Laparoscopic Sleeve Gastrectomy

A laparoscopic sleeve gastrectomy is a less invasive surgery that reduces stomach volume with the remaining section left in the shape of a sleeve.

Roux-en-Y Gastric Bypass Surgery

A laparoscopic Roux-en-Y gastric bypass consists of creating a small pouch from the stomach (constraining food intake), which is connected directly to the small intestine.

Mini Gastric Bypass

A mini gastric bypass (MGB) provides the dual action of gastric reduction and intestinal malabsorption. The mini version of the gastric bypass involves less intestinal rerouting and a shorter overall surgery time.

Endoscopic Sleeve Gastroplasty

Endoscopic Sleeve Gastroplasty reduces the size of the stomach so that the patient feels full faster while eating. The procedure is performed endoscopically, meaning a camera is inserted through the mouth and esophagus and into the stomach.

Single Anastomosis Duodenal Switch

A single anastomosis duodenal switch (SADS) reduces bowel movement frequency as well as produces fewer side effects and vitamin deficiencies.

Duodenal Switch

The end product of a duodenal switch is two intestinal limbs. It combines a sleeve gastrectomy with an intestinal bypass. It is most effective for Type 2 diabetes. However, nutrient absorption is limited within the lower intestines.

Revisions Surgeries

With all the years of experience Dr. Gagner has accumulated, it is no wonder he is one of the world’s renowned experts in highly complex bariatric surgery revision procedures. Dr. Gagner can accommodate most patient cases. Once he has a chance to learn the peculiarities of a case, he can advise on the best course of action.

Diagnostic Surgery

When imaging techniques fail, we turn to diagnostic surgery to target the source of pain.

Benign Breast Lump Removal Surgery

During a clinical breast exam, your doctor will check both breasts for lumps, masses (fibroadenoma), and other problems. Sometimes the lumps will be too small to feel, so imaging (mammography, breast ultrasound) will be required to detect them. Once these masses are revealed, sampled, and analyzed, surgery may be required to remove them.

Hemorrhoidectomy - Hemorrhoid Surgery

Hemorrhoids are swollen veins in and around the most exterior part of your rectum and anus. With enough pressure and build-up of blood, these veins can protrude from the walls and lining of the rectum and anus.

It is the impaired ability to control the release of gas or stool at a desired time. A typical sufferer will have lost control of their anal sphincter, the muscle that constricts or relaxes the opening of the anus.

Fistulotomy - Anal Fistula Surgery

What is an anal fistula? It is a small tunnel connecting an infected abscess inside the anus to the outside skin around the anus. The abscesses are usually formed from anal mucus glands lining the walls of the rectum. Sometimes the glands can get clogged and become infected, leading to an abscess. There is a strong likelihood these abscesses develop into anal fistulas.

Gastroscopy

A Gastroscopy is an orally administered endoscopy and is performed for diagnostic or exploratory purposes.

Colonoscopy

A colonoscopy is a sort of test that is used to see inside your large intestine and colon. This is done by inserting a tube containing a flexible camera (called a scope or colonoscope) up your rectum. The insides of your colon are then shown on a screen for the doctor to examine and analyze.

Constipation – Partial Colectomy or Intestinal Resection Surgery

Constipation occurs when bowel movements become less frequent or harder to pass. In some instances, passing stool may become extremely painful, making it difficult or scary to go to the bathroom. Psychological impediments to passing stool can develop, further exacerbating the problem.

Ventral (Incisional) Hernia Repair Surgery

An incisional hernia is best described as a hernia that develops around an incision site, usually along the intestines, but may also occur on organs and other tissues, after a previous surgery. There is a significant risk with abdominal surgeries that an incisional hernia develops post-surgery.

Inguinal Hernia Repair Surgery

An inguinal hernia is best described as a hernia that develops along your abdomen, usually with the intestines, but may also occur with organs and other tissues, due to weak muscles in the abdominal wall. In essence, your intestines and other tissues may ‘slip’ through your abdominal wall and create a bulge along your abdomen, trapping them between your muscles and skin.

Umbilical Hernia Repair Surgery

An umbilical hernia occurs when parts of your intestines or fatty tissue pushes through a weak spot in the abdominal wall - in this case, near the navel - and gets trapped between your skin and abdominal wall, creating a painful bulge. Some patients are predisposed to umbilical hernias, such as newborns and infants, but they can affect adults as well.

Gallbladder Surgery (Laparoscopic Cholecystectomy)

The gallbladder is responsible for storing bile, the fat-digesting liquid produced by the liver. Over time, gallstones can form from the crystallization of bile components. Most people never have symptoms caused by the stones, until the onset of excruciating pain caused by a gallstone attack (biliary colic).
