Abstract
Anastomotic leaks (AL) are critical complications following bowel anastomosis with an incidence of up to 10.5% in infants. Previous studies in animal models and adults have suggested a link between postoperative fluid overload and hypoalbuminemia with anastomotic leaks. In infants, the role of hypoalbuminemia on anastomotic integrity after small bowel anastomosis remains unclear.
Retrospective study of infants < 1 year, undergoing elective small-bowel anastomosis between 2015 and 2024 (Ethics No.-11362-_BO_K_202). Data on demographics, weight gain, serum albumin levels and use of diuretic medication during the first five postoperative days were collected. Univariate and multivariate analysis were performed to detect risk factors for ALs in infants.
13 of 219 patients (5.9%) developed ALs. Demographics were similar comparing patients with and without leaks. In univariate analysis, serum albumin levels were significantly lower (20.3 g/l vs. 26,3 g/l, p < 0.0001) in patients with AL compared to patients without AL and multivariate analysis confirmed a significant association between low serum albumin levels and AL occurrence, CONCLUSION: In infants, small bowel anastomotic leaks are associated with low postoperative serum albumin. Whether hypoalbuminemia should be regarded as an early warning sign of an undiagnosed, developing anastomotic leak or represents a causal risk factor can only be determined with further studies.
