Video rectosigmoscopy with chromoscopy (early diagnosis of cancer)

Videorectosigmoidoscopy with chromoscopy is an advanced endoscopic procedure used to examine the rectum and sigmoid colon. This technique enhances the visibility of the mucosal surface by applying special dyes during the procedure, allowing for the early detection of cancer, precancerous lesions, and other pathological changes. By improving the contrast on the mucosal surface, chromoscopy helps diagnose lesions that might be missed during standard endoscopy. In the "Dobrobut" medical network, experienced gastroenterologists utilize this method for the early diagnosis of cancer, enabling timely intervention and improved outcomes.

When to Consult a Doctor

Patients should consult a doctor and possibly undergo video rectosigmoidoscopy with chromoscopy if they experience any of the following symptoms:

Rectal bleeding: Any bleeding from the rectum, even if slight or episodic, warrants a diagnostic evaluation to exclude serious conditions.
Persistent diarrhea, constipation, or changes in stool composition may also indicate gastrointestinal pathology.
Prolonged abdominal pain, cramps, or discomfort that does not subside despite usual treatments requires further investigation.
Significant weight loss occurring without changes in diet or physical activity may indicate gastrointestinal tract disease.
Family history of colorectal cancer or other related cancers places patients at increased risk and may necessitate more frequent screening procedures, such as video rectosigmoidoscopy.

Indications and Contraindications

Video sigmoidoscopy with chromoscopy is a specialized endoscopic technique that enhances visualization of the rectum and sigmoid colon. The use of special dyes during the procedure improves identification of abnormal tissues or precancerous changes. It is indicated for:

Early-stage diagnosis of colorectal cancer.
Monitoring patients at high risk with inflammatory bowel diseases, prolonged ulcerative colitis, or Crohn's disease.
Hereditary cancer syndromes: Individuals with conditions such as Lynch syndrome or familial adenomatous polyposis may benefit from enhanced visualization techniques.
Assessment of previously identified lesions: polyps and other neoplasms.

In general, video rectosigmoidoscopy with chromoscopy is a valuable tool for early diagnosis and prevention of colorectal cancer, where it is most treatable.

Contraindications may include severe conditions, such as heart failure, acute gastrointestinal infections, and blood clotting disorders with a high risk of bleeding during the procedure.

Preparation

Preparation for video rectosigmoidoscopy with chromoscopy involves several key steps:

Detailed consultation, discussing the procedure, its goals, risks, and possible alternatives.
Dietary restrictions and bowel cleansing: Patients should follow a special diet and take laxatives to ensure a clear view of the colonic mucosa during the biopsy.
Adjustment of any medications that may affect blood clotting or interact with anesthesia, under the supervision of a doctor.

How the Procedure is Conducted

Video rectosigmoidoscopy with chromoscopy is a specialized diagnostic procedure used to examine the rectum and sigmoid colon using an endoscope with a camera and contrast agents (chromoscopy) to enhance visualization. The duration of this procedure may vary depending on several factors but typically takes about one hour.

During the procedure, sedation is used to ensure patient comfort and reduce discomfort. An endoscope is inserted into the bowel, and special dyes are applied to the mucosal surface to improve visualization of any abnormal areas. Using the endoscope, the doctor obtains a series of detailed images to identify suspicious lesions or abnormalities requiring further investigation. If problematic areas are found, a biopsy may be performed for further pathological study.

After the examination, the patient remains under observation for a period to monitor their condition following the procedure. Although the procedure is safe, potential complications include bleeding, adverse reactions to sedation, and, in rare cases, infection.

In the "Dobrobut" network, we aim to provide high-quality care during video rectosigmoidoscopy with chromoscopy. Our team of experienced specialists employs modern techniques to ensure a comfortable procedure and accurate diagnostics.
