Looking forward to seeing you in my clinic
I’m Dr. Mohamad El Hajj, with more than a decade of experience in the gastroenterology field (the digestive system and its problems).
For most of my career, I worked at Masarykova Hospital in Ústí nad Labem where I gained rich experiences and skills in diagnostics and treatment of digestive system problems, which has also continued to flourish during my work in Dubai.
I regularly perform abdominal ultrasound, diagnostic and therapeutic gastroscopy and colonoscopy including other procedures such as screening program of colon cancer, polyps or endoscopic interventions for obesity.
Our clinic offers:
- Complex intervention for digestive system
- Preventive and screening program
- Long-term care for patients with chronic digestive problems
- Abdominal ultrasound
- Diagnostic & therapeutic gastroscopy and colonoscopy
- Endoscopic interventions of obesity (intragastric balloon insertion/extraction or endoscopic application of Botox into the stomach)
- Laboratory work: Taking blood, stool and urine samples for our patients.
Gastroscopy
Procedure summary:
- For higher comfort, sedation is available
- Procedure duration: 5-10 minutes
- Fasting at least 8 hours before procedure
Preparation for the procedure
Required documents
- Gastroscopy is a procedure of the upper digestive system- esophagus, stomach, and duodenum which uses an optical tube- endoscope (gastroscope).
- The procedure is done on an empty stomach (fasting for at least 8 hours. In case of thirst, drink only clear liquids.)
- After local anesthesia of the oral cavity, we introduce a flexible tube with a camera on the end into the esophagus then the stomach and duodenum while the patient is lying on their left side.
- This procedure can, in some cases, be done under sedation- a drug administered into the vein that suppresses the feeling of discomfort. In any case, if the procedure is done under sedation, the patient is not allowed to drive or do any work requiring focus and attention. In these cases, it’s recommended to have a companion.
- During the procedure, we can take samples/biopsies or remove polyps/polypectomy for further study (histopathology)
- An alternative option is an X-ray with contrast; however, a gastroscopy doesn’t cause the patient a radiation burden and it’s far clearer, providing a better overview.
- The procedure isn’t painful, it’s only uncomfortable. The need to gag can best be overcome by taking slow, deep breaths.
- The procedure doesn’t take long, on average it takes 5-10 minutes, in some cases, especially in therapeutic procedures it may take longer.
- During the procedure, you’ll hold a mouth piece with your teeth, lips, or gums. After the procedure, there is the option of resting in the recovery room.
- This procedure, similar to other endoscopic procedures, is very safe. It carries a very low chance of complications, however, no doctor can ensure absolutely zero risks in any procedure.
Colonoscopy
Procedure summary:
- Procedure duration: 30-50 minutes
- Option of taking samples/biopsies
- Option to remove polyps/polypectomy
Preparation for procedure
Picoprep/similar drug + Dulcolax
Required documents
- Colonoscopy is an invasive procedure, which serves mainly to show the colon. It’s done by a flexible probe with a camera on the end- endoscope. The doctor gradually inserts the endoscope into the rectum into the place where the small intestine connects to the large intestine.
- The procedure usually lasts 30-50 minutes, in some cases, especially in therapeutic procedures, it may take longer.
- Preparation for procedure: see ‘Preparation for colonoscopy’
- Complications: No doctor can ensure absolutely zero chance of risk in any type of procedure. This procedure, just like any other endoscopic procedure, is very safe.
- General complications: reaction to given drugs (respiratory or cardiovascular side effects).
- Endoscopic complications: the worst scenario is perforation of the intestine, bleeding, or possibly of bacteremia and sepsis (flooding of bacteria into the vascular system). These complications may require further hospitalization and treatment, possibly even a surgical intervention. They can appear as sudden bleeding from the digestive tract with abdominal pain.
- Alternative procedures: An alternative is an X-ray procedure (irrigography, CT colonography) with contrast solution.
- After the procedure: After the procedure there is an option of resting in the recovery room. Don’t eat and/or drink for 2 hours. If any sedation was given, you can’t drive any motor vehicles or operate any heavy machinery for the next 24 hours due to the sedation lowering your concentration levels.
