Insights

Intestinal myiasis, caused by ingesting fly larvae, can present as a severe rectal mass. This rare case required surgical intervention and highlights the importance of hygiene in preventing such invasive infections.

Area of Science:

  • Gastroenterology
  • Parasitology
  • Surgical Pathology

Background:

  • Intestinal myiasis is typically a benign, asymptomatic condition resulting from ingesting food or water contaminated with fly eggs or larvae.
  • Symptoms are usually mild and transient, often resolving without specific treatment.

Observation:

  • A rare case of invasive intestinal myiasis presented with severe symptoms including rectal pain, bloody mucous discharge, and passage of maggots.
  • Proctoscopy revealed an irregular, fungating rectal mass infested with maggots in the rectum and anal canal.
  • Histopathology confirmed numerous larvae at various developmental stages within an inflamed and necrotic bowel wall, with no evidence of malignancy.

Findings:

  • The invasive intestinal myiasis mimicked a rectal tumor, necessitating surgical intervention.
  • Surgical management involved excision of the affected tissue and a diversion colostomy.
  • Post-operative treatment included hygiene measures, vermicides, anti-inflammatories, and purgatives, leading to recovery after colostomy closure.

Implications:

  • This case underscores that intestinal myiasis can manifest as a significant mass lesion requiring surgical management, challenging its typical asymptomatic presentation.
  • It highlights the critical role of public and personal hygiene in preventing the ingestion of contaminants that lead to parasitic infections.
  • The successful outcome emphasizes the importance of prompt diagnosis and appropriate multidisciplinary treatment for invasive intestinal myiasis.

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.

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...
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...
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...
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,...
