No worries..
I had my spleen removed 2 yrs ago.. They said its size as a rugby ball n the incision was abt 15cm.
Anyway, it only took 2 weeks...1 day prep, 1 day surgery, 2 dys icu, and 10 dys hospital bedrest.. Just prepare a stock of good books, movies, also games in ur tablet besides upcoming laugh n reunion from families & friends
Then probably few more days at home before going back to ur routines..