Preparation for colonoscopy
The day before the procedure only consume liquids.
In the morning, you can have a light breakfast which may include yogurt, yogurt milk, broth, and soup (without meat, noodles, and/or vegetables). During the day, don’t drink any juices with pulp, milk, and black coffee. If you are on any birth control pills the effects can be reduced due to the preparation for the procedures.
Clensia/similar drug + Dulcolax
Preparation before the procedure:
- 5 days before the procedure, you must stop consuming any medicine containing iron.
- 2 days before the procedure, you have to go on a low-fiber diet and avoid foods with small seeds (e.g. grapes, watermelon, wholemeal bread, poppy, etc.).
- Ideal foods are yogurts, meat, mashed potatoes, pasta, pudding, sponge cakes, white bread, crackers, rice, and broth. Follow a drinking regimen and drink at least 2 liters of liquids daily.
- Diabetics and patients with anticoagulation therapy should consult with their referral doctor to adjust their treatment. If you are a diabetic don’t forget to check your blood sugar (glycemia) more often.
- The day before the procedure, drink the Clensia or alternative drug+ Dulcolax according to the instructions. It is ideal to drink a lot of liquids along with the laxative.
- At 13:00 o’clock, take 2 Dulcolax tablets, and after 10 minutes empty the contents of four (4 sachets 2A and 2B) Clensia sachet into 1 liter of water, and mix for 2-3 minutes until fully dissolved and start slowly drinking the laxative over the course of 3-4 hours.
- At 18:00 o’clock, once again take 2 Dulcolax tablets and a second 4 sachets of Clensia, mix it into 1 liter of water, and drink it over the course of 2-3 hours.
- After drinking the laxative, you can only drink strictly clear liquids up to 6 hours before the procedure.
Abdominal ultrasound (sonography)
Procedure summary
- Procedure duration: 10-15 minutes
- Non-invasive and painless
- No radiation
- An abdominal ultrasound is non-invasive and painless procedure of the abdomen
- In gastroenterology it is used to check the abdominal organs (liver, gallbladder, bile ducts, pancreas, kidneys, intestine, urinary bladder, and major abdominal vessels)
- The patient should fast for at least 6 hours before the procedure
- An abdominal ultrasound is heavily affected by any gas in the colon, and that’s why it is recommended to avoid any flatulating foods
- It is necessary to remove your top, the doctor will apply a transparent gel and check your abdominal organs by using the ultrasound probe.
- The procedure takes around 10-15 minutes
- After the procedure, the patient will receive paper tissues to wipe off their abdomen
Endoscopic bariatry in gastroenterology
Endoscopic bariatric procedures in gastroenterology can be divided into several groups:
- Gastric volume reduction procedure
- Intragastric balloon (IGB) is a method that reduces the volume of the stomach and induces the feeling of being satiated and at the same time slows down gastric evacuation (movement of food from the stomach).
- Nowadays, there are a number of IGBs, which are usually filled with normal saline to a volume of about 400–700 ml.
- The insertion period is 6-12 months. The IGB is then extracted endoscopically.
- Average weight loss is 25 ± 5 kg
- One of the limitations of IGB is the risk of weight regain after the balloon is extracted.
- Studies have shown a decrease in the lipid profile, glycated hemoglobin or improvement in arterial hypertension compensation after IGB insertion.
- Studies have proven the safety of the method, and usually no serious complications occur.
- Possible complications after IGB insertion may include: continuous nausea and vomiting, abdominal pain, gastric ulcer, perforation.
- Delayed gastric emptying and early satiety induction / Gastroparesis
- Endoscopic application of botulinum toxin A through an injector into the antrum or fundus of the stomach.
- The mechanism of the action is to delay gastric emptying and early satiety induction.
- The effect of therapy is limited to a period of approximately 3–6 months.
- Average weight loss is 10 ± 5 kg
- Side effects: Nausea, abdominal pain, headaches, bloating, constipation or diarrhea.
