Needle-knife papillotomy: a safe and effective technique in experienced hands.

BACKGROUND/AIMS: Results from studies evaluating needle-knife papillotomy are conflicting. The aim of this retrospective study was to assess the safety and efficacy of needle-knife papillotomy as a precut procedure to achieve biliary access during ERCP. METHODOLOGY: During a period of seven years, ERCP was performed 938 times. During this time, needle-knife papillotomy was carried out in 68 patients, with complete follow-up obtained in all patients. The follow-up concentrated on the safety and efficacy of the procedure and short-term complications. RESULTS: Cannulation of the common bile duct was successful immediately after needle-knife papillotomy in 44 patients (66%), during a second ERCP in 18 patients (26%), and in a third ERCP in 2 patients (3%) achieving a total cannulation rate of 94%. There were no needle-knife papillotomy related deaths. Complications included bleeding in 5 patients (7%), and pancreatitis in 3 patients (4%). All complications were managed conservatively. CONCLUSIONS: Our experience indicates that needle-knife papillotomy is a versatile, effective and safe technique of gaining biliary access in patients in whom deep cannulation proves impossible and biliary access is considered essential.

Lipohyperplasia of the ileocecal valve as a cause of intussusception.

We present a case of lipohyperplasia of the ileocecal valve causing episodes of intussusception, and visualized by abdominal ultrasound and CT as a "target-like" appearance. At surgery, a large yellow soft mass was in the region of the ileocecal valve, raising the suspicion of lipohyperplasia. Resection of the fatty tissue from the ileocecal valve was performed at operation, after histologic diagnosis on frozen section. Our case suggests that limited resection removing the terminal ileum is effective and preferable to more extensive resection.

Recurrent colonic Dieulafoy's lesion associated with bizarre vascular malformations and abnormal von Willebrand factor.

Colonic Dieulafoy's lesion is an unusual source of massive lower gastrointestinal haemorrhage. It is characterized by severe bleeding from a minute submucosal arteriole that bleeds through a punctuate erosion in an otherwise normal mucosa. We describe an elderly man who presented recurrent rectal bleeding from a Dieulafoy's lesion in the sigmoid colon associated with bizarre colonic vascular malformations and an abnormal von Willebrand Factor. He was successfully treated by endoclips application. The clinicopathologic features of this unusual association are discussed and suggestions are made for diagnosis and management.
