Complicated diverticulitis in a de novo kidney transplanted patient

Diverticular disease is frequent amongst the elderly and immunosuppressed patients. It mainly presents as sigmoid diverticulitis, but severe complications, like bleedings, infections and colon perforation may occur, frequently due to immunosuppressive therapy. Moreover, antibiotherapy and hemostatics may not efficiently control evolution in such cases. Early diagnose and adequate treatment of colonic diverticulosis complicated with lower gastrointestinal bleeding and diverticulitis in immunocompromised patients. We report a 55-year-old patient who underwent de novo renal transplantation one year ago and recently developed a severe diverticular bleeding complicated by hemorrhagic shock. Colonoscopic examination revealed diverticular disease with diverticulitis and severe, diffuse bleeding, mainly in the descending colon. Due to his immunocompromised status and unfavorable evolution under hemostatics, recombinant coagulation factor Vlla (rFVlla) was given to avoid surgery. The bleeding stopped after two doses of rFVlla. Unfortunately, after three weeks, lower quadrant pain, tenderness, abdominal distention, and fever occurred, in spite of immunosuppressive drug changing and adequate conservative therapy. Abdominal computed. tomography (CT) scan revealed complicated diverticulitis, so patient underwent surgery, with partial colectomy, followed by total recovery. In conclusion, diverticulosis coli complicated with lower gastrointestinal bleeding and diverticulitis in immunocompromised patients was for us a challenging diagnosis, as well as a therapeutic issue. Treatment options, usually based on our local resources and expertise, considered conservatory therapy as the first choice, keeping surgical maneuvers just as a rescue solution.
