Intra-abdominal injury identified by CTA in stable blunt polytrauma patients

Background: Patients with multiple injuries are a challenge to evaluate and to exclude abdominal injury, especially those who are intubated and sedated. Ultrasound is a screening tool and peritoneal lavage is unreliable. The aim of the study was to determine the incidence of intra-abdominal injury and describe the subsequent management after CT "panscan" in patients sustaining blunt trauma with injuries both above the thoracic and below the pelvic diaphragm. Methods: In a retrospective analysis anonymised patient data were extracted from a prospective ethics approved database of patients admitted to the level I Trauma Unit at Inkosi Albert Luthuli Central Hospital for the period from April 2007 to March 2011. Blunt polytrauma patients, aged 2 years and older with injuries above the diaphragm and below the pelvic floor were included, provided they were investigated by a full-body trauma Computed Tomography contrast study. Descriptive statistics were employed for all variables of interest, with counts/frequencies and associated percentages being reported. Results: Of 284 patients with injuries above the thoracic and below the pelvic diaphragm, 87 (30.6%) had intra-abdominal injury and 197 (69.4%) had no intra-abdominal injuries. Of those 87 patients, 54 (62.1%) were treated non-operatively and 33 (37.9%) were treated surgically with regard to their abdominal injuries. Twenty (22.9%) patients died, 4 due to intra-abdominal injuries and 16 due to of extra-abdominal injuries. Nine (45%) of the twenty patients who died were treated operatively for intra-abdominal injuries and the remaining 11 (55%) were treated non-operatively.Conclusion: Around thirty percent of patients with injuries above the thoracic and below the pelvic diaphragm had concomitant intra-abdominal injuries. Of those with abdominal injury, just over half required laparotomy. For haemodynamically stable patients CT scanning identified those who require surgical intervention and those who may be managed non-operatively, therefore liberal CT-scanning is advisable for this patient group

Is pelvic floor morphology a predictor of successful pessary retention? Original research and review of the literature

Background. Vaginal pessaries are known to be an effective treatment modality for pelvic organ prolapse (POP). Pessaries form an important part of the physician's armamentarium in the treatment of POP, but currently many of the factors affecting their successful use are poorly understood. Objectives. To determine the association between pessary retention (PR) at 1 year, and functional pelvic floor morphology, i.e. levator hiatal distance and area, and levator avulsion. Methods. This retrospective study reviewed the records of 73 patients with symptomatic POP at a tertiary urogynaecological centre. This multi-ethnic cohort had previously been studied for pelvic-floor morphology, had had 4D transperineal pelvic-floor ultrasound, and had opted for a vaginal pessary as a treatment option. Results. Our population had a mean age of 59.4 (range 32 - 91) years, and mean body mass index of 29.4 (range 20 - 42) kg/m2, with a mean assessment of stage 3 in the Pelvic Organ Prolapse Quantifications System (POP-Q). The level of prolapse was found to be related to PR (p=0.077). We further explored this concept using symmetric measures of association (γ=­0.353), indicating that PR decreases with increasing prolapse severity. PR was also found to be inversely associated with prior pelvic reconstructive surgery (n=63; p=0.055; γ=­0.417). There was a strong correlation that failed, however, to achieve significance by a small margin (p=0.052) between hiatal distance on contraction and PR. Conclusion. This study found an inverse relationship between PR and hiatal distance on contraction, prior pelvic surgery and the severity of prolapse. This was a pilot study with a limited number of participants, and the authors plan a prospective study to further clarify the association between long-term PR and functional pelvic floor morphology
