PURPOSE: The colonoscopic polypectomy has become a valuable procedure for removing precursors of colorectal cancer, but some complications can be occurred. The most common complication after colonoscopic polypectomy is bleeding, which is reported to range from 1% to 6% and which can be immediate or delayed. Because the management of delayed postpolypectomy bleeding could be difficult, the use of preventive technique and reductions of risk factors are essential. METHODS: From January 2007 to December 2008, delayed hemorrhage occurred in 18 of the 1,841 polypectomy patients examined by one endoscopist. These cases were reviewed retrospectively for risk factors, pathologic findings, and treatment methods. RESULTS: Delayed bleeding occurred in 18/1,841 patients (0.95%). The mean age was 55.9 +/- 10.9 years, and the male-to-female ratio was 8:1. The most common site was the right colon (11 cases, 61.1%), and the average polyp size was 9.2 +/- 2.8 mm. Delayed bleeding was identified from 1 to 5 days after resection (mean, 1.6 +/- 1.2 days). The most common macroscopic type of polyp was a sessile polyp (10 cases, 55.6%), and histologic finding was a tubular adenoma in 13 cases (72.2%). Seventeen cases were treated with clipping for hemostasis and 1 case with epinephrine injection. CONCLUSION: The right colon and a sessile polyp were associated with an increase in delayed postpolypectomy bleeding. Reducing risk factors and close observation were essential in high risk patients, and prompt management with hemoclips was effective.

PURPOSE: The anal verge is the border of the lowest part of the anal canal. However, grossly, it may be difficult to identify. Therefore, to assess the precise position of the anal verge, we performed this study. METHODS: From August 1 to 31, 2006, 40 patients having anal surgery under spinal anesthesia were selected randomly. Prior to surgery, the anal verge was marked with the patient in the Sims's position. After marking, the anus was pulled bilaterally to both sides using bandages, and the lengths of the four areas were measured with the patient in the jackknife position. RESULTS: With the patient in the jackknife position, the anal verge was moved laterally by an average of 1.09+/-0.36 cm. The shift distance of the anal verge relative to the anal area was measured; the shift distance in the posterior direction was 1.1+/-0.30 cm, that in the anterior direction was 0.85+/-0.25 cm, that in the right lateral direction was 1.22+/-0.41 cm, and that in the left lateral direction was 1.20+/-0.34 cm. The shifted distance to the posterior area was significantly longer than that to the anterior area (P<0.05). CONCLUSION: When performing anal surgery with the patient in the jackknife position, the anal verge is shifted to the lateral side of the anus compared to its position when the patient is in the normal position. Notably, the shift distance to the posterior area was significantly longer than that to the anterior area. By assessing the precise position of the anal verge, the surgeon can reduce the resection range of the anoderm and create an appropriate drainage wound.

Authors reviewed 28 cases of displaced acetabular fracture treated operatively from Februay 1991 to January 1996 and followed up more than 1 year. The clinical results were retrospectively analyzed with consideration of surgical problems and complications. The results were as follows; 1. According to Letournels classification, we had 16 elementary fractures(57%) and 12 associated fractures(43%). 2. Kocher-Langenbeck approach in 16 cases, ilioinguinal in 9 cases, extended iliofemoral 2 cases and combined approach in 1 case were used. 3. The devices for internal fixation were as follows: screw only in 12 cases(elementary fracture 9cases, associated fracture 3 cases), plate and screw in 16 cases(elementary fracture 7 cases, as-sociated fracture 9 cases). 4. There were complications such as 3 degenerative arthritis, 2 superficial wound infection, 1 iatrog-enic sciatic nerve palsy and 1 avascular necrosis of femoral head and no postoperative heterotro-phic ossification. 5. Satisfactory reduction by radiologic criteria was gained in 23 cases(82%). Satisfactory results by clinical criteria(by dAubigne & Postels) was gained in 21 cases(75%). Only 2 patient with a satisfactory radiologic reduction was clinically unsatisfactory. It seems that the satisfactory operative reduction of the fracture is the factor that correlates best with a satisfact-ory clinical result.

Intrameduallary spinal hemangioblastoma is frequently associated with syringomyelia. It grows slowly and can be removed totally. Syringomyelia can be subcided by total removal of tumor and opening of syringomyelia. Two cases of intramedullary spinal hemangioblastomas associated with syringomyelia are reported. Intramedullary tumor and syrinx was easily diagnosed by magnetic resonance imaging(MRI). They are successfully managed by total removal of tumor and opening of syrinx. Patients showed improved neurological status after operations.

PURPOSE: To evaluate the damage to corneal endothelial cells following coaxial phacoemulsification and bimanual microincision cataract surgery (MICS). METHODS: We measured and compared the changes in the corneal endothelial mean cell density, cell size variation coefficient, hexagonality, and central corneal thickness in senile cataract patients who had received either coaxial phacoemulsification (Group 1, n=20), MICS using ultrasound (Group 2, n=20), and MICS using laser (Group 3, n=20). The endothelial cell parameters and corneal thickness were evaluated preoperatively and at 1 week, 1 month, and 2 months postoperatively. RESULTS: There was no significant difference among the three groups in terms of the endothelial cell parameters and corneal thickness during two months (p>0.05). CONCLUSIONS: MICS is a safe technique that does not appear to be associated with more damage to the corneal endothelium than coaxial phacoemulsification. A longer follow-up study is necessary to investigate its potential benefits for replacing conventional surgery.

Pyogenic liver abscess (PLA) can be caused by bacteria entering the liver via the portal vein or primary bacteremia, or it can be cryptogenic. Recently, Klebsiella pneumoniae has been increasingly found as a PLA pathogen. PLA due to this bacterium often leads to formation of extrahepatic abscesses. The treatment of choice is dual therapy with insertion of percutaneous catheter drainage and antibiotic therapy. We report 2 cases of PLA due to K. pneumoniae in immunocompetent children. We successfully treated patient 1 with percutaneous catheter drainage for 18 days and 6-week course of antibiotic therapy. Patient 2 was treated with percutaneous needle aspiration and antibiotic therapy for the same period. In both patients, the PLAs showed the ultrasound-confirmed resolutions after the dual therapy.
