Digestive Issue Diagnosis and Treatment

Gastrointestinal Screenings:

Our gastroenterologist uses advanced diagnostic tools and procedures to assess the health of your digestive system. From endoscopies to imaging studies, we provide thorough screenings to identify and address issues promptly.

Gastrointestinal Endoscopy

Upper Endoscopy (EGD):

An upper endoscopy, also known as an esophagogastroduodenoscopy (EGD), is a procedure commonly performed by gastroenterologists to examine the upper part of the gastrointestinal (GI) tract. This includes the esophagus, stomach, and the first part of the small intestine, known as the duodenum.

1. Purpose: Upper endoscopy is used to diagnose and, in some cases, treat conditions affecting the upper digestive system. Common reasons for performing an EGD include investigating symptoms such as persistent upper abdominal pain, nausea, vomiting, difficulty swallowing, or gastrointestinal bleeding. It is also used to diagnose conditions like gastroesophageal reflux disease (GERD), ulcers, and celiac disease, among others.
2. Procedure: During an upper endoscopy, the patient is usually given a sedative to help them relax. The gastroenterologist then inserts a thin, flexible tube called an endoscope through the mouth and into the esophagus, stomach, and duodenum. The endoscope is equipped with a light and camera, allowing the doctor to view the inside of the upper GI tract on a monitor.
3. Diagnostic and Therapeutic Capabilities: In addition to diagnosing conditions, the endoscope can be used to perform various therapeutic procedures. These might include taking biopsies (small tissue samples for examination), removing polyps, treating bleeding, and stretching or dilating narrowed areas.
4. Safety and Recovery: Upper endoscopy is generally safe, with risks of complications being relatively low. Common side effects might include sore throat, bloating, or nausea, but these typically resolve quickly. Patients usually recover from the sedative within a few hours and can return to most normal activities the same day.
5. Follow-Up Care: After an upper endoscopy, the gastroenterologist will discuss the preliminary findings with the patient. If biopsies were taken or polyps removed, additional follow-up might be needed to discuss lab results and any further treatment plans.

Colonoscopy:

A colonoscopy is an essential diagnostic and therapeutic procedure used to examine the inner lining of the large intestine (colon and rectum). Colonoscopy serves as a vital instrument for the prevention and early diagnosis of colorectal conditions, notably colorectal cancer. This critical procedure enables our skilled professional, Prof Dr Giovanni Leonetti, to thoroughly examine the inner surface of the colon. During the process, he can identify and effectively address issues such as polyps or inflammation, ensuring proactive management of colorectal health.

1. Expertise in Diagnosis: Dr. Leonetti would use colonoscopy to diagnose a variety of conditions affecting the colon and rectum, such as colorectal cancer, polyps, inflammation, ulcers, and areas of bleeding. His specialized training allows him to interpret the findings accurately and make informed decisions about any abnormalities found.
2. Polyp Detection and Removal: One of the critical aspects of a colonoscopy is the identification and removal of polyps, which are growths on the lining of the colon that could potentially become cancerous. Dr. Leonetti’s skill in performing colonoscopies enables him to detect and safely remove polyps during the procedure, which is a key step in preventing colorectal cancer.
