Abstract PDF: An appendicovesical fistula is defined as an abnormal communication between the appendix and the urinary bladder, with only a few cases reported in the literature. It is very challenging to make an early diagnosis, due to the inability of conventional imaging modalities to detect this unique pathology. The symptoms are often mild, and there are not any specific signs or symptoms that might suggest this type of anomalous communication. We report a case of a 27-year-old male patient who presented difficulty for initiating urination, dysuria, and persistent urinary tract infections. An abdominal x-ray showed a large calculus inside the bladder. A cystoscopy was performed, where the tip of the appendix was seen protruding inside the bladder with a large fecalith adhered to the bladder wall. An appendectomy and partial cystectomy with primary repair were auspiciously achieved. A review of the literature is also presented.

We report a case of urinary bladder perforation during colonoscopy. A 67-year-old female, who had undergone a transabdominal hysterectomy for uterine myomas 15 years ago, visited the emergency department with complaint of abdominal pain after a screening colonoscopy. Laparoscopic examination revealed severe adhesion between the sigmoid colon and the urinary bladder. The urinary bladder wall was weakened, and several perforation sites were found. The surgery was converted to a laparotomy. After a thorough examination, we performed primary repair for the perforation sites, followed by an omentopexy.
