Management of Dyspepsia and Referral Criteria for Suspected Cancer

Dyspepsia is a common condition that can be managed through a stepwise approach. The first step is to review medications that may be causing dyspepsia and provide lifestyle advice. If symptoms persist, a full-dose proton pump inhibitor or a ‘test and treat’ approach for H. pylori can be tried for one month. If symptoms still persist, the alternative approach should be attempted.

For patients who meet referral criteria for suspected cancer, urgent referral for an endoscopy within two weeks is necessary. This includes patients with dysphagia, an upper abdominal mass consistent with stomach cancer, and patients aged 55 years or older with weight loss and upper abdominal pain, reflux, or dyspepsia. Non-urgent referral is recommended for patients with haematemesis and patients aged 55 years or older with treatment-resistant dyspepsia, upper abdominal pain with low haemoglobin levels, or raised platelet count with symptoms such as nausea, vomiting, weight loss, reflux, dyspepsia, or upper abdominal pain.

Testing for H. pylori infection can be done through a carbon-13 urea breath test, stool antigen test, or laboratory-based serology. If symptoms have resolved following a ‘test and treat’ approach, there is no need to check for H. pylori eradication. However, if repeat testing is required, a carbon-13 urea breath test should be used.

Weight loss with dyspepsia is a concerning symptom in individuals over 55 years old and warrants urgent referral for an endoscopy to identify any underlying pathology. Helicobacter pylori testing may not be the most appropriate option in this case. Symptomatic relief can be provided with proton-pump inhibitors or ranitidine, but they do not rule out any underlying pathology.

Hypomagnesaemia, a condition that can lead to muscle weakness, is a potential side effect of long-term use of proton pump inhibitors. Although rare, this effect may occur after 3 months or more commonly after 1 year of therapy. However, clarithromycin, ramipril, amlodipine, and amoxicillin are not associated with hypomagnesaemia.

Understanding Proton Pump Inhibitors

Proton pump inhibitors (PPIs) are medications that work by blocking the H+/K+ ATPase in the stomach parietal cells. This action is irreversible and helps to reduce the amount of acid produced in the stomach. Examples of PPIs include omeprazole and lansoprazole.

Despite their effectiveness in treating conditions such as gastroesophageal reflux disease (GERD) and peptic ulcers, PPIs can have adverse effects. These include hyponatremia and hypomagnesemia, which are low levels of sodium and magnesium in the blood, respectively. Prolonged use of PPIs can also increase the risk of osteoporosis, leading to an increased risk of fractures. Additionally, there is a potential for microscopic colitis and an increased risk of C. difficile infections.

It is important to weigh the benefits and risks of PPIs with your healthcare provider and to use them only as directed. Regular monitoring of electrolyte levels and bone density may also be necessary for those on long-term PPI therapy.

Importance of Stopping Acid Suppression Medication Prior to Endoscopy

In urgent cases where endoscopy is required, it is recommended to stop acid suppression medication for at least two weeks before the procedure. This is because acid suppression medication can hide serious underlying conditions that need to be addressed. However, there may be situations where stopping the medication is difficult due to symptoms, and clinical judgement must be used.

For instance, if a patient experiences unintentional weight loss, it is a red flag symptom for upper GI malignancy, and urgent referral for endoscopy is necessary. In such cases, the benefits of stopping acid suppression medication should be weighed against the potential risks of continuing it. Ultimately, the decision should be made based on the patient’s individual circumstances and the urgency of the situation. Proper evaluation and management can help ensure the best possible outcome for the patient.

Odynophagia is a worrying symptom that can be indicative of oesophageal cancer. According to NICE guidelines, individuals with dysphagia or those aged 55 and over with weight loss and upper abdominal pain, reflux, or dyspepsia should be urgently referred for direct access upper gastrointestinal endoscopy within 2 weeks to assess for oesophageal cancer.

In Albert’s case, as he is presenting with dysphagia and odynophagia, urgent upper GI endoscopy within 2 weeks is the appropriate course of action. While blood tests such as FBC and CRP may provide some clues towards a cancer diagnosis, the priority is to rule out malignancy through endoscopy.

Referral to speech and language therapy would not be appropriate at this stage, as the focus is on diagnosing or ruling out cancer. Prescribing analgesia may provide some relief for odynophagia, but it would not address the underlying issue of dysphagia or the need to investigate for malignancy.

While a barium swallow may be useful in investigating dysphagia and odynophagia, urgent upper GI endoscopy is the most appropriate investigation to assess for oesophageal cancer.

Oesophageal Cancer: Types, Risk Factors, Features, Diagnosis, and Treatment

Oesophageal cancer used to be mostly squamous cell carcinoma, but adenocarcinoma is now becoming more common, especially in patients with a history of gastro-oesophageal reflux disease (GORD) or Barrett’s. Adenocarcinoma is usually located near the gastroesophageal junction, while squamous cell tumours are found in the upper two-thirds of the oesophagus. The most common presenting symptom is dysphagia, followed by anorexia and weight loss, vomiting, and other possible features such as odynophagia, hoarseness, melaena, and cough.

To diagnose oesophageal cancer, upper GI endoscopy with biopsy is used, and endoscopic ultrasound is preferred for locoregional staging. CT scanning of the chest, abdomen, and pelvis is used for initial staging, and FDG-PET CT may be used for detecting occult metastases if metastases are not seen on the initial staging CT scans. Laparoscopy is sometimes performed to detect occult peritoneal disease.

