Enterocele is a type of pelvic organ prolapse where small intestine descends into the pelvis. It most often bulges into the space between the rectum and vagina (rectovaginal space). It is commonly discussed in urogynecology, colorectal surgery, and pelvic floor clinics. In gastroenterology (GI) practice, it matters because it can contribute to difficult defecation and pelvic pressure symptoms.

Rectocele is a form of pelvic organ prolapse where the rectum bulges toward the vagina. It reflects weakening of the tissue layer between the rectum and the vagina (the rectovaginal septum). Rectocele is most often discussed in colorectal surgery, gastroenterology pelvic floor clinics, and urogynecology. Clinically, it is used as a descriptive diagnosis when evaluating obstructed defecation or pelvic floor symptoms.

Pelvic Floor Dysfunction describes abnormal function of the pelvic floor muscles and supporting structures. It commonly affects bowel control, defecation (passing stool), and anorectal comfort. In gastroenterology, it is often discussed in constipation, fecal incontinence, and anorectal pain syndromes. It is used as a clinical framework to guide focused testing and conservative therapies.

Biofeedback Therapy is a behavioral treatment that uses real-time body signals to teach patients how to change specific physiologic functions. It translates internal processes (like muscle activity) into visual or audio feedback that a person can understand and practice with. In gastroenterology, it is commonly used for pelvic floor and anorectal disorders that affect defecation and continence. It may also be used in selected functional gastrointestinal conditions where learned patterns contribute to symptoms.

Anorectal Manometry is a physiologic test that measures pressures and reflexes in the rectum and anal canal. It helps clinicians understand how the pelvic floor and anal sphincters work during continence and defecation. It is commonly used in gastroenterology, colorectal surgery, and pelvic floor clinics. It is often paired with other tests that assess bowel function and evacuation.

Defecography is an imaging test that evaluates how the rectum and pelvic floor work during defecation. It records real-time changes in anatomy while a person attempts to empty the rectum. It is commonly used in gastroenterology and colorectal surgery to investigate difficult or incomplete bowel movements. It can be performed using fluoroscopy (X-ray) or magnetic resonance imaging (MRI).

A Colon Transit Study is a diagnostic test that measures how quickly material moves through the large intestine (colon). It is most commonly used to evaluate constipation and suspected bowel motility disorders. The study estimates “transit time,” meaning the time it takes for contents to travel from the stomach to the rectum. It is often ordered in outpatient gastroenterology and colorectal surgery clinics.

Achalasia Type III is a subtype of achalasia defined by abnormal, spastic contractions in the esophagus. It describes a specific pattern seen on high-resolution manometry, a test that measures esophageal pressure and motility. In plain terms, the lower esophageal sphincter does not relax normally, and the esophageal body squeezes in an uncoordinated, high-pressure way. It is commonly used in gastroenterology to classify achalasia and guide discussions about management options.

Achalasia Type II is a subtype of achalasia, a disorder where the esophagus has trouble moving food into the stomach. It is defined using high-resolution manometry, a test that measures pressure and muscle function in the esophagus. In Achalasia Type II, the lower esophageal sphincter does not relax well and the esophagus pressurizes as a unit. Clinicians use this label mainly to standardize diagnosis and to help frame treatment discussions and prognosis.

Achalasia Type I is a manometry-based subtype of achalasia, sometimes called “classic achalasia.” It describes a pattern where the lower esophageal sphincter (LES) does not relax normally and the esophageal body shows absent peristalsis. In plain terms, the esophagus does not squeeze food downward effectively, and the valve into the stomach does not open well. It is most commonly used in gastroenterology when interpreting high-resolution manometry (HRM) studies.
