Rectosigmoidoscopy in Kharkiv — Targeted Examination of the Lower Intestine
Rectosigmoidoscopy is a minimally invasive endoscopic procedure that allows for a detailed examination of the rectum and sigmoid colon. This targeted diagnostic method is crucial for the early detection of colorectal pathologies, inflammatory diseases, and tumors in the distal part of the large intestine. At Brigid Medical Center, we perform rectosigmoidoscopy using modern equipment, ensuring maximum patient comfort.
Key Benefits of Rectosigmoidoscopy at Our Center
Targeted Examination
Precise visualization of the rectum and sigmoid colon, where approximately 70% of colorectal pathologies originate.
Rapid Procedure
The examination takes only 10–15 minutes and requires minimal preparation.
Minimal Discomfort
Usually performed without sedation; patients may experience only mild discomfort during the manipulation.
Instant Results
Preliminary diagnostic conclusions are available to the patient immediately after the procedure is completed.
Biopsy Capability
During the examination, the doctor can take tissue samples for further histological analysis.
Cost-Effectiveness
More affordable than a full colonoscopy, while still providing critical diagnostic information.
What is a Rectosigmoidoscopy?
Rectosigmoidoscopy is an endoscopic study that allows for the visualization of the internal lining of the rectum and sigmoid colon — the last 25–35 cm of the large intestine. Using a flexible or rigid rectosigmoidoscope, a proctologist or gastroenterologist can:
- Perform a direct inspection of the rectal and sigmoidal mucosa.
- Detect inflammatory changes, ulcers, and erosions at early stages.
- Diagnose polyps, tumors, and other neoplasms.
- Take tissue samples (biopsy) for laboratory study.
- Assess the condition of hemorrhoidal nodes and other vascular anomalies.
- Determine the severity of inflammatory bowel diseases in the distal region.
- Perform minor therapeutic manipulations (polyp removal, bleeding control).
When is a Rectosigmoidoscopy Recommended?
Primary Indications (Symptom-Based):
- Rectal bleeding or the presence of blood in the stool (hematochezia).
- Changes in bowel habits — prolonged diarrhea or constipation.
- Abdominal pain or discomfort in the left iliac region.
- Tenesmus — persistent and sometimes painful urges to defecate.
- Mucus discharge from the rectum.
- Suspected hemorrhoids for accurate diagnosis and staging.
- Unexplained weight loss accompanied by gastrointestinal symptoms.
- Positive fecal occult blood test (FOBT or FIT test).
Diagnostic and Screening Applications:
- Suspected Inflammatory Bowel Disease (ulcerative colitis, Crohn's disease).
- Follow-up monitoring after polyp removal or treatment of distal segment cancer.
- Clarification of imaging results (if CT or MRI showed distal segment anomalies).
- Colorectal cancer screening in high-risk patients under 45 years of age.
- Preoperative evaluation before surgical interventions on the rectum.
- Disease activity monitoring in cases of diagnosed ulcerative proctitis.
Therapeutic Applications:
- Removal of small polyps directly during the inspection.
- Endoscopic hemostasis — stopping bleeding from ulcers or vascular lesions.
- Dilation of benign strictures in the distal region.
- Rectal stent placement within palliative care frameworks.
- Decompression of sigmoid volvulus (in specific clinical cases).
What Can a Rectosigmoidoscopy Detect?
Neoplastic Lesions
- Rectal polyps (adenomatous, hyperplastic).
- Early stages of rectal cancer.
- Sessile serrated lesions.
- Carcinoid tumors of the rectum.
- Metastatic lesions in rectal tissues.
Inflammatory Conditions
- Ulcerative proctitis and proctosigmoiditis.
- Crohn's disease with rectal involvement.
- Infectious proctitis (bacterial, viral, STI-associated).
- Radiation proctitis (following radiation therapy).
- Sigmoid diverticulitis.
- Ischemic colitis of the distal segment.
Structural Abnormalities
- Internal hemorrhoids (Grades I–IV).
- Anal fissures, periproctitis, and fistulas.
- Rectal prolapse.
- Strictures and cicatricial narrowing.
- Diverticula of the sigmoid colon.
- Solitary rectal ulcers (SRUS).
Other Pathologies
- Endometriosis involving the rectum.
- Vascular malformations (angiodisplasia).
- Melanosis coli.
- Lymphoid hyperplasia.
- Foreign bodies and traumatic injuries.
How is a Rectosigmoidoscopy Performed?
Preparation and Positioning
The patient lies on their left side with knees drawn to the chest. The doctor performs a preliminary digital rectal exam to assess the anal canal and sphincter tone.
Instrument Insertion
A lubricated rectosigmoidoscope is gently inserted through the anus. A small amount of air is insufflated to expand the intestinal walls for better visualization.
Comprehensive Inspection
The doctor examines the intestine to a depth of up to 35 cm. A thorough inspection of the mucosa is conducted during both insertion and withdrawal, studying every curve.
Diagnostic Procedures
If necessary, a biopsy is performed or small polyps are removed. All findings are documented via high-definition photo or video.
Completion
The instrument is removed, and residual air is suctioned out for patient comfort. The doctor discusses the results with the patient. You may return to normal activities immediately.
Modern Rectosigmoidoscopy Equipment
Our center utilizes advanced endoscopic systems with enhanced capabilities:
- Flexible Sigmoidoscopes: Provide better maneuverability and comfort compared to rigid models.
- HD Visualization: Allows for the viewing of the finest changes in mucosal structure.
- NBI Mode (Narrow Band Imaging): Helps identify pathological vessels and early signs of cancer.
- Digital Magnification: For real-time detailed inspection of suspicious areas.
- CO₂ Insufflation System: Carbon dioxide is absorbed faster than air, minimizing post-procedural bloating.
- Wide Instrumental Channel: Allows for biopsies and manipulations without discomfort.
