Randomized Controlled Trial Comparative Study Clinical TrialComparison of manual and mechanical cervical esophagogastric anastomosis after esophageal resection for squamous cell carcinoma: a prospective randomized controlled trial.
The use of a circular stapler in cervical esophagogastric anastomosis remains controversial. This study was to compare the postoperative and long-term results of manual and mechanical techniques for cervical esophagogastric anastomosis after resection for squamous cell carcinoma. ⋯ Performing cervical esophagogastric anastomoses using a circular mechanical stapler had a shorter operating time and a comparable outcome to the hand-sewn method. The circular mechanical stapler could be used as an alternative for cervical esophagogastric anastomosis after resection for esophageal squamous cell cancer.

Multicenter StudyThe Aristotle score: a complexity-adjusted method to evaluate surgical results.
Quality control is difficult to achieve in Congenital Heart Surgery (CHS) because of the diversity of the procedures. It is particularly needed, considering the potential adverse outcomes associated with complex cases. The aim of this project was to develop a new method based on the complexity of the procedures. ⋯ A complexity-adjusted method named the Aristotle Score, based on the complexity of the surgical procedures has been developed by an international group of experts. The Aristotle score, electronically available, was introduced in the EACTS and STS databases. A validation process evaluating its predictive value is being developed.

On-pump versus off-pump coronary artery bypass grafting: more heat-shock protein 70 is released after on-pump surgery.
The use of cardiopulmonary bypass in coronary artery bypass grafting (CABG) may contribute to the postoperative inflammatory response. The molecular chaperone heat-shock protein (HSP) 70 may be induced by ischemia, and has been detected both in the myocardium and in the circulation after CABG. In vitro, extracellular HSP70 may activate both innate and adaptive immunity. Hypothesizing that use of cardiopulmonary bypass (CPB) leads to more circulating HSP70, we explored the release of it in 10 patients undergoing CABG with the use of CPB, and in 10 patients undergoing off-pump surgery CABG (OPCAB). ⋯ Significantly more HSP70 was released into the circulation following conventional than following off-pump CABG. Circulating HSP70 may indicate cellular stress or damage. Furthermore, HSPs are suggested as immunoregulatory agents, and may be important in the host defence postoperatively.

To reveal the incidence and clinical significance of mediastinal nodal metastases without N1-station nodal metastases ('skip-N2 metastases') in non-small cell lung cancer (NSCLC). ⋯ N1 nodal status is not a useful predictor of N2 nodal status in NSCLC, because skip-N2 metastases were documented in 18% patients showing no N1-nodal involvement. However, N1 node-guided dissection might be performed in patients with adenocarcinoma showing lower PI, because the incidence of skip-N2 metastases was extremely low.
