Primary leiomyoma of the liver.

This case report describes a primary hepatic leiomyoma presenting as a mass lesion detected on ultrasonography of the abdomen in an asymptomatic hepatitis B carrier on routine surveillance. Primary leiomyomata of the liver are rare occurrences, with only 9 cases reported in the literature. The presenting features of primary hepatic leiomyomata and diagnostic approach towards such lesions are discussed. The significance of such tumours in the immunocompromised is also mentioned.

Guideline on training and credentialing in endoscopic retrograde cholangiopancreatography.

The aim of the Endoscopic Retrograde Cholangiopancreatography (ERCP) Working Group was to examine the issues of training, credentialing and quality control in ERCP in Singapore. Published guidelines and clinical trials concerning issues of training, complications and quality control in ERCP have been reviewed. The Working Group recommended that a trainee reach a minimum threshold of 200 cases before the assessment of competency. The target for achievement of competency was set at an 85 percent successful cannulation rate for native papilla. To perform advanced ERCP, endoscopists should have undergone dedicated training either in a recognised training centre or in conjunction with and under the guidance of a more experienced colleague, until technical competency is achieved. Precut should only be performed by endoscopists with experience and expertise in performing Levels II and III ERCP, who have been formally proctored. An audit of ERCP should examine parameters such as appropriate indication, success rates of selective cannulation, technical success rate of commonly performed procedures and procedure-related complications. To maintain technical competency, an individual should be performing ERCP on a regular basis. In conclusion, the innate risks of ERCP necessitate that all ERCP practitioners should be appropriately trained, practise within their expertise level and maintain regular practice in order to minimise risks and improve patient outcome.

Is there a place for N.O.T.E.S. in the diagnosis and treatment of neoplastic lesions of the pancreas?

Natural orifice transluminal endoscopic surgery (NOTES) is the latest minimally invasive technique in the surgical armamentarium. Indeed it is stoking controversy already among both practitioners and patients, challenging established surgical, ethical and even moral principles. One organ which has been at the forefront of minimally invasive intervention is the pancreas. This review looks at the basis for evolving NOTES capabilities in the diagnosis and treatment of pancreatic diseases, with particular reference to neoplastic lesions and their complications. A summary of recent advancements in gastro-intestinal endoscopy and laparoscopic surgery as applied to the pancreas is presented. The possible role and feasibility of NOTES are outlined against this background.
