Mini- or Less-Open Sublay Operation (MILOS) - a New Minimally Invasive Technique for the Extraperitoneal Repair of Incisional Hernias

Prospective non-randomized observational register study of all elective symptomatic incisional hernias operated on in the Reference Hernia Center of Gross Sand Hospital between 1 January 2010 and 30 September 2015 using the novel endoscopic assisted Mini- or Less-Open Sublay technique. The novel MILOS-technique allows the minimal invasive implantation of large extraperitoneal meshes for the treatment of primary and secondary incisional hernias.The data of all patients were prospectively documented in the German Hernia Registry "Herniamed". Data privacy protection was strictly implemented according to German federal law. All patients were informed in detail about the new surgical technique, other treatment options, prospective register study with one year questionnaire follow-up, data documentation. All patients gave written consent.

A propensity score matching of all patients of the MILOS-cohort of Gross Sand Hospital with patients with comparable incisional hernias who were operated on using the laparoscopic intraperitoneal onlay mesh (IPOM) technique or open sublay technique in other institutions participating in the German Hernia Database "Herniated" was performed.
