Audit of short term outcomes of surgical and medical second trimester termination of pregnancy

<p>Abstract</p> <p>Background</p> <p>As comparisons of modern medical and surgical second trimester termination of pregnancy (TOP) are limited, and the optimum method of termination is still debated, an audit of second trimester TOP was undertaken, with the objective of comparing the outcomes of modern medical and surgical methods.</p> <p>Methods</p> <p>All cases of medical and surgical TOP between the gestations of 13 and 20 weeks from 1st January 2007 to 30th June 2008, among women residing in the local health board district, a tertiary teaching hospital in an urban setting, were identified by a search of ICD-10 procedure codes (surgical terminations) and from a ward database (medical terminations). Retrospective review of case notes was undertaken. A total of 184 cases, 51 medical and 133 surgical TOP, were identified. Frequency data were compared using Chi-squared or Fischer's Exact tests as appropriate and continuous data are presented as mean and standard deviation if normally distributed or median and interquartile range if non-parametric.</p> <p>Results</p> <p>Eighty-one percent of surgical terminations occurred between 13 to 16 weeks gestation, while 74% of medical terminations were performed between 17 to 20 weeks gestation. The earlier surgical TOP occurred in younger women and were more often indicated for maternal mental health. Sixteen percent of medical TOP required surgical delivery of the placenta. Evacuation of retained products was required more often after medical TOP (10%) than after surgical TOP (1%). Other serious complications were rare.</p> <p>Conclusion</p> <p>Both medical and surgical TOP are safe and effective for second trimester termination. Medical TOP tend to be performed at later gestations and are associated with a greater likelihood of manual removal of the placenta and delayed return to theatre for retained products. This case series does not address long term complications.</p

Laparoscopic and open colectomy in high risk patients: a prospective study

Outcome of laparoscopic resection for colorectal cancer in patients with high operative risk

Background. There is general concern that high-risk patients are more susceptible to the adverse effect of pneumoperitoneum and they are often denied laparoscopic surgery. This study investigated the impact of laparoscopic colorectal cancer resection for patients with high operative risk, which was defined as American Society of Anesthesiologist classes 3 and 4. Methods. Three hundred thirty-five consecutive high-risk patients who had colorectal cancer resection by open or laparoscopic surgery were included. The patient and tumor characteristics and operative outcomes were recorded prospectively, and comparison was made between the two groups. Results. Compared to open surgery, patients with laparoscopic resection had a shorter hospital stay (8 [6-12] vs. 6 [4-9] days; P>0.001), less blood loss (200 [100-400] vs. 140 [80-250] mL; P = 0.006), reduced cardiac complication rate (13.2% vs. 3.7%; P = 0.006), overall operative complication rate (36.6% vs. 21.3%; P = 0.006), and a trend toward a lower mortality rate (4.4% vs. 0.9%; P = 0.083). There was no difference in 3-year overall and disease-free survival between two groups. Operative blood loss (P = 0.035; odds ratio = 2.69; 95% confidence interval, 1.00-6.78) and open surgery (P = 0.007; odds ratio = 2.31; 95% confidence interval, 1.26-4.23) were independent factors for occurrence of complication. Conclusions. Laparoscopic colorectal cancer resection is associated with more favorable short-term results and should be recommended as the preferred treatment option for high-risk patients. © Society of Surgical Oncology 2011.link_to_subscribed_fulltex

The importance of gestational age in first trimester, maternal urine MALDI-Tof MS screening tests for Down Syndrome

Background: The proposal that MALDI-ToF mass spectrometry could be used as a direct, rapid and affordable diagnostic tool in clinical laboratory medicine has moved from a theoretical possibility to a reality for Microbiology. Several studies have proposed the application of this technology in obstetric and gynaecological evaluation of patients. In particular, we have proposed that the adoption of MALDI-ToF mass spectrometry in examination of maternal pregnancy urine samples for the detection of Downs syndrome. Methods: A retrospective collection of 20 Down Syndrome and 100 non-aneuploid pregnancy urines at 12 to 14 weeks gestation, collected in 2007-2008 from high risk pregnancy cohorts, were examined by MALDI-ToF mass spectrometry in the mass/charge range between 1000 and 100000 m/z. Normalisation of spectral data was defined using mass bins of 100 m/z expressed as a percentage of the total ion count of the mass spectra from 2000 to 11000 m/z. Of the ninety 100 m/z bins, forty-six were identified as m/z bins at which statistically significant differences in spectra occurred between Downs and control/non-aneuploid samples. Based on the differences and variance, for values at these bins, weighted scores of the probability of being Downs were assigned. Comparative algorithms consisting of various mass bins were tested for ability to distinguish Down syndrome from non-aneuploid pregnancy. Results: Although various algorithms could distinguish Downs from non-aneuploid controls, it was found that gestational age was a confounding factor and that if separated into gestational age matched cohorts the ability to distinguish the groups improved dramatically e.g. whilst a 19 bins algorithm separated 100% of Downs from non-aneuploid pregnancies for a 9% false positive rate in the mixed gestational ages group; a two bin algorithm distinguished 100% of Downs for a 6% false positive rate for the 12 weeks gestational age pregnancies. Conclusion: Normalised MALDI-ToF mass spectra, at 2000 to 11000 m/z, of maternal urine gives rise to gestational age specific screening tests algorithms for Downs&rsquo;s syndrome
