Randomized Controlled Trial
Effects of preoperative carbohydrates drinks on immediate postoperative outcome after day care laparoscopic cholecystectomy.
Postoperative nausea and vomiting is the most common cause for unexpected hospital admission of patients undergoing day care surgery. Overnight fasting changes patient metabolic state and influences their perioperative stress response. Preoperative carbohydrate loading may have accelerated recovery and better overall outcome after major abdominal surgery. The aim of the study was to investigate the effects of preoperative carbohydrate-rich drinks on postoperative nausea and vomiting and pain after day care laparoscopic cholecystectomy. ⋯ Perioperative consumption of a carbohydrate-rich drink can minimize postoperative nausea, vomiting and pain in patients undergoing outpatient cholecystectomy. Consumption of carbohydrate drinks up to 2 h prior to surgery is not associated with additional complications.

Inattention blindness (IB) can be defined as the failure to perceive an unexpected object when attention is focussed on another object or task. The principal aim of this study was to determine the effect of cognitive load and surgical image guidance on operative IB. ⋯ The overall effect of IB on operative practice appeared to be significant, within the context of this study. When examining for the effects of AR image guidance and cognitive load on IB, only the latter was found to have significance.

Randomized Controlled Trial
Mesenteric defect closure in laparoscopic Roux-en-Y gastric bypass: a randomized controlled trial.
Internal herniation is a potential complication following laparoscopic Roux-en-Y gastric bypass (LRYGB). Previous studies have shown that closure of mesenteric defects after LRYGB may reduce the incidence of internal herniation. However, controversy remains as to whether mesenteric defect closure is necessary to decrease the incidence of internal hernias after LRYGB. This study aims to determine if jejeunal mesenteric defect closure reduces incidence of internal hernias and other complications in patients undergoing LRYGB. ⋯ In this study, closure or non-closure of the jejeunal mesenteric defect following LRYGB appears to result in equivalent internal hernia and complication rates. High index of suspicion should be maintained whenever internal hernia is expected after LRYGB.

Randomized Controlled Trial
Short and long-term outcomes of a randomised controlled trial of vertical periumbilical wound versus transverse left iliac fossa wound for specimen retrieval in laparoscopic anterior resections.
The ideal incision for laparoscopic specimen extraction is not known. There has been no randomised study thus far evaluating extraction site in laparoscopic colorectal surgery. The aim of our study was to compare post-operative outcomes, pain scores and quality of life scores of vertical periumbilical (VW) versus transverse left iliac fossa (TW) incisions for specimen extraction in laparoscopic anterior resections. ⋯ Transverse and vertical incisions in laparoscopic colorectal surgery have similar post-operative outcomes, with similar pain scores, cosmesis scores, quality of life scores and incisional hernia rates.

Randomized Controlled Trial
The efficacy of cefazolin in reducing surgical site infection in laparoscopic cholecystectomy: a prospective randomized double-blind controlled trial.
A prophylactic antibiotic is recommended in open cholecystectomy surgeries, but in laparoscopic cholecystectomies such prophylaxis is controversial. Recent reviews have not found conclusive evidence that routine prophylaxis, especially in low risk patients, is effective. This clinical trial was undertaken to evaluate the efficacy of cefazolin in reducing surgical site infection SSI in laparoscopic cholecystectomies in a sample not screened for high or low risk patients. ⋯ A single dose of preoperative prophylactic cefazolin has no significant benefit in reducing the incidence of SSI in laparoscopic cholecystectomy. Whether or not to use a prophylactic depends on the individual patient, and the consideration of the attending surgeon.
