Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

1.9K
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,...

Large Intestine01:09

Large Intestine

7.0K
The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

Muscles of the Pelvic Floor and Perineum

6.2K
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...

Inflammatory Bowel Disease V: Surgical Management

878
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:

Aneurysm I: Introduction

626
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Oral Cavity01:11

Oral Cavity

4.0K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

    Summary

    Anal fissures are common, painful anal canal ulcers causing pain and bleeding. Treatment ranges from conservative measures like increased fiber and fluids to surgical options for chronic cases.

    Area of Science:

    • Proctology
    • Gastroenterology

    Background:

    • Anal fissure is a frequent and painful proctologic condition.
    • It presents as a linear ulcer in the anal canal, causing pain and bleeding.

    Purpose of the Study:

    • To outline the diagnosis and treatment strategies for anal fissures.
    • To differentiate between acute and chronic anal fissure management.

    Main Methods:

    • Diagnosis relies on patient history and local physical examination.
    • Treatment approaches include conservative and operative interventions.

    Main Results:

    • Acute anal fissures are managed conservatively with dietary changes, warm baths, and topical medications.
    • Nitrates, botulinum toxin, and surgery are considered for refractory or chronic cases.
    Keywords:
    anal fissure - conservative therapy - lateral sfincterotomy.

    Conclusions:

    • Conservative management is the first line for acute anal fissures.
    • Chronic anal fissures often necessitate surgical intervention after conservative measures fail.
