A colonoscopy is a common and routine procedure performed for the diagnosis and treatment of disorders of the large intestine (colon) and rectum.

Dr. Rosner performs private colonoscopy examinations at The Assuta Medical Centers and at additional recognized Medical Centers in Israel.

A colonoscopy is recommended for:

  • Colon cancer screening in women and men over the age of 45 years

  • Changes in bowel habits including constipation and diarrhea

  • Rectal bleeding

  • Evaluation of weight loss

  • Evaluation of iron deficiency anemia

  • Abdominal pain

  • Suspected Inflammatory Bowel Disease (Crohn’s Disease and Ulcerative Colitis)

  • Surveillance of individuals with an increased risk for colon cancer, including individuals with a personal or family history of colon polyps or cancer, or a known mutation in a colon cancer susceptibility gene

More about the Colonoscopy Procedure 

Your doctor will give you specific instructions to prepare for the procedure.

In the endoscopy room, you will be asked to lie on your left side and the doctor will give you an intravenous sedative to make you feel more comfortable and relaxed during the procedure.

After you have received the sedative, a long, thin, flexible tube (colonoscope/endoscope) is gently inserted to the rectum and is guided through the large intestine.

A small amount of air is pumped into the colon to inflate it.

The tip of the endoscope contains a tiny video camera that allows the doctor to see images of the inside of the lower gastrointestinal tract on a monitor in the endoscopy room. 


A colonoscopy is a screening, diagnostic and treatment tool. If the doctor finds abnormal tissues or polyps during the colonoscopy, minor surgical procedures such as a biopsy (taking a small tissue sample) and polyp removal can be performed.

The procedure normally takes 20 to 30 minutes.

After the procedure, you will be transferred to the recovery room where you will be supervised for approximately one hour until the effects of the sedation wear off. 

You will generally be discharged home about 1-2 hours after the examination.

The doctor will explain the results of your colonoscopy prior to discharge.

If a biopsy is taken, it will be sent to the laboratory for further testing.

Results are generally available within about a month and will be sent to you by the doctor.



Colonoscopy and Colon Cancer

Colon cancer is the second most common cancer in western countries and in Israel.

About 3,200 new cases of colon cancer are diagnosed annually; one third of the cases are fatal.

Colon cancer is treatable and often curable if it is caught in the early stages before it has spread.

Screening colonoscopy is the best tool to prevent colon cancer and detect disease in its earliest stages.
