Enterocele: Definition, Uses, and Clinical Overview

Posted on February 28, 2026 | by drgastroenterologist

Enterocele Introduction (What it is)

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.

Why Enterocele used (Purpose / benefits)

Enterocele is not a medication or device; it is a diagnostic term that helps clinicians describe a specific anatomic problem in pelvic support. Using the term precisely is beneficial because pelvic floor disorders often overlap, and symptoms can come from multiple compartments (anterior, apical, posterior).

In clinical care and education, Enterocele is used to:

Clarify anatomy: It differentiates descent of small bowel from other prolapse findings such as rectocele (rectal wall bulge), cystocele (bladder bulge), or uterine/vaginal vault prolapse.
Frame symptom evaluation: It provides a structured explanation for symptoms that may include pelvic heaviness, a vaginal bulge sensation, or defecatory dysfunction (difficulty emptying).
Guide diagnostic testing: When physical examination is inconclusive, the suspicion of Enterocele can shape the choice of dynamic imaging (for example, defecography or dynamic pelvic magnetic resonance imaging).
Support treatment planning: Management varies by patient goals, comorbidities, and coexisting pelvic floor disorders. Naming Enterocele helps teams plan conservative versus surgical approaches and coordinate among specialties.
Improve interdisciplinary communication: GI clinicians, pelvic floor physical therapists, gynecologists, and colorectal surgeons often evaluate related complaints. A shared term reduces ambiguity when documenting findings and discussing next steps.

Clinical context (When gastroenterologists or GI clinicians use it)

Although Enterocele is primarily a pelvic floor diagnosis, GI clinicians encounter it in settings where bowel symptoms overlap with pelvic support disorders, especially in patients referred for constipation or obstructed defecation.

Typical scenarios include:

Chronic constipation with obstructed defecation symptoms, such as incomplete evacuation or the need for prolonged straining
Defecatory disorders evaluated in a pelvic floor or motility clinic, where pelvic anatomy and coordination are assessed together
Patients with multiple pelvic floor problems (for example, rectocele plus suspected Enterocele) where symptoms do not match a single finding
Preoperative or postoperative discussions in patients undergoing colorectal surgery (especially operations affecting pelvic anatomy) or gynecologic surgery
Interpretation of defecography or dynamic pelvic imaging reports that mention Enterocele or related findings (such as sigmoidocele)
Multidisciplinary assessment of pelvic pain/pressure symptoms when gastrointestinal, urinary, and gynecologic symptoms overlap

Contraindications / when it’s NOT ideal

Because Enterocele is a condition rather than a test, “contraindications” apply most directly to specific diagnostic studies or treatments that may be used when Enterocele is suspected or confirmed. Suitability varies by clinician and case.

Situations where a given approach may be less suitable include:

Imaging constraints
Magnetic resonance imaging (MRI) may be less feasible in some patients due to scanner limitations, implanted devices that are not MRI-compatible, or severe claustrophobia (varies by material and manufacturer).
Fluoroscopic defecography uses ionizing radiation; clinicians may prefer alternatives in situations where radiation avoidance is prioritized.
Exam limitations
A standard pelvic exam may not fully demonstrate Enterocele if prolapse is intermittent, position-dependent, or masked by other compartment defects.
Non-operative vs operative considerations
Surgery may be deferred or avoided in patients with medical instability, uncontrolled infection, or limited ability to tolerate anesthesia (varies by clinician and case).
Mesh-based repairs may be avoided in some settings due to patient-specific factors or surgeon preference; the appropriate material and approach vary by clinician and case.
Symptom mismatch
If symptoms are mild or primarily driven by a different diagnosis (for example, slow-transit constipation or irritable bowel syndrome), focusing on Enterocele may not be the most helpful framework.

How it works (Mechanism / physiology)

Enterocele reflects a failure of pelvic support that allows the peritoneal sac (and often small bowel loops) to descend into the pelvis, typically between the rectum and vagina.

High-level mechanism

Support structures weaken or stretch: The pelvic floor is supported by muscles (notably the levator ani), connective tissue, and fascial attachments. Over time, these supports may weaken.
Intra-abdominal pressure transmits downward: Repeated or sustained pressure (from coughing, straining, heavy lifting, pregnancy-related changes, or other causes) can contribute to descent of pelvic contents.
Herniation into the rectovaginal space: In many cases, small bowel and peritoneum descend posteriorly toward the vaginal canal, creating a bulge and altering pelvic geometry.

Relevant anatomy (GI and pelvic floor)

Small intestine: The “entero-” portion of Enterocele refers to bowel, usually small bowel.
Peritoneum: A peritoneal sac may form the leading component of the prolapse; sometimes bowel is present, sometimes the sac predominates.
Rectum and anal canal: The posterior compartment is involved, and rectal emptying mechanics can be affected even when the rectum itself is structurally normal.
Pelvic floor muscles: Coordinated relaxation of the pelvic floor and anal sphincters is needed for defecation. Structural prolapse can coexist with dyssynergic defecation (incoordination), complicating symptoms and interpretation.

