[The Scandinavian Obesity Surgery Registry - register for quality and research].

The Scandinavian Obesity Surgery Registry (Soreg) was initiated in 2007 in order to track the quality of bariatric surgery in Sweden during a period of rapid expansion. The main focus of Soreg is quality control and a base for research. All surgical units that perform bariatric surgery in Sweden report to Soreg, and to date about 93 000 patients are included in Soreg.

Impact of surgical technique on gastroesophageal reflux disease after laparoscopic sleeve gastrectomy: a nationwide observational study.

Background: Laparoscopic sleeve gastrectomy (LSG) has gained increasing popularity worldwide, yet concerns persist regarding the development of gastroesophageal reflux disease (GERD) postoperatively.

Objectives: This study aimed to evaluate the influence of technical aspects of LSG, specifically bougie size and distance from the pylorus to resection line edge, on the risk of developing symptomatic GERD within 2years following surgery.

Setting: Data from the Scandinavian Obesity Surgery Registry (SOReg) and the National Prescribed Drug Register were utilized for this analysis.

Anemia in patients ten years after bariatric surgery.

Background: More than 10% of the global population has a BMI above 35. Bariatric surgery is an efficient way to treat this condition. Unfortunately, there is a risk of nutritional deficiencies.

A national long-read sequencing study on chromosomal rearrangements uncovers hidden complexities.

Clinical genetic laboratories often require a comprehensive analysis of chromosomal rearrangements/structural variants (SVs), from large events like translocations and inversions to supernumerary ring/marker chromosomes and small deletions or duplications. Understanding the complexity of these events and their clinical consequences requires pinpointing breakpoint junctions and resolving the derivative chromosome structure. This task often surpasses the capabilities of short-read sequencing technologies.
