The provided text does not contain the abstract or body of a research paper regarding bowel preparation and transvaginal ultrasound. Instead, it displays a security challenge page from a website administrator using Anubis to prevent automated scraping by AI companies. The text explains that this Proof-of-Work scheme is intended to reduce server load from mass scrapers while legitimate users are identified via browser fingerprinting. It also notes that modern JavaScript features are required to bypass this challenge, warning against disabling them with certain plugins. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

STUDY OBJECTIVE: To compare the accuracy of transvaginal ultrasound (TVUS) with and without bowel preparation (BP) to detect and describe intestinal nodules of deep infiltrating endometriosis (DIE) with laparoscopic findings. DESIGN: A prospective study of paired data (Canadian Task Force classification II.1). SETTING: A tertiary university hospital from November 2014 to November 2015. PATIENTS: A cohort of women awaiting surgery for endometriosis. INTERVENTIONS: The wall of the rectum and the lower sigmoid colon of the patients were evaluated by 2 TVUSs: the first ultrasound was performed without previous BP, and the second was done after a 3-day low-residue diet and two 250-mL enemas 12 hours and 3 hours before TVUS. MEASUREMENTS AND MAIN RESULTS: The presence or absence of rectosigmoid nodules visualized by TVUS with and without BP was compared with laparoscopic results. Forty patients with a mean age of 36.8 ± 5.0 years were included in the study. By comparing the surgical findings histologically confirmed (the presence or absence of bowel nodules and localization) with those of the 2 TVUSs with and without BP, the sensitivity, specificity, and Cohen kappa were 100%, 96%, and 0.95 and 73%, 88%, and 0.61, respectively. Laparoscopy showed that up to 37.5% of patients (15/40) presented bowel involvement. Variables were clearly more evaluable with than without BP. CONCLUSION: TVUS with BP has a higher accuracy than TVUS without BP. BP allows and facilitates the detection of more rectal nodules of DIE in patients with suspected endometriosis and surgical criteria.

Making sure you're not a bot! Loading... You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites. This can and does cause downtime for the websites, which makes their resources inaccessible for everyone. Anubis is a compromise. Anubis uses a Proof-of-Work scheme in the vein of Hashcash, a proposed proof-of-work scheme for reducing email spam. The idea is that at individual scales the additional load is ignorable, but at mass scraper levels it adds up and makes scraping much more expensive. Ultimately, this is a placeholder solution so that more time can be spent on fingerprinting and identifying headless browsers (EG: via how they do font rendering) so that the challenge proof of work page doesn't need to be presented to users that are much more likely to be legitimate. Please note that Anubis requires the use of modern JavaScript features that plugins like JShelter will disable. Please disable JShelter or other such plugins for this domain.