Clinical interpretation and time course

Enterocele can be dynamic: it may be minimal at rest and more evident with Valsalva (bearing down), standing, or during defecation.
Symptoms are not perfectly proportional to the degree of descent. Some patients with notable prolapse have few symptoms, while others are highly symptomatic.
Reversibility depends on the underlying contributors and chosen management strategy; outcomes and durability vary by clinician and case.

Enterocele Procedure overview (How it’s applied)

Enterocele is not a single procedure. Clinically, it is assessed and then managed using conservative measures, devices, pelvic floor therapy, and/or surgery depending on severity and goals. A general workflow is outlined below.

History and symptom characterization – Pelvic pressure or heaviness, bulge sensation – Bowel symptoms (constipation, incomplete evacuation, positional or effort-related worsening) – Urinary or sexual symptoms that may suggest multi-compartment involvement – Prior pelvic surgeries (including hysterectomy), obstetric history, and factors increasing abdominal pressure
Physical examination – Pelvic exam to evaluate compartment prolapse (often using standardized staging systems) – Rectal exam when defecatory symptoms are prominent – Assessment for coexisting rectocele, cystocele, or apical prolapse
Labs (selected, not routine for diagnosis) – Laboratory testing is not typically diagnostic for Enterocele itself. – Labs may be used to evaluate associated issues (for example, anemia if bleeding symptoms exist from another cause), based on clinical context.
Imaging / diagnostics (when needed) – Dynamic pelvic imaging may be used when exam findings are unclear or symptoms suggest complex pelvic floor dysfunction. – Common options include fluoroscopic defecography and dynamic pelvic MRI; technique choice varies by center and clinical question.
Preparation (if testing or intervention is planned) – Preparation depends on the study (for example, contrast placement for defecography) or surgery (preoperative assessment and planning). Specific protocols vary.
Intervention / management (broad categories) – Conservative approaches may include pelvic floor physical therapy and/or a pessary in appropriate patients (chosen and fitted by qualified clinicians). – Surgical approaches may be considered for more significant symptoms or prolapse, often with attention to repairing apical support and addressing coexisting defects.
Immediate checks and follow-up – Follow-up focuses on symptom response, detection of persistent or new compartment defects, and management of bowel function and pelvic floor coordination. – Recurrence risk and durability vary by technique, tissue quality, and patient factors.

Types / variations

Enterocele can be described in multiple clinically useful ways. The terminology may differ across radiology, gynecology, and colorectal surgery reports.

Common variations include:

Primary (de novo) vs secondary
Primary: develops without prior pelvic surgery, often alongside generalized pelvic floor laxity.
Secondary: occurs after pelvic surgery, commonly discussed after hysterectomy when vaginal vault support changes.
By anatomic compartment emphasis
Often considered part of apical/posterior compartment prolapse because it involves descent near the vaginal apex and posterior vaginal wall.
By herniated content
True Enterocele: small bowel is present within the prolapsing sac.
Peritoneocele: a peritoneal sac without clear bowel content may be described; naming conventions vary by radiologist and case.
Sigmoidocele: the sigmoid colon is the main herniating structure, which may be discussed alongside Enterocele in defecography reports.
By clinical behavior
Occult/dynamic: visible mainly during straining or defecation maneuvers on imaging.
Fixed: evident on routine examination without provocative maneuvers.
By management approach
Conservative management: symptom-focused strategies, pelvic floor therapy, and/or pessary use (when appropriate).
Surgical repair: vaginal, abdominal, or minimally invasive approaches; native tissue versus mesh-augmented techniques may be considered depending on patient factors and surgeon experience (varies by clinician and case).

Pros and cons

Pros:

Provides a precise term for a specific pelvic floor anatomic defect
Helps explain obstructed defecation symptoms when pelvic support failure contributes
Promotes structured evaluation of multi-compartment pelvic floor disorders
Guides selection of dynamic imaging when the physical exam is inconclusive
Supports interdisciplinary planning across GI, urogynecology, and colorectal surgery
Helps set expectations that symptoms may reflect both structure (prolapse) and function (coordination)

Cons:

Symptoms can overlap with other conditions, so Enterocele may be over-attributed without full evaluation
Physical exam findings may miss dynamic prolapse, leading to underdiagnosis in some cases
Imaging interpretation depends on technique and patient effort; results can vary across centers
Often coexists with other pelvic floor disorders, complicating symptom-to-structure matching
Management choices can be complex and individualized, with variable durability and recurrence risk
Terminology (enterocele vs peritoneocele vs sigmoidocele) may be inconsistently used across reports

Aftercare & longevity

Aftercare and “longevity” depend on whether Enterocele is managed conservatively or surgically, and on whether coexisting pelvic floor dysfunction is addressed. Outcomes are influenced by anatomy, pelvic floor muscle function, bowel habits, and comorbidities; durability varies by clinician and case.

