Randomized Controlled Trial
Effects of preemptive analgesia in laparoscopic cholecystectomy: a double-blind randomized controlled trial.
This study aimed to investigate the effect of preemptive etoricoxib compared with placebo in laparoscopic cholecystectomy. ⋯ The authors recommend using etoricoxib as a preemptive analgesia to reduce postoperative pain after laparoscopic cholecystectomy.

Randomized Controlled Trial Comparative Study
Comparison of the open tension-free mesh-plug, transabdominal preperitoneal (TAPP), and totally extraperitoneal (TEP) laparoscopic techniques for primary unilateral inguinal hernia repair: a prospective randomized controlled trial.
The open tension-free mesh-plug hernia technique, transabdominal preperitoneal (TAPP) technique, and totally extraperitoneal (TEP) laparoscopic technique all are common surgical procedures for primary unilateral inguinal hernia repair. However, the choice of the right surgical procedure still is controversial in China. This study aimed to compare open tension-free hernioplasty with two laparoscopic hernia repairs. ⋯ The findings show that open tension-free mesh-plug hernia repair, TAPP, and TEP are safe and effective for patients with primary unilateral inguinal hernia. Both TAPP and TEP are superior to open repair in terms of less postoperative pain and faster recovery time. The authors therefore recommend laparoscopic repair techniques as the preferable choice of surgical procedure. However, they think open repair will remain a practical solution in China because of its lower cost, short learning period, and need for no special equipment.

Multicenter Study
European consensus on a competency-based virtual reality training program for basic endoscopic surgical psychomotor skills.
Virtual reality (VR) simulators have been demonstrated to improve basic psychomotor skills in endoscopic surgery. The exercise configuration settings used for validation in studies published so far are default settings or are based on the personal choice of the tutors. The purpose of this study was to establish consensus on exercise configurations and on a validated training program for a virtual reality simulator, based on the experience of international experts to set criterion levels to construct a proficiency-based training program. ⋯ A European, multicenter, validated, training program was constructed according to the general consensus of a large international team with extended experience in virtual reality simulation. Therefore, a proficiency-based training program can be offered to training centers that use this simulator for training in basic psychomotor skills in endoscopic surgery.

Comparative Study
Overcoming the difficulties in laparoscopic management of contracted gallbladders with gallstones: possible role of fundus-down approach.
The aim of this study is to compare efficacy and complications between fundus-down and conventional laparoscopic cholecystectomy (LC) in treating contracted gallbladders with gallstones. ⋯ It appears that fundus-down laparoscopic cholecystectomy is associated with lower conversion and complication rates and shorter postoperative hospital stay as compared with conventional laparoscopic cholecystectomy when used to treat patients with contracted gallbladders and gallstones.

Five-year graft survival in the pediatric lung transplant (LTxp) population is less than 50%, with obliterative bronchiolitis (OB) the leading cause of death at 1, 3, and 5 years post-transplant. Bronchiolitis obliterans syndrome (BOS), defined using spirometry values, is the clinical surrogate for the histological diagnosis of obliterative bronchiolitis. Surgical correction of documented gastroesophageal reflux disease (GERD) has been proposed as a means to potentially delay the onset of BOS and prolong allograft survival in adults before or after lung transplantation but only one such study exists in children. We have examined the safety and possible benefits of laparoscopic antireflux surgery in pediatric patients following lung (LTxp) and heart-lung transplantation (HLTxp). ⋯ It is feasible to perform laparoscopic Nissen fundoplication in pediatric lung and heart-lung transplant recipients without mortality or significant morbidity for the treatment of GERD. The real effect on pulmonary function cannot be assessed due to our small sample size and lack of reproducible spirometry in our younger patients. Additional studies are needed to elucidate the relationship between antireflux surgery and the potential for improving pulmonary allograft function and survival in children which has been previously observed in adult patients.
