Randomized Controlled Trial Clinical Trial
Randomized study of the benefits of preoperative corticosteroid administration on the postoperative morbidity and cytokine response in patients undergoing surgery for esophageal cancer.
To investigate whether preoperative corticosteroid administration plays a role in attenuating postoperative morbidity. ⋯ The results suggest that prophylactic administration of corticosteroids is associated with a decrease in postoperative morbidity in patients undergoing invasive surgery. The laboratory data suggest that corticosteroids may attenuate surgical stress-induced inflammatory responses both directly by suppressing the release of proinflammatory cytokines and via inducing IL-10 synthesis.

Case Reports Comparative Study
Medical or surgical therapy for erosive reflux esophagitis: cost-utility analysis using a Markov model.
To compare the cost and utility of healing and maintenance regimens of omeprazole and laparoscopic Nissen fundoplication (LNF) in the framework of the Canadian medical system. ⋯ For patients with severe esophagitis, LNF is a cost-effective alternative to long-term maintenance therapy with proton pump inhibitors.

Clinical Trial
Evaluation of hepatic venous congestion: proposed indication criteria for hepatic vein reconstruction.
To establish criteria for venous reconstruction of middle hepatic vein (MHV) tributaries of the right liver graft in adult-to-adult living donor liver transplantation (LDLT). ⋯ The state of venous congestion in the right liver graft can be correctly assessed by the temporary arterial clamping method and intraoperative Doppler ultrasonography. If the venocongestive area is demonstrated to be so large that the graft volume excluding this area is thought to be insufficient for postoperative metabolic demand, venous reconstruction is recommended.

To examine the effect of preoperative radiotherapy (PRT) on patients who undergo rectal resection with total mesorectal excision (TME) for stage T3 low rectal cancers. ⋯ Patients with pT3 low rectal cancers undergoing resection with TME have an improved survival with PRT. The effect is most beneficial for patients with node-negative and 2- to 5-cm tumors, although this group may include larger and node-positive tumors that have been downstaged by PRT. PRT should be advocated for all patients with T3 rectal cancers less than 8 cm from the anal verge, even if the surgery includes a properly performed TME.

To determine the effects of hypothermia and rewarming on changes in the villus microcirculation induced by intestinal ischemia-reperfusion (I/R). ⋯ Hypothermia might prove to be an effective strategy for preventing adverse side effects in clinical settings in which intestinal I/R can be predicted.
