Check with GI doc: every clinic may have slightly different instructions. We use two enemas, one the night before and one the morning of the procedure a few hours before. Hope this helps.

Flex sig: Usually you administer the fleets enema just prior to going to the hospital for the sigmoidoscopy so that the rectum is empty for the procedure. You could call the physician,who is to perform the sigmoidoscopy to get precise preprocedure instructions.

What are possible complications of a flexible sigmoidoscopy?

Depends: If the test is done with sedation (typically not necessary) then there are risks of sedation. Otherwise typical risks of this procedure can include pain or cramps, bleeding (especially if there will be biopsies), infection, missing a lesion or a perforation (hole in the intestine). That being said, these risks are very rare.

Colonoscopy: One has to know more about what is being evaluated. I use flexible sigmoidoscopy to evaluate known issues in the distal colon and rectum, frequently after a full colonoscopy has been done. I would ask your physician her opinion.

Not much: You will be under the influence of either an amnestic (blocks memory) and/or light sedative. You won't remember a thing and likely get a terrific nap in the process. Now, preparing for the experience by evacuating your bowels the day before can be challenging.

Evaluating the colon: In this procedure a flexible endoscope is passed via the anus, through the rectum up to the splenic flexure. The allows the evaluation of the distal 1/3 of the colon. Cramping during the procedure is common. Sedation can be used in the appropriate setting but is not necessary. A bowel preparation is generaly done prior. Enemas are generally sufficient.

What if the flexible sigmoidoscopy shows something abnormal?

Depends on findings: Flexible sigmoidoscopy looks at lower 1/3 of colon. Better look is with colonoscopy, which looks at entirety of colon. In general, if abnormality seen on flex sig, colonoscopy is recommended.
