Randomized Controlled Trial Multicenter Study
Perioperative prophylaxis with granulocyte colony-stimulating factor (G-CSF) in high-risk colorectal cancer patients for an improved recovery: A randomized, controlled trial.
We aimed to improve the postoperative outcome of high-risk patients (American Society of Anesthesiologists class 3 and 4) recovering from colorectal cancer surgery by using recombinant human G-CSF (filgrastim) as perioperative prophylaxis. ⋯ High-risk patients undergoing major operation for colorectal cancer profited from filgrastim prophylaxis with regard to duration of hospital stay, noninfectious complications, social QoL, and subjective recovery from operation. These endpoints, however, were secondary, and the primary endpoints (overall QoL and the McPeek index) did not show comparable benefits. A new confirmatory trial with the successful endpoints of this trial, as well as a cost analysis, will be needed to confirm the results before a general recommendation for the prophylactic use of G-CSF in high-risk cancer patients can be given.

Randomized Controlled Trial
Teaching suturing and knot-tying skills to medical students: a randomized controlled study comparing computer-based video instruction and (concurrent and summary) expert feedback.
We carried out a prospective, randomized, 4-arm study including control arm, blinding of examiners to determine effectiveness of computer-based video instruction (CBVI) and different types of expert feedback (concurrent and summary) on learning of a basic technical skill. ⋯ Our study showed that CBVI can be as effective as summary expert feedback in the instruction of basic technical skills to medical students. Thoughtfully incorporated into technical curricula, CBVI can make efficient use of faculty time and serve as a useful pedagogic adjunct for basic skills training. Additionally, our study provides evidence supporting an increased role of summary feedback to effectively train novices in technical skills.

Randomized Controlled Trial Comparative Study
Superiority of postoperative epidural over intravenous patient-controlled analgesia in orthopedic oncologic patients.
Surgery for bone malignancy is associated with intense postoperative pain. Patient-controlled epidural analgesia (PCEA) and intravenous patient-controlled analgesia (IV-PCA) are used currently for postoperative pain control. ⋯ Postoperative ropivacaine + fentanyl via PCEA reduces pain better and affords better subjective feelings than IV morphine via PCA after resection of bone malignancy carried out under combined general and epidural anesthesia.

Randomized Controlled Trial Clinical Trial
Continuous local anesthetic infusion for pain management after outpatient inguinal herniorrhaphy.
The purpose of the present study is to compare postoperative pain and functional outcomes in patients undergoing inguinal herniorrhaphy who receive a continuous wound infusion of bupivacaine to those who receive an infusion of saline. ⋯ Continuous infusion of local anesthetic after inguinal herniorrhaphy provides modest improvements in pain scores and functional outcomes when compared with placebo. However, these effects are limited to the first postoperative day only. The additional costs associated with this intervention may limit its widespread use in clinical practice.

Randomized Controlled Trial Comparative Study Clinical Trial
A prospective, randomized, controlled clinical trial of tissue adhesive (2-octylcyanoacrylate) versus standard wound closure in breast surgery.
Recent studies suggest that the use of tissue adhesive for closure of both traumatic lacerations and incisional surgical wounds leads to cosmetic outcome comparable to conventional sutures. To date, no studies have investigated tissue adhesive in breast surgery and costs. Our aim was to compare the tissue adhesive 2-octylcyanoacrylate (OCA) with standard suture in breast surgery. ⋯ OCA is effective and reliable in skin closure for breast surgery, yielding similar cosmetic results to standard suture. OCA is faster than standard wound closure and offers several practical advantages over suture repair for patients. Cost analysis has found that OCA adhesive can significantly decrease health care costs.
