Malignant transformation of urachal adenoma is exceedingly rare, with intestinal metaplasia as the most common contributing mechanism. It is recommended that a urachal adenoma be regarded as a pre-malignant condition and be subject to endoscopic surveillance. A local en block excision of the tumor mass with urachalectomy and umbilectomy results in possible long-term survival. The median survival after platinum-based chemotherapy is limited for patients with extravesical disease. Here we report a case of synchronous urothelial carcinoma of the bladder and urachal adenoma that transformed into adenocarcinoma.

Fecaliths or fecomucoliths can form in rectal stumps after a Hartmann procedure or in a coloneovaginal conduit. They can cause significant distress to the patient by causing symptoms such as discharge and odor. We describe a novel and effective method of endoscopic obliteration and removal where other techniques such as removal during examination under anesthesia or serial enemas have failed. By using a combination of hydrodissection with a saline injector gun and biopsy forceps and a polypectomy snare to break down the fecomucolith or fecalith, this troublesome problem can be resolved endoscopically. Successful removal of the fecalith/fecomucolith and resolution of the symptoms for the patients were achieved. No complications are reported. We describe an effective and novel method for endoscopic removal of fecaliths and fecomucoliths.
