Outcomes of surgical treatments for rectovaginal fistula and prognostic factors for successful closure: a single-center tertiary hospital experiences.

Conclusion: Radiation therapy and pelvic operation for cancer were more common causes than birth injury, and these causes of rectovaginal fistula were the most important prognostic factors. An individualized approach and repeated surgeries with complex or newly developed procedures, even among high-risk causes of fistula, may be necessary to achieve successful closure.

The Crohn’s-like lymphoid reaction (CLR) to colorectal cancer (CRC), a CRC-specific ectopic lymphoid reaction, is thought to play an important role in the host response to CRC. CLR is characterized by peritumoral lymphocytic aggregates that are found at the advancing edge of the tumor. Spatial and molecular characterization of CLR within the tumor microenvironment (TME) have uncovered a spectrum of peritumoral lymphoid aggregates with varying levels of organization and maturation. In early stages of CLR development, CD4+ T-cells cluster predominantly with mature antigen presenting dendritic cells. As CLR matures, inc...

Abstract Patients with long-standing inflammatory bowel disease (IBD) involving at least 1/3 of the colon are at increased risk for colorectal cancer (CRC). Advancements in CRC screening and surveillance and improved treatment of IBD has reduced CRC incidence in patients with ulcerative colitis and Crohn's colitis. Most cases of CRC are thought to arise from dysplasia, and recent evidence suggests that the majority of dysplastic lesions in patients with IBD are visible, in part thanks to advancements in high definition colonoscopy and chromoendoscopy. Recent practice guidelines have supported the use of chromoendo...

Abstract Estrogens play important roles in the development and progression of multiple tumor types. Accumulating evidence points to the significance of estrogen action not only in tumors of hormonally regulated tissues such as the breast, endometrium and ovary, but also in the development of colorectal cancer (CRC). The effects of estrogens in physiological and pathophysiological conditions are mediated by the nuclear estrogen receptors α and β, as well as the membrane-bound G protein-coupled estrogen receptor (GPER). The roles of GPER in CRC development and progression, however, remain poorly understoo...

Authors: Chams S, Badran R, Sayegh SE, Chams N, Shams A, Hajj Hussein I Abstract Inflammatory bowel disease is a chronic inflammatory condition that encompasses Crohn's disease and ulcerative colitis. Inflammatory bowel disease is not exclusive to the gastrointestinal system, as it has been identified to be associated with extraintestinal manifestations that encompass every other organ system in the human body. This review article will comprehensively review the current knowledge on extraintestinal manifestations of inflammatory bowel disease. In addition, it will discuss the recommendations for screening and surve...

Authors: Chou JW, Lai HC, Chang CH, Cheng KS, Feng CL, Chen TW Abstract The incidence and prevalence of inflammatory bowel disease (IBD) are low but increasing in Taiwan. We aimed to investigate the epidemiology and clinical outcomes of IBD in central Taiwan. We retrospectively analyzed patients with IBD diagnosed at our hospital between January 2000 and September 2018. The diagnostic criteria were based on endoscopic and pathologic findings. Clinical characteristics, treatment regimens, and treatment outcomes were analyzed. A total of 190 patients with IBD were enrolled (80 with Crohn's disease (CD) and 110 with u...

This study was a secondary analysis of an RCT of 92 Crohn's disease patients in remission (49% female, median age  = 44). Participants were randomized to 2000 IU day−1 of vitamin D3 or placebo for 1 year, with 25 ‐hydroxyvitamin D (25(OH)D) being measured at baseline and every 4 months. Based on participant's place of residence, daily ambient UVB dose at wavelengths that can induce vitamin D synthesis (D‐UVB) was obtained. Cumulative and weighted ambient D‐UVB (cw‐D‐UVB) exposure prior to each blo od draw was calculated for each participant. Linear regression analysis and multilevel...

Abstract BACKGROUND AND AIM: Fecal calprotectin has successfully been widely recommended as a sensitive biomarker of inflammatory bowel diseases (IBD). Recently, we have identified an excellent new fecal biomarker, B-cell activating factor (BAFF), as effective as fecal calprotectin for diagnosing intestinal inflammation. Here in this study, we sought to investigate the potential of fecal BAFF as a screening marker for gastrointestinal inflammation and neoplasms in patients with abdominal discomfort. METHODS: 230 patients with abdominal discomfort were prospectively enrolled into this study and fecal samples w...

Abstract BACKGROUND: Different histological growth patterns (HGPs) of colorectal carcinoma (CRC) liver metastasis are associated with patients' prognosis and response to antiangiogenic therapy. However, the relationship between HGPs of liver metastasis and clinicopathological and genomic characteristics of primary cancer has not been well established. AIM: To assess whether certain clinicopathological and genomic features of primary CRC could predict the HGPs of liver metastasis. METHODS: A total of 29 patients with paired resections of both primary CRC and liver metastasis were divided into two groups: ...

Conclusion: In this large population-based cohort study, birth weight and childhood growth did not influence risk of IBD, which contrasts with observations in other chronic diseases. Thereby, the study also suggests that pre-clinical effects of adult IBD are not measurable in childhood and that childhood risk factors for IBD do not influence growth.
