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.

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.

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.

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:
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.
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.
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.
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.
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.
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.

The abdominal ultrasound emerges as a powerful diagnostic tool, providing a non-invasive glimpse into the intricate structures residing within the abdominal cavity. Let’s delve into what this imaging modality reveals and why it is widely employed in healthcare diagnostics.
Insights Revealed by Abdominal Ultrasound:
Liver and Gallbladder: Abdominal ultrasound enables a detailed examination of the liver and gallbladder, aiding in the identification of liver abnormalities, gallstones, and conditions impacting bile flow.
Pancreas: The pancreas, a vital organ involved in digestion and blood sugar regulation, is scrutinized for signs of inflammation, cysts, or tumours through abdominal ultrasound.
Kidneys: Abdominal ultrasound provides a comprehensive view of the kidneys, facilitating the detection of kidney stones, cysts, or structural abnormalities that may impact renal function.
Spleen: The spleen, an organ integral to the immune system, is visualized for signs of enlargement, lesions, or other anomalies during abdominal ultrasound examinations.
Abdominal Aorta: The major blood vessel, the abdominal aorta, can be assessed for aneurysms or other vascular conditions, contributing to the evaluation of cardiovascular health.
Bladder and Prostate (in males): Abdominal ultrasound assists in assessing the bladder for issues like urinary retention and visualizing the prostate gland in males for signs of enlargement or abnormalities.
Reproductive Organs (in females): In females, abdominal ultrasound allows for the examination of reproductive organs, including the uterus and ovaries, aiding in the diagnosis of conditions such as ovarian cysts or uterine fibroids.
Benefits of Abdominal Ultrasound:
Non-Invasive Nature: Abdominal ultrasound is a non-invasive procedure, eliminating the need for surgical intervention while providing detailed images of internal structures.
Real-time Imaging: This imaging technique offers real-time visuals, allowing healthcare professionals to observe organ function and detect abnormalities promptly.
Safety: Abdominal ultrasound does not involve exposure to ionizing radiation, ensuring a safe diagnostic option, particularly for pregnant individuals.

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.

A colonoscopy is an important screening test that visualises the large intestine using a tiny camera. It helps detect and remove benign growths or early cancers, enabling better colorectal health outcomes.
General guidelines advise that those at average risk start regular colonoscopy screening at age 50 until at least 75. The frequency varies between every 10 years or more often depending on screening history and what is found. Earlier or more frequent surveillance is warranted if you have a family history of colorectal issues or relevant symptoms.
In any age group, a colonoscopy is strongly recommended if worrying digestive red flags arise. These include rectal bleeding, iron deficiency anaemia, persistent diarrhoea or constipation, abdominal pain, unexplained weight loss or positive faecal blood. Do not hesitate to consult your GP regarding a colonoscopy if you experience these. Acting quickly maximises the chances of early treatment if any abnormalities exist.
Finally, your doctor may suggest repeat short interval colonoscopies if precancerous polyps were found, or previous colon or rectal cancer exists. This tighter surveillance enables optimal monitoring and prevention.
In summary, from your 50s onwards or if concerning digestive symptoms appear, a timely colonoscopy is critical for ruling out problems and maintaining bowel health. Discussing risk factors with your doctor ensures appropriate screening recommendations.

A gastroscopy, also known as an upper endoscopy, allows visual examination of the oesophagus, stomach and duodenum. During this procedure, an endoscope (small camera) is passed through the mouth to provide gastrointestinal images. As this can cause some discomfort, you may wonder whether sedation is advisable.
For many patients, gastroscopy is easily tolerable without sedation. Sensations of pressure and fullness may occur when the scope passes through, but serious pain is uncommon. Being able to follow instructions also enables quicker procedures.
However, anxious patients or those worried about discomfort may benefit from sedation. Though uncommon, some also experience painful gastroscopies due to gastrointestinal strictures or anatomical sensitivities. Sedation can ease any unpleasant sensations in these cases. It allows patients to relax through quicker procedures as well.
The option exists for conscious sedation with a mild sedative and pain relief medication. This causes drowsiness but patients can still follow commands if needed. It avoids risks of deeper sedation while minimising discomfort. Discuss the pros and cons with your endoscopist to determine if conscious sedation suits your situation.
In summary, for most routine gastroscopies sedation is helpful but not always necessary. It can allow relaxation and ease pain when required. Consider your personal factors before deciding whether to opt for conscious sedation.
