Proctosigmoidoscope or Rigid Sigmoidoscope
The Proctosigmoidoscope, also called as Proctoscope or rigid sigmoidoscope, is a thin but rigid tube fitted with a camera, light and lens. This is a five in one device. This tube is made of stainless steel. It’s a merger of a telescope, endo camera, light source, instrumentation channel and sheath. This device comes with a video camera and 6 LED lights. It is used by doctors to examine the rectum and the lower part of the large intestine (colon). It is gently inserted through the anus into the rectum. The name of this procedure is proctoscopy or rigid sigmoidoscopy. The rigid sigmoidoscope can be bent from the tip in four directions.
The Proctosigmoidoscope is also used to detect signs of hemorrhoids, cancer and polyps. This procedure helps in the diagnosis and prevention of various colon and rectal diseases.
Use of Proctosigmoidoscope, Rigid sigmoidoscope
Many diseases or conditions affect your rectum or colon. With the help of a proctosigmoidoscope, the doctor examines the rectum and the lowest part of the large intestine. The doctor can use the rigid sigmoidoscope , proctosigmoidoscope for the following reasons –
- To detect diseases in your rectum or colon
- To find the source of bleeding in the rectum
- To find the cause of diarrhea or constipation
- To stop the growth or development of existing polyps
- To check for colon cancer or to monitor previously treated rectal cancer

Complete specifications of Rigid Video Procto-Sigmoidoscope are as follows: It is made of a stainless-steel tube (figure:1B,6 and figure:2,5) with working length of 30 cm and outer diameter of 10 mm and 15 mm. The rigid instruments have a detachable obturator which is blunt which is put into sigmoidoscope before inserting into the anus to avoid injury to the patient. Since that is not possible in this instrument, this instrument is given a fixed and blunt round obturator as a tip. (Figure:1A 2,5 and figure:2,1) The video camera of is fixed at the upper end of this obturator. (Figure:1A,3 and figure:2,2). The video signal from the camera is carried by a bunch of wires (figure:2,4) through the metal tubes and connected to the analogue to digital circuit (figure:2,7) placed in the cylinder-shaped holder. (Figure:1B,7 and figure:2,6) The output of this circuit is given to the USB pin placed in the cylindrical holder. This holder is placed perpendicular to the stainless-steel tube. Behind the holder, there is a round cap (figure:1B,9 and figure: 2,9) This cap gives support to the main stainless-steel tube. The instrumentation channel passes through this cap through a small hole. A USB wire connects the device to variety of devices such as desktop, laptop, android mobile phones and android based tabs. The device comes with software which needs to be installed on the display devices to see and records the images and the video. The video camera has LEDs (figure:1A,4) which are powered by the power from USB pin. The LEDs illuminate the field during the procedure. The device has an instrumentation channel fixed in front at the lower end of the Delrin obturator. (Figure:1A,1 and B,10 and figure:2, 3,12) It has an inner diameter in the range of 0.1 mm to 15 mm that accommodates a variety of instruments. The back of the instrument channel is in a round hub. (Figure:1B,12 and figure:2,10). This round hub has a groove (figure:1B,13) Over this groove attaches a silicone washer (figure:1B, 13) so that the air or gas should not leak during the procedure. At the side of the Delrin hub, there is a side channel with a nozzle with a Luer lock (figure:1B,11 and figure:2,11) which is welded to the main instrumentation channel. Thus, gas channel and instrumentation channel are common. The gas channel allows for gas insufflation during the procedure. To this channel, a balloon of BP apparatus may be attached for air insufflation. Alternatively, gases such as O2 or Co2 can also be connected with a tubing.
Parts of the Proctosigmoidoscope
The Proctosigmoidoscope is about 30 cm long and has zero degree vision. It has a camera and a light on the tip. The main part of this instrument is cylindrical and is made of stainless steel. It is hollow so that the rectum can be cleaned properly. It also has a side port for gas or air insufflation. The Rigid Sigmoidoscope can be used more than once. Its USB wire can be connected to any laptop, desktop, android mobile devices and tabs. The instrument comes with a software that you will need to install.
The handle is ergonomically designed to make it easy to hold and use the proctosigmoidoscope. The tip is smooth and rounded so that it can be inserted comfortably into the rectum without causing any bruising. There is also a light at the end of the instrument that illuminates the walls of the rectum and colon so that the doctor can see clearly.
How the proctosigmoidoscope is used
Your doctor will ask you to undress from the waist down and lie on your left side with your knees bent on a table. The doctor will first perform a preliminary digital rectal examination with gloved fingers. This test checks for blockage or tenderness of the rectum. After this examination, he will use the lubricated rigid sigmoidoscope and gently insert it into your rectum. You may feel uncomfortable during this process and feel like cramping but this is quite normal. This test does not cause any kind of pain but if you feel like you are afraid of pain then you can ask the doctor for anesthesia. Proctosigmoidoscopy will only take about 5 to 15 minutes.
What happens after proctosigmoidoscopy
After proctosigmoidoscopy, most people get busy with their normal work. If your doctor has used air in your rectum, then you may feel bloating or gas. You are likely to have light bleeding 1 or 2 times during the toilet, often this is due to Biopsy.
Who can use the Proctosigmoidoscope
Only gastroenterologists and colorectal surgeons can use the Rigid Sigmoidoscope. Proctosigmoidoscope is used to examine the anus and rectum. The doctor can remove some small tissue samples during the Proctosigmoidoscopy.
Proctosigmoidoscope vs other scopes
Rigid Sigmoidoscope or Proctoscope: It only examines the rectum and anus
Anoscope: It is smaller than the proctoscope and is used only to examine the anus.
Flexible sigmoidoscope: It is a long flexible tube that goes into the rectum and colon.
Colonoscope: It is the longest flexible scope that examines the large intestine.
