Abdominal surgery broadly covers procedures that involve opening of the abdomen. Diseases affecting the abdominal cavity are dealt with generally under their own names, e.g., appendicitis. The three most common abdominal surgeries are:

  • Exploratory Laparotomy: This refers to the opening of the abdominal cavity for direct examination of its contents, for example, to locate a source of bleeding or trauma.
  • Laparoscopy: This refers to a minimally invasive approach to abdominal surgery where rigid tubes are inserted through small incisions into the abdominal cavity. The tubes allow introduction of a camera, surgical instruments and gases into the cavity for direct or indirect visualization and treatment of the abdomen. The abdomen is inflated with carbon dioxide gas to facilitate visualization and often a small video camera is used to show the procedure on a monitor in the operating room. The surgeon manipulates instruments within the abdominal cavity to perform procedures such as cholecystectomy (gallbladder removal), the most common laparoscopic procedure. The laparoscopic procedure speeds recovery time and reduces blood loss and infection as compared to the traditional “open” cholecystectomy.
  • Bowel: Bowel resection is surgery to remove a diseased or cancerous segment of the intestine. The intestine is a 20-foot long tube coiled inside the abdomen running from the stomach to the rectum. It’s the part of the digestive system in which nutrients are absorbed and waste material is formed into stool. To accomplish the resection, the surgeon will make an incision in your abdomen over the part of the bowel to be removed. After the removal, the surgeon may need to temporarily leave an opening to the intestine through the wall of the abdomen. The opening is known as a “stoma,’ and the operation to create it called an ostomy. There are two types of ostomy:
    • (a) Ileostomy-This operation creates an opening to the small intestine (ileum) through the surface of the abdomen. Intestinal contents draining from this location are no thicker than toothpaste.
    • (b) Colostomy-This operation establishes an artificial outlet for the large intestine (colon). Waste draining from this opening will be soft or more formed depending on the part of the colon removed. The entire procedure usually takes one to four hours.

Surgery may be the first line of attack against breast cancer. Decisions about surgery depend on many factors. You and your doctor will determine of type of surgery that is most appropriate for you based on the stage of the cancer, the nature of the cancer and what is most acceptable to you in terms of your long-term peace of mind..


The gallbladder, an organ of the gastrointestinal system involved in the storage and concentration of bile, is shaped like a deflated balloon or pear, and lies on the surface of the right lobe of the liver. One of the most common disorders of the gallbladder occurs when cholesterol mixes with bile and calcium to form gallstones. Gallstones usually have to be surgically removed. In some cases, the entire gallbladder must be removed.

 Surgery for children

doctor bear logoAt Markham Stouffville Hospital we care about ensuring a positive experience for our smallest surgical patients and their families. We have invested in providing support to both children and their families during surgical experiences by providing the expertise of a child life specialist as well as the Dr. Bear program which is a paediatric program to help children preparing for surgery to understand and know what to expect. This support decreases anxiety and helps children have a positive memory of their experience with us. 

In order to focus individual attention on children having surgery, we are unable to invite siblings to the Dr. Bear Program. However, both parents are welcome to accompany their child.

To register, please call your child's surgeon's office.

Location and Hours 
Top floor of Building B in unit 4Wf room B4611
