Anatomy of the Intestines

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...

Intestinal Obstruction I: Introduction

Intestinal Obstruction I: Introduction

Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Anastomoses

Anastomoses

In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.
Arterial Anastomosis: These occur between arteries. They are most common in...

Summary

This study validates porcine intestine as a surgical simulation for intestinal anastomosis. Hand-sewn anastomosis simulation effectively differentiates skill levels, offering a valuable training tool.

Area of Science:

Surgical Education
Gastrointestinal Surgery
Medical Simulation

Background:

Current surgical simulation modules for open surgery are limited in scope and lack thorough validation.
Existing simulations utilize synthetic materials with limited fidelity or expensive, inaccessible animal laboratories.

Purpose of the Study:

To develop and validate an intestinal anastomosis simulation using thawed porcine intestine.
To assess the face, content, and construct validities of this simulation for both hand-sewn and stapled techniques.

Main Methods:

Participants performed hand-sewn and stapled anastomoses on thawed porcine small bowel.
Anastomoses were evaluated for adequacy, luminal narrowing, and bursting pressure.
Face, content, and construct validities were assessed by comparing junior residents, senior residents, and faculty.

Main Results:

Both hand-sewn and stapled anastomoses demonstrated strong face and content validity, with positive participant feedback.
Significant differences in completion times for hand-sewn anastomoses were observed between junior and senior residents, and PGY-1 and faculty.
Stapled anastomoses showed no significant differences in completion time or bursting pressure across skill levels.

Conclusions:

Inanimate intestinal anastomoses using porcine tissue serve as valid simulations for intraoperative experience, particularly for hand-sewn techniques.
The hand-sewn anastomosis simulation demonstrates good construct validity by differentiating between varying skill levels.
While stapled anastomosis simulation lacks strong construct validity, the overall porcine model offers a promising training modality.
