Right colonic diverticulitis: US and CT findings--new insights about frequency and natural history.

Purpose: To evaluate how the use of ultrasonography (US) and computed tomography (CT) has changed insights on the frequency and natural history of right colonic diverticulitis.

Materials And Methods: Clinical findings, US and CT images, and clinical and surgical records in 44 patients with a final diagnosis of right colonic diverticulitis seen over 11 years were retrospectively studied.

Results: Of the 44 patients, three underwent diverticulectomy, and 41 were successfully treated conservatively.

False aneurysm of a hepatic artery branch and a recurrent subphrenic abscess: two unusual complications after laparoscopic cholecystectomy.

Although laparoscopic cholecystectomy has become a safe and effective alternative for open cholecystectomy as treatment of symptomatic cholelithiasis, it may be followed by different complications. Two cases are presented with unusual complications after laparoscopic cholecystectomy. One patient was readmitted 11 days after laparoscopic cholecystectomy with severe upper abdominal pain and a false aneurysm of a branch of the right hepatic artery.

A review of the literature suggests that neurofibromatosis patients are at significant risk for developing a periampullary tumour which is nearly always of neuroectodermal origin.
