Randomized Controlled Trial Comparative Study
Single-center, single-blinded, randomized study of self-gripping versus sutured mesh in open inguinal hernia repair.
The primary aim of the present study was to evaluate whether usage of self-gripping mesh in open inguinal hernia repair, compared with standard Lichtenstein repair with sutured mesh, could result in a decreased rate of chronic pain at 6-mo follow-up. The secondary outcome was to evaluate foreign body feeling and the quality of life after inguinal hernia repair. ⋯ Self-gripping mesh compared with standard Lichtenstein operation has no advantages in reducing chronic pain 6-mo after surgery. The rate of foreign body feeling was higher in the self-gripping mesh group. Scores of bodily pain, physical functioning, and physical role improved significantly in both study groups after hernia surgery.

Randomized Controlled Trial
Effects of dexmedetomidine on patients undergoing radical gastrectomy.
Surgical stress may cause immunosuppression especially in patients who have surgery for primary tumor removed. This study aimed to explore the effects of dexmedetomidine on immune and inflammatory response in patients undergoing radical gastrectomy. ⋯ Dexmedetomidine has been shown to reduce surgical stresses and maintain Th1/Th2 balance. It has been shown to reduce inflammatory responses and exerts immunoprotective effect.

Postoperative fatigue (POF) is an important complication that is commonly observed postoperatively and is also one of the most serious obstacles to postoperative convalescence. However, the risk factors for POF have not been fully addressed, and there is no effective method to predict POF. The aim of the present study was to investigate the risk factors for POF and to explore prediction of the degree of POF. ⋯ Old age, nutritional risk screening 2002 score ≥ 3 and gastrectomy were risk factors for POF in patients undergoing elective gastrointestinal surgery. POF was reduced in laparoscopic-assisted surgery. Consideration of these factors could be important for the prevention and treatment of POF.

The purpose of this study was to assess the direct and indirect relationships between first-case tardiness (or "late start"), turnover time, underused operating room (OR) time, and raw utilization, as well as to determine which indicator had the most negative impact on OR utilization to identify improvement potential. Furthermore, we studied the indirect relationships of the three indicators of "nonoperative" time on OR utilization, to recognize possible "trickle down" effects during the day. ⋯ The study findings clearly suggest that OR utilization can be improved by focusing on the reduction of underused OR time at the end of the day. Improving the prediction of total procedure time, improving OR scheduling by, for example, altering the sequencing of operations, changing patient cancellation policies, and flexible staffing of ORs adjusted to patient needs, are means to reduce "nonoperative" time.

The incidence of splenectomy after trauma is institutionally dependent and varies from 18% to as much as 40%. This is important because variation in management influences splenic salvage. The aim of this study was to investigate whether differences exist between Dutch level 1 trauma centers with respect to the treatment of these injuries, and if variation in treatment was related to splenic salvage, spleen-related reinterventions, and mortality. ⋯ Although observation rates were comparable among the academic trauma centers, embolization and surgery rates varied. A nearly 5-fold increase in the odds of operative management was observed in one hospital, and another hospital had significantly lower odds of splenic salvage. The development of a national guideline is recommended to minimalize splenectomy after trauma.
