Muscles of the Pelvic Floor and Perineum01:26

Muscles of the Pelvic Floor and Perineum

The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...
Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...
Inflammatory Bowel Disease V: Surgical Management01:21

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:
Muscles of the Abdomen01:21

Muscles of the Abdomen

The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and anterior...
Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...
Physiology of the Gastrointestinal System III: Elimination01:26

Physiology of the Gastrointestinal System III: Elimination

The gastrointestinal elimination process involves a complex interplay of neural and hormonal mechanisms that coordinate the final waste removal from the body. This intricate operation encompasses the absorption of water and electrolytes, vital for transforming the remaining indigestible food matter into feces. The large intestine is pivotal in water and electrolyte absorption, forming feces from unabsorbed minerals, undigested food, bacteria, bile pigments, and shed epithelial cells. Essential...

    Summary

    Researchers explored compensating for rectal obturator apparatus defects. An experimental model for encopresis and a transplant method were developed to address this condition.

    Area of Science:

    • Colorectal surgery
    • Transplantation medicine
    • Pediatric surgery

    Context:

    • Inborn pathologies of the rectal obturator apparatus can lead to encopresis.
    • Current treatment options for severe encopresis may be limited.
    • Developing effective compensatory strategies is crucial for improving patient outcomes.

    Purpose:

    • To investigate the potential for compensating inborn pathologies of the rectal obturator apparatus.
    • To develop an adequate experimental model for studying encopresis.
    • To establish a method for transplantological compensation of this pathological state.

    Summary:

    • An experimental model simulating encopresis was successfully created.
    • A novel method for transplantological compensation of the obturative apparatus pathology was developed.