General factors commonly discussed in follow-up include:

Severity and multi-compartment prolapse: Persistent symptoms may reflect untreated associated prolapse (for example, rectocele or apical prolapse) or functional defecatory disorders.
Pelvic floor coordination: Even after anatomic support is improved, dyssynergic defecation can continue to drive constipation symptoms unless identified and addressed.
Nutrition and stool consistency: Clinicians often monitor stool form and straining because excessive straining can worsen pelvic floor symptoms; specific recommendations are individualized.
Comorbidities that increase abdominal pressure: Chronic cough, ascites, or severe constipation can affect symptom persistence and recurrence risk.
Follow-up adherence: Ongoing assessment can help distinguish recurrent prolapse from other causes of pelvic discomfort or bowel symptoms.
Technique/material choices (when surgery is performed): Approach and materials can influence recovery profile and recurrence risk; selection varies by clinician and case.

Alternatives / comparisons

Because Enterocele is a diagnosis, “alternatives” generally refer to alternative explanations for symptoms, alternative ways to confirm the diagnosis, or alternative management strategies.

Common comparisons include:

Observation/monitoring vs active intervention
Monitoring may be reasonable when symptoms are minimal and quality of life impact is low.
Active intervention may be considered when symptoms are more disruptive or when complications of prolapse are present; thresholds vary by clinician and case.
Pelvic floor physical therapy vs surgery
Physical therapy focuses on muscle function, coordination, and symptom management, which can be important when functional defecation disorders coexist.
Surgery targets anatomic support. It may improve bulge symptoms but does not automatically resolve all bowel symptoms, especially when motility or coordination problems are present.
Pessary use vs surgical repair
A pessary is a non-surgical option used in some patients to support pelvic organs; fitting and tolerance vary.
Surgical repair aims for longer-term anatomic correction but includes operative and recovery considerations.
Fluoroscopic defecography vs dynamic pelvic MRI
Defecography can visualize evacuation mechanics during simulated defecation.
Dynamic MRI offers multi-compartment soft-tissue detail without ionizing radiation. Availability and protocols vary by center, and interpretation can differ.
Enterocele vs rectocele (symptom overlap)
Both can contribute to obstructed defecation and a sense of incomplete emptying.
Rectocele involves the rectal wall bulging; Enterocele involves small bowel/peritoneum descending between rectum and vagina. They may coexist, and separating contributions can be challenging.

Enterocele Common questions (FAQ)

Q: Is Enterocele a GI disease or a pelvic floor problem?
Enterocele is primarily a pelvic floor support disorder, not a disease of the intestinal lining. GI clinicians still encounter it because it can affect defecation mechanics and overlap with constipation or obstructed defecation symptoms.

Q: What symptoms are commonly associated with Enterocele?
Symptoms may include pelvic pressure, a vaginal bulge sensation, discomfort that worsens with standing or straining, and difficulty emptying the rectum. Some people have minimal symptoms despite visible prolapse, and symptom severity does not always match imaging findings.

Q: Does Enterocele cause constipation?
It can contribute to constipation-like symptoms, especially a sense of blockage or incomplete evacuation. However, constipation has many causes, including motility disorders and dyssynergic defecation, so clinicians typically evaluate for multiple contributors.

Q: How is Enterocele diagnosed?
Diagnosis often starts with history and pelvic examination, sometimes with standardized prolapse staging. If symptoms suggest a dynamic problem or the exam is inconclusive, clinicians may use studies such as defecography or dynamic pelvic MRI, depending on local practice.

Q: Is imaging always necessary?
No. In some cases, physical exam findings and symptoms are sufficient to support a clinical diagnosis. Imaging is more commonly used when symptoms are complex, when multiple pelvic floor disorders are suspected, or when surgical planning requires detailed anatomic information.

Q: Is Enterocele painful?
Pain is not required for the diagnosis. Some patients report pressure, heaviness, or discomfort, while others notice mainly a bulge or bowel-emptying difficulty; pelvic pain can also come from other gynecologic, urologic, musculoskeletal, or GI conditions.

Q: Does evaluation or treatment involve anesthesia or sedation?
Routine pelvic exams do not require sedation. Imaging studies typically do not require sedation, though protocols vary. Surgical repair, when performed, generally involves anesthesia, with the specific type depending on the approach and patient factors.

Q: Do I need to fast before testing?
Fasting requirements depend on the specific test and facility protocol. Many pelvic floor imaging studies have tailored preparation instructions, which vary by center and case.

Q: How long do results or benefits last after treatment?
With conservative measures, symptom control may persist as long as contributing factors are managed and the approach remains tolerable. After surgery, durability depends on tissue quality, technique, coexisting pelvic floor dysfunction, and individual risk factors; recurrence risk varies by clinician and case.

Q: What is the cost range for evaluation or treatment?
Costs vary widely by country, health system, insurance coverage, imaging modality, and whether surgery is performed. Facility fees, professional fees, and anesthesia-related costs (when applicable) can all contribute.

Q: How soon can someone return to work or school after treatment?
Return timelines differ based on whether management is conservative or surgical, the type of procedure, and the physical demands of daily activities. Clinicians typically individualize recommendations to the patient’s recovery and job requirements rather than using a single universal timeline.
