Uretero-ileal fistula : an unusual complication of Crohn's disease

We report a case of urteroileal fistula in a young 22 year-oldman with Crohn's disease, who presented with microscopic hematuria and severe diarrhea. Excretory urogram and retrograde pyelography showed a fistula between the right ureter and the terniinal ileum which was succesfully managed with conservative approach using a double J ureteral stent.


Endosonographic probe-guided endoscopic removal of colonic pedunculated leiomyoma

We report a rare case of endoscopic removal of colonic pedunculated leiomyoma with an aid of endoscopic ultrasonography (EUS). A 46-year-old man was admitted to our hospital with complaints of lower abdominal pain and alternating constipation and diarrhea. Colonoscopy revealed a small pedunculated polyp in the transverse colon covered with almost normal mucosa. EUS showed a hypoechoic solid tumor with clear margins and smooth contour in the second to third layer. We considered this lesion as a submucosal tumor of the colon with no continuity to the muscularis propria. We perforiined endoscopic removal of this tumor successfully, and histological diagnosis was a leiomyoma. Endoscopic removal of colonic pedunculated leiomyoma is rare. Moreover, m our case, EUS showed typical findings of colonic leiomyoma and was useful to assess the location of the submucosal tumor. We describe herein our experience and discuss similar cases reported in the English literature.


Hepatobiliary cystadenoma with mesenchymal stroma mimicking hydatid cyst. Report of a case

We report on a case of hepatobiliary cystadenoma with mesenchymal stroma in a 44-year-old Caucasian woman who presented with upper abdominal discomfort. Ultrasound (US) and computed tomography (CT) showed a cystic mass resembling hydatid cyst. Endoscopic retrograde cholangiography (ERC) demonstrated communication with the left hepatic duct. At surgery, a cystic mass with communication to the left hepatic duct was found and resected en bloc with a margin of normal liver tissue. Histological examination showed a hepatobiliary cystadenoma with mesenchymal stroma.
