About the department

K+31 employs endoscopist doctors with extensive experience in performing both high-quality diagnostics and a wide range of endoscopic therapeutic procedures, including under sedation (in sleep).

The endoscopy department provides highly effective diagnosis and treatment of diseases:

  • organs of the gastrointestinal tract (esophagus, stomach, small and large intestine),
  • pancreatobiliary zone (duct systems of the gallbladder and pancreas),
  • tracheobronchial tree.

The use of endoscopic examination techniques with magnification, in the mode of a narrow spectrum of light (NBI) and chromoscopy significantly expands the diagnostic capabilities, allowing you to see the slightest changes in the mucous membrane. Timely and efficiently performed endoscopy allows detecting changes in the early stages, thereby preventing the development of an advanced stage of diseases, including oncological ones.

Modern equipment at K+31 allows you to perform a high-quality study and create the most comfortable conditions for the patient, while minimizing the unpleasant sensations from the procedure. With increased sensitivity, fear, low pain threshold, we can conduct a study with anesthesia (sedation) under the supervision of a highly qualified team of anesthesiologists.

In K+31, the following types of diagnostics are carried out:

  • esophagogastroduodenoscopy (gastroscopy, or EGDS) - examination of the upper parts of the digestive tract (esophagus, stomach and duodenum);
  • colonoscopy - examination of the lower parts of the digestive tract (colon);
  • video capsule endoscopy and colonoscopy – examination of the small and large intestine using a small capsule with a video camera;
  • balloon-assisted (single-balloon) enteroscopy – examination of the small intestine with an enteroscope (special mirror);
  • endosonography (endoscopy) is a combination of ultrasound and endoscopic diagnostics. With the help of a video endoscope, ultrasound examination is performed directly through the wall of the organ (esophagus, stomach).

Endoscopic examination can be supplemented with:

  • biopsy - taking part of the mucous membrane for laboratory (histological) examination. It is performed during endoscopy using thin flexible instruments that are passed through a special channel of the device. The biopsy is painless, but may lengthen the procedure by several minutes;
  • chromoscopy - staining the mucous membrane of the examined organs using dyes. This technique allows you to more clearly examine the surface and dimple pattern of the mucous membrane, emphasize the contours of flat formations and the smallest depressions, allowing you to detect neoplasms at an early stage;
  • laparoscopic surgery - a low-traumatic procedure performed through small holes, without large incisions;
  • express test to determine the presence of Helicobacter pylori infection using the "Helpil-test" - the technique allows you to determine the presence of Helicobacter bacteria in the obtained biopsy specimen within a few minutes, which is the cause of a number of diseases.

Medical/surgical interventions

Doctors of K+31 clinics perform medical/surgical interventions through an endoscope using special instruments that are carried out through the instrument channel of the apparatus. Endoscopic operations are performed by us on an outpatient basis and in a hospital setting. In some cases, treatment avoids surgery.

Types of therapeutic endoscopic interventions K+31:

  • removal of foreign bodies from the stomach, small and large intestine, tracheobronchial tree;
  • stopping intraluminal bleeding using a wide range of endoscopic techniques (including their combinations);
  • removal of neoplasms (polyps, etc.) using modern endoscopic techniques, including the tunneling method;
  • oral endoscopic myotomy (POEM) for cardia achalasia;
  • ERCP (endoscopic retrograde cholangiopancreaticography) for diseases of the bile ducts and the main excretory duct of the pancreas;
  • installation of self-expanding stents for stenosing tumors and benign strictures of the gastrointestinal tract;
  • balloon dilatation of benign gastrointestinal strictures;
  • imposition of a percutaneous endoscopic gastrostomy (PEG);
  • endoscopic treatment of Zenker's diverticulum;
  • esophagogastroduodenoscopy (EGDS);
  • bronchoscopy;
  • ligation of varicose veins of the esophagus;
  • removal of gastrointestinal tract formations using loop electro excision techniques and endoscopic mucosal resection;
  • diagnostic and operative laparoscopy.