Operable disease is best managed by surgical resection, with the most common procedure being an Ivor-Lewis type oesophagectomy. However, the biggest surgical challenge is anastomotic leak, which can result in mediastinitis. In addition to surgical resection, many patients will be treated with adjuvant chemotherapy.

Understanding Gastric Ulcers and Their Symptoms

Gastric ulcers are a common condition that can cause a range of symptoms. One of the most typical symptoms is abdominal pain, which can be described as a burning or gnawing sensation. Other symptoms may include nausea, vomiting, and loss of appetite.

It’s important to note that the symptoms of a gastric ulcer can be similar to those of other conditions, such as duodenal ulcers, gallstones, gastric carcinoma, and hiatus hernia. However, there are some key differences to look out for.

In duodenal ulcers, for example, the pain is usually delayed after eating and can be relieved by food. Gallstones, on the other hand, typically cause pain in the right upper quadrant and do not usually result in melaena (dark, tarry stools).

Gastric carcinoma should be considered in anyone with abdominal pain and weight loss, but gastric ulcer is more likely in younger patients without anorexia. Hiatus hernia, meanwhile, is often associated with heartburn and reflux.

If you are experiencing symptoms of a gastric ulcer, it’s important to seek medical attention. Your doctor can perform tests to determine the cause of your symptoms and recommend appropriate treatment.

Helicobacter pylori: A Bacteria Associated with Gastrointestinal Problems

Helicobacter pylori is a type of Gram-negative bacteria that is commonly associated with various gastrointestinal problems, particularly peptic ulcer disease. This bacterium has two primary mechanisms that allow it to survive in the acidic environment of the stomach. Firstly, it uses its flagella to move away from low pH areas and burrow into the mucous lining to reach the epithelial cells underneath. Secondly, it secretes urease, which converts urea to NH3, leading to an alkalinization of the acidic environment and increased bacterial survival.

The pathogenesis mechanism of Helicobacter pylori involves the release of bacterial cytotoxins, such as the CagA toxin, which can disrupt the gastric mucosa. This bacterium is associated with several gastrointestinal problems, including peptic ulcer disease, gastric cancer, B cell lymphoma of MALT tissue, and atrophic gastritis. However, its role in gastro-oesophageal reflux disease (GORD) is unclear, and there is currently no role for the eradication of Helicobacter pylori in GORD.

The management of Helicobacter pylori infection involves a 7-day course of treatment with a proton pump inhibitor, amoxicillin, and either clarithromycin or metronidazole. For patients who are allergic to penicillin, a proton pump inhibitor, metronidazole, and clarithromycin are used instead.

Alarm Symptoms of Foregut Malignancy

The presence of alarm symptoms in patients over 55 years old, such as weight loss, bleeding, dysphagia, vomiting, blood loss, and a mass, are indicative of a malignancy of the foregut. It is crucial to refer these patients for urgent endoscopy, especially if dysphagia is a new onset symptom.

However, it is unfortunate that patients with alarm symptoms are often treated with PPIs instead of being referred for further evaluation. Although PPIs may provide temporary relief, they only delay the diagnosis of the underlying tumor. Therefore, it is important to recognize the significance of alarm symptoms and promptly refer patients for appropriate diagnostic testing.

As per the revised NICE guidelines of 2015, there is no need for an immediate endoscopy referral for her. However, if she fails to respond to treatment, a non-urgent referral would be advisable.

Management of Dyspepsia and Referral Criteria for Suspected Cancer

Dyspepsia is a common condition that can be managed through a stepwise approach. The first step is to review medications that may be causing dyspepsia and provide lifestyle advice. If symptoms persist, a full-dose proton pump inhibitor or a ‘test and treat’ approach for H. pylori can be tried for one month.

Non-urgent referral is recommended for patients with haematemesis and patients aged 55 years or older with treatment-resistant dyspepsia, upper abdominal pain with low haemoglobin levels, or raised platelet count with symptoms such as nausea, vomiting, weight loss, reflux, dyspepsia, or upper abdominal pain.

Testing for H. pylori infection can be done through a carbon-13 urea breath test, stool antigen test, or laboratory-based serology. If symptoms have resolved following a ‘test and treat’ approach, there is no need to check for H. pylori eradication. However, if repeat testing is required, a carbon-13 urea breath test should be used.

Hepatitis E and D: A Comparison

Hepatitis E is a self-limiting illness that follows a similar course to hepatitis A. However, fulminant disease can occur in a small percentage of cases. This type of hepatitis is most commonly found in developing countries and is transmitted through contaminated drinking water. While person-to-person contact transmission is rare, maternal-neonatal transmission can occur, with pregnant women being at the highest risk of developing fulminant hepatitis. Management of hepatitis E is supportive, and there are no chronic cases except in immunocompromised individuals.

On the other hand, hepatitis D requires co-infection with hepatitis B to cause inflammation. Co-infection with hepatitis D increases the likelihood of hepatitis B progressing to chronic disease and cirrhosis. Hepatitis D is most commonly found in Mediterranean countries, parts of Eastern Europe, the Middle East, Africa, and South America.
