Abstract

Insights

Surgical outcomes are increasingly linked to the gut microbiome. Understanding the complex interplay between host and microbial genes is crucial for advancing surgical practice and preventing rising infection-related complications.

Area of Science:

  • Surgical Science
  • Microbiome Research
  • Infectious Disease

Background:

  • Surgeons have long suspected the influence of intestinal microbes on surgical disease recovery.
  • Diseases like appendicitis, peritonitis, cholelithiasis, diverticulosis, peptic ulcer disease, and cancer are now understood to be significantly impacted by the microbiota.

Purpose of the Study:

  • To review evolving concepts in microbiome sciences relevant to surgical diseases.
  • To focus on disease etiology and treatment strategies influenced by the microbiome.

Main Methods:

  • This study is a comprehensive review of current literature on the microbiome in surgical contexts.
  • It examines the impact of microbial factors on the pathogenesis and management of various surgical conditions.

Main Results:

  • Peptic ulcer disease and some gastric cancers are now recognized as infectious diseases.
  • Viewing humans as superorganisms (host + microbial genes) is essential for advancing surgical practice.
  • Understanding the microbiome's role is vital for an aging population facing modern stressors.

Conclusions:

  • Rising infection-related complications post-elective surgery are a growing concern.
  • Resistant microbes, fueled by global travel and antibiotic use, contribute to these complications.
  • Further research into the microbiome's role in surgical disease is necessary for effective prevention strategies.

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Anatomy of the Intestines01:23

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...

Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
