Difficult prenatal diagnosis: fetal coarctation.

The prenatal diagnosis of fetal coarctation is still challenging. It is mainly suspected by ventricular disproportion (smaller left ventricle than right ventricle). The sensitivity of ventricular discrepancy is however moderate for the diagnosis of coarctation and there is a high false positive rate. Prenatal diagnosis of coarctation is important because the delivery can be arranged in a centre with a pediatric cardiac intensive careand this reduces postnatal complications and longterm morbidity. For many years the prenatal diagnosis of coarctation has been investigated to improve specificity and sensitivity by several of measurements. This article reviews all relevant articles from 2000 until 2011 searching pubmed and the reference list of interesting articles. An overview of specific measurements and techniques that can improve the diagnosis of coarctation has been made, such as the isthmus diameter, ductal diameter, isthmus/ductal ratio, z-scores derived from measurements of the distal aortic isthmus and arterial duct, the presence of a shelf andisthmal flow disturbance. Also 3-dimensional (3D) and 4-dimensional (4D) imaging with or without STIC has been -suggested to be used as newer techniques to improve diagnosis of coarctation in fetal life. Although more methods regarding prenatal diagnosis of coarctationare being investigated, the ultrasound specialist remains challenged to correctly diagnose this cardiac anomaly in prenatal life.

Clinical outcome after CO2 laser laparoscopic radical excision of endometriosis with colorectal wall invasion combined with laparoscopic segmental bowel resection and reanastomosis.

BACKGROUND: Laparoscopic segmental bowel resection and reanastomosis for endometriosis with colorectal wall invasion can be associated with high complication rates. This study was performed to test the hypothesis that this high complication rate can be prevented and combined with a good clinical outcome, following a multidisciplinary surgical approach. METHODS: A retrospective cohort study of all patients with deep endometriosis and colorectal invasion treated by CO2 laser laparoscopic radical excision between September 2004 and September 2006 (n = 45) to document the clinical outcome: complications, recurrence and fertility (life table analysis), pain, quality of life (QOL) and sexual function. RESULTS: No immediate major post-operative complications requiring surgical reintervention were recorded. Gynaecological pain (P < 0.0001), sexual function (P < 0.03) and QOL (P< 0.0001), improved significantly after a median follow-up period of 27 (range: 16-40) months. Although five patients (11%) had a surgical reintervention, histologically proven recurrent endometriosis was observed in only two (4%), with a cumulative endometriosis recurrence rate of 2.2 and 4.4% after 1 and 3 years, respectively. Thirteen of 28 patients who wanted to become pregnant conceived after surgery. One patient delivered twice. These 14 pregnancies were achieved spontaneously (n = 9) or after IVF (n = 5). The cumulative pregnancy rate was 47% after 3 years. CONCLUSION: Pain, sexual function and QOL improved significantly and were associated with a good fertility rate and a low complication and recurrence rate after a CO2 laser laparoscopic radical excision of endometriosis with colorectal wall invasion combined with laparoscopic segmental bowel resection and reanastomosis.
