Background:

Major abdominal surgeries may present serious postoperative complications that require early diagnosis.

Objective:

The aim of this study was to determine the usefulness of computed tomography (CT) for the early diagnosis of major abdominal surgery complications.

Material and methods:

We conducted a retrospective, observational and descriptive study using data obtained from the medical records of patients undergoing major abdominal surgery in a private hospital. Patients were divided into two groups according to the presence or absence of symptoms suggesting a postoperative complication. Patients with symptoms were classified into 3 groups: without CT, with CT with positive findings and with CT without abnormal findings.

Results:

A total of 154 patients were analyzed; mean age was 61.3 ± 12.5 years and 83 (54%) were male. Of 48 patients (31%) with symptoms suggestive of complications, 6 had very evident symptoms and were re-operated without CT, 7 had positive findings on CT and CT was negative in 14/41. All the patients had findings that supported the decision to re-operate. There were 27 cases (17.5%) with grade 3b complications of the Clavien-Dindo classification and 3 patients (2%) died.

Conclusion:

Computed tomography was useful to confirm a complication, but not to rule it out. Clinical parameters remain of utmost importance in patients with symptoms and absence of abnormal findings in post-operative CT.
