Incidence of ventral hernia surgery after laparoscopic bariatric surgery in Sweden: a registry-based study 2009–2019

1

Bariatric surgery, particularly laparoscopic techniques, is the most effective treatment for morbid obesity but carries a risk of incisional hernias.
2

Trocar site hernias (TSH) can be asymptomatic but may lead to serious complications like bowel incarceration and strangulation.
3

The incidence of TSH varies widely in studies, with estimates ranging from a few percent to 40%, influenced by study design and follow-up duration.
4

The study aimed to assess the incidence of ventral hernias requiring surgical repair after laparoscopic bariatric surgery in Sweden from 2009 to 2019.
5

Data were sourced from the Scandinavian Obesity Surgery Registry and the National Patient Register, ensuring comprehensive coverage of bariatric procedures.
