Background and Aim: Training programs for developing laparoscopic suturing skills range from dry-box training to virtual simulator training. There are advantages and disadvantages to each training method; however, which training is best for medical students and young surgeons is unclear. The aim of this study was to compare the proficiency of medical students in acquiring laparoscopic suturing skills after various routes of short-term training: via a video, an expert teacher, or a virtual simulator. Materials and Methods: Seventeen medical students were registered and divided randomly into three groups: group receiving personal training while watching a training video (video group), group receiving training under the guidance of an expert (teaching group), and group receiving personal training with a virtual simulator (virtual group). The students practiced laparoscopic suturing and tying skills for 1 hour. Following their training, they performed the evaluation task of three sutures and ties using a laparoscopic fundoplication simulator. We developed a 1-year-old infant body model (body weight 10 kg) based on computed tomography data and established a pneumoperitoneum body model based on a clinical situation. Results: The path length of the assistant forceps in the virtual group tended to be longer than in the other groups. The average acceleration of the assistant forceps in the virtual group was faster than in the other groups (P = .04). There were no significant differences in the other evaluation parameters. Conclusion: A long-term and combination training study should be performed to develop the best method for training medical students and inexperienced young surgeons. [ABSTRACT FROM AUTHOR]

Purpose: This study evaluated the stability and risk of single-incision laparoscopic percutaneous extraperitoneal closure (SILPEC) for pediatric inguinal hernia performed by inexperienced pediatric surgeons versus conventional LPEC procedure.Methods: Between 2011 and 2012, a randomized prospective study was performed comparing SILPEC (n = 37, 16 uni- and 21 bilateral patent processus vaginalis [PPV]) to LPEC (n = 72, 39 uni- and 33 bilateral PPV). The procedures were performed in girls with inguinal hernia by inexperienced pediatric surgeons with the assistance of an expert pediatric surgeon. In SILPEC, a laparoscope was placed through a transumbilical incision. A 2-mm trocar for the grasper was inserted through the same incision and introduced into the extraperitoneal cavity. The tip of the trocar was inserted in the abdominal cavity distant from the umbilical incision by the expert surgeon to avoid any complications caused by the in-line view. Using a special needle, the hernial sac was closed extraperitoneally by the inexperienced surgeon. A statistical survey of the mean age at operation, mean operative time, intra- and postoperative complications, and recurrence in the SILPEC and LPEC groups was performed.Results: There were no significant differences in the mean age or operative time. There were fewer total number of postoperative complications in the SILPEC group compared with the LPEC group (P = .0707). No intraoperative complications or recurrence occurred.Conclusions: Considering the risks and need to improve endoscopic surgical skills with useful instruments specialized for SILPEC, inexperienced surgeons can successfully perform SILPEC safely under expert pediatric surgeons.
