Inflammatory Bowel Disease V: Surgical Management

755
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:

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

1.5K
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

839
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 II: Crohn's Disease

1.3K
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory Bowel Disease I: Ulcerative Colitis

1.2K
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

478
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Summary

A cat with chronic tenesmus caused by pelvic canal stenosis due to a malunited femur fracture experienced relief after a hindlimb amputation. This surgical intervention successfully resolved rectal compression and constipation without requiring a colectomy.

Area of Science:

  • Veterinary Surgery
  • Small Animal Medicine
  • Feline Orthopedics

Background:

  • Chronic tenesmus in cats can stem from complex orthopedic issues.
  • Pelvic canal stenosis secondary to femur malunion presents a diagnostic challenge.

Observation:

  • A 5-year-old domestic shorthair cat presented with a 13-month history of tenesmus and constipation.
  • Initial treatments including femoral head and neck excision did not resolve the clinical signs.
  • Abdominal radiographs and colonography revealed dynamic rectal compression exacerbated by femoral abduction.

Findings:

  • The rectal obstruction was dynamic, worsening with femoral abduction and improving with adduction.
  • A right hindlimb amputation was performed to alleviate the pelvic canal stenosis.
  • Post-amputation, the cat experienced immediate resolution of tenesmus and constipation.

Implications:

  • Hindlimb amputation can be a successful treatment for dynamic rectal compression caused by orthopedic malunions.
  • This approach avoids the need for more extensive procedures like subtotal colectomy.
  • Highlights the importance of considering dynamic mechanical obstruction in chronic constipation cases.
