Understanding theFaecal calprotectin test

Faecal calprotectin results provide an objective measure of intestinal inflammation that can help differentiate between inflammatory bowel diseases like ulcerative colitis or Crohn’s disease, and non-inflammatory conditions like irritable bowel syndrome.

The test is useful for evaluating the degree of active intestinal inflammation, monitoring treatment response and disease activity over time. High calprotectin suggests inflammation that may warrant endoscopic evaluation.

Understanding the Faecal Occult Blood Test

A faecal occult blood test (FOBT) is a simple, non-invasive screening test used to check for hidden blood in the stool. Small amounts of blood may indicate the presence of polyps, colitis, or even colorectal cancer, even before symptoms arise.

To perform the test, a small stool sample is collected at home using special cards or cloths. These are then returned to the surgery or laboratory, where the samples are checked for traces of blood not visible to the naked eye.

FOBTs use chemical reactions to detect haem, a component of the haemoglobin in red blood cells. There are a few different types including guaiac and immunochemical tests, with varying sensitivity and specificity.

Results are reported as positive or negative for blood. While not diagnostic, a positive FOBT warrants follow up with a colonoscopy or other procedures to investigate the source of bleeding.

Faecal occult blood tests are considered an important preventative screening tool. When performed regularly as recommended, FOBTs can help detect colorectal cancer early when treatment is most effective. Speak to your GP about whether this simple test may be right for you.

TIF: A New Non-Surgical Option for GERD

For those suffering from chronic acid reflux and GERD, a new minimally invasive procedure called transoral incisionless fundoplication (TIF) offers an innovative treatment without the need for major surgery.

The TIF technique is performed entirely through the mouth with an endoscope, without incisions. During the outpatient procedure, the surgeon creates a valve between the stomach and esophagus by gathering and stitching together folds of tissue. This recreates the body’s natural antireflux barrier to prevent acid from washing back up into the esophagus.

TIF is performed under general anesthesia and typically takes less than an hour. Most patients go home the same day and can resume a normal diet within a few days. Studies show TIF can significantly reduce dependence on acid reflux medications for many patients.

Compared to more invasive laparoscopic anti-reflux surgery, TIF has a quicker recovery, no external incisions, and preserves the patient’s natural anatomy. For appropriately selected patients, TIF is a safe and effective new endoscopic treatment to restore the gastroesophageal valve and control GERD symptoms.

What is gastroparesis ?

Gastroenterology

What is Gastroparesis

Gastroparesis, delayed gastric emptying, and issues with stomach accommodation are distinct yet interrelated concerns that merit exploration. Let’s unravel the complexities surrounding these conditions.

Gastroparesis:

Gastroparesis is a gastrointestinal disorder characterized by delayed emptying of the stomach contents into the small intestine. This delay results from impaired or weakened muscular contractions of the stomach, hindering the proper movement of food. Common symptoms include nausea, vomiting, abdominal pain, and a feeling of fullness, even after consuming small amounts of food.

Delayed Gastric Emptying:

Delayed gastric emptying is a broader term encompassing various conditions, including but not limited to gastroparesis. It refers to the sluggish movement of food from the stomach into the small intestine. This delay disrupts the normal digestive process and can lead to a range of symptoms, from bloating and indigestion to more severe complications.

Issues with Stomach Accommodation:

Stomach accommodation refers to the ability of the stomach to expand and contract to accommodate the ingested food. Issues with stomach accommodation may arise due to factors such as damage to the nerves controlling stomach muscles or abnormalities in the coordination of muscle contractions. This can result in difficulties with food intake and contribute to symptoms like early satiety and discomfort.

Causes and Risk Factors:

  1. Neuromuscular Dysfunction: Gastroparesis and delayed gastric emptying often stem from dysfunction in the nerves controlling stomach muscle contractions, leading to impaired motility.

  2. Diabetes: Diabetes is a significant contributor to gastroparesis, as high blood sugar levels can damage the nerves responsible for regulating stomach movement.

  3. Post-Surgical Complications: Surgical interventions in the abdominal area can disrupt the normal functioning of the stomach, potentially causing delayed gastric emptying.

  4. Connective Tissue Disorders: Conditions affecting connective tissues, such as scleroderma, can impact stomach accommodation and contribute to digestive issues.

Management and Treatment:

  1. Dietary Modifications: Adjusting dietary habits, such as consuming smaller, more frequent meals and avoiding certain foods that may be harder to digest, can help manage symptoms.

  2. Medications: Prokinetic medications may be prescribed to enhance stomach contractions and promote more efficient gastric emptying.

  3. Nutritional Support: In severe cases, nutritional support through enteral feeding or parenteral nutrition may be necessary to ensure adequate nutrient intake.

  4. Underlying Condition Management: Addressing the underlying causes, such as diabetes or connective tissue disorders, is crucial for effective long-term management.

What can not be seen during an abdominal ultrasound?

Gastroenterology

What cannot be seen during an abdominal ultrasound?

