OBJECTIVE To assess the impact of postoperative complications on full in-hospital costs per case. BACKGROUND Rising expenses for complex medical procedures combined with constrained resources represent a major challenge. The severity of postoperative complications reflects surgical outcomes. The magnitude of the cost created by negative outcomes is(More)
BACKGROUND Although laparoscopy is associated with reduced hospital stay, early recovery, and decreased morbidity compared with open surgery, it is not well established for the treatment of small bowel obstruction (SBO). METHODS This study analyzed a prospective nationwide database of the Swiss Association of Laparoscopic and Thoracoscopic Surgery. (More)
BACKGROUND Surgical residents often use a laparoscopic camera in minimally invasive surgery for the first time in the operating room (OR) with no previous education or experience. Computer-based simulator training is increasingly used in residency programs. However, no randomized controlled study has compared the effect of simulator-based versus the(More)
BACKGROUND This investigation assessed the long-term outcome of patients with gastric banding implanted more than 10 years ago. METHODS A total of 73 patients undergoing laparoscopic gastric banding between 1997 and 2003 were identified. Patients who had their band removed were converted to a laparoscopic gastric bypass procedure. RESULTS The mean(More)
D-dimers may be elevated after surgery. However, the kinetics of postoperative D-dimers remains unknown hampering the use of D-dimer testing in surgical patients with suspected venous thromboembolism. D-dimer levels were prospectively measured in 154 patients after general surgery at predefined time points (kinetics were determined in an initial cohort of(More)
BACKGROUND Accurate knowledge of tumour presence and location is essential to treat neuroendocrine tumours (NETs). Standard imaging has been hampered by low sensitivity and lack of spatial resolution. This study assessed prospectively the diagnostic value and impact of combined 6-[18F]fluorodihydroxyphenylalanine positron emission tomography-computed(More)
In the isolated rat stomach perfused via the vasculature in situ under constant pressure bolus injections of platelet-activating factor (PAF, 3, 16, or 50 ng) induced dose-dependent, long-lasting reductions of flow rates and simultaneously significant increases in the release of cysteinyl-leukotrienes (cys-LT), thromboxane (TX) B2 and 6-keto-prostaglandin(More)
BACKGROUND Obese patients are generally believed to be at a higher risk for surgery than those who are not obese, although convincing data are lacking. METHODS We prospectively investigated a cohort of 6336 patients undergoing general elective surgery at our institution to assess whether obesity affects the outcome of surgery. Exclusion criteria were(More)
BACKGROUND In up to 4% of laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures, anastomotic leaks occur. Early detection of gastrointestinal leakage is important for successful treatment. Consequently, many centers advocate routine postoperative upper gastrointestinal (UGI) series. The aim of this study was to determine the utility of this practice(More)
The surgical treatment for perforated peptic ulcers can be safely performed laparoscopically. The aim of the study was to define simple predictive factors for conversion and septic complications. This retrospective case–control study analyzed patients treated with either laparoscopic surgery or laparotomy for perforated peptic ulcers. A total of 71 patients(More)
