The aim of this study was to assess the feasibility and safety laparoscopic surgery for cure colorectal cancer with emphasis on oncologic follow-up in particular.A performed patients treated by laparoscopy five German centers between May 1991 September 1997. Surgical pathologic data were recorded an anonymous registry database analyzed type resection. Standard procedures sigmoid or left colectomy, anterior resection, abdominoperineal right hemicolectomy. Follow-up information included...

Treatment of high anal fistulas may be associated with a risk continence disorders. Beside traditional procedure flap-reconstruction the occlusion fistula tract using fistula-plugs offers new sphincter-saving treatment option. In this study for first time results from Germany are described.40 patients (30 male, 10 female, age 51 ± 12 years) underwent closure trans-sphincteric (n = 28) or supra-sphincteric 12) Gore BioA Fistula Plug(®) in three surgical departments.

The OTSC Proctology is a surgical device for anorectal fistula closure. It consists of super-elastic nitinol clip, which placed (with the aid transanal applicator) on internal opening to achieve healing track. A prospective, two-centre clinical pilot study was undertaken assess efficacy and safety in patients with complex high fistula.In primary track debrided using special brush clip applied opening. After 6 months postoperative course were assessed.Twenty cryptoglandular (14...

The effectiveness of modern perioperative treatment concepts has been demonstrated in several studies and meta-analyses. Despite good evidence, limited implementation the fast track (FT) concept is still a widespread concern. To assess status quo Austrian German hospitals, survey on FT measures was conducted among members Society General Visceralsurgery (DGAV), Coloproctology (DGK) Surgery (OEGCH) to analyze where there potential for improvement.Twenty questions care colorectal surgery...

'Fast-track' rehabilitation has been shown to accelerate recovery, reduce general morbidity and decrease hospital stay after elective colonic surgery. Despite this evidence, there is no information on the acceptance utilization of these concepts among entirety Austrian German surgeons. In 2006, a questionnaire concerning perioperative routines in elective, open resection was sent chief surgeons 1270 120 surgical centres.

Liver vessel segmentation in magnetic resonance imaging data is important for the computational analysis of vascular remodelling, associated with a wide spectrum diffuse liver diseases. Existing approaches rely on contrast enhanced data, but necessary dedicated sequences are not uniformly acquired. Images without enhancement acquired more frequently, challenging, and requires large-scale annotated data. We propose multi-task learning framework to segment vessels MRI contrast. It exploits...
