A Rat Model of Pouchitis Following Proctocolectomy and Ileal Pouch-Anal Anastomosis Using Dextran Sulfate Sodium
Published on: May 31, 2024
Summary
This systematic review evaluates non-surgical and surgical treatments for chronic anal fissures, common causes of anal pain. It synthesizes evidence on interventions like botulinum toxin and internal anal sphincterotomy for effectiveness and safety.
Area of Science:
- Gastroenterology
- Colorectal Surgery
Background:
- Anal fissures are a frequent cause of defecation-related anal pain.
- Low dietary fiber intake is a potential risk factor for anal fissures.
Purpose of the Study:
- To systematically review the effects of non-surgical treatments for chronic anal fissure.
- To systematically review the effects of surgical treatments for chronic anal fissure.
Main Methods:
- Systematic review of 28 studies including systematic reviews, RCTs, and observational studies.
- Searched major databases (Medline, Embase, Cochrane Library) up to August 2009.
- Included harms alerts from FDA and MHRA.
Main Results:
- Evaluated the quality of evidence for various interventions using GRADE methodology.
- Identified studies meeting inclusion criteria for effectiveness and safety analysis.
Conclusions:
- Presents information on the effectiveness and safety of interventions for chronic anal fissure.
- Interventions reviewed include anal advancement flap, dilation, botulinum toxin, calcium channel blockers, internal anal sphincterotomy, and nitric oxide donors.

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...

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.

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: 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...
Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
