CONCLUSION
The present systematic review is of great interest in clinical and
surgical medical practice because it presents the development of acute
abdomen after vaccination against COVID-19. However, few studies related
to this association have been reported, so they are infrequent and occur
in the minority of vaccinated individuals. Despite this, patients
responded adequately to treatment and no deaths related to these
complications were reported. Importantly, the study involved a small
sample of patients, and future observational studies are required. These
studies could elucidate the various pathophysiological mechanisms by
which this association occurs and provide more robust information on the
safety of SARS-CoV-2 vaccines. Ultimately, the cases included and
studied in this review indicate that cases are minimal upon
administration of vaccination, so vaccines generally do not develop
acute abdomen. However, despite this, physicians should monitor patients
with a history or risk factors and observe the evolution of patients
through clinical follow-up with a possible risk of developing these
complications after any type of vaccination against COVID-19.
