Proper management of childhood and adolescent varicocele remains still controversial. In general, all methods for varicocele ablation for adults are available and include open surgical ligation, laparoscopic ligation, or percutaneous ablation. We evaluated the usefulness of percutaneous embolization of internal spermatic vein in boys with varicocele. Between February 1988 to May 1996, 48 boys of 53 varicoceles underwent percut aneous embolization. In 49 cases, the embolization were technically possible and in the other 4 cases, we could not access the internal spermatic vein because of vasospasm and venous abnormality. The results were successful in 40 cases (81.6%) and failed in 9 cases (18.4%), including 4 (8.2%) of persistent and 5 (10.2%) of recurred cases. There were no major complications except 3 cases of extravasation of contrast material. Percutaneous embolization may be recommended as a primary treatment for childhood and adolescent varicocele.

Background/Aims: Periampuilary diverticulum has been known to be associated with various bilio-pancreatic diseases such as choledocholithiasis and disturbs performing selective cannuiation of ERCP and EST. This present study aims to investigate anatomical morphology of periampullary diverticulum and to determine whether periampullary diverticulurn influences difficulty and complication performing of ERCP and to analyse the relationship between periampullary diverticulum and choledocholithiasis. Methods: We reviewed records of chart and diverticular pictures in 1389 cases of underwent ERCP and evaluated the incidence, size, direction, location of periampullary diverticulum and its influence against performing of ERCP and investigated its relationship with bilio-pancreatic diseases such as choledocholithiasis.(continue..)

PURPOSE: Most recently developed anti-adhesive membranes are not suitable for laparoscopic surgery due to weak mechanical properties or adhesive characteristics. To overcome these problems, we prepared electrospun bioabsorbable nanofibrous poly (lactic-co-glycolic acid)-based membranes as an adhesion barrier. We evaluated the efficacy and safety of this material for laparoscopic surgery in a rabbit model. METHODS: A standardized laparoscopic surgical trauma was made on the rabbit's uterine horn and adjacent abdominal wall to induce adhesion formation. The injured uterus was covered by a nanofibrous barrier or it was left untreated (the negative control group) (each group: n=14). To evaluate acute toxicity of this material, blood sampling was made 3 and 7 days after laparoscopic surgery to check liver and renal function. Three weeks after laparoscopy, a second look laparoscopy was performed and the adhesions were scored according to Blauer's scoring system. Tissue between abdominal wall and uterus was obtained to examine microscopically. Liver, kidney and uterus were harvested to examine chronic toxicity. RESULTS: 36.4% of the nanofiber treatment group and 70% of the untreated control group showed severe adhesions (grade>3) after laparoscopic surgery but failed to get a statistical significance (P=0.198). Acute and chronic toxicity induced by this material were not noted in the blood and tissue exam. CONCLUSION: This study showed that nanofiber barrier seems to be a novel resorbable biomaterial for the reduction of postoperative adhesions. Easy placement and handling of this material make these membranes potentially successful candidates for laparoscopic surgery. But further study is needed to get a statistical significance.

A retrospective review of 36 patients with infective endocarditis by strict case definition was performed from 1972 through April of 1984. Male to female ratio was 1:1.25, with mean age of 19.1. Thirty of the 36 patients(83.3%) had the history of predisposing heart diseases: congenital heart disease was most frequent one below the age of 20, rheumatic heart disease between the age of 20-39 and degenerative heart disease above the age of 40. The commonest presenting symptoms were fever, dyspnea, and malaise, and the commonest signs were fever, murmur, and hepatomegaly. Average hemoglobinand hematocrit were 10.1g/dl and 30.8% respectively, showing moderate degree of anemia. White cell count was 11,600+/-5400/mm3 and erythrocyte sedimentation rate was 46+/-18mm/hr. Over four fifths of the patients demonstrated proteinuria and elevated C-reactive protein. Two thirds of the patients showed microscopic hematuria and one third showed positive rheumatoid factor. Eight patients(22.2%) showed arrhythmia and 4(11.1%) showed conduction abnormalities on electrocardiography. The commonest etiologic microorganisms were alpha-hemolytic streptococcus(30.6%) and staphylococcus aureus(22.2%). Abacteremic cases were found in 38.9% of the patients. To compared with alpha-hemolytic streptoccus endocarditis the cases caused by staphylococcus aureus showed the shorter duration of symptoms before admission, the less frequent complication, the higher fever, and the more elevated white cell counts. To penicillin, alpha-hemolytic streptococcus was sensitive in most cultures and staphylococcus arueus was resistant in half of them, and to aminoglycosides vice versa. To cefazolin, both microorganisms were sensitive in most cultures. In 18 of 24(75%) patients vegetation was visualized by echocardiography. The most frequent site of involvement was the mitral valve. And in vegetation detected group complication rate by embolism was found to be higher. The common complications were congestive heart gailure in 24(66.75%), embolism in 8(22.2%), and metastatic infection in 6(16.7%). The mortality rate of infective endocarditis was 25%, and the causes of death were cerebral embolism in 3(8.3%), septic septic shock in 3(8.3%), congestive heart failure in 2(5.6%), and mycotic aneurysmal rupture in 1(2.8%). Conclusively in infective endocarditis the author observed the increasing prevalence of degenerative heart disease as a prdisposing heart disease and increasing incidence of staphylococcus aureus as a causative microorganism. Adn the differences of clinical characteristics between staphylococcus ureus and alpha-hemolytic streptococcus endocarditis would be helpful in diagnosis and treatment of infective endocarditis as well as recognition of prognosis.

OBJECTIVES: Developments in endoscopic technique and equipments have improved duct clearance rate in patients with extrahepatic bile duct(EHBD) stone. In this study, we reviewed our experience in extracting EHBD stones with standard and more advanced technique and equipments such as mechanical lithotripsy and extra corporeal shock wave lithotripsy. Aims of this study were to determine the overall success rate of endoscopic ex tracting for EHBD stone, to identify risk factors for failed duct clearance at initial and final therapeutic ERCP. METHODS: We retrospectively reviewed 214 consec utive patients who underwent Endoscopic Retrograde Cholangiopancreatography(ERCP) for EHBD stone over 45 months period. Factors evaluated for failed duct clearance included stone size, stone number, stone shape, concomitant stone of gallbladder and intrahepatic duct, presence of distal bile duct stricture, periampullary diverticula(PAD), Billroth-II gastrojejunostomy, and sepsis at admission. RESULTS: The overall success rate of endoscopic treatment for EHBD stone was 93.5% (200/214). The causes of failed duct clearance were failed endoscopic sphincterotomy in 5/214 (2.3%), technical failure of extracting stone in 5/214(2.3%), and aggravation of acute cholecystitis between therapeutic endoscopic sessions in 4/214(1.9%). Risk factors for failed duct clearance with endoscopic extraction of EHBD stone were size and shape of the stone, concomitant stone of gallbladder and intra hepatic duct, and stricture of distal common bile duct. The duct clearance rate with initial therapeutic ERCP was 56.5%(121/200). Risk factors for failed duct clearance with initial therapeutic ERCP were size, shape and number of stone, and sepsis at admission. The com plications of endoscopic treatment for EHBD stone were major bleeding in 5/200 (2.5%), pancreatitis in 18/200 (9.0%), but there was no perforation. CONCLUSION: Eventhough risk for failure of endo scopic treatment for EHBD stone were giant or piston shaped stone, concomitant stone of gallbladder and intra hepatic duct, and stricture of distal common bile duct, we conclude that endoscopic treatment for EHBD stone is safe and effective treatment modality, and choice of treatment.
