Outcomes and defect sizeOutcomes and defect size

bull 310 consecutive patients with incisional herniasndash excluding patients with primary hernias and hernias smaller than

5 cm

bull Overall recurrence rate was 6 after an average follow-up of 60 months ndash A multivariate analysis showed that only obesity and defect size

were independent prognostic factorsndash A defect size greater than 10 cm is strongly predictive of

recurrence after laparoscopic incisional hernia repair

bull Conclusionndash Defects larger than 10 cm may require a modified laparoscopic

technique to increase the mesh tissue interface plus

5 cm

bull Overall recurrence rate was 6 after an average follow-up of 60 months ndash A multivariate analysis showed that only obesity and defect size

bull Overall recurrence rate was 6 after an average follow-up of 60 months ndash A multivariate analysis showed that only obesity and defect size

were independent prognostic factorsndash A defect size greater than 10 cm is strongly predictive of

recurrence after laparoscopic incisional hernia repair

Outcomes and defect sizeOutcomes and defect size

bull 310 consecutive patients with incisional herniasndash excluding patients with primary hernias and hernias smaller than

5 cm

bull Overall recurrence rate was 6 after an average follow-up of 60 months ndash A multivariate analysis showed that only obesity and defect size

were independent prognostic factorsndash A defect size greater than 10 cm is strongly predictive of

recurrence after laparoscopic incisional hernia repair

bull Conclusionndash Defects larger than 10 cm may require a modified laparoscopic

technique to increase the mesh tissue interface plus

PATTERNS OF DETERIORATION AND IMPROVEMENT IN ABDOMINAL WALL FUNCTION AFTER VENTRAL INCISIONAL HERNIA REPAIR

RESULTS OF A PROSPECTIVE STUDY

bull abdominal wall strength score (AWSS)ndash validated and reported scoring systemndash physical exam-based measure

bull double leg lowering and trunk raising

ndash significant AWSS change is a change of 2 points or morendash higher scores indicate better abdominal wall function

bull There is a measurable improvement in abdominal wall strength in patients undergoing VIH repairbull (need to use this tool to compare defect closure vs bridge)
