypical gastric resection and enterectomy of the distal ileum were performed and the patient was admitted to the intensive care unit in temporary abdominal closure (laparostomy). The patient failed to improve and died on the same day. Ultimately, the patient's multiple comorbidities, including morbid obesity, malnutrition, and diabetes, contributed to poor tissue healing and the fatal outcome. Gallstone ileus and Bouveret's syndrome are two rare complications of cholecystoduodenal fistulas that have not yet been reported to occur simultaneously. Both intestinal and gastric obstruction makes the surgical approach the first-line treatment.

Two unique cases of Bouveret syndrome with review of literature

Bouveret syndrome is a rare form of gallstone ileus in which a proximally lodged gallstone in the duodenum causes a gastric outlet obstruction. It is a rare condition that can be challenging to manage. Although endoscopic management remains first line, a surgical approach can be needed. We present two cases of Bouveret syndrome. A 65-year-old man with oral squamous cell carcinoma treated with endoscopic management and a 63-year-old woman treated with surgery.

Bouveret's Syndrome: A Case Series and Literature Review on a Gallstone Disease Causing Gastric Outlet Obstruction

Introduction Bouveret's syndrome refers to a gastric outlet obstruction due to the impaction of a large gallstone following retrograde migration via a bilio-duodenal fistula. Although no clear management guideline has been formulated, different treatment modalities have been described, including endoscopic stone removal using classical endoscopic devices, like snares and forceps, or fragmentation of stones with new devices, such as lasers and extracorporeal shockwave lithotripsy (ESWL). Results This case series reports six patients who have been diagnosed with Bouveret's syndrome and have presented with interesting radiological and endoscopic findings. The report is followed by a literature review, including diagnostic and management options for this rare condition. Discussion Cholelithiasis is a common condition occurring in the general population and may develop rare complications such as cholecystoduodenal fistula. Bouveret's syndrome presents with a clinical picture similar to that of gastric outlet obstruction, and laboratory findings are often consistent with an obstructive jaundice picture. The use of endoscopic treatment with a range of different lithotripsy modalities has been described to manage this condition. Conclusion The diagnosis of Bouveret's syndrome is made after performing appropriate imaging studies. The first-line management option is endoscopic treatment. If this fails, surgical intervention is recommended.

Unusual Presentation of Bouveret Syndrome Resulting in Both Gastric Outlet Obstruction and Small Bowel Obstruction with Perforation

Our case describes an 83-year-old female who presented with severe abdominal pain, nausea, and bilious emesis of one day's duration. She had an endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and percutaneous transhepatic biliary drainage (PTCD) one year prior for choledocholithiasis with acute cholangitis in her home country, Scotland. Unfortunately, while visiting family in the United States, her PTCD became dislodged, and she developed progressive worsening abdominal pain. Computerized tomography of her abdomen showed pneumobilia, perigastric inflammation, a contracted gallbladder, small bowl inflammation with a likely transition point at the mid-jejunum, and a probable duodenal mass. The patient underwent an exploratory laparotomy with intraoperative findings of choledochoduodenal fistula with coincident gastric and small bowel obstruction (SBO) secondary to three large, mixed gallstones. One 3 cm gallstone was located at the pylorus and two (2.3 and 3 cm) gallstones were isolated in the mid-jejunum, with one of those causing isolated transmural pressure necrosis with subsequent perforation. Bouveret syndrome is a rare cause of gastric outlet obstruction (GOO) that manifests via an acquired cholecystoenteric fistula. Our patient presented with a concomitant GOO and SBO with perforation of the mid-jejunum. Timely diagnosis of Bouveret syndrome is essential, as most causes require emergent surgical intervention.

Cholecystogastric fistula in Bouveret syndrome: Case report and literature review

INTRODUCTION AND IMPORTANCE

Cholelithiasis is the benign bile pathology with major prevalence. A rare condition has been described, when a stone migrates through the duodenum causing small bowel obstruction (SBO), it's known as Bouveret syndrome, and it's attributed to almost 5% of SBO. Just 2% of the cases present with the migration of the stone through a fistula between gastric chamber and gallbladder, with limited reports in the literature.

