Abstract:

This article defines diagnostic criteria, and reviews clinical evaluation and management of fecal incontinence, anorectal pain, dyssynergic defecation (DD), and rectal hyposensitivity and hypersensitivity. Diagnostic evaluation includes anorectal manometry, balloon expulsion test (BET), anal ultrasound, magnetic resonance imaging, defecography and neurophysiology testing. FI is defined as recurrent uncontrolled passage of fecal material for 3 months. Management includes antidiarrheals, Kegels exercise, biofeedback therapy, dextranomer injection, surgery, sacral nerve stimulation and translumbosacral neuromodulation therapy (TNT). Anorectal pain lasting seconds to minutes is defined as proctalgia fugax whereas pain lasting more than 30 minutes with puborectalis tenderness is defined as levator ani syndrome. Biofeedback and TNT may be useful. DD is defined by both symptoms of difficult defecation and objective evidence of dyssynergia. Biofeedback therapy is efficacious in DD. Rectal sensory disorders are defined by both anorectal symptoms and increased (hyposensitivity) or decreased (hypersensitivity) sensory thresholds during rectal balloon distension, and sensory biofeedback is useful.

Gastrointestinal Motility Disorders

Gastrointestinal Motility Disorders

Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Chronic Bowel Disorders: Introduction

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...

Other Disorders of Digestive System

Other Disorders of Digestive System

The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

Assessment of the Rectum and Anus

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,...

Inflammatory Bowel Disease V: Surgical Management

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 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...
