Internal hernias, protrusion of abdominal viscera into an intraperitoneal fossa, are uncommon causes of bowel obstruction, and preoperative diagnoses are difficult. We report a rare case of a 47-year-old female with strangulated small bowel obstruction secondary to an intramesosigmoid hernia preoperative diagnosis by multi-detector row computed tomography. We highlight the preoperatively diagnosed value and findings of MDCT in intramesosigmoid hernia.
Right paraduodenal hernia is a very rare cause of abdominal pain. It can lead to bowel obstruction, ischemia, and perforation with a high mortality. A timely and correct diagnosis with a rapid diagnostic tool is mandatory. However, clinical diagnosis of right paraduodenal hernia is difficult for its nonspecific symptoms. Traditionally, paraduodenal hernia was diagnosed by small bowel series that was a time-consuming image study. We report a case of right paraduodenal hernia with pre-operative fast diagnosis by multidetector row computed tomography. Fortunately, the ischemic bowel loops were timely alleviated by reduction and resection was prevented.
The objective of this study was to estimate the subsequent cancer risk of women after receiving hysterosalpingography (HSG) by conducting a nationwide retrospective cohort study. We identified a study cohort of 4,371 patients who had had a HSG examination and a comparison cohort of 17,484 women without HSG examination between 1998 and 2005. Both cohorts were followed up with until the end of 2010 to measure the incidence of cancer. The risk of developing cancer for patients with HSG was assessed using the Cox proportional hazard model. In the multivariate analyses, the HSG cohort did not have a significantly greater risk of cancer (Hazard Ratio [HR] = 1.02, 95% CI = 0.79-1.31) than the non-HSG cohort. The HR was highest for genital cancer (HR = 1.32, 95% CI = 0.77-2.25), followed by urinary system cancer (HR = 1.11, 95% CI = 0.23-5.40), and abdominal cancer not involving the GU system (HR = 1.04, 95% CI = 0.53-2.03), all of which were non-significant elevations. The cancer incidence rates, especially that for urinary system cancer, were increased in the HSG cohort, but the increase in cancer incidence was small and not statistically significant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
