There seems to be a discrepancy between the information the authors think is collected and what they show. Identifying a bad product, one to avoid, will be impossible if the brand and trade name of the product are not collected with the rest of the operational details. It seems reasonable to assume that the industry funded registries would not collect that information.
Most registries record details of the operation such as urgency of the operation, hernia classification, hernia localization, operating time, operative technique, anesthesia type, mesh type, fixation technique, defect closure, drain utilization and antibiotic prophylaxis (Table 5).”
There is no mesh type category shown in the table. Beside that, how detailed would “mesh type” be? Bard 3D Max? Anatomically shaped mesh? Or just polypropylene? It would be interesting to get in to one of these registries and see the actual information that is collected.
