Impact of the mesh fixation technique on operation time in laparoscopic repair of ventral hernias

Background Fixation of the prosthesis is one of the critical components of laparoscopic repair of ventral and incisional hernia (LRVIH). The impact of the fixation technique used on operative time has never been analyzed. We compared the duration of the operation according to the fixation technique used in a series of 138 patients with primary umbilical hernia. Methods All patients underwent a straightforward repair by using completely standardized techniques. One hundred and seven patients had mesh fixation with a single crown of tackers (ProTack (R), TycoUSS, Norwalk, CT) and eight transabdominal sutures (TAS). Thirty-one patients had mesh fixation with a double crown of tackers (DC) without TAS. Results There were no significant differences in age, sex, hospital stay, and morbidity between the two groups. Mean operating time for the technique with TAS was 50.6 min compared to 41.4 min for the DC technique. The mean difference in operating time was 9.2 min. This difference was significant (P = 0.002). During a mean follow-up of 26.4 months, there were no recurrences in the entire series. Conclusions The difference in operative times between the two operative techniques can be entirely accounted to the difference in the time needed for insertion of eight TAS as compared to the time needed for application of an inner crown of tackers. This strongly indicates that insertion of every single TAS prolongs LRVIH for approximately 1 min. As long as no significant differences between the two fixation techniques are demonstrated on issues of recurrence, complications, and postoperative pain, the time difference we have measured might be an argument in favor of the DC technique, especially when mesh fixation would require a large number of TAS.
