Immediate postoperative pain control is an important, and at times, difficult aspect in laparoscopic ventral hernia repair. In this study we examined whether placement of larger mesh, with a greater number of tacks, is associated with a greater usage of pain medication after surgery.
A prospective database of laparoscopic ventral hernia repairs performed at a single institution was retrospectively reviewed. Mesh fixation was accomplished with circumferential spiral tacks (ProTack, Covidien, North Haven, CT) and 4-6 trans-fascial sutures. Mesh sizes were recorded in each case, and mesh perimeters were calculated as a surrogate measure of the number of tacks placed. Narcotic usage in the recovery room was documented and morphine equivalents calculated.
Between September 2007 and September 2011, 94 patients underwent a laparoscopic ventral hernia repair with Parietex composite mesh (Covidien, North Haven, CT) (52 incisional, 39 umbilical, 2 epigastric, 1 spigellian). The average mesh perimeter was 47.6 ± 20.0 cm (range 21.98-110 cm). The average narcotic use in the recovery room corresponded to a morphine dose of 6.91 ± 7.29 mg. there was no correlation between mesh perimeter and morphine dose (correlation coefficient = -0.09). However, when the cohort was divided into small mesh (<50 cm perimeter) and large mesh (>50 cm perimeter), there was a significant difference in morphine usage. Patients with small mesh required significantly more morphine compared to those with large mesh (8.07 mg vs. 5.22 mg, p=0.03).
The number of tacks used to secure the mesh in a laparoscopic ventral hernia repair does not significantly influence immediate postoperative narcotic pain medication requirements. Pain medication requirements are not decreased when smaller mesh and fewer tacks are used.
