Pre-Op check-up required before a bariatric procedure
All bariatric procedures are major surgical operations and carry a relatively high risk of complications. In order to minimize the risk, optimize the general condition of patients and make sure that patients are fit to undergo a bariatric procedure, a series of tests and examinations need to be done:
- blood tests, including complete blood count, serum biochemistry, blood coagulation profile, full hormonal check-up, hepatitis B/C and HIV serology.
- Plain chest X-ray
- Barium meal
- Upper GI endoscopy
- Referral to Cardiologist, Pneumonologist, Anaesthesiologist, Endocrinologist and Psychiatrist
What is the importance of a pre-op liquid diet?
In order to minimize the amount of fat around the liver and spleen, a preoperative liquid diet must be followed at least 2-3 weeks before a bariatric procedure.
A large, fatty liver may prevent accurate visualization of the anatomical structures by the surgeon during the procedure, thus rendering the procedure dangerous and unsafe for the patient. Many clinical studies have shown that patients that follow a diet before a bariatric procedure have much less complications during and after surgery.
Pre-op liquid diet must be strictly followed otherwise surgery might be delayed or even cancelled by many surgeons. This diet is typically low-calorie, often between 800-1200 calories. In general, you are asked to substitute meals with low-carb, sugar-free, high-protein shakes. Diet before surgery also prepares you for post-op diet which limits fat, sugar and carbs.
