1.Laparoscopic Nephrectomy: Experience with 23 Cases.
Korean Journal of Urology 2001;42(2):206-212
PURPOSE: Laparoscopic nephrectomy has become accepted as a method of simple nephrectomy replacing with open nephrectomy in patients in whom a kidney requires removal for benign disease. Laparoscopic nephrecto my is widely performed and extends its indications. We evaluated our experience with the laparoscopic nephrectomy to assess the clinical efficacy. MATERIALS AND METHODS: Between April 1996 and September 1999, 23 patients (7 men and 16 women, mean age 44.1 years old) underwent laparoscopic nephrectomy, 16 by women, mean age 44.1 years old) underwent laparoscopic nephrectomy, 16 by the transperitoneal approach and 7 by the retroperitoneal approach. Operative and clinical records were reviewed. The underlying pathological conditions included 20 cases of non-functioning kidney, 2 cases of hypoplastic kidney with complete duplication and ectopic ureter, and 1 case of ureter tumor. Four ports (21 cases, two 12mm ports and two 5mm ports) or 5 posts ( 2 cases, two 12mm ports and three 5mm ports) were used. RESULTS: The laparoscopic procedure were successful in 20 cases (87%). Three patients had open conversion due to unclear anatomy, severe adhesion, and adrenal bleeding. In successful cases, mean operative time was 253+/-83 minutes (range 140-545), mean hospital stay was postoperative 5.2 days. Intraoperative and perioperative complications were noted in 6 patients, including bleeding requiring transfusion in 3, wound infection in 1, severe subcutaneous emphysema in 1, diarrhea in 1. CONCLUSIONS: Laparoscopic simple nephrectomy is feasible, effective, and safe treatment option. It is a less invasive alternative to open surgery providing a more rapid recuperation and superior cosmetic effect.

A case of established infected nonunion of femur after open reduction and internal fixation of proximal femoral fracture with plate and screws in a 20-year-old man has been satisfactorily treated with a conventional Kiintscher nail filled with antibiotic laden bone cement in its hollow cavity. Though the removal of plate and screws, wound debridement, insertion of antibiotic laden bone cement bead at the nonunion site with temporary external skeletal fixation and skeletal traction preceded, a rigid fixation by the nail and vancomycin elution from the cement are believed to have contributed for bony union without troublesome complication of infection in this case.

Lumbar spinal stenosis is a common category of spinal disease in which a decrease in the volume of the spinal canal results in compression of the neural elements. Its pressure symptoms are characterized by vague back-pain and chronic sciatica. The goals of surgical treatment in lumbar spinal stenosis are the relief of pain and the preservation or restoration of neurologic function. Extensive laminectomy in lumbar spinal stenosis results in postoperative instability and postoperative vertebral subluxation with pain, restricted movement, and further neural compression occurs after decompressive laminectomy. Therefore internal fixation devices have been used in these circumstances to prevent postoperative instability while the fusion being consolidated. From February 1988 to October 1988, 36 patients of lumbar spinal stenosis had undergone operations with decompressive laminectomy and segmental spinal instrumentation with transpedicular screws at the department of Orthopaedic Surgery, Yonsei University College of Medicine. In 18 patients degenerative changes in lumbar spine were the principal aetiologic factor:7 patients had spondylolisthetic spinal stenosis:ll patients had combined spinal stenosis. All patients were followed up for periods varying between twelve and ninteen months. According to Kim's criteria, the postoperative results were as follows;excellent in 17 cases(47.2% ), good in 15 cases(41.7% ) and fair in 4 cases(11.1% ). The study revealed that segmental spinal instrumentation with transpedicular screws provided a rigid fixation, early ambulation, minimal fusion and reducing of recovery period were possible. In conclusion, segmental spinal instrumentation with transpedicular screws is a good and reliable method of stabilization after extensive decompressive laminectomy.

PURPOSE: To describe the magnetic resonance (MR) findings of pigmented villonodular synovitis(PVNS) of the knee, and to evaluate the clinical value of MR in the diagnosis of PVNS. MATERIALS AND METHODS:MR imagings of seven patients with PVNS were studied. The type of lesion, presence of bony erosion, the signal intensity, and the relationship between contrast enhancement and signal intensity on T2-weighted images were analyzed, retrospectively. RESULTS: The lesion was mainly villous in three patients and nodular in four, and bony erosion was seen in one patient. On T2-weighted image, the signal intensity of the villous form was mixed iso- and hypointense in two, hypointense in one, and that of the nodular form was heterogeneous with hypo-, iso-, and hyperintensities. The hypointense portion on T2-weighted image showed poor contrast enhancement, which may suggest hemosiderin deposition or advanced fibrosis. The iso- or hyperintense portion on T2-weighted image showed strong enhancement, which suggest active cellular proliferation. CONCLUSION:MR imaging could be a very useful modality in the diagnosis as well as prediction of histological findings of the PVNS.

