Health City Bariatric Surgery

The bariatric surgery team at Health City Cayman Islands is committed to helping patients overcome chronic obesity and the many serious health risks it poses.

Health City Cayman Islands follows the WHO Guidelines to determine who qualifies for surgery, including:

  • BMI ≥ 40, or more than 100 pounds overweight.
  • BMI ≥35 and at least one or more obesity-related co-morbidities such as type II diabetes (T2DM), hypertension, sleep apnea and other respiratory disorders, non-alcoholic fatty liver disease, osteoarthritis, lipid abnormalities, gastrointestinal disorders, or heart disease.
  • Inability to achieve a healthy weight loss sustained for a period of time with prior weight loss efforts.
  • Failure of all other physician-supervised weight loss treatment options.

Types of Bariatric Procedures

The most common bariatric surgery procedures are Roux-en-Y gastric bypass, mini-gastric bypass and sleeve gastrectomy. At Health City Cayman Islands, the surgeons can perform these laparoscopically, which means making one or several very small incisions in the abdomen, rather than a major surgical incision. Utilizing minimally invasive surgical techniques leads to faster recovery and less risk of complications for patients.

Health City Cayman Islands also provides a non-surgical option known as the intra-gastric balloon procedure for patients with a BMI of 30 – 40. This procedure involves an inflatable medical device being temporarily placed into the patient’s stomach, for up to one year, to reduce weight. In general, intra-gastric balloons are placed endoscopically and the procedure has been performed under conscious sedation or general anesthesia with success. Balloon insertion and extraction are associated with relatively few operative complications. Long-term success requires lifelong compliance of dietary habits, nutritional guidelines, and exercise – working with a multidisciplinary bariatric team.

NEW procedure: OverStitch - gastric suture

This state-of-the-art procedure involves an incisionless, transoral, endoscopic approach and is performed with an endoscopic suturing device.

Gastric Suturing has multiple benefits:

  • It can be offered as a day case procedure with very minimal downtime
  • It is offered to patients with a lower BMI of between 30-40. Candidates with BMIs of over 40 are more suitable for a gastric sleeve or bypass
  • Patients can follow a relatively normal dietary regime within 1 month
  • Patients are still eligible even if they have multiple co-morbidities
  • The age limit is 65 years