CLINICAL FINDINGS

We present a case of an 87-year-old male with Bouveret syndrome and a cholecystogastric fistula with a stone in the gastric chamber who underwent laparoscopic gastrotomy to resolve the clinical case.

CONCLUSION

Bouveret syndrome remains to be a rare condition in benign bile pathology. Individualized treatment should be performed and multidisciplinary approach leads to improved outcomes for the patient.

A rare cause of duodenal obstruction: Bouveret syndrome

Gallstone ileus is a relatively rare pathology, most commonly obstructing the terminal ileum. Bouveret syndrome, leading to gastric outlet obstruction and seen with an incidence of less than 1%, is a syndrome met particularly in elderly patients and develops as the result of cholecysto-enteric fistula. In this report, it was aimed to present a 95-year-old case diagnosed with Bouveret syndrome.

Facing the unexpected: unusual causes of mechanical small bowel obstruction in adults

Mechanical small bowel obstruction in adults is a common emergency condition that typically requires hospitalisation and usually acute surgical intervention. The majority of the cases are due to adhesive obstruction or common abdominal wall hernias or relevant related past history. However, the surgeons might face unexpected challenges in this concept due to rare causes of this condition. This paper explores in depth the challenges encountered by the emergency general surgeons in the concept of management of rare causes of mechanical small bowel obstruction in adults through a systematic review and critical analysis of the available evidence, and summarises the essential intra-operative steps that are needed to be taken accordingly. In conclusion, the emergency surgeons should be familiar with the uncommon/rare causes of mechanical small bowel obstruction in adults to avoid serious complications. Successful outcomes are based on the combination of high index of clinical suspicion, familiarity with the standard anatomy and its variations, the use of the appropriate radiological investigations and surgical intervention in a timely manner.

Bouveret syndrome-a rare form of gastric outlet obstruction

Bouveret syndrome is a rare form of gastric outlet obstruction. It is typically diagnosed in frail elderly patients with protracted biliary disease. Thus, it has disproportionally high rates of morbidity and mortality. A 90-year-old man presented to our tertiary hospital with acute abdominal pain and symptoms of bowel obstruction. He was diagnosed with Bouveret syndrome on abdominal computed tomography and required judicious resuscitation and an emergency laparotomy. This article highlights the key features of Bouveret syndrome, and reviews the current diagnostic modalities as well as the contemporary treatment paradigm.

Endoscopic lithotripsy for Bouveret syndrome complicated by small bowel obstruction secondary to gallstone fragments

Bouveret syndrome is a rare complication of cholecystitis, in which impaction of a gallstone creates a cholecystoduodenal fistula leading to gastric outlet obstruction. We report a case of a 90-year-old female who presented with nausea and vomiting on a background of previous necrotic cholecystitis managed conservatively. Computed tomography of the abdomen demonstrated a large gallstone impacted in the third part of the duodenum leading to gastric outlet obstruction. Given her frailty, the patient underwent endoscopy to relieve the obstruction; however, complete retrieval of the gallstone fragments after lithotripsy was not possible. She subsequently developed distal gallstone ileus due to migration of the gallstone fragments and underwent laparotomy, enterotomy and retrieval of the fragments. This case highlights the dilemma of managing elderly patients with Bouveret syndrome with open or endoscopic surgery and the importance of retrieving all gallstone fragments after lithotripsy to avoid iatrogenic complications, such as gallstone ileus.

Bouveret Syndrome: A Rare Form of Gallstone Ileus

Bouveret’s syndrome is a rare variant of gallstone ileus characterized by a gastric outlet obstruction due to the impaction of a gallstone lodged in the duodenum, resulting from a cholecystoduodenal fistula. It accounts for only one to three percent of cases of gallstone ileus. We examine a case of Bouveret syndrome in an elderly Japanese female who presented with vomiting and decreased oral intake. Subsequent imaging found a gallstone ileus due to a bilioduodenal fistula. She underwent exploratory laparotomy enterolithotomy which found a large black gallstone located in the small bowel and confirmed the presence of the fistula. Despite its relative rarity, Bouveret syndrome carries a high risk of morbidity and mortality.

