The purpose of this study is to assess incidence, treatment modalities and outcome of complicated and uncomplicated diverticulitis in highly immunosuppressed lung transplant recipients (LTRs) in order to establish improved treatment strategies in this high risk patient collective.

Sigmoid diverticulitis is common and potentially problematic in immunosuppressed patients. The choice between conservative and surgical treatment for uncomplicated diverticulitis remains unclear, as well as the value of the Hartmann's procedure (HP) for complicated diverticulitis.

Our aim is to assess incidence, treatment options and outcome of complicated and uncomplicated diverticulitis in highly immunosuppressed lung transplant recipients (LTRs) by retrospectively analysing our prospective database of around 400 lung transplant recipients transplanted between 1992 and 2013.

Inclusion Criteria:

• Lung transplant recipient
• Diverticulitis

Exclusion Criteria:

• none

We want to retrospectively analyse our prospective database of lung transplant recipients at our institution between 1992 and 2013 with diverticulitis episodes.