Research features

All endoscopic stands are provided with the ability to perform video recording of studies and image capture. Each protocol includes photographic images of the main anatomical areas and changes identified during the study; there is a video archive in the endoscopic database, which is very convenient for constantly observed patients.

Sterility of endoscopic procedures

Advanced endoscope processing techniques, as well as disposable consumables used in the K+31, prevent patients from becoming infected. Safety is also ensured by processing endoscopes in the company's automatic reprocessors using effective safe means. After processing, the endoscopes are placed in the system for drying and storage until next use. Transportation of endoscopes to the office is carried out using special containers providing aseptic conditions. These measures allow us to safely and safely perform endoscopic procedures at a professional and infectious-safe level!

Thank you very much to the K + 31 clinic and personally to Dr. Alexander Alexandrovich Gladyshev !! It was recommended to me by another doctor from KB 62. Doctor Gladyshev performed diagnostic bronchoscopy for me for papillomatosis of the larynx and trachea (under local anesthesia). Took a biopsy of papillomas. Everything was very neat ... Then he explained everything in detail and intelligibly. After receiving the results of the histological examination, Dr. Gladyshev performed two endoscopic operations for me under general anesthesia - removal of papillomas. Everything went well. I was very pleased with everything: the reception, quality, high professionalism of the doctor, the result of treatment and the clinic as a whole! Thank you very much!!!
A brilliant doctor and a very delicate person! I performed the procedure impeccably, and did not notice anything. Ugh, ugh, ugh! Next time only to him. There would be more such doctors. Good luck, dear Denis Evgenievich!
Denis Evgenievich, thank you very much, you and your team Doctors with a capital letter! I wish you success in your hard work! Denis Evgenievich, performed two endoscopy manipulations for me in September 2020 and a calonoscopy under sanitation, all at the highest level. I recommend this doctor to everyone. Do not be ill.
Doctor Seleznev Denis Evgenievich was advised to me by my friend, who had previously operated on with him. I didn’t regret a bit that I used his services, since I hadn’t met a great professional in her field for a long time. He not only carried out the operation successfully, but also charged me with a positive attitude before it, and also explained all the details. I cannot fail to note the well-coordinated work of both the specialists who helped him with the operation, and the team of nurses who helped me in postoperative rehabilitation. Denis Evgenievich thank you very much !!! You are a doctor with a BIG letter !!!

I want to say a huge maternal thanks to Dr. Alexander Gladyshev for his competent and qualified, and no less important human participation in the fate of my son. The doctor performed bronchoscopy and found a tumor of the left bronchus in a very difficult place, took the correct histological material and stopped the bleeding. After 1.5 The son was operated on for a month, but the tumor never bled during this period. The son was operated on in England, at the Cambridge hospital. The doctors noted the high qualifications of the bronchoscopy and histological results (these examinations were not redone before the operation, and the materials were sent via the Internet) Thanks again Dr. Gladyshev A.A., his professionalism is deeply respected.

I want to say a huge thank you both to the K + 31 clinic and directly to Alexander Alexandrovich Gladyshev for the operations performed on me, for consultations in the postoperative period, and for the many years he has done to restore my larynx !!!! It just so happened that I was diagnosed with recurrent papilomatosis of the larynx, for a long time I was observed at the Herzen Institute, but my path led me to this wonderful clinic, where, for example, it is much more convenient for me to make an appointment with a doctor and come to him for an appointment, and I also want say a big thank you to all the medical staff, and anesthesiologists !!!!

Thank you very much! To be honest, I was afraid to go for a gastroscopy, but you performed it as comfortably as possible. And a special thank you for your patience and support during the procedure. It is good when the doctor does not forget that the patient is a living person, and not just an object of research. Thanks again!

I am pleased with the visit to the clinic K + 31 and the result of the study. Although not a very good diagnosis was made, at least it was made and I started treatment. In another clinic, they could not even do this, although I did analyzes there and examinations of all kinds for ten years in advance! And at K + 31, doctor Fedorov did everything clearly, he wrote down the examination to the smallest detail (I did a capsule endoscopy of the colon), the treatment was prescribed and I began to feel much better. Thank!