Gallstone ileus: a rare type of intestinal obstruction in Ghana

Gallstone ileus is an uncommon cause of intestinal obstruction in Ghana. A patient with gallstone ileus that was diagnosed intra-operatively after being treated conservatively as adhesive small bowel obstruction for ten days is reported to highlight the importance of the clinical information in this condition. A 60-year-old Chinese male with recurrent intestinal obstruction who was initially being managed at a primary healthcare facility was subsequently referred to a tertiary hospital on account of computer tomography diagnosis of an intraluminal object obstructing the bowel. He had hypokalaemia that was corrected before surgery. Intra-operatively, a 4.5cm in diameter gallstone was removed from the terminal ileum. Gallstone ileus is rare in Ghana. A high index of suspicion is required to avoid a delay in diagnosis due to the low incidence of cholelithiasis in Ghana.

Gallstone ileus after recent cholecystectomy. Case report and review of the literature

INTRODUCTION AND IMPORTANCE

Gallstone ileus in cholecystectomized patients is very infrequent and when it happens shortly after surgery is even rarer. We report the case of a patient who presented Gallstone ileus few days after open cholecystectomy which has not been reported before in literature.

CASE PRESENTATION

A 52-year-old male with a history of recent open cholecystectomy was referred to our center due to a presumable surgical complication. During his hospitalization while trying to restart the oral route he presented abdominal pain and nausea. He evolved toward a bowel obstruction. We suspected gallstone ileus based on medical history as well as preoperative image study. We confirmed the diagnostic using a Computed Tomography. Surgical management was performed and a large gallstone was extracted from the bowel. The patient progressed favorably and was discharged. He was asymptomatic during the follow-up.

CLINICAL DISCUSSION

Cholecystectomized patients who have been reported with Gallstone ileus demonstrate different pathophysiological mechanisms or extraordinary presentations. This case describes a unique presentation illustrating relevant aspects of this pathology such as showing that acute cholecystitis can be its clinical manifestation or that it could happen after a cholecystoenteric fistula is found during a cholecystectomy.

CONCLUSION

Gallstone ileus in cholecystectomized patients is very rare. Clinical suspicion remains the cornerstone of diagnosis.

Bouveret syndrome: a rare form of gallstone ileus

A 57-year-old woman presented with a 5-day history of worsening right upper quadrant pain, bilious emesis and approximately 20 pounds of weight loss. The patient was afebrile, without jaundice and had mild tenderness in her right upper quadrant. She noted an incidental finding of asymptomatic cholelithiasis on imaging 4 years earlier. An abdominal radiograph revealed pneumobilia and a large ectopic calculus. An abdominal CT scan confirmed pneumobilia, a large concretion completely obstructing the third portion of the duodenum and a soft tissue communication between the gallbladder and proximal duodenum. She was brought to the operating room for definitive treatment and had the obstructing gallstone removed via a transverse duodenotomy. Bouveret syndrome is a rare cause of small bowel obstruction that requires a high index of suspicion for diagnosis. It should be considered in older patients with clinical evidence of gastric or duodenal obstruction, particularly with a history of cholelithiasis.

Bouveret syndrome masquerading as a gastric mass-unmasked with endoscopic luminal laser lithotripsy: A case report

BACKGROUND

Bouveret syndrome, also known as gallstone ileus, is a rare form of gastric outlet obstruction accounting for 1%-3% of cases. This condition is most often reported in females. The diagnosis can be challenging and is often missed due to atypical presentations, which occasionally mimic gastric outlet obstruction symptoms such as nausea, vomiting, loss of appetite and hematemesis. The symptoms vary with stone size. Larger stones are managed with a surgical approach, but this carries increased morbidity and mortality. Over the past decade, the endoscopic approach has emerged as an alternative mode of treatment, but it is generally unsuccessful in the management of larger-sized stones. A literature review revealed cases of successful endoscopic treatment requiring multiple sessions for stone sizes measuring up to about 4.5 cm. Here we present a unique case of an elderly patient with Bouveret syndrome with a 5 cm stone mimicking a gastric mass and causing gastric outlet obstruction, who was successfully managed in a single session using a complete endoscopic approach with laser lithotripsy.

