Gastroscopy : A Deep Diagnostic Tool, Simple and Safe

     Gastroscopy is an advanced medical technique that enables physicians to detect abnormalities in the digestive system. It is classified into two types: upper gastrointestinal endoscopy and lower gastrointestinal endoscopy.

The Importance of Gastroscopy

     Colorectal cancer is increasingly prevalent, ranking third among men and fifth among women. Current medical guidelines recommend a colonoscopy starting at age 50, even in the absence of symptoms, as statistics show a higher incidence of colorectal cancer in this age group. However, individuals with a family history of colorectal cancer or symptoms such as abnormal bowel movements, alternating constipation and diarrhea, rectal bleeding, or unexplained weight loss should undergo screening earlier rather than wait until age 50.

Types of Gastroscopy

1. Upper Gastrointestinal Endoscopy

     This procedure allows physicians to examine and assess the esophagus, stomach, and duodenum. It is commonly used to diagnose conditions such as:

• Helicobacter pylori-related gastritis
• Gastroesophageal reflux disease (GERD)
• Esophageal disorders
• Peptic ulcers

2. Lower Gastrointestinal Endoscopy

     Lower GI endoscopy involves examining the colon, rectum, and terminal ileum. Colonoscopy, a type of lower GI endoscopy, is particularly important for detecting abnormalities at an early stage, even before symptoms appear. This is especially crucial in diagnosing colorectal cancer, which is more prevalent in individuals aged 50 and above.

Colonoscopy

A colonoscopy is a diagnostic procedure using a thin, flexible tube with a camera inserted through the rectum to inspect the colon and terminal ileum for abnormalities. Individuals who should consider undergoing a colonoscopy include:

• Ages 40–50
• Family history of colorectal cancer
• Chronic abdominal pain
• Bloody or mucus-streaked stools
• Black stools, palpable abdominal masses, or unexplained weight loss

Preparation for Gastrointestinal Endoscopy

Before the Procedure:

• One day before the procedure, consume light meals such as porridge or rice soup.
• Avoid vegetables, fruits, dietary supplements, iron supplements, and anti-diarrheal medications.
• Some patients may need to take laxatives the night before or colon-cleansing medication on the morning of the procedure.
• Fast for at least 6 hours before the procedure.

During the Procedure:

Patients receive sedation to ensure comfort while the endoscope is inserted.

After the Procedure:

• Patients rest at the hospital for 2–3 hours to recover from the sedative.
• Mild bloating may occur due to air introduced into the intestines during the procedure, but it resolves naturally within minutes.
• Most patients can eat and resume normal activities soon after the procedure.
