Laparoscopic ventral hernia repair may be an alternative to open mesh repair as it avoids a large abdominal incision, and thus potentially reduces pain and hospital stay. This review aimed to assess the safety and efficacy of laparoscopic ventral hernia repair in comparison with open ventral hernia repair. ⋯ Based on current evidence, the relative safety and efficacy of the laparoscopic approach in comparison with the open approach remains uncertain. The laparoscopic approach may be more suitable for straightforward hernias, with open repair reserved for the more complex hernias. Laparoscopic ventral hernia repair appears to be an acceptable alternative that can be offered by surgeons proficient in advanced laparoscopic techniques.

Randomized Controlled Trial
Epidural analgesia diminished pain but did not otherwise improve enhanced recovery after laparoscopic sigmoidectomy: a prospective randomized study.
The primary hypothesis for this study was that epidural analgesia reduces the use of opioids and thus advances bowel function and oral intake and shortens hospital stay after laparoscopic sigmoidectomy performed according to principles of enhanced recovery after surgery. ⋯ Epidural analgesia significantly alleviates pain, reducing the need for opioids during the first 48 h after laparoscopic sigmoidectomy. However, epidural analgesia does not alter postoperative oral intake, mobilization, or length of hospital stay.

Controlled Clinical Trial
Transanal endoscopic operation for rectal lesions using two-dimensional visualization and standard endoscopic instruments: a prospective cohort study and comparison with the literature.
The transanal endoscopic operation (TEO) has proved to be an effective alternative to conventional surgery for the treatment of rectal lesions. The TEO procedure offers reduced morbidity, faster recovery and equivalent oncologic outcome. Currently, two instrument sets are available: one with three-dimensional (Wolf) and one with two-dimensional (Storz) optic capacities. The three-dimensional (3D) instrument set is considered the golden standard. Although the advantages of TEO are imposing, the procedure with the 3D armamentarium has certain technical and financial drawbacks. This study therefore aimed to compare results for the TEO 2D alternative with recently published results for 3D TEO. ⋯ The study findings showed that for rectal tumors located up to 15 cm from the anal verge with a maximal diameter of 5 cm, TEO using standard laparoscopic instruments with a 2D view is feasible and provides results comparable with those associated with a 3D view and dedicated instruments. Furthermore, the 2D procedure can be performed with improved ergonomics due to movable monitors and is considerably less expensive.

Controlled Clinical Trial
Simulation in laparoscopic surgery: a concurrent validity study for FLS.
Current assessments using the fundamentals of laparoscopic surgery (FLS) tasks are labour intensive and depend heavily on expert raters. Hand motion analysis may offer an alternative method of objective evaluation of FLS performance. ⋯ There is a high correlation between FLS standard scoring and motion efficiency metrics. The use of ICSAD for the objective assessment of FLS tasks may in the future offer an adjunctive method of evaluation. ICSAD metrics are potentially less labour intensive due to the instant and fully automated computerized scoring that it provides.

Computer-based laparoscopic and robotic surgical simulators: performance characteristics and perceptions of new users.
This study aimed to define perceptions of the need and the value of new simulation devices for laparoscopic and robot-assisted surgery. The initial experience of surgeons using both robotic and nonrobotic laparoscopic simulators to perform an advanced laparoscopic skill was evaluated. ⋯ The task completion rate was the best discriminant of expert performance on both virtual reality platforms, whereas simulator metrics best discriminated expertise for the videoscopic platform. Similar comparisons for the virtual reality platforms were not feasible because of the low task completion rate for nonexperts. The added degrees of freedom associated with the robotic surgical simulator instruments facilitated completion of the task by nonexperts. All platforms were perceived as effective training tools.
