PURPOSE: Kidney transplantation is definite treatment in chronic renal failure (CRF). But CRF patients have contracted bladder due to disuse atrophy and fibrosis of bladder mucosa and muscle. Contracted bladder results in CRF itself and failure of transplantation. And this causes many difficulties in ureteroneocystostomy. So many authors suggest that preoperative bladder augmentations of contracted bladder (cystoplasty) using intestine increase success rate in kidney transplantation. But these methods have been usually studied in pediatric transplantation. Preoperative hydrostatic bladder dilatation is nonoperative treatment usually used in interstitial cystitis and hemorrhagic bladder tumor. METHODS: Since January 1996, we newly attempted pretransplant bladder augmentation using hydrostatic pressure in 22 CRF patients who had contracted bladder diagnosed through preoperative voiding cystourethrogram (VCUG). RESULTS: Pre-augmented average bladder volume was 87.7 mL (60~100 mL) and post-augmented bladder volume was 210.5 mL (100~250 mL). There was no complication associated with pretransplant bladder augmentation itself, and there was no transplanted kidney loss. CONCLUSION: These results suggest that pretransplant bladder augmentation using hydrostatic pressure be useful in kidney transplantation of CRF patient who had contracted bladder.

Plasmacytoma is a lymphoid neoplasm with the histological, immunological, and functional features of an immunoglobulin- secreting B cell proliferation. Intestinal involvement may be a manifestation of a diffuse multiple myeloma or less commonly, a primary tumor. Gastric plasmacytomas occur more frequently than intestinal plasmacytomas. We experienced a woman who had a primary extramedullary plasmacytoma that originated in the sigmoid colon. She had suffered from abdominal pain and diarrhea for 4 months and underwent a colonoscopy examination. A colonoscopic biopsy revealed it to be ulcerative colitis, and she underwent a total colectomy as a result. However, the permanent biopsy finding was a plasmacytoma. We review the clinical manifestations, as well as the radiological and histopathological findings of a plasmacytoma.

Objective:
This study aims to evaluate the effect of treatment for great saphenous vein incompetence with a fourth-generation 1940 nm laser with radial fiber and catheter directed foam sclerotherapy (CDFS) without a tumescent simultaneously. The procedure was termed laser assisted sclerotherapy (LAST). It is a kind of thermochemical ablation.
Methods:
From January 1 to June 30, 2023, 86 GSV cases from 50 patients who underwent LAST at Cheongmac hospital were enrolled in this retrospective study. Endogenous laser ablation (EVLA) was performed in the order of accessary vein, tributaries and truncal vein and then followed by CDFS which was performed with a 3% sodium tetradecyl sulfate (STS) mixed with CO 2 gas at a ratio of 1:4. The degree of pain was measured after procedure at 2 hours after the procedure. Follow-up was conducted at 1 week, 1 month, and 6 months.
Results:
Three of the 86 GSV observed for >6 months showed mild reflux. According to size and number of ablated vessels, various energy level was needed. Three percent STS was used 4.5±0.4 cc and operation time per GSV was about 8±2 minutes. The VAS score was 2.5±0.6 at 2 hours after surgery. The closure rate was 100% at 6 months. Symptoms improved after 6 months in all patients (6.2±1.2 to 0.9±0.2).
Conclusion
LAST showed a good closure rate in the early midterm follow up period. Ablation was possible with less energy compared with EVLA and the pain index was lower at the second hour after procedure.