CASE SUMMARY

An 85-year-old female patient presented with 1-month history of intermittent abdominal pain, vomiting, decreased appetite and weight loss. An abdominal computed tomography showed a 4.5 cm × 4.7 cm partially calcified mass at the gastric pylorus causing gastric outlet obstruction. Endoscopy showed an ulcerated fistulous opening and a large 5 cm impacted gallstone in the duodenal bulb. Endoscopic nets and baskets were used in an attempt to remove the stone, but this approach was unsuccessful. Given her advanced age, poor physical condition and underlying comorbidities, she was deemed to be high-risk for surgery. Thus, a minimally invasive approach using endoscopic laser lithotripsy was attempted and successfully treated the stone. Post-procedure, the patient experienced complete resolution of her symptoms with no complications and was able to tolerate her diet. She was subsequently discharged home at 48 h, with an uneventful recovery.

CONCLUSION

In our paper we describe Bouveret syndrome and highlight its management with a novel endoscopic approach of laser lithotripsy in addition to various other endoscopic approaches available to date and its success rates.

A Rare Case of Gallstone Ileus: Bouveret Syndrome Presenting with Concurrent Gallstone Coleus

Background

Bouveret syndrome and gallstone coleus are two rare subsets of gallstone ileus. Bouveret syndrome involves a gastric outlet obstruction, whereas gallstone coleus involves an obstruction of the large intestine. Both of the conditions are caused by gallstones, which migrated from the gallbladder via the fistulae. Due to its rarity, only few cases were reported for each condition. The current case describes an even rarer case of Bouveret syndrome and gallstone coleus presenting together. The case report will hopefully provide better understanding of the disease presentation and hence, lead to early diagnosis and management.

Case

Ms. B is an 86-year-old woman of Italian background who presented to our emergency department with worsening symptoms of bowel obstruction. Her past clinical history included Kaposi sarcoma, hypertension, osteoarthritis, and vitamin D deficiency with surgical history including caesarean section and tonsillectomy. On her imaging, she had two large gallstones, one in the proximal duodenum and one in the distal colon. It also showed gastric dilatation and gas in the gall bladder. She was subsequently diagnosed with Bouveret syndrome with concurrent gallstone coleus. The laparotomy revealed two points of gallstone obstruction at the first part of the duodenum and at the distal sigmoid colon. Her postoperative recovery was uncomplicated. She was discharged to the care of her family and followed up in the general surgery clinic.

Conclusion

The current case report describes a unique presentation of Bouveret syndrome where an additional gallstone was found simultaneously in the sigmoid colon causing the obstruction. By introducing this novel case of having two different subsets of gallstone ileus simultaneously, there will be a better understanding of both conditions and hopefully improve our scope of practice.

Duodenal Obstruction Due to Giant Gallstone: A Case Report

Background

Duodenal obstruction due to a gallstone, also known as Bouveret’s syndrome, is one type of gallstone ileus. This is a rare complication of cholelithiasis. Among gallstone ileus cases, duodenal obstruction is alsorare. Apart from rareness, diagnosis is challenging due to unspecific clinical manifestation. Treatment options have benefits and drawbacks with each as well. Therefore, setting an appropriate option in a certain patient is an important issue.

Case Report

An 85-year-old woman presented clinically with a gastric outlet obstruction. Upper gastrointestinal (GI) endoscopy was attempted but endoscopic exploration was limited because of duodenum filled by fluid. Rigler’s triad was detected on abdominal enhanced CT scan: duodenal obstruction, ectopic gallstone within duodenum lumen, pneumobilia. The stone was very large (9 cm long). The diagnosis was duodenal obstruction due to giant gallstone and cholecysto-duodenum fistula. The patient was treated with a radical one-stage procedure: fistulotomy for gallstone removal, cholecystectomy, side-to-side Roux-en-Y duodenojejunostomy. There were no complications related to surgery during the follow-up period.

