Randomized Controlled Trial Multicenter Study Comparative Study
Recurrence and complications after laparoscopic versus open inguinal hernia repair: results of a prospective randomized multicenter trial.
The aim of this prospective randomized multicenter trial was to evaluate the recurrence rates and complications of open versus laparoscopic repairs of inguinal hernias. ⋯ In this multicenter study, no significant difference in the recurrence rate and complications between laparoscopic and open methods of hernia repair was revealed.

Comparative Study
Ventralex mesh in umbilical/epigastric hernia repairs: clinical outcomes and complications.
Umbilical and epigastric hernias have historically been repaired without mesh resulting in recurrence rates in some series of up to 40%. Recent data suggests mesh repair of these hernias may decrease recurrent hernia rates. Ideal placement of the mesh is behind the defect, which is difficult to do without a large incision in these hernias unless done laparoscopically. The Ventralex hernia patch is a composite PTFE/polypropylene patch allowing intraperitoneal placement behind the hernia defect through a small incision, and without the cost of laparoscopy. To date, only one study exists evaluating this new prosthesis. ⋯ The composite PTFE/polypropylene hernia patch is effective in preventing hernia recurrence in umbilical, epigastric, and small ventral hernia repairs and can be accomplished with a low rate of complications.

Comparative Study
Laparoscopic ventral hernia repair (LVHR) in morbidly obese patients.
The aim of this study was to evaluate our experience with LVHR in morbidly obese patients (BMI >40) and to compare their outcomes to those of patients with lower BMI. ⋯ LVHR in the morbidly obese population is both safe and feasible, although there is a higher, but still acceptable recurrence rate. Despite the increased risk for recurrence, LVHR in morbidly obese patients minimizes the potential wound and mesh complications that frequently occur for open mesh repair in this group of patients.

Randomized Controlled Trial
The effect of supplemental 70% oxygen on postoperative nausea and vomiting in patients undergoing inguinal hernia surgery.
Postoperative nausea and vomiting (PONV) are among the leading side-effects after surgery performed under general anaesthesia. The role of oxygen as an important method for treatment of PONV was studied. The aim of this study was to compare intraoperative 30% oxygen with 70% oxygen for improvement of PONV in patients undergoing inguinal hernia surgery. ⋯ Supplemental oxygen effectively prevents postoperative nausea and vomiting after inguinal hernia surgery: the higher the arterial oxygen saturation, the less frequent PONV.

Several tools for pain measurement including a Visual Analogue Scale (VAS) and a Verbal Rating Scale (VRS) are currently used in patients with chronic pain. The aim of the present study was to determine which of these two pain tests performs optimally in patients following groin hernia repair. ⋯ Because of lower scale failure rates and overlapping VAS scores per VRS category, the VRS should be favored over the VAS in future postherniorrhaphy pain assessment. If VAS is preferred, the presented cut-off points should be utilized.