While abdominal ultrasound serves as a powerful diagnostic tool, there are certain aspects and conditions that elude its imaging capabilities. Understanding the limitations of this modality is essential for a comprehensive assessment of abdominal health. Let’s explore what may not be visible during an abdominal ultrasound.

Aspects Not Visualized by Abdominal Ultrasound:

  1. Detailed Assessment of Intestinal Structures: Abdominal ultrasound is limited in providing detailed images of the small and large intestines. Evaluation of specific intestinal layers and identification of subtle abnormalities may require alternative imaging methods such as CT scans or MRI.

  2. Evaluation of Gas or Air-filled Structures: Abdominal ultrasound faces challenges in visualizing structures that contain a significant amount of gas or air. This limitation can affect the assessment of certain portions of the digestive tract, like the stomach and portions of the colon.

  3. Evaluation of Solid Organs Behind Gas-Containing Structures: Gas in the digestive tract may hinder the clear visualisation of solid organs located behind these structures, affecting the ability to assess certain areas of the liver, pancreas, or spleen.

  4. Evaluation of the Retroperitoneum: The retroperitoneum, an area behind the abdominal cavity that houses structures such as the kidneys and aorta, may be partially obscured by overlying structures, limiting the ultrasound’s ability to provide a comprehensive view.

  5. Bone Structures: Abdominal ultrasound is not effective in visualizing bone structures. Conditions affecting the bones within the abdominal region, such as fractures or abnormalities, are better assessed through other imaging techniques like X-rays or CT scans.

  6. Limited Assessment of Blood Vessels: While abdominal ultrasound can assess major blood vessels, it may not provide a complete evaluation of smaller blood vessels or vessels located deep within the abdominal cavity.

Left Shoulder Blade Pain and the Digestive System

Gastroenterology

Left Shoulder Blade Pain and the Digestive System

Experiencing pain in the left shoulder blade can be a discomforting sensation, and while musculoskeletal issues are often deemed the primary causes, an intriguing connection exists between this pain and the digestive system. Understanding this correlation is crucial for comprehensive healthcare and effective management.

The Digestive System and Left Shoulder Blade Pain:

  1. Referral Pain from the Diaphragm: The diaphragm, a vital muscle separating the chest and abdomen, can refer pain to the left shoulder blade. Diaphragmatic irritation, often associated with gastrointestinal issues, can manifest as discomfort in this specific region.

  2. Gallbladder and Liver Issues: Problems with the gallbladder or liver, such as gallstones or inflammation, may cause referred pain to the left shoulder blade. The shared nerve pathways between the abdominal organs and the shoulder can contribute to the perception of pain in this unexpected area.

  3. Peptic Ulcers and Gastritis: Conditions like peptic ulcers or gastritis, characterised by inflammation of the stomach lining, can cause referred pain to the left shoulder blade. The intricate network of nerves connecting the digestive organs and surrounding areas can contribute to this phenomenon.

  4. Splenic Involvement: In some cases, conditions affecting the spleen, such as an enlarged spleen or splenic infarction, may lead to left shoulder blade pain. These conditions often have associated implications for the digestive system.

Addressing Left Shoulder Blade Pain Linked to Digestive Issues:

  1. Gastrointestinal Evaluation: If left shoulder blade pain persists, a comprehensive gastrointestinal evaluation is recommended. This may include endoscopic procedures, imaging studies, and laboratory tests to identify any underlying digestive system issues.

  2. Lifestyle Modifications: Dietary changes, such as avoiding trigger foods and adopting a balanced diet, can play a role in managing digestive issues that contribute to left shoulder blade pain.

  3. Medical Intervention: Treatment of specific digestive conditions, such as gallbladder disorders or gastritis, may involve medication, lifestyle adjustments, or, in some cases, surgical intervention.

Should you fast before an abdominal ultrasound?

Gastroenterology

Should you fast before an abdominal ultrasound?

An abdominal ultrasound is a non-invasive imaging procedure that uses sound waves to get detailed images of organs and structures in the abdomen. It is commonly ordered to assess a wide range of gastrointestinal issues.

Unlike some procedures, abdominal ultrasounds generally do not require any extensive preparation like fasting. This makes it a convenient diagnostic test for patients. The main exception is if your ultrasound is scheduled in conjunction with another procedure that involves sedation or you have existing gastrointestinal issues. Fasting helps prevent vomiting and aspirating stomach contents once sedated.

Additionally, having food or fluid in your stomach can impact image quality, as gas and solids can obstruct organ visualization. If the ultrasound targets the gallbladder, pancreas or liver specifically, your doctor may recommend fasting for 4 to 8 hours beforehand. This ensures clearer pictures and accuracy.

Aside from these specialized situations though, there is no universal fasting rule prior to a standard abdominal ultrasound. You can typically eat and drink as normal. Just be prepared to have a moderately full bladder, as you may be asked to hold urine which enables better imaging.

In summary, fasting is often unnecessary preparation for an abdominal ultrasound, allowing normal intake up until the test. But confirm if any restrictions apply based on procedural specifics or clinical concerns to support optimal results.
