Bariatric surgery is a type of procedure that can be used to achieve significant weight loss in individuals who are very obese (morbidly obese). A thumb-sized stomach pouch is created (using a stapling or banding technique) then the outlet of the pouch is connected directly to the intestine, essentially bypassing the lower stomach. After the surgery, the amount of calories your body can intake is reduced which leads to weight loss.

During colon resection surgery (bowel resection) the diseased part of the large intestine is removed and the two healthy ends are sewn back together (resectioned). This surgery is used to treat many conditions, such as bowel obstruction, diverticulitis, Crohn’s Disease and colon cancer. A bowel resection may be performed as a traditional "open" procedure or as a minimally invasive laparoscopic procedure. The surgery is performed in a hospital setting under general anesthesia and can involve a hospital stay of up to 7 days.

Gastrectomy is the surgical removal of all or part of the stomach and reconnection to the small intestine. This surgery used to treat stomach cancer, noncancerous polyps, gastric ulcers, or a hole in the stomach wall. The surgery is performed under general anesthesia and usually involves a seven to ten day hospital stay. If combined with other procedures, the stay can be lengthy.

Hemorrhoid surgery (also called hemorrhoidectomy) is the surgical removal of hemorrhoids. Hemorrhoids are swollen or enlarged veins located inside (internal) and outside (external) the anus. They are usually caused by straining when constipated or during pregnancy. The surgery can remove large internal hemorrhoids that do not respond to non-surgical treatment and large external hemorrhoids.

Hernia repair (or Herniorrhaphy) involves surgery to correct an abnormal protrusion of an organ through the wall of the area that normally holds the organ. This can happen when the outer layers of the abdominal wall weaken, bulge or rip. Most hernia repairs can be done on an outpatient basis using either the conventional open surgery or laparoscopic.

Laparoscopic gallbladder removal (also known as laparoscopic cholecystectomy) is the procedure where the gallbladder is removed using instruments inserted through small incisions in the abdomen. The procedure is performed in an operating room with the patient under general anesthesia.

A liver biopsy is a medical procedure to remove a small amount of tissue from the liver for examination. The biopsy helps diagnose a number of liver diseases or assess the stage (early, advanced) of liver disease. This is especially important in hepatitis C infection. The biopsy also helps detect: infections, cancer, unexplained enlarged liver, or abnormal liver enzymes detected by blood tests. The biopsy is performed in a hospital setting and under local anesthesia. The physician will use a needle to remove a small piece of the liver. The tissue is then sent to the laboratory for evaluation.

Lumpectomy is the surgical procedure where a cancerous lump or tumor in the breast is removed. The procedure is recommended only for those patients with less than a quarter of the breast involved.

A lung biopsy is a medical procedure where a small amount of lung tissue is removed and examined by a pathologist for any abnormalities. The procedure is used to diagnose certain lung conditions such as pulmonary fibrosis (scarring of the lungs with fibrotic tissue), sarcoidosis (clumps of cells formed in various organs), and cancer. There are four types of lung biopsies: bronchoscope biopsy (bronchoscope insert through mouth or nose), needle biopsy (needle inserted through chest), open biopsy (through surgical incision between ribs), and video-assisted thorascopic (thorascope through incision). The first two are outpatient procedures performed by a pulmonologist under local anesthesia. The second two are in-hospital surgical procedures performed by a thoracic or general surgeon.

Mastectomy is the surgical removal of the breast for treatment of cancer. A mastectomy may involve the complete removal of the breast with or without the nipples, lymph nodes, axillary lymph nodes, or major/minor chest muscles.

Splenectomy is the surgical removal of a diseased or damaged spleen. A splenectomy can also be performed as a treatment for some blood disorders and some cancers. A complete splenectomy removes the entire spleen, while a partial splenectomy removes only a part of the spleen. A splenectomy can be performed in conjunction with another partial organ removal, such as the pancreas. The spleen is in the uppermost area of the left side of the abdomen, just under the diaphragm. In healthy people, the spleen plays a role in immunity against bacterial infections and a reservoir for blood. A splenectomy can be performed either open or laparoscopic.
