Mortality rate comparison of enterotomy and resection and anastomosis (enterectomy) in dogs with foreign-body obstructions



Open Access Logo



PICO question

In dogs with gastrointestinal foreign-body obstruction undergoing surgical correction, is the mortality rate in the perioperative period for those receiving resection and anastomosis higher, lower, or equivalent to those receiving an enterotomy?


Clinical bottom line

Category of research question


The number and type of study designs reviewed

Four retrospective studies were reviewed

Strength of evidence


Outcomes reported

It would appear that the mortality rate for resection and anastomosis for the purpose of foreign-body removal is higher than that of enterotomies performed for the same reason


There is insufficient evidence directly comparing enterotomies with resection and anastomoses in foreign-body obstructions to definitively state that the mortality rate is higher among resection and anastomosis procedures


How to apply this evidence in practice

The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
