Esophageal duplication is the congenital developmental anomaly manifestated as cystic or tubular type. The tubular esophageal duplication found at adult is extremely rare. A patient with tubular esophageal duplication is reported. A 37 years old male developed epigastric pain aggravated at hunger state from 2 monthes before administration. Gastrofiberscopy was done, and we could found the tubular esophageal duplication at 25 cm from incisiors. Esophagogram exposed the tunnel communicated with right anterior side of normal esophagus at upper and lower part of the tubular pathway with the length of 6 cm at T4-5 level. The microscopic finding of the tubular lumen revealed normal esophageal wall structure involving the outer part of muscle layer. Surgical resection was not done for the lesion was small and no symptom due to esophageal duplication was present. And so, the authors report this case as a tubular esophageal duplication with a literature review.

Real-time ultrasound-guided fine-needle aspiration biopsy in 137 solid breast masses was performed. Sonographic findings were categorized into three group and aspirates were categorized into three cytologic groups. The cytologic result was reported benign masses (cytologic group 1) in 71 cases (52%), malignant masses (cytologic group 2 and 3) in 44 cases (32%) and insufficient specimens in 22 cases (16%). Insufficient specimens were treated as benign masses. Excisional biopsy in 44 malignant masses and 3 benigh masses according to cytologic results, clinical findings and follow up study was performed. The result was reported 41 malignant masses and 6 benign masses. Based on cytologic criteria, sensitivity for detection of malignancy was 93% and specificity was 94%. In conclusion, the high specificity provided by ultrasound-guided fine-needle aspiration biopsy could markedly reduce unnecessary surgical excisions for benign masses and it should be routinely performed, since it can give physical and emotional benefits to patients and lead to earlier and cost effective diagnosis of breast cancer.

PURPOSE: Doppler-guided hemorrhoidal artery ligation and recto-anal repair (DG-HAL & RAR) is known for low recurrence, high patient satisfaction, and less postoperative pain. The purpose of this study is to analyze the 1-year follow-up results in patients who underwent a DG-HAL & RAR and to establish the benefits of the procedure. METHODS: Among the hemorrhoid patients who were admitted to our hospital from March 2008 to May 2010 and who underwent a DG-HAL & RAR, 97 patients who were followed up for a year were investigated. Recurrence, complications, admission period, difference in preoperative and postoperative pain, operation time, and time to return to daily activities were investigated. RESULTS: The average admission period was 1.6 +/- 1.1 days. Pain at postoperative day 7 showed no significant difference from preoperative pain (P > 0.05). The operation time was 34.0 +/- 7.3 minutes on average, and return to daily activities was timed at 2.3 +/- 2.0 days postoperatively. At the one year follow-up, no serious complications were noted, and preoperative symptoms recurred only in 14 patients (14.4%). CONCLUSION: In most patients with hemorrhoids, excluding those with severe prolapsed hemorrhoids, less pain, no serious complications, and good long-term outcome can be expected from a DG-HAL & RAR.

Purpose: Compressive hip dressings have been used to decrease the amount of postoperative bleeding after total hiparthroplasty. However, there is no data showing that a compressive dressing is effective. This study evaluated the effect of compressive dressings on the level of postoperative bleeding after total replacement arthroplasty. Materials and Methods: This prospective randomized clinical trail included 80 consecutive primary total hip arthroplasties in 72 patients. The 80 hips were randomly assigned to a compressive dressing group or a non-compressive dressing group using a table of random numbers. Forty-two hips in 37 patients were treated using the compressive dressing and the remaining 38 hips in 35 patients were treated using a non-compressive dressing. The patients were followed up for an average of 10.3 months. In all patients, a hemovac suction drain was inserted postoperatively. Results: The mean level of bleeding was 626.6 mL in the compressive group and 693.8 mL in the non-compressive group. There was no statistical difference between the two groups (P=0.416). Moreover, the incidence of postoperative complications including dislocation, nerve injury, symptomatic deep vein thrombosis and heterotopic ossification was similar in both groups. Conclusion: These results suggest that the compressive dressing has no significant effect on the amount of postoperative bleeding and clinical results after total hip arthroplasty.

