ANATOMO-EXPERIMENTAL BASIS OF MICROSURGICAL ESOPHAGEAL-INTESTINAL ANASTOMOSIS
There are presented the results of anatomic studies of esophagus, small and large intestine on the sectional material of people cadavers. The longest empty mesentery was noted in jejunum as compared with ileum and transverse mesentery. The most correlation was revealed between the outside diameter of esophagus and small intestine. The morphometric studies of walls of the mentioned hollow organs showed the correspondence of the submucosa thickness in esophagus and small intestine and the marked prevalence of muscular layer of esophagus than that of small intestine. On the cadaveric complexes we have correlated the results of the formation of two-rowed microsurgical and two-rowed macrosurgical anastomoses of empty intestine with the ones of lower-thoracal and abdominal parts of esophagus. On the histotopograms there are pointed out the advantages of macrosurgical joints in a strong junction of mucous membrane submucoses and in the possibility of the creation of sphincter-like structure through prevalence of seromuscular case of esophagus over the small-intestinal one. In experiments in animals have shown healing of microsurgical anastomosis by first intention with the creation of sphincter-like structure.
