Fistula development after anal abscess drainage-a multicentre retrospective cohort study.

Purpose: Anal abscesses are common and, despite correct treatment with surgical drainage, carry the risk of developing fistulas. Studies identifying risk factors for the development of anal fistulas are sparse. This study aimed to identify the risk factors for anal fistulas after anal abscess surgery.

This case report describes a uterine rupture initially misinterpreted as acute appendicitis. Uterine rupture is a rare but serious obstetric complication, whereas acute appendicitis is one of the most common causes of abdominal pain. The patient gave vaginal birth after previously having had a caesarean delivery.

[Treatment of perianal fistulas with mesenchymal stem cells].

Treatment of perianal fistulas are challenged by insufficient healing and a high rate of relapse. Existing sphincter-sparing procedures have healing rates of around 50%. Treatment with mesenchymal stem cells of both autologous and allogenic origin and freshly collected autologous adipose tissue show both promising healing rates and few complications and may be offered to patients with complicated fistulas not suited for other treatment modalities.

[Cryptoglandular anal fistulas].

Cryptoglandular anal fistulas (AF) cause recurrent anal abscesses and patients risk multiple surgeries due to low healing rates of sphincter-saving procedures. Knowledge of anal anatomy and imaging with MRI or endoanal sonography is crucial to classify AF as simple or complex depending on risk of anal incontinence after fistulotomy as summarised in this review. Fistulotomy has healing rates of > 90%, risks incontinence, and the procedure is reserved for simple fistulas.

Fistula Laser Closure (FiLaC™) for fistula-in-ano-yet another technique with 50% healing rates?

Purpose: Treatment of ano-cutaneous fistulas remains a therapeutic challenge. Fistula Laser Closure (FiLaC™) is a relatively new technique for the treatment of ano-cutaneous fistulas. This study aimed to determine the success rate of fistula closure using FiLaC™.

[Treatment of anal abscesses].

Anal abscesses are well-known conditions worldwide. The golden standard of acute treatment is incision and drainage. Knowledge of the anatomy of the anal area and the abscess involvement of perianal spaces is crucial in order to perform safe and correct surgical treatment as summarised in this review.

Treatment of chronic anal fissure: a feasibility study on Levorag® Emulgel versus Diltiazem gel 2.

Purpose: To compare the standard treatment, diltiazem gel 2%, with Levorag® Emulgel for chronic anal fissures.

Methods: This was a single-blinded, randomised, controlled, clinical trial with a non-inferiority design. Patients with a chronic anal fissure were randomised to treatment with diltiazem or Levorag® Emulgel twice daily for 8 weeks.

Mortality after abdominal emergency surgery in nonagenarians.

Purpose: To search the pattern of diagnoses in nonagenarians undergoing emergency abdominal surgery between January 2009 and December 2013 in two hospitals. To test the hypothesis that pre-hospital functional status is an effective criterion for predicting postoperative mortality in nonagenarians after emergency abdominal surgery.

Methods: The study is an observational study on 157 patients.

Renal function after elective total hip replacement.

Background and purpose - Acute kidney injury (AKI) is associated with increased short-term and long-term mortality in intensive care populations and in several surgical specialties, but there are very few data concerning orthopedic populations. We have studied the incidence of AKI and the prevalence of chronic kidney disease (CKD) in an elective population of orthopedic patients undergoing primary total hip replacement, hypothesizing that chronic kidney disease predisposes to AKI. Patients and methods - This was a single-center, population-based, retrospective, registry-based cohort study involving all primary elective total hip replacements performed from January 2003 through December 2012.

Medication errors detected in non-traditional databases: types of errors in methotrexate dosing as listed in four different Danish registers.

Aims: We have looked for medication errors involving the use of low-dose methotrexate, by extracting information from Danish sources other than traditional pharmacovigilance databases. We used the data to establish the relative frequencies of different types of errors.

Methods: We searched four databases for cases involving low-dose methotrexate between 1999 and 2011: the Danish Patient Safety Databases (DPSD), controlled by the Danish National Agency for Patients' Rights and Complaints, the Patient Compensation Association (PCA), the Danish Poison and Information Centre (DPIC), and the online database of the Department for Patient Complaints (DPC).
