GERD and LPR bariatric procedures


Gastroesophageal Reflux Disease (GERD) is a chronic digestive disease that occurs when stomach acid or, occasionally, bile flows back (refluxes) into your food pipe (esophagus). The backwash of acid irritates the lining of your esophagus and causes GERD signs and symptoms that are generally referred to as heartburn.

Obesity and Diabetes

Today, 8% of all adults suffer from Adult Onset Diabetes or Type II Diabetes. It is projected that by the year 2030, more than 25% of all adults will have diabetes. There is a direct relationship between the development of diabetes and obesity as 90% of patients with diabetes have at least Class I obesity (>50 lbs overweight). To date, the only truly successful strategy to address this problem for individuals is Weight Loss Surgery.

Barrett's Esophagus

Barrett’s Esophagus is a condition affecting the lining of the esophagus, the swallowing tube that carries foods and liquids from the mouth to the stomach. Barrett’s esophagus is caused by injury to the esophagus from the chronic backwash of stomach contents (like acid and enzymes) that occurs with acid reflux. There are no symptoms specific to Barrett’s esophagus, other than the typical symptoms of acid reflux (or GERD). Barrett’s esophagus has long been established as a pre-cancerous condition of the esophagus. Traditionally, its management has been limited to monitoring the condition with endoscopy with the hope that the disease would not progress to cancer.
hiatal hernia bariatric procedures

Hiatal Hernia

Any time an internal body part pushes into an area where it doesn’t belong, it’s called a hernia. The hiatus is an opening in the diaphragm – the muscular wall separating the chest cavity from the abdomen. Normally, the esophagus goes through the hiatus and attaches to the stomach. In a Hiatal Hernia, the stomach bulges up into the chest through that opening.
achalasia bariatric procedures


Achalasia occurs when the food tube (esophagus) loses the ability to squeeze food down, and the muscular valve between the esophagus and stomach doesn’t fully relax. The reason for these problems is damage to the nerves in the esophagus. There is no cure, but achalasia symptoms can usually be managed with minimally invasive (endoscopic) therapy or surgery.
gastroparesis bariatric procedures


Gastroparesis also called delayed gastric emptying, is a disorder that slows or stops the movement of food from the stomach to the small intestine. Normally, the muscles of the stomach, which are controlled by the vagus nerve, contract to break up food and move it through the gastrointestinal (GI) tract. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The movement of muscles in the GI tract, along with the release of hormones and enzymes, allows for the digestion of food. Gastroparesis can occur when the vagus nerve is damaged by illness or injury and the stomach muscles stop working normally. Food then moves slowly from the stomach to the small intestine or stops moving altogether.
esophageal cancer bariatric procedures

Esophageal Cancer

I was fortunate to train with the first group of surgeons to perform Minimally Invasive Esophagectomy (MIE) in Canada. Since the beginning of my practice, the management of esophageal cancer has been a focus of my surgical practice, specifically incorporating advanced endoscopic procedures to treating pre-cancerous Barrett’s disease and early-stage cancer and performing advanced laparoscopic/thoracoscopic procedures for locally advanced cancer. Thus, my practice affords my patients comprehensive therapy for all aspects of the Esophageal Cancer process.
stomach cancer bariatric procedures

Stomach Cancer

The stomach is an organ between the esophagus and small intestine. It is where digestion of protein begins. The stomach has three tasks. It stores swallowed food. It mixes the food with stomach acids. Then it sends the mixture on to the small intestine. Stomach Cancer can begin in cells in the inner layer of the stomach (Adenocarcinoma), or from the middle layer of the stomach wall (GIST tumor), or from the lymph supply of the stomach (Lymphoma). Over time, the cancer may invade more deeply into the stomach wall or spread to other organs. People with certain risk factors are more likely to develop stomach cancer. A risk factor is something that may increase the chance of getting a disease.
