Intestinal Obstruction I: Introduction01:29

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,...
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,...
Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

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:
Inflammatory Bowel Disease I: Introduction01:26

Inflammatory Bowel Disease I: Introduction

Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows “skip lesions” in which...
Diverticular Disease of the Colon01:27

Diverticular Disease of the Colon

Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Diagnostic Imaging

Background:

  • Rectoanal intussusception (RI) is a telescoping of the rectal wall during defecation, often identified on defecography.
  • The etiology of RI is debated, with hypotheses suggesting it as a primary disorder or a secondary phenomenon.
  • Clinical symptoms of obstructive defecation may indicate RI, necessitating accurate diagnosis.

Purpose of the Study:

  • To review the diagnostic modalities for rectoanal intussusception.
  • To discuss the controversial management strategies for RI.
  • To provide an overview of current understanding regarding RI etiology.

Main Methods:

  • Defecography is the gold standard for diagnosing RI.
  • Dynamic pelvic magnetic resonance imaging (DPMRI) and transperineal ultrasound are alternative imaging techniques.
  • Review of existing literature on RI etiology, diagnosis, and management.

Main Results:

  • RI is a recognizable physiologic finding on defecography.
  • Diagnostic accuracy of DPMRI and transperineal ultrasound is currently limited compared to defecography.
  • Management options range from conservative (biofeedback) to surgical (Delorme, rectopexy, STARR).

Conclusions:

  • While defecography is definitive for RI diagnosis, alternative imaging has lower sensitivity.
  • Management strategies for RI vary in efficacy and are subject to ongoing debate.
  • Further research is needed to clarify RI etiology and optimize treatment outcomes.
