ALAMO, J. M. et al. Role of malnutrition in intestinal anastomosis collagenization: an analysis of procollagen (PINP) and carboxyterminal telopeptide (ICTP) by radioimmunoassay. Rev. esp. enferm. dig. [online]. 2007, vol.99, n.2, pp.76-83. ISSN 1130-0108.

Introduction: some clinical, anatomo-pathological, and technical factors influence the correct healing of intestinal suture following an intestinal resection. One of the most influential factors is patient nutritional status. Objectives: to evaluate the influence of malnutrition on the viability of primary intestinal anastomosis by the analysis of collagen I deposition. Methods: 40 Wistar rats, radioimmunoassay material. We used 2 groups of rats, 20 animals in each group: a control group (A) and a "malnutrition" group (B). Results: there was a decrease in PINP (procollagen) deposition in the colon of group B rats as compared to the colon of group A (0.3620 and 0.4340 µg/g respectively) (p = 0.032). There is an increase in ICTP (carboxyterminal telopeptide) in the colon of group B (0.9545 as against 0.8460 µg/g in group A) (p = 0.875). In anastomoses of group B there was a decrease in PINP synthesis as compared to group A (0.376 and 0.468 µg/g respectively, p = 0.002). As regards ICTP, there was an increase in group B (p = 0.330). In relation to the control group no differences were observed in ICTP increases in group B (p = 1). Conclusions: colonic anastomosis increases the levels of PINP and ICTP in healed tissue (p = 0.000); malnutrition reduces collagenization in anastomoses (p = 0.000).
