Histopathological characterization of cholecystectomy specimens in patients with inflammatory bowel disease
ABSTRACT Inflammatory bowel disease is associated with increased risk of cholelithiasis. However, the histologic patterns in gallbladders have not been extensively studied. This study is designed to characterize the histopathologic features of cholecystectomy specimens in inflammatory bowel disease patients, compared to a control group.
Cholecystectomy specimens in 78 Crohn's disease patients and 50 ulcerative colitis patients were reviewed. These were compared with 93 cholecystomies from noninflammatory bowel disease patients of approximate age and sex. The pattern and extent of inflammation was noted.
Marked chronic cholecystitis was present in 12% of ulcerative colitis patients (P<0.05) and 10.3% of Crohn's disease patients (P>0.05), compared to 4.3% of the noninflammatory bowel disease control group. Eight percent of ulcerative colitis patients (P<0.05) and 2.6% of Crohn's disease patients (P>0.05) had acute serositis, compared to 0% of the noninflammatory bowel disease control. The third inflammatory pattern, nodular lymphoid aggregates, was significantly increased in Crohn's disease patients after adjusting for the effect of cholelithiasis. Nodular lymphoid aggregates were found in 21.2% of Crohn's disease patients and 9.7% of ulcerative colitis patients without cholelithiasis, compared to 5% of noninflammatory bowel disease controls without cholelithiasis, a statistically significant difference between the Crohn's disease and control groups (P<0.05).
Inflammatory bowel disease patients show similar inflammatory patterns in cholecystectomy specimens compared to the general population. However, two inflammatory patterns that occur more often in ulcerative colitis patients are marked chronic cholecystitis and acute serositis, while nodular lymphoid aggregates are more common in Crohn's disease patients.

ABSTRACT: Primary gallbladder (GB) carcinoma and Crohn's disease (CD) of the GB are individually rare. We present a case of a pregnant woman with CD found to have GB involvement and primary GB carcinoma. A 34-year-old female at 6 wk gestation with a 21 year history of CD of uncertain extent presented with 3 mo of diarrhea, urgency and abdominal pain. During work-up, she was found to have elevated transaminases and an abnormal alkaline phosphatase. Imaging revealed two gallbladder polyps both greater than 1 cm in size. Resection and histological evaluation was consistent with Crohn's involvement of the GB, poorly differentiated adenocarcinoma of the GB with invasion through the muscularis propria and matted lymph nodes in the porta hepatis positive for metastatic carcinoma (stage pT2N1). Six cases of CD involving the GB, two cases of primary GB carcinoma in CD, and ten cases of cholangiocarcinoma in pregnancy have been published. This is the only case that describes all three factors. Common features in CD of the GB include acute cholecystitis, ileal involvement, and presence independent of active intestinal disease. Common features in CD patients with GB malignancy include younger age of detection, a long history of CD, extensive colonic and ileal involvement of disease, the absence of cholelithiasis, and pre-existing gallbladder disease (primary sclerosing cholangitis and gallbladder polyps). Pregnancy is specific to this case. The role of CD in the development of GB malignancy is not well understood nor is the contribution of pregnancy to the spread of disease. Chronic inflammation and immunosuppression compounded by hormonal influence is implicated.02/2013; 5(2):29-33. DOI:10.4251/wjgo.v5.i2.29

ABSTRACT: The relationship between motility and inflammatory gastrointestinal disorders is at the same time complex and intriguing since these conditions might share some genetic, environmental, immunological and microbial predisposing factors. In addition, significant symptom overlapping may occur, muddling the waters within the clinical context. Although on one hand this represents a challenge for the clinician for a potential under- or over-treatment and diagnostic delay, on the other hand it possibly represents an opportunity for the researcher to better disclose the intimate relationship between chronic (often low-grade) inflammation, motor disorders and deranged sensory function. The best example is probably represented by Crohn's disease and ulcerative colitis. In fact, a number of gastrointestinal motor disorders have been described in association with these diseases, disorders which span from the esophagus to the anorectum, and which will be extensively covered in this review. It is conceivable that at least part of this derangement is strictly related to inflammatory cytokine trafficking and neuromuscular changes; however, given the high prevalence of functional gastrointestinal disorders in the general population, this overlap might also be serendipitous. However, it is worth noting that literature data on this topic are relatively scarce, sometimes quite outdated, and mostly focused on the interplay between irritable bowel syndrome and inflammatory bowel disease. Nevertheless, both researchers and clinicians must be aware that symptoms related to gastrointestinal motility disorders may be highly prevalent in both active and inactive inflammatory bowel disease, correlate with greater psychological comorbidity and poorer quality of life, and may negatively influence the therapeutic approaches.World Journal of Gastroenterology 01/2014; 20(1):37-44.

ABSTRACT: The relationship between Crohn's disease and gallstones is established. However, the prevalence and risk factors for gallstones in patients with ulcerative colitis (UC) are not yet well understood. The aim of this study was to evaluate the prevalence and risk factors of gallstones in patients with UC. This study was a retrospective single center study. A total of 87 patients with UC and 261 healthy controls were enrolled. Age, sex, and body mass index were matched. To investigate risk factors, the extent of UC, duration of disease, number of hospital admissions, and number of steroid treatments in patients with UC were evaluated. The prevalence of gallstones in patients with UC was 13.8%, whereas that in healthy controls was only 3.1% (P<0.001). For patients with UC, patients ≥50 years of age had a 3.6-times higher risk of gallstones compared to that in those <50 years of age, and the difference was statistically significant (odds ratio, 3.60; confidence interval, 1.03-12.61) in univariate analysis. There were no statistically significant disease-related risk factors for gallstones in UC patients. This is the first study of gallstone prevalence in Korean UC patients. In this study, patients with UC had a higher prevalence of gallstones compared to that in well-matched healthy controls. Age seemed to be a possible risk factor, and more studies are needed. Further prospective, large-scale studies will be required to confirm the risk factors for gallstones in UC patients.04/2015; 13(2):122-7. DOI:10.5217/ir.2015.13.2.122
