EXPERIMENTAL SUBSTANTIATION AND CLINICAL APPLICATION OF MICROSURGICAL ANTIREFLUX GASTROINTESTINAL ANASTOMOSES IN
Summary
New microsurgical techniques for gastrointestinal anastomosis improve stomach reconstruction, creating anti-reflux properties and preserving sphincter function. These methods enhance durability and minimize tissue trauma for better patient outcomes.
Area of Science:
- Surgical Innovation
- Gastroenterology
- Microsurgery
Background:
- Reconstructive surgery for the stomach aims to improve outcomes after gastric procedures.
- Development of gastrointestinal anastomosis techniques is crucial for restoring digestive function.
- Existing methods may lead to complications like duodenal reflux.
Purpose of the Study:
- To develop and evaluate new microsurgical gastrointestinal anastomosis techniques with sphincter properties.
- To improve the outcomes of reconstructive stomach operations.
- To create anti-reflux anastomosis for enhanced gastric surgery.
Main Methods:
- Experimental study on 60 animals and 52 human organ complexes.
- Development of four novel microsurgical anastomosis techniques, including pilorus-preserving gastrectomy and artificial sphincter formation (patents obtained).
- Clinical testing in 20 patients undergoing gastric resection with the new anastomosis techniques.
Main Results:
- Anatomical studies confirmed high impermeability, durability, and preservation of tissue histotopography with microsurgical anastomosis.
- Clinical follow-up (1-6 years) showed good sphincter function and absence of duodenal reflux in operated patients.
- Microsurgical techniques demonstrated minimal tissue trauma and precise adaptation of tissue layers.
Conclusions:
- Microsurgical techniques enable the creation of anti-reflux gastrointestinal anastomosis with preserved sphincter function.
- These methods offer a minimally invasive approach to gastric reconstruction.
- The developed techniques improve functional outcomes and reduce complications after gastric surgery.

01:19Anastomoses
2.9K
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.

01:19Clinical Applications of Epidermal Stem Cells
3.3K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
1.5K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

01:16Gastric Emptying
3.8K
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...