Conclusion

Surgery plays an important role in management of duodenal obstruction due to a gallstone, especially a large and impacted stone. Radical one-stage surgery is one of the feasible, safe, and efficient procedures in selected patients.

Complicating factors in the management of advanced Bouveret syndrome in frail and medically complex patients: Case report and discussion of pathophysiology

•

Bouveret’s syndrome results from biliary stones from cholecysto-duodenal fistula.

•

Gastric outlet obstruction from duodenal stones has high morbidity and mortality.

•

Duodenal gallstones may grow over time, increasing risks of management.

•

Delay in diagnosis and stone extraction may result in needing higher risk surgery.

•

Tertiary referral of at-risk elderly or frail patients may improve outcomes.

Introduction

Bouveret Syndrome is a rare but important variant of gallstone ileus with high potential for morbidity and mortality. Bouveret syndrome is a complication of gallstone disease resulting from chronic inflammation and subsequent fistulization between the gallbladder and duodenum or stomach with subsequent impaction of the stone in the proximal GI tract. Here we present a case in an elderly man with moderate medical comorbidities.

Presentation of case

An elderly man presented to the hospital with symptoms of gastrointestinal obstruction. Upon further diagnostic work-up, he was noted to have a 5.8 cm gallstone impacted in his proximal GI tract and thus diagnosed with a rare variant of gallstone ileus—Bouveret syndrome.

Discussion

The therapeutic goal in approaching Bouveret syndrome is removal of the stone and improvement in obstruction and cholangitis. This may be accomplished with surgery or endoscopic therapy—although this may be less effective. Bouveret syndrome may have high morbidity.

Conclusion

Bouveret syndrome is a rare but potentially serious syndrome that should be managed accordingly. It should remain on the differential diagnosis of an elderly patient presenting with gastrointestinal obstructions, particularly if there is a history of gallstone disease and concern for proximal GI obstruction.

Bouveret Syndrome: A Rare Case of Gallstone Ileus Further Complicated by Stone Migration

Bouveret syndrome is a rare cause of gastric outlet obstruction due to gallstone impaction in the pylorus or proximal duodenum. This paper reports a case of Bouveret syndrome in a 66-year-old male patient in whom pre-operative investigations revealed a gallstone within the distal stomach, but spontaneous migration of the stone resulted in intraoperative difficulty requiring further surgical exploration than originally anticipated.

Bouveret Syndrome: A Rare Case of Instance and Treatment in a Younger Patient

Bouveret syndrome, a specific form of gallstone ileus, is the obstruction of the gastric outlet by a gallstone, which can enter the duodenum through a fistula. While the average age of individuals with Bouveret syndrome is 74 years, our patient was 42 years of age at the time of operation, significantly younger than the average patient afflicted with this condition. In the treatment of our patient's condition, the operation conducted entailed a partial duodenectomy, gastrojejunostomy, cholecystectomy, common bile duct exploration, extraction of bile duct stones, and insertion of a t-tube in the bile duct. The patient was found to be in healthy condition upon check-up six months after the operation. The outcome of our case suggests that younger Bouveret patients can safely undergo multiple surgical procedures in the treatment of Bouveret syndrome. Our case also suggests that a cholecystectomy and the removal of the obstructing gallstone can both be carried out within one operation, although coupling these two procedures in one operation might be riskier for patients within the normal age range of Bouveret syndrome. We also suggest that fistula repair be carried out for younger Bouveret patients in particular and that the patient be subjected to a CT scan in the diagnosis of Bouveret syndrome when this condition is suspected.

A case report and review of the literature of Bouveret syndrome

Bouveret syndrome is a rare variant of gallstone ileus causing gastric outlet obstruction. It results from the formation of either a cholecystoduodenal or a cholecystogastric fistula and subsequent migration of gallstone into the duodenum or pylorus of stomach, causing obstruction. The first case was reported by Leon Bouveret in 1896. We report a case illustrating the rarity and severity of this condition, together with a review of the literature of the different methods of endoscopic and surgical treatment.

