Image Highlights

  1. Patient Preparation

    The patient is positioned in the left lateral decubitus position. Bowel prep must be completed; clear visualization depends on this.

  2. Scope Introduction

    The colonoscope is inserted gently into the rectum under direct visualization. Lubrication and air insufflation assist in maintaining lumen orientation.

  3. Navigate the Sigmoid & Descending Colon

    Progress through the sigmoid requires careful torque and loop reduction. Maintain insufflation and patient comfort.

  4. Crossing the Transverse Colon

    Advance past the splenic flexure into the transverse colon. Monitor luminal orientation; apply abdominal pressure as needed.

  5. Cecal Intubation & Confirmation

    Reaching the cecum marks full colonoscopy. Confirm landmarks: appendiceal orifice and ileocecal valve.
