What is Bouveret syndrome? Treatment regimen and notes

What is Bouveret syndrome?

Bouveret syndrome is a rare and complex medical condition that primarily affects the gastrointestinal system.

This condition is a type of gallstone ileus, which occurs when a large gallstone passes through a fistula (an abnormal passage) formed between the gallbladder and the small intestine. This passage allows the gallstone to travel into the intestines, where it can cause significant blockages and complications.

Normally, the gallstone travels from the gallbladder into the duodenum, the first part of the small intestine. However, the most striking feature of this syndrome is the involvement of a gastrocolic fistula, a direct connection between the gallbladder and the duodenum.

This abnormal communication allows the gallstone to enter the duodenum, leading to symptoms like nausea, vomiting, and abdominal pain. The obstruction caused by the gallstone can result in complications such as bowel perforation, sepsis, and shock.

Bouveret syndrome is often difficult to diagnose due to its rarity and the overlap of symptoms with other digestive disorders.

The primary cause of Bouveret syndrome is the formation of a gallstone that obstructs the gastrointestinal tract. Gallstones are hardened deposits of digestive fluid, which can form in the gallbladder due to an imbalance in the substances that make up bile. Factors like age, gender or obesity may increase the risk of the syndrome.

Treatment regimen for a Bouveret syndrome patient

The main goal in treating Bouveret’s syndrome is to remove the gallstone that’s causing the blockage. Treatment options include non-surgical methods like endoscopy or surgical options, which can be done through either open surgery or laparoscopic surgery.

Endoscopy

Endoscopy is often the first choice for treating Bouveret’s syndrome because it is less invasive. This method works best for smaller stones, but it’s generally less effective than surgery.

Lithotripsy

Lithotripsy is a non-surgical method where the gallstone is broken up and then removed using tools like nets or baskets.

Electrohydraulic lithotripsy is used for larger stones, and high-energy shock waves break the stones into smaller pieces for easier removal. This method works well for stones larger than 2.5 cm, but it can cause problems like bleeding or injury to the bowel if not done carefully.

Laser lithotripsy uses focused energy to break the stone apart, causing less damage to surrounding tissue. It allows the doctor to control the laser precisely, making it a safe option for treating gallstones.

Surgery

Surgery used to be the main treatment for Bouveret’s syndrome, but it’s now usually only recommended if other methods, like endoscopy, don’t work. This treatment is not often recommended for older patients because it carries higher risks.

In some cases, if the gallstones are causing serious stomach health problems, doctors may suggest removing the gallbladder. If there is a fistula, it may be repaired during the same procedure.

How to avoid Bouveret syndrome

While Bouveret syndrome itself cannot always be completely avoided, many of the underlying causes, particularly gallstones, can be prevented through lifestyle changes.

• Maintain a healthy diet: Eating a balanced, fiber-rich diet can help reduce the risk of gallstones by promoting healthy bile production and digestion. Some tips you can easily follow are eating more fruits, reducing fatty foods and drinking enough water.
• Stay physically active: Regular exercise is key to maintaining a healthy weight and preventing obesity, a major risk factor for gallstones. No need for heavy exercises, you just need to spend at least 30 minutes a day walking, swimming, or cycling.
• Control your weight: Obesity and being overweight can increase your chances of developing gallstones. A gradual, sustainable weight loss program can help reduce your risk. It’s important to avoid extreme or rapid weight loss, as this can actually increase the likelihood of gallstone formation.
• Regular medical check-ups: If you have any risk factors for gallstones, such as a family history, age, or chronic medical conditions, consider undergoing regular screenings for gallstones. Early detection can help prevent complications like Bouveret syndrome.

Bouveret syndrome is a rare but serious condition that requires prompt treatment to avoid complications. Preventive measures like a healthy diet and regular exercise can help reduce the risk of developing gallstones. However, if you experience symptoms of gallstones or gastrointestinal distress, seek medical advice promptly.
