Are intra-operative gastric drainage procedures necessary in esophagectomy: a systematic review and meta-analysis.

Purpose: Surgical pyloroplasty or pyloromyotomy are often performed during esophagectomy with a view of improving gastric conduit drainage. However, the clinical importance of this is not clear, and some centers opt to omit this step. The aim of this meta-analysis is to compare the rates of pulmonary complications, anastomotic leak, mortality, delayed gastric emptying, and the need for further pyloric intervention, in patients undergoing esophagectomy with and without a drainage procedure.

Minimum Electromyographic Burst Duration in Healthy Controls: Implications for Electrodiagnosis in Movement Disorders.

Background: Electromyogram (EMG) burst duration can provide additional diagnostic information when investigating hyperkinetic movement disorders, particularly when a functional movement disorder is suspected. It is generally accepted that EMG bursts <50 milliseconds are pathological.

Objective: To reassess minimum physiological EMG burst duration.
