European Society of Coloproctology: Guidelines for diagnosis and treatment of cryptoglandular anal fistula.

AIM: The primary aim of the European Society of Coloproctology (ESCP) Guideline Development Group (GDG) was to produce high-quality, evidence-based guidelines for the management of cryptoglandular anal fistula with input from a multidisciplinary group and using transparent, reproducible methodology. METHODS: Previously published methodology in guideline development by the ESCP has been replicated in this project. The guideline development process followed the requirements of the AGREE-S tool kit. Six phases can be identified in the methodology. Phase one sets the scope of the guideline, which addresses the diagnostic and therapeutic management of perianal abscess and cryptoglandular anal fistula in adult patients presenting to secondary care. The target population for this guideline are healthcare practitioners in secondary care and patients interested in understanding the clinical evidence available for various surgical interventions for anal fistula. Phase two involved formulation of the GDG. The GDG consisted of 21 coloproctologists, three research fellows, a radiologist and a methodologist. Stakeholders were chosen for their clinical and academic involvement in the management of anal fistula as well as being representative of the geographical variation among the ESCP membership. Five patients were recruited from patient groups to review the draft guideline. These patients attended two virtual meetings to discuss the evidence and suggest amendments. In phase three, patient/population, intervention, comparison and outcomes questions were formulated by the GDG. The GDG ratified 250 questions and chose 45 for inclusion in the guideline. In phase four, critical and important outcomes were confirmed for inclusion. Important outcomes were pain and wound healing. Critical outcomes were fistula healing, fistula recurrence and incontinence. These outcomes formed part of the inclusion criteria for the literature search. In phase five, a literature search was performed of MEDLINE (Ovid), PubMed, Embase (Ovid) and the Cochrane Database of Systematic Reviews by eight teams of the GDG. Data were extracted and submitted for review by the GDG in a draft guideline. The most recent systematic reviews were prioritized for inclusion. Studies published since the most recent systematic review were included in our analysis by conducting a new meta-analysis using Review manager. In phase six, recommendations were formulated, using grading of recommendations, assessment, development, and evaluations, in three virtual meetings of the GDG. RESULTS: In seven sections covering the diagnostic and therapeutic management of perianal abscess and cryptoglandular anal fistula, there are 42 recommendations. CONCLUSION: This is an up-to-date international guideline on the management of cryptoglandular anal fistula using methodology prescribed by the AGREE enterprise.

Hepatic arterial mapping by multidetector computed tomographic angiography in living donor liver transplantation.

PURPOSE: Our aims were to present the hepatic arterial variations that were detected with computed tomographic angiography (CTA) and confirmed by operation in living liver donors and to emphasize the usefulness of CTA in the assessment of hepatic arterial anatomy. MATERIALS AND METHODS: The donors of 100 patients (46 women and 54 men) who had undergone a living donor liver transplantation in a (blinded) hospital between July 2004 and June 2007 were evaluated. The age of the donors ranged from 18 to 63 years (mean, 39 years). The CTA images obtained by a 16-slice multidetector CT before the transplantation procedure were retrospectively evaluated for arterial variations, and the results were compared with the results of the operation. RESULTS: In 59 donors (59%), classic hepatic arterial anatomy was observed. In the remaining 41 donors (41%), various arterial variations were determined. In 11 of the donors (11%), variations were not compatible with the description of Michel's classification. In all of our patients, CTA findings were confirmed with operational findings. Our complication rate was 1%. Only 1 of the patients who had undergone the transplantation developed hepatic arterial thrombus, and the remaining 99 patients had no arterial complications. CONCLUSIONS: The course of the vascular structures before live donor liver transplantation is essential for planning and success of the operation. Our study showed that multidetector CTA can be used successfully in hepatic artery imaging of liver transplantation donors as a noninvasive method.

[Use of double flaps in high-voltage electrical injury of scalp and calvaria: case report]. / Saçli deri ve kalvaryumun yüksek voltajli elektrik yaralanmasinda çift flep kullanimi: Olgu sunumu.

A 15-year-old boy sustained a high-voltage electrical injury with full-thickness scalp and calvarial bone necrosis in the parieto-occipital region. While necrotic soft tissues were debrided on the fifth day of injury, the devitalized calvaria was preserved. Bilayered coverage of the necrotic bone was achieved by transposition of 'bipedicled pericranial flap' and 'bipedicled scalp flap'. No complication was observed in the postoperative period. A bone resorption area, smaller than the original necrotic bone area, was observed in the long-term follow-ups.

CT and MRI of an unusual intranasal mass: pleomorphic adenoma.

A rare case of pleomorphic adenoma arising from the nasal septum is presented. Computed tomography (CT) and magnetic resonance imaging (MRI) of a 65- year-old woman who presented with right sided nasal obstruction, nasal discharge and epistaxis revealed a well-defined lobular mass occupying the right nasal cavity. Histopathologic examination revealed a pleomorphic adenoma. CT and MRI findings of this rare neoplasm are briefly discussed.
