We have demonstrated that open cholecystectomy, the most traumatic of cholecystectomy methods used today, has been preferred for our most vulnerable patients, either as primary procedure or as conversion from laparoscopic cholecystectomy.
Patients in group A did not have previous shunt before insertion of stent (stent as primary procedure) while group B patients already had shunt(s) in situ (stent as secondary procedure).
3– 8 Corneal prostheses are available, but they remain mainly for end-stage disease and even if implanted as primary procedure they often are accompanied by vision-threatening complications, 1, 9 leaving an unmet need for a de novo solution for high-risk patients.
The following variables were considered as confounders: age at primary procedure (in categories 10 49, 50 59, 60 69, 70 79, and 80+), sex, type of fixation (in the categories cemented, uncemented, or hybrid) and comorbidity measured with the Charlson comorbidity index.
A microsurgical technique as the primary procedure, such as an isolated laminotomy or microdiscectomy.
Data were extracted from the DNPR on all record numbers containing a procedure code(s) for meniscal surgery (KNGD and all sub-codes) as the primary procedure or as part of other surgery in the twelve-year period 2000 2011.
Data were retrieved on all patients who underwent arthroscopic meniscus surgery (KNGD and all subcodes) either as a primary procedure or as part of other surgery in the years 2000 to 2011 (including both years).
Patients will be excluded from the study if they meet any of the following criteria: A microsurgical technique as the primary procedure, such as an isolated laminotomy or microdiscectomy.
The main indication is instability with a glenoid bone defect, but it is increasingly used as a revision procedure following previous surgery and as the primary procedure in cases with weak anterior structures (Blomquist et al. 2012).
