Randomized Controlled Trial
Instructor feedback versus no instructor feedback on performance in a laparoscopic virtual reality simulator: a randomized trial.
To investigate the impact of instructor feedback versus no instructor feedback when training a complex operational task on a laparoscopic virtual reality simulator. ⋯ Instructor feedback increases the efficiency when training a complex operational task on a virtual reality simulator; time and repetitions used to achieve a predefined proficiency level were significantly reduced in the group that received instructor feedback compared with the control group.

Randomized Controlled Trial Comparative Study
Effect of billroth II or Roux-en-Y reconstruction for the gastrojejunostomy on delayed gastric emptying after pancreaticoduodenectomy: a randomized controlled study.
Delayed gastric emptying (DGE) is one of the major complications after pancreaticoduodenectomy (PD), occurring in 14% to 61% of cases. There have been no studies that compare the incidence of DGE in terms of the reconstruction method of gastrojejunostomy performed in subtotal stomach-preserving pancreaticoduodenectomy (SSPPD). The objective of this study was to evaluate the superiority of Billroth II (B-II) to Roux-en Y (R-Y) reconstruction on decreasing the incidence of delayed gastric emptying DGE after SSPPD by a prospective randomized controlled trial. ⋯ It is suggested that the incidence of DGE after SSPPD can be decreased by using B-II rather than R-Y reconstruction for gastrojejunostomy.(Clinical Trials Registry, UMIN-CTR: http://www.umin.ac.jp/ctr/, ref no. UMIN000003535).

Randomized Controlled Trial
Low degree of formal education and musical experience predict degree of music-induced stress reduction in relatives and friends of patients: a single-center, randomized controlled trial.
To determine the factors that may predict music-induced relaxation in friends and family of patients in the emergency department. ⋯ Music is an effective and inexpensive means of reducing anxiety in friends and family of patients, who are underresearched in medicine. Moreover, low educational attainment and tendency to respond positively to music in a group setting can predict the effectiveness of music-induced relaxation.

Randomized Controlled Trial
A double-blind, randomized, controlled trial on surgery for chronic abdominal pain due to anterior cutaneous nerve entrapment syndrome.
To clarify the role of a surgical neurectomy on pain in refractory patients after conservatively treated anterior cutaneous nerve entrapment syndrome (ACNES). ⋯ Neurectomy of the intercostal nerve endings at the level of the abdominal wall is an effective surgical procedure for pain reduction in ACNES patients who failed to respond to a conservative regimen.
