[Age-related surgical anatomical characteristics of the large intestine in newborn infants].

Results of anatomical-surgical and roentgeno-topographical investigation of the large intestines in 291 newborns died from diseases not connected with lesions of the intestine are described. At this age the specific features of the intestine are: poor development of the haustra, taenia, appendices epyploices. The left part of the large intestine is greater than the right one, the descending colon--than the ascending one, the sigmoid colon--than the transverse colon. The caecum is situated high, the ascending and descending occupy an oblique position, they have blund low right and acute high left bends. The sigmoid colon is characterized by a high beginning at right side position. The intestine had definite individual peculiarities in its form, size and position. Its length is within the limits of 351-765 (549 +/- 8) mm. The peculiarities mentioned make the background contributing to the development of certain pathological processes in the organ and therefore, they require a special attention. Statistically significant parameters of its form, size and position can serve as initial data for performing clinical-anatomical comparative investigations with irrigograms of the children suffering from certain congenital intestinal disorders. They should be taken into account when some surgical intervention is planned.
