Summary
of the dissertation work of Dzhumabekov Berik Nuraddinovich on the topic:
«Prevention of gastrointestinal anastomosis failure in emergency
surgery»
for the degree of Doctor of Philosophy (PhD) in the specialty
6D110100 – Medicine
The relevance of the problem
The incidence of intestinal anastomosis failure in emergency surgery,
according to various authors, ranges from 6 to 40%, where the postoperative
mortality rate can reach up to 40%.
The main etiological factors in the development of this postoperative
complication are considered to be:
high intraluminal pressure, change in the
functioning of the microcirculation of the intestinal wall, development of hypoxic
changes in the tissues of the intestinal wall and formation of infectious processes in
the peritoneal cavity with the participation of highly virulent microorganisms.
Based on these factors, the correct choice of
suture materials, increasing the
mechanical strength and tightness of the anastomosis, as well as the use of existing
methods of decompression and drainage of the intestinal lumen in the area of the
anastomosis play an important role in the prevention of intestinal anastomosis
failure.
Auto-plasma is a natural source of signaling molecules; after platelet
activation, their granules degranulate and release
cytokines that modify the
pericellular microenvironment.
Today, the question of cellular response in relation to wound regeneration is
becoming more and more popular. Platelets are the first type of blood cells
responding to a wound and are also known to promote tissue repair through the use
of growth factors and other active substances.
The growth factors possessed by platelets are usually attributed to the group
of polypeptide molecules. These molecules have different structures and have
different mechanisms of action, which may be associated with different mitogenic
and chemotactic properties. As you know, these properties are fundamental in
wound healing.
It should be noted that many experimental
studies related to the
determination of the strength of the formed intestinal anastomoses, to one degree
or another, are based on the determination of the tensile strength with an increase
in intra-intestinal pressure, however, in our opinion, the indicators of anastomosis
regeneration should be supplemented by assessing the
strength of the intestinal
anastomosis based on morphometric indicators.
Aim
Improving the results of resection surgical interventions on the
gastrointestinal tract in emergency surgery by using platelet-rich plasma and
accelerating regeneration processes in the anastomosis zone.
