BACKGROUND Cardiopulmonary resuscitation (CPR) using extracorporeal life support (ECLS) system has been successfully used to support patients with in- and out-of-hospital cardiac arrest (IHCA, OHCA) when conventional measures have failed. The purpose of the current study is to report on our experience with extracorporeal CPR in non-postcardiotomy patients.(More)
Recurrence of secondary hyperparathyroidism (rSHPT) in patients after total parathyroidectomy (TPTX) with autotransplantation (AT) represents a major diagnostic and therapeutic challenge. The aim of this retrospective cohort study was to evaluate rSHPT in patients after TPTX with AT and the subsequent surgical treatment. 112 patients with secondary(More)
The negative influence of conversion from laparoscopic to open colorectal resection on early postoperative morbidity and outcome has been demonstrated several times. In this study, we analyzed the conversion rate and its influence on early postoperative morbidity and short-term oncological outcome following laparoscopic rectal resections. From January 1998(More)
AIMS Major controversies exist regarding the treatment of papillary microcarcinoma of the thyroid (PMC). Prior to 2003 PMC was defined by the WHO as a papillary carcinoma of 1 cm or less in diameter. In 2004 that definition changed, with the new classification requiring that the tumour also must be found incidentally. PATIENTS, METHODS In this study we(More)
CONTEXT Median survival in stage II adrenocortical carcinoma (ACC) differs widely in published series ranging between 23 and more than 60 months. We hypothesized that these results may have been affected by a referral bias because many patients may contact specialized centers only after recurrence. OBJECTIVE The objective of the study was a comparison of(More)
OBJECTIVE Assessing the feasibility and efficiency of interventions using ultrasound (US) volume navigation (V Nav) with real time needle tracking and image fusion with contrast enhanced (ce) CT, MRI or US. METHODS First an in vitro study on a liver phantom with CT data image fusion was performed, involving the puncture of a 10 mm lesion in a depth of 5(More)
The efficacy and feasibility of laparoscopic resection for rectal cancer has been proved, but the results of prospective, randomized studies are not yet available. Here we present a prospective observational study evaluating oncological and clinical outcome after laparoscopic surgery in patients with rectal cancer. Between January 1998 and March 2005, 225(More)
PURPOSE In terms of functional outcome, there is evidence of the superiority of the colonic J-pouch over a straight coloanal anastomosis. Even though the colonic J-pouch was created to restore a neorectal reservoir, manometric data show that the volume of a short colonic J-pouch does not differ from a straight coloanal anastomosis. We speculate that the(More)
OBJECTIVE Single-incision surgery is by now practicable in many fields of surgery, including surgery of the adrenal gland. We report on first experience with laparoscopic transperitoneal and retroperitoneoscopic single-incision adrenalectomy. PATIENTS AND METHODS Between September 2009 and February 2010, eight patients underwent single-incision(More)
BACKGROUND Magnetic resonance imaging (MRI) of the bowel is an increasingly used modality to evaluate patients with Crohn's disease. The Montreal classification of the disease behavior is considered as an excellent prognostic and therapeutic parameter for these patients. In our study, we correlated the behavior assessment performed by a radiologist based on(More)