The objective of this paper is to introduce the schematic protocol of radiofrequency (RF) ablation for the treatment of varicose veins. Indication: anatomic or pathophysiologic indication includes venous diameter within 2-20 mm, reflux time > or =0.5 seconds and distance from the skin > or =5 mm or subfascial location. Access: it is recommended to access at or above the knee joint for great saphenous vein and above the mid-calf for small saphenous vein. Catheter placement: the catheter tip should be placed 2.0 cm inferior to the saphenofemoral or saphenopopliteal junction. Endovenous heat-induced thrombosis > or =class III should be treated with low-molecular weight heparin. Tumescent solution: the composition of solution can be variable (e.g., 2% lidocaine 20 mL+500 mL normal saline+bicarbonate 2.5 mL with/without epinephrine). Infiltration can be done from each direction. Ablation: two cycles' ablation for the first proximal segment of saphenous vein and the segment with the incompetent perforators is recommended. The other segments should be ablated one time. During RF energy delivery, it is recommended to apply external compression. Concomitant procedure: It is recommended to do simultaneously ambulatory phlebectomy. For sclerotherapy, it is recommended to defer at least 2 weeks. Post-procedural management: post-procedural ambulation is encouraged to reduce the thrombotic complications. Compression stocking should be applied for at least 7 days. Minor daily activity is not limited, but strenuous activities should be avoided for 2 weeks. It is suggested to take showers after 24 hours and tub baths, swimming, or soaking in water after 2 weeks.

To evaluate the degree of competitive exclusion against Salmonella gallinarum(S. gallinarum) of Salmonella enteritidis(S. enteritidis) infected chickens, fifty-six, 4-week old Hyline layer suspected of S. enteritidis infection were challenged with S. gallinarum. All chickens were tested for S. enteritidis isolation using cloacal swabs and serum plate agglutination test using S. enteritidis Ag. before challenge and classified into four groups(SE isolated, SE nonisolated, SE seropositive and SE seronegative). None of the SE isolated and the SE seropositive groups died after challenge and the average weight gains were 245.5g and 254.6g, respectively. But in the SE nonisolated and the SE seronegative groups, mortality was 18.2% and 20.6% and the average weight gains were 150.1g and 111.2g. The incidence of reisolation of S. gallinarum of the SE isolated and the SE seropositive groups were 41.7% and 47.6% from liver, 33.3% and 47.6% from spleen and 8.3% and 14.3% from cecum, respectively, and the SE nonisolated and the SE seronegative group were 63.6% and 64.7% from liver, 84.1% and 88.2% from spleen and 47.7% and 52.9% from cecum. The serological response of the SE isolated and the SE seropositive groups hardly changed from 75.0 and 81.8% before challenge to 75.0 and 85.7% after. But, the other two groups were found to be significantly higher after challenge and increased from 0 and 18.2% to 100%. Consequently, S. enteritidis preinfected chickens were found to be significant different in terms of mortality, weight gain, reisolation of S. gallinarum and serological response compared to noninfected chickens. Moreover, our study shows that S. enteritidis infected chickens appear strong competitive exclusion against the colonization of S. gallinarum.

We report an autopsy case of secondary hemochromatosis associated with multiple frequent blood transfusion for the treatment of aplastic anemia. A 23-year-old man had been diagnosed as having aplastic anemia at the age of 13. He received a whole blood transfusion, about 1280 ml, every month during the past 10 years. Recently he developed diabetes mellitus and a congestive heart failure. The autopsy revealed that multiple organs were affected by secondary hemochromatosis, including the liver, heart, pancreas, spleen, bone marrow, stomach, thyroid gland, adrenal glands, and testes. The lungs and liver showed gross and microscopic findings consistent with a congestive heart failure in addition to hemochromatosis. The details are presented. This is a case of rare secondary hemochromatosis occurring in a young man and presenting the classic histopathologic changes indistinguishable from those of primary hemochromatosis.
