his technique was performed on 50 patients with congenital dilatation of the bile duct including 35 females and 15 males, ranging in age from 3 months to 33 years old. Patients treated from 4/1996 to 6/1999 at the Pediatric Institute and at the Bach mai Hospital, with abdominal pain in 76%, jaundice in 58%, classic triad in 12%. The diagnosis and the indications for operation have based on the ultrasonography.The cyst flattened by bile suction and the intraoperative cholangiography was very useful for the dissection, the resection of cysts and the performance of the anastomosis. There were not particular difficulties to prepare a jejunal segment about 25 cm in length, 40-50 cm from Treitz, passing through a hole made in the transverse mesocolon and duodenum. 35 intussusception valves were made in the isolated loop of jejunum. There was no mortality. Only 1 case with infected wound and another case with the left underdiaphragmatic abscess caused by the leakage of the jejuno-jejunal anastomosis, successfully treated by the drainage of the abscess. All the patients normally discharged from the hospital

Objectives: To evaluate and compare ectasia and pseudoectasia in post-myopic LASIK patients presenting with corneal topographic changes indicative of ectasia using the Ectasia Risk Factor Score System (ERFSS). Methods: Single-center retrospective comparative case series of a consecutive chart review of cases in 18 years who underwent bilateral myopic-LASIK and showed topographic changes indicative of ectasia. Results: Four patients were included. Group 1: pseudoectasia eyes, consisting of two patients with bilateral pseudoectasia, and Group 2: ectasia eyes, consisting of two patients with unilateral ectasia. The clinical course of the cases was discussed and compared based on the ERFSS parameters: topography pattern, residual stromal bed thickness, age, preop thinnest cornea, and pre-operative spherical equivalent (SE) manifest refraction (MR). Group 1 scored zero to low risk for developing ectasia while Group 2-eyes with ectasia scored moderate risk. The predictive value of the ERFSS was 1 in this study. Conclusion The ERFSS is a good measure in deciding the suited treatment plan for patient undergoing refractive procedure. Knowing the clinical course of ectasia and pseudoectasia is helpful in the therapeutic approach since pseudoectasia is reversible when identified and managed early as seen in this study.

Fairly specific and important duodenoscopic findings for diagnosing mucinous ductal ectasia (MDE) of pancreas include a prominant ampulla, patulous ampullary orifice and extrusion of mucin through the ampulla. However, we have experienced two cases of mucinous ductal ectasia without these pathognomonic appearance of ampulla. Initially, two cases were admitted for evaluation of pancreatic multicystic lesions, and MDE was incidentally found. Their pancreatographic findings showed normal main duct and cystic dilatation confined to the branch ducts. On gross findings of surgical specimens, a duct dilatation with gelatinous mucin was localized at the uncinate process of the pancreas. Microscopically, the ductal epithelia containing mucin were lined with well-differentiated tall columnar cells showing focal hyperplastic change. We report these unusual cases of MDE with review of the literatures.

Sporadic non-ampullary duodenal adenoma is uncommon and found incidentally during endoscopic examinations. Brunner's gland hyperplasia is commonly encountered during endoscopic examinations. Adenomas arising from Brunner's gland hyperplasia originate from the glandular cells, and the surface epithelia are usually intact. Little has been reported on adenomas originating from the surface epithelium that overrides Brunner's gland hyperplasia. Here, we report a case of a sporadic non-ampullary duodenal adenoma overriding the cystic dilatation of Brunner's gland hyperplasia.

Wirsungocele is defined as a cystic dilatation of the terminal portion of the main pancreatic duct, and this is an extremely rare malady. The pathophysiology of Wirsungocele has been proposed that a congenital or acquired weakness in the distal duct that's associated with functional obstruction may lead to the formation of Wirsungocele. In addition, mechanical obstruction of the distal duct has been considered as another mechanism of Wirsungocele. We report here on the imaging findings of two cases of Wirsungocele that seemed to occur by different pathophysiologic mechanisms.
