Background:

Flexible sigmoidoscopy is a widely used screening tool for colorectal cancer.
Current guidelines recommend periodic screening for average-risk individuals starting at age 50.
The procedure necessitates comprehensive training in endoscopy, anatomy, and pathology.

Purpose of the Study:

To outline the standard procedure for flexible sigmoidoscopy.
To detail the recommended screening intervals and patient risk stratification.
To describe the recognition and management of common findings during the procedure.

Main Methods:

Insertion of a sigmoidoscope through the anus and rectum.
Advancement to the sigmoid colon (average 48-55 cm).

Slow withdrawal for mucosal inspection, with biopsy of polyps <5 mm and follow-up colonoscopy for larger polyps.

Main Results:

Physicians typically achieve unsupervised proficiency after 10-25 supervised sessions.
Commonly encountered conditions include diverticulosis, hemorrhoids, colitis, and pseudomembranes.
Preprocedural benzodiazepines may enhance patient comfort.

Conclusions:

Flexible sigmoidoscopy is an established endoscopic screening method for colorectal cancer.
Training and procedural technique are crucial for effective screening and polyp management.
The procedure allows for the identification of various colonic pathologies beyond cancer screening.
