This study aimed to identify preoperative risk factors for AL using a five-year dataset from two Romanian surgical clinics. Materials and Methods: A retrospective cohort of 155 patients undergoing colorectal resection with primary anastomosis (105 from \u201cColentina\u201d Hospital and 50 from \u201cDr. I. Cantacuzino\u201d Hospital) was analyzed. Preoperative demographic, clinical, and laboratory data were extracted and assessed using univariate and multivariable logistic regression. Statistical analyses were performed using IBM SPSS. Results: The overall AL rate was 10.3%. Multivariable analysis identified high ASA class (OR 17.6; p = 0.001), emergency surgery (OR 32.2; p = 0.0007), and heavy alcohol use (OR 15.3; p = 0.004) as independent predictors of leakage. While low preoperative albumin and smoking were associated with leakage in a bivariate analysis, these did not remain significant after adjustment. Notably, all laboratory markers were based on preoperative values, distinguishing our approach from prior studies that commonly evaluated postoperative biomarkers. No statistically significant effect was found for neoadjuvant chemotherapy or radiotherapy after controlling for other covariates. Conclusions: High ASA score, alcohol abuse, and emergency surgery were the strongest independent predictors of AL in our cohort. The lack of predictive power of certain widely reported factors, such as low albumin, may reflect our dataset\u2019s focus on preoperative optimization. These findings support the use of individualized risk assessment and reinforce the role of preoperative preparation in reducing leak incidence in colorectal surgery.<\/jats:p>","DOI":"10.3390\/diagnostics16060837","type":"journal-article","created":{"date-parts":[[2026,3,11]],"date-time":"2026-03-11T16:41:47Z","timestamp":1773247307000},"page":"837","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Understanding Anastomotic Healing in Colo-Rectal Surgery; a Multicentric 5-Year Analysis of Predictive Factors for Integrity and Fistula Formation"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-9600-6229","authenticated-orcid":false,"given":"Dumitru-Dragos","family":"Chitca","sequence":"first","affiliation":[{"name":"General Surgery Department, Carol Davila University of Medicine and Pharmacy, 050474 Bucharest, Romania"},{"name":"General Surgery Clinic, \u201cColentina\u201d Clinical Hospital, 020125 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-1887-0388","authenticated-orcid":false,"given":"Octavian","family":"Mihalache","sequence":"additional","affiliation":[{"name":"General Surgery Department, Carol Davila University of Medicine and Pharmacy, 050474 Bucharest, Romania"},{"name":"Surgical Department I, \u201cDr. I.
