 After discharge, all patients will continue to drain their IPC on a daily basis for 7 days. Following this, all patients will continue to drain their IPC on an every-other-day basis until total IPC output is less than 50ml per session over 3 consecutive sessions. At which point they will be asked to undergo a clamp trial of no drainage for 7 days followed by a reattempt at drainage. Patients without return of symptoms over those 7 days and minimal drainage afterwards 50ml will be seen in the office for possible IPC removal. Patients with return of symptoms during those 7 days or more than minimal drainage afterwards 50mL will be asked to continue drainage until total IPC output is again less than 50mL per session over 3 sessions.
