Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

The Integrated Cognitive Simulator (ICS) shows high usability for surgical training. It effectively enhances cognitive skills in first-year laparoscopic appendectomy trainees, but not motor skill confidence.

Area of Science:

Medical Education
Surgical Simulation
Human-Computer Interaction

Background:

The Integrated Cognitive Simulator (ICS) is a software tool for clinical procedure training.
It combines text, anatomy, video, and simulation elements.
This study evaluated the ICS laparoscopic appendectomy module.

Purpose of the Study:

To assess the usability of the ICS laparoscopic appendectomy module.
To determine the effectiveness of the ICS in training cognitive skills for laparoscopic appendectomy.
To evaluate its impact on surgical trainees' learning experience.

Main Methods:

A randomized controlled trial was conducted with junior surgical trainees.
Participants were divided into control and intervention groups (ICS access).

E-Patient Counseling Trial (E-PACO): Computer Based Education versus Nurse Counseling for Patients to Prepare for Colonoscopy

Published on: August 1, 2019

Assessments included demographic questionnaires, procedural knowledge tests, and usability questionnaires.

Main Results:

The ICS demonstrated high usability scores (median 5/7 or higher for interface, functionality, usefulness).
First-year trainees using ICS showed significantly higher procedural knowledge scores than controls (14.9 vs. 12.1, P=0.04).
Second-year trainees did not show significant improvement; ICS use did not affect perceived need for intra-operative guidance.

Conclusions:

Trainees found the ICS highly usable for surgical training.
The ICS is effective for improving cognitive skills in first-year laparoscopic appendectomy trainees.
Cognitive skills training alone does not enhance confidence in performing motor tasks.
