MATERIALS AND METHODS: Descriptive analysis research was done for children with HSCR long-segment and TCA who underwent an operation at our institutionfrom 2013 to 2020. We assessed the functional outcome and HAEC by the Krickenbeck and the HAEC scoring, respectively.

RESULTS: We ascertained 13 HSCR long-segment and six TCA. We performed the following surgical procedures: Duhamel (n=7), Martin (n=4), Kimura (n=1), transabdominal Yancey-Soave (n=3) and transanal endorectal pull-through (n=4). All long-segment patients revealed good functional outcomes, whereas two TCA children suffered soiling and failed to achieve voluntary bowel movement. HAEC was noted in three long-segment and four TCA patients. Furthermore, surgical site infection and diaper rash were noticed in 10 and two patients, respectively.

METHODS: Thirty male Wistar rats were given a 3 centimeter infra-umbilical laparotomy wound, in`flicted on their abdomen. The colonic transection was performed at 5 cm distal to caecum, with end to end anastomosis of colon segment. They were divided into two groups. Group I was fed with standard rat chow and water. Meanwhile, Group II apart from standard feed, was also given TH 1.0 g/kg every morning until day seven post operatively. Afterwards, anastomotic bursting pressures were measured and histopathological examination on the anastomosis line was performed with light microscopes. The data from two groups were analyzed by Independent paired t test for continuous variables.

RESULTS: It was found that the tensile strength of colon anastomosis (95 % CI; p = <0.001) and the histopathological study including fibroblast count (p = <0.001) and inflammatory cells (p = 0.002) showed statistically significant difference in the favor of TH-treated group. Meanwhile, neovascularization formation was not statistically significant (p = 0.807); however, the overall count in the TH group was high.
