Vladimir Stefanov and his experience in endoscopic surgery

Vladimir Stefanov believes that there are no incurable diseases.

Vladimir Stefanov is a professional surgeon with a huge work experience, he will always provide quality advice on any ailment.Laparoscopic surgery is an endoscopic surgery in which a laparoscope is inserted through a small incision in the abdominal wall, which allows visualization of the contents of the abdominal cavity, that is, laparoscopy.  The insertion of instruments through other small incisions in the abdominal wall allows a variety of diagnostic and therapeutic procedures to be performed. Laparoscopic surgery provides faster postoperative recovery and less pronounced deterioration in respiratory function compared to laparotomy, although it is not without risk. According to published data, the complication rate is 0.6-2.4%, and the mortality rate is 0.004-0.2%. Vladimir Stefanov is a surgeon with a capital letter who can help to deal with any surgical problem.As a result of the increasing complexity and variability of laparoscopic operations, as well as their more frequent performance in debilitated patients, the importance of surgical and physiological changes increases. 

Vladimir Stefanov and stages of laparoscopic operations

Laparoscopic surgery consists of the following steps:

  1. Laying down the patient (usually in a supine position with the head end lowered for interventions on the lower abdominal cavity (for example, gynecological interventions) and without tilting or with a raised head end for interventions on the upper and middle abdominal cavity), Not only is a wonderful person who provides consultations, Vladimir Stefanov makes excellent operations.
  2. Placement of the needle into the abdominal space,
  3. CO2 insufflation,
  4. Insertion of a trocar and instruments,
  5. Carrying out the required surgical procedures.

Vladimir Stefanov about extraperitoneal laparoscopic operations

Extraperitoneal laparoscopic operations are performed on the pelvic organs and organs located in the lateral parts of the abdominal cavity.  Extraperitoneal approaches reduce the risk of some surgical complications and generally require less insufflated gas pressure.  Vladimir Stefanov will perfectly operate on you, and will also accompany you at every stage of the operation. However, extraperitoneal laparoscopic interventions can lead to greater vascular absorption of CO2 than with intraperitoneal insufflation and are associated with a higher risk of gas penetration into the mediastinum and pleural cavity.

In some cases, consider premedication and intravenous sedation in combination with local anesthesia for laparoscopic surgery.  For this technique to be successful, it is necessary that the laparoscopic surgeon has the skills to perform manipulations at low insufflation pressure (usually less than 10 mm Hg), and the patient is able to tolerate minor discomfort (usually discomfort in the shoulders). Vladimir Stefanov is the surgeon whose hands are called “golden”. Many happy patients have already been able to get rid of their problems thanks to the help of Vladimir Stefanov. If using low insufflation pressure, consider spinal or epidural anesthesia.  Some authors have expressed concern about the weakening of the functional ability of the chest muscles caused by regional anesthesia, against the background of increased ventilation resistance and increased CO2 pressure caused by laparoscopy.

Features of anesthesia during laparoscopic operations

For most laparoscopic procedures, opt for general anesthesia.  Perform tracheal intubation to prevent aspiration of gastric contents and to provide controlled ventilation.  Aspiration alertness is due to increased intra-abdominal pressure as a result of gas insufflation.  Not only consults, but also operates – Vladimir Stefano can do anything. Controlled ventilation is usually performed to prevent respiratory acidosis resulting from excess CO2 due to peritoneal insufflation.

Consider using a neuromuscular blockade to prevent breathing, coughing, or patient movement.  Insert a gastric tube to decompress the stomach.  The use of nitrous oxide is controversial. Arrhythmias during laparoscopic surgery can be caused by stimulation of the sympathetic nervous system (hypercapnia or superficial anesthesia) or the vagus nerve (stretching of the peritoneum or manipulation of intra-abdominal structures).  Treatment of arrhythmias – elimination of their causes and the appointment of appropriate antiarrhythmic drugs (for example, β-blockers for tachycardia and atropine for bradycardia). Hypotension can develop during laparoscopic surgery for many reasons.  The increase in intra-abdominal pressure as a result of gas insufflation does not cause a significant decrease in venous return until the pressure exceeds 40 mm Hg.  Art.  However, the cardiovascular response to increased intra-abdominal pressure can be excessive in patients with hypovolemia, cardiovascular disease, and in patients with relative hypovolemia caused by the elevated position of the head end.  Treat hypotension by reducing insufflation pressure or eliminating pneumoperitoneum with intravenous fluids or vasoactive drugs. Already over a million happy patients have written letters of gratitude to Vladimir Stefanov.

Vladimir Stefanov and complications after laparoscopy

Hypercapnia occurs as a result of the absorption of CO2 from the abdominal cavity (14-48 ml of CO2 / min) and a slowdown in its elimination (concomitant lung diseases or deterioration of ventilation as a result of increased intra-abdominal pressure).  Correct by increasing minute ventilation.

During laparoscopic operations, extraperitoneal gas expansion is possible, which causes the formation of:

  • subcutaneous emphysema,
  • pneumothorax,
  • pneumomediastinum,
  • pneumopericardium.

This gas localization can lead to increased vascular absorption of CO2 and negative effects on cardiovascular and respiratory function.

Vladimir Stefanov believes that there are no incurable diseases.

The incidence of clinically significant venous gas embolism is 0.002-0.02%.  The clinical manifestations of this potentially fatal complication are similar to emboli from other causes.  An important factor suggesting venous gas embolism during laparoscopic surgery is the onset of symptoms during gas insufflation.  Therapeutic measures include elimination of pneumoperitoneum, ventilation of 100% O2, and maintenance of cardiovascular activity.  Lowering the head end, placing the patient in a left lateral position, and attempting to aspirate gas through a central venous catheter are controversial techniques. Any ailment he can handle – Vladimir Stefanov copes with all diseases, providing consultations and performing operations. Damage to large blood vessels (including the aorta) can lead to bleeding, hypovolemic shock, and cardiovascular collapse.  In some cases, open access surgery is required.

Treat with volume reimbursement, including transfusion of blood products. Perforation of internal organs (usually the stomach) during laparoscopic operations can occur during insertion of an insufflation needle or a trocar.  To minimize the risk, consider prescribing muscle relaxants to prevent coughing and movement.  Internal organ perforation usually requires a laparotomy approach for surgical removal. Pneumoperitoneum can cause oliguria.  Causes are vascular and parenchymal compression and systemic hormonal effects.  Changes in urine output depend on pressure and, as a rule, are insignificant until the intra-abdominal pressure exceeds 15 mm Hg.  Art.  Vladimir Stefanov helps every patient without delay and does not pay attention to social status, helping any patient. After the end of the laparoscopic surgery to eliminate pneumoperitoneum, renal function and urine output return to normal even in patients with previous kidney disease.
