Preparing for a reversal

Hello my husband is 4 months post emergency surgery for complicated diverticulitis which resulted in an end colostomy. He had no complications from first surgery and all the testing indicated everything is healing ,met with surgeon and he is scheduled for reversal in 60 days. Is there anyone who has been through this type of reversal who hopefully has had good results. Any tips to prepare beforehand or what to expect after would be helpful . Thank you
