Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

816
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...

Irritable Bowel Syndrome I: Introduction

1.1K
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...

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...

Inflammatory Bowel Disease V: Surgical Management

652
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 II: Crohn's Disease

1.2K
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 IV: Pharmacological Management

743
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
Pharmacologic...

Area of Science:

  • Surgical Technology
  • Medical Imaging
  • Computer-Aided Surgery

Background:

  • Objective intraoperative measurements are lacking in minimally invasive surgery, limiting standardization and documentation quality.
  • Quantitative Laparoscopy (QL) aims to address this by integrating objective measurements.
  • A novel tool for computer-assisted 3D bowel length measurement (BMS) was developed.

Purpose of the Study:

  • To develop and evaluate a computer-assisted 3D bowel length measurement (BMS) tool.
  • To enhance objective intraoperative measurements in minimally invasive surgery.
  • To apply BMS as a clinical tool within Quantitative Laparoscopy (QL).

Main Methods:

  • BMS processes 3D laparoscope images using computer vision algorithms.
  • Measurements are taken along a 3D reconstruction of the bowel surface.
  • Preclinical evaluation included phantom, ex vivo, and in vivo porcine models, followed by a clinical feasibility study.

Main Results:

  • In preclinical models, BMS showed a relative error between 3.7% and 7.2% for bowel length measurements.
  • BMS successfully measured bowel length in phantom, ex vivo, and in vivo porcine models.
  • The tool was successfully applied in a patient undergoing laparoscopic Roux-en-Y gastric bypass.

Conclusions:

  • Quantitative Laparoscopy (QL) using BMS is feasible.
  • The BMS tool successfully translated from preclinical models to a clinical setting.
  • BMS offers a potential solution for objective intraoperative bowel length measurement.
