About Sigmoidoscopy

Sigmoidoscopy is a minimally invasive endoscopic procedure used to examine the rectum and sigmoid colon (lower part of the large intestine).

Overview

  • Evaluates rectal bleeding and chronic diarrhea

  • Detects polyps and early colorectal abnormalities

  • Assesses inflammatory bowel disease (IBD)

  • Screens high-risk individuals for lower colon pathology

  • Allows biopsy collection during the procedure

Workflow

Step 1: Limited Bowel Preparation
Mild bowel cleansing (enema or prescribed preparation) before the procedure.

Step 2: Patient Positioning
Patient lies comfortably on the examination table.

Step 3: Scope Insertion
Flexible sigmoidoscope is gently inserted into the rectum.

Step 4: Visual Examination
High-definition camera evaluates the rectum and sigmoid colon.

Step 5: Biopsy (If Required)
Suspicious tissue samples are collected for laboratory analysis.

Step 6: Reporting
Findings are documented and explained to the patient.
