Rigid sigmoidoscopy has no longer the value it had in the past, before the advent of videocolonoscopy (flexible sigmoidoscopy). However, it may be still useful in ano-rectal diseases such as bleeding per rectum or inflammatory rectal disease, particularly in the general practice and pediatrics.

During a sigmoidoscopy, a doctor closely inspects the lower parts of the colon, called the sigmoid colon and the descending colon, for signs of cancer or polyps. Polyps are small growths which can over time become cancer. The doctor uses a slender, flexible, hollow, lighted tube about the thickness of a finger. This "sigmoidoscope" is gently eased inside the colon and has a tiny video camera, which sends pictures to a TV screen.

There are two types of sigmoidoscopy, flexible sigmoidoscopy, which uses a flexible endoscope, and rigid sigmoidoscopy, which uses a rigid device. Flexible sigmoidoscopy is today generally the preferred procedure.

Flexible sigmoidoscopy enables the physician to look at the inside of the large intestine from the rectum through the last part of the colon, called the sigmoid or descending colon. Physicians may use the procedure to find the cause of diarrhea, abdominal pain, or constipation. They also use it to look for benign and malignant polyps, as well as early signs of cancer in the descending colon and rectum.

Flexible sigmoidoscopy and colonoscopy are endoscopic procedures that allow doctors to examine the lining of the large intestine. In both procedures, the physician inserts a flexible tube known generically as an endoscope through the anus. The doctor is able to move this tube through the gut to view the mucosal lining of the intestines. This also enables him to take tiny samples of the lining using a forceps passed through the endoscope.

In the following situations, a sigmoidoscopy may be more appropriate than a colonoscopy: 1) If the symptoms suggest that the problem might be found in the lower part of the colon, a sigmoidoscopy might render an answer faster and with less preparation than a colonoscopy.

We are often asked by those who first hear about us "Why is Rigid Design Solutions different? Why should I choose Rigid over somebody else?" We think that not only is this a fair question, it is an important one. There are thousands of web design companies on the Internet, many of them offering seemingly inseparable services.

Rigid couplings serve as compact, economical components for the timing, joining or aligning of shafts at lower speeds and torque, particularly where zero backlash is desired. They are not intended for use as a critical part of a drive line or as a substitute for flexible or universal joints or other power transmission devices. As they are applicable for aligned shafts only, they are the most basic but often most cost-effective coupling option.

A sigmoidoscopy is a shorter test that requires less preparation, but is less thorough. A colonoscopy requires greater preparation the day before and sedation for the procedure, but provides a more extensive examination of the colon. It has been shown that up to 50% of polyps and other findings can be missed with a sigmoidoscopy; hence there has been a trend towards performing a coIonoscopy rather than sigmoidoscopy.

Yes the standoffs may be easily cut to custom lengths. The standard sizes range from 3“ to 5 3⁄4” and additional rods are available to 48”.

Some persons develop Huntington disease as adults, but without the chorea. They may appear rigid and move very little, or not at all, a condition called "akinesia." These individuals are said to have akinetic-rigid HD or the Westphal variant of HD.

Yes. Though not as common, several grades of DYMAX products are hard and rigid with a shore hardness of D80 or higher.

All airships use an envelope (balloon-like bag of gas) to lift the airship. Some used a metal "skeleton" or frame inside the envelope to give shape to the ship; these were called rigid airships, and examples included the R100 and R101 in England, the Graf Zeppelin and Hindenburg in Germany and the Akron, Macon and Los Angeles in the USA.

A colonoscopy is considered the "gold standard" for colorectal screening because it enables doctors to visualize the entire colon to find and remove polyps. A sigmoidoscopy can only provide visual information on the lower third of the colon.

Tubing becomes hard when exposed for long periods to the lipids found in human skin. Treat the tubing with a vinyl protector once a month to help slow down the process.
