In july of 2013, i had a partial nissen. my hiatal hernia recurred on 04/14/14. had an open surg. on 07/17/14, hernia is back. should i try again?

May not be true : When you say the hernia is back, it is difficult to know in what capacity. Barium swallow frequently shows a "hernia", but the test has limitations, and it is usually small and not clinically significant. Typically, anti reflux procedures are primarily done to relieve heartburn and regurgitation. If the symptoms are better, no need to repeat an operation. Also may want to consider Stretta If the reflux symptoms are back.

Not sure: there is a very high recurrence rate for hiatal hernia repairs. If you have already had once recurrence, I would be very careful looking at further surgery. Most recurrences don't cause symptoms and don't require repair. If you need surgery because of symptoms, you should only go to an expert who is experienced with re-operative esophageal surgery.

Depends: How symptomatic? Other issues? Weight, general health? See your surgeon, and probably a second opinion.