Bouveret syndrome: A case report

BACKGROUND

Bouveret syndrome is a rare complication of cholelithiasis, with only 315 cases reported in the literature between 1967 and 2016. Delay in diagnosis is associated with a high mortality rate. Diagnosis is based upon clinical manifestations, gastroscopy, and imaging studies such as abdominal computed tomography and magnetic resonance cholan-giopancreatography. Endoscopic stone extraction or lithotripsy is the preferred choice for treatment as it is safe and minimally invasive with few complications. However, if endoscopy fails, surgery is required.

CASE SUMMARY

A 61-year-old female patient presented with recurrent epigastric pain for more than 6 mo. On endoscopy, a large amount of food residue was present in the stomach with multiple stones and ulcers in the antro-pyloric region. Based on these findings, a diagnosis of gastrolithiasis was made. However, computed tomography of the abdomen revealed the correct diagnosis of Bouveret syndrome. Initially, endoscopic treatment was attempted but it failed. Later, she was successfully managed by cholecystectomy with duodenal stone extraction and fistula repair (one-step method). At the last follow-up 6 mo after surgery, the patient was symptom-free.

CONCLUSION

Bouveret syndrome is a rare complication of gallstones that requires prompt endoscopic or surgical treatment to prevent mortality.

Fluoroscopic findings in Bouveret syndrome

Bouveret syndrome occurs when a gallstone passes into the duodenum from a fistulous communication between the gallbladder and the duodenum. This is an uncommon cause of abdominal pain which is often diagnosed following surgery. Most imaging findings of Bouveret syndrome are limited to computed tomography. Shown here are fluoroscopic images of the upper gastrointestinal system in this uncommon disorder.

The curious case of biliary emesis and bowel obstruction from Bouveret syndrome

Bouveret syndrome is a rare complication of biliary lithiasis. This sequela is caused by the passage of the gallstone via a bilioenteric fistula, resulting in an impacted gallstone in the duodenum or stomach. The common presentation of non-specific symptoms contributes to the diagnostic uncertainty and delay, which is strongly associated with adverse outcomes. We report an uncomplicated stone extraction via open gastrotomy in an elderly man afflicted with bowel obstruction and biliary vomit secondary to Bouveret syndrome.

Bouveret's Syndrome

Bouveret syndrome is a very rare form of gastric outlet obstruction following the passage of a gallstone from the gallbladder to the duodenum or pylorus through a bilioenteric fistula. We present a unique case of a 78-year-old male complaining of right upper quadrant abdominal pain and who was found to have a gallstone in the proximal duodenum along with pneumobilia and cholecysto-duodenal fistula suggestive of Bouveret’s syndrome.

Cholecystoduodenal fistula caused by aggressive mucinous gallbladder carcinoma with a porcelain gallbladder

Cholecystoduodenal fistula secondary to gallbladder carcinoma (GBC) is extremely rare and develops when the tumor penetrates into the adjacent duodenum. A porcelain gallbladder is also a very rare entity that involves the calcification of the gallbladder wall and can be associated with the development of GBC. Herein, we report an unusual case of a patient with cholecystoduodenal fistula, which has been caused by aggressive mucinous gallbladder carcinoma with a porcelain gallbladder. A 68-year-old man was referred to our department due to significant accumulation near the neck of the gallbladder detected by FDG positron emission tomography/computed tomography (PET/CT), which was performed as a check-up of postpneumonectomy for lung cancer. Abdominal contrast CT and magnetic resonance imaging revealed porcelain-like circumferential calcification of the gallbladder wall and a mass in the region detected by FDG PET/CT. Furthermore, upper endoscopy revealed a submucosal tumor with apical ulceration in the posterior wall of the duodenal bulb. Histopathological examination of its biopsy specimen rendered a diagnosis of adenocarcinoma. The patient was preoperatively diagnosed with either gallbladder cancer or duodenal cancer, and subtotal stomach-preserving pancreatoduodenectomy and radical cholecystectomy with gallbladder bed resection were performed. The resected gallbladder revealed a porcelain gallbladder, which formed the cholecystoduodenal fistula. These specimens were histopathologically diagnosed as mucinous adenocarcinoma of the gallbladder with an abundant mucin production.

