Magnet design for a low-emittance storage ring.

The MAX IV 3 GeV storage ring, currently under construction, pursues the goal of low electron beam emittance by using a multi-bend achromat magnet lattice, which is realised by having several consecutive magnet elements precision-machined out of a common solid iron block, 2.3-3.4 m long.

Bowel obstruction after laparoscopic and open colon resection for cancer: results of 5 years of follow-up in a randomized trial.

Background: Postoperative bowel obstruction caused by intra-abdominal adhesions occurs after all types of abdominal surgery. It has been suggested that the laparoscopic technique should reduce the risk for adhesion formation and thus for postoperative bowel obstruction. This study was designed to compare the incidence of bowel obstruction in a randomized trial where laparoscopic and open resection for colon cancer was compared.

LAPPRO: a prospective multicentre comparative study of robot-assisted laparoscopic and retropubic radical prostatectomy for prostate cancer.

Objective: This study describes the study design and procedures for a prospective, non-randomized trial comparing open retropubic and robot-assisted laparoscopic radical prostatectomy regarding functional and oncological outcomes.

Material And Methods: The aim was to achieve a detailed prospective registration of symptoms experienced by patients using validated questionnaires in addition to documentation of surgical details, clinical examinations, medical facts and resource use. Four patient questionnaires and six case-report forms were especially designed to collect data before, during and after surgery with a follow-up time of 2 years.

Analysis of patient selection and external validity in the Swedish contribution to the COLOR trial.

Objective: The colon cancer laparoscopic or open resection (COLOR) trial is an international, randomised controlled trial comparing outcomes of open and laparoscopic surgery for colon cancer. The main purpose of this study was to determine representability by comparing included and nonincluded patients in the participating Swedish centres.

Design: At eight centres, which included 391 of the 422 Swedish patients, a local database search was performed to identify retrospectively all patients (n = 2,384) who underwent surgery for colon cancer during the inclusion period, and data was retrieved from medical records.

Outpatient versus inpatient laparoscopic cholecystectomy: a prospective randomized study of symptom occurrence, symptom distress and general state of health during the first post-operative week.

Background: Few randomized clinical trials focus on patients' symptoms of the first post-operative week following outpatient (OPS) versus inpatient (IPS) laparoscopic cholecystectomy (LC). The objective was to compare these treatment modalities with regard to patients' perceptions of pain and other post-operative symptoms, amount of distress, level of anxiety and general state of health during the first post-operative week.

Methods: One hundred patients were randomized.
