Introduction: Intestinal anastomosis is a procedure commonly used in elective and emergency surgery, the technique for its performance is subject to various factors such as: place of anastomosis, probability of anastomosis leakage, anastomose loop diameter and patient comorbidities [1]. AD represents an indicator of the quality of the surgery performed and has been the subject of multiple studies on the factors associated with said complication, especially in colorectal anastomosis.3 Since there have been very few studies carried out in our country on this subject, we decided to carry out this border study.

Objectives: To identify risk factors associated with anastomosis dehiscence in the case series.

Materials and methods: An experimental retrospective analytical study was performed on 52 patients, who underwent intestinal anastomosis, those who presented with anastomosis dehiscence and those who did not present anastomosis dehiscence, regardless of whether the procedure was urgent or was elective over 18 years, in the period from January 2016 to December 2021.

Results: 52 patients were evaluated, 16 (31%) women and 36 (69% men), of which a total of 8 people (15%) had anastomosis dehiscence, 25 (48%) were emergency surgeries, 6 (11%) had sepsis criteria (p<0.01), 6 (75%) had comorbidities (p<0.01). The ileum was the segment that presented mostly anastomosis dehiscence.

Conclusion: Our study shows that sepsis and the presence of comorbidities are the factors most associated with anastomosis dehiscence.
