Review Meta AnalysisThe Cerebrovascular Response to Ketamine: A Systematic Review of the Animal and Human Literature.
The aim of the study was to perform a systematic review of the literature on the cerebrovascular/cerebral blood flow (CBF) effects of ketamine in both animal and human subjects. ⋯ Animal models indicate an increase in global CBF and rCBF with ketamine administration, with a trend to vasodilation of medium-sized intracranial vessels through a calcium-dependent mechanism. Human studies display an Oxford 2b, Grading of Recommendation Assessment Development and Education C, level of evidence to support a trend to increased global CBF and rCBF with ketamine administration in both healthy volunteers and elective surgical patients without neurological illness.

Review Meta Analysis
Meta-analysis of the risk of small bowel obstruction following open or laparoscopic colorectal surgery.
One of the potential advantages of laparoscopic compared with open colorectal surgery is a reduction in postoperative bowel obstruction events. Early reports support this proposal, but accumulated evidence is lacking. ⋯ The reduction in postoperative bowel obstruction demonstrates an advantage of laparoscopic surgery in patients with colorectal disease.

Effect of Hospital Volume on Surgical Outcomes After Pancreaticoduodenectomy: A Systematic Review and Meta-analysis.
The aim of the study was to evaluate the relationship between hospital volume and outcome after pancreaticoduodenectomy (PD). ⋯ This meta-analysis included studies from different countries with disparate health care systems and provided strong evidence for an inverse association between higher hospital volume and lower mortality after PD. Variations in HVH cutoff values across studies majorly influenced the overall heterogeneity.

Review Meta AnalysisLaparoscopic versus open transhiatal oesophagectomy for oesophageal cancer.
Surgery is the preferred treatment for resectable oesophageal cancers, and can be performed in different ways. Transhiatal oesophagectomy (oesophagectomy without thoracotomy, with a cervical anastomosis) is one way to resect oesophageal cancers. It can be performed laparoscopically or by open method. With other organs, laparoscopic surgery has been shown to reduce complications and length of hospital stay compared to open surgery. However, concerns remain about the safety of laparoscopic transhiatal oesophagectomy in terms of post-operative complications and oncological clearance compared with open transhiatal oesophagectomy. ⋯ There are currently no randomised controlled trials comparing laparoscopic with open transhiatal oesophagectomy for patients with oesophageal cancers. In observational studies, laparoscopic transhiatal oesophagectomy is associated with fewer overall complications and shorter hospital stays than open transhiatal oesophagectomy. However, this association is unlikely to be causal. There is currently no information to determine a causal association in the differences between the two surgical approaches. Randomised controlled trials comparing laparoscopic transhiatal oesophagectomy with other methods of oesophagectomy are required to determine the optimal method of oesophagectomy.

Review Meta Analysis Comparative Study
Effect of restrictive versus liberal transfusion strategies on outcomes in patients with cardiovascular disease in a non-cardiac surgery setting: systematic review and meta-analysis.
To compare patient outcomes of restrictive versus liberal blood transfusion strategies in patients with cardiovascular disease not undergoing cardiac surgery. ⋯ Randomised controlled trials involving a threshold for red blood cell transfusion in hospital. We searched (to 2 November 2015) CENTRAL, Medline, Embase, CINAHL, PubMed, LILACS, NHSBT Transfusion Evidence Library, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, ISRCTN Register, and EU Clinical Trials Register. Authors were contacted for data whenever possible.
