BACKGROUND Laparoscopic surgery for anorectal carcinoma is steadily gaining acceptance. While feasibility has already been reported, there are no reports addressing the impact of the actual size of large tumors on laparoscopic resectability. AIM To assess the feasibility and short-term results (including oncological surrogate end points) of performing laparoscopic abdomino-perineal resection ...

colorectal lymphoma is an extremely rare disease, representing less than 0.5% of all primary colorectal neoplasms. the disease is usually diagnosed in the advanced stages because of its primary non-specific symptoms. the most common involved site is cecum followed by rectum and ascending colon. diffuse large b-cell lymphoma is a more frequent subtype. although surgical resection is often techni...

OBJECTIVES The purpose of the study was to identify predictive factors of tumor response to preoperative chemoradiotherapy for rectal adenocarcinoma. METHODS Ninety-eight patients with nonmetastatic rectal adenocarcinoma received preoperative concurrent chemoradiotherapy and underwent mesorectal excision. After treatment, tumor response according to tumor regression grade were evaluated. The ...

Background: Escherichia coli (E. coli) is one of the most important infectious agents in patients undergoing prostate biopsy. It belongs to a large family of gram-negative rods, Enterobacteriaceae. This family includes members of the normal flora of the intestine that are only occasionally pathogenic. Recent considerations of rectal colonization with fluoroquinolone-resistant E. coli shows the ...

PURPOSE Mucinous adenocarcinomas account for about 10% of all colorectal cancers. This study aimed to investigate the prognostic impact of mucinous histologic subtype on oncologic outcomes in patients with colorectal cancer. METHODS This retrospective study was performed at two large tertiary university hospitals. We analyzed the characteristics, prognostic factors, and survival of patients w...

Our goal was to explore the factors influencing the visualization of anterior peritoneal reflections (APRs) using rectal MRI. We evaluated the usefulness of rectal MRI in measuring the distance from the anal verge to the APR and determining the relationship between the APR and the rectal tumor. Clinical and imaging data from 319 patients who underwent surgery after MRI examination between Octob...

BACKGROUND Angiogenesis plays a pivotal role in malignant tumor progression. The count of blood microvessels of the tumor has been recognized as an indicator of malignant potential of the tumors and provides the ability to predict tumors recurrence. The role endoglin in the Dukes B rectal cancer is still unexplored. The aims of this study were to examine immunohistochemical expression of endogl...
