Laparoscopic Measuring Device Usability Study

In June of 2016, SAGES (Society of American Gastrointestinal and Endoscopic Surgeons) issued a recommendation stating that:

"Surgeons should measure and document the size of the hernia defect they are repairing. The total area encompassing all the defects should be measured, and surgeons should be familiar with internal and external measurement techniques for all hernia locations, as well as how to avoid common measurement errors."

An incorrect mesh size can have detrimental consequences to the effectiveness of the mesh. According to the SAGES recommendation:

"Overestimating the defect size will result in the choice of a larger prosthetic size, which may be more difficult to handle and may have more laxity, allowing it to bulge into the defect more than if it was placed taut. The difficulty in prosthetic handling may also lead to errors in fixation, and the prosthetic can more easily sway between fixation points, due to the larger dimensions."

While a smaller mesh size can also be problematic:
