OBJECTIVE: To determine inter- and intraobserver agreement, diagnostic accuracy and the learning curve required for interpreting the 'sliding sign' and predicting pouch of Douglas (POD) obliteration. METHODS: This was an inter-/intraobserve…

To determine whether the presence of transvaginal sonographic (TVS) soft markers of ovarian mobility, site specific tenderness (SST) are significantly associated with endometriosis type and location at surgery. Multicentre prospective obser…

To determine the prevalence of ovarian immobility with endometriomas as well as the diagnostic accuracy of transvaginal sonographic (TVS) ovarian mobility in both the presence and absence of endometriomas. Multicentre prospective observatio…

To develop and validate a preoperative ultrasound based staging system to predict laparoscopic level required for endometriosis surgery. Multicentre study of consecutive women presenting with chronic pelvic pain from January 2009 to March 2…

We read with interest the comments from Noventa et al. regarding the difficulty in identifying the best ‘first-line’ approach for the diagnosis of site-specific deep infiltrating endometriosis (DIE) of the posterior compartment. Indeed, the…

OBJECTIVE: To use office gel sonovaginography (SVG) to predict posterior deep infiltrating endometriosis (DIE) in women undergoing laparoscopy. METHODS: This was a multicenter prospective observational study carried out between January 2009…

OBJECTIVES: To determine the correlation between historical variables at presentation with the phenotype and location of biopsy proven endometriosis at laparoscopy. METHODS: Prospective observational study. Consecutive women had laparoscopi…

To evaluate the real time dynamic sliding sign in the prediction of POD obliteration in women undergoing laparoscopy for suspected endometriosis. A multi-centre prospective observational study with 200 women. All women underwent a transvagi…

To determine whether the presence of site-specific tenderness during transvaginal scan (TVS) corresponds with the location of peritoneal endometriosis at laparoscopy in women with normal POD and no deep infiltrating endometriosis. Multi-cen…

To determine whether there is an association between pouch of Douglas (POD) obliteration at laparoscopy and site specific tenderness during TVS. Multi-center prospective observational study undertaken from January 2009 to February 2013. All…

To correlate an ultrasound based staging system for endometriosis with the level of laparoscopic training required for endoscopic management. Review of 200 patients with complete ultrasound and surgical data. Based on ultrasonographic featu…

To determine whether there is an association between specific symptoms and surgical findings in women with suspected endometriosis. Multi-center prospective observational study undertaken from January 2009 to February 2013. All women includ…

To determine the accuracy of office gel sonovaginography in predicting the depth of infiltration of bowel DIE. A retrospective review of 20 patients who had segmental resections for bowel endometriosis over a 4 year period. Each patient had…

Objectives: Cerebral white matter injury, consisting primarily of periventricular leukomalacia (PVL) and periventricular hemorrhagic infarction (PVHI) is well-described in premature infants. However, typical lesions of PVL and PVHI are unco…

To generate and evaluate new mathematical models to predict POD obliteration in women scheduled for laparoscopy with suspected endometriosis. Multi-centre prospective study (Jan 09–Feb 13). Women with chronic pelvic pain (CPP) +/− history o…

In a recent study by Hudelist et al, UOG 2013, the authors concluded that the “uterine sliding sign” demonstrated by transvaginal sonography (TVS) was a simple predictor of deep infiltrating endometriosis (DIE) of the rectum in patients wit…

To determine whether the presence of site-specific tenderness during TVS corresponds with the location of peritoneal endometriosis at surgery for women with suspected endometriosis. Multi-centre prospective observational study undertaken fr…

To evaluate the relationship between the position of uterus on transvaginal ultrasound (TVS) and the presence of deep infiltrating endometriosis (DIE) at laparoscopy. Multi-centre prospective study (Jan 09-Feb 13). Women with chronic pelvic…

To determine the association between the presence of pouch of Douglas (POD) obliteration at transvaginal ulatrsound (TVS) and surgical findings at laparoscopy in women with endometriosis. Multi-centre prospective observational study underta…

STUDY QUESTION: What is the inter-/intra-observer agreement and diagnostic accuracy among gynaecological and non-gynaecological ultrasound specialists in the prediction of pouch of Douglas (POD) obliteration (secondary to endometriosis) at …

To use sonovaginography (SVG) to predict endometriosis location and severity in women planned for laparoscopic endometriosis surgery. Ongoing, multi-centre prospective observational study (June 2009–November 2011). All women included were o…