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

Bouveret's Syndrome: Literature Review

It was in 1896 that Bouveret’s syndrome acquired its name after the French physician Leon Bouveret, who published two case reports in Revue de Medecin. Bouveret’s syndrome describes gastric outlet obstruction secondary to an impacted gallstone. The gallstone reaches the small bowel through a bilioenteric fistula as a consequence of chronic inflammation and adherence between the biliary system and the bowels which increase the intraluminal pressure and leads to secondary wall ischemia and wall perforation with gallstone passage into the bowel. Bouveret’s syndrome’s prevalence is highest among elderly women. Despite the rarity of Bouveret’s syndrome, it can cause notable morbidity and mortality rates. We underwent a review of literature about Bouveret syndrome to increase awareness of its occurrence and potentially life-threatening complications.

Bouveret syndrome: current management strategies

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 of the duodenum: an unexpected presentation of Bouveret's syndrome

This report describes a patient who presented with a large gallstone obstructing the duodenal bulb, with the chief complaint of acute on chronic abdominal pain. Classically, this is known as Bouveret's syndrome or a gallstone ileus of the duodenum. Our patient's current health status presented a challenge, with the presence of several comorbidities, particularly a large abdominal aortic aneurism. We chose an open procedure for this reason. The stone was removed through a laparotomy, and the cholecystoduodenal fistula that the stone used to pass into the small bowel was repaired. With our patient's future medical needs in mind, only the necessary interventions were performed to regain functionality of the bowel. This came in the form of a diverting gastrojejunostomy, with a distal jejunostomy and feeding tube inserted. The patient tolerated the procedure well, only remaining intubated postoperative due to her chronic obstructive pulmonary disease (COPD). She achieved a complete recovery and transitioned home.

Successful Endoscopic Treatment of Bouveret Syndrome in a Patient with Choledochoduodenal Fistula Complicating Duodenal Ulcer

Introduction

Cholecystoduodenal fistulas represent the most common type of bilioenteric fistulas while choledochoduodenal fistulas account for only 1–25% of cases. Bilioenteric fistula cases are associated with cholelithiasis and are rarely associated with duodenal peptic ulcers. Here we present the first case of Bouveret syndrome secondary to choledochoduodenal fistula complicating peptic duodenal ulcer managed successfully via endoscopic mechanical lithotripsy.

Case

86-year-old male with a medical history significant for coronary artery disease and stage 3 colorectal cancer status after resection and chemoradiation presented with intractable sharp abdominal pain worse postprandially for one week in duration, associated with early satiety, anorexia, and 5 lbs weight loss in one week. CT abdomen showed possible choledochoduodenal fistula and a distended stomach. An esophagogastroduodenoscopy (EGD) was performed revealing a large 2.5–3 cm stone lodged in the duodenal bulb at the base of duodenal ulcer with a fistula opening beneath it. The stone was extracted in 2 pieces via mechanical lithotripsy. Endoscopic ultrasound of the CBD revealed Rigler's triad.

Conclusion

Bouveret syndrome is mostly associated with cholecystoduodenal fistula and has high mortality and morbidity due to underlying comorbid conditions and elderly age. Patients are not always fit for surgical management, and endoscopic management is not always successful.

Bouveret's syndrome-a rare form of gallstone ileus causing death: appearance on post-mortem CT and MRI

Bouveret’s syndrome is a very rare cause of gastric outlet obstruction occurring as a complication of cholelithiasis with cholecystogastric or cholecystoenteric fistula. Without timely diagnosis and intervention Bouveret’s syndrome can be associated with a high rate of morbidity and mortality, with common causes of death including metabolic derangements, aspiration pneumonia and post-operative complications. We report the case of a 67-year-old female found dead in her home with regurgitated gastric contents filling her mouth and nasal cavity. Post-mortem CT and MRI imaging was performed and subsequently revealed a fistulous tract between the gallbladder and proximal duodenum, with impaction of a large obstructing stone in the mid-portion of the duodenum. Post-mortem imaging also revealed findings of gastric outlet obstruction, which was presumed to be a primary contributor to her cause of death.

