Endoscopic Removal of Gastrointestinal Tract Lesions

Endoscopic removal of gastrointestinal (GI) tract lesions is a modern, minimally invasive treatment method that allows the removal of polyps, benign tumors, certain types of early-stage malignant neoplasms, and other pathological changes of the mucous membrane without open surgery. At the Horizons Clinic, this procedure is performed by experienced physicians using state-of-the-art equipment. You receive precise, efficient treatment with a comfortable recovery period.

Service Description

Endoscopic removal of GI lesions is performed using an endoscope — a thin, flexible instrument equipped with an optical system and specialized tools, inserted through the mouth or rectum. During the procedure, the physician introduces the endoscope into the gastrointestinal tract and removes detected abnormalities under visual guidance.
Depending on the size and location of the lesion, different techniques may be used, including:

  • Endoscopic polypectomy of varying levels of complexity;
  • Endoscopic mucosal resection (EMR);
  • Endoscopic submucosal dissection (ESD);
  • Submucosal tunneling endoscopic resection (STER);
  • Endoscopic full-thickness resection (FTER).

The procedures are performed under sterile conditions with general sedation, anesthesia, or short-term medicated sleep, ensuring comfort and a painless experience. The built-in endoscopic video system magnifies the image, enabling highly precise and safe lesion removal while preserving healthy tissue.
After removal, the lesion is always sent for histological examination, which helps determine its nature and whether additional treatment or monitoring is required.

Indications:

  1. Polyps of the esophagus, stomach, duodenum, or colon;
  2. Benign flat mucosal tumors;
  3. Early-stage gastrointestinal cancers that have not invaded deeper layers of the organ wall;
  4. Submucosal GI tumors;
  5. Cystic lesions suitable for minimally invasive treatment;
  6. Tumors causing bleeding or obstructing the passage of food or stool;
  7. Need to remove suspicious lesions for histological examination.

Contraindications:

  1. Severe blood clotting disorders;
  2. Serious overall patient condition in which any intervention poses a significant risk;
  3. Perforation of the stomach or intestine, acute peritonitis;
  4. Large malignant tumors requiring extensive surgical removal;
  5. Acute infectious diseases accompanied by high fever.

Advantages

  • A team of highly experienced endoscopic surgeons and anesthesiologists;
  • Minimal trauma — no large incisions or damage to healthy tissue;
  • Fast recovery — most patients return to their normal lifestyle the next day after the procedure;
  • High safety standards — use of disposable endoscopic instruments and advanced energy systems;
  • High precision — modern high-resolution surgical endoscopes;
  • Diagnosis and treatment in one procedure — lesions are removed immediately and sent for histological analysis;
  • Lower risk of complications compared to open surgical procedures.

FAQs

No. In most cases, endoscopic lesion removal is performed under sedation or anesthesia, so the patient does not experience discomfort.

The duration ranges from 20 minutes to 4 hours, depending on the size, number, and location of lesions, as well as the complexity of access.

Usually not. Most patients can return home on the same day as the procedure. However, in some cases, short-term inpatient observation (1–2 days) may be recommended.

Yes. Before removal of lesions in the esophagus, stomach, or duodenum, patients should avoid food for 6 hours and liquids for 4 hours before the procedure. For colon procedures, bowel cleansing according to a special preparation protocol is required. During the consultation, the doctor will determine which tests are necessary before the procedure.

How Is Endoscopic Removal of GI Lesions Performed?

The procedure is carried out in several stages:
  • Anesthesia or sedation — ensures comfort and a painless experience.
  • Endoscope insertion — through the mouth or rectum, depending on the lesion location.
  • Visualization and assessment of the lesion — the doctor examines the mucosa and determines the optimal removal technique.
  • Lesion removal — specialized loops, knives, and coagulation devices are used. If necessary, mucosal or submucosal resection is performed.
  • Hemostasis control — bleeding is stopped using clips, coagulation, or injections.
  • Specimen retrieval and histological examination — the removed material is sent for laboratory analysis.

After anesthesia, short-term post-procedure observation is required. The patient remains under medical supervision until full recovery of consciousness following sedation.
