Transduodenal resection of a large papillary tumor by means of intraoperative cholangioscopy.

Introduction: Papillary adenomas are very rare benign tumors of the gastrointestinal tract. If manageable, purely endoscopic resection is favored. As an alternative, surgical resection via ampullectomy or pancreaticoduodenectomy can be performed.

Operative R0 resection of diffuse large B-cell lymphoma of the pelvis: a case report.

Background: Diffuse large B-cell lymphoma is the most common subtype of non-Hodgkin lymphoma with or without involvement of extranodal sites. Rituximab in combination with cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP) therapy represents the current standard therapy, achieving a rather dissatisfying outcome in approximately 30-40% of all cases.

Case Presentation: We present the case of a 43-year-old Austrian woman with an incidentally detected large pelvic mass which was diagnosed as diffuse large B-cell lymphoma.

Do we follow evidence-based medicine recommendations during inguinal hernia surgery? Results of a survey covering 2441 hernia repairs in 2007.

Background: We conducted a survey to determine whether hernia surgeons follow evidence-based medicine (EBM) criteria in their daily routine.

Methods: All chiefs of general surgery in Styria (Austria) received a short, simple, two-page, 10-item questionnaire.

Results: We analyzed completed surveys from 15 departments reporting 2441 hernia repairs with a mean patient age of 57.

Prospective study comparing standard and robotically assisted laparoscopic cholecystectomy.

Background And Aims: Laparoscopic surgery has become the treatment of choice for cholecystectomy. Many studies showed that while this approach benefits the patient, the surgeon faces such distinct disadvantages as a poor ergonomic situation and limited degrees of freedom with limited motion as a consequence. Robots have the potential to overcome these problems.

Accuracy of preoperative routine MRI for hepatic lesion detection.

Background: The outcome of liver resections depends on complete removal of all detectable foci. Our aim was to determine the value of preoperative routine magnetic resonance imaging (MRI) for complete detection of hepatic lesions.

Methods: We compared 271 lesions seen on MRI in 182 patients to intraoperative findings (including intraoperative ultrasonography) and histology.

Surgical therapy options in polycystic liver disease.

Introduction: Polycystic liver disease (PLD) is a rare affliction frequently observed in association with polycystic kidney disease. Only symptomatic patients require treatment, which can be conservative or surgical, i.e.

Minimally invasive management of dysontogenetic hepatic cysts.

Background: Liver cysts occur with a prevalence of 4%-7% in the general population. Laparoscopic surgery is effective for solitary cysts and in selected patients with polycystic liver disease (PLD). We present our experience in the laparoscopic management of dysontogenetic cysts.

[Endoscopic palliation of malignant gastric outlet obstruction by self-expanding metal stents].

Introduction: Malignant gastric outlet stenosis is caused by tumour obstruction and restricts the oral intake of food, resulting in a seriously reduced quality of life. Endoscopic implantation of self expanding metal stents (SEMS) can clear stenosis in the GI-tract and reestablish and preserve the passage in the GI-tract.

Patients And Methods: Between October 2001 and April 2003 seven patients with malignant gastric outlet stenosis have been treated by the implantation of SEMS.

Is intraoperative ultrasonography during partial hepatectomy still necessary in the age of magnetic resonance imaging?

Background/aims: The aim of our study was to determine if intraoperative ultrasonography is still necessary in the time of magnetic resonance imaging.

Methodology: Our prospective study comprised 122 patients (82% with malignant tumors) undergoing partial hepatectomy with preoperative magnetic resonance imaging, done at the same institution using a standardized liver protocol as well as intraoperative ultrasonography performed in a systematic fashion.

Results: Seventeen additional malignant lesions in 16/122 patients (13.
