Purpose. Operative efficiency improvements for laparoscopic ventral hernia repair (LVHR) have focused on reducing operative time while maintaining overall repair efficacy. Our objective was to evaluate procedure time and positioning accuracy of an inflatable mesh positioning device (Echo PS Positioning System), as compared to a standard transfascial suture technique, using a porcine model of simulated LVHR. Methods. The study population consisted of seventeen general surgeons (n=17) that performed simulated LVHR on seventeen (n=17) female Yorkshire pigs using two implantation techniques: (1) Ventralight ST Mesh + Echo PS Positioning System (Echo PS) and (2) Ventralight ST Mesh + transfascial sutures (TSs). Procedure time and mesh centering accuracy overtop of a simulated surgical defect were evaluated. Results. Echo PS demonstrated a 38.9% reduction in the overall procedure time, as compared to TS. During mesh preparation and positioning, Echo PS demonstrated a 60.5% reduction in procedure time (P<0.0001). Although a trend toward improved centering accuracy was observed for Echo PS (16.2%), this was not significantly different than TS. Conclusions. Echo PS demonstrated a significant reduction in overall simulated LVHR procedure time, particularly during mesh preparation/positioning. These operative time savings may translate into reduced operating room costs and improved surgeon/operating room efficiency.

The Mean

Introduction The Ethicon™ laparoscopic inguinal groin hernia training (LIGHT) course is an educational course based on three days of teaching on laparoscopic hernia surgery. The first day involves didactic lectures with tutorials. The second day involves practical cadaveric procedures in laparoscopic hernia surgery. The third day involves direct supervision by a consultant surgeon during laparoscopic hernia surgery on a real patient. We reviewed our outcomes for procedures performed on real patients on the final day of the course for early complications and outcomes. Methods A retrospective study was undertaken of patients who had laparoscopic hernia surgery as part of the LIGHT course from 2013 to 2015. A matched control cohort of patients who had elective laparoscopic hernia surgery over the study period was identified. These patients had their surgery performed by the same consultant general surgeons involved in delivering the course. All patients were followed up at 6 weeks postoperatively. Results A total of 60 patients had a laparoscopic inguinal hernia repair and 23 patients had a laparoscopic ventral hernia repair during the course. The mean operative time for laparoscopic inguinal hernia repair was 48 minutes for trainees (range 22–90 minutes) and 35 minutes for consultant surgeons (range 18–80 minutes). There were no intraoperative injuries or returns to theatre in either group. All the patients operated on during the course were successfully performed as daycase procedures. The mean operative time for laparoscopic ventral hernia repair was 64 minutes for trainees (range 40–120 minutes) and 51 minutes for consultant surgeons (range 30–130 minutes). Conclusions The outcomes of patients operated on during the LIGHT course are comparable to procedures performed by a consultant. Supervised operating by trainees is a safe and effective educational model in hernia surgery.

Abstract Background Repair of a ventral hernia is increasingly being performed by a laparoscopic approach despite lack of good long term follow up data on outcomes. The aim of this study was to examine the long term performance of a polyester mesh and to assess its elastic properties in patients undergoing laparoscopic ventral hernia repair. Methods All patients being assessed for a ventral hernia repair between August 2011 and November 2013 were placed on a prospective database. Those undergoing laparoscopic repair with a polyester mesh were seen at clinic at one month and one year, while their electronic records were assessed at 34 months (range 24–48 months) and 104 months (range 92–116 months). In addition, CT scans of the abdomen and pelvis performed for any reason on these patients during the follow up period were reviewed by a consultant gastrointestinal radiologist. Mechanical failure testing of the mesh was also performed. Results Thirty-two of the 100 patients assessed for ventral hernia repair had a laparoscopic repair with a polyester mesh. Nineteen (59%) had CT scans performed during the follow-up period. No recurrence was recorded at 34 months, while three (9.4%) had a recurrence at 104 months. Two had central breakdown of the mesh at 81 and 90 months, while 1 presented acutely at 116 months after operation. Mesh had stretched across the defect by an average of 21% (range 5.7–40%) in nine patients. Mechanical testing showed that this mesh lost its elasticity at low forces ranging between 1.8 and 3.2 N/cm. Conclusion This study shows that late recurrence is a problem following laparoscopic ventral hernia repair with polyester mesh. The mesh loses it elasticity at a low force. This combined with degradation of mesh seems the most likely cause of failure. This is unlikely to be a unique problem of polyester mesh and further long-term studies are required to better assess this operative approach to ventral hernia repair.
