Diverticular disease of the appendix.

We have discussed a case of appendiceal diverticulitis diagnosed at laparotomy, and reviewed the histologic and clinical findings. Although infrequently encountered, appendiceal diverticulitis must be entertained in the differential diagnosis of pain in the right lower quadrant, especially in the adult patient.

A histopathological study of the appendix at autopsy and after surgical resection.

In a study of 101 autopsy appendices and over 3000 surgically resected appendices the range of histopathological features seen in each group is described. Fibrosis and faecoliths were more common in the older autopsy group than in the younger surgically resected group. The high incidence of fibrosis in the autopsy group suggests that this is an age-related change, although some may be due to previous inflammation. The low incidence of faecoliths in the surgically resected group does not support the hypothesis that they are a major cause of appendicitis.

Bladder-sparing surgery and continent urinary diversion using the appendix (Mitrofanoff procedure) for urethral cancer.

We performed bladder-sparing surgery and continent urinary diversion in two patients with urethral cancer. The first patient was a 58-year-old man with bulbomembranous urethral cancer (squamous cell carcinoma, cT2N0M0). The second patient was a 77-year-old woman with urethral cancer invading the vaginal wall (transitional cell carcinoma with squamous cell carcinoma, cT3N0M0). After bladder-sparing urethrectomy, continent urinary diversion with appendicovesicostomy (Mitrofanoff procedure) was performed in the both patients. More than 4 years after the surgery, both patients were continent, had no trouble with catheterization, and experienced no recurrence of cancer. Bladder-sparing surgery and urinary diversion based on the Mitrofanoff procedure can be considered for appropriately selected patients with urethral cancer.