OBJECTIVE: Tamoxifen is a nonsteroidal hormone that functions as a selective estrogen-receptor (ER) modulator in breast tissue. It is the first-choice drug for the postoperative treatment of ER-positive breast cancer patients. However, tamoxifen, if administered for a prolonged duration, has estrogen-like effects on the uterus, leading to an increased risk for the development of endometrial diseases such as endometrial hyperplasia, endometrial polyp, and endometrial cancer. This study was designed to investigate the effects of tamoxifen treatment on endometrium in breast cancer patients. METHODS: Fifty-five tamoxifen-treated breast cancer patients visited an outpatient gynecology clinic. We analyzed the endometrial pathology with consideration to the duration of tamoxifen treatment the patient symptoms and the endometrial thickness, as measured by transvaginal ultrasonography. Endometrial polypectomy was performed to obtained polyps from women presenting with abnormal bleeding (17 polyps from postmenopausal women who had not been treated with tamoxifen and 14 from women who had been treated with this drug). To investigate the effects of tamoxifen treatment on the endometrial polyps, we performed immunohistochemical staining for ER, the progesterone receptor (PR), and Ki67 on the polyps obtained from both groups of women. RESULTS: In 29 (52.7%) of 55 tamoxifen-treated breast cancer patients, the endometrium was more than 10 mm thick, and in 19 (65.5%) of these patients, the abnormalities noted comprised 11 endometrial polyps, 5 endometrial carcinomas, 2 submucosal myomas, and 1 endometrial hyperplasia. The incidence of endometrial proliferation was significantly higher in patients who had been treated with tamoxifen for less than 1 year (P=0.037) than in those who had been treated for more than 1 year. Although the endometrial carcinomas, submucosal myomas, and endometrial hyperplasia were found in the patients who had been treated for more than 1 year, this result was not statistically significantwhen compared with the other group. As compared to the endometrial polyps obtained from women who had not received tamoxifen treatment, those obtained from patients who had received the treatment exhibited significantly lower levels of ER expression (P=0.000) in the glands and increased levels of PR (P=0.031) and Ki-67 expression (P=0.000) in the stroma. CONCLUSIONS: During tamoxifen treatment for breast cancer, the endometrial pathology should be investigated if transvaginal ultrasonography reveals the tissue to be more than 10 mm thick. Although tamoxifen has significant effects on the expression of hormone receptors, the mechanism underlying the development of endometrial polyps does not appear to be mediated by the ER.

BACKGROUNDS/AIMS: Complete elimination of intrahepatic duct (IHD) stones is difficult and IHD stone disease is frequently associated with various complications, recurrence and sometimes cholangiocarcinoma. Therefore, we analyzed the long-term surgical results and evaluated the management currently considered appropriate. METHODS: Overall 110 patients who had been diagnosed with benign IHD stone disease and who underwent surgical treatment were enrolled in this study. The patients were categorized into three groups according to the type of surgery performed; liver resection (LR) group, intrahepatic duct exploration (IHDE) group and hepaticoenterostomy (HE) group. We compared and analyzed the results of these three groups. RESULTS: The number of cases in the LR group, IHDE group and HE group were 77, 25 and 8 respectively. The LR group required a longer operation time (p=0.000), more frequent transfusion (p=0.028) and had higher morbidity (p=0.049). However, the LR group had a higher clearance rate (90.9%) (p=0.000) than the other groups. In addition, there were a total of 22 cases of IHD stone recurrence during the follow-up, but there was no statistically significant difference among the three groups. The location of IHD stones was related to a risk factor for incomplete stone removal, but not for recurrence. CONCLUSION: The fundamental principle for the treatment of IHD stone disease should be liver resection. However, it can lead to a longer operative time and higher rate of complications than the other procedures. There is also no difference in the IHD stone recurrence rate among the procedures. Therefore, these alternative and minor procedures could also be taken into account for patients with poor preoperative condition.

BACKGROUND/AIMS: The indications for colorectal endoscopic submucosal dissection (ESD) vary in clinical practice. To establish colorectal ESD as a standard treatment, standard indications are essential. For establishing standard indications for colorectal ESD, we surveyed the preferences and criteria of endoscopists for colorectal ESD in their practices. METHODS: A multiple-choice questionnaire was sent to 27 members of the Korean Society of Gastrointestinal Endoscopy/ESD group. The indications of endoscopists for selecting ESD as a treatment for colorectal tumors ≥2 cm in diameter were surveyed. RESULTS: On the basis of the preprocedural assessment of histology, adenoma with high-grade dysplasia, mucosal cancer, and shallow submucosa invasive cancer were included in the indication for ESD. Based on gross morphology, laterally spreading tumor (LST) granular nodular mixed type, LST-nongranular (LST-NG) flat elevated type, and LST-NG pseudodepressed type were included. On the basis of the pit pattern by Kudo classification, types III, IV, and V-I were included. Based on the narrow band imaging pattern by Sano classification, types II and III-a were included. Other lesions, such as sporadic localized tumors in chronic inflammation and local residual early carcinoma after endoscopic resection, were also included in the indication for ESD. CONCLUSIONS: The indications of Korean endoscopists for colorectal ESD are broader than those in recent guidelines, and tend to include more benign-looking tumors. To find the appropriate indications for colorectal ESD, systematic data collection and analysis are required to reach a consensus in a timely manner.

Whether immunosuppressive therapy may have beneficial effects in the treatment of IgA nephropathy remains controversial. ACE inhibitor or angiotensin II receptor antagonist(AIIA) are suggested to reduce urinary protein excretion(Up) in patients with renal diseases. We therefore investigated the effects of the angiotensin II receptor antagonist losartan on the proteinuria and renal function in patients with IgA nephropathy. AIIA reduced blood pressure in patients with hypertension, but there were no significant differences statistically before and after therapy. AIIA reduced Up after 1-4 months(2.8+/-1.1 to 1.1+/-1.0g/24h, p=0.001) and 7-13 months(2.8+/-1.1 to 1.7+/-0.6g/24h, p=0.017). There were no significant changes of serum creatinine levels after AIIA treatment. Cough or angioedema were not observed during AIIA treatment. In conclusion, AIIA may be useful in the treatment of patients with IgA nephropathy and proteinuria.
