| 1 | Comparison of non-schistosomal rectosigmoid cancer and schistosomal rectosigmoid cancer显示文摘AIM: To compare the clinicopathological features of patients with non-schistosomal rectosigmoid cancer and schistosomal rectosigmoid cancer.METHODS: All the patients with rectosigmoid carcinoma who underwent laparoscopic radical surgical resection in the Shanghai Minimally Invasive Surgical Center at Ruijin Hospital affiliated to Shanghai JiaoTong University between October 2009 and October2013 were included in this study. Twenty-six cases of colonic schistosomiasis diagnosed through colonoscopy and pathological examinations were collected. Symptoms,endoscopic findings and clinicopathological characteristics were evaluated retrospectively.RESULTS: There were no significant differences between patients with and without schistosomiasis in gender, age, CEA, CA19-9, preoperative biopsy findings or postoperative pathology. Patients with rectosigmoid schistosomiasis had a significantly higher CA-125 level and a larger proportion of these patients were at an early tumor stage(P = 0.003). Various morphological characteristics of schistosomiasis combined with rectosigmoid cancer could be found by colonoscopic examination: 46% were fungating mass polyps, 23%were congestive and ulcerative polyps, 23% were cauliflower-like masses, 8% were annular masses.Only 27% of the patients were diagnosed with rectal carcinoma preoperatively after the biopsy. Computed tomography(CT) scans showed thickened intestinal walls combined with linear and tram-track calcifications in 26 patients.CONCLUSION: Rectosigmoid carcinoma combined with schistosomiasis is associated with higher CA-125 values and early tumor stages. CA-125 and CT scans have a reasonable sensitivity for the accurate diagnosis. | Hao Feng Ai-Guo Lu Xue-Wei Zhao Ding-Pei Han Jing-Kun Zhao Lei Shi Tobias S Schiergens Serene ML Lee Wen-Peng Zhang Wolfgang E Thasler | 2015 | World Journal of Gastroenterology2015，21，23： | 6 |
| 2 | Colonoscopic yield of colorectal neoplasia in daily clinical practice显示文摘AIM:To assess the prevalence and location of ad-vanced neoplasia in patients undergoing colonoscopy,and to compare the yield per indication.METHODS:In a multicenter colonoscopy survey (n = 18 hospitals) in the Amsterdam area (Northern Holland),data of all colonoscopies performed during a three month period in 2005 were analyzed. The location and the histological features of all colonic neoplasia were recorded. The prevalence and the distribution ofadvanced colorectal neoplasia and differences in yield between indication clusters were evaluated. Advanced neoplasm was defi ned as adenoma > 10 mm in size,with > 25% villous features or with high-grade dyspla-sia or cancer.RESULTS:A total of 4623 eligible patients underwent a total colonoscopy. The prevalence of advanced neo-plasia was 13%,with 281 (6%) adenocarcinomas and 342 (7%) advanced adenomas. Sixty-seven percent and 33% of advanced neoplasia were located in the distal and proximal colon,respectively. Of all patients with right-sided advanced neoplasia (n = 228),51% had a normal distal colon,whereas 27% had a syn-chronous distal adenoma. Ten percent of all colono-scopies were performed in asymptomatic patients,7% of whom had advanced neoplasia. In the respective procedure indication clusters,the prevalence of right-sided advanced neoplasia ranged from 11%-57%. CONCLUSION:One out of every 7-8 colonoscopies yielded an advanced colorectal neoplasm. Colonoscopy is warranted for the evaluation of both symptomatic and asymptomatic patients. | Jochim S Terhaar sive Droste Mike E Craanen Rene WM van der Hulst Joep F Bartelsman Dick P Bezemer Kim R Cappendijk Gerrit A Meijer Linde M Morsink Pleun Snel Hans ARE Tuynman Roy LJ van Wanrooy Eric IC Wesdorp Chris JJ Mulder | 2009 | World Journal of Gastroenterology2009，15，9： | 6 |