BACKGROUND/AIMS: Endoscopic submucosal dissection (ESD) has been widely performed. However, procedure related-complications and the risk of tumor recurrence are limitations. We analyzed the clinicopathological characteristics of patients who underwent curative additional gastrectomy (gastrectomy) after ESD. METHODS: The clinical characteristics of cases underwent gastrectomy after ESD were retrospectively analyzed. RESULTS: Between January 2002 and August 2010, 1,512 cases underwent ESD for early gastric cancer (n=511) or adenoma (n=1,001). Thirty-two cases (2.1%) underwent gastrectomy after ESD. Thirty cases (2.0%) were EGC and 2 cases (0.1%) were adenoma. Extended indication, larger tumor size and piecemeal resection were risk factors for gastrectomy after ESD. According to the causes of gastrectomy, 13 cases underwent gastrectomy due to complications (40.6%; bleeding in 9, perforation in 4), and 19 cases based on pathological results (incomplete resection in 13, lymphatic invasion in 6). In cases with incomplete resection, the rate of residual tumor and lymph node metastasis after gastrectomy was 69.2% (75% lateral margin, 60% deep and 75% both) and 7.7%, respectively. Three (50%) of the 6 cases with lymphatic invasion had lymph node metatstasis. CONCLUSIONS: The causes of gastrectomy after ESD were the procedure-related complications, the incomplete resection and lymphatic invasion. For complete and curative ESD, endoscopists should try to minimize complications and determine the depth of invasion accurately before ESD.

BACKGROUND/AIMS: It has been known that chronic trauma and inflammation of gallbladder (GB) mucosa by gallstones (GS) can induce epithelial dysplasia, carcinoma in situ, and invasive cancer. This study was designed to investigate the usefulness of cholecystectomy in patients with asymptomatic GS for the early diagnosis and removal of dysplasia or cancer. METHODS: From January 2004 to July 2008, the clinical records of 703 cases with GS who underwent cholecystectomy at Korea University Guro Hospital were reviewed, and the prevalence of dysplasia and cancer was analyzed. RESULTS: In symptomatic GS (542 cases) group, low grade dysplasia was found in 4 cases (0.74%) and high grade dysplasia in 1 case (0.18%). In asymptomatic GS (161 cases) group, low grade dysplasia was found in 4 cases (2.48%) and cancer in 2 cases (1.24%) (p=0.012 vs. symptomatic cases). Dysplasias in symptomatic GS group were not associated with polyps, but dysplasias and cancers in asymptomatic GS group were associated. Patients with asymptomatic GS and polyps were analyzed according to the size of polyps. In those (12 cases) with larger polyps (> or =1 cm), low grade dysplasia was found in 2 cases and cancer in 2 cases. And in those (12 cases) with smaller polyps (<1 cm), low grade dysplasia was found in 2 cases. CONCLUSIONS: Extending indication of prophylactic cholecystectomy in patients with asymptomatic GS without polyp to prevent GB dysplasia or cancer beyond the existing indication does not seem to be justifiable in Korea. However, further studies are needed in patients with asymptomatic GS and polyp of any size.

BACKGROUND/AIMS: Nasogastric administration of cola for dissolution of phytobezoar was reported but the mechanism is not well understood. We aimed to evaluate the efficacy of cola ingestion for upper gastrointestinal endoscopy in patients who have had distal gastrectomy. MATERIALS AND METHODS: Patients were enrolled from July 2007 to October 2007 and all previously received subtotal gastrectomy. We conducted a randomized case-control study which the patients were randomly assigned to two groups. Group A had preparation with cola and group B had no preparation. Cola preparation group ingested about 1,500 mL of cola between 7 PM to 10 PM in the evening before the procedure. Two examiners who were blinded to the type of preparation performed the endoscopy. We assessed the degree of food residue and bile reflux by Japanese classification. RESULTS: A total of 70 patients were included. The comparison of clinical and laboratory characteristics between the two groups showed no statistically significant difference. During endoscopy, food residue was less found in group A than B, but without statistically significance (group A=12.1%, group B=21.6%, P=0.087). However, bile reflux was significantly less found in group A than B (group A=36.4%, group B=67.6%, P=0.015). Multivariate analysis, cola preparation significantly reduced food residue (OR, 0.032; P=0.001) and bile reflux (OR, 0.102; P=0.001). CONCLUSIONS: Preparation with cola in the evening before endoscopic examination may provide a good quality of preparation in patient with remnant stomach after distal gastrectomy.
