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. The other patient developed a recurrent subphrenic abscess 10 months after the initial operation, which eventually was shown to be caused by a lost gallstone. Although these are rare complications of laparoscopic cholecystectomy, they should be recognized as potential causes of recurrent abdominal pain, even months after the procedure.
