Prompt recognition of laparoscopic surgical complications is vital. We present a case highlighting the dangers of relying on plain radiography for exclusion of bowel herniation through a port site. Early recourse to cross-sectional imaging is recommended to avoid such pitfalls.

Background Electrosurgery-induced tubal thermal injury obscures cellular detail and hampers histomorphological assessment for occult pathology. Objective The objectives of this study were to report on diathermy-related thermal injuries to the fallopian tube observed at RRSO and explore its potential impact on the detection of occult tubal epithelial lesions. Design This study was composed of high-risk women from breast and/or ovarian cancer families attending a tertiary high-risk familial gynecologic cancer clinic. This was a retrospective case-control analysis of high-risk women who underwent RRSO. Cases were all women detected to have occult lesions (tubal atypia/carcinoma in situ/cancer) between January 2005 and December 2010. Control subjects were all women with normal tubal/ovarian histology between August 2006 and December 2007. Methods Two pathologists performed histopathologic assessment for grade of thermal injury. Tubal diathermy injury rates were compared between cases and controls. Statistical analysis was undertaken using SPSS version 18. The Mann-Whitney U test compared age distributions; &khgr;2/Fisher tests, the difference between proportions, and &ggr; test, the difference in ordinal variables between the groups. Results A novel tubal thermal index to describe the severity of injury is reported. Lack of fimbrial thermal injury is twice as likely (odds ratio, 2.04; 95% confidence interval, 1.06–3.92) to be associated with detection of occult tubal pathology, whereas isthmic injury does not affect detection rate (P = 0.744). The groups were comparable with respect to age at RRSO (P = 0.531) and the presence of BRCA mutations (P = 0.192). Conclusions This report highlights the potential impact of electrosurgical thermal injury on detection of occult tubal pathology following RRSO. It is important for surgeons to avoid thermal injury to the distal end of the tube.

BACKGROUND:LS women have a 40-60% lifetime risk of endometrial cancer (EC). Most international guidelines recommend screening. However, data on efficacy are limited.PURPOSE:To assess the performance of OHES for EC screening in LS and compare it with transvaginal ultrasound (TVS) alone.METHODS:A prospective observational cohort study of LS women attending a tertiary high-risk familial gynaecological cancer clinic was conducted. LS women opting for EC screening underwent annual OHES and TVS. Histopathological specimens were processed using a strict protocol. Data of women screened between October 2007 and March 2010 were analysed from a bespoke database. Histology was used as the gold standard. Diagnostic accuracy of OHES was compared with TVS using specificity, and positive (PLR) and negative (NLR) likelihood ratios.RESULTS:Forty-one LS women underwent 69 screens (41 prevalent, 28 incident). Four (three prevalent, one incident) women were detected to have EC/atypical endometrial hyperplasia (AEH), five had endometrial polyps and two had endometrial hyperplasia (EH) on OHES. TVS detected two of four EC/AEH. OHES had similar specificity of 89.8% (CI 79.2, 96.2%), but higher PLR 9.8 (CI 4.6, 21) and lower NLR (zero) compared to TVS: specificity 84.75%(CI 73, 92.8%), PLR 3.28 (CI 1.04, 10.35) and NLR 0.59 (CI 0.22, 1.58). No interval cancers occurred over a median follow-up of 22 months. The annual incidence was 3.57% (CI 0.09, 18.35) for EC, 10.71% (CI 2.27, 28.23) for polyps and 21.4% (CI 8.3, 40.1) for any endometrial pathology.CONCLUSIONS:Our findings suggest that in LS, annual OHES is acceptable and has high diagnostic accuracy for EC/AEH screening. Larger international studies are needed for confirmation, given the relatively small numbers of LS women at individual centres. It reinforces the current recommendation that endometrial sampling is crucial when screening these women.

Background The increase in the worldwide incidence of endometrial cancer relates to rising obesity, falling fertility, and the ageing of the population. Transvaginal ultrasound (TVS) is a possible screening test, but there have been no large-scale studies. We report the performance of TVS screening in a large cohort.Methods We did a nested case-control study of postmenopausal women who underwent TVS in the United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) following recruitment between April 17, 2001, and Sept 29, 2005. Endometrial thickness and endometrial abnormalities were recorded, and follow-up, through national registries and a postal questionnaire, documented the diagnosis of endometrial cancer. Our primary outcome measure was endometrial cancer and atypical endometrial hyperplasia (AEH). Performance characteristics of endometrial thickness and abnormalities for detection of endometrial cancer within 1 year of TVS were calculated. Epidemiological variables were used to develop a logistic regression model and assess a screening strategy for women at higher risk. Our study is registered with ClinicalTrials.gov, number NCT00058032, and with the International Standard Randomised Controlled Trial register, number ISRCTN22488978.Findings 48 230 women underwent TVS in the UKCTOCS prevalence screen. 9078 women were ineligible because they had undergone a hysterectomy and 2271 because their endometrial thickness had not been recorded; however, 157 of these women had an endometrial abnormality on TVS and were included in the analysis. Median follow-up was 5.11 years (IQR 4.05-5.95). 136 women with endometrial cancer or AEH within 1 year of TVS were included in our primary analysis. The optimum endometrial thickness cutoff for endometrial cancer or AEH was 5.15 mm, with sensitivity of 80.5% (95% CI 72.7-86.8) and specificity of 86.2% (85.8-86.6). Sensitivity and specificity at a 5 mm or greater cutoff were 80.5% (72.7-86.8) and 85.7% (85.4-86.2); for women with a 5 mm or greater cutoff plus endometrial abnormalities, the sensitivity and specificity were 85.3% (78.2-90.8) and 80.4% (80.0-80.8), respectively. For a cutoff of 10 mm or greater, sensitivity and specificity were 54.1% (45.3-62.8) and 97.2% (97.0-97.4). When our analysis was restricted to the 96 women with endometrial cancer or AEH who reported no symptoms of postmenopausal bleeding at the UKCTOCS scan before diagnosis and had an endometrial thickness measurement available, a cutoff of 5 mm achieved a sensitivity of 77.1% (67.8-84.3) and specificity of 85.8% (85.7-85.9). The logistic regression model identified 25% of the population as at high risk and 39.5% of endometrial cancer or AEH cases were identified within this high risk group. In this high-risk population, a cutoff at 6.75 mm achieved sensitivity of 84.3% (71.4-93.0) and specificity of 89.9% (89.3-90.5).Interpretation Our findings show that TVS screening for endometrial cancer has good sensitivity in postmenopausal women. The burden of diagnostic procedures and false-positive results can be reduced by limiting screening to a higher-risk group. The role of population screening for endometrial cancer remains uncertain, but our findings are of immediate value in the management of increased endometrial thickness in postmenopausal women undergoing pelvic scans for reasons other than vaginal bleeding.

A 13-year-old girl presented with pelvic pain and imaging revealed a large right ovarian cystic mass. Histologic examination showed a malignant myxoid tumor with chicken-wire vasculature characteristic of a myxoid liposarcoma. The morphologic appearances were supported by the presence of the rearrangement of the CHOP gene demonstrated by interphase fluorescent in situ hybridization. There was no evidence that this tumor represented metastatic disease. To the best of our knowledge, primary ovarian myxoid liposarcoma has not been previously reported in the English literature. We present the case and briefly discuss the differential diagnosis.
