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.

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...

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:
Irritable Bowel Syndrome01:23

Irritable Bowel Syndrome

DefinitionIrritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by recurrent combinations of abdominal pain, bloating, diarrhea, or constipation.Pathophysiology of irritable bowel syndromeIts pathophysiology is multifactorial, involving disturbances in motility, sensory processing, microbial balance, barrier integrity, and gut–brain communication. These mechanisms interact to produce symptoms that vary across IBS subtypes.Altered Motility PatternsDisordered...
Irritable Bowel Syndrome I: Introduction01:17

Irritable Bowel Syndrome I: Introduction

Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...
Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Summary
This summary is machine-generated.

Internal rectal prolapse (IRP) is linked to reduced maximal resting pressure in the anal sphincter, impacting continence. Squeeze pressure remains unaffected, suggesting IRP primarily affects internal anal sphincter tone.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Pelvic Floor Disorders

Background:

  • Faecal incontinence is a common symptom in patients with internal rectal prolapse (IRP).
  • The precise mechanism linking IRP to faecal incontinence remains unclear.
  • Anal sphincter function is crucial for maintaining continence.

Purpose of the Study:

  • To investigate the relationship between internal rectal prolapse (IRP) and anal sphincter function.
  • To assess how the grade of rectal prolapse correlates with anal sphincter pressures.

Main Methods:

  • A prospective database of patients with internal rectal prolapse (IRP) and external rectal prolapse (ERP) was utilized.
  • Anorectal manometry data were analyzed to measure maximal resting pressure (MRP) and maximal squeeze pressure.
  • The correlation between prolapse grade and sphincter pressures was statistically evaluated.

Main Results:

  • A total of 515 patients were included in the study.
  • A significant reduction in mean maximal resting pressure (MRP) was observed with increasing grades of prolapse (grade 2 to 5).
  • Maximal squeeze pressure showed no consistent relationship with prolapse grade, except in patients with ERP where it was lower compared to IRP patients.

Conclusions:

  • This study demonstrates a significant association between internal rectal prolapse (IRP) and reduced maximal resting pressure (MRP).
  • The findings suggest that IRP contributes to incontinence primarily by decreasing internal anal sphincter tone.
  • Maximal squeeze pressure is not significantly affected by the grade of internal rectal prolapse.