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.

Gallstone ileus with choledochoduodenal fistulas: A case report and literature review

Gallstone ileus (GI) with choledochoduodenal fistulas and multiple sites of intestinal obstruction are uncommon. Early diagnosis and appropriate surgery are crucial to reduce morbidity and mortality of GI. Computed tomography plays an important role in making early, accurate diagnosis, and laparoscopy-assisted surgery is helpful to optimizing surgical treatment and early recovery. This paper presents such a case and performed a literature review to improve the awareness of the approach for the management of GI.

A rare presentation of gastric outlet obstruction (GOO) - The Bouveret's syndrome

INTRODUCTION

Bouveret's Syndrome is a rare cause of Gastric outlet obstruction (GOO) caused by a gall stone which has migrated into the duodenal bulb from a bilioduodenal fistula. It is an uncommon condition and only a few cases have been reported in the medical literature till to date.

PRESENTATION OF CASE

We report a case of a 45 year old woman who presented to us with recurrent pain in the upper abdomen for the last 8 years, and that progressed to develop symptoms of gastric outlet obstruction. An upper gastrointestinal endoscopy revealed duodenal ulceration with a stony hard lesion in the first part of duodenum. An contrast enhanced computed tomography (CECT) scan of the abdomen performed later confirmed the presence of cholecystoduodenal fistula and a gall-stone in proximal jejunum.

DISCUSSION

Bouveret's syndrome is a case of gastric outlet obstruction caused by the impaction of a large gall stone in the duodenum as a result of a cholecystoduodenal fistula. It constitutes 1-3% of cases of gall stone ileus which in turn complicates only 0.3-4% cases of cholelithisasis. Bouveret's syndrome is managed surgically.

CONCLUSION

Bouveret's syndrome being an uncommon condition may pose a difficulty in diagnosis and dilemma in managing such patients. An awareness is hence essential.

Gallstone ileus obstructing within an incarcerated lumbar hernia: an unusual presentation of a rare diagnosis

We describe an unusual case of a 74-year-old woman who presented with signs and symptoms of small-bowel obstruction and a clinically appreciable, irreducible, left-sided lumbar hernia associated with previous iliac crest bone graft harvesting. Palpation of the hernia demonstrated a small, firm mass within the loops of herniated bowel. CT scanning recognised an intraluminal gallstone at the transition point, establishing the diagnosis of gallstone ileus within an incarcerated lumbar hernia. The proposed explanatory mechanism is that of a gallstone migrating into an easily reducible hernia containing small bowel causing obstruction at the hernia neck by a ball-valve mechanism, resulting in proximal bowel dilation and thus hernia incarceration; it remains unclear when the stone entered the hernia, and whether it enlarged in situ or prior to entering the enteral tract. This is only the second reported instance in the literature of an intraluminal gallstone causing hernia incarceration.

Bouveret's Syndrome: An Overlooked Diagnosis. A Case Report and Review of Literature

Bouveret's syndrome is a rare cause of gastric outlet obstruction. Its diagnosis is often delayed or overlooked. It is characterized by the passage of a large gall bladder stone through a bilio-duodenal fistula, which becomes lodged in the duodenum causing duodenal obstruction. We report the case of a 70-year-old male with a history suggestive of gall bladder disease over a 1-year period. The diagnosis was confirmed by ultrasound, which showed a single large gall bladder stone and the patient was planned for elective laparoscopic cholecystectomy. One week prior to the elective surgery he presented with upper gastrointestinal bleeding for which he was admitted, diagnosed by a gastroenterologist as bleeding duodenal ulcer and treated by local epinephrine injection and blood transfusion. One week later he presented with a picture of acute gastric outlet obstruction, which proved by endoscopy to be due to a large stone impacted in the duodenum. Endoscopic management failed and the stone was managed by open surgery. The patient made a good postoperative recovery and for the last year he has remained free of symptoms.
