Reduced Need for In-hospital Care After Sleeve Gastrectomy: a Single Center Observational Study.

Setting: Private clinic, Stockholm, and nation-wide in-hospital care, Sweden.

Objectives: The use of sleeve gastrectomy (SG) for treatment of morbid obesity has increased worldwide, but information about long-term outcome is still limited. Our objective was to evaluate the need for additional in-hospital care after SG for obesity (body mass index [BMI] > 30) in 862 patients, all operated at a single center.

Adding 11C-acetate to 18F-FDG at PET Examination Has an Incremental Value in the Diagnosis of Hepatocellular Carcinoma.

Objective: The sensitivity of FDG at PET examination of Hepatocellular Carcinoma (HCC) is restricted. In a few studies, all done in Oriental patients, PET-examination with (11)C-acetate has shown a higher accuracy than with FDG. In the current study, the uptake of (11)C-acetate has been compared with the uptake of FDG in the primary HCC in a cohort of Occidental patients.

International Sleeve Gastrectomy Expert Panel Consensus Statement: best practice guidelines based on experience of >12,000 cases.

Background: Laparoscopic sleeve gastrectomy (LSG) is an emerging surgical approach, but 1 that has seen a surge in popularity because of its perceived technical simplicity, feasibility, and good outcomes. An international expert panel was convened in Coral Gables, Florida on March 25 and 26, 2011, with the purpose of providing best practice guidelines through consensus regarding the performance of LSG. The panel comprised 24 centers and represented 11 countries, spanning all major regions of the world and all 6 populated continents, with a collective experience of >12,000 cases.

Acceptance and commitment therapy for bariatric surgery patients, a pilot RCT.

Bariatric surgery (BS) is rated as the best evidence based treatment for obesity with regard to weight loss and maintenance of weight loss evaluated to date. Although BS interventions are effective, 20-30% of BS patients start to regain weight within 24 months. Emotional eating is a behavior pattern which has been found to predict poor outcome.

Initial results with sleeve gastrectomy for patients with class I obesity (BMI 30-35 kg/m2).

Background: To investigate the role of sleeve gastrectomy for patients with class I obesity (body mass index 30-35 kg/m(2)) at a private hospital with self-paying patients. Randomized trials have shown a benefit for bariatric surgery compared with conservative treatment in patients with class I obesity. Sleeve gastrectomy is a relatively new method that has not been previously evaluated in this group of patients.

Laparoscopic left lobe liver resection in a porcine model: a study of the efficacy and safety of different surgical techniques.

Introduction: Laparoscopic liver surgery is evolving and the best technique for dividing the liver parenchyma is currently under debate. The aim of this study was to study different techniques during a full laparoscopic lobe resection, and determine the efficacy and risks of bleeding and gas embolism.

Methods: Sixteen pigs were randomized to two groups: group US underwent an operation with Ultracision shears (AutoSonix) and ultrasonic dissector (CUSA) and group VS with a vessel sealing system (Ligasure) and ultrasonic dissector.

Does chemotherapy prior to liver resection increase the potential for cure in patients with metastatic colorectal cancer? A report from the European Colorectal Metastases Treatment Group.

Liver resection offers the only chance of cure for patients with advanced colorectal cancer (CRC). Typically, the 5-year survival rates following liver resection range from 25% to 40%. Unfortunately, approximately 85% of patients with stage IV CRC have liver disease which is considered unresectable at presentation.

Proficiency-based virtual reality training significantly reduces the error rate for residents during their first 10 laparoscopic cholecystectomies.

Background: Virtual reality (VR) training has been shown previously to improve intraoperative performance during part of a laparoscopic cholecystectomy. The aim of this study was to assess the effect of proficiency-based VR training on the outcome of the first 10 entire cholecystectomies performed by novices.

Methods: Thirteen laparoscopically inexperienced residents were randomized to either (1) VR training until a predefined expert level of performance was reached, or (2) the control group.

Is the learning curve for laparoscopic fundoplication determined by the teacher or the pupil?

Background: For all surgical procedures, a surgeons' learning curve can be anticipated during which complication rates are increased. The aims of this study were to evaluate individual learning curves for a group of surgeons performing laparoscopic fundoplication and to evaluate if the Procedicus MIST-simulator (Mentice Inc., Göteborg, Sweden) accurately predicts surgical performance.
