How long hospital stay is required for a ruptured spleen?

Depends on How Bad: In the past, splenectomy was near universally recommended for ruptured spleens. Recovery from splenectomy is usually fairly rapid, a matter of 3-4 days. Today many lower grade ruptures can be monitored in hospital without removal if the surgeon feels they are stable enough. Patients may need repeated exams, blood counts and even transfusions. This may also require 3-4 days of observation.

A few days.: If the spleen is only minorly injured and there is only minimal or no bleeding a couple of days is usually enough, as long as it is the only injury. If it is a more major rupture and there has been some bleeding it may be several days. If it has to be removed it will depend on how you do postoperatively but will likely require at least 2 days after surgery and likely more than 2.
