Diseases of the Colon and Rectum | Year: 2010

PURPOSE: Our aim was to explore possible causes of rectal perforation occurring in patients who undergo the procedure for prolapse and hemorrhoids. METHODS: We evaluated data from cases of rectal perforation that occurred after the procedure for prolapse and hemorrhoids in China in conjunction with case reports from the international medical literature. RESULTS: We identified 7 patients from 5 hospitals in 2 provinces of China who had rectal perforation after the procedure despite having received prophylactic antibiotic treatment. Two patients had a disrupted staple line and 5 had perforations on the rectum wall above the intact staple line. Six patients presented with symptoms in the first 3 days after the procedure. Three patients had concomitant disease: 1 had concomitant constipation and internal rectal prolapse, 1 had concomitant constipation, and 1 had concomitant liver cirrhosis ascites that was not diagnosed preoperatively. Of the 15 cases of rectal perforation found in the literature, 3 patients had an intact staple line and 5 patients had a ruptured staple line. CONCLUSION: The cone-shaped tip of the anvil, concomitant rectal prolapse and pelvic floor descent, and concomitant ascites are possible causes of rectal perforation after the procedure for prolapse and hemorrhoids. © The ASCRS 2010.

Abstract The murine double minute 2 protein (MDM2) and TP53 interact in regulating cell cycle, DNA repair and apoptosis process, which is crucial in carcinogenesis. Since functional variations in these two genes were shown to change gene expression and function, we hypothesized that potentially functional polymorphisms in these genes may contribute to colorectal cancer (CRC) susceptibility. A hospital-based case-control study consisting of 444 patients and 569 controls was conducted to explore the associations between TP53 Arg72Pro and MDM2 T309G and CRC risk in Chinese. The combined effect of TP53 Arg72Pro and MDM2 T309G was significant in a gene dose-response increasing CRC risk (trend test: P = 0.02). Individuals carrying 3 or more potential risk alleles had 1.78 times risk (95 % CI: 1.13-2.80) to develop CRC compared with individuals without potential risk allele. This increased cancer risk was more pronounced in smokers who carried 3-4 potential risk alleles (OR = 2.75, 95 % CI: 1.14-6.60) and in young subjects (OR = 2.05, 95 % CI: 1.08-3.88). The gene-gene interaction between TP53 Arg72Pro and MDM2 T309G may interact in carcinogenesis of CRC in Chinese, especially in smokers, and this kind of interaction is associated with onset age of CRC. © Springer Science+Business Media B.V. 2012.
