Melanosis coli is the brownish black discoloration of the colon due to accumulation of pigment containing macrophages in lamina propria. The nature and source of this pigment is controversial but many studies have suggested that the pigment is related to lipofuscin. Melanosis coli has been reported to be closely associated with prolonged administration of anthraquinone purgatives. But this condition is sometimes associated with colonic polyp colon cancer, rediation therapy or non-anthraquinone purgatives administration. Moreover the fact that melanosis coli could be found in subjects who never used purgatives suggested that, even though chronic consumption of anthraquinone purgatives seems to play a major role, other factors may be involved in the pathogenesis of melanosis coli. We presented a case of melanosis Coli in a 47-year-old female with history of rectal instillation of petroleum for control of hemorrhoids.

Gastric lymphoma occupies about 1-7% of gastric cancer and is the most common type of extranodal lymphoma. To evaluate the endoscopic morphologic characteristics of gastric lymphoma, we analysed the endoscopic findings in 45 patients with pathologically-proven gastric lymphoma. (continue...)

Background/Aims:
Utilization of low-volume preparation agents is crucial to improve patient willingness to undergo repeat colonoscopies. However, gastric safety data on preparation agents are limited. This study evaluated the acute gastropathy associated with bowel preparation agents.
Methods:
This retrospective study enrolled healthy subjects who underwent both esophagogastroduodenoscopy and colonoscopy screening. Baseline patient characteristics, bowel preparation success, acute gastropathy, and polyp and adenoma detection rates were evaluated for 1 L polyethylene glycol with ascorbic acid (1 L PEG/Asc) and oral sulfate tablet (OST) groups.
Results:
Comparison of the OST group (n=2,463) with the 1 L PEG/Asc group (n=2,060) revealed that the rates of successful cleansing and high-quality cleansing were similar between the two groups. Polyp and adenoma detection rates were significantly higher in the OST group than in the 1 L PEG/Asc group (p<0.001 and p=0.013), while the incidence of acute gastric mucosal lesion-like blood stain/clot, erosions at greater curvature side of antrum/body, multiple erosions, and overlying mucosal erythema or edema were all significantly higher in the OST group than in the 1 L PEG/Asc group (all p<0.001). Additionally, high and indeterminate probability scores of preparation agent-induced gastropathy (p=0.001) and mean Lanza scores were significantly higher in the OST group than in the 1 L PEG/Asc group (1.3 vs. 0.4, p<0.001).
Conclusions
Compared with 1 L PEG/Asc, OSTs were significantly associated with acute gastropathy during bowel preparation, thus requiring careful consideration from physicians for the simultaneous screening of EGD and colonoscopy.

PURPOSE: The purpose of this study was to compare the surgical outcomes of two different surgical methods for varicocelectomy, and to assess the effects of varicocelectomy on semen parameters in subinfertile men. MATERIALS AND METHODS: This study included 63 patients with clinically palpable varicocele and abnormal semen parameters who underwent varicocelectomy. Thirty-three patients underwent laparoscopic varicocelectomy, and 30 received microsurgical inguinal varicocelectomy. Semen analyses were performed 5.3 months later, and compared with the pre-operative data. RESULTS: The mean age of patients was 32.1+/-1.3 years old. Comparison of the semen parameters between pre and post-varicocelectomy revealed significant improvement in the sperm count (p<0.05). In laparoscopic and microsurgical inguinal varicocelectomy, the sperm counts were increased from 16.2+/-4.3 to 30.6+/-7.5 and from 15.4+/-3.8 to 37.5+/-7.7, respectively. Sperm motility also tended to improve. CONCLUSIONS: Varicocelectomy enhanced semen parameters after both laparoscopic and microsurgical methods. In subfertile men, early varicocelectomy is recommended.

Colonic palyps are one of the most risky factors for colon cancer. The pathology of the specimen obtained by forceps biopsy does not represent the whole specimen of the polyp obtained by polypectomy or surgery in some cases. To evaluate these pathologic differences. we analysed the 39 patients with colonic polyps who underwent forceps biopsy and polypectomy. (continue...)
