Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
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,...
Appendicitis01:19

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
Drugs for Treatment of Diarrhea-Predominant IBS01:17

Drugs for Treatment of Diarrhea-Predominant IBS

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...
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...

Summary

Rectal endometriosis is a rare condition causing bowel obstruction in women of reproductive age. It requires consideration in the differential diagnosis of rectal stenosis due to its potential for significant narrowing.

Area of Science:

  • Gynecology
  • Gastroenterology
  • Surgical Pathology

Background:

  • Endometriosis is a common condition in reproductive-age women, typically affecting pelvic organs.
  • Bowel involvement, particularly circumferential rectal endometriosis, is infrequent.
  • Obstructive symptoms from rectal endometriosis can mimic inflammatory or malignant conditions.

Observation:

  • Two cases of women presenting with prominent intestinal obstruction due to rectal endometriosis are detailed.
  • One patient experienced obstructive symptoms requiring a decompressive colostomy, with diagnosis confirmed via laparoscopy and biopsy.
  • The second patient, previously treated for acute abdomen and a frozen pelvis, underwent rectosigmoidectomy for confirmed rectal endometriosis.

Findings:

  • Rectal endometriosis can lead to significant rectal stenosis and obstructive symptoms.
  • The condition, though rare, presents a diagnostic challenge due to overlapping symptoms with other rectal diseases.
  • Surgical intervention may be necessary to relieve obstruction and manage the disease.

Implications:

  • Highlights the importance of considering rectal endometriosis in the differential diagnosis of rectal stenosis in women of childbearing age.
  • Emphasizes the need for thorough evaluation to distinguish endometriosis from inflammatory or malignant causes of bowel obstruction.
  • Underscores the potential severity of rectal endometriosis, necessitating prompt diagnosis and management to prevent complications.
